Akụkọ - FKM Rubber vs PTFE: Kedu ihe kacha mma fluorinated |BESTFLON

Fluorine roba (FKM) bụ thermosetting elastomer, ebe polytetrafluoroethylene (PTFE) bụ thermoplastic.Ha abụọ bụ ihe nwere fluorinated, nke atom fluorine gbara ya gburugburu, nke na-eme ka ha na-eguzogide ọgwụ na-enweghị atụ.N'isiokwu a, TRP polymer ngwọta na-atụnyere ihe abụọ dị n'etiti FKM naPTFEiji chọpụta nke bụ ihe ikpeazụ fluorinated ma họrọ nke ikpeazụPTFE hose emeputa

Mmalite:

FKM: Ụgbọ elu n'oge Agha Ụwa nke Abụọ nwere nsogbu site na mwepu nke nitrile seals, nke na-enweghị obere ọrụ okpomọkụ achọrọ maka ngwa dị iche iche.Inertness kemịkalụ nke njikọ fluorocarbon pụtara na fluorinated elastomers, ma ọ bụ fluoroelastomer, bụ nkwubi okwu ebumpụta ụwa.Ya mere, rọba FKM malitere ịzụ ahịa na 1948

PTFE: Na 1938, ọkà mmụta sayensị DuPont Roy Plancott chọtara polytetrafluoroethylene na mberede.Plunkett jiri refrigerants nwale ma chekwaa ya na cylinders.N'ụzọ tụrụ ya n'anya, ikuku ndị a gbakọtara, na-ahapụ ihe na-acha ọcha waxy, nke na-adịghị emeghachi omume na ihe ọ bụla chemical bekee na ike idi oke okpomọkụ.DuPont debara aha mbụ nke PTFE ihe-ptfe na 1945

FKM roba: FKM rọba nwere njikọ carbon-fluorine siri ike, na-eme ka ọ bụrụ kemịkalụ dị ukwuu, na-eguzogide okpomọkụ na oxidation.FKM nwere ọnụọgụ carbon-hydrogen dị iche (njikọ nwere okpomọkụ na-esighị ike na nguzogide kemịkalụ), mana ọ ka nwere nguzogide kemịkalụ siri ike karịa ọtụtụ elastomer ndị ọzọ.

PTFE: Polytetrafluoroethylene bụ nke nwere agbụ nke carbon carbon, yana atom fluorine abụọ na atom carbon ọ bụla.Atọm fluorine ndị a na-agba gburugburu agbụ carbon ka ha mepụta mkpụrụ ndụ dị oke nke nwere njikọ carbon-fluorine siri ike yana usoro polymer, na-eme PTFE inert na ọtụtụ kemịkalụ.
