Isebenza njani i-E-coating
Inkqubo yokugqoka i-electrophoretic, eyaziwa ngokuba yi-E-coat, iquka ukucwiliswa kweengxenye kwisisombululo esisekelwe emanzini esine-emulsion yepende. Emva kokuba iziqwenga zintywiliselwe, kusetyenziswe umsinga wombane, oku kuvelisa ukusabela kweekhemikhali okubangela ukuba ipeyinti ibambelele kumphezulu. Umaleko ofanayo wenziwa kwisiqwenga kuba iindawo eziza kupeyintwa zihlala zodwa, ezibathintela ekufumaneni ubukhulu obukhulu bepeyinti.
Isetyenziswe ngokubanzi kwicandelo lobunjineli ngokubanzi ukusebenzisa i-primer okanye i-coatings yokukhusela, i-electrophoretic coating, i-electropainting, i-electrodeposition, i-electrophoretic deposition (EPD), okanye i-e-coating, zonke zizihloko zenkqubo esebenza kwi-epoxy encinci, ehlala ixesha elide kunye ne-corrosion-resistant. resin ukutyabeka kumacandelo metal.
Umboniso weMveliso
Izinto eziluncedo kwiNkqubo yoMbane
Kukho iinzuzo ezininzi zokufakelwa kwe-electrocoating, kubandakanya ukusebenza kweendleko, imveliso yomgca kunye neenzuzo zokusingqongileyo. Ukuphumelela kweendleko kwi-electrocoat kukusebenza okuphezulu kokudluliselwa, ulawulo oluchanekileyo lokwakhiwa kwefilimu, kunye neemfuno eziphantsi zabasebenzi. Ukonyuka kwemveliso yomgca kwi-electrocoat kungenxa yezantya zomgca okhawulezayo, ukurhaxwa okuxineneyo kwamalungu, ukulayishwa komgca ongekho yunifomu, kunye nokunciphisa ukudinwa kwabantu okanye impazamo.
Izibonelelo zokusingqongileyo azikho okanye zisezantsi-okanye i-low-VOC kunye neemveliso ze-HAPs, iimveliso ezinzima ezingenazintsimbi, ukunciphisa ukuvezwa kwabasebenzi kwizinto ezinobungozi, iingozi zomlilo ezincitshisiweyo, kunye nokukhutshwa kwenkunkuma encinci.
Amanyathelo aphambili
Coca umphezulu
I-oyile, inkunkuma kunye nezinye iintsalela ezinokuthintela ukunamathela kwe-e-coat. Ngoko ke, umphezulu kufuneka ucocwe ngokufanelekileyo ngaphambi kokuba uqhubele phambili. Uhlobo lwesisombululo sokucoca olusetyenzisiweyo luya kuhluka ngokusekelwe kuhlobo lwetsimbi. Ngentsimbi kunye nentsimbi, isisombululo se-phosphate ye-inorganic ngokuqhelekileyo sikhethwa. Kwisilivere negolide, abacoci bealkaline baxhaphake kakhulu.
Isicoci se-ultrasonic sisixhobo esifanelekileyo salo msebenzi. Le itanki isebenzisa ii-vibrations zoomatshini ukwenza amaza omsindo emanzini okanye kwisisombululo sokucoca. Xa izinto zetsimbi zifakwe kwisisombululo, iibhubhu ezenziwe ngamaza omsindo ziya kuhlambulula nezo ndawo ezinzima ukufikelela kuzo.
Pula
Emva kokuba into ikhululekile ngokupheleleyo kuyo yonke into engcolileyo kunye nemikrwelo, kufuneka ihlanjululwe ngamanzi adibeneyo kunye ne-neutralizer. Oku kuya kunceda ukususa nayiphi na intsalela ebangelwa yimichiza esetyenziswe kwinkqubo yokucoca. Eli nyathelo kufuneka liphindwe amaxesha ambalwa ukuqinisekisa ukuba into leyo ikhululekile kuyo nayiphi na into engcolileyo. Ngaloo ndlela, uya kuba nethuba elingcono lokubambelela ngempumelelo ngexesha lenkqubo ye-e-coating.
Ukumanzisa idiphu
Abanye abavelisi be-E-coat bacebisa iarhente yokumanzisa idiphu etankini kwangoko phambi kwetanki ye-E-coat. Oku kuqhelekile ukuthintela amaqamza ekubeni abambelele kumalungu njengoko esiya kwitanki ye-e-coat. Naliphi na iqamza elincanyathiselwe kumphezulu wenxalenye liya kuthintela ukubekwa kwe-E-coat kwaye liya kubangela isiphene sepeyinti kwindawo egqityiweyo.
Isisombululo se-E-coating
Xa uqinisekile ngokupheleleyo ukuba loo nto ihlanjululwe ngokucokisekileyo, lixesha lokuyintywilisela kwisisombululo se-e-coating. Iikhemikhali ezisetyenzisiweyo kwisisombululo ziya kuxhomekeka kwizinto ezimbalwa, ezifana nohlobo lwentsimbi eyenziwa ngayo loo nto.
Qinisekisa ukuba yonke into ifakwe emanzini. Oku kuya kuqinisekisa ukuba kukho i-intshi nganye yezinto, kubandakanywa naloo maqhekeza ekunzima ukufikelela kuwo. Imisinga yombane ehamba ngesisombululo iya kubangela ukusabela kweekhemikhali ezidibanisa i-coating kwi-metal surface.
Ukunyanga ukutyabeka
Emva kokuba into isusiwe kwisisombululo se-e-coating, sibhaka kwi-oven. Oku kubangela ukuqina kwengubo ukuqinisekisa ukuqina, kwaye kudala ukugqitywa kwe-glossy. Iqondo lokushisa apho into kufuneka iphiliswe iya kuxhomekeka kwi-chemistry yesisombululo se-e-coating esisetyenzisiweyo.
