Ubunzima obahlukeneyo buhlala bukhona kwi-zinc-aluminiyamukutyabekainkqubo, kunye nendlela yokufumana unobangela wokwenene obu bunzima iye yaba yinto enzima kwishishini lokwaleka.
Ngaphandle kwemveliso yemveliso ngokwayo, eyona nto ibaluleke kakhulu ekrwada kwi-zinc-aluminium yokwaleka sisisombululo se-zinc-aluminium micro-coating.Ukulawulwa kakubi kwesisombululo se-zinc-aluminium yokugquma kunokukhokelela kwizinto ezininzi ezingafunekiyo, ezinje ngokuqokelelwa kwesisombululo, inkangeleko emnyama ngokubanzi, i-watermark sagging, ukunamathiswa kakubi, kunye nokusilela kokutshiza ityuwa, njl.
Ukuqokelelwa kwesisombululo kuninzi ngenxa ye-viscosity ephezulu kakhulu kunye nobushushu besisombululo sokugquma kunye nokungaphumeleli kwe-centrifugal ukugubha ngokufanelekileyo isisombululo esingaphezulu.
Inkangeleko emnyama iyonke ikakhulu ngenxa yokuba isisombululo sokugquma asishukunyiswa ngokulinganayo kwaye umxholo oqinileyo womaleko ongaphezulu wesisombululo sokwaleka uphantsi, ngoko ke nokuba i-adsorbed kwi-workpiece yokwambathisa iya kulahleka (izithako ezisebenzayo zilahlekile. kwinxalenye yendawo) ngokuhamba kwesisombululo sokwambathisa ngokwaso emva kokungena kumjelo wokumisa.
I-Watermark sagging ibangelwa ikakhulu kukuxuba okungalinganiyo kunye nombala ongahambelaniyo wesisombululo sokugquma.
Ukuncamathela okulambathayo kubangelwa ikakhulu zizinto ezininzi ezingasebenziyo kwisisombululo sokugquma (ezifana nokudutyulwa kwentsimbi, i-oxidized resin, kunye nothuli lwentsimbi).
Kukho izizathu ezininzi zokungaphumeleli kokutshiza ityuwa, kwaye naluphi na utshintsho olufihlakeleyo kwisisombululo se-zinc-aluminium siya kuba nefuthe kuyo.Nangona kunjalo, isitshizi setyuwa yeyona nto ibalulekileyo esiyidingayo ukuze sifezekise injongo.
Ngoko ke, kubalulekile ukuqinisekisa ukuba ukugcinwa kunye nokusetyenziswa kwesisombululo sokugquma kulawulwa.
Ukugcinwa kunye nokusetyenziswa kwamanqaku e-zinc-aluminiyam isisombululo sokugubungela kwinkqubo yokugqoka
1. Umlinganiselo wesalathisi sokuSebenza sesisombululo sokwambathisa
Ukulinganisa i-viscosity rhoqo nge-2h, yenza umlinganiselo wobushushu kunye nokufuma rhoqo nge-2h, kwaye ulinganise umxholo oqinileyo kanye kwishifti nganye
2. Ukuxuba isisombululo sokusebenza kwepeyinti
Umxube omkhulu kufuneka usetyenziselwe ukuxuba ngokupheleleyo isisombululo sokutya okusebenzayo kwitanki yokudipha i-15min ngaphambi kokungena kumgca wokugquma, kunye nesisombululo se-oyile esisekwe kumgca wokugquma kufuneka sitsalwe kumgca emva kweeyure ezili-12 zomsebenzi oqhubekayo kunye nokubuyisela kwakhona. -ixutywe i-10min kwigumbi lokukhupha ngaphambi kokuba i-intanethi isetyenziswe.
Ngokutsho kwesicwangciso sokucwangciswa kwemveliso, isisombululo sokugubungela ukhuseleko lokusingqongileyo lwamanzi kufuneka sitsalwe emva kwigumbi lokuhambisa elitywinwe kwiqondo lobushushu elingaguqukiyo ukuthintela ukuguga kwesisombululo sokwaleka ukuba akukho sicwangciso semveliso sikhoyo ubuncinane iintsuku ezintathu.
3. Ukuhluzwa
Hlunga i-oyile-basedukutyabekaisisombululo kanye ngeentsuku ezi-3 zokusebenza, isisombululo se-oyile-top-coating kanye ngeentsuku ezi-7 zokusebenza, kunye nesisombululo sokugubungela ngamanzi kanye ngeentsuku ezili-10 zokusebenza.Ngexesha lokuhluza, susa intsimbi yentsimbi kunye nomgubo wentsimbi kwisisombululo sokugquma.Ukuphindaphinda kokucoca kufuneka kwandiswe kwimozulu eshushu okanye kwimeko yeengxaki zomgangatho.
4. Uhlaziyo
Ngethuba lokusetyenziswa okuqhelekileyo kwesisombululo sokugubungela kwi-tank yokucoca, isisombululo sokugubungela kunye nesincinci esixutywe kwigumbi lokukhupha sidityaniswe kwaye sihlaziywe.
Ukuhlolwa kwedatha kufuneka kugqitywe kwisisombululo sokugquma esingasetyenziswanga ubuncinane kwiveki enye kwitanki yokudipha ngaphambi kokuba ifakwe kumgca wokugubungela kwakhona, kwaye ayikwazi ukufakwa kumgca ngaphandle kokuba ukuhlolwa kufanelekileyo.Ukuba kukho ukutenxa okuncinci, khupha i-1/4 yesisombululo sokugquma kwitanki yokudipha, yongeza i-1/4 yesisombululo esitsha sokuhlaziya, kwaye ukhuphe inxalenye yesisombululo sokuqala ukuba sifakwe ngendlela ye-1: 1 xa uxuba isisombululo esitsha kwimveliso elandelayo.
5. Ulawulo lokugcina
Ubushushu bokugcina kunye nokufuma (ngokukodwa ehlotyeni) kufuneka kulawulwe kwaye kubhalwe ngokungqongqo ngokuhambelana nemiyalelo, kwaye kuxelwe ngexesha xa umgangatho ugqithisiwe.
Iqondo lokushisa lokugcinwa kwetanki yesisombululo sokugubungela kwigumbi lokukhupha kufuneka lisondele kangangoko kunokwenzeka kwiqondo lokushisa langaphandle ukuze ugweme amaconsi amanzi ngenxa yendawo yombethe ukuchaphazela ukusebenza kwesisombululo.Ubushushu bogcino lwetanki entsha yokwambathisa yi-20±2℃ phambi kokuvulwa.Xa umahluko phakathi kwesisombululo esitsha sokugquma kunye nobushushu bangaphandle bukhulu, itanki yesisombululo kufuneka ivalwe ngaphandle kweeyure ze-4 ngaphambi kokuba idibanise ukuqinisekisa ukuba ukushisa ngaphakathi nangaphandle kwetanki kuyafana.
6. Imiqathango yokusetyenziswa
(1) Naliphi na itanki yomxube wokugquma engena okanye ephuma kwigumbi lokulahla kufuneka ivalwe ngefilim ejikelezayo kwaye igqunywe ngesivalo setanki.
(2) Thabatha amanyathelo okuzikhusela xa kunetha kwaye kufumeme kakhulu.
(3) Ngexesha lokuvalwa kwethutyana okubangelwa ziingxaki zezixhobo ezahlukeneyo, itanki yokudipha mayingavezwa kwindawo engasebenziyo ngaphezulu kweeyure ezi-4.
(4) Ukuqinisekisa ukuzinza kwesisombululo sokugquma, akukho zixhobo ezishushu (ingakumbi ii-workpieces ezingakhange zipholile kwiqondo lokushisa lokushisa) kufuneka zidibanise nesisombululo sokugubungela kuyo yonke imigca.
