Raw materials for glass plate

1、增强材料
1. Reinforced materials
FRP 板通常选用的增强材料为玻璃布,无捻玻璃粗纱,短切玻璃纤维毡。
The reinforcing materials commonly used in FRP board are glass cloth, twisting glass roving and short glass fiber felt.

无捻玻璃粗纱:连续FRP波纹成型工艺所用无捻玻璃粗纱应具有良好的切割性,分散性, 树枝浸润性,不产生或少产生静电。
Twist glass roving: the non twist glass roving used in the continuous FRP ripple molding process should have good cutting, dispersivity, branch wettability, and no generation or less static electricity.

短切玻纤毡目前国内通常采用的短切玻璃纤维毡的规格有,EMC300、EMC450、EMC600三种,具有密度均匀,浸透性好,无污染,耐候,透光等特点。(通常选用的是粉剂毡)
Short cut glass fiber felt is commonly used in domestic short cut fiberglass felt, such as EMC300, EMC450 and EMC600, which have the characteristics of uniform density, good permeability, no pollution, weatherability, light transmission and so on. (usually used for powder felt)

2、树脂基体
2. Resin matrix
连续FRP波纹板成型工艺多数选用不饱和聚酯树脂(UP)树脂,具有较高的机械强度,良好的耐候性和耐冲击性,还要具有较低的收缩率以及适当的粘度, 以便对玻璃纤维有良好的浸渍性,排泡性。
The continuous FRP corrugated plate forming process is mostly unsaturated polyester resin (UP) resin, with high mechanical strength, good weatherability and impact resistance, but also with low shrinkage and proper viscosity, so that the glass fiber has good impregnation and foaming
