Lipotso Tse Botsoang Khafetsa Mabapi le Tube ea PTFE bakeng sa Ts'ebetso ea Lik'hemik'hale
P1: Na lipeipi tsa PTFE li ka sebetsana le asiti ea hydrofluoric (HF)?
K: E. PTFE ke e 'ngoe ea thepa e fokolang haholo e ka sebetsanang ka mokhoa o sireletsehileng le asiti ea hydrofluoric ka bongata bo fihlang ho 49% le mocheso o fihlang ho 260°C. Ho fapana le tšepe e sa ruseng, khalase, le boholo ba polasetiki, PTFE ha e bontše ho senyeha ho ka lekanngoang ha e pepesehetse HF. Li-tube tsa rona tsa PTFE tsa sehlopha sa lik'hemik'hale li sebelisoa haholo lits'ebetsong tsa ho hlaba ha semiconductor le ho sila asiti moo HF e leng reagent ea mantlha.
P2: Mocheso o phahameng ka ho fetisisa oa ho sebetsa bakeng sa lipeipi tsa PTFE ts'ebetsong ea lik'hemik'hale ke ofe?
K: Liphaephe tsa PTFE li ka sebetsa ka ho tsoelang pele ho 200°C ntle le tahlehelo ea thepa ea mechini kapa khanyetso ea lik'hemik'hale. Ho pepesehela nako e khuts'oane ho fihlela ho 260°C hoa amoheleha. Ho fapana le liphaephe tsa rabara kapa tsa silicone tse senyehang mochesong o phahameng, PTFE e boloka botsitso ba eona ho pholletsa le mocheso oa eona o felletseng. Bakeng sa lits'ebetso tsa lik'hemik'hale tse sebetsang kaholimo ho 200°C, PTFE hangata ke eona feela khetho ea liphaephe tsa polymer e fumanehang.
P3: Li-tube tsa PTFE li nka nako e kae libakeng tsa ts'ebetso ea lik'hemik'hale?
K: Tlas'a maemo a tloaelehileng a ts'ebetso (ka har'a mocheso o lekantsoeng, khatello, le ho lumellana ha lik'hemik'hale), lipeipi tsa PTFE hangata li nka lilemo tse 5-10 kapa ho feta. PTFE ha e tsofale, ha e senyehe, kapa ha e tetebele ha nako e ntse e ea joalo ka mekhoa e meng ea rabara kapa polasetiki. Mekhoa ea mantlha ea ho hloleha ke tšenyo ea mechini (ho pshatla, ho kobeha ho feteletseng) kapa ts'ebetso ka ntle ho liparamente tse lekantsoeng. Libakeng tse ngata tsa lik'hemik'hale, lipeipi tsa PTFE li nka nako e telele ho feta lisebelisoa tseo li li sebeletsang.
P4: Na lipeipi tsa PTFE li ka sebelisoa bakeng sa lits'ebetso tsa lik'hemik'hale tse hloekileng haholo?
K: E. Li-tube tsa rona tsa PTFE tse hloekileng haholo li bontša maemo a tlase a ho ntša li-ion tsa tšepe le boleng bo tlase haholo ba ho ntša khabone ea organic (TOC). Li loketse ho tlisoa ha lik'hemik'hale tsa sehlopha sa semiconductor, phetisetso ea reagent ea sehlopha sa elektroniki, le litsela tsa mokelikeli oa lisebelisoa tsa tlhahlobo. Bakeng sa lits'ebetso tse hlokang boiteko bo boholo, re fana ka limaraka tse khethehileng tse hloekisitsoeng le tse pakiloeng.
P5: Na le fana ka lipeipi tsa PTFE tse thibelang ho fetoha bakeng sa tšebeletso ea tharollo e tukang?
K: E. Ha ho fetisoa ditharollo tse tukang tse kang acetone, ethanol, kapa toluene, ho bokellana ha tjhaja e sa fetoheng ho ka baka dikotsi tsa ho hotetsa. Diphaephe tsa rona tsa PTFE tse tsamaisang motlakase di na le khanyetso ya bokahodimo ya 10⁶–10⁹ ohms, e leng se qhalang motlakase o sa fetoheng ka polokeho. Diphaephe tsena di sebediswa haholo ditsamaisong tsa phetisetso ya tharollo, mela ya pente, le mesebetsi ya ho tlatsa meropa ya dikhemikhale.
P6: Nka hokela lipeipi tsa PTFE joang tsamaisong ea liphaephe tsa lik'hemik'hale?
K: Mekhoa e tloaelehileng ea khokahano e kenyelletsa: (1) Lisebelisoa tsa khatello — tse tsebahalang haholo bakeng sa lipeipi tse nyane ho isa ho tse mahareng tsa bophara; (2) Lisebelisoa tsa ho phatloha — bakeng sa ts'ebeliso e phahameng ea khatello; (3) Likhokahano tsa Flange — bakeng sa lipeipi tse bophara bo boholo; (4) Lisebelisoa tsa barb tse sutumelletsoang — bakeng sa lipeipi tse nang le khatello e tlase. Re boetse re fana ka lisebelisoa tsa tube tse kopantsoeng esale pele le likopano tsa hose. Khetho e itšetlehile ka khatello, bophara ba tube, le makhetlo a ho khaoloa.
P7: Na ho kenella ha lik'hemik'hale ho etsahala ka mabota a tube ea PTFE?
K: Maemong a mocheso le kgatello e tloaelehileng, PTFE e na le kganyetso e ntle haholo ho kenngwa ha dikhemikhale. Leha ho le jwalo, maemong a mocheso a phahameng (ka hodimo ho 200°C) ka dikhemikhale tse itseng tse nyane, ho kenngwa ha dikhemikhale ho ka etsahala ka nako e telele. Bakeng sa ditshebediso tsa bohlokwa tse kenyeletsang dikhemikhale tse nang le mocheso o phahameng kapa dikhemikhale tse chefo haholo, re kgothaletsa ho bewa ha diphaephe tse teteaneng tsa lebota ho fokotsa kotsi ya ho kenngwa ha dikhemikhale.
P8: Na lipeipi tsa PTFE li ka sebetsana le vacuum le khatello ts'ebetsong ea lik'hemik'hale?
K: E. Lipeipi tsa PTFE li ka sebetsana le tšebeletso e felletseng ea vacuum le khatello e ntle ho fihlela khatellong e lekantsoeng ea ts'ebetso bakeng sa boholo bo bong le bo bong. Bakeng sa ts'ebeletso ea vacuum, lipeipi tse teteaneng tsa lebota li khothaletsoa ho thibela ho putlama. Lipeipi tsa rona tsa PTFE tse nang le lebota le boima (botenya ba lebota ba 3mm+) li etselitsoe ka ho khetheha bakeng sa ho potoloha khatello/vacuum ka bongata lik'hemik'haleng tsa lik'hemik'hale le lits'ebetsong tsa ho qhala.
P9: Ke mangolo afe a netefatso le ditokomane tseo o ka fanang ka tsona?
K: Re fana ka setifikeiti sa taolo ya boleng ba ISO 9001:2015, ho latela melao ya FDA bakeng sa ho ikopanya le dijo/meriana, ho latela melao ya RoHS bakeng sa mebaraka ya Yuropa, le ditlaleho tsa diteko tsa mokga wa boraro (SGS) ha ho kopuwa. Ditlaleho tsa tlhahlobo ya ho tsamaellana le dikhemikhale di fumaneha bakeng sa mecha e itseng ya phatlalatso ha ho kopuwa.
P10: Bongata bo fokolang ba odara bakeng sa lipeipi tsa PTFE tsa sehlopha sa lik'hemik'hale ke bokae?
K: Bakeng sa boholo bo tloaelehileng, ha ho na odara e fokolang. Bakeng sa litlhaloso tse ikhethileng, MOQ e itšetlehile ka ho rarahana, hangata ho qala ho tloha ho limithara tse mashome. Re tšehetsa ka mafolofolo liodara tsa liteko tsa sehlopha se senyenyane e le hore u ka netefatsa sehlahisoa tšebeletsong ea hau ea 'nete ea lik'hemik'hale pele u itlama ho reka ka bongata.
