Chemical Materials What is New Beric?

It's acrylic, right

What is acrylic?

1. The word "acrylic" may sound strange, because it is a new word that appeared in the mainland only in the past two years. Until 2002, it is in the advertising industry, furniture industry, handicrafts industry is gradually understood by a few people. Acrylic" is a transliteration of foreign words, English is ACRYLIC, it is a chemical material. The chemical name is called "PMMA" belongs to the class of acryl alcohol, commonly known as "specially treated plexiglass", in the application of the industry, its raw materials are generally in the form of particles, plates, tubes, etc.

2. Acrylic sheet and plexiglass?"" Plexiglass" from the English Organic?Glass. In recent years in some areas of all the transparent plastic made of sheet collectively referred to as plexiglass, in fact, this is wrong, acrylic is a pure polymethyl methacrylate (PMMA) material, and the PMMA sheet called acrylic sheet.

3. Acrylic sheet characteristics and advantages? Acrylic has a high degree of transparency, light transmission rate of 92%, "plastic crystal" reputation. And excellent weather resistance, especially for outdoor applications, the crown of other plastics, and both good surface hardness and gloss, processing plasticity, can be made into a variety of shapes and products needed. Another sheet of a wide variety of colorful (including translucent color plate), another feature is that the thick plate can still maintain a high degree of transparency.

4. History of acrylic? Acrylic (ACRYLIC), commonly known as special treatment of plexiglass. Acrylic research and development, has a history of more than a hundred years. 1872 acrylic polymerization began to be discovered; 1880 polymerization of methacrylic acid is known; 1901? In 1901, the synthesis of acrylic polyacrylate research was completed; in 1927, the use of the aforementioned synthesis to try to industrialize the manufacture of the method; 1937, the development of industrial manufacturing of methacrylate, thus entering the large-scale manufacture. During World War II due to acrylic has excellent toughness and translucency, first, was used in aircraft windshields, tank drivers cab vision mirror. 1948 the world's first acrylic bathtub was born, marking the application of acrylic into a new milestone.

Introduction to acrylic

Acrylic by the English Acrylics phonetic translation from the Acrylics acrylics and methacrylics class of chemicals commonly known. Including monomers, sheets, granules, resins and composites, acrylic sheet by methyl methacrylate monomer (MMA) polymerization, that is, polymethylmethacrylate (PMMA) sheet Plexiglas, "Plexiglas" from the trade name "Oroglas Oroglas" (a PMMA sheet), from "Organic?Glass" (i.e., Plexiglas). But in recent years, all by transparent plastics such as PS, PC, etc. are collectively referred to as plexiglass.

Acrylic production process

acrylic sheet according to the production process can be divided into casting type and extrusion type, casting type of sheet performance than extrusion type to be better, the price is also more expensive, casting type of sheet is mainly used for carving, decoration, crafts production, extrusion type is usually used for advertising signs, light boxes and other production.

Acrylic sheet and plexiglass

"Plexiglass" comes from the English Organic?Glass. In recent years in some areas will be all the transparent plastic made of sheet collectively referred to as plexiglass, in fact, this is wrong, acrylic is exclusively refers to the pure polymethyl methacrylate (PMMA) material, and the PMMA sheet called pressed glass. PMMA sheet called acrylic sheet.

Acrylic sheet of the characteristics and advantages?

Acrylic has a high degree of transparency, light transmission rate of 92%, "plastic crystal" reputation. And has excellent weather resistance, especially for outdoor applications, the crown of other plastics, and both good surface hardness and gloss, processing plasticity, can be made into a variety of required shapes and products. Another sheet of a wide variety of colorful (including translucent color plate), another feature is that the thick plate can still maintain a high degree of transparency.

History of acrylic

Acrylic (ACRYLIC), commonly known as special treatment of plexiglass. Acrylic research and development, has been more than a hundred years of history. 1872 acrylic polymerization began to be discovered; 1880 methacrylic polymerization is known; 1901?year acrylic polypropionate resin synthesis completed; 1927 using the aforementioned synthesis method to try to industrialize the manufacture of; 1937 methacrylic industrial manufacturing development was successful, and thus enter the scale of manufacturing. During World War II due to acrylic has excellent toughness and light transmission, first, was used in aircraft windshields, tank drivers cab vision mirror. 1948 the world's first acrylic bathtub was born, marking the application of acrylic into a new milestone.

The use of acrylic

PMMA has the advantages of lightweight, inexpensive, easy to mold. Its molding methods are casting, injection molding, machining, thermoforming and so on. Especially injection molding, mass production, simple process, low cost. Therefore, its application is becoming more and more widespread, it is widely used in instrumentation parts, automotive lamps, optical lenses, transparent pipes and so on.

Acrylic is the best new material to manufacture sanitary ware after ceramics. Compared with traditional ceramic materials, acrylic, in addition to unparalleled high brightness, there are the following advantages: good toughness, not easy to break; strong repair, as long as the soft foam dipped in a little toothpaste can be wiped with a new sanitary ware; soft texture, there is no cold winter feeling of the bones; bright colors to meet the pursuit of personality of different tastes. With acrylic production basin, bathtub, toilet, not only exquisite style, durable, and has the role of environmental protection, its radiation and the human body's own bone radiation level is comparable. Acrylic sanitary ware first appeared in the United States, has occupied more than 70% of the international market.

As acrylic production is difficult, high cost, so there are many low-quality and inexpensive substitutes on the market. These substitutes are also known as "acrylic", in fact, is an ordinary organic board or composite board (also known as sandwich board). Ordinary organic board with ordinary plexiglass cracked material plus pigment casting and become, low surface hardness, easy to fade, with fine sand sanding after polishing effect is poor. Composite panels only a very thin layer of acrylic surface, the center is ABS plastic, the use of thermal expansion and contraction is easy to delamination. True and false acrylic, can be identified from the plate section of the subtle color difference and polishing effect?

Characteristics of acrylic sheet and its application in the market

Acrylic sheet according to the production process of casting and extrusion of two major types of sheet.

Acrylic cast sheet

high molecular weight, excellent stiffness, strength and excellent resistance to chemicals. This sheet is characterized by small batch processing, unmatched flexibility in color systems and surface texture effects, and a full range of product specifications for a variety of special applications.

Extruded acrylic sheet

Compared to cast sheet, extruded sheet has a lower molecular weight and slightly weaker mechanical properties. However, this feature is conducive to bending and thermoforming processes, in dealing with the larger size of the plate, is conducive to fast plastic vacuum molding. At the same time, the thickness tolerance of extruded boards is smaller than that of cast boards. Because the extruded plate is a high-volume automated production, color and specifications are inconvenient to adjust, so the diversity of product specifications are somewhat limited.

For many years, thermoforming has been one of the most creative uses of acrylic sheet. With the improvement of processing technology and product variety, performance of the rich and perfect, compared to other traditional advertising signage materials, acrylic processing is easier, safer, more reasonable cost-effective products.

Characteristics and advantages of acrylic panels

Unparalleled outdoor weather resistance

- Transparent panels such as crystal clear

- High surface gloss, smooth and flat

- Complete product range, transparent, translucent, opaline and other colors and a variety of different surface effects

Excellent processing performance; thermoforming? Production of outstanding visual effect of the signboard, logo processing easy, reasonable cost

- Green, waste materials can be completely recycled, easy recycling

- Excellent surface hardness and scratch resistance

- Good chemical resistance, better than most other plastic materials

- Easy to clean, maintenance, to ensure that the sign, light box appearance year-round

Advantages and disadvantages The difference between acrylic sheet and a simple identification method?

Acrylic sheet has advantages and disadvantages, in the current domestic pressure grams on the national plate market, there exists a low price, low quality acrylic sheet - recycled acrylic sheet. This type of sheet, is the use of recycled acrylic trimmings, after thermal degradation to get the regeneration of MMA (methyl methacrylate) monomer, and then by the chemical polymerization reaction comes after. It is necessary to specify that, in foreign countries, acrylic manufacturers to develop a scientific waste recycling program, and invested heavily in waste cracking plant, after a rigorous process, you can get pure MMA monomer, and new synthetic monomers, there is no difference in quality. And now some of the domestic backward technology workshop-style small factories, due to the one-sided pursuit of profits, production conditions are simple, the production of degradation of monomer, purity is not high, made of plate, its quality is often not to be commended.

Pure new material transparent acrylic sheet

Excellent UV resistance, outdoor 10 years without yellowing, will not fade, light loss, not cracking

Transmittance is greater than 92%, the cross-section at the transparent colorless

High surface hardness, comparable to aluminum and brass

Excellent resistance to cracking and chemical resistance

High-quality protective film to provide adequate protection

Back to the material transparent acrylic sheet

UV resistance is very poor, up to six months will be yellowed, sunlight exposure is easy to crack

Transmittance is less than 86%, the cross-section of the yellowing

Low surface hardness, easy to scratch

Easy to crack

Low quality of the protective film, easy to age and deteriorate

Through this simple identification method, you can easily identify the quality of acrylic sheet good and bad, to avoid some of the Unnecessary losses.

Because people do not understand the regeneration of acrylic sheet and its low price, regeneration of acrylic sheet in the domestic market still occupies a lot of space. But it can be predicted that, with the gradual deepening of people's understanding of acrylic materials, the survival of recycled board will be less and less space.

Long-term performance

As with all plastic materials, the impact resistance of acrylic products will weaken as the temperature decreases. High-quality acrylic sheet, usually using high-quality raw materials and unique formula production process, so that it has excellent long-term outdoor performance, in the light box, signage applications, the expected outdoor service life can exceed 10 years.

Acrylic product performance

Weatherability

Acrylic sheet has excellent outdoor weatherability, can be bawled out as the best of all plastic materials. Normal outdoor use conditions, the design, processing of reasonable acrylic sheet signage, after 10 years of use, its mechanical strength will not be reduced, the appearance will not significantly change.

The translucency of the color plate

High-quality acrylic panels are produced in accordance with strict quality standards to ensure that different batches, different panels have the same color. Because the color of the color plate is uniformly distributed along the entire thickness of the plate direction, so the surface of the reverse plate abrasion by the light will have some impact on the appearance of the color.

Most of the translucency of the acrylic color plate will be reduced with the increase in plate thickness, for some signage applications, this effect may have a negative impact - for example, in the same sign at the same time when using different thicknesses of the color plate, there will be a significant color difference. In this case, you can consider the use of certain fixed transmittance color acrylic color plate, although the thickness of the sheet together, but present the same color transmittance.

Acrylic and advertising signs

Whether you want to set up a unified logo in the world of multinational corporations or small stores, factories, offices, there is a need for a durable, eye-catching, unique and relatively economical signage. Acrylic sheet excellent comprehensive performance can fully meet the above requirements, acrylic light box light transmission uniformity and soft and distinct, and therefore not only eye-catching and can save energy; acrylic's own luster makes the acrylic light box signage in the daytime without the lights of the conditions are also exceptionally compelling, but also easy to process, choose the appropriate varieties and processing methods can produce a variety of light boxes or signs. Acrylic light box is durable, outdoor available for more than ten years, installation and maintenance is also very convenient. Acrylic light box signage such as regular cleaning, the method is very simple, with soapy water and soft cloth or brush can be scrubbed, but do not use hard brushes or coarse cloth, such as the need to improve the degree of antistatic light box, sprayed with a special antistatic agent has a significant effect.

You may have noticed that McDonald's restaurants around the world are using color and shape of the acrylic signage; BP chose a unique green and yellow acrylic signage decorated gas stations around the world; the famous department store chain store Marks and Spencer (Marks seek Spencer) using a different transmittance of the acrylic board in the Eurasian region, more than 400 stores mounted on the eye-catching and bright signage.

Wide application of acrylic

acrylic has the advantages of transparent, lightweight, weather-resistant, impact-resistant, easy to mold. Its molding methods are casting, injection molding, machining, thermoforming. Especially injection molding, injection mold, mass production, simple process, low cost. In recent years, under the continuous improvement of machinery and equipment and processing technology, the quality and quantity of acrylic products are increasing, the application range is also becoming more and more extensive, especially advances in science and technology, acrylic has become a liquid crystal display (LCD) of the light-conducting materials.

Properties of Plexiglass Acrylic

[1]?

Highly transparent?

Plexiglass is currently the finest polymer transparent material, light transmission rate of 92%, higher than the transmittance of glass. Called the artificial small sun of the sun lamp lamp is made of quartz, this is because the quartz can completely through the ultraviolet radiation. Ordinary glass can only transmit 0.6% of the ultraviolet light, but Plexiglas can transmit 73%.

High mechanical strength?

The relative molecular mass of plexiglass is about 2 million, is a long chain of polymer compounds, and the formation of molecules in the chain is very soft, so the strength of plexiglass is relatively high, the ability to resist stretching and impact than ordinary glass 7 to 18 times higher. There is a kind of heating and stretching processed plexiglass, in which the molecular chain segments are arranged in a very orderly manner, so that the toughness of the material has a significant improvement. With a nail into this plexiglass, even if the nail penetrates, the plexiglass does not produce cracks. This kind of plexiglass by the bullet will not break into pieces after the same. Therefore, the stretching treatment of plexiglass can be used as bulletproof glass, but also used as a seat cover on military aircraft.

Lightweight?

The density of plexiglass is 1.18--1.19kg/dm3, the same size of the material, its weight is only half of ordinary glass, metal aluminum (belongs to the light metal) 43%.

Easy to process?

Plexiglass can not only be cut with a lathe, drilling machine for drilling, and can be acetone, chloroform, etc. bonded into a variety of shapes of appliances and plexiglass products, but also can be blown, injected, extruded and other plastic molding methods processed into a large aircraft cockpit cover, as small as the dentures and teeth, and other products of all shapes and sizes.

Matters of acrylic crafts

1, ordinary acrylic plate heat distortion temperature of about ?100?degree? The continuous use of the temperature should not be higher than 90 degrees.

2?, acrylic plate surface hardness equivalent to aluminum, in use or processing should be careful to avoid surface scratches. If scratched, you can restore the original glossy surface by polishing.

3?, acrylic panels are prone to static electricity, adsorption of dust. Cleaning with a soft cotton cloth dipped in ?1%? Soap and water can be wiped.

4?, acrylic casting plate has a certain coefficient of expansion, in the installation of acrylic panels must be considered to leave enough room for proper expansion and contraction.

How to avoid the deformation of acrylic products?

1?, the installation framework must be reserved for contraction and expansion gap?

2? Drill elliptical screw holes with screws to lock the frame.

3?, choose the elastic rubber gasket?

4. Thermoforming improves the impact strength and releases internal stresses.

6?, Thermoforming into waves, diamonds and semicircles prevents acrylic panels from sagging and deforming under their own weight?

6?, the use of large-format acrylic sheet, must increase the thickness to prevent the sheet due to the weight of the sagging deformation?

7?, choose the appropriate thickness to avoid bending and deformation of acrylic panels due to wind load

Plexiglass market development prospects

[2] Plexiglass is the development of an important thermoplastic earlier, with transparency, stability and weather resistance, easy to dye, easy to process, beautiful appearance, has a wide range of applications in the construction industry.

In terms of construction, Plexiglas is mainly used in light bodies, roofs, trellises, staircases and interior wall sheathing. In recent years, plexiglass in the highway and advanced road lighting lampshade and automotive lamps and lanterns in the application is also quite fast. With the construction of big city hotels, hotels and high-level residential construction, the rapid development of the light body, the use of plexiglass extruded plate made of light body has a high overall structural strength, light weight, high light transmittance and good safety performance, etc., compared with the inorganic glass lighting fixtures, with a great deal of superiority.

In terms of sanitary ware, plexiglass can be produced bathtubs, washbasins, vanity and other products. As the plexiglass bathtub has a luxurious appearance, a sense of depth, easy to clean, high strength, lightweight and comfortable to use, etc., in recent years has been widely used.

At present, the United States and Japan have made mandatory in the law, primary and secondary schools and kindergarten buildings must use plexiglass. With the continuous improvement of China's laws, is expected in the near future will also make the corresponding provisions. At the same time, China has accelerated the pace of urban construction throughout the country, the use of plexiglass produced by the street signs, advertising light boxes and telephone booths will also appear in large quantities, thus plexiglass has a lot of room for development, the market outlook is very broad.

Can be comparable to the diamond plastic - acrylic
