Beijing calm down
Aramid packing consisting of silicone or Teflon oil; It has antiseptic properties, which have increased the use of this packing and this product can be used in hygienic environments.
The main material of this packing is aramid or Kevlar fibers. These fibers are one of the suitable alternatives to asbestos fibers.
Kevlar fibers with admirable strength have the honor of being used in various industries such as military, aerospace, ballistics and defense and are also used in sewing bulletproof vests. These fibers have good resistance against chemical corrosion and oxidation. Indicates and transfers little heat.
The heat tolerance of packing aramid is as follows:
The thermal tolerance of aramid fibers is 340 ° C.
The melting point of Kevlar packing is 500 degrees Celsius.
If impregnated with silicone or Teflon oil, its heat tolerance reaches 280 degrees Celsius.
The minimum temperature is minus 200 degrees Celsius.
Aramid packing with rectangular cross section, in addition to having high strength, has features such as light weight, acceptable mechanical properties, pressure control, significant impact strength, etc., and the ductility and flexibility of this packing due to It contains silicone or Teflon oil.
The most important benefits of aramid packing include:
Resistant to high temperatures up to 280 ° C if soaked in Teflon oil
Suitable density between 1.4 to 1.5 grams per cubic centimeter
Dimensional stability and preservation of the mold and shape at low temperatures up to minus 200 degrees Celsius
Ability to control pressures
Very high strength comparable to steel
Significant resistance to abrasion and tension
Has waterproof properties on the side of materials such as epoxy
Significant impact strength
Used in sanitary places due to Teflon in the product
Acceptable ductility and flexibility properties
Can be used to insulate shafts at high speeds up to 25 meters per second
Used in various spaces
Chemical resistance in the range of 2 PH to 12
Acceptable performance against weak alkalis and acids, hot water, sewage
Grease and oil
By examining the features of this packing, we will deal with its most significant applications:
Sealing of nuclear or industrial centrifuges
Insulation of various types of industrial pumps and tanks
Sealing of industrial parts
Sealing of power plant components and boilers
