PTFE gasket has excellent resistance to high and low temperature and chemical stability, good electrical insulation properties, non-adhesion, weather resistance, flame retardancy and good self-lubricity. It has been used in chemical industry, petroleum, Textile, electrical and electronic, medical, mechanical and other fields have been widely used.

In fluoroplastics, PTFE has a large consumption and is widely used, and is an important variety in fluoroplastics. PTFE has excellent high and low temperature resistance and chemical stability, good electrical insulation properties, non-adhesion, weather resistance, flame retardancy and good self-lubricating properties. It has the reputation of “Plastic King”. The material was developed for the needs of national defense and cutting-edge technology, and then gradually extended to civilian use. Its use covers many aspects of aerospace and civil applications and is now an indispensable material in its application.

The friction coefficient of PTFE gasket is small, the self-lubricating function is excellent, the working characteristics of the guide rail pair are improved, the machining precision of the machine tool is improved, the service life of the machine tool guide is prolonged, and the energy consumption of the machine tool is reduced. Dongguan PTFE gasket When the manufacturer lubricates with machine oil, the oil lubrication friction coefficient is 0.03, the dry friction coefficient is 0.06, which is only 1/3 of the cast iron guide pair. Moreover, the friction speed characteristic curve of the PTFE gasket and the cast iron pair is a positive slope, and the difference of the static friction coefficient is small, which can effectively prevent the low speed.

The wear amount is small, and the test is repaired on the lathe rail with a Teflon gasket. After 3 months of normal operation, the wear of the soft belt is <0.03 mm. The bed rails are intact.

The bonding strength is high and the tensile strength can fully meet the process requirements. In the past, once the guide rail was poorly lubricated or there was any foreign matter waiting for the debris, the friction surface of the guide rail was pulled into the rail and the rail was pulled. Usually, it could only be repaired by tin-bismuth alloy brazing or brush-plated rapid nickel method, but the rail could not be re-strained, since the guide rail After the Teflon gasket is attached, the cast iron guide rail is well protected because of its self-lubricating properties and the fitting of foreign matter such as chips.
