FKM (Terpolymer) fluoroelastomer xanjo-246
Fluoroelastomer FKM Terpolymer Gum-246 taxane waa terpolymer ee vinylidenefluoride, tetrafluoroethylene iyo hexafluoropropylene. Sababtoo ah maadada fluorine sare, caag vulcanized ah waxay leedahay hantida saliida anti heer sare ah iyo xasilloonida kulaylka sare.Waxa kale oo uu leeyahay hanti farsamo oo wanaagsan waxaana loo isticmaali karaa 275℃ muddo dheer, in 320 ℃ muddo gaaban. Hantida antil oil iyo anti acid ayaa ka fiican FKM-26, iska caabinta FKM246 ee saliidda, ozone, shucaaca, korontada iyo flamer waxay la mid tahay FKM26.

Isticmaalka Alaabta
FKM246 waxaa si weyn loogu isticmaalaa baabuurta, mishiinada, petrochemical, iyo beeraha kale.Tusaale ahaan, shaabadeynta firfircoon ee nidaamka hydraulic iyo nidaamka sifaynta; loo isticmaalo in qalab qodista iyo dhuumaha saliidda; warshadaha kiimikada ee qalabka, isku xirka tuubooyinka dabacsan, liner of bamka ama wax daboolaya daxalka, oo ka samaysan tubooyinka si ay u qaadaan dareeraha ama warbaahinta kale, sida daxalka.
Fiiro gaar ah
1.Fluoroelastomer terpolymer caag leeyahay xasilooni kulayl wanaagsan ka hooseeya 200 ℃.Waxay dhalin doontaa raad dami haddii lagu riday at 200-300'C muddo dheer, iyo xawaaraha ay qudhmi kor 320 ℃, alaabta kala furfuran yihiin inta badan hydrogen fluoride sun ah. iyo fluorocarbon organic compound. Marka caag cayriin ah oo cayriin ah ay la kulmaan dabka, waxay sii dayn doontaa sunta hydrogen fluoride iyo fluorocarbon organic compound.
2.FKM laguma qasi karo budada birta ah sida aluminium budada ah iyo budada magnesium, ama in ka badan 10% amiin, hadii ay taasi dhacdo heerkulku wuu kacayaa waxaana ka falcelinaya curiye dhowr ah oo FKM ah, taasi oo dhaawac u geysan doonta qalabka iyo hawl-wadeenada.
Xidhmada, Gaadiidka iyo Kaydinta
1.FKM waxaa lagu shubaa bacaha PE, ka dibna waxaa lagu shubaa kartoon, miisaanka saafiga ah ee kartoon kasta waa 20kg.
2.FKM waxa lagu kaydiyaa bakhaar nadiif ah, qalalan oo qabow, waxaana lagu raraa kiimikooyinka aan khatarta ahayn, waana in laga fogaadaa isha wasakhaysan, qoraxda iyo biyaha inta lagu jiro gaadiidka.
