冷流性 meaning in Chinese
cold flow property
Examples
- Ptfe is one of the most corrosion - resistant materials in the world . however it has defects such as the hot expansion and cold contraction rate is10 times larger than that of steel and the original cold fluidity ( creeping ) etc . therefore , as temperature increases , ptfe extends so excessively that it would collapse and then block the flow of media ; as temperature decreases , ptfe contracts so excessively that it would be ripped and then cause leakage
Ptfe是当今最耐腐蚀的材料之一，可它被制造成衬里的时候，会存在热胀冷缩比钢铁十多倍及固有的冷流性等缺陷，致使ptfe衬里管道、设备，在使用过程中，温度高时， ptfe衬里层会伸长过多而内瘪，阻塞了介质流通；温度低时， ptfe层会收缩过大被拉裂而泄漏。
