FKM (Terpolymer) fluoroelastomer chịngọm-246
Fluoroelastomer FKM Terpolymer Gum-246 usoro bụ terpolymer nke vinylidenefluoride, tetrafluoroethylene na hexafluoropropylene. N'ihi na nke elu fluorine ọdịnaya, ya vulcanized roba nwere magburu onwe mgbochi mmanụ onwunwe na elu thermal kwụsie ike.It nwekwara ezi n'ibu ihe onwunwe na ike ga-eji na 275℃. ruo ogologo oge, na 320 ℃ maka obere oge. Ihe onwunwe nke antil mmanụ na mgbochi acid dị mma karịa FKM-26, nkwụsị nke FKM246 na mmanụ, ozone, radieshon, ọkụ eletrik na flamer yiri FKM26.

Eji ngwaahịa
A na-eji FKM246 n'ọtụtụ ebe na ụgbọ ala, igwe, petrochemical, na mpaghara ndị ọzọ. Dịka ọmụmaatụ, ihe mkpuchi siri ike nke sistemu hydraulic na sistem lubrication; eji akụrụngwa akụrụngwa na pipeline mmanụ; ụlọ ọrụ kemịkalụ maka akụrụngwa, njikọ ọkpọkọ na-agbanwe agbanwe, liner nke mgbapụta. ma ọ bụ ihe mkpuchi na-eguzogide corrosion, nke ejiri ọkpọkọ mee ihe na-ebu ihe mgbaze ma ọ bụ mgbasa ozi ndị ọzọ, dị ka corrosion.
Nlebara anya
1.Fluoroelastomer terpolymer roba nwere ezigbo okpomọkụ kwụsie ike n'okpuru 200 ℃.It ga-n'ịwa Chọpụta decomposition ma ọ bụrụ na-etinye na 200-300'C ruo ogologo oge, na decomposing ọsọ accelerates na n'elu 320 ℃, decomposition ngwaahịa bụ tumadi hydrogen fluoride. na fluorocarbon organic compound.Mgbe raw fluorous roba zutere ọkụ, ọ ga-ahapụ hydrogen fluoride na-egbu egbu na fluorocarbon organic compound.
2.FKM enweghị ike ịgwakọta ya na ntụ ntụ ígwè dị ka aluminom ntụ ntụ na magnesium ntụ ntụ, ma ọ bụ ihe karịrị 10% amine compound, ọ bụrụ na nke ahụ emee, okpomọkụ ga-ebilite na ọtụtụ ihe ga-emeghachi omume na FKM, nke ga-emebi ngwá ọrụ na ndị ọrụ.
