Ukuthelekiswa kweeNtathu zeNgqungquthela yePowder yeFluorocarbon (ETFE, FEP, PFA): Iipropati kunye nezicelo

Zonke ziphantsi kweendidi ezibalulekileyo zeengubo ezisekelwe kwiTeflon. Ukusebenzisa iipropathi ze-fluoropolymers, zidlala indima yokukhusela efana nokuchasana nokugqwala, ukusebenza okungabambekiyo, kunye nokuchasana nobushushu obuphezulu kwimizi-mveliso nakwezinye iindawo. Nangona kunjalo, ezi zintathu zahlukile kubushushu bokusebenza, ukusebenza kokwambathisa, kunye neemeko zesicelo. Iiyantlukwano ezithile zezi zilandelayo:

1. ETFE Thermoplastic Fluorocarbon Powder Coating

• Ukusebenza okungundoqo: Yenye yeentlobo ezinzima phakathi iingubo ze-fluoropolymer, ngokuqina okugqwesileyo kunye nokumelana neekhemikhali ezibalaseleyo. Iyakwazi ukusebenza ngokuqhubekayo nangokuzinzileyo kwi-149℃. Olu tyaba lunikezelwa kuphela kwifom yomgubo kwaye lunokusetyenziswa ukwenza i-coating kunye nobukhulu obukhulu be-1000 microns, enika ukuqina okuqinileyo kokukhusela. Inguqulelo yayo esekwe kwi-solvent iphinde ixutywe kunye ne-resin yokusebenza okuphezulu ukunyusa ukunamathela kunye nokumelana nokunxiba ngelixa igcina iipropathi ezingundoqo ezifana nokukhuhlana okuphantsi kunye nokungabambeki.
• Ukusetyenziswa okuqhelekileyo: Kufanelekile kwiimeko ezifuna ubulukhuni bokugquma okuphezulu kunye nokunganyangeki, okufana neetanki zokugcina kwimizi-mveliso kunye nezixhobo zokusebenza. Isenokusetyenziswa kumphezulu wamacandelo athile afuna ukugqunywa kombane, ehambelanayo nezahlulo ezahlukeneyo zetsimbi kuquka intsimbi yekhabhoni kunye nealuminiyam.

2. FEP Thermoplastic Fluorocarbon Powder Coating

• Ukusebenza okuPhambili: Iyanyibilika kwaye igeleze ngexesha lokubhaka ukwenza ifilimu engekho-porous, egudileyo engenaziphene zepinhole. Xa isetyenziswe nge-primer efanelekileyo, inokubophelela ngokuqinileyo kwii-substrates zetsimbi. Inokumelana neekhemikhali okugqwesileyo, ukuxhathisa ukufuma, kunye nokungabambeleli, kunye ne-coefficient ephantsi yokukhuhlana. Obona bushushu bokusebenza buphezulu yi-204℃, kwaye i-process threshold isezantsi kakhulu-ingenza ifilimu ngokuntywila kwi-300℃. Ifumaneka kuzo zombini iifom zomgubo kunye nolwelo olusekwe emanzini.
• Izicelo eziqhelekileyo: Ngokuqhelekileyo zisetyenziswa kwiimeko ezifuna ukusebenza okungekho ntonga kunye nokukhuselwa kwe-corrosion eyisiseko, njengamatanki amancinci okugcina kwishishini lemichiza, i-metal mold surfaces, ukukhupha imibhobho yokuvelisa i-semiconductor, kunye neenkqubo zokuqhawula ifilimu ngenjongo yokuchasana nokunamathela.

3. PFA Thermoplastic Fluorocarbon Powder Coating

• Ukusebenza okuPhambili: Kwakhona kuyancibilika kunye namanqanaba ngexesha lokubhaka ukwenza ifilimu engekho-porous, kunye nokusebenza okungaphezulu kwe-FEP. Ubushushu bokusebenza obuqhubekayo bunokufikelela kwi-260℃, kwaye inokuqina okuqinileyo, kunye nobukhulu befilimu obuyi-1000 microns. Idibanisa ukuxhathisa okugqwesileyo kweekhemikhali, ukukhulula iipropathi, kunye nokufana kwengubo. Ngexesha lokucubungula, ingasetyenziswa ngokutshiza ngomgubo oqhelekileyo we-electrostatic okanye izixhobo zokulala ezimanzi, kunye nozinzo oluqinileyo lwe-thermal olufanelekileyo kwiinkqubo zokugubungela ubushushu obuphezulu.
• Usetyenziso oluqhelekileyo: Ukulungelelaniswa kwiimeko ezineemfuno ezingqongqo zokumelana nobushushu obuphezulu kunye nokumelana neekhemikhali, njengemibhobho yokudluliselwa kweekhemikhali ezicocekileyo kwishishini le-semiconductor, ii-reactors zekhemikhali, kunye nezixhobo ezithe ngqo kwilabhoratri. Yenye yezona zinto zikhethwayo zokukhusela umhlwa kwimizi-mveliso kunye nokukhusela izixhobo ezikhethekileyo.

Ukubonisa ngokucacileyo umahluko phakathi kwezi zintathu, ilandelayo yitheyibhile yokuthelekisa iimpawu eziphambili:
