Description

PTFE special-shape parts is made of that Tetrafluoroethylene resin be molded or cut into blank, according to the samples or drawings provided by customers and then mechanical precision processing.

Sodium treatment：

Sodium treatmen that surface of PTFE special-shape parts is treated with Sodium naphthalene liquid to give its surface a special treatment, making the liquid and surface of etched PTFE special-shape parts to produce chemical reaction, tear off the surface of fluorine molecules. At this time, carbonization layer and some polar groups are left on the surface, so as to obtain activated PTFE. In this way,etched PTFE skived film can be bonded  with  rubber, metal, plastic, wood, non-metal and other materials. The surface of etched PTFE special-shape parts is brown.

advantage

 1.High bonding strength, long service time, long life, strong acid and alkali corrosion resistance, not easy to peel.

 2.Sodium treatment only produces effect on the surface, has no effect on the inside of PTFE special-shape parts,,does not affect its basic characteristics.

 3.As a result of sodium treatment of PTFE to maintain the low friction coefficient of the original material, machine operation is light, anti-climbing, small vibration.

 4.The damage of guide rail veneer is small, which ensures the manufacturing accuracy and prolongs the service life of the equipment.

Application

1、Anti-pollution machinery (such as textile, paper, pharmaceutical, food machinery) bearing sleeve.

2、Conveying alkali, solvent and other non-lubricating liquid machinery (such as blender, dyeing machine, pump).

3、Bushing working in acid, alkali and other corrosive environment (such as electroplating bath chemical equipment).

4、prohibit oil lubrication (such as oxygen equipment).

5、Oil lubrication (such as ultra-low temperature refrigerator, liquid fuel pump).

Size

Various specifications and shapes, according to customer samples or drawings for processing.
