The influence of 1. raw materials on the transmittance of PC plate

一般的厂家对PC阳光板有几种档次，分别对应的原料有进口全新原料、国产全新原料、以及掺有回收料的产品，由于板材的生产过程简单来说便是原料热熔，然后通过挤出成型，最后共挤抗老化UV涂层、防雾滴层，以及最后的保护膜等工序。

The general manufacturer has several grades to the PC sun plate. The corresponding raw materials include new imported raw materials, new raw materials made in China, and products with recycled materials. Because the production process of the plate is simple, it is the hot melt of raw materials, and then extruded through extrusion, and finally coextruding anti aging UV coating, anti fog layer, and last guarantee. Membrane protection and other processes.

因此也可以看出，原材料如果本身掺有回收旧料，因为原料的泛黄就会导致成品板材出现发黄的情况，其透光率自然会下降；而具体的透光率要看回收料的质量以及原料中旧料的掺有比例。

Therefore, it can be seen that if the raw materials are added to the old materials, the yellowing of the raw materials will lead to the yellowing of the finished products, and the transmittance of the raw materials will decrease naturally; and the specific light transmittance depends on the quality of the recycled material and the proportion of the old material in the raw material.

2. 厚度对PC板材透光率的影响 

The influence of 2. thickness on the transmittance of PC plate

无论是实心耐力板还是中空的阳光板，其透光度都会随着厚度的增加略有降低。耐力板的幅度不会很大，但是阳光板的下降幅度会有很大的变化，定主要原因在于阳光板为多层结构，中间为中空的空洞，光照经过每层的折射就会导致最后的透光率发生很大的变化。
