PTFE paipuUa hoʻohana mua ʻia i ka ʻoihana automotive a lilo koke i kaulana.ʻOi aku ka maikaʻi o nā hose i hana ʻia mai ka polytetrafluoroethylene ma mua o ka hose rubber i nā noi kaʻa ma muli o kona loaʻa kālā kiʻekiʻe a me kāna hana maikaʻi loa, no laila ke piʻi nei kā lākou hoʻohana ʻana i nā kaʻa.
He aha ka PTFE hose?
ʻO ka hose PTFE he paipu i haku ʻia me kahi lining PTFE i loko a me kahi ʻāpana i hoʻopaʻa ʻia i waho me ke ʻano he uhi pale.Ua like ka PTFE liner me kahi paipu PTFE me kahi uhi pale o waho, e hoʻonui ana i kona kūpaʻa paʻakikī, e like me ka hoʻohana ʻana i nā kaʻa no ka hose PTFE.
He aha nā waiwai o ka hose PTFE?
Hiki ke ho'ohana 'ia no ka nui o na wahie

Hose wahie laina PTFE - nā ʻano:
Pupuu wahie PTFE wahine
ʻO ke kumu hose no ka wahine puʻupaʻaPTFE wahie paipuhana ʻia me 100% PTFE resin me ka ʻole o ka puaʻa a i ʻole nā mea hoʻohui.
Hoʻokaʻawale (Ati-static)PTFE wahie paipu
Statically dissipative a i ʻole conductive piha no ka hoʻopau ʻana i nā hoʻopiʻi static e pili ana i ka hoʻoili ʻana o ka wai.No ka holo ʻana me E85 a me Ethanol, a i ʻole Methanol Fuel, pono pono ka conductive PTFE i loko.
Hose PTFE no ka wahie - nā koho:
Hose wili ʻia ʻo PTFE me ka papa SS hoʻokahi - ʻO kekahi o nā paipu wahie PTFE kaulana loa
ʻO ka hose wili PTFE me ka papa SS pālua - E hoʻonui i ke kaomi no kekahi mau noi
ʻO ka hose wili ʻia ʻo PTFE me ka papa SS a me ka uhi Nylon ʻeleʻele - Pale maikaʻi i ka papa kila kila a me ke kūpaʻa abrasion
ʻO ka hose i hoʻopaʻa ʻia ʻo PTFE me ka papa SS hoʻokahi a me ka uhi ʻana o PVC - Pale maikaʻi i ka papa kila kila a hoʻohālikelike ʻia i kāu kaʻa.
Ke hoʻohālikelike ʻia me ka hose wahie rubber, no ke aha e koho aiPTFE wahie paipu?
ʻO nā laina wahie PTFE he mea hoʻololi maikaʻi loa ia no ka hose rubber.Me ka hana pono a me ka hale, hiki iā lākou ke lōʻihi loa a maʻalahi loa e hoʻokomo i loko o ka ʻōnaehana.ʻOiai ʻaʻole lākou e hāʻawi i ka laulā elastic like i hana ʻia me ka lāʻau lapaʻau, kūpaʻa loa nā hoses PTFE i ka hapa nui o nā kemika, a ʻaʻole lākou e hoʻokuʻu pinepine i ka uahi, he mea nui ia no kēlā me kēia ʻano wahi i hoʻopaʻa ʻia.ʻO ke kūpaʻa kemika ʻo ia hoʻi, ʻoi aku ka lohi o ka hose PTFE ma mua o nā paipu kīpē.
ʻOi aku ka haʻahaʻa o ka ʻili o ka PTFE ma mua o ka ʻōpala, ʻo ia ka mea e hiki ke hoʻomaikaʻi ʻia ke kahe kahe ma o ka hoʻohana ʻana i kahi hose PTFE.ʻOiai ua maʻalahi ka hoʻoheheʻe ʻia o ka lāʻau i nā wela wela, ʻaʻole kūpaʻa ʻo PTFE i nā wela kiʻekiʻe, e lilo ia i koho kūpono no ka hose wahie i ke kaʻa heihei.
ʻO ka mua, kaPTFE paipuhana ia ma ke ʻano he pale mahu e pale ai i nā ʻala ʻaila mai ka hū ʻana i loko o ka hale kaʻa a hale kūʻai a ʻā paha ke hoʻomaha kāu holo.
ʻO ka lua, ʻo ka hose i hoʻopaʻa ʻia i ka PTFE ke kūpaʻa kiʻekiʻe kiʻekiʻe a kākoʻo i kahi pūʻulu o nā wai kaʻa, ʻaʻole hiki ke hana me ka ʻōpala maʻamau.ʻO ka mea maʻamau ka loaʻa ʻana o ka ethanol i ka ʻaila i hui ʻia.Hiki ke hoʻoheheʻe ʻia nā puʻupuʻu maʻamau i ka wā e hoʻopili ai lākou me kēia ʻaila, a hiki i kahi e hoʻomaka ai e kahe a i ʻole e hoʻoheheʻe i ka wahie-he mea weliweli loa ia.
ʻO ke kolu, he kiʻekiʻe loa ka wela o ka hose laina PTFE-ʻoiaʻiʻo, ʻo ka pae wela hana o ka hose i kūʻai ʻia e kā mākou pahu wahie he -60 degere Celsius a +200 degere Celsius.He kūpono loa ia e wehe i ka paipu wai ma kāu kaʻa haʻuki.
ʻO ka hā, ʻo kā mākou wahie PTFE hose he hana kiʻekiʻe loa, e hōʻoia hou e hiki iā ʻoe ke hoʻohana ia no nā ʻano o nā noi automotive.He kūpono ka nui AN6 no 2500PSI, kūpono ka nui AN8 no 2000psi-ʻoiai no nā noi koi nui loa, ua lawa ke kaomi.
He aha ka laina wahie e pono ai ʻoe e holo me E85 a me ka ethanol, a i ʻole ka wahie methanol?
ʻO ka hoʻohana ʻana i nā wahie ethanol a me ka methanol ua lilo i mea kaulana loa i nā makahiki i hala iho nei, ʻoi aku ka nui me ka piʻi ʻana o nā ʻenekini kiʻekiʻe-horsepower turbocharged supercharged.Ua hōʻike ʻia ʻo E85 a i ʻole ethanol he wahie kūʻai kūpono e hiki ke hāʻawi i nā noi koi me ka helu octane a me ka mana mana.Eia kekahi, hiki iā ia ke hana i kahi hopena hoʻomaha i ka ea intake.
He mea ʻino naʻe ka ethanol, i kekahi manawa e hana ia i mea e like me ka gel, a hiki ke hoʻopōʻino i nā ʻāpana ʻōnaehana wahie, inā ʻaʻole e hoʻopilikia ʻia e ka ʻaila a me ke kinoea heihei.
Pono e hoʻohana i kahi kānana wahie kūikawā.ʻOiaʻiʻo, pono ʻoe e hōʻoia i ke kūpono o kāu pauma wahie, akā pehea ka laina wahie?
Hiki ke hāʻawi ʻia ka hose PTFE me ke kila kila a me ka uhi ʻeleʻele.Ke hoʻohana nei kēia ʻano conductive PTFE i kahi wili o waho a me kahi liner PTFE i loko, ka mea kūpaʻa loa i nā mea kemika a me ka decomposition thermal.He mea nui ka uea conductive e hoʻohana a noʻonoʻo i ke koho ʻana i ke koho PTFE, no ka mea, ʻo ka hoʻopiʻi electrostatic i hana ʻia e ke kahe wahie e arc / puhi maoli a hoʻoiho i ka hoʻopiʻi, ka mea e hana ai i ke ahi.
ʻOi aku ka paʻakikī o ka hui ʻana o PTFE, akā ʻaʻole maʻalahi kona ola e ka mahana a me ke kaomi.He koho maikaʻi loa ia no nā wahie corrosive, a me nā laina hoʻokele mana, nā laina aila turbine, a me nā mea ʻē aʻe.
