桥架的生产制造原料中离不了关键的原料便是玻璃纤维，为什么会有这样的结论呢？山东电缆桥架厂家告诉您，玻璃纤维是光洁的圆柱型，横截面多正圆形，别的有机纤维的外型有深的皱褶，横截面呈不规律情况，与树脂粘结时，玻纤表层因光洁导致抱协力小，不好粘结，可是玻纤间的间隙非常容易添充，它是有益的一面。

The key raw material in the production of cable tray is glass fiber. Why do you come to this conclusion? Shandong cable tray manufacturer tells you that glass fiber is smooth and clean cylindrical, and its cross section is mostly round. Other organic fibers have deep wrinkles in their appearance, and their cross section is irregular. When bonding with resin, the surface of glass fiber is smooth and clean, resulting in less cohesive force and poor bonding. However, the gap between glass fibers is very easy to fill, which is a beneficial aspect.

玻璃纤维的直径越密，软性越好，玻纤的耐磨性能、抗扭折耐热性很差，仅有棉絮的四分之一到五分之一，在纺织品生产过程中非常容易起球，进而减少了抗压强度，因而在金属拉丝时务必应用浸润剂。

The denser the diameter of the glass fiber, the better the flexibility. The abrasion resistance, torsion resistance and heat resistance of the glass fiber are very poor, only one-quarter to one-fifth of the cotton wadding. It is very easy to pilling in the textile production process, thus reducing the compressive strength. Therefore, the sizing agent must be used in metal wire drawing.

另外玻璃纤维的拉伸强度高，但也受到生产方式、化学成分、温度、湿度等因素影响，玻璃钢桥架耐腐蚀的性能是众所周知的，但是玻璃钢桥架对于氢氟酸、浓碱、热浓磷酸却很过敏，千万不可直接接触这些化学物质，除这几种以后，玻璃钢桥架对所有化学药品和有机溶剂都有良好的化学稳定性。

In addition, the tensile strength of glass fiber is high, but it is also affected by production mode, chemical composition, temperature, humidity and other factors. The corrosion resistance of glass fiber reinforced plastic bridge is well-known, but the glass fiber reinforced plastic bridge is very sensitive to hydrofluoric acid, concentrated alkali, hot concentrated phosphoric acid, and you must not directly contact these chemicals. In addition, the glass fiber reinforced plastic bridge has good chemical stability to all chemicals and organic solvents.

玻璃纤维有一个特性，便是拉丝在加温时没有转变，而纱加温到250度时先澎涨，假如再提温反倒收拢，并且不可以还原，因而绷紧后提温，会由于收拢而破裂，假如桥架出现层次的状况有可能是玻璃纤维纱在生产制造时温度没有操纵好而造成的，在生产制造桥架的全过程中，玻璃纤维的耐高温水平远高于一般的树脂，因而挑选耐高温树脂也是十分必须的。

One of the characteristics of glass fiber is that the drawing does not change during heating, but the yarn rises when it is heated to 250 degrees. If the temperature is raised again, it will be folded back and cannot be restored, so the bridge will be broken due to folding after tightening. If the bridge is layered, it may be caused by the poor temperature control of glass fiber yarn during manufacturing. During the whole process of manufacturing the bridge, The high temperature resistance level of glass fiber is much higher than that of ordinary resin, so it is also very necessary to select high temperature resistant resin.
