Ukuqhathaniswa Kwezingqimba Zempuphu Ezintathu Ze-Fluorocarbon (ETFE, FEP, PFA): Izakhiwo Nezicelo

Zonke ziyingxenye yezigaba ezibalulekile ze-Teflon-based coatings. Ngokusebenzisa izakhiwo zama-fluoropolymers, adlala indima yokuvikela efana nokumelana nokugqwala, ukusebenza okungeyona induku, nokumelana nezinga lokushisa eliphezulu ezimbonini nakweminye imikhakha. Kodwa-ke, lezi zintathu ziyehluka ngezinga lokushisa lokusebenza, ukusebenza kwe-coating, kanye nezimo zohlelo lokusebenza. Umehluko othize umi kanje:

1. I-ETFE Thermoplastic Fluorocarbon Powder Coating

• Ukusebenza Okubalulekile: Ingolunye lwezinhlobo ezinzima phakathi i-fluoropolymer coatings, ngokuqina okuhle kakhulu kanye nokumelana namakhemikhali okuvelele. Ingasebenza ngokuqhubekayo nangokuzinza ku-149 ℃. Lokhu kunamathela kunikezwa kuphela ngefomu lempushana futhi kungasetshenziswa ukwenza ukujiya okunobukhulu obungama-microns ayi-1000, okunikeza ukuqina okuqinile kokuvikela. Inguqulo yayo esekelwe ku-solvent iphinde ixutshwe nama-resin asebenza kahle ukuze kuthuthukiswe ukunamathela nokumelana nokugqoka kuyilapho igcina izici eziyinhloko njengokungqubuzana okuphansi nokunganamathelani.
• Izinhlelo zokusebenza ezijwayelekile: Zifanele izimo ezidinga ubulukhuni bokumboza okuphezulu nokumelana nokuguga, njengamathangi okugcina izimboni namakesi wempahla. Ingasetshenziswa nangaphezulu kwezinye izingxenye ezidinga ukufakwa kukagesi, ezihambisana nezinsimbi ezihlukahlukene ezihlanganisa i-carbon steel ne-aluminium.

2. I-FEP Thermoplastic Fluorocarbon Powder Coating

• Ukusebenza Okubalulekile: Iyancibilika futhi igeleze ngesikhathi sokubhaka ukuze yakhe ifilimu engenazimbotshana, ebushelelezi ngaphandle kokulimala kwephinifa. Uma isetshenziswa nge-primer efanelekile, ingabopha ngokuqinile kuma-substrates ensimbi. Inokumelana namakhemikhali okuhle kakhulu, ukumelana nomswakama, nokunganamathelani, ene-coefficient ephansi yokungqubuzana. Izinga lokushisa eliphezulu lokusebenza ngu-204℃, futhi umkhawulo wokucubungula uphansi kakhulu-ingakha ifilimu ngokucwilisa cishe ku-300℃. Itholakala kuzo zombili izinhlobo ze-powder nezisekelwe emanzini.
• Izicelo Ezijwayelekile: Ngokuvamile zisetshenziswa ezimeni ezidinga ukusebenza okungagxili kanye nokuvikelwa kokugqwala okuyisisekelo, okufana namathangi amancane okugcina embonini yamakhemikhali, indawo yokubunjwa yensimbi, amapayipi okukhipha umoya ekukhiqizeni ama-semiconductor, nezinqubo zokucwenga ifilimu ngezinjongo zokunqanda ukunamathela.

3. I-PFA Thermoplastic Fluorocarbon Powder Coating

• Ukusebenza Okubalulekile: Kuyancibilika futhi namazinga ngesikhathi sokubhaka ukuze kwakheke ifilimu engenazimbobo, nokusebenza okuphakeme kune-FEP. Izinga lokushisa eliqhubekayo lokusebenza lingafinyelela ku-260 ℃, futhi linokuqina okuqinile, nogqinsi lwefilimu oluwugqinsi lwama-microns angu-1000. Ihlanganisa ukumelana nokugqwala kwamakhemikhali okuhle kakhulu, izakhiwo zokukhulula, kanye nokufana kwe-coating. Ngesikhathi sokucubungula, ingasetshenziswa ngokufafaza okujwayelekile kwe-electrostatic powder noma imishini yokulala emanzi, ngokuzinza okuqinile okushisayo kulungele izinqubo zokugqoka ezisezingeni eliphezulu.
• Izicelo Ezijwayelekile: Zijwayelana nezimo ezinezidingo eziqinile zokumelana nezinga lokushisa eliphezulu nokumelana namakhemikhali, njengamapayipi okudlulisa amakhemikhali ahlanzekile kakhulu embonini ye-semiconductor, ama-reactor amakhemikhali, kanye nezisetshenziswa eziqondene nelabhorethri ethile. Ingenye yezingubo ezithandwayo zokuvikela ukugqwala okukhulu kwezimboni kanye nokuvikela imishini ekhethekile.

Ukukhombisa ngokucacile umehluko phakathi kokuthathu, okulandelayo yithebula lokuqhathanisa lezimpawu ezibalulekile:
