Ubushyuhe Buke Kurwanya FKM
Fluoroelastomer FKM Terpolymer Gum-246 ni terpolymer ya vinylidenefluoride, tetrafluoroethylene na hexafluoropropylene. Kubera ibirimo fluor nyinshi, reberi y’ibirunga ifite imitungo myiza ya peteroli kandi irashobora gukoreshwa neza muri 275 ℃ igihe kinini, muri 320 ℃ mugihe gito.Umutungo wamavuta ya antil na anti aside uruta FKM-26, kurwanya FKM246 kumavuta, ozone, imirasire, amashanyarazi na flamer bisa na FKM26.

Gukoresha ibicuruzwa
F. liner ya pompe cyangwa ibikoresho bidashobora kwangirika, bikozwe mu miyoboro yo gutwara imashanyarazi cyangwa ibindi bitangazamakuru, nka ruswa.
Icyitonderwa
1.Fluoroelastomer terpolymer reberi ifite ubushyuhe bwiza munsi ya 200 ℃ .Bizabyara imishwarara iyo ishyizwe kuri 200-300'C mugihe kirekire, kandi umuvuduko wacyo wihuta uri hejuru ya 320 ℃, ibicuruzwa byangirika ahanini ni fluoride ya hydrogène. na fluorocarbon organic compound.Iyo reberi mbisi ya fluor ihuye numuriro, izarekura hydrogène hydrogène fluoride hamwe na organic fluorocarbon organic organic.
2.FKM ntishobora kuvangwa nifu yicyuma nka pome ya aluminium nifu ya magnesium, cyangwa ifumbire ya amine irenga 10%, nibiramuka bibaye, ubushyuhe buzaduka kandi ibintu byinshi bizitwara hamwe na FKM, byangiza ibikoresho nababikora.
Amapaki, Gutwara no Kubika
1.FKM ipakiye mumifuka ya plastike ya PE, hanyuma igashyirwa mubikarito, uburemere bwa buri karito ni 20kg.
2.FKM ibikwa mu bubiko busukuye, bwumye kandi bukonje.Butwarwa hakurikijwe imiti idafite ingaruka, kandi bugomba kwirinda inkomoko y’umwanda, izuba n’amazi mugihe cyo gutwara.
