PERFLUOROELASTOMERS Cov
Perfluoroelastomers (FFKM) feem ntau yog tsim los ntawm tetrafluoroethylene, perfluoromethyl vinyl ether, thiab vulcanization point monomers, thiab muaj kev tiv thaiv zoo heev rau tshuaj, tshav kub, extrusion, thiab high-temperature compression deformation.Tsuas yog qee cov kuab tshuaj fluorocarbon siab, lawv tsis cuam tshuam los ntawm ib qho nruab nrab, suav nrog ethers, ketones, esters, amides, nitriles, muaj zog oxidizing cov neeg ua haujlwm, fuels, acids, alkalis, thiab lwm yam. khoom.

Cov ntawv thov tseem ceeb
1.Cov khoom no yog triazine vulcanized perfluoroelastomer, siv nyob rau hauv qhov kub ntawm 275 ℃ to 300 ℃.Nws tuaj yeem siv rau lub sijhawm luv luv ntawm qhov kub siab txog 315 ℃.Perfluoroelastomers yog siv los ua cov roj hmab foob thiab cov khoom uas tiv taus qhov kub thiab txias.strong corrosive media, thiab cov kuab tshuaj feem ntau, xws li diaphragms, sealing rings, V-shaped sealing rings, O-rings, packers, solid balls, gaskets, sheaths, khob, kav dej, thiab li qub.
2.Mainly siv nyob rau hauv aviation, aerospace, tshuaj kev lag luam, petroleum.atomic zog, semiconductor thiab lwm yam felds.
Daim ntawv thov
1.Thaum raw perfluoroelastomers ntsib hluav taws, nws yuav tso tshuaj lom hydrogen fluoride thiab fluorocarbon organic compound.
2.Perfluoroelastomers tsis tuaj yeem sib xyaw nrog cov hmoov hlau xws li txhuas thiab magnesium hmoov, lossis ntau dua 10% amine compound, yog tias qhov no tshwm sim, qhov kub thiab txias yuav tshwm sim thiab ntau lub ntsiab lus yuav ua rau cov tshuaj perfluoroelastomers, uas yuav ua rau cov khoom siv thiab cov neeg ua haujlwm puas tsuaj.
Pob, thauj thiab khaws cia
1.Perfluoroelastomers tau ntim rau hauv PE hnab yas thiab ces ntim rau hauv cov thawv ntawv.Net nyhav yog 20Kg ib lub thawv.
2.Perfluoroelastomers raug thauj raws li cov tshuaj tsis muaj kev phom sij.3.Perfluoroelastomers khaws cia rau hauv dean, qhuav thiab txias warehouse, thiab yuav tsum kom deb ntawm cov pa phem qhov chaw, tshav ntuj thiab dej thaum lub sij hawm kev thauj mus los.
