什么是低温脆性?低温脆性是指材料的冲击吸收功随温度降低而降低,淮安PVC管业,当试验温度低于Tk(韧脆临界转变温度)时,冲击吸收功明显下降,材料由韧性状态变为脆性状态,这种现象称为低温脆性。
What is low temperature brittleness? Low temperature brittleness means that the impact absorbed energy of material decreases with the decrease of temperature. When the test temperature is lower than TK (critical transition temperature of toughness and brittleness), the impact absorbed energy decreases clears, and the material changes from ductile state to brittle state. This phenomenon is called low temperature brittleness.
PPR管为什么会有低温脆性的特点?它是由单体和少量乙烯单体在加热、加压和催化剂作用下无规共聚得到的。乙烯单体随机地分布到长链中,其中乙烯单体一般控制在3-5%之间。乙烯含量和乙烯与的聚合方式决定了其具有低温脆性的特点。
Why does PPR pipe h***e the characteristics of low temperature brittleness? It is obtained by random copolymerization of monomer and a ***all amount of ethylene monomer under heating, pressure and catalyst. Ethylene monomer is randomly distributed in long chain, and ethylene monomer is generally controlled between 3-5%. The content of ethylene and the polymerization of ethylene determine its low temperature brittleness.Uk Gafloon Pipe Group Ltd,PVC管业加工,厂家位于:Chase Business Centre London England,追求品质生活,详情欢迎来电咨询访问。
