Ipeyinti engenamanzi
I-coating esekelwe emanzini i-viscous liquid ne-resin, okanye ioli, okanye i-emulsion njengeyona arhente iphambili, kunye ne-solvent okanye amanzi. Iingubo ezisekelwe emanzini ezinomsebenzi ogqwesileyo nazo zisebenza ngokugqwesileyo, amandla amahle okufihla, ukunamathela okuqinileyo, ukugcinwa kwamanzi okulungileyo kunye nezinye iimpawu; I-Cellulose yeyona nto ifanelekileyo ekrwada ukubonelela ngezi mpawu.
Ipropathi yokugcinwa kwamanzi ye-goldstone cellulose ibonelela ngokugqwesileyo kokutyabeka kwe-latex yokwambathisa, ngakumbi kwi-PVC ephezulu yokwaleka. Xa ukutyabeka kukutyebile, akuyi kuvelisa i-flocculation. Umphumo wayo ophezulu wokuqina unokunciphisa umthamo, uphucule uqoqosho lokuqulunqwa, kwaye uphucule ukumiswa kwenkqubo yokugqoka. Iipropathi ezigqwesileyo ze-rheological kwi-coating, zinokugcina eyona meko igqwesileyo yokwaleka ekuphumleni; Kwimeko yokugalela, kunye ne-fluidity ebalaseleyo, kwaye ayiyi kutshiza; Kwi-brush and spoke coating, kulula ukusabalalisa kwi-substrate, ukwakhiwa okufanelekileyo; Ekugqibeleni, emva kokuba i-coating igqityiwe, i-viscosity yenkqubo ibuyiselwa ngokukhawuleza, kwaye i-coating iya kuvelisa ngokukhawuleza isondo esijingayo. Emva konyango olufanelekileyo lomphezulu wephazili ye-cellulose yegolide, inokuthintela ngokufanelekileyo ukuchithwa kwe-agglomerate, ichithwa ngokupheleleyo, ixesha elaneleyo lokuchithwa kunye nesantya sokunyuka kwe-viscosity kungenza lula inkqubo yemveliso; I-cellulose ye-GOLDstone eguqulelweyo nayo inokusebenza kakuhle kwe-anti-mildew, inika ixesha elaneleyo lokugcina i-coating, kwaye ikhusela ngokufanelekileyo ukuhlaliswa kwee-pigments kunye nezizaliso.
