Ukugquma idiphu yomgubo kunika iingenelo ezininzi
Inkqubo yokwaleka komgubo wediphu
Umda dip ukutyabeka yindlela yokwaleka apho i-substrate intywiliselwa kwi-powder yokugqoka impahla ukuze kufezekiswe ukugquma. Le nkqubo ibandakanya eziliqela Steps ukuqinisekisa ukusetyenziswa okufanayo kunye nokubambelela ngokufanelekileyo kwengubo.
Inyathelo lokuqala kwi-powder dip coating kukulungiselela i-substrate. I-substrate inokufuna ukucocwa, ikhutshwe, kwaye ihlanjululwe ukuze kuphuculwe ukunamathela komgubo. Nakuphi na ukungcola okanye i-debris phezu komhlaba kunokuchaphazela ukunamathela kunye nomgangatho we-coating.
Emva kokuba i-substrate ilungisiwe, ishushu kwiqondo lokushisa elithile. Ukufudumeza i-substrate kunceda ekuphuculeni ukubambelela komgubo kunye nokukhuthaza ukufana kwengubo engcono. Ubushushu obufunekayo depeIgcina kuhlobo lomgubo wokugquma kunye ne-substrate eqatywe.
Emva koko, i-substrate ifakwe kwisitya esigcwele i-powder coating material. Njengoko i-substrate ihoxiswa kwisitya sokugquma umgubo, umgubo unamathela kumphezulu. Inkqubo yokudibanisa ingaba repeifakwe ixesha elinye okanye ngaphezulu ukwakha ubungqingqwa obunqwenelekayo bokugquma.
Emva kokuntywila, umgubo ogqithisiweyo uyasuswa kwi-substrate. Oku kunokwenziwa ngokusebenzisa izivuthelo zomoya, ukungcangcazela, okanye ezinye iindlela zokususa umgubo okhululekileyo ongazange ubambelele kwi-substrate. Ukususa i-powder engaphezulu kunceda ukufezekisa i-coating egudileyo kunye nefanayo.
I-substrate egqunyiweyo ke ingena kwinqanaba lokunyanga. Ukunyanga ngokuqhelekileyo kwenziwa ngokufudumeza i-substrate kwi-oven okanye ngokusebenzisa ezinye iindlela zokufudumeza. Ubushushu bubangela ukuba umgubo unyibilike, uqukuqele, nto leyo ebangela ukuba ibe yimaleko eqinileyo nehlala ixesha elide. Ixesha lokunyanga nobushushu depekunye nokwakhiwa komgubo owenziweyo kunye nobukhulu bengubo.
eziluncedo
Ukugquma idiphu yomgubo inika iingenelo ezininzi kunezinye iindlela zokugquma. Enye yeenzuzo eziphambili kukukwazi ukufezekisa ubukhulu obufanayo bokugquma kuyo yonke i-substrate. Oku kubaluleke kakhulu kwizicelo apho iimpawu zokugquma ezihambelanayo zibalulekile, ezifana nokugquma umbane okanye ukukhuselwa komhlwa. Ukongeza, iingubo zomgubo zinika ukuqina okulungileyo, ukuxhathisa ukukrwela, ukubola, kunye nokuvezwa kweekhemikhali.
Enye inzuzo yokugquma umgubo kukusebenza kwayo. Inkqubo yokwaleka iyakwazi ukuzenzekelayo, ivumela ukuveliswa kwevolumu ephezulu. Izinto zokugquma umgubo zinokuphinda zisetyenziswe kwaye zisetyenziswe kwakhona, ukunciphisa inkunkuma kunye neendleko. Iingubo zomgubo zikwanazo izinto ezikhutshwayo eziphantsi ze-volatile organic compound (VOC), nto leyo ezenza zikhuseleke ngakumbi kokusingqongileyo xa kuthelekiswa nezinye izinto zokuthambisa ezisekwe kwi-solvent.
Ukugquma idiphu yomgubo ifumana izicelo kumashishini ahlukeneyo. Iqhele ukusetyenziswa kwimizi-mveliso yeemoto, i-electronics, kunye nezixhobo zendlu yokwambathisa izinto ezincinci, ezinje ngezikrufu, iinati, kunye nezibiyeli. I-coating inika ukhuseleko kwi-corrosion, iphucula ukugquma kombane, kwaye ikhulise ukubonakala kwamacandelo. Ukugquma idiphu yomgubo kukwasetyenziswa xa kuveliswa izixhobo zonyango, apho kufuneka icoca ecocekileyo neyinyumba.
Isishwankathelo, i-powder dip coatings yindlela yokwaleka enikezela ngobunzima obufanayo bokugquma, ukuqina, kunye nokusebenza kakuhle. Ngokuntywilisela i-substrate kwi-powder yokugqoka izinto kunye nokunyanga okulandelayo, ukugquma okunzima kunye nokukhusela kufezekiswa. Inkqubo isetyenziswa ngokubanzi kumashishini apho ukugquma iindawo ezincinci okanye amacandelo ayimfuneko, ukubonelela ukusebenza okuphuculweyo kunye nesibheno sobuhle. Iimfuno ezithile kunye neendawo zokusetyenziswa zinokwahluka, kodwa i-powder dip coating iyaqhubeka ibe lukhetho oludumileyo kwizicelo ezininzi zokugquma.
