抽沙管道和普通聚乙烯区别
机械性能高于一般的高密度聚乙烯。具有突出的抗冲击性、耐应力开裂性、耐高温蠕变性、低摩擦系数、自润滑性,卓越的耐化学腐蚀性、抗疲劳性、噪音阻尼性、耐核辐射性等。
Mechanical properties are higher than general high density polyethylene. It has outstanding impact resistance, stress cracking resistance, high temperature creep resistance, low friction coefficient, self-lubrication, excellent chemical corrosion resistance, fatigue resistance, noise damping, nuclear radiation resistance and so on.
