Adaptability material plexiglass products on the environment
Acrylic products on the environment, climate adaptation are mainly the following points:
First, the acrylic is made of polymethyl methacrylate, polymethyl methacrylate containing a polar side group, has strong moisture absorption, water absorption is generally about 0.30% -0.42%, acrylic sheet must be kept dry, dried needed is dried at 79 ℃ -87 ℃ 5-6h. Thus the need to prevent moisture from entering the acrylic sheet.
II. Made of poly (methyl methacrylate) adapt to the ambient temperature range does not have ordinary fluidly. Instead of having a non-Newtonian fluid, so in the case of high temperatures, acrylic solvent viscosity will be reduced. This is a very temperature-sensitive acrylic performance. But he does have a strong mobility, acrylic sheet has diversified production.
III. Acrylic temperature in flowing process generally around 150 ℃, but when the acrylic begins to decompose when the temperature is higher than 270 ℃, so that aspect of the change in temperature is still very flexible. Not because of cold and heat and make a huge difference.
IV. Acrylic is an invisible polymer shrink its range are reduced, usually at 0.45% -0.9 &, so the time for the production of precision molding of acrylic provides very good condition. Typically molding are very precise.
