A na-akpọ efere Tetrafluoroethylene dị ka eze plastik n'ọhịa nke plastik, na arụmọrụ ya adịghị arụ ọrụ site na plastik nkịtị, n'ihi ya, a na-ejikarị ya eme ihe n'ebe ndị nwere gburugburu ebe obibi siri ike, dị ka acid na alkali, mgbasa ozi na-emebi emebi na okpomọkụ dị elu.Yabụ, kedu uru nke bọọdụ PTFE?
Nke mbụ, ọ nwere nnukwu nguzogide okpomọkụ.N'ihe gbasara iji ihe mpempe akwụkwọ tetrafluoroethylene ugbu a, akụrụngwa nwere ike iru 232 Celsius C, na ọbụna okpomọkụ dị elu mgbe ọ laghachiri n'ime ụlọ nwere ike iru ihe dịka 150 Celsius C, na ojiji okpomọkụ dị oke.
Mpempe akwụkwọ PTFE nwere njirimara dielectric magburu onwe ya, ike dielectric pụtara ìhè na nguzogide arc, tangent dielectric dị ala, na nguzogide corona na-adịghị mma.Mpempe akwụkwọ tetrafluoroethylene nwere ezigbo nnabata na-abụghị mmiri, enweghị oxygen, UV na nguzogide ihu igwe.Ike tensile dị n'èzí nọgidere na-agbanweghị agbanwe ruo afọ atọ sochiri, naanị elongation belatara.Ihe nkiri Teflon na mkpuchi na-adaba na mmiri na gas n'ihi porosity ha dị mma.PTFE nwere ike dabara adaba maka ọnọdụ okpomọkụ n'etiti mwepu 190 degrees na 250 degrees.Ọ nwere ike ịdị ọkụ ma ọ bụ oyi na mberede, ma ọ bụ na-atụgharị na-ekpo ọkụ na oyi na-enweghị mmetụta ọ bụla.Na mgbakwunye na idozi nsogbu mmepụta kemịkalụ na mmanụ mmanụ, mpempe akwụkwọ tetrafluoroethylene nwekwara ike ịrụ ọrụ na ọgwụ na mpaghara ndị ọzọ.Enwere ọtụtụ ihe mkpuchi na ahịa taa, yana ngwaahịa gasket ma ọ bụ gasket.Na mgbakwunye, a na-ejikwa PTFE n'ọtụtụ ebe na ihe nwere akara akara, a na-ejikwa ya dị ka ihe mkpuchi Jinxining.Ọrụ nke mpempe akwụkwọ PTFE dị oke mma, n'ihi na mpempe akwụkwọ PTFE nwere nnukwu ọrụ, ngwaahịa dị iche iche, ma na-arụ ọrụ dị ukwuu na mpaghara dị iche iche na mpaghara mmetụta.Enwere ike ịhụ PTFE n'ebe niile na ndụ anyị.
Nke abuo, n'agbanyeghị ụdị kemịkal ọ bụ, n'agbanyeghị otú ọ na-emebi emebi, PTFE nwere ike iji isi mee ihe.Enwere ike ikwu na ọ bụrụ na mpempe akwụkwọ PTFE enweghị ike izute ihe ndị na-eguzogide corrosion, ọ dịghị ihe ọzọ plastik nwere ike iji mee ihe.Na mgbakwunye na nguzogide kemịkalụ ya magburu onwe ya, ihe eji arụ ọrụ ya dịkwa oke egwu, nke na-eme ka ọ dị mma maka ojiji n'oge nwere nnukwu swings na bends.
PTFE mpempe akwụkwọ na ọtụtụ-eji engineering plastik dị ka elu okpomọkụ 260 ℃, ala okpomọkụ -196 ℃, acid na alkali corrosion eguzogide, ihu igwe na-eguzogide na-abụghị toxicity.Enwere ike ịhụ PTFE na mmanụ ala, kemịkalụ, ahụike, eletrọnịkị na ọbụna ụlọ ọrụ nri.Ma efere PTFE bụ ihe na-egbu egbu ma nwee ezigbo mgbochi iyi, ọ bụ ihe mkpuchi dị mma.PTFE (Polytetrafluoroethylene, nke akpọrọ PTFE), nke a na-akpọkarị "mkpuchi na-adịghị mma" ma ọ bụ "ihe dị mfe na-adị ọcha".Nke a ihe onwunwe nwere àgwà nke acid na alkali iguzogide na iguzogide dị iche iche organic solvents, na ọ fọrọ nke nta insoluble ke niile mgbaze.N'otu oge ahụ, efere PTFE nwere njirimara nke nguzogide okpomọkụ dị elu na ọnụọgụ esemokwu dị oke ala.Na mgbakwunye na mmanye mmanye, usoro mmepụta nke mkpuchi efere PTFE aghọwo ihe mkpuchi dị mma maka nhicha dị mfe nke n'ime oyi akwa nke ọkpọ mmiri.
