Acrylic is a very common material in people's daily lives. This material has been born has been widely used in the production field, from the outdoor light box, signboards to indoor fluorescent lamps, screens and so on. So what is acrylic? Here is a detailed introduction.
First, what is the material acrylic
Acrylic is the English translation of the English "ACRYLIC", that is, Plexiglas, acrylic is a development of an earlier thermoplastic plastic, with good transparency, stability, beautiful appearance, easy to process, in the building materials, has a wide range of applications. has a wide range of applications.
And we see in our daily life, heard the acrylic fiber, acrylic cotton, acrylic yarn, etc., these are polymerized by the chemical substances from the man-made fibers, and acrylic products are not related.
Second, the use of
Acrylic, also known as PMMA, polymethyl methacrylate, so far the most excellent quality of synthetic transparent materials. Acrylic has a lightweight, inexpensive, easy to mold, simple process, low cost, therefore, it is gradually being widely used, not only in construction materials, but also widely used in instrumentation parts, automotive lamps, optical lenses and so on.
1. Building materials: windows, soundproof doors and windows, light covers, telephone booths, fluorescent lamps, chandeliers, sanitary facilities, integrated ceiling, partitions, screens, etc.
2. Advertising facilities: light boxes, signboards, signage, display racks, etc.
3. Transportation facilities: trains, automobiles, taxis, and other vehicles, such as doors and windows, etc.
4. Medical equipment: infant care boxes, A variety of surgical medical instruments, etc.
5. Industrial equipment: instrument surface plate, cover, etc.
Third, the main classifications
1. Acrylic sheet according to the production process of casting and extrusion plate, according to the transmittance can be divided into transparent plate, translucent plate (including dyeing plate transparent plate), color plate (including black and white and color plate); according to the performance of the impact plate, UV plate, ordinary plate and special plates such as high impact plate, high impact plate, UV plate, UV plate, UV plate, UV plate, and so on. Special boards such as high impact boards, flame retardant boards, frosted boards, metal effect boards, high wear-resistant boards, light guide boards and so on.
2. Acrylic is also called a recycled sheet recycled acrylic trimmings, after thermal degradation to get the regeneration of MMA (methyl methacrylate) monomer, and then by the chemical polymerization reaction came after.
After a rigorous process, you can get pure MMA monomer, and new synthetic monomer, there is no difference in quality. However, the production of degraded monomer, the purity is not high, after the plate molding, its quality and performance is very poor.Extruded plate using granular raw materials, after high-temperature dissolution of extrusion molding, while the casting plate is with MMA monomer (liquid) direct casting molding, although the extruded plate appearance is more flat and smooth, but because of its granular raw material molding in order to complete the polymerization. In the processing of the plate when its structure, performance is weak, and is not suitable for outdoor signage products as materials, only suitable for crystal word or product support indoor products.
Acrylic from the production process can be divided into several main casting plate and extrusion plate. There are some manufacturers through the recycling of acrylic material reprocessing, the production of the explanation of the monomer, although the cost is very low but the performance of such materials is very poor, easy to damage.
