The force that press a gram have what features

It is a general term for acrylic type of chemicals. In the field of plastic, acrylic refers to the PMMA polymethylmethacrylate, is a kind of thermoplastic engineering plastics with excellent comprehensive performance. The most prominent feature of the force that press a gram is crystal clear, the light transmittance was 92%, and the plastic material. The force that press a gram or all plastic for ultraviolet ( UV） The least sensitive. The force that press a gram also is very not easy oxidation, weather resistance is very strong. Acrylic plate casting plate and extrusion plate according to the production process; According to the product performance can be divided into the transparent board ( Including dyeing transparent board) And the color plate ( Both black and white and color board) , the common plate and special plate, such as: high impact plate, grinding plate, metal effect, high wear-resisting board, fire board, guide plate, etc. Acrylic plate has pervious to light, durable, shape, and color and the surface effect of diversified characteristics.

inspection rules.

(1) acrylic sheet coated on both sides. Jie membrane sampling at the time of acceptance.

2 jie membrane sampling of acrylic sheet for full inspection, mainly to check whether there is damage, coated outside to have damage to the coated parts to do local jie film test.

the quality inspection standards;

(1) the surface are not allowed to have residual silicon, silicon glass cracks, crazing, crack, surface shrink marks and obvious surface scratch;

2 allows fine scratches and foreign material dispersion is not obvious;

(3) the whole plate is less than 2 ㎜ bubble diameter does not exceed 2;

(4) length, the width deviation & le; ± 2．0㎜（ Width size will be subject to available plate boundary)

5] thickness & le; 0 ㎜, deviation & le; ± 0 ㎜, deviation & le; ± 0．2㎜
