1. Joyina ngokuthe ngqo ngexesha lokuvelisa
1. Yongeza amanzi acocekileyo kwibhakethi enkulu exhotywe nge-blender ephezulu yokucheba.
2. Qala ukuvuselela ngokuqhubekayo ngesantya esiphantsi kwaye ucofe i-hydroxyethyl cellulose kwisisombululo ngokulinganayo.
3. Qhubeka uvuselela de onke amasuntswana afakwe emanzini.
4. Emva koko yongeza i-antifungal agents, izongezo ze-alkaline ezifana ne-pigments, i-dispersing aids, amanzi e-ammonia.
5. Gxuma de yonke i-cellulose ye-hydroxyethyl ichithwe ngokupheleleyo (i-viscosity yesisombululo iyanda kakhulu) ngaphambi kokuba ungeze amanye amacandelo kwifomula, kwaye ugaye de kube yimveliso egqityiweyo.
2. Uxhotyiswe ngotywala bemama ukulinda
Le ndlela kukuqala ukulungiselela utywala oomama kunye noxinzelelo oluphezulu, kwaye ungeze kwipeyinti ye-latex.Inzuzo yale ndlela kukuba inokuguquguquka okukhulu kwaye inokongezwa ngokuthe ngqo kwipeyinti egqityiweyo, kodwa kufuneka igcinwe ngokufanelekileyo.Amanyathelo afana namanyathelo 1-4 kwindlela yoku-1, ngaphandle kokuba ukuvuselela okuphezulu akufuneki ukuchithwa ngokupheleleyo kwisisombululo se-viscous.
3.Ilungiselelwe ukuba isetyenziswe kwisidudu
Kuba izinyibilikisi zendalo zizinyibilikisi ezilambathayo zeselulosi ye-hydroxyethyl, ezi zinyibilikisi zisenokusetyenziswa ukulungisa iimveliso ezifana nesidudu.Ezona zinyibiliki zisetyenziswa kakhulu zilwelo lwendalo olukwimixube yepeyinti efana ne-ethylene glycol, ipropylene glycol kunye nefilmforms (umz. i-ethylene glycol okanye i-diethylene glycol butyl acetate).Amanzi omkhenkce nawo asisinyibilikisi esilambathayo, ngoko ke amanzi omkhenkce asoloko esetyenziswa kunye nolwelo lwendalo ukulungiselela iimveliso ezifana nesidudu.Imveliso efana ne-porridge, i-hydroxyethyl cellulose, inokongezwa ngokuthe ngqo kwipeyinti, kwaye i-hydroxyethyl cellulose ifakwe i-foam kwaye idumbile nge-porridge.Xa ifakwe kwipeyinti, iyancibilika ngokukhawuleza kwaye iyancipha.Emva kokongeza, kusekho imfuneko yokuqhubela phambili de i-hydroxyethyl cellulose ichithwe ngokupheleleyo kwaye ifane.Ngokuqhelekileyo, imveliso efana ne-porridge ixutywe kunye neengxenye ezintandathu ze-organic solvent okanye amanzi e-ice kunye nenxalenye enye ye-hydroxyethyl cellulose.Emva kwemizuzu emi-6 ukuya kwengama-30, i-hydroxyethyl cellulose iya kwenziwa i-hydrolyzed kwaye idumbe ngokucacileyo.Ehlotyeni, ubushushu bamanzi buphezulu kakhulu, kwaye akufanelekanga ukusebenzisa iimveliso ezifana ne-porridge.
