Ihe dị iche n'etiti Teflon na polytetrafalaoatene

PVDF bụ obere fluoridene, nke dị njọ karịa f4 na F46, na F46, na-eguzogide ọnọdụ okpomọkụ na obere nguzogide na-eguzogide (ọnụahịa ahụ dị ọnụ ala karịa F4 na F46).

PTFE (F4) bụ polytetraFooroorooroorooroaene, nke nwere ezigbo ọnọdụ okpomọkụ na iguzogide corrosion nke ọ bụla. Agba ahụ dị ọcha. A na-ejikarị ya maka ikpo ọkụ, valves, akàrà, mkpanaka, wdg.

FEP (F46) bụ polypperfluethylene proslene, agba dị transpomicent, na iguzogide ya na nke PTFE. A na-ejikarị ya maka nfuli mmiri na-ekpo ọkụ ma ọ bụ nfuli pọpụ. PFA Tetraflulluethylene-interluoooroooxy Vinyl Ether Poliorooroorooroorooroorooroorooroorooroorooroorooroutistic, soltuoologyl, na abụọ na-ejikwa abụọ iji bulie ọkụ na-eguzogide.

Ngwongwo kemịkal nke PFAFEPPTFE yiri nke ahụ, mana enwere ike iji naanị ogo 200, yana PTFE enweghị ike ịkpụzi.

A na-akpọ Teflon PolytetraFoorfuearfuearWlene na Bekee, nke a na-ezo aka na Teflon, PTFE, FAFL, PFA, ETFE

Ọtụtụ ụdị dị mkpa:

Teflon Ptfe:

Enwere ike iji polytetrathylenethylene) Enwere ike iji mkpuchi mkpuchi na-enweghị isi na 260 Celsius C, nke dị oke ọnụ ọgụgụ nke esemokwu na kemịkacha mma.

Teflon FEP:

FEP (igwe eleplenated etylene protoymener) na-enweghị mmachi akwa na-adịghị mma na-agbaze ma na-eto eto na-enweghị atụ n'oge achịcha. Ọ nwere ezigbo kemịkal na ihe ndị dị mma na-enweghị mkpanaka. Okpomoku kachasi nma bu 200 Celsius C

Teflon PFA:

PFA (perluooooooooooooologyyyyyy) dị ka FEP, agbazekwa ma na-asọpụta na-etolite na-enweghị atụ n'oge achịcha. Uru nke PFA bụ na ọ nwere okpomọkụ dị elu nke 260 Celsius C, nkwụsi ike na ihe isi ike, ma dịkwa mma maka mgbochi ịrapara na ngwa nguzogide n'okpuru ọnọdụ okpomọkụ dị n'okpuru ọnọdụ ọnọdụ okpomọkụ dị elu.

Teflon Esfe:

ETFE bụ Coploonene na TetraFooooroooporoothylene, onye kachasị sie ike na-enwe oke mkpuchi na-enwe ike iguzosi ike na-arụ ọrụ ruo 150 Celsius.
