Pneumatic valve anti-corrosion lining material profile

, PTFE (teflon F)
applicable medium: strong acid, strong alkali, strong oxidizing agents, etc. ; Use the temperature - ~ ℃;
features: excellent chemical stability, has high heat resistance, cold tolerance; Friction coefficient is very low, is an excellent self-lubrication material, but mechanical performance is low, liquidity is poor, thermal expansion.
and FEP FEP ( F)
applicable medium: any organic solvent or reagents, thin or thick inorganic acid, alkali, ketone, aromatic hydrocarbons, chlorinated hydrocarbons, etc. ;
use temperature: - ~ ℃;
features: mechanics, electricity performance and chemical stability, basically the same as the F, but outstanding advantage is dynamic toughness, and has excellent weatherability and radioactive.
, three fluoride PCTEF ( F
medium: apply to all kinds of organic solvent and inorganic corrosion liquid ( Oxidizing acids;
use temperature: - ~ ℃;
features: heat resistance, electric properties and chemical stability, second only to F, mechanical strength, creep properties, hardness is better.
, poly (vinylidene fluoride, PVDF ( F)
applicable medium: resistant to most chemicals and solvents.
use temperature: - ~ ℃;
features: the tensile strength and compression strength is better than F, bending resistance, weather resistance, radiation resistance, light and aging, the biggest characteristic is good toughness, easy to shape. RPP

and polypropylene applicable medium: inorganic salt aqueous solution of a class, the thin or thick inorganic acid, alkali solution;
use temperature: - ~ ℃;
features: one of the most light plastic, its yield, tensile and compression strength and hardness are better than that of low pressure polyethylene, there are outstanding rigidity; Good heat resistance, easy forming, optimal budget. Modified dynamic sex, liquidity, bending elastic modulus increase.

, polyene diameter PO applicable medium: various concentration of acid and alkali salts and some organic solvents;
use temperature: - ~ ℃;
characteristics: it is currently one of the world's most ideal anticorrosion material, has been widely used in large rotational molding equipment and pipe lining.
, polyvinyl chloride ( Hard) PVC
applicable medium: water, strong alkali, the oxidation resistance acid, chain hydrocarbon, oil and ozone, etc. ;
use temperature: ~ ℃;
characteristics: high mechanical strength, chemical stability and good dielectric properties, oil resistance and anti senile is better also, easy to welding and adhesion, low price.
all kinds of lining pipe pneumatic valve the same nominal size of the shell and connection size are the same, but the lining material according to different medium, can adopt the following different lining material: PO, polypropylene RPP, modified polyolefin, teflon fep F F, three fluoride, poly (polyethylene F F.
