Tsawg Kub Resistant FKM
Fluoroelastomer FKM Terpolymer Gum-246 series yog terpolymer ntawm vinylidenefluoride, tetrafluoroethylene thiab hexafluoropropylene.Vim nws cov ntsiab lus fluorine siab, nws cov roj hmab vulcanized muaj cov khoom zoo heev los tiv thaiv roj thiab thermal stability. ntev, nyob rau hauv 320 ℃ rau ib lub sij hawm luv luv.Cov khoom ntawm antil roj thiab anti acid yog zoo dua FKM-26, tsis kam ntawm FKM246 rau roj, ozone, hluav taws xob, hluav taws xob thiab flamer zoo li FKM26.

Khoom siv
FKM246 yog dav siv nyob rau hauv tsheb, machinery, petrochemical, thiab lwm yam liaj teb.Piv txwv li, lub dav hlau zoo li qub / dynamic seals cov ntaub ntawv ntawm hydraulic system thiab lubrication system; siv nyob rau hauv drilling cov cuab yeej thiab roj pipelines; tshuaj lom neeg kev lag luam rau cov cuab yeej siv, hloov yeeb nkab txuas, liner ntawm lub twj tso kua mis los yog corrosion-resistant sealing khoom, ua los ntawm cov kav dej nqa cov kuab tshuaj los yog lwm yam xov xwm, xws li corrosion.

Nco ntsoov
1.Fluoroelastomer terpolymer roj hmab muaj cua sov zoo nyob rau hauv 200 ℃ .Nws yuav tsim kab decomposition yog muab tso rau ntawm 200-300 'C ntev, thiab nws decomposing ceev ceev tshaj 320 ℃, cov khoom decomposition yog tsuas yog tshuaj lom hydrogen fluoride. thiab fluorocarbon organic compound.Thaum nyoos 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 no 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.
