  • 玻璃钢储罐强度为什么这么大

什么可以让玻璃钢储罐耐腐蚀而且强度大呢?其实主要得归功于玻璃纤维。

作为玻璃钢用的玻璃纤维:其拉伸强度是一个很重要的物理指标,块状玻璃的强度不高,很容易断裂,而其拉成玻璃纤维后不仅获得柔软性并且强度大大提高。

玻璃纤维强度高的原因:

贵州快3微裂纹假说,玻璃的理论强度取决于分子或原子间的吸引力,其理论强度很高,可达200~1200kgf/m㎡,但是实测强度很低,这事因为玻璃或者玻璃纤维中存在着数量不等、尺寸不同的微裂纹,因而大大降低了强度。微裂纹分布在玻璃整个体积内。

贵州快3玻璃纤维比块状玻璃的强度高很多,这是因为玻璃纤维在高温成型时减少玻璃溶液的不均一性,使微裂纹产生的机会减少,此外玻璃纤维的断面较小,并伴随着表面积的减少,微裂纹存在的机率也减少,从而强度增加,这也是为什么玻璃钢储罐强度高的原因所在。

What makes a FRP tank corrosion-resistant and strong? Actually, it's mostly the fiberglass. As a glass fiber used for frp, its tensile strength is a very important physical index, the strength of the block glass is not high, it is easy to break, and its tensile into glass fiber not only to obtain flexibility and strength is greatly improved. The reason for the high strength of GLASS FIBER: The micro-crack hypothesis, the theoretical strength of glass depends on the attraction between molecules or atoms, its theoretical strength is very high, up to 200 ~ 1200 KGF / M2, but the measured strength is very low, this is due to the presence of micro-cracks of varying amounts and sizes in glass or fiberglass, which greatly reduces strength. The microcracks are distributed in the whole volume of the glass. The strength of glass fiber is much higher than that of bulk glass. This is due to the fact that glass fiber is formed at high temperature to reduce the heterogeneity of glass solution, which reduces the chance of micro-cracks and the small cross-section of glass fiber, with the decrease of surface area, the probability of microcrack is decreased, and the strength is increased, which is the reason why the strength of FRP tank is high.
