Understand acrylic sheets laminates
Guide: Acrylic, also known as specially treated plexiglass, is a replacement product of plexiglass. The light box made of acrylic has the characteristics of good light transmission, pure color, rich color, beautiful and smooth appearance, giving consideration to both day and night effects, long service life, and no impact on use. In addition, acrylic panels can be perfectly combined with aluminum plastic panel profiles and advanced screen printing to meet the needs of businesses. Acrylic plastic is the best outdoor advertising form to improve the level of business stores and unify the corporate image.
“Acrylic” is a transliteration word, ACRYLIC in English. It is a chemical material. The chemical name “PMMA” belongs to polyacrylate, commonly known as “specially treated organic glass”. The raw materials of acrylic in the application industry are generally in the form of particles, sheets laminates s, pipes, etc. Acrylic is transliterated from English Acrylic, which is the general name of acrylic acid and methacrylic acid chemicals. It includes monomers, sheets laminates s, granules, resins and composites. Acrylic sheets laminates s are polymerized from methyl methacrylate monomer (MMA), namely polymethyl methacrylate (PMMA) sheets laminates organic glass. The “organic glass” comes from the trade name “Organic” (a kind of PMMA sheets laminates ) and is taken from “Organic Glass” (i.e. organic glass). The polymerization of acrylic acid was discovered in 1872; In 1880, the polymerization of methacrylic acid was known; In 1901, the research on the synthesis method of propylene polypropionate was completed; In 1927, the above-mentioned synthesis method was used to try industrial manufacturing; In 1937, the methyl ester was successfully manufactured and developed in industry, which led to large-scale manufacturing. During World War II, because of its excellent strength, toughness and light transmittance, acrylic was first applied to the windshield of aircraft and the sight glass of tank driver’s cab. The birth of the first acrylic bathtub in the world in 1948 marked a new milestone in the application of acrylic. The understanding classification can be divided into acrylic casting sheets laminates , acrylic extrusion sheets laminates and acrylic sheets laminates material classification. Acrylic casting sheets laminates : high molecular weight, excellent stiffness, strength and excellent chemical resistance. This kind of board is characterized by small batch processing, incomparable flexibility in color system and surface texture effect, and complete product specifications, suitable for various special purposes. Acrylic extrusion sheets laminates : compared with the casting sheets laminates , the molecular weight of the extrusion sheets laminates is lower and the mechanical properties are slightly weak. However, this feature is conducive to bending and hot forming, and it is conducive to rapid vacuum plastic forming when processing large size sheets laminates s. At the same time, the thickness tolerance of the extrusion sheets laminates is smaller than that of the casting sheets laminates . Due to the large batch automatic production of extruded boards, the color and specification are inconvenient to adjust, so the diversity of product specifications is limited. The material classification of acrylic sheets laminates s is mainly divided into three categories in China: first, imported sheets laminates s; Second, the Taiwan Capital Board; Third, domestic boards. The difference between them lies in the origin and (MMA) purity of the raw materials used. This is also the key to determine the quality and price of sheets laminates s. Features Good weather resistance and acid and alkali resistance, no yellowing and hydrolysis due to years of sun and rain; Long service life, more than three years longer than other material products; Good light transmission, up to 92%, light intensity required is small, saving electricity; Strong impact resistance, 16 times of ordinary glass, suitable for installation in areas where safety is particularly needed; Excellent insulation performance, suitable for various electrical equipment; Light weight, half lighter than ordinary glass, and the load borne by buildings and supports is small; Bright colors and high brightness are incomparable with other materials; Strong plasticity, large change in modeling, easy processing and molding; The high recycling rate is recognized by the increasing awareness of environmental protection; It is easy to maintain and clean. The rain can be cleaned naturally, or it can be wiped with soap and soft cloth. Advantages: 1. Excellent transparency Acrylic sheets laminates , colorless transparent organic glass sheets laminates , with a light transmittance of more than 92% 2. Excellent weather resistance, strong adaptability to the natural environment, will not change its performance even if it is exposed to sunlight, wind and rain for a long time. It has good aging resistance, and can be used safely outside the room 3. Good processing performance, which is both suitable for mechanical processing and easy to be hot formed 4. There are many kinds of excellent comprehensive performance acrylic sheets laminates s It is rich in color and has extremely excellent comprehensive performance, providing designers with a variety of choices. Acrylic sheets laminates s can be dyed, and the surface can be painted, silk screen or vacuum coated. 5. It is non-toxic and harmless even in long-term contact with people, but it will produce formaldehyde when the combustion is incomplete. 6. The linear expansion coefficient of cast sheets laminates s is about 7×10-5m/m K。 Use 1. Building application: shop windows, sound insulation doors and windows, light shields, telephone booths, etc. 2. Advertising application: light boxes, signboards, signs, exhibition racks, etc. 3. Transportation application: doors and windows of trains, automobiles, etc. 4. Medical application: baby care boxes, various surgical and medical appliances and civilian articles: sanitary facilities, handicrafts, cosmetics, brackets, aquariums, etc. 5. Industrial application: instrument surface panels and covers, etc. 6. Lighting application: fluorescent lamps, chandeliers Street lamp cover and other precautions 1. Acrylic sheets laminates shall not be stored in the same place with other organic solvents, let alone contact with organic solvents. 2. During transportation, the surface protective film or protective paper shall not be scratched. 3. It shall not be used in an environment where the temperature exceeds 85 ℃. 4. When cleaning acrylic sheets laminates , only 1% fat soapy water shall be used, and soft cotton cloth shall be dipped in soapy water, and hard objects or dry wiping shall not be used, otherwise the surface will be easily scratched. 5. Acrylic sheets laminates has a large cold and hot expansion coefficient, Due to temperature changes, expansion clearance should be reserved.
