Ukugqoka
Upende Ongangeni Manzi
Upende Ongangeni Manzi
Ukugqoka okusekelwe emanzini kuwuketshezi lwe-viscous olune-resin, noma uwoyela, noma i-emulsion njenge-ejenti eyinhloko, kanye ne-organic solvent noma amanzi. Izingubo ezisekelwe emanzini ezinokusebenza okuhle kakhulu nazo zinokusebenza okuhle kakhulu kokusebenza, amandla amahle okufihla, ukunamathela okuqinile, ukugcinwa kwamanzi okuhle nezinye izici; I-Cellulose iyimpahla eluhlaza efaneleke kakhulu ukunikeza lezi zakhiwo.
Impahla yokugcina amanzi ye-goldstone cellulose ihlinzeka ngokusebenza okuhle kakhulu kokufakwa kwe-latex, ikakhulukazi embozweni ephezulu ye-PVC. Lapho enamathela uginindela obukhulu, ngeke ukukhiqiza flocculation. Umphumela wawo wokuqina ophezulu unganciphisa umthamo, uthuthukise umnotho wokubunjwa, futhi uthuthukise ukumiswa kwesistimu yokumboza. Izakhiwo ezinhle kakhulu ze-rheological ku-coating, zingagcina isimo esihle kakhulu sokuqina kwe-coating ekuphumuleni; Esimeni sokuthulula, ngokumanzisa okuhle kakhulu, futhi ngeke kuphafuze; Esikhathini sokuxubha nokukhuluma, ukusabalalisa kalula ku-substrate, ukwakhiwa okulula; Ekugcineni, ngemva kokuqedwa koqweqwe, i-viscosity yesistimu ibuyiselwa ngokushesha, futhi ukugqoka kuzokhiqiza ngokushesha ubulili obulengayo. Ngemuva kokwelashwa okufanelekile kwendawo yephazili ye-goldstone cellulose, kungavimbela ngempumelelo ukuqedwa kwe-agglomerate, ehlakazekile ngokugcwele, isikhathi esanele sokuhlakazeka kanye nezinga lokukhuphuka kwe-viscosity lingenza inqubo yokukhiqiza ibe lula; I-cellulose ye-GOLDstone eguquliwe nayo inokusebenza okuhle kokulwa nesikhutha, inikeza isikhathi esanele sokugcina i-coating, futhi ivimbela ngokuphumelelayo ukuhlaliswa kwe-pigments kanye nezigcwalisi.
