Ihe onwunwe uru nke PTFE osisi
Nnukwu nguzogide okpomọkụ-okpomọkụ ọrụ nwere ike iru 250 ℃.
Obere okpomọkụ na-eguzogide-nwere ezigbo igwe siri ike; ọbụlagodi ma ọ bụrụ na ọnọdụ okpomọkụ agbada -196 ℃, ọ nwere ike idobe 5% ịgbatị.
Nguzogide corrosion-Ọ naghị emetụta ọtụtụ kemịkal na ihe mgbaze, ọ nwere ike iguzogide acid siri ike na alkalis, mmiri na ihe mgbaze ihe dị iche iche.
Iguzogide ihu igwe-nwere ndụ ịka nká kacha mma n’etiti plastik.
Lubrication dị elu-bụ ọnụọgụ kacha nta nke esemokwu n’etiti ihe siri ike.
Enweghị nrapado-ọ bụ obere esemokwu dị n’etiti ihe siri ike ma ọ naghị arapara n’ihe ọ bụla. Ọnụ ọgụgụ nke ihe eji arụ ọrụ dị obere, naanị 1/5 nke polyethylene, nke bụ akụkụ dị mkpa nke elu perfluorocarbon. Tụkwasị na nke a, n’ihi na ike ikuku fluorine-carbon chain intermolecular dị oke ala, PTFE anaghị akwụgide.
Ndị na-adịghị egbu egbu-Ọ bụ ihe na-adịghị ahụkebe, ọ nweghịkwa mmeghachi omume ọjọọ dị ka arịa ọbara na akụkụ ahụ arụbara n’ime ahụ ruo ogologo oge.
Ngwongwo eletriki Polytetrafluoroethylene nwere obere ọnya ọkụ dielectric na ọnwụ dielectric n’ogologo oge, yana nwere nnukwu mgbada, ike resistivity na iguzogide arc.
Polytetrafluoroethylene nwere nguzogide radieshon na-adịghị mma (104 rad), ọ na-eweda ala mgbe ekpughere ya na radieshon dị elu, yana akụrụngwa eletriki na igwe nke polymer belatara nke ukwuu. Ngwa Polytetrafluoroethylene nwere ike ịmalite site na mkpakọ ma ọ bụ nhazi extrusion; enwere ike ịme ya ka mmiri gbasaa maka mkpuchi, mikpuo ma ọ bụ mee eriri. A na-eji Polytetrafluoroethylene eme ihe dị ka ihe na-eguzogide okpomọkụ dị elu na nke dị ala, ihe na-eguzogide corrosion, ihe mkpuchi, ihe mgbochi, na ihe ndị ọzọ na ike nuklia, ikuku, elektrọnik, eletriki, kemịkalụ, igwe, ngwa, mita, ihe owuwu, akwa, nri na ihe ndị ọzọ. ụlọ ọrụ.
Nguzogide ịka nká nke ikuku: nguzogide radieshon na obere ohere: ikpughe ogologo oge na ikuku, elu na arụmọrụ anaghị agbanwe agbanwe.
Enweghị ọkụ: Ndepụta oke ikuku oxygen dị n’okpuru 90.
Nguzogide acid na alkali: anaghị agbaze na acid siri ike, alkalis siri ike na ihe mgbaze organic.
Nguzogide oxidation: na -eguzogide corrosion site na nnukwu oxidants.
Acidity: Nnọpụiche.
Ngwongwo igwe nke PTFE dị nro. Nwere ume dị elu nke ukwuu.
Polytetrafluoroethylene (F4, PTFE) nwere usoro ọmarịcha arụmọrụ: nguzogide oke okpomọkụ-ogologo oge iji okpomọkụ nke 200 ~ 260 ogo, nguzogide dị ala-ka dị nro na -100 degrees; nguzogide corrosion na-eguzogide aqua regia na ihe mgbaze ihe ọkụkụ niile; Iguzogide ihu igwe-ndụ kacha mma ịka nká na plastik; mmanu mmanu di elu-ya na ogbara onu ogugu nke esemokwu (0.04) na plastik; enweghị nrapado-yana obere mgbali elu dị elu na ihe siri ike na-ejikọtaghị ihe ọ bụla; adịghị egbu egbu-ya na inertness physiological; Ọmarịcha akụrụngwa eletriki, ọ bụ ezigbo ihe mkpuchi klaasị C.
