Pay more attention to the usage of
Temperature: Acrylic sheets are softened with heating at 100 Centigrade or over. To prevent from becoming soft, please keep units beyond the place over 100 Centigrade.
Scratch: The hardness of surface is equivalent to aluminum, thus be careful to surface protection during process.
If there are scratches on the surface of acrylic sheets, polish them with cleaner used for brass that can remove its brilliant surface.
Cleaning: Due to acrylic sheet with static electricity, clean the surface with soft and dry cloth wetted 1% soap water when there are dust on the
Swell: The coefficient of heat is larger and its tension is about nine times of other metal materials. Remain enough space for its contractility to variable temperature while you install and fix acrylic sheets
Special Instruction Under Installation
1.Reserve enough space for contractility, the elasticity of cast acrylic sheet per meter is as following, according to the temperature.
(A) After finishing processed acrylic novelties at 10 Centigrade, the temperature raises to 50 Centigrade 1000 x 6 x 105 x (50-10) = 2.4m/m (elongation) (B) After finishing processed acrylic novelties at 10 Centigrade, the temperature falls to -10 Centigrade 1000 x 6 x 105 x (30+10) = 2.4m/m (shrinkage) You can consult general settlements to prevent from
Troubles as following:
Reserve the frame
for contractility Making ellipical hole with screw
Cushion material as elastic as rubber Making acrylic novelties into unprominent shape. Using form to increase the cross-sectional coefficient
avoiding interior stress.
Forming acrylic sheets into wave, wrap and through to increase cross-sectional coefficient in order to prevent trans formation from the weight of acrylic sheet itself and lasing.
Increasing thickness of acrylic sheet as larger length and dimension. Counting thickness, tension tolerance and bending strength of acrylic sheet to endure wind pressure on the surface.
