2. Ubukhulu Bokumboza
3. Ubuqotho Bokumboza
1. Ikhwalithi Yokushisela
Ubuqotho bezembozo zokulungisa uketshezi buxhomeke kakhulu esimweni sejometri somthungo we-weld. Uma umthungo we-weld unamachashaza, ukuphuma okukhulu, noma indawo erhabaxa, izembozo zoketshezi azikwazi ukuwumboza ngokuphelele. Ngaphezu kwalokho, ubukhulu bomthungo we-weld buthinta umphumela wokumboza; ngokuvamile, ubukhulu bomthungo we-weld kufanele bube ngaphansi kwezikhathi eziyi-1.5 ubukhulu bepuleti. Ngensimbi yesibili egoqwe ngokubandayo noma insimbi eqinile kakhulu, ubukhulu bomthungo we-weld buphindwe izikhathi eziyi-1.5 kuya kweziyi-1.8 ubukhulu bepuleti.
Izithungo zokushisela ezenziwe ngaphandle kokuvikelwa kwe-nitrogen zingase zibe nokunamathela okungekuhle kwesembozo sokulungisa ngenxa yezingqimba ze-oxide eziningi, okuholela ekuqhekekeni kwesembozo ngesikhathi sezinqubo ezilandelayo njengokuphambanisa, ukugoba, kanye nokusika, okuthinta ubuqotho besembozo sokulungisa.
Izembozo zempuphu, ngenxa yobukhulu bazo obanele, zingabhekana kahle nezinkinga zokuchayeka kwensimbi ezibangelwa amaphutha okushisela, zinikeze isivikelo esihle kakhulu somthungo wokushisela.
2. Amabhamuza
Ukwakheka kwe-solvent okungenangqondo ezimbozweni zokulungisa uketshezi kungathinta ubuqotho be-coating. Uma i-liquid coating iqukethe i-solvents eningi ephansi yokubila, noma uma izinga lokushisa likhuphuka ngokushesha kakhulu ngesikhathi sokubhaka, noma uma izinga lokushisa le-weld seam liphezulu kakhulu, inani elikhulu le-solvent liyaphela ngesikhathi sokubhaka, lishiye izintambo zama-bubbles noma ama-micropores embozweni, okunciphisa ukumbozwa kanye nomphumela wokuvikela kumthungo we-weld.
4. Ukubhaka Nokuphola
1. Inqubo Yokulungisa Izembozo Zokulungisa
Ukubhaka nokulungisa izembozo eziwuketshezi kungahlukaniswa cishe ngezigaba ezilandelayo: isembozo kuqala silinganise futhi simanzise umthungo wokushisela kanye nezindawo ezingenalutho (cishe imizuzwana eyi-1-2), kulandelwe ukuhwamuka kwe-solvent ukuze kwakheke ijeli (kufanele kuqedwe phakathi kwemizuzwana emi-3-5; ngaphandle kwalokho, isembozo sizogeleza sisuke kumthungo wokushisela), bese ekugcineni senziwa i-polymerization. Isembozo kumele sithole ukushisa okwanele okuphelele, okuthinta kakhulu ukujiya kanye nokusebenza kwesembozo sokulungisa. Njengoba kushiwo ngaphambili, ukunyuka kwezinga lokushisa okusheshayo ngesikhathi sokubhaka kungakhiqiza kalula amabhamuza, kanti ukunyuka kwezinga lokushisa okuhamba kancane kungaholela ekuqineni okunganele ngenxa yokugcinwa kwezinga lokushisa elifushane.
Izembozo ezahlukene zinezikhathi ezihlukene zokufika ngesikhathi sokubhaka; izembozo ze-epoxy phenolic zidinga izikhathi ezinde kunezembozo ze-organosol, okusho ukuthi zidinga ukushisa okwengeziwe ukuze zibhake.
Kwezingubo zokugcoba ezimpushana, izingubo zokugcoba ezisebenzisa i-thermoplastic zimane zincibilike ukuze zakhe ifilimu ngesikhathi sokubhaka ngaphandle kokwenziwa i-polymerization, kuyilapho izingubo zokugcoba ezisebenzisa i-thermosetting zifakwa i-polymerization eyengeziwe ngemva kokwenziwa i-polymerization ngaphambi kokwenziwa i-polymerization futhi zincibilike ukuze zihlanganiswe zibe ama-compounds anama-molecule amaningi. Ngakho-ke, ukushisa kokubhaka kuhlobene kakhulu nokusebenza kwengubo yokulungisa.
2. Umthelela Wezinga Lokuphulukisa Ekusebenzeni Kokumboza
Ukufakwa kokulungisa kungabonisa izici zazo kuphela uma kubhakwe ngokuphelele futhi kuqediwe. Ukubhaka okunganele kuholela ezimbotsheni eziningi ezincane kanye nokungacutshungulwa kahle; isibonelo, ukufakwa kompuphu we-thermoplastic okungabhakiwe ngokwanele kungashwabana ngesikhathi sokuphamba. Ukubhaka ngokweqile kuthinta ukunamathela; isibonelo, ukufakwa kompuphu we-epoxy phenolic okubhakiwe ngokweqile kuba buthakathaka futhi kuthambekele ekuqhekekeni ngesikhathi sokuphamba, ukugoba, kanye nokuphola. Ngaphezu kwalokho, ukupholisa okwanele ngemva kokubhaka kubalulekile ekusebenzeni kokufakwa kokulungisa. Isibonelo, uma ukufakwa kompuphu we-thermoplastic kungapholiswa ngokushesha ekamelweni lokushisa ngemva kokubhaka, ukufakwa kompuphu kungaqhekeka ngesikhathi sokuphamba. Ukwengeza idivayisi yokupholisa ngemva kwehhavini kungavimbela izinkinga zokuqhekeka ekufambeni kokulungisa ngesikhathi sokuphamba.
Ngamafuphi, ukuqinisekisa ikhwalithi yengubo yokulungisa—okungukuthi, ukubhoboka okuphansi kanye nokucutshungulwa okuhle—kubalulekile ukulawula ukujiya kanye nezinga lokuphola kwengubo.
