Description
Technical Field
The utility model relates to the technical field of Teflon tubes, in particular to an explosion-proof high-temperature-resistant Teflon tube.
Background
Teflon, otherwise known as polytetrafluoroethylene, is commonly referred to as a "non-stick coating" or "easy-to-clean material". The material has the characteristics of acid resistance, alkali resistance and various organic solvents resistance, and is almost insoluble in all solvents. Meanwhile, the polytetrafluoroethylene has the characteristic of high temperature resistance and is extremely low in friction coefficient, so that the Teflon tube is applied to liquids such as ethylene glycol and the like which have corrosion risks to metals. However, when the existing teflon tube is used, the inner layer teflon tube and the middle layer protection structure are easy to move mutually, which is not beneficial to the shearing of the teflon tube and the welding of the joint.
