Attention Should Be Paid To The Expansion Factor Of The Acrylic Jewelry Display
Jun 19, 2017

Attention should be paid to the expansion factor of the Acrylic Jewelry Display
Acrylic is made of polymethyl methacrylate, polymethyl methacrylate containing polar side methyl, with strong hygroscopic properties, water absorption in the acrylic sheet must always be kept dry, dry conditions required is 78 ℃ -80 Lt; 0 & gt; C for 5-6 h. The range of adaptation of poly (methyl methacrylate) to ambient temperature does not have a common fluidity, but a non-Newtonian fluidity, so that the high solubility of the acrylic will be reduced at high temperatures, which is very sensitive to temperature Performance.
Acrylic in the process of flowing the temperature are generally around 150 ℃, but when the acrylic began to break down when the temperature is higher than 270 ℃, so that the temperature changes are still very flexible, not affected by the temperature Production, high temperature is the characteristics of acrylic.
Acrylic also has a good cutting performance, can be measured in the case of a good size by laser cutting processing, simple high quality, this feature is not available in the glass, so the acrylic can withstand high temperature and low temperature of the environment, consumers in the production The process do not have to worry about the temperature problem.
Acrylic is an invisible polymer, its shrinkage range is reduced, are generally in the 0.45% -0.9, so the acrylic production when the molding accuracy provides a very good condition, under normal circumstances are very accurate molding of.
Acrylic with high transparency, light transmission rate of 92%, "plastic crystal" reputation. And has excellent weather resistance, especially for outdoor, other plastic crown, and both good surface hardness and gloss, processing plasticity, can be made into a variety of shapes and products. Another wide variety of plate color rich (including translucent palette), another feature is the plate can still maintain high transparency.
Acrylic Jewelry Display stand should pay attention to the four common sense
First, the ordinary acrylic plate thermal deformation stability of about 100 degrees, so the use of Acrylic Jewelry Display stand when the temperature should pay attention to this value, such as in the continuous use of the temperature should not be higher than 90 degrees.
Second, the Acrylic Jewelry Display frame surface hardness is equivalent to aluminum, so in the use or acrylic processing should be careful to avoid the surface was scratched. If it is scratched by polishing to restore the original glossy surface.
Third, in a slight scratch or due to static electricity generated by the adsorption of dust caused by the Acrylic Jewelry Display stand fuzzy or unclean can be dipped in 1% soap and water in the soft cloth with the wipe it can be wiped clean.
Fourth, this is in the Acrylic Jewelry Display rack assembly process need to pay attention to the details, because the acrylic sheet has a certain coefficient of expansion, so when the installation must take into account the acrylic plate thermal expansion and contraction factors, in the assembly time To have a telescopic space gap.
