Introduction of Plexiglass
Plexiglass is polymerized by methyl methacrylate monomer (MMA), that is, polymethylmethacrylate (PMMA) sheet plexiglass. “Plexiglass” comes from the trade name “orglas” (a kind of PMMA board) and “organic glass”.But in recent years, all transparent plastics such as PS, PC are collectively referred to as plexiglass.
Acrylic – physical properties
Density: 1.19kg/dm3 light transmittance: 99% impact strength ≥ 16KG / cm3 tensile strength ≥ 61kg / m3 thermal transformation temperature ≥ 78 ℃ thermal softening temperature ≥ 105 ℃.
What kind of adhesive does acrylic use?Acrylic bonding method to different needs, if not high requirements can use 502, but high requirements have to use chloroform (chloroform).Of course, these are not necessarily the best, acetone is also needed, but it is best to mix several formulations.Large scale process products also have special requirements for the adhesive: such as transparency, dryness and solidity. In case of special requirements, special glue for plexiglass made of at least five kinds of raw materials should be used.
Characteristics of organic glass
1. Excellent transparency
Colorless transparent plexiglass plate, light transmittance of more than 92%
2. Excellent weather resistance
Strong adaptability to natural environment, even long time exposure to sunlight and wind and rain will not change its performance, and it has good anti-aging performance and can also be used safely outside.
3. Good processing performance
It is not only suitable for machining, but also easy for hot forming. Acrylic board can be dyed, and the surface can be painted, silk screen printed or vacuum coated
4. Excellent comprehensive performance
Acrylic board has many varieties, rich colors and excellent comprehensive performance, which provides designers with a variety of choices. Acrylic board can be dyed, and its surface can be painted, silk screen printed or vacuum coated
5. Nontoxic, even if long-term contact with people is harmless, and the gas generated during combustion does not produce toxic gas
Specification and thickness
Specification: 1.22 * 2.44m, 1.22 * 1.83M, 1.25 * 2.5m, 2 * 3M, 2.05 * 3.05M
Hardness is one of the most important parameters to reflect the production process and technology of casting acrylic plate, and it is an important part of quality control.The hardness can reflect the purity of raw material MMA, the weatherability and high temperature resistance of the board.Hardness directly affects whether the sheet will shrink, bend and deform, and whether the surface will crack during processing.Hardness is one of the hard indexes to judge the quality of acrylic board.
2. Thickness tolerance:
The control of plate thickness tolerance is an important embodiment of quality management and production technology.The thickness tolerance of imported casting acrylic plate is controlled within + 0.2mm.
3. Transparency / Whiteness:
Strict raw material selection, advanced formula follow-up and modern production process ensure excellent transparency and pure whiteness of the plate.It is crystal clear after flame polishing.
Processing and application of plexiglass
Plexiglass has the advantages of transparency, light weight, weather resistance, impact resistance and easy molding.Its molding methods include casting, injection molding, machining, thermoforming and so on.In particular, the injection molding can be produced in large quantities through the injection mold, and the manufacturing process is simple and the cost is low.In recent years, with the continuous improvement of machine equipment and processing technology, the quality and quantity of plexiglass products are increasing, and the scope of application is becoming more and more extensive, especially with the progress of science and technology, plexiglass has become the light guide material of liquid crystal display (LCD).Plexiglass is widely used in various industries and is closely related to our life

Application of plexiglass
Plexiglass has the advantages of light weight, low price and easy molding.Its molding methods include casting, injection molding, machining, thermoforming, etc.In particular, injection molding can be mass produced with simple process and low cost.Therefore, it is widely used in instrument parts, automobile lamps, optical lenses, transparent pipes and so on.
Acrylic is the best new material to make sanitary ware after ceramics.Compared with traditional ceramic materials, acrylic has the following advantages besides its incomparable high brightness: good toughness, not easy to damage;Strong restorative, as long as the soft foam dipped in toothpaste can wipe the sanitary ware a new.Soft texture, no cold and piercing feeling in winter;Colorful, can meet the personality pursuit of different taste.Using acrylic to make basin, bathtub and toilet is not only exquisite in style and durable, but also has the function of environmental protection. Its radiation line is almost the same as that of human body's own bone.Acrylic sanitary ware first appeared in the United States and now accounts for more than 70% of the international market.
Due to the difficulty and high cost of acrylic production, there are many low-cost substitutes in the market.These substitutes, also known as “acrylic”, are actually ordinary organic boards or composite boards (also known as sandwich boards).Ordinary organic board is cast with ordinary organic glass cracking material and pigment. The surface hardness is low, easy to fade, and the polishing effect is poor after grinding with fine sand.The composite board only has a very thin layer of acrylic on the surface, and ABS plastic in the middle. It is easy to delamination due to thermal expansion and cold shrinkage in use.The true and false acrylic can be identified from the slight color difference and polishing effect of the plate section
