Phaephe ea Polytetrafluoroethylene (PTFE) ke sehlahisoa se feto-fetohang haholo se ka fanang ka mefuta e mengata ea lits'ebetso liindastering tse fapaneng. E etsoa ka mokhoa oa ho ntša pente. Phaephe ea PTFE e entsoeng ka ho ntša pente e tenyetseha. E ka etsa liphaephe tsa PTFE tse nang le bophara ba ka hare bo bonyenyane ba 0.3 mm ho isa ho 100 mm le botenya ba lebota bo bonyenyane ba 0.1 mm ho isa ho 2 mm.Leropo la PTFEE na le botsitso bo botle ba lik'hemik'hale, e ka mamella li-acid tsohle tse matla, li-alkali tse matla, li-oxidant tse matla, 'me ha e sebelisane le li-solvents tse fapaneng tsa tlhaho. E ka sebelisoa ka tloaelo ka hare ho -60℃～+260℃, ka khanyetso e tšepahalang le e ntle ea ho bola. E ka tsamaisa khase e matla e senyang le mokelikeli mochesong o phahameng. Ho phaella moo, ka mor'a ho phekoloa mochesong o phahameng oa 260℃ bakeng sa 1000h, thepa ea eona ea mechini ha e na phetoho e kholo. PTFE e na le ntlha ea khohlano e tlase haholo, ke thepa e ntle ea ho loantša khohlano, e itlotsang, coefficient ea eona ea khohlano e sa fetoheng e ka tlase ho coefficient ea khohlano e matla, kahoo bearing e entsoeng ka eona e na le melemo ea khanyetso e tlase ea ho qala le ts'ebetso e tsitsitseng. Hobane PTFE ha e polar, e hanela mocheso ebile ha e monye. E boetse e na le khanyetso e ntle ea botsofali, ha e khomarele ebile ha e chese. Sena se ke ke sa nkeloa sebaka ke liphaephe tse ling.
Selelekela se latelang ke tšebeliso ea hose ea PTFE liindastering tse fapaneng:
1. Indasteri ea lik'hemik'hale
Hobane li na le khanyetso e phahameng ea lik'hemik'hale ho hoo e ka bang lik'hemik'hale tsohle,Phaephe ea PTFEke khetho e ntle indastering ea lik'hemik'hale. Ho kenyeletsoa le indasteri ea semiconductor. Ts'ebetso ea sejoale-joale ea tlhahiso ea semiconductor e hloka ho lekanya ka mokhoa o sireletsehileng le ho tsamaisoa ha metsi a senyang (li-acid le alkali). Tsena li tla senya phaephe ea ho tlisa thepa haholo ka nako e khuts'oane.
2. Indasteri ea bongaka
Thepa e ikhethang ea liphaephe tsa PTFE e boetse e kenyelletsa sebopeho sa bokaholimo bo bonolo ho bo hloekisa. Lilemong tse leshome tse fetileng, liphaephe tsa PTFE li 'nile tsa sebelisoa haholo lisebelisoa tsa bongaka. Ka lebaka la khohlano e tlase ea tube ea PTFE, sena se bolela hore bokaholimo ba eona bo boreleli haholo 'me bo ke ke ba koahela kapa ba thusa libaktheria ho hola. Har'a tsona, liphaephe li sebelisoa bakeng sa ho kenya liphaephe, li-catheter, li-pipettes le li-endoscopes. E boetse e etsa lisebelisoa le lisebelisoa tse fapaneng, tse kang liphaephe tsa drain, li-ventilator, masale, rabara ea apole, liatlana le lisele tse ling tsa maiketsetso. Ho phaella moo, lisebelisoa tse ngata tse sebetsang tse sebelisoang ke lingaka tlhahlobong ea lik'hemik'hale tsa batho le tsona li entsoe ka thepa ea PTFE.
3. Indasteri ea lifofane
Liphaephe tsa PTFE ke li-fluoropolymer tse sa cheseng. Khokahano ea tsona e tlase e li lumella ho sebetsa tlas'a mocheso o feteletseng le khatello. Ke ka lebaka leo liphaephe tsena li sebelisoang ke indasteri ea lifofane ho phuthela lithapo le likhoele.
4. Indasteri ea likoloi
Lienjeneng tsa likoloi, liphaephe tsa oli tsa boleng bo holimo tse entsoeng ka PTFE li sebelisoa bakeng sa mouoane oa mafura le lireile tsa mafura. Hona joale, liphaephe tsa brake tse 'marakeng kaofela ke likopano tsa liphaephe tsa brake tse nang le manonyeletso. Ho ea ka mefuta e fapaneng ea liphaephe tsa likoloi, e arotsoe ka liphaephe tsa brake tsa hydraulic, liphaephe tsa brake tsa pneumatic le liphaephe tsa brake tsa vacuum. Ho ea ka thepa ea eona, e arotsoe ka phaephe ea brake ea PTFE, phaephe ea brake ea rabara le phaephe ea brake ea nylon. Phaephe ea brake ea rabara e na le melemo ea matla a ho hula le ho kenngoa habonolo, empa bothata ke hore bokaholimo bo kotsing ea ho tsofala kamora tšebeliso ea nako e telele. Tabeng ea mocheso o tlase, matla a ho hula a phaephe ea brake ea nylon aa fokola, haeba e angoa ke matla a kantle, ho bonolo ho e roba. Leha ho le joalo,Tube ea PTFE ea Besteflone na le litšobotsi tsa ho hanyetsa mocheso o phahameng le mocheso o tlase, ho hanyetsa khatello e phahameng, ho hanyetsa ho khoholeha le ho hanyetsa ho bola, e leng se etsang hore e be le bophelo bo bolelele ba tšebeletso 'me ha e hloke ho nkeloa sebaka khafetsa. E ka lokisa mefokolo ea lisebelisoa tse ling tse peli.
5. Indasteri ea motlakase
Liphaephe tsa PTFE li na le litšobotsi tse ntle tsa motlakase. Li na le litšobotsi tse phahameng tsa dielectric tse sa fetoheng le tse nang le tahlehelo e tlase maemong a mangata a maqhubu. Ka hona, liphaephe tsa PTFE li sebelisoa e le thepa ea boleng bo holimo, e sireletsang mocheso bakeng sa lithapo le likhoele, hammoho le lisebelisoa tsa ho futhumatsa tsa motlakase le li-sensor tsa mocheso. Indastering ea motlakase, ho koahela lithapo le likhoele, ho sebelisoa liphaephe tsa PTFE tsa boleng bo holimo, tse ka mamellang mocheso o phahameng le ho sireletsa lithapo ho sehiloeng leha e le hofe. Ho phaella moo, liphaephe tsena li tla ka mebala e fapaneng ho thusa ho khetholla lithapo ka tlung kapa ofising.
6. Indasteri ea lijo
Ka lebaka la litšobotsi tsa eona tse bonolo ho li hloekisa le tse sa khomareleng, liphaephe tsa PTFE polytetrafluoroethylene li ka sebelisoa indastering ea lijo. Haholo-holo, liphaephe tse entsoeng ka PTFE e sa tlatsoang li loketse ka lebaka la ho se nke lehlakore ha tsona 'meleng' me li latela litataiso tsa US Food and Drug Administration. Ka hona, ho pakiloe hore ha e na kotsi ha e kopana le polasetiki le mofuta ofe kapa ofe oa lijo. Ka hona, liphaephe tsa PTFE hangata li sebelisoa mechineng ea kofi ea setso. Ho phaella moo, ho sebelisoa liphaephe tsa spaghetti tse bitsoang tsa kamore e le 'ngoe kapa tsa likamore tse ngata le liphaephe tse fokotsang mocheso. Lihlahisoa tsa PTFE li ka hloekisoa ka ho sebelisa mekhoa eohle e tloaelehileng.
7. Indasteri ea masela
Phetisetso ea lik'hemik'hale liphaepheng tse sebelisoang indastering ea masela e ka baka mafome. Ka hona, e le ho qoba bothata bona, ho sebelisoa tube ea TPFE, 'me ho etsoa sekoahelo sa PTFE holim'a rola ea masela.
Indasteri ea Khatiso ea 8.3D
Khatisong ea 3D, khoele e lokela ho fetisetsoa ho nozzle ea khatiso e lokelang ho etsoa ka mocheso o phahameng. Kaha tube ea PTFE e na le coefficient ea mocheso o phahameng le thepa e sa khomareleng, e thusa ho thellisa thepa habonolo ho tsoa nozzle, kahoo ke polymer e lakatsehang ka ho fetisisa indastering ea khatiso ea 3D.
Tlhaho ea PTFE e seng ea alkaline e e lumella ho sebelisoa indastering ea lik'hemik'hale, moo phetiso ea maro a bonolo haholo e leng ntho e tloaelehileng. Zhongxin Fluorine plastic Industry Co., Ltd. E ikhethile ka tlhahiso ea lihose tsa PTFE tsa boleng bo holimo ka lilemo tse 16
