Kedu ihe bụ PTFE?

Polytetrafluoroethylene (PTFE) bụ ụdị polymerized na tetrafluoroethylene dị ka monomer.Ọ nwere oke okpomọkụ na oyi na-atụ oyi na enwere ike iji ya ogologo oge na mwepu 180 ~ 260 º C. Ihe a nwere njirimara nke nguzogide acid, nguzogide alkali na iguzogide ihe mgbaze dị iche iche nke organic, ọ fọrọ nke nta ka ọ bụrụ ihe na-adịghị ike na ihe mgbaze niile.N'otu oge ahụ, polytetrafluoroethylene nwere njirimara nke nguzogide okpomọkụ dị elu, na ọnụ ọgụgụ esemokwu ya dị oke ala, ya mere enwere ike iji ya mee ihe maka mmanye, ma ghọọkwa mkpuchi dị mma maka nhicha dị mfe nke oyi akwa nke mmiri mmiri.PTFE na-ezo aka na mgbakwunye nke mkpuchi mkpuchi PTFE n'ime nkwonkwo roba EPDM nkịtị, nke na-acha ọcha.

Ọrụ nke PTFE

PTFE nwere ike n'ụzọ dị irè na-echebe roba nkwonkwo si ike acid, ike alkali ma ọ bụ elu okpomọkụ mmanụ na ndị ọzọ media corrosion.

Uru nke PTFE

• Nnukwu okpomọkụ na-eguzogide - arụ ọrụ okpomọkụ ruo 250 ℃
• Obere okpomọkụ na-eguzogide - ezigbo ígwè ọrụ ike;Ọbụna ma ọ bụrụ na okpomọkụ na-adaba na -196 ℃, elongation nke 5% nwere ike ịnọgide na-enwe.
• Nguzogide corrosion - n'ihi na ọtụtụ kemịkalụ na ihe mgbaze, ọ bụ inert na-eguzogide ọgwụ siri ike acid na alkalis, mmiri na iche iche organic solvents.
• Nguzogide ihu igwe - nwere ndụ ịka nká kacha mma nke plastik.
• Mmanya dị elu bụ ọnụọgụ esemokwu kacha ala n'etiti ihe siri ike.
• Na-abụghị nke adhesion - bụ nke kacha nta n'elu esemokwu n'ime ihe siri ike ma ghara ịkwado ihe ọ bụla.
• Na-adịghị egbu egbu - Ọ nwere inertia physiological, ọ nweghịkwa mmeghachi omume ọjọọ mgbe etinyere ogologo oge dị ka arịa ọbara na akụkụ ahụ.
• Igwe ọkụ eletrik - nwere ike iguzogide 1500 V elu voltaji.
