What is acrylic?
Acrylic fiber is an important thermoplastic with early development, which is transparent, weatherproof, stable, easy to process, easy to dye and beautiful in appearance. It is widely used in the construction industry and is a common substitute for glass.
In the construction industry, acrylic is mainly used for lighting, stairs, roofs, shed roofs and indoor wall protection. In recent years, acrylic has been widely used in road lighting lampshades and automobile lamps.
With the construction of hotels, guesthouses and high-grade houses in big cities, the lamp body has developed rapidly. The lamp body made of acrylic has the characteristics of high overall structural strength, light weight, strong light transmittance and high safety performance, which has great advantages compared with ordinary glass lighting devices.
In sanitary ware, acrylic can make bathtub, dresser, washbasin and other products. Because the acrylic bathtub has the characteristics of luxurious appearance, easy cleaning, depth, light weight, high strength and comfortable use,
It has been widely used in recent years. Advantages and disadvantages of acrylic materials
Advantages:
Acrylic is the best new material for making sanitary ware after ceramics. Compared with traditional ceramic materials, acrylic not only has unparalleled high brightness,
It also has the following advantages: good toughness and not easy to break; Strong recovery, as long as you dip in soft foam toothpaste, you can wipe the sanitary ware; Soft texture, no icy feeling in winter; Bright colors can satisfy the individual pursuit of different tastes. The basin, bathtub and toilet made of acrylic are not only exquisite and durable, but also environmentally friendly, and their radiation level is almost the same as that of human bones. Acrylic bathroom first appeared in the United States and has occupied more than 70% of the entire international market. Disadvantages:
Due to the difficulty and high cost of acrylic production, there are many low-quality and low-cost substitutes on the market. These substitutes, also called "acrylic", are actually ordinary organic boards or composite boards (also called sandwich boards). Ordinary plexiglass plate is cast with ordinary plexiglass cracking material and pigment, which has low surface hardness and is easy to fade, and the polishing effect is poor after polishing with fine sand. The composite board has only a thin layer of acrylic with ABS plastic in the middle, which is easy to be layered due to thermal expansion and cold contraction in use. True and false acrylic can be identified from the subtle color difference and polishing effect of the plate section.
Classification of acrylic board
Acrylic casting plate: high molecular weight, excellent rigidity, strength and excellent chemical resistance. This kind of plate is characterized by small batch processing, unparalleled flexibility in color system and surface texture effect, complete product specifications and suitable for various special purposes.
Acrylic extruded board: Compared with cast board, extruded board has lower molecular weight and slightly weaker mechanical properties. However, this feature is beneficial to bending and thermoforming, and is beneficial to rapid vacuum suction forming when dealing with large-size plates.
At the same time, the thickness tolerance of extruded plate is less than that of cast plate. Because the extruded board is produced automatically in large quantities, the color and specifications are not convenient to adjust, so the diversity of product specifications is limited to some extent. The material classification of acrylic board is mainly divided into three categories in China: first, imported board; The second is Taiwan-funded board; The third is the domestic board. 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 the plate.
