| 聚氨酯电缆槽产品优势：原材料聚氨基甲酸酯（简称聚氨酯），以其韧性好、固化快、无苯乙烯烟雾等有点使其在复合材料中脱颖而出。主要成份聚氨酯、玻璃纤维，具有优异的拉伸特性、抗冲击性和耐腐蚀性。其典型拉伸强度约880kg/cm2，拉伸模量约30230kg/cm2，断裂伸长率为7.5%以上。经过发泡的聚氨酯复合材料还可减重达20%。与不饱和聚酯、乙烯基酯等其他树脂相比，聚氨酯全面提高了产品的物理性能。 Advantages of polyurethane cable trough products: the raw material polyurethane (polyurethane for short), with its good toughness, fast curing, no styrene smoke and so on, makes it stand out in the composite materials. The main components are polyurethane and glass fiber, which have excellent tensile properties, impact resistance and corrosion resistance. Its typical tensile strength is about 880Kg / cm2, tensile modulus is about 30230kg / cm2, and elongation at break is more than 7.5%. After foaming, the weight of polyurethane composite can be reduced by 20%. Compared with other resins such as unsaturated polyester and vinyl ester, polyurethane improves the physical properties of products. 聚氨酯的强度和刚度性能比不饱合聚酯树脂高2～5倍。因产品优异的韧性，聚氨酯复合电缆桥架经加工和冲切的边缘显现极少甚至没有微裂纹，表面很硬，孔隙率低，有利于后道加工如钻孔、机械加工和装配等作业。与不饱和聚酯、乙烯基酯等树脂拉挤产品相比，用聚氨酯拉挤在现场施工方便程度上，以及使用年限上具有一定的优势。 The strength and rigidity of polyurethane are 2-5 times higher than that of unsaturated polyester resin. Due to the excellent toughness of the product, the edges of polyurethane composite cable tray after processing and punching show little or no microcracks, the surface is very hard, and the porosity is low, which is conducive to subsequent processing such as drilling, machining and assembly. Compared with unsaturated polyester, vinyl ester and other resin pultrusion products, polyurethane pultrusion has certain advantages in field construction convenience and service life. |
