Invention process 1928 transparent tape Richard Drew, St. Paul, Minnesota, USA 1928 was filed in Britain and the United States on May 30, 2008. Drew developed a light pressure-sensitive adhesive. The initial attempt was not sticky enough, so Drew was told, "Take this back to your Scottish boss and ask them to apply more adhesive!" ("Scotland" means "stingy" However, during the Great Depression, people found hundreds of uses of this tape, from mending clothes to protecting broken eggs. How to use the adhesive tape The adhesive tape consists of two parts: the base material and the adhesive, and two or more unconnected objects are connected together by bonding. Its surface is coated with an adhesive. The earliest adhesives came from animals and plants. In the19th century, rubber was the main component of adhesives. In modern times, various polymers are widely used. Adhesives can stick to things because they form bonds between their own molecules and those of the objects to be connected, which can firmly stick the molecules together. The composition of adhesive, according to different brands and types, has different polymers. Classification can be divided into BOPP tape, duct tape tape, kraft paper tape, textured paper tape, fiber tape, PVC tape, pe foam tape, etc. According to the scope of application, it can be divided into warning tape, carpet tape, electrical tape, protective film paper tape, wrapped film tape, box sealing tape, module tape and so on. According to the market penetration, it can be divided into ordinary tape and special tape. According to the application environment temperature, it can be divided into low temperature tape, normal temperature tape and high temperature tape. According to the adhesiveness, it is divided into single-sided adhesive tape and double-sided adhesive tape. Specification 1) Jumbo Roll main roll is a prototype tape coming down from the machine, with a width of 1 m to 1.5 m and a length of several hundred meters to several thousand meters, depending on different substrates. 2)2) The log roll is the product of rewinding the master roll, with the same width and different lengths (generally 100m, 50m, 25m, 10m, 5m). 3) slitting roller (finished roller) is a product in the general market. The single-sided adhesive tape can be used for packaging or temporarily fixing objects, and can be easily torn off without any tools. After tearing off, there is no colloid residue on the adhered surface. A new type of single-sided adhesive tape based on embossed PVC was developed. It can partially replace the existing waterproof cloth-based single-sided adhesive tape S9522R or 470 1 in function, and the price is more competitive. The adhesive tape has been tried in stores in beijing east road, and the available color in the early stage is khaki, which can be tailored according to customer specifications. S8855B heat sealing adhesive tape is a kind of adhesive tape which is heated by special equipment (hot air seam sealing machine or high frequency heat sealing machine) and sewed at the pin holes of knitted bones of waterproof and air-proof series products such as raincoats, tents and lift-off balloons, so as to achieve the sealing (water and air leakage prevention) effect. As we all know, there will be pinholes in garment processing and production, and waterproof series is no exception. How to ensure that these pinholes don't leak water, this seemingly simple problem has also troubled us for thousands of years, because ordinary tape has no adhesion when it meets water. But in the 20th century, only a few countries in the world used it, and the materials were very expensive. It only appears in countries with relatively developed military industries such as the United States and the Soviet Union, and it is only used in space science and technology. It is even more confidential to other countries. Types of heat sealing tape: PVC, composite PU, pure PU(TPU), hot melt film, rubber tape, non-woven tape and three-layer cloth tape. Technical standard of heat sealing tape: European toxic element EN7 1. PART3: 1994 safety inspection standard eu toxic element en122: 2001safety inspection standard eu 2002/6 1/ EC restricts the use of vinyl chloride monomer heat-sealing tape in the melamine dye standard: heat-sealing tape is widely used in winter clothes, ski clothes, and so on. A series of waterproof products, such as raincoats and motorcycle raincoats, such as butyl rubber waterproof sealant tape, belong to Wuhua (hardware gluing/chemical industry) butyl 1. It is an environment-friendly solvent-free sealant material produced by mixing butyl rubber, polyisobutylene and other main raw materials according to a special production formula, adopting the latest patented technology and selecting high-quality special polymer materials (imported) through a special technological process. 2.

In the sun. 1928 On May 30th, an application was filed in Britain and America, and Drew developed a very light pressure-sensitive adhesive. The adhesive tape is the adhesive tape that we use every day. On the basis of the original BOPP film, it is roughened by high-voltage corona, then coated with glue, and then divided into small rolls. Adhesive tape is acrylic adhesive, also called pressure sensitive adhesive, and its main component is tincture. Tincture is a kind of polymer active substance, and the temperature has a certain influence on the molecular activity. The tincture content of glue directly affects the use of adhesive tape. The initial adhesion of normal sealant tape is ≥ 13 (number of steel balls), and the thickness of this adhesive tape is generally 22 microns, which meets the standard thickness. For colored tape, it is convenient for marking and shielding purposes, generally beige and khaki are more. The color of colored tape is the color of glue. Squeeze the cellophane tape tightly and then pull it away quickly, so that the glue on one side can be torn off and the purity and transparency of the original film can be seen. Insulating tape refers to the tape used by electricians to prevent leakage and play an insulating role. Manufacturing process of insulating tape: PVC film is used as the base material and coated with rubber pressure sensitive adhesive. Insulating rubber tape refers to the tape used by electricians to prevent leakage and play an insulating role. Adhesive tape, also known as insulating tape, consists of baseband and pressure-sensitive adhesive layer. Baseband is generally made of cotton cloth, synthetic fiber fabric and plastic film, and adhesive layer is made of rubber and tackifying resin, which has good adhesion and excellent insulation performance. Insulating tape has good insulation and pressure resistance, flame retardant, weather resistance and other characteristics, and is suitable for wire connection, electrical insulation protection and other characteristics. Insulating tape is widely used in electrical work, such as binding, joint and insulation sealing of wires used at 380 volts. There are two production processes: gluing and gluing. Manufacturing process: PVC film as the base material, coated with rubber pressure sensitive adhesive. In the process of using electricity, although people have noticed that the cross-sectional area of power cord materials has an impact on the safe use of electricity, they often pay insufficient attention to the use of insulating tape for connectors. At present, the laying of power lines is becoming more and more complicated, including under wooden floors, in walls, in partitions and in damp underground or water. Improper use of insulating tape will lead to leakage and endanger personal safety. Therefore, in order to use the insulation tape correctly, the power cord connectors are divided into "+"type connection, "-"type connection and "T" type connection. The joint should be wrapped firmly, smoothly and without burr, otherwise, before disconnecting the thread end, it should be lightly pressed with wire pliers, then wound around the pressure mouth, and then swung from side to side, and the thread end can be easily disconnected at the joint. If the joint is in a dry place, firstly wrap 2 layers with insulating vinyl cloth, then wrap 2 layers with plastic tape, then wrap 2-3 layers with insulating self-adhesive tape stretching about 200%, and finally wrap 2 layers with plastic tape. Because the direct use of plastic tape has many disadvantages: plastic tape is easy to be misplaced and opened after a long time; When the electrical appliance is under heavy load, the joint is heated, and the plastic belt is easy to melt and shrink; The power connectors are pressed against each other in the junction box. When the connector has burrs, it is easy to puncture the plastic belt. These hidden dangers will directly endanger personal safety and cause short circuit and fire. However, when using insulating black tape, the above situation will not occur. It has certain strength and flexibility, can be tightly wrapped around the joint for a long time, and can be tightly molded due to the influence of time and temperature, and will not fall off, so it is flame retardant. Furthermore, it can be moisture-proof and rust-proof by wrapping it with insulating black tape and then wrapping it with plastic tape. Of course, the insulating self-adhesive tape also has defects. Although waterproof, it is easy to break. So finally, two layers of plastic tape should be wrapped as a protective layer, and the insulating self-adhesive tapes of the joint do not stick to each other, so the performance is better. Anti-corrosion tape refers to the tape used for anti-corrosion winding, which is divided into cold winding tape and hot winding tape. Cold-wound tapes generally include polyethylene (composite) anticorrosive tape, polypropylene reinforced fiber anti-ultraviolet anticorrosive tape for aluminum foil, polyethylene 660 (modified asphalt) tape, double-sided adhesive tape (this tape is rarely used in China, but it is very practical and widely used abroad, and is generally used for export) and epoxy coal tar pitch anticorrosive tape. The implementation standards are SY/T04 14-98 and SY/T0447-96. Hot winding tape, also known as radiation crosslinked polyethylene heat shrinkable winding tape, can only be used when the adhesive is melted by heating, and sometimes it needs the assistance of solvent-free epoxy paint to become a three-layer structure anticorrosion. The implementation standard is SY/T04 13-2002. Anti-corrosion tape is a kind of metal foil or conductive cloth with high conductive tape. The conductive adhesive tape and the conductive substrate form a complete conductor, which can be bonded with any metal surface to complete electric lap joint and gap sealing. Forbidden conductive tape is an economical and convenient forbidden material. It is used to seal the seams of EMI-forbidden rooms, enclosures and electronic equipment, prohibit the winding of cables, provide a reliable grounding surface, and provide electrical contact for surfaces that cannot be welded. Mara name: Mara tape, also known as silicone Mara tape, fire cow tape, Mara tape. Mara tape application: insulation in electronic industry.

Color: There are five distinct colors: red, blue, yellow, white and black. Composite working temperature range of iron sheet: -40℃- 100℃. Application of iron sheet composite adhesive tape: joints between buildings, bridges, rapid traffic and underground concrete. Features: waterproof, high bonding strength, high tensile strength, and strong adaptability to interface deformation and cracking. It has excellent chemical resistance, weather resistance and corrosion resistance, does not flow at 80℃ and does not crack at 40℃. Polyimide polyimide tape, also known as Kapton tape, is based on polyimide film and imported silicone pressure-sensitive adhesive, and has the properties of high and low temperature resistance, acid and alkali resistance, solvent resistance, electrical insulation (H grade) and radiation protection. Suitable for wave soldering tin shielding of electronic circuit boards, protecting gold fingers and high-grade electrical insulation, motor insulation, lithium battery anode and cathode and ear fixation. Polyimide tape foam tape is coated with pe or eva as the base material, acrylic oil-based pressure sensitive adhesive and release paper or film as the isolation surface. Its performance is: it can fully absorb the gap of the adherend, overcome the uneven defect of the adherend, and has good cushioning performance, excellent creep resistance and long-term load bearing. Widely used in the construction industry and automobile industry. Floor 1, tape should be stored in the warehouse to avoid sun and rain; It is forbidden to contact with organic solvents such as acid, alkali and oil, and keep them clean and dry. From the discovery device 1m, the room temperature is between-15℃ and 40℃ Tape 2. Tape should be placed in rolls and cannot be folded. If it is stored for too long, it should be turned over once every season. 3. When loading and unloading the conveyor belt, it is best to use a crane and lift it smoothly with rigging with beams to avoid damaging the belt edge. Don't load and unload at will, which will make the coil and sleeve loose. 4. The types and specifications of adhesive tape should be reasonably selected according to the use needs and specific conditions. 5. Do not connect (match) tapes of different varieties, specifications, models, strengths and cloth layers. 6, conveyor belt joint had better use thermal vulcanization adhesive joint, in order to improve reliability and maintain high effective strength. 7. The diameter of the conveyor drum and the minimum pulley diameter of the conveyor belt shall comply with relevant regulations. 8, don't make the tape snake or peristalsis, to keep the drag roll, vertical roll flexible, moderate tension. 9. When the conveyor is equipped with a baffle and a cleaning device, wear of the adhesive tape should be avoided. 10, cleanliness is the basic condition for the good operation of the belt, and foreign objects will affect the eccentricity, tension difference and even fracture of the belt. 165438+ high temperature and high temperature adhesive tape, that is, adhesive tape used in high temperature working environment. Mainly used in electronic industry, its temperature resistance is usually between 120 and 260 degrees. It is often used for processing, coating shielding and fixing of paint and baked leather in the process of shielding electronic parts, printed circuit boards and high temperature treatment. High temperature adhesive tape includes KAPTON high temperature adhesive tape; PTFE high temperature adhesive tape; High temperature masking tape; PET green high temperature adhesive tape; High temperature double-sided adhesive tape, etc. Adhesive tape High temperature adhesive tape has the following characteristics: 1, non-stick; 2, high and low temperature resistance, and the temperature resistance of the product can reach 260 DEG C after long-term use; 3.

Low friction and wear resistance; Anti-static warning floor tape 5, moisture-proof and high insulation; High-temperature adhesive tape is mainly used for: 1, insulation cladding of wire and cable industry; 2. Insulating lining of electro-oxygen industry; 3. The surface coating of the roller of the storage tank and the lining of the friction surface of the guide rail can be directly attached to various large planes and regular curved surfaces (such as rollers), so that the operation is simple, and the restrictions of special equipment, special technology and transportation to a professional spraying factory for processing are eliminated; 4. Textile, food, medicine, wood processing and other departments are used as insulating high-temperature materials; 5. Color printing packaging machine, microwave drying of plastic woven wire drawing machine, various conveyor belts, various bag-making machines in the garment hot-pressing sealing and packaging industry, hot-pressing sealing end faces of sealing machines, etc. There are many kinds of adhesive tapes, and there are many kinds of adhesives on the surface, so the performance and strength of various brands of adhesive tapes are different. Therefore, the following factors need to be considered when purchasing the adhesive tape: Microporosity of the adhesive tape: The adhesive effect of the adhesive tape occurs because the moisture of the adhesive on the surface of the adhesive tape quickly dries into adhesive after bonding, making the adhesive tape a part of the adhesive. Therefore, the micro-pores on the surface of the adhered object are very important for the selection of adhesive tape. If there are many micropores, you must use the adhesive tape with rapid solidification, otherwise you must use the adhesive tape with slow solidification speed or more adhesive. Glue on the surface of the adhesive tape: the adhesive is coated on the bottom tape of the adhesive tape in the manufacturer, and is generally arranged into a roll after being fully dried. If the tape is too wet, the tape itself will stick tightly together, which is difficult to open when used, and some of them are not used at all. Choose and distinguish the common sealing tape (BOPP biaxially stretched polypropylene) in daily life, which is an indispensable daily necessities for any enterprise, company and individual. However, compared with the domestic situation, although there are many manufacturers, the technology is uneven. Moreover, the technical content of domestic tape industry is still at a very low stage, and the country has not yet made a clear choice. People's understanding of adhesive tape is often in a very ignorant stage, thinking that the price is low and the viscosity is good. In fact, these are all wrong understandings and judgments. So how to choose the quality of adhesive tape? In fact, there are two standards for the quality of the adhesive tape in use, one is the initial adhesion and the other is the retention, and the two are inversely proportional. Under normal circumstances, tapes smaller than 10 are coated with glue, generally only about 20 microns, such as stationery tapes and ordinary publicity tapes. The initial adhesion of normal sealant tape is between 15-20, and the thickness of this adhesive tape is generally 22-28 microns. This is the standard thickness. However, most of the adhesive tapes on the market are mixed with impurities, so the thickness increases. In order to cover up the impurities, the glue is also mixed with toner, so the transparent tape appears egg yellow and light green. This kind of tape is generally inferior. How to distinguish the quality of colored tape? Color tape, yellow and khaki are generally more. Squeeze the glue tightly and then pull it away quickly, so that one side of the glue can be pulled off and the purity and transparency of the original film can be seen. You can also look at the thickness of the glue. If the glue is not pulled or pulled into dots, there are many impurities in the glue, and the glue has no cohesion. Second, there is too much water, which has evaporated. At this time, the initial adhesion of this tape has been greatly reduced, and the feel can be distinguished. In fact, there are many ways to distinguish between good and bad tape. As long as you pay more attention in your life, you can tell whether the tape is good or bad. When uncovering the tape, it is easy to stick surface items such as wall skin by the way. At this time, after ironing with a steam iron, the tape will be reduced, and it can be torn off with a gentle tear, without damaging the wall and other items. The classification and distribution of supply chains of related enterprises in the world are summarized as follows: First-line brands: American 3M, German TESA and Japanese Nitto all have factories in China, but high-tech products are generally produced locally; Second-tier brands: third-tier brands such as Scapa in the UK, Jishui in Japan, Sigang in Japan and Sony in Japan: the development of tape companies in Taiwan Province Province and mainland China. With the development of economy and the progress of science and technology, China has become a processing factory and a big consumer of adhesive industry in the world. Combined with years of supporting experience. The annual growth rate is 16%. Especially adhesive tapes, protective films and stickers, are widely used in electronics, communication, packaging, construction, papermaking, carpentry, aerospace, automobile, textile, metallurgy, machinery manufacturing, medical industry and so on. Adhesive industry has become the most dynamic and important industry in China chemical industry. The development of adhesive tape industry mainly depends on the development of coal, steel, cement, ports, mines, petroleum, automobiles, textiles, light industry, machinery and other industries. Since the "Eleventh Five-Year Plan", China's national economy has developed rapidly, which has promoted the sustained and rapid growth of coal, steel, cement, automobile, agricultural machinery and other industries. The output of coal, steel and cement in China ranks first in the world. At the same time, the country's measures to expand domestic demand are expected to last for a long time, which will undoubtedly promote the development of building materials, automobiles, agricultural machinery, light industry and other industries. In addition, the emphasis on "agriculture, countryside and farmers" will also be carried out for a long time, which has opened up a broad long-term potential market for the tape work in China. Automobile adhesive tape is the fastest growing variety, which is closely related to the rapid development of China automobile industry. Automobile industry is the pillar industry of China's national economy. In 2009, China's automobile production and sales reached130,000 respectively, ranking first in the world. In the first eight months of 20 10, China's automobile production and sales broke through 1 1 10,000 vehicles, reaching a record high and becoming the largest automobile consumer in the world. According to the prediction of China Machinery Industry Federation and China Automobile Industry Association, China's automobile production and sales will exceed160,000 in 20 10, and the growth rate of automobile production and sales will slow down in the next few years, but it will remain above 10%. After more than 50 years of development, China's automobile industry has basically established a relatively complete automobile industry production system. Driven by the reform and opening-up policy and encouraged by the strong domestic market, it has achieved rapid development, and China's automobile and parts exports have also shown a rapid development trend, with an average annual growth of nearly 50% from 20065438 to 2009. In 2009, the export of automobile products has reached more than 30 billion US dollars. The international comparative advantage of China's automobile products still exists, and the demand potential in the international market is huge. It is predicted that the output value of flame-retardant conveyor belt and V-belt consumed by coal industry will increase by double digits every year. The petroleum industry is one of the important industries in the national economy, with stable development and an annual growth rate of about 7%. Especially when the exploitation of offshore oil wells begins, the demand for adhesive tapes will increase. With the acceleration of capital construction in China, the number of construction machinery is increasing. The annual output of construction machinery in China includes loaders, rollers, graders and excavators. , an increase of about 65,438+00%, and the demand for various major construction machinery is above100000 units. It is estimated that a large number of construction machinery will be needed in recent years, which will bring great opportunities for supporting tapes of construction machinery. With the improvement of agricultural mechanization in China, the output of agricultural machinery has increased year by year, and the adhesive tape for agricultural machinery is a big market.
