History of technology development
Acrylic (ACRYLIC), common name special treatment plexiglass sheet. Acrylic research and development, has been a hundred years of history. 1877 acrylic acid polymerization was first discovered; 1880 methacrylic acid polymerization is known; 1901 propylene polypropylene glycol synthesis of the completion of the study; 1927 the use of the aforementioned synthetic method to try to industrial manufacturing; 1937 methyl ester industry Manufacturing and development success, which entered the scale of manufacturing. During World War II due to the excellent strength and transparency of acrylic and light transmission, first, was applied to the aircraft windshield, tank driver cab sight mirror. The birth of the world's first acrylic bath in 1948 marked the entry of a new milestone in the application of acrylic.

Acrylic cast plate: high molecular weight, with excellent stiffness, strength and excellent resistance to chemical properties. This plate is characterized by small batch processing, in the color system and surface texture effects have unparalleled flexibility, and product specifications complete for a variety of special purposes.
Acrylic Extrusion Board: Compared with the cast plate, the extruded plate molecular weight is low, mechanical properties weaker. However, this feature is conducive to bending and thermoforming processing, in dealing with larger size of the plate, is conducive to rapid vacuum plastic molding. At the same time, the thickness tolerance of the extruded plate is smaller than that of the casting plate. As the squeeze plate is a large number of automated production, color and specifications inconvenient to adjust, so the product specifications are subject to certain restrictions.
Acrylic board material classification in the country is divided into three categories: First, the import plate; Second, Taiwan-funded board; Third, The difference between them is the origin of raw materials used and (MMA) purity. This is also the key to determining the quality and price of the plate.
Domestic imports of acrylic board with Japan's Mitsubishi (Japan's Mitsubishi Chemical) and Germany's Degussa two brands.
The so-called Taiwan-funded board refers to the use of British Lucite (MMA) pure raw materials and Taiwan's technology, technology made of sheet metal. Most of the molds used in the production of plates are manufactured in the UK and Germany. Production of the acrylic plate color uniform, no water marks, thin thickness error is small; the market are common: Hua Shuai special, Ruichang, Shen Mei, thousands of colors, Osaki Kam and other brands, including China and Thailand special brand in the market recognition High prices, the market price of 26-28 yuan / kg (its price is with the oil movements and floating); there are some brands such as Tomson, Chuang Asia, Green River, Xin Shun and other brands, are also the so-called Of the Taiwan-funded board, but the use of raw materials is MMA's new material, quality is also good. Market price of 20-24 yuan / kg. After the use of color rhyme on the use of plate machine is quite good.
Domestic plate refers to the production of raw materials used in a plate is made, and the other is a variety of acrylic plate recovery material (PMMA) for the secondary processing generated. But the disadvantage is the surface of water marks obvious, uneven thickness, easy to yellow, not suitable for plastic forming, only for carving. The advantage is low price Experiments on the tablet machine. The effect of spraying and imports have a certain gap.

Acrylic board variety, rich colors, and has a very excellent overall performance, designed for designers to provide a variety of options, acrylic board can be dyed, the surface can be painted, silk screen or vacuum coating
5, non-toxic even if long-term contact with people is also harmless, but the combustion is not complete will produce formaldehyde, carbon monoxide
6, the linear expansion coefficient of the cast plate is about 7x10-5m / m.K.
Acrylic has a "plastic crystal" reputation. And has excellent weather resistance, especially for outdoor, other plastic crown, and both good surface hardness and gloss, processing plasticity, can be made into a variety of shapes and products. Another variety of plate color rich (including translucent palette), another feature is the plate can still maintain high transparency.
Products
Acrylic through a variety of processing technology, can be made into a special decorative, unique decorative effect of the products. Process: composite process, pouring process, hot melt process, laser technology, carving process, injection molding process, extrusion process ...
use
PMMA has the advantages of light weight, low cost, easy molding. Its molding methods are casting, injection molding, machining, thermoforming and so on. Especially the injection molding, can be mass production, the process is simple, low cost. Therefore, it is increasingly widely used, it is widely used in instrumentation parts, car lights, optical lenses, transparent pipes and so on.
Acrylic is the best new material that can produce sanitary ware after the ceramic. Compared with the traditional ceramic materials, acrylic in addition to unparalleled high brightness, but also the following advantages: toughness, easy to damage; repair strong, as long as the soft foam dipped in toothpaste can clean the sanitary ware; soft texture, winter There is no sense of cold biting; colorful, to meet the different quality of the pursuit of personality. Acrylic production of pots, bathtubs, toilet, not only exquisite style, durable, and has an environmental role, the radiation and the body's own bone radiation degree is almost the same. Acrylic sanitary ware first appeared in the United States, has occupied more than 70% of the international market.
As the acrylic production is difficult, high cost, so the market there are many low-cost cheap substitutes. These substitutes are also known as "acrylic", in fact, ordinary organic board or composite board (also known as sandwich board). Ordinary organic board with ordinary plexiglass lacquer plus pigment casting

, The surface hardness is low, easy to fade, polished with fine sand polished effect is poor. Composite panels only a thin layer of acrylic surface, the middle is ABS plastic, the use of thermal expansion and contraction is easy to delamination. True and false acrylic, from the plate section of the subtle color and polishing effect to identify
1. Architectural applications: window, noise doors and windows, light mask, telephone booths and so on
2. Advertising applications: light boxes, signs, signs, exhibition and so on
3. Transportation applications: train, car and other vehicles, doors and windows
4. Medical applications: baby care box, a variety of surgical and medical equipment civilian supplies: bathroom facilities, handicrafts, cosmetics, stents, aquariums, etc.
5. Industrial applications: instrument panel and cover, and so on
6. Lighting applications: fluorescent lamps, chandeliers, street lights and so on
Product advantages
1. Hardness: hardness is the best embodiment of casting acrylic production technology and technology parameters, is an important part of quality control. Hardness can reflect the purity of raw materials MMA, sheet weather resistance and high temperature performance. Hardness directly affect the plate will shrink shrinkage deformation, processing, whether the surface will appear chapped and so on. Hardness is one of the rigid indicators to judge the quality of acrylic board. Imported material cast acrylic board with the current domestic equivalent of the highest hardness indicators. The average Darling hardness is about 89 degrees.
2. Thickness Tolerance: The thickness tolerance here is the thickness of the acrylic sheet of acrylic tolerance, this tolerance control is an important manifestation of quality management and production technology. The thickness of the extruded acrylic plate is controlled within + 0.2 mm.
3. Transparency / whiteness: strict selection of raw materials, advanced recipe follow-up and modern production process to ensure that the plate excellent transparency and pure whiteness. Flame polished after crystal clear.
