Ukusetyenziswa kwe-cellulose ye-hydroxyethyl kwipende ye-latex ngolu hlobo lulandelayo: 1. Yongeza ngokuthe ngqo xa ugaya i-pigment: le ndlela ilula, kwaye ixesha elisetyenzisiweyo lifutshane. Amanyathelo acacisiweyo alandelayo: (1) yongeza amanzi ahlambulukileyo afanelekileyo (ngokuqhelekileyo, i-ethylene glycol, i-agent yokumanzisa kunye ne-agent-forming agent yongezwa ngeli xesha) (2) qalisa ukuvuselela ngesantya esiphantsi ngokuqhubekayo kwaye ngokukhawuleza ungeze i-cellulose ye-hydroxyethyl (3) qhubeka uvuselela de kube zonke iinqununu zimanzi (4) zongeza inhibitor ye-mildew; Umlawuli we-PH, njl. (5) ugxobhoze de yonke i-cellulose ye-hydroxyethyl ichithwe ngokupheleleyo (i-solution viscosity ukwanda) ngaphambi kokuba ungeze amanye amacandelo efomyula, ukugaya kuze kube yipeyinti.
2.Equipped kunye nonina utywala elinde ukusetyenziswa: le ndlela ixhotyiswe kuqala ngoxinaniso eliphezulu lotywala unina, kwaye emva koko yongezwa ipeyinti latex, le ndlela inenzuzo bhetyebhetye enkulu, inokongezwa ngokuthe ngqo kwimveliso yepeyinti, kodwa kufuneka igcinwe ngokufanelekileyo. Amanyathelo kunye neendlela zifana namanyathelo (1) - (4) kwindlela ye-1, ngaphandle kokuba i-agitator ye-shear ephezulu ayifuni, kwaye kuphela i-agitator enamandla okwaneleyo ukugcina i-hydroxyethyl fibers ihlakazwe ngokufanayo kwisisombululo esifunekayo. Qhubeka uvuselela de inyibilike ngokupheleleyo kwisisombululo se-viscous. Kufuneka uqaphele ukuba: inhibitor ye-mildew kufuneka yongezwe kutywala bemama ngokukhawuleza. 3. I-Congee kunye ne-phenology: njengoko i-solvents ye-organic ye-hydroxyethyl cellulose i-solvent embi, ngoko ke ezi zinyibilikisi ze-organic zingasetyenziselwa ukulungiselela i-congee. Ngokuqhelekileyo zisetyenziselwa i-solvents eziphilayo ezifana ne-ethylene glycol, i-propylene glycol, kunye ne-film-forming agents (ezifana ne-hexanediol okanye i-diethylene glycol butyl acetate) , amanzi e-ice nawo ayisinyibiliki esibi, ngoko ke isetyenziswa rhoqo kunye ne-organic liquids ukulungiselela i-porridge. I-porridge efana ne-hydroxyethyl cellulose inokongezwa ngokuthe ngqo kwipeyinti. I-Hydroxyethyl cellulose ifakwe ngokupheleleyo kwisidudu. Xa i-lacquer yongezwa, iyachithwa ngokukhawuleza kwaye iyancipha. Emva kokongeza, kufuneka iqhutywe ngokuqhubekayo de i-hydroxyethyl cellulose ichithwe ngokupheleleyo kwaye ifane. Ngokuqhelekileyo isidudu sineenxalenye ezintandathu ze-organic solvent okanye amanzi e-ice kunye nenxalenye yomxube we-hydroxyethyl cellulose, malunga nemizuzu emi-5-30 kamva, i-hydroxyethyl cellulose iya kuhlanjululwa kunye nokudumba. Ihlobo xa ukufuma kwamanzi ngokubanzi kuphezulu kakhulu, akufanelekile ukuxhotyiswa nge-porridge.
3.Zine. Qaphela xa ulungiselela utywala oomama be-hydroxyethyl cellulose ekubeni i-hydroxyethyl cellulose i-particle ephathwayo engumgubo, kulula ukuyisebenzisa kunye nokunyibilika emanzini ngokuthobela oku kulandelayo. I-1 ngaphambi nangemva kokongeza i-hydroxyethyl cellulose, umxube kufuneka uqhutywe ngokuqhubekayo de isisombululo sibonakale ngokucacileyo kwaye sicace. I-2 kufuneka ihlulwe kwi-drum yokuxuba, ingabi nenani elikhulu leengqungquthela okanye iibhola ze-hydroxyethyl cellulose zongezwe ngokuthe ngqo kwi-drum yokuxuba. I-3 i-solubility ye-hydroxyethyl cellulose inxulumene nobushushu bamanzi kunye nexabiso le-pH emanzini, ekufuneka ihlawulwe ingqalelo ekhethekileyo. 4 ungafaki ezinye izinto ezisisiseko kumxube phambi kokuba umgubo we-hydroxyethyl cellulose uzaliswe ngamanzi. Ukunyusa i-pH emva kokumanzisa kunceda ukunyibilika. 5 kangangoko kunokwenzeka, kwangethuba ukongeza i-agent anti-mildew. 6 xa usebenzisa i-viscosity ephezulu ye-hydroxyethyl cellulose, i-concentration yotywala yomama ayinakuba ngaphezulu kwe-2.5-3% (i-gravimeter) , ngaphandle koko utywala oomama kunzima ukusebenza. Izinto ezichaphazela i-viscosity yepeyinti ye-latex:
1 Okukhona umxholo wamaqamza omoya kwipeyinti, kokukhona i-viscosity iphezulu. 2 inani le-activator yomhlaba kunye namanzi asetyenziswe kwifomula yepeyinti ifanelekile. I-3 kwi-synthesis ye-latex, inani le-catalysts eseleyo kunye nezinye i-oxides. 4 ubungakanani bezinye i-thickeners zendalo kwifomula yepeyinti kunye nomlinganiselo kunye ne-hydroxyethyl cellulose. 5 kwinkqubo yepeyinti, ukongeza i-thickener ulandelelwano lwamanyathelo lufanelekile. 6 ngenxa yokuphazamiseka okugqithisileyo ukuze xa kuthe saa ukufuma kushushu. I-7 microbial corrosion ye-Thickener.
