衬里层 meaning in Chinese
backing layer
Examples
- 4 testing proving and using bound of pading ptfe inside lining
四内衬ptfe衬里层试验检验及使用范围 - 1 pipelines and pipeparts are all put to hydraulic pressure test to design in 1 . 5 multiple
2凡涉及内衬ptfe衬里层经水压试验后， - Adopt advanced technic of f4 whole cold - press to moulding and heat melt to process to make , let the lining no slot to link withal cheek by jowl connect with exterior metalpipes wall , in the state of allowwing to work keep to distort in - phase , thereby to enhance using - life of lining in the working status of opposite high temperature high vacuum , stop the ecumenic pad fluorin pipes using in condition of cold and heat alternate and minus tension to come into being the matter of padding fluorin floor shrivel to jam the flowway and plastic rip , its perfect choice use to transport medium of strong corrosive strong oxidation by modern chemical - industry corporation
采用氟塑料f4整体冷压成型及热熔加工等先进技术制造，使内衬层无缝搭接且与外层金属管壁紧密粘接，在允许工作状态下能够保持同步变形，从而提高了衬里层在相对高温高真空度的工况下的使用寿命，杜绝了一般衬氟管在冷热交替，及负压的条件下使用易产生衬塑层鼓瘪阻塞流道及塑料拉裂的问题，是现代化工企业在输送强腐蚀强氧化介质理想的选择。 - 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。
