Discrimination:
1. hand: acrylic material quality silky feel mellow, and without stains, fingerprints.
2. thickness: the thickness is the hard standard of the acrylic bearing range, and the 6~12 millimeter is the common thickness.
3. uniformity: whether or not the color is uniform is also one of the criteria for judging whether or not the acrylic is good or bad.
4. Hardware: the hardware with good quality and beautiful appearance is very important for transparent furniture. Inferior hardware easily in long time caused by the use of abstruse and rust, flexible etc.. How to identify the acrylic plate
At present, a new type of acrylic bathtub has been developed in China, which has gradually been recognized by consumers. But there are three kinds of acrylic plates in the domestic market: the acrylic board for sanitary ware, the ordinary acrylic board and the ABS acrylic composite board. The latter two kinds of plates have some defects because of their material. In fact, they are not suitable for making bathtubs and bathtubs.
Acryl chemical name methyl methacrylate, that is, "organic glass". The special acrylic plate for sanitary ware has excellent surface finish, its wear resistance is equivalent to aluminum, it is not easy to wipe hair and easy to clean. If a surface accidental scratch occurs, the removal can be quickly and convenient as long as the polishing agent is used. The plate itself has a certain elasticity, even if the surface is subjected to a certain impact, it is not easy to open.560

3. the temperature of polymethyl methacrylate began to flow at about 160 degrees C, and the decomposition temperature was higher than 270 degrees C, with a wider range of processing temperature.
4., polymethyl methacrylate melt has higher viscosity and faster cooling rate, and products are prone to produce internal stress. Therefore, molding process requires strict control of process conditions, and post processing is also needed after products are molded.
5., polymethyl methacrylate is amorphous polymer. Its shrinkage and its range of variation are relatively small. Generally, it is about 0.5%-0.8%, which helps to form high precision plastic parts.
6. good cutting performance of PMMA, the profile can be easily machined to the required size. Molding key


Polymethyl methacrylate can be used in casting, injection molding, extrusion and thermoforming.
casting molding
The casting is used to shape the material of the organic glass sheet and rod, that is, the shape of the material is formed by the method of bulk polymerization. After casting, the products need to be treated after treatment. The post treatment conditions are 2H at 60 C and 2H at 120.
injection molding累计金额(美元)
The injection molding is made of particles made by suspension polymerization, which is formed on a common plunger type or screw type injection molding machine. Table 1 is a typical process condition for the injection molding of polymethyl methacrylate.

The rear part of the barrel temperature is 180-200 180-200
Central 190-230
The front 180-210 210-240
The temperature of the nozzle is 180-210 210-240

Injection products also need post-processing to eliminate internal stress. The treatment is carried out in a hot air drying box at 70-80 degrees. The thickness of processed products is generally 4H.
