In terms of sanitary ware, due to the plexiglass acrylic bathtub has a luxurious appearance, a sense of depth, easy to clean, high strength, light weight and comfortable to use, etc., in recent years, has been widely used, the current domestic annual output of plexiglass acrylic bathtubs of about 1.5 million, the annual consumption of more than 5,000 tons of PMMA extruded plate or casting plate.
With China's building regulations are increasingly improved, PMMA will certainly be in more applications to show strong competitiveness.
In addition, special plexiglass, such as optical plexiglass, ray-resistant plexiglass and CD-ROM-level plexiglass in China's construction applications are still blank, there is more room for development.
2. China's plexiglass acrylic (acrylic) PMMA production and market situation in China's current total production capacity of plexiglass products in the daily output of about 130,000 tons, there are many manufacturers, but the production scale is small.
Domestic plexiglass acrylic production and processing capacity is very large, but the product structure is not very reasonable, only the production of ordinary varieties of products, the lack of high value-added products needed in the construction industry, in terms of variety and quality can not meet market demand, such as construction of extruded panels with a high demand for a large number of imports from abroad.
In recent years, China's plexiglass acrylic (acrylic) consumption is growing rapidly, but due to China's plexiglass PMMA product varieties monotonous, fewer, poorer quality, far from meeting the needs of the domestic market, resulting in a substantial increase in imports year by year. 2000 China's imports of PMMA molded plastic amounted to 77,000 tons, while also importing plexiglass sheet nearly 4000 tons. From the point of view of the import area, Guangdong, Shanghai, Zhejiang and Jiangsu, four provinces and cities combined imports accounted for about 95% of the country's total imports. Jiangsu, Shanghai is the main production area of China's plexiglass casting plate, due to the model casting process is simple, less investment, so many township and village enterprises with this process for workshop production, small-scale devices, product quality is far less than the quality standards of the building materials industry, has long been eliminated in foreign countries.
The 1980s, China's acrylic (acrylic) Plexiglas annual sales of less than 20,000 tons, the consumer market is not mainly in the construction industry. Into the 1990s, PMMA market applications in the construction industry has been a large development, consumption has grown rapidly, in 2000 has reached 85,000 tons, of which 29,000 tons of casting plate, 25,000 tons of extruded plate, molded plastic 31,000 tons (excluding extruded plate with molded plastic). It is expected that in the next few years, the domestic acrylic plexiglass market development rate will remain at an average annual rate of more than 6%. Expected in 2005, China's acrylic plexiglass market capacity of 110,000 tons, of which the construction industry accounted for about 60% to 70%
Early in the 1920s, Rohmenhausen first invented the polymerization of MMA into acrylic panels (acrylic panels) method, this sheet is called "ologlas/plexiglas". However, the company failed to find a more economical production of MMA process route, and thus acrylic sheet (acrylic sheet) was not popularized.
In 1931, ICI scientists invented the production of MMA acetone cyanohydrin method, which greatly reduced the cost of MMA, so that the acrylic sheet (acrylic sheet) can be popularized. At the same time, ICI also successfully developed acrylic sheet (acrylic sheet) for use in areas such as the cockpit canopy of fighter jets, and then ICI built the world's largest acrylic sheet factory in the United Kingdom.
Acrylic sheet and plexiglass
Plexiglass is derived from the trade name "oroglas", meaning "organic glass". As mentioned earlier, oroglas is actually a PMMA sheet, that is, acrylic sheet. Some people think that transparent plastic is organic glass, in order to avoid confusion and misunderstanding, most of the PMMA sheet is now called acrylic sheet, and a variety of PMMA materials generally known as acrylic.
Types of plexiglass acrylic
Acrylic sheet (acrylic sheet): according to the polymerization process is divided into cast sheet (cast sheet) and extruded sheet (extruded sheet), of which the casting of the plate of high molecular weight, more rigid, crack-resistant, and thus is more suitable for the processing of large-size signage. In addition, the cast sheet process is more suitable for the production of small quantities of different colors. Extrusion plate molecular weight is lower, high flexibility, suitable for vacuum molding, extrusion process can better control the thickness of the plate, the production of large quantities of single-color plate is more economical.
Acrylic sheet (acrylic sheet) according to the transmittance and can be divided into pure transparent sheet, color transparent sheet, semi-transparent plate (such as color plate); according to the surface luster, can be divided into high-gloss sheet, mercerized sheet and matte plate (also known as frosted sheet); according to the performance of the acrylic sheet can be his ordinary plate, impact plate, ultraviolet-resistant plate, negative combustion plate and high abrasion-resistant plate, and so on.
Organic glass acrylic characteristics
Organic glass: crystal transparency, transmittance of 92% or more, with the dye coloring of acrylic (acrylic) and has a very good color effect, in addition, acrylic (acrylic) has excellent weather resistance, high surface hardness and surface luster, as well as good high temperature performance. Acrylic sheet has good processing properties, both thermoforming (including molding, blow molding and vacuum vacuum molding), can also be used in mechanical processing which drilling, turning, cutting, etc.. With microcomputer-controlled mechanical cutting and engraving not only make the processing accuracy greatly improved, but also can produce the traditional way can not be completed patterns and shapes. In addition, the acrylic sheet can be laser cutting and laser engraving, the production of products with strange effects.
Transparent acrylic sheet has a comparable transparent light rate with glass, but only half the density of glass. In addition, it is not as fragile as glass, even if the destruction, will not form sharp fragments like glass. Acrylic sheet wear resistance and aluminum close, it is not regularly resistant to a variety of chemical corrosion. Acrylic sheet has good printability and sprayability, the use of appropriate printing (such as screen printing) and spraying process, you can give the acrylic products (acrylic products) ideal surface decorative effect.
After special modification of the acrylic sheet can absorb a large amount of ultraviolet light, in addition to the negative combustion acrylic (acrylic) can still help to overcome the fire hazards of a particular place, high-impact acrylic impact strength is 6 to 10 times the acrylic, the surface has been specially treated with ultra-wear-resistant acrylic sheet can withstand the extremely harsh test.
Acrylic sheet of the above I make it in the aviation, automotive, electronics, medical, chemical, building materials, sanitary ware and advertising signs and other industries have been widely used in the manufacture of a variety of: acrylic products, Plexiglas display (such as: cosmetics display, cell phone display, watch display, glasses display), badges, gift boxes, display racks, signs, signage, acrylic Keychain, jewelry box, jewelry box, colorful chassis, transparent chassis, acrylic light box, furniture accessories, agent sign, acrylic water cluster box, acrylic fish tanks, bathtubs, plexiglass crafts, acrylic medals, various plexiglass products, acrylic handicrafts, pressed Keli cosmetic case.
Plexiglass acrylic (acrylic) plate and advertising signs
Whether you want to set up a sign in the world of multinational corporations or small stores, factories, offices, all need a durable, eye-catching, unique and relatively economical signage. Plexiglass acrylic (acrylic) sheet's excellent comprehensive performance can fully meet the above requirements, acrylic light box light transmission uniformity and soft and distinct, so not only eye-catching, but also can save energy. Acrylic's own luster makes acrylic light box signage in the daytime without the light conditions are also particularly eye-catching, but also easy to process, choose the appropriate varieties of processing methods to produce a variety of light boxes or signs. Acrylic light box is durable, outdoor can be guaranteed for more than ten years, installation, repair and maintenance is also very convenient. Acrylic light box signage cleaning method is very simple: with soap and soft cloth can be scrubbed. But do not use a coarse cloth or hard bristle brush, which is damaging to the plexiglass.
You may have noticed, McDonald's restaurants around the world with color and shape of the unified plexiglass acrylic signage.BP also choose to use plexiglass material to do the sign. The famous department store side of the lock store Marks and Spencer also used different transmittance of acrylic plexiglass panels in more than 400 stores around the world on the installation of eye-catching signage.
Transparent chassis, colorful chassis introduction
Transparent chassis, colorful chassis materials. Whether it is colorful chassis, transparent chassis, the material is plexiglass sheet, that is, acrylic sheet. Do this kind of chassis plate commonly used plexiglass plate, blue plexiglass plate, yellow plexiglass plate and so on.
Colorful chassis, transparent chassis use. Whether it is a transparent chassis, colorful chassis, in fact, are a kind of computer chassis, used for computer assembly. It is just that the materials used in this kind of chassis are different from the traditional chassis.
Two issues affecting the development of colorful chassis, transparent chassis: First, the price. The price of this chassis is currently high compared to traditional computer chassis. The actual cost of this chassis is indeed higher than those traditional computer chassis, this is no way. If you want to have fun with the beautiful effect of the chassis turn up colorful and eye-catching, that can only spend more money. Of course, some merchants are currently overhyped. As for the current market rumors have some ultra-low price colorful transparent chassis, this kind of chassis is actually not a real colorful transparent chassis. It is in the traditional computer chassis plus one or two transparent plate to, not all transparent, the price is of course much lower.
Another problem is heat dissipation. Said above, colorful chassis, transparent chassis materials are plexiglass acrylic sheet. Plexiglass is actually a kind of plastic, heat dissipation is not very good. But it is not that there is no solution. Our current solution is to open a few more vent holes in the chassis, add a few more exhaust fans. From the actual effect, the heat dissipation effect is still good, so please rest assured that customers.
What are the advantages of acrylic bathtub?
The official name of acrylic bathtub is fiberglass reinforced plastic bathtub (acrylic is the harmonic of English ACRYLIC). Its surface material is methyl propyl methyl ester, the reverse side covered with glass fiber, coated with a special resin to enhance. The entire bathtub should be uniform color, smooth surface, no delamination, bubbles, etc.. The thickness of the surface layer is generally more than 3 mm, and the glass fiber and the combination of solid, no peeling.
The acrylic bathtub heat transfer is slow, so good heat preservation, contact with the body surface without "cold" feeling. Compared with cast iron or steel bathtub, there is a more "warm, soft" feeling, will not touch the body. Because of the acrylic reprocessing performance is better, so the manufacture of luxury massage bathtub is not it.
Acrylic bathtub in the installation of the bottom should be full of sand and cement paste, can not be vacated or only rely on a few support points, so as to avoid breakage. Use should prevent sharp and hard objects bumping friction, cleaning should be soft cloth and cleaner light wipe, avoid using a hundred cloth. Once found to have rubbed hair, wipe with a soft cloth plus toothpaste, can restore the luster.
Transparent furniture has been the existence of non-mainstream way to love the avant-garde petites provide a variety of personalized options. However, last year, several incidents of glass furniture cracking, so that people on the transparent furniture, although the heart of the desire but still have palpitations. "Fragile" has become synonymous with transparent furniture, how can we rest assured that the transparent? Look at the recent market quietly sold up alternative transparent material furniture is how hard to us!
Acrylic is a by-product of deep-sea oil refining. In fact, a careful understanding of this material, acrylic will find that it is not so magical, it is also a kind of plexiglass, common transparent cell phone display rack is made of it.
While it is also a kind of glass, but acrylic is not as "fragile" as glass, impact resistance is 200 times stronger than ordinary glass, almost will not break. Its load-bearing changes with the thickness, the thicker the stronger. Reporters in the course of the interview found an acrylic dining table transparent extremely thorough, a change in the usual glass furniture in the support points to choose stainless steel and other load-bearing materials, from head to toe using all acrylic, visible in its ability to withstand unusual. Acrylic has a hard side, but also has the characteristics of flexibility, it is very suitable for modeling, curved corners and curves can be achieved through technology. Its thermal insulation performance is also better than glass, unlike glass "cold in the end", but this also leads to its ability to dissipate heat is relatively poor. This material is the most afraid of sharp objects scratches, but this kind of scratch is also very easy to repair, ordinary white toothpaste can be wiped.
Identification:
1. Feel: high-quality acrylic feel smooth and round, and does not bring sweat, fingerprints prints.
2. Thickness: thickness is the acrylic load-bearing range of hard standards, 8 to 12 centimeters is a common thickness.
3. Uniformity: whether the color is uniform is also one of the criteria for determining whether acrylic is good or bad.
4. Hardware: good quality and beautiful appearance of the hardware for transparent furniture is critical. Poor quality hardware is easy to use for a long time in the cause of hard, rust, inflexible and other problems.
How to identify the sanitary ware acrylic plate
Nowadays, the domestic fashion a new type of acrylic bathtub, has been gradually recognized by consumers. But the domestic market has three kinds of acrylic sheet: sanitary ware special acrylic sheet, ordinary acrylic sheet and ABS acrylic composite plate. The latter two sheets because of its material itself has certain defects, in fact, is not suitable for manufacturing bathtubs, tubs and other sanitary ware.
Acrylic chemical name methyl methacrylate, that is, "Plexiglas". Special acrylic sheet for sanitary ware due to excellent surface finish, its wear resistance is equivalent to aluminum, not easy to rub hair, easy to keep clean. If accidental surface abrasion occurs, only the use of polishing agent, can be quickly and easily trimmed to remove. And then because the sheet itself has a certain degree of elasticity, even if the surface is subject to a certain impact is not easy to crack, broken. In addition, sanitary ware special acrylic sheet also has strong corrosion resistance and light transmission, and because the pigment can be dissolved into the sheet, and therefore its color is very stable, long-term sunshine and rain is not easy to fade. Therefore, in addition to being used for indoor and outdoor decoration, acrylic sheets for sanitary ware are also widely used in other industries.
Ordinary acrylic sheet due to its low hardness, poor heat resistance, low elongation, so easy to crack, easy to break, easy to deformation, and the color is not stable, in the process of use is prone to hair phenomenon. The molding of the bathtub is generally due to the bottom of the larger stretch, it is easy to color changes can usually be seen at the bottom of the corner of the "white", "yellow" and other discoloration phenomena.
ABS acrylic composite panel is made of ABS plate bonded acrylic composite panel on both sides. Thus, it is easy in the sanitary ware flap Cutting place (i.e., the edge) observed. As ABS acrylic composite panel is two different materials bonded together, resulting in inconsistent shrinkage, long-term hot and cold changes, it is easy to produce delamination phenomenon. Again, because the surface of the ABS plate is only a few millimeters thick acrylic, so its stability and abrasion resistance are poor, molding is also easy to produce "white" or other discoloration.
The acrylic pom poms are perfect for festive products, gifts, hair accessories, handicrafts, ready-to-wear hats accessories and material packages, with a variety of colors to choose from. Acrylic pom poms have passed the European safety standard (EN71Part3), very suitable for export.
