Teflon spray-conductive coating

       

When the Teflon spray is manufactured, a small amount of conductive additives is added. 

When used as a hose in the aviation industry hydraulic system, the inner tube will accumulate static charges due to friction during the high-speed flow of hydraulic oil, resulting in electrostatic danger. A trace amount of conductive additives must be added during the manufacture of the FE inner tube, usually carbon black or graphite. Eliminate static electricity and increase safety performance, that is, the inner layer of the tube is a uniform mixture of a certain proportion of conductive graphite and PTFE, and the outer layer of the tube is pure PTFE. The inner layer of this type of tube has conductive properties.

 

The main purpose of the sprayed Teflon hose is to transport hydraulic fluid in the aerospace industry, such as a pressure tube for high-speed fuel delivery in spacecraft such as jets and rockets. High-pressure air in the automobile industry, the transportation of highly corrosive media in the chemical industry, and the passage of high-purity fluids in the pharmaceutical industry. In the civil industry, it is suitable for the soft connection of hydraulic pressure, steam pressure, steam transmission, etc. in rubber, plastics, pharmaceuticals, clothing, shipbuilding, automobiles, machine tools, electric welding machines, diesel engines, papermaking and other industries.

 

The process is as follows:

 

Inner resin (contains conductive material) → outer resin → mixed compact → extrusion molding → high temperature sintering → cooling → shaping → inspection → weaving → joint assembly → inspection

 

PTFE steel wire composite hoses are mainly used for hydraulic systems, air-conditioning systems, fuel systems and Teflon spray lubricating oil systems on aircraft.
