Different performance, different colors and visual effects to meet the ever-changing requirements.
1, the acrylic plate according to the production process sub-cast plate and squeeze plate, according to the light can be divided into transparent plate, translucent board (including the transparent plate), color plates (including black and white and color plate) Impact plate, anti-ultraviolet board, ordinary board and special plate such as high impact plate, flame retardant board, matte board, metal effect board, high wear plate, light guide plate and so on.
A: cast plate: high molecular weight, with excellent stiffness, strength and excellent resistance to chemical properties. And thus more suitable for processing large-size identification plaque, relative to the softening process in a little longer. This plate is characterized by small batch processing, in the color system and surface texture effects have unparalleled flexibility, and product specifications complete, practical for a variety of special purposes.
B: Extrusion plate: Compared with the cast plate, the extruder has a low molecular weight, a slightly lower mechanical property and a higher flexibility. However, this feature is conducive to bending and thermoforming processing, softening time is shorter. In dealing with large size of the plate, is conducive to a variety of 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 inconvenience conditioning, so the product specifications diversity subject to certain restrictions.
2, there is a kind of acrylic called back to the recycled plate is the use of recycled acrylic scrap, after thermal degradation to be recycled MMA (methyl methacrylate) monomer, and then by chemical polymerization reaction. After a rigorous process, you can regain the pure MMA monomer, with the new synthetic monomer, there is no difference in quality. But the production of degradation of monomer, the purity is not high, sheet metal forming, its quality, poor performance.
Summary: Extrusion plate using pellet raw materials, after high temperature dissolved after extrusion molding, and casting plate is MMA monomer (liquid) direct casting molding, although the extrusion plate shape is relatively smooth and smooth, but because of its granular material in the molding To complete the aggregation. In the processing of sheet metal when the structure, performance is weak, not suitable for outdoor identification of the product material, only for crystal word or product stent and other indoor products.
In addition, most of the extruded plate does not have anti-ultraviolet function, its outdoor life and casting plate is quite different, the color will fade and easily brittle, until the rupture. Casting plate is in the process of processing the plate to complete the structure of polymerization, during which the addition of UV absorbers, with high strength and UV function, outdoor life of up to 5 years or even 10 years, the use of color has been bright as new.
