He aha ka mea i hana ʻia ai ka paipu ptfe?
Hoʻolauna huahana
1 、Ptfe paipuhe inoa ʻē aʻe no ka polytetrafluoroethylene, ʻo ka pōkole ʻōlelo Pelekania ʻo PTFE, (ʻike mau ʻia ʻo "Plastic King, Hara"), a ʻo ke ʻano kemika ʻo -(CF2-CF2)n-.Ua ʻike ʻia ʻo Polytetrafluoroethylene i ka makahiki 1938 e ka mea hoʻokalakupua ʻo Dr. Roy J. Plunkett ma DuPont's Jackson Laboratory ma New Jersey, USA I kona ho'āʻo ʻana e hana i kahi chlorofluorocarbon hou I ka hihia o ka mea hoʻohuihui refrigerant.ʻO nā huahana o kēia ʻano mea i kapa ʻia ʻo "non-stick coating";he mea polymer synthetic ia e hoʻohana ana i ka fluorine e pani i nā mana hydrogen a pau i ka polyethylene.Kūleʻa kēia mea i nā ʻakika, alkalis, a me nā mea hoʻoheheʻe organik like ʻole, a aneane hiki ʻole ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe a pau.I ka manawa like, aia ka PTFE i nā hiʻohiʻona o ke kūpaʻa wela kiʻekiʻe, a he haʻahaʻa loa kona friction coefficient, no laila hiki ke hoʻohana ʻia e like me ke ʻano o ka lubrication, a ua lilo nō hoʻi ia i mea uhi maikaʻi no ka papa o loko o nā ipu lāʻau ʻole. a me na paipu wai
Hoʻohana nui ʻia kēia mau huahana i nā huahana aʻe:
PTFE, FEP, PFA, ETFE, AF, NXT, FFR.
PTFE: PTFE (polytetrafluoroethylene) pani lāʻau ʻole hiki ke hoʻohana mau ʻia ma 260°C, me ka wela hoʻohana kiʻekiʻe o 290-300°C, haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, ʻaʻahu maikaʻi ke kūpaʻa a me ka paʻa kemika maikaʻi loa.
FEP: FEP (fluorinated ethylene propylene copolymer) ka uhi lāʻau ʻole hehee a kahe e hana i kahi kiʻiʻoniʻoni porous ʻole i ka wā e kuke ai.Loaʻa iā ia ke kūpaʻa kemika maikaʻi a me nā ʻano lāʻau ʻole.ʻO 200 ka wela hoʻohana kiʻekiʻe℃.
PFA: PFA (perfluoroalkyl compound) hoʻoheheʻe a kahe ʻole i ka wā e kuke ai e hana i kahi kiʻiʻoniʻoni porous ʻole e like me FEP.ʻO ka maikaʻi o ka PFA ʻo ia ka ʻoi aku ka kiʻekiʻe o ka hoʻohana ʻana i ka mahana o 260°C, ʻoi aku ka ʻoi aku o ka ʻoʻoleʻa a me ka paʻakikī, a kūpono loa ia no ka hoʻohana ʻana i nā noi anti-sticking a me ka pale kemika ma lalo o nā kūlana wela kiʻekiʻe.
ʻO ka PTFE (Polytetrafluoroethene) he mea polymer synthetic e hoʻohana ana i ka fluorine e pani i nā mana hydrogen āpau i ka polyethylene.Kūleʻa kēia mea i nā ʻakika, alkalis, a me nā mea hoʻoheheʻe organik like ʻole, a aneane hiki ʻole ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe a pau.I ka manawa like, loaʻa i ka ptfe tube nā hiʻohiʻona o ke kūpaʻa wela kiʻekiʻe, a he haʻahaʻa loa kona friction coefficient, no laila hiki ke hoʻohana ʻia no ka lubrication, a ua lilo hoʻi ia i mea uhi kūpono no nā woks maʻalahi a me nā paipu wai.Hiki ke hoʻohana ʻia no ka pale ʻana i ka corrosion pipeline, ke kiʻekiʻe a me ka haʻahaʻa haʻahaʻa haʻahaʻa, a me ka pale ʻana i ka corrosion.Hoʻohana ʻia i loko o nā kaiapuni koʻikoʻi e like me ka lubrication, engineering, electronics, nā mea uila, a me nā mokulele.
Nā hiʻohiʻona huahana
1、Ke kiʻekiʻe a me ka haʻahaʻa haʻahaʻa pale pale: liʻiliʻi ka hopena i ka mahana, ākea ākea ākea, pili i ka mahana -65 ~ 260 ℃.
2、 Non-sticky: ʻAʻole pili nā mea āpau i ke kiʻi PTFE.ʻO nā kiʻiʻoniʻoni lahilahi loa e hōʻike ana i ka hana maikaʻi ʻole.2. Heat kū'ē: PTFE uhi kiʻiʻoniʻoni maikaʻi loa wela a me ka haʻahaʻa wela kū'ē.Hiki iā ia ke pale i nā wela kiʻekiʻe a hiki i 300 ° C i ka manawa pōkole, a maʻamau hiki ke hoʻohana mau ʻia ma waena o 240 ° C a me 260 ° C.Loaʻa iā ia ke kūpaʻa wela nui.Hiki iā ia ke hana i nā mahana maloʻo me ka ʻole o ka embrittlement a ʻaʻole hoʻoheheʻe i nā wela kiʻekiʻe.
3, Sliding waiwai: PTFE uhi kiʻiʻoniʻoni i oi kiʻekiʻe coefficient o friction.Hoʻololi ke koena friction i ka wā e paheʻe ana ka ukana, akā aia ka waiwai ma waena o 0.05-0.15 wale nō.
4、Ka pale ʻana i ka wai: ʻAʻole pili ka ʻili o ka kiʻi ʻoniʻoni PTFE i ka wai a me ka ʻaila, a ʻaʻole maʻalahi ke hoʻopili i ka hopena i ka wā o ka hana ʻana.Inā he liʻiliʻi ka lepo, e holoi wale.Hoʻopau ʻia ka manawa pōkole, mālama i nā hola hana a hoʻomaikaʻi i ka pono hana.
5、Wear kū'ē: He maikaʻi loa ke pale ʻana ma lalo o ka ukana kiʻekiʻe.Ma lalo o kekahi ukana, loaʻa iā ia nā pōmaikaʻi ʻelua o ka pale ʻana a me ke keakea ʻole.
6、Ka pale ʻino: ʻAʻole ʻino ʻia ʻo PTFE e nā kemika, a hiki ke kū i nā ʻakika ikaika a pau (me ka aqua regia) a me nā mea hoʻoheheʻe ikaika koe wale nā metala alkali hoʻoheheʻe, fluorinated media a me ka sodium hydroxide ma luna o 300 ° C.Hiki i ke kuleana o ka mea ho'ēmi a me nā mea hoʻoheheʻe organik ke pale aku i nā ʻāpana mai nā ʻano corrosion kemika
waiwai kemika
1、Insulation: ʻAʻole pili i ke kaiapuni a me ke alapine, hiki i ke kūpaʻa leo ke piʻi i 1018 ohm·cm, liʻiliʻi ka poho dielectric, a kiʻekiʻe ka puʻupuʻu haʻihaʻi.
2、Ke kiʻekiʻe a me ka haʻahaʻa haʻahaʻa pale pale: liʻiliʻi ka hopena i ka mahana, ākea ākea ākea, pili i ka mahana -190 ~ 260 ℃.
3、Lubricating ponoʻī: Loaʻa iā ia ka liʻiliʻi liʻiliʻi o ka friction ma waena o nā plastics a he mea hoʻoluhi ʻaila maikaʻi ʻole.
4、ʻAʻole pili i ka ʻili: ʻaʻole hiki i nā mea paʻa paʻa ke pili i ka ʻili, he mea paʻa ia me ka ikehu ʻili liʻiliʻi.
5、Weather resistance, radiation resistance a me ka haʻahaʻa permeability: lōʻihi ka ʻike ʻana i ka lewa, ʻaʻole i loli ka ʻili a me ka hana.
6、Incombustibility: Aia ka helu helu palena o ka oxygen ma lalo o 90.
7、 Hoʻohana nui ʻia ʻo PTFE i nā ʻoihana e koi ana i ke kūpaʻa wela kiʻekiʻe a me ka viscosity kiʻekiʻe.Hiki ke hoʻohana ʻia ka super acid-fluoroantimonic acid no ka mālama ʻana
Wahi noi huahana
Hiki ke hana ʻia ka polytetrafluoroethylene ma ke kaomi ʻana a i ʻole extruding;hiki ke hana ʻia i kiʻiʻoniʻoni a laila ʻoki ʻia i loko o kahi lipine PTFE i hoʻopaʻa ʻia i ke kumu ke hoʻohana ʻia i nā uwea wela wela.Hoʻohana ʻia ia e hana i nā kaula alapine kiʻekiʻe a hana pololei i ka hoʻopuehu wai.Hiki ke hoʻohana ʻia no ka uhi ʻana, impregnation a i ʻole ka hana fiber.
Hoʻohana nui ʻia ka Polytetrafluoroethylene i nā ʻoihana e like me ka ikehu nuklea, ka pale aupuni, aerospace, electronics, uila, kemika, mīkini, mea kani, mika, kūkulu, textiles, metala ʻili lapaʻau, pharmaceuticals, mālama olakino, meaʻai, metallurgy a me ka hoʻoheheʻe ʻana, etc. nā mea hana, nā mea insulating, nā pale anti-stick, etc.
PTFE paipuLoaʻa iā ia nā waiwai piha maikaʻi loa, ke kūpaʻa wela kiʻekiʻe, ka pale ʻana i ka corrosion, non-stick, self-lubricating, nā waiwai dielectric maikaʻi loa, a me ka haʻahaʻa haʻahaʻa haʻahaʻa.Hoʻohana 'ia e like me ka 'enekinia plastics, hiki ke hana ia i loko o PTFE paipu, koʻokoʻo, kāʻei, papa, kiʻiʻoniʻoni, etc. maʻamau hoʻohana 'ia i ka corrosion-kui pipelines, ipu, pumps, valves, radar, kiʻekiʻe-frequency kamaʻilio lako, radio lako, radomes, etc. me nā koi hana kiʻekiʻe.Hoʻohui i kekahi mea hoʻopihapiha hiki ke kū i ka mahana sintering o polytetrafluoroethylene, hiki ke hoʻomaikaʻi maikaʻi ʻia kona mau mea mechanical.I ka manawa like, mālama ʻia nā waiwai maikaʻi ʻē aʻe o PTFE.Hoʻopiha ʻia nā ʻano like me ke aniani fiber, metala, metal oxide, graphite, molybdenum disulfide, carbon fiber, polyimide, EKONOL, etc. Hiki ke hoʻonui ʻia ke kumukūʻai o ka lole a me ka palena PV e 1000 mau manawa.
