Polytetrafluoroethene,khutsufatso:PTFE
Letšoao: PTFE, tetrafluoroethylene, morena oa polasetiki, F4.
Melemo ea PTFE
PTFEke lipolasetiki tse khethehileng tsa boenjiniere, hajoale ke lisebelisoa tse sa jeng, tse tsejoang e le "morena oa polasetiki".Likarolo tse ka sehloohong ke ho hanyetsa mocheso o phahameng le o tlaase, ho hanyetsa kutu, ho pata ho hoholo, ho hanyetsa botsofali, ho itlotsa.
E sebelisoa sebakeng sa sefofane, lisebelisoa tsa elektroniki le lisebelisoa tsa motlakase, indasteri ea lik'hemik'hale, mechini le lisebelisoa, lijo le bongaka, lipompo, li-valve le liphaephe, likoloi le likepe, li-compressor tsa moea, joalo-joalo, 'me e fetohile sesebelisoa sa bohlokoa ho rarolla mahlale a mangata a bohlokoa mehleng ea kajeno indasteri.
PTFE molek'hule inert F liathomo shielding le ho sireletsa CC bond, le CF bonding eneji ke haholo-holo tsitsitseng, molek'hule ketane ke ho le thata ho timetsoa, ke mohaho o tsitsitseng haholo.Sebopeho sena sa limolek'hule se boetse se hlalosa litšobotsi tse latelang tse babatsehang tsa PTFE.
Corrosion resistance:Ho phaella ho lirafshoa tsa alkali tse qhibilihisitsoeng le metsoako e 'maloa e kang all-alkane hydrocarbons ka holimo ho likhato tse 300 tsa Celsius, e hanyetsana le ho bola ha nako e telele ke lik'hemik'hale leha e le life tse ling.
Ho hanyetsa mocheso o phahameng le o tlase: e ka sebelisoa nako e telele ho -60+260℃.
Lubrication e phahameng:karolo e nyenyane ka ho fetisisa ea khohlano har'a thepa e tiileng, esita le leqhoa le ke ke la bapisoa le lona.
Ho se khomarele:tsitsipano e nyane ka ho fetisisa ea bokaholimo har'a lisebelisoa tse tiileng, ha e khomarele ntho efe kapa efe.
Maemo a Leholimo:Bophelo bo bolelele ka ho fetisisa ba botsofali har'a li-plastiki.
Non-toxicity:thepa e ka sebelisoa e le methapo ea mali ea maiketsetso, e seng chefo le e seng allergic le tse ling tse mpe, bakeng sa lijo le meriana kereiti ya thepa.
Lintho tsa insulating:filimi e teteaneng joaloka koranta e lekane ho hanela motlakase o phahameng oa 1500V.
Ho feta moo, PTFE e boetse ha e na ho monya mongobo, e sa cheng, 'me e phahame haholo ho oksijene, leseli la ultraviolet.
Mefokolo ea PTFE
Le ha PTFE e na le ts'ebetso e felletseng e felletseng, empa matla a tlase a mochini, matla a maholo a katoloso ea mela, ho hanyetsa ho roala ho futsanehileng, khanyetso e mpe ea creep, conductivity e mpe ea mocheso le mefokolo e meng.Ka matla a mochine le maemo a mang a rarahaneng, a kang ho sebelisoa indastering ea ho tiisa li-valve le moeli oa eona oa sebele oa tšebeliso e sireletsehileng ea mocheso ka kakaretso o ka hare ho -70 ~ +150 ℃.E le ho hlōla mefokolo ena, resin ea PTFE e ka tlatsoa ka lisebelisoa tse matlafatsang ho ntlafatsa thepa ea mochine, e le ho atolosa boholo ba tšebeliso ea thepa ea eona.
Kenyelletso ea thepa ea mebala ea PTFE
Mmala oa mantlha oa PTFE o bosoeu ba lebese, athe PTFE e mebala ke hobane lisebelisoa tsa motheo tsa PTFE li tletse lisebelisoa tse thusang.Lisebelisoa tsa tlatsetso li ka aroloa ka mekhahlelo e 'meli ho latela ts'ebeliso: sesebelisoa sa ntlafatso le sesebelisoa sa phofo sa mebala.
Sehlopha sa moemeli oa phofo ea mebala: se tletse phofo ea 'mala ho PTFE, e ka ba e ntšo, e mosehla, e khubelu, e tala, e putsoa, joalo-joalo.Mobala oa phofo ke feela ho fetola 'mala oa PTFE, karo-karolelano ea ho tlatsa ke chelete e nyane kahoo phello ea ts'ebetso ea pele ea PTFE e ka hlokomolohuoa.Ka khopolo, moemeli oa phofo ea 'mala o lokela ho khona ho ama botsitso ba lik'hemik'hale tsa PTFE, ho kenya letsoho, matla a ho tsitsa le lisebelisoa tse ling tsa mechine.Ka hona, liketsahalo tse ling tse khethehileng li lokela ho elelloa.PTFE e mebala e kopana le litlhoko tsa bareki ba nang le litlhoko tsa mebala e bonahalang.
Ho reka li-tubing tse nepahetseng tsa PTFE ha se feela ka ho khetha litlhaloso tse fapaneng bakeng sa lits'ebetso tse fapaneng.Ho feta ho khetha moetsi ea ka tšeptjoang.BesteflonFluorine plastic Industry Co., Ltd. e sebetsa ka ho khetheha tlhahisong ea boleng bo holimoLithapo tsa PTFEle li-tubes ka lilemo tse 20.Haeba ho na le lipotso le litlhoko tsa ptfe tube, ka kopo ikutloe u lokolohile ho ikopanya le rona bakeng sa likeletso tse ling tsa litsebi.
