I-Fluidized bed powder i-coat yi-powder yokugqoka esetyenziswa kunye nenkqubo yebhedi eguquguqukayo apho amasuntswana omgubo ocoliweyo axhonywe emoyeni, kunye nenxalenye eshushu ngaphambili ifakwe kwitanki yomgubo. Iincinci ezinyibilikisiweyo zidibanisa into, zibonelela ngokuhambelana, kunye nokugqiba kwiindawo zetsimbi. Le ndlela ifaneleke kakhulu njengengubo esebenzayo yokubonelela nge-abrasion, i-corrosion, kunye nokumelana nemichiza. Ubungqingqwa obuqhelekileyo bale ndlela yi-200-2000μm ubukhulu, kodwa ubunzima obunzima bunokufezekiswa.

Inxalenye engumgubo eqatywe ngebhedi egudisiweyo idlula kule st ilandelayoeps.

1. Ngaphambi kokufudumeza

Inxalenye yentsimbi kufuneka ifudunyezwe kwi-oven ukuya kwi-220-400 ℃. Eli qondo lobushushu liphezulu kunendawo yokunyibilika yebhedi engumgubo, kwaye yenza ukuba umgubo ucime okanye upholise indawo ngoko nangoko.

2. Ukudipha

Isivutheli-moya esiphantsi kwetanki yomgubo sivuthela amasuntswana omgubo awenze afane nolwelo. Sidibanisa inxalenye eshushu kwibhedi edibeneyo yomgubo we-powder kwaye siyijikeleze ukuze iqhube ngokuqhubekayo. Ubungqingqwa bokugqibela bomsebenzi depeigcina ubushushu bamalungu phambi kokuba ifakwe etankini kwaye ihlale ixesha elingakanani kumandlalo olwelo lwentonga yomgubo.

4.Post-ubushushu ukunyanga

Inqanaba lokugqibela lokugquma kwebhedi engumgubo yinkqubo yokugqibela yokudibanisa. Emva kokuba umgubo uthontsiza kwimveliso, uya e-oveni kwiqondo eliphantsi lobushushu ukuze unyange. I-post-heat kufuneka ibe kwiqondo lokushisa elingaphantsi kwe-oven preheated. Injongo yale nyathelo kukuqinisekisa ukuba yonke i powder ibambelele kwinxalenye ngexesha lokuntywila kwaye inyibilika ibe yingubo egudileyo, efanayo.

5.Ukupholisa

Ngoku susa i-workpiece egqunyiweyo kwi-oven kwaye uyipholise ngefeni yomoya okanye umoya wendalo.

I-Fluidized bed powder coating ibandakanya ukuntywiliselwa i-workpiece eshushu kwitanki yomgubo, evumela ukuba umgubo unyibilike kwindawo kwaye wakhe ifilimu, kwaye emva koko unike ixesha elaneleyo kunye nobushushu ukuze le filimu ihambe ibe yingubo eqhubekayo. I-workpiece kufuneka igxininiswe kumandlalo omanzi ngokukhawuleza emva kokuyisusa kwi-oven yokufudumeza ukugcina ukulahleka kobushushu ubuncinci. Umjikelo wexesha kufuneka usekwe ukugcina eli xesha lokuphumla lingaguquki. Ngelixa i-powder, i-workpiece kufuneka igcinwe kwi-motion ukugcina umgubo uhamba phezu kwendawo eshushu. Isiphakamiso secandelo elithile depends kuqwalaselo lwayo.

Ukushukuma okungafanelekanga okanye okungonelanga kusenokuba ngunobangela weengxaki ezininzi: imingxunya, ngakumbi kumphantsi weendawo ezithe tyaba ezithe tyaba kunye nakwiindawo ezidityanisiweyo zocingo: imbonakalo “yexolo eliorenji” kunye nokungagqumeki ngokwaneleyo kweekona okanye iintanda. Ukushukuma okungafanelekanga nako kunokukhokelela kubunzima bokwaleka obungafaniyo, njengokwaleka okumbhoxo kwiintambo ezingqukuva. Ixesha eliqhelekileyo lokucwiliswa kwi-powder fluidized yimizuzu emithathu ukuya kwe-20.

Umgubo ogqithisileyo kufuneka ususwe ngokukhawuleza emva kokugquma ukukhusela ukwakheka okugqithisileyo. Oku kunokwenziwa ngokuqhushumba komoya osuka kwijethi yomoya elawulwayo, ukucofa okanye ukungcangcazela indawo leyo, okanye ukuyithambeka ukulahla okungaphezulu. Ukuba i-powder engaphezulu ayingcoliswanga ngolunye umgubo okanye ukungcola, ingaphinda isetyenziswe. Ukuba inxalenye inobushushu obaneleyo obushiyekileyo, i-coating ingaphuma ukuya kumanqanaba amkelekileyo ngaphandle kokufudumeza kweposi. Kwiindawo ezibhityileyo, okanye iindawo ezibuthathaka kubushushu, kungafuneka ubushushu besithuba.
