Khoom siv
Dav siv rau kev tsim cov tshuab ntxhua khaub ncaws, gaskets, O-rings, V-rings, roj foob, diaphragms, roj hmab kav, cable sheaths, tshav kub rwb thaiv tsev ntaub, valve daim hlau, expansion pob qij txha, roj hmab rolls, coatings thiab pasty chav kub vulcanization putties nyob rau hauv lub sij hawm resisting kub, roj (pib roj), lubricating roj (synthetic roj), kua (ntau yam uas tsis yog-polar solvents). corrosion (acid, alkali), muaj zog oxidizer (oleum), ozone, hluav taws xob thiab huab cua.
Nco ntsoov
1. FKM muaj kev ruaj ntseg kub zoo nyob rau hauv 200 ℃.Nws yuav tsim cov kab decomposition yog tias muab tso rau ntawm 200-300 ℃ ntev, thiab nws cov decomposing ceev ceev tshaj 320 ℃, cov khoom decomposition yog cov tshuaj lom hydrogen fluoride thiab fluorocarbon organic. compound.Thaum raw fluorous roj hmab ntsib hluav taws, nws yuav tso tshuaj lom hydrogen fluoride thiab fluorocarbon organic compound.
2. FKM tsis tuaj yeem sib xyaw nrog cov hmoov hlau xws li txhuas hmoov thiab magnesium hmoov, lossis ntau dua 10% amine compound, yog tias qhov ntawd tshwm sim, qhov kub thiab txias yuav tshwm sim thiab ntau lub ntsiab lus yuav ua rau FKM, uas yuav ua rau cov khoom siv thiab cov neeg ua haujlwm puas tsuaj.
Pob, thauj thiab khaws cia
1.FKM tau ntim rau hauv PE hnab yas, thiab tom qab ntawd thauj mus rau hauv thawv, qhov hnyav ntawm txhua lub thawv yog 20kg.
2.FKM khaws cia rau hauv qhov chaw huv, qhuav thiab txias.Nws yog thauj raws li cov tshuaj tsis muaj kev phom sij, thiab yuav tsum tsis txhob muaj cov pa phem, tshav ntuj thiab dej thaum lub sijhawm thauj mus los.
