Qalabka caagga ah ee caadiga ah - hordhaca sifooyinka FFKM
Qeexitaan FFKM: Caag la daarray waxa loola jeedaa tepolymer-ka etherka perfluorinated (methyl vinyl), tetrafluoroethylene iyo perfluoroethylene ether. Waxa kale oo loo yaqaan caag perfluoroether.
Sifooyinka FFKM: Waxay leedahay kuleylka iyo xasiloonida kiimikada ee barti iyo polytetrafluoroethylene. Heerkulka shaqada ee muddada-dheer waa - 39 ~ 288 ℃, heerkulka shaqada ee muddada gaaban wuxuu gaari karaa 315 ℃. Heerkulka jaban, weli waa caag, adag laakiin ma jabna, waana la foorarsan karaa. Way xasiloon tahay dhammaan kiimikooyinka marka laga reebo bararka dareerayaasha fluorinated.
Codsiga FFKM: waxqabadka habaynta liidata. Waxa loo isticmaali karaa xaaladaha fluororubber aanu karti u lahayn oo xaaladuhu aad u adag yihiin. Waxa loo isticmaalaa in lagu sameeyo shaabado adkaysi u leh warbaahinta kala duwan, sida shidaalka gantaalada, xudunta, oksidat, nitrogen tetroxide, fuming nitric acid, iwm, hawada, duulista, kiimikaad, batroolka, nukliyeerka iyo qaybaha kale ee warshadaha.
Faa'iidooyinka kale ee FFKM:
Marka lagu daro iska caabbinta kiimikada aadka u fiican iyo iska caabbinta kulaylka, alaabtu waa isku mid, oogada ayaa ka xor ah dhexgalka, dildilaaca iyo pinholes. Tilmaamahani waxay hagaajin karaan waxqabadka xidhitaanka, sii dheereeyaan wareegga hawlgalka waxayna si wax ku ool ah u yareeyaan kharashka dayactirka.
Ningbo Yokey Precision Technology Co., Ltd waxay ku siinaysaa doorasho dheeraad ah FFKM, waxaan ku habeyn karnaa kiimikada, caabbinta heerkulka sare, dahaarka, qallafsanaanta jilicsan, caabbinta ozone, iwm.
