Product description

Description   

Carbonized fibre packing is a braided packing made of carbonized poly acrylonitrile fibre. And carbonized fibre packing is finished with PTFE dispersion and lubricant. This gland packing covers wide range of application. For example, carbonized fibre packing can seal water,brine,factory wastes alt solutions,mineral oil etc. It can be also used for centrifugal pimps,agitators,mixers,sterntubes etc. Whats more, carbonized fibre packing is relatively economic among non-asbestos packing. So carbonized fibre packing is widely used as its economical and bread-and-butter character.                                                                                   

Application  

It can be used in weak acids and alkali or media containing few grains of solid particles, both dynamic and static, mainly used for centrifugal pumps, plunger pumps, mixers and valves. Particularly ideal for hot water, condensate and main coolant pumps.

Feature

1. It has small coefficient of friction(u=0.3), well self lubrication,and it can save energy consumption and reduce the damage to counterpart to prolong its service life.

2. It has well heat conductivity,near the one of metal(10~20kcal),when it is used to the dynamic sealing part with high speed, it can conduct the heat of fabrication out. Therefore, it can avoid the burning of material caused by accumulated heat to prolong its service life,and lower the the requirement for cooling of sealing sections.

3. It can be applied to speed sealing. For example: it can get well sealing on high pressure pump with a linear velocity of 25m/s.

4. It has stable chemical property:as part of the organic components of synthetic fibre have been eliminated during the process,and only carbon is remained,so its chemical property is stable. Meanwhile, in the course of production,there will be a cover of PTFE on the fibre surface,which reinforces its stability of chemical property.
