Ukumelana nokubola kweentlobo ezahlukeneyo zokugquma kwe-ppgi ppgl coil nayo yahlukile.Ngokomzekelo, kwimeko yobunzima obufanayo bokugquma, ukuxhathisa ukubola kweishushu-dip yenziwe yagalvanizediicoatings ziphezulu kunezo zeengubo ezishushu zediphu.Ukongeza, uxhathiso lwe-corrosion ngokubanzi luyanda njengoko ubunzima bokugquma bukhula, ngoko ke ukuxhathisa kokutya kwepaneli ezigqunywe ngombala kunokuphuculwa ngokusebenzisa ii-substrates ezinokumelana nokukhula okuphezulu okanye ngokunyusa ubunzima bokugquma.
Ubunzima bokugquma
Ukumelana nomhlwa kwekhoyili yentsimbi epeyintwe ngaphambili (umbala coil steel camera) ihambelana ngokusondeleyo nobukhulu bengubo.Ngokuqhelekileyo, ukuxhathisa kwe-corrosion kuyanda ngokunyuka kobunzima bokugquma.Ubukhulu obufanelekileyo bokugquma kufuneka bumiselwe ngokusekelwe kukonakala kwendalo, ubomi benkonzo kunye nokuqina.
Umahluko wombala wokwaleka
PPGII-PPGL inokuba nokwahlukana kombala ngexesha lemveliso kunye nokusetyenziswa.Ekubeni umahluko wemibala uchatshazelwa zizinto ezahlukeneyo ezifana nebhetshi yemveliso, ubunzulu bombala, ixesha lokusebenzisa, imeko-bume yokusetyenziswa, kunye nenjongo, kudla ngokuthethathethwana ngabo bobabini umthengisi kunye nomthengi xa kuodolwa.
Iglosi yokwambathisa
Iglosi yokwambathisa ikhethwa ikakhulu ngokwesicelo kunye nemikhwa yokusetyenziswa.Ngokomzekelo, ii-coil zensimbi ezifakwe ngemibala yasekhaya zihlala zikhetha i-gloss ephakathi kunye nesezantsi, kunye neepaneli ezifakwe ngombala kwizixhobo zasekhaya zihlala zikhetha i-gloss ephezulu.
Ubulukhuni bokugquma
Ubunzima bokugquma bubuchule bokukwazi ukumelana nemikrwelo, ukungqubana, ukungqubana, ukunyanzeliswa kunye nezinye iziphumo zomatshini.Inxulumene ngokusondeleyo nokumelana nokuqala, ukumelana nokunxiba, ukuchasana nokufakwa kunye nezinye iipropathi zeppgi.ppgliphepha , iindlela zokucubungula, ukugcinwa kunye neemeko zokuthutha, njl.
Ukwaleka ukuguquguquka / ukunamathela
Ukuguquguquka / ukunamathela kwengubo kuhambelana ngokusondeleyo kunye nokunyanzeliswa kwephepha elifakwe umbala, kwaye ukhetho lusekelwe ikakhulu kwindlela yokucubungula kunye neqondo lokuguqulwa.Xa isantya sokuguqulwa sikhawuleza kwaye idigri ye-deformation inkulu, ipleyiti efakwe umbala enexabiso eliphezulu lefuthe lamandla kunye nexabiso elincinci le-T-bend kufuneka likhethwe.
Ukwaleka Ukuqina
Ukuqina kwe-coating kukusebenza kwephepha elifakwe umbala ngexesha lokusetyenziswa, kwaye ngokuqhelekileyo lilinganiswa nobude bobomi benkonzo.Ukomelela kokwaleka kuchatshazelwa ikakhulu zizinto ezifana nohlobo lokutyabeka, ubukhulu bokwambathisa, kunye nokudleka kokusingqongileyo.Ukuqina kokwenyani kweengubo kunokumiselwa ngovavanyo lwe-atmospheric exposure.Ukuqina nako kunokuvavanywa ngovavanyo lokuguga olwenziwayo.Uvavanyo lokumelana nokutshizwa kwetyuwa ngokungathathi hlangothi yenye yezona ndlela zilula neziqhelekileyo zisetyenziswayo zovavanyo lokuguga, kwaye isibane se-UV esikhawulezileyo sovavanyo lokuguga lukwaluvavanyo lokuguga oluqhelekileyo olusetyenziswayo.Ukongeza, ibhodi efakwe umbala ingasetyenziselwa kwiindawo ezikhethekileyo ezifana nemvula ye-asidi kunye nokufuma.Ngeli xesha, uvavanyo lokuguga oluhambelanayo kufuneka lukhethwe ukuba luvavanywe.Kufuneka kuqatshelwe ukuba iimvavanyo zokuguga ezenziweyo zihlala zingakwazi ukulinganisa ngokupheleleyo indawo yokusetyenziswa.
Ezinye iipropati
Kwezinye iimeko, ibhodi egqunywe ngombala kunokufuneka ibe nokuxhathisa okungcono kwe-solvent, i-asidi kunye nokumelana ne-alkali, ukuxhathisa ukungcola kunye nezinye iipropati, kwaye ingqalelo kufuneka ihlawulwe kwiipropati ezikhethekileyo ezinjalo.
