Ka ọ dị ugbu a, a na-ekewa ihe mkpuchi eriri USB nke a na-eji na-emepụta eriri na ụzọ atọ: PE, PVC, na XLPE.Ihe ndị a na-ewebata ọdịiche dị n'etiti ihe mkpuchi PE, PVC, na XLPE ejiri na eriri.
Explanation nke nhazi na njirimara nke ihe mkpuchi USB
PVC: Polyvinyl chloride, polymer kpụrụ site na polymerization efu nke vinyl chloride monomers n'okpuru ọnọdụ ụfọdụ.Ọ nwere njirimara nke nkwụsi ike, nkwụsị acid, nkwụsị alkali, nkwụsị nke corrosion, na ịka nká, a na-ejikarị ya eme ihe na ihe ụlọ, ihe ndị dị mkpa kwa ụbọchị, pipeline na ọkpọkọ, wires na cables, na ihe mkpuchi.A na-ekewa ya n'ime nro na nke siri ike: a na-ejikarị ndị dị nro na-emepụta ihe nkwakọ ngwaahịa, ihe nkiri ugbo, wdg, ma na-eji ya eme ihe na-emepụta waya na eriri mkpuchi eriri, dị ka eriri ọkụ polyvinyl chloride nkịtị;ebe ndị siri ike na-ejikarị eme ọkpọkọ na efere.Ihe kachasị dị n'ime ihe onwunwe polyvinyl chloride bụ ire ọkụ, ya mere a na-eji ya eme ihe n'ọtụtụ ebe na mgbochi ọkụ ma bụrụ otu n'ime ihe ndị a na-ejikarị eme ihe maka ọkụ ọkụ na eriri ọkụ na-eguzogide ọkụ.
PE: Polyethylene bụ resin thermoplastic mere site na polymerization nke ethylene.Ọ bụ ihe na-adịghị egbu egbu na nke na-adịghị emerụ ahụ, nwere ezigbo nguzogide okpomọkụ dị ala, ma nwee ike iguzogide mmebi nke ọtụtụ acid na alkalis, ma nwee ezigbo mkpuchi ọkụ eletrik.N'otu oge ahụ, n'ihi na polyethylene nwere àgwà nke na-abụghị polarity, ọ nwere àgwà nke obere ọnwụ na elu conductivity, n'ihi ya, a na-ejikarị eme ihe dị ka ihe mkpuchi maka eriri voltaji na eriri.
XLPE: Polyethylene jikọtara cross bụ ụdị ihe polyethylene dị elu mgbe mgbanwe gasịrị.Mgbe emeziwanye ya, akụrụngwa anụ ahụ na kemịkalụ ya ka mma nke ukwuu ma e jiri ya tụnyere ihe PE, ma n'otu oge ahụ, a na-emeziwanye ogo nguzogide okpomọkụ ya.Ya mere, wires na eriri nke ejiri ihe mkpuchi mkpuchi polyethylene na-ejikọta ya nwere uru na eriri ihe mkpuchi polyethylene na-enweghị ike dakọtara: ịdị arọ dị arọ, ezigbo okpomọkụ na-eguzogide, nkwụsị nke corrosion, dịtụ nnukwu mkpuchi mkpuchi, wdg.
E jiri ya tụnyere polyethylene thermoplastic, mkpuchi XLPE nwere uru ndị a:
1 Mmelite nrụrụ okpomọkụ, ihe arụrụ arụ arụrụ arụ na oke okpomoku, nkwụsi ike mgbawa gburugburu ebe obibi ka mma yana nguzogide ịka nká.
2 emelitere chemical kwụsie ike na ihe mgbaze eguzogide, belata oyi eruba, ihu ọma nọgidere na-enwe mbụ eletriki Njirimara, ogologo oge na-arụ ọrụ okpomọkụ nwere ike iru 125 ℃ na 150 ℃, cross-jikọrọ polyethylene mkpuchi mkpuchi wires na cables, nakwa mma mkpụmkpụ-circuit ibu ikike, ya. obere oge na-ebu okpomọkụ nwere ike iru 250 ℃, otu ọkpụrụkpụ nke wires na cables, cross-jikọrọ polyethylene ugbu a ibu ikike bụ ukwuu ukwuu.
3 XLPE mkpuchi wires na eriri nwere ọmarịcha igwe, mgbochi mmiri na ihe mgbochi radieshon, yabụ a na-eji ha eme ihe.Dị ka: eriri njikọ dị n'ime nke ngwa eletriki, ndị na-eduzi moto, ndị na-enye ọkụ, wires akara akara mgbaama ụgbọ ala dị ala, wires locomotive, wires ụzọ ụgbọ oloko na eriri, eriri nchekwa gburugburu ebe obibi, eriri mmiri, eriri ọkụ nuklia, wires TV nwere nnukwu voltaji. , X-RAY na-agbapụ wires voltaji dị elu, na eriri nnyefe ike na eriri na ụlọ ọrụ ndị ọzọ.
Ọdịiche dị n'etiti ihe mkpuchi USB PVC, PE, na XLPE
PVC: okpomọkụ dị ala na-arụ ọrụ, ndụ ịka nká dị mkpụmkpụ, obere ikike nnyefe, ikike ibufe obere, yana nnukwu anwụrụ ọkụ na ihe egwu gas na-agba ọkụ.Ngwaahịa izugbe na ụlọ ọrụ waya na eriri USB, ezigbo anụ ahụ na akụrụngwa, arụmọrụ nhazi dị mma, ọnụ ala na ọnụ ahịa ire ere.Ma o nwere halogens, na ojiji n'ọbọ bụ nke kasị ukwuu.
PE: Njirimara eletrik mara mma, yana uru niile nke PVC a kpọtụrụ aha n'elu.A na-ejikarị ya na mkpuchi waya ma ọ bụ eriri USB, mkpuchi ahịrị data, obere dielectric na-adị ala, dabara adaba maka ahịrị data, ahịrị nzikọrịta ozi, yana mkpuchi isi eriri kọmpụta dị iche iche.
XLPE: Ihe fọrọ nke nta ka ọ bụrụ PE na ihe eletriki eletrik, ebe okpomọkụ na-arụ ọrụ ogologo oge dị elu karịa PE, ihe ndị na-emepụta ihe dị mma karịa PE, na nkwụsị nke ịka nká dị mma.Ụdị ọhụrụ nke ngwaahịa enyi na gburugburu ebe obibi nwere ezigbo nguzogide okpomọkụ na gburugburu ebe obibi, plastik thermosetting.A na-ejikarị na waya eletrọnịkị na ebe nwere nnukwu nguzogide gburugburu ebe obibi chọrọ.
Ọdịiche dị n'etiti XLPO na XLPE
XLPO (polyolefin jikọtara cross): EVA, obere anwụrụ ọkụ na halogen na-enweghị halogen, njikọ njikọ radieshon ma ọ bụ vulcanized roba njikọ olefin polymer.Okwu izugbe maka klas nke resin thermoplastic nwetara site na polymerizing ma ọ bụ copolymerizing α-olefins dị ka ethylene, propylene, 1-butene, 1-pentene, 1-hxene, 1-octene, 4-methyl-1-pentene, na ụfọdụ cycloolefins. .
XLPE (polyethylene jikọtara cross): XLPE, polyethylene na-ejikọta ya, njikọ njikọ silane ma ọ bụ njikọ njikọ kemịkalụ, bụ resin thermoplastic mere site na polymerization nke ethylene.Na ụlọ ọrụ, ọ na-agụnye copolymer nke ethylene na obere ego nke α-olefins.
