Yakaderera Tembiricha Inodzivirira FKM
Fluoroelastomer FKM Terpolymer Gum-246 yakatevedzana ndiyo terpolymer yevinylidenefluoride, tetrafluoroethylene uye hexafluoropropylene.Nekuda kweiyo yakakwira fluorine, rabha yakasvibiswa ine yakanakisa antioiri midziyo uye yakakwirira yekupisa kugadzikana.Iyo zvakare ine yakanaka 5 midziyo yekushandisa uye kwenguva yakareba, mu 320 ℃ kwenguva pfupi.Nzvimbo ye antil mafuta uye anti acid iri nani pane FKM-26, kushorwa kweFKM246 kumafuta, ozone, mwaranzi, magetsi uye flamer zvakafanana neFKM26.

Product Use
FKM246 inoshandiswa zvakanyanya mumotokari, muchina, petrochemical, uye mimwe minda. Semuyenzaniso, iyo ndege static / dynamic seals zvinhu zvehydraulic system uye lubrication system; inoshandiswa mukuchera midziyo nemapombi emafuta; indasitiri yemakemikari yemidziyo, inochinjika pombi yekubatanidza, liner yepombi kana corrosion-resistant sealing material, yakagadzirwa nemapombi ekutakura zvinonyungudutsa kana zvimwe zvinobudisa nhau, zvakaita sekuora.
Attention
1.Fluoroelastomer terpolymer rubha ine yakanaka kudzikama pasi pe200 ℃.Ichagadzira trace decomposition kana ikaiswa pa200-300'C kwenguva yakareba, uye kukurumidza kwayo kuparara kunowedzera kupfuura 320 ℃, zvigadzirwa zvekuora zvinonyanya chepfu hydrogen fluoride. uye fluorocarbon organic compound.Kana raw mbishi rabha rasangana nemoto, inoburitsa muchetura wehydrogen fluoride uye fluorocarbon organic compound.
2.FKM haigoni kusanganiswa nehupfu hwesimbi yakadai sealuminium poda uye magnesium powder, kana kupfuura10% amine compound, kana izvozvo zvikaitika, kutonhora kuchamuka uye zvinhu zvakawanda zvinopindirana neFKM, iyo ichakuvadza midziyo uye vashandi.
Package, Kutakura uye Kuchengeta
1.FKM yakarongedzwa mumabhegi epurasitiki ePE, uye yozoiswa mumakatoni, huremu hwekatoni imwe neimwe ndeye 20kg.
2.FKM inochengetwa munzvimbo yakachena, yakaoma uye inotonhorera. Inotakurwa maererano nemakemikari asina ngozi, uye inofanira kuchengetedza kure nekusvibiswa kwemhepo, zuva uye mvura panguva yekufambisa.
