好的FRP采光板为什么会脆？
1、好的采光板除了选用高品质的抗UV膜和优质树脂外，其生产固化度也是重要的一条。内部分子结构呈近似均匀的网状结构，该结构非常稳定，外界的紫外线、水汽、酸碱物质等很难对其造成大的影响。因为采光板固化度提高以后，伴随的其硬度，机械强度（拉伸强度、弯曲强度等）也会很高，同时表现的相对较脆。
1. In addition to selecting high-quality anti-film and high-quality resin, the curing degree of a good daylighting board is also an important factor in its production. The internal molecular structure is nearly uniform network structure, which is very stable. It is difficult for the external ultraviolet, water vapor, acid and alkali substances to have a great impact on it. As the curing degree of daylighting board increases, its hardness, mechanical strength (tensile strength, flexural strength, etc.) will also be very high, while the performance is relatively brittle.
2、采光板作为一建筑材料，它首先须具有一定的刚度和弯曲强度以保证在受到外力的情况下，变形较小。这样的话可以避免因受到外力而使密封胶和防水处理失败，有效地防止漏水。
2. As a building material, daylighting board must have certain stiffness and flexural strength to ensure that under external force, the deformation is small. In this way, the failure of sealant and waterproof water treatment due to external force can be avoided, and the leakage can be effectively prevented.
3、国内的很多采光板为了增加采光板的韧性，在采光板中加了一种增塑剂（也即柔软剂）的物质。该物质可令采光板柔韧性很好，但强度会有很大影响。而且其在一段时间后会浮在采光板表面析出，又是一种高致癌物，在国外，尤其是欧盟国家，已经严令禁止。而且添加增塑剂（柔软剂）以后，采光板的耐老化性和寿命会大打折扣，这无异于饮鸩止渴。
3. In order to increase the toughness of many domestic daylighting boards, a plasticizer (softener) was added to the daylighting boards. The material can make the lighting board flexible, but the strength will have a great impact. Moreover, it will float on the surface of daylighting panels after a period of time, www.zhenkongfumoj.cnwww.biaozhiji.cn www.baojietangshan.cnwww.daxiaotou.com.cn www.yanglaoyuanl.cn www.diandongmenj.cnand it is also a high carcinogen, which has been strictly prohibited in foreign countries, especially in EU countries. Moreover, when plasticizer (softener) is added, the aging resistance and life of daylighting board will be greatly reduced, which is no different from drinking Poinsettia to quench thirst.
4、采光板作为一种钢结构辅件，是严禁踩踏的，采光板在屋面上搬运、吊装过程中按正确的操作方法和采光板正常的弯折变形，都不会对采光板造成损伤。
4. As a kind of steel structure accessory, the lighting board is strictly forbidden to trample. The lighting board will not cause damage to the lighting board in the process of handling and hoisting on the roof according to the correct operation method and the normal bending deformation of the lighting board.
