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 aneenkcukacha ngolu hlobo lulandelayo: (1) yongeza amanzi acocekileyo afanelekileyo (ngokuqhelekileyo, i-ethylene glycol, i-agent yokumanzisa kunye ne-agent-forming agent yongezwa ngeli xesha) (2) qala ukuvuselela ngesantya esiphantsi ngokuqhubekayo kwaye ngokukhawuleza udibanise i-hydroxyethyl cellulose (3) qhubeka ushukumisa de onke amasuntswana amanzi (4) yongeza isithinteli sokungunda;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.Kuxhotyiswe ngotywala komama elinde ukusetyenziswa: le ndlela ixhotyiswe kuqala ngoxinaniso oluphezulu lotywala lukamama, kwaye emva koko ifakwe kwipeyinti ye-latex, le ndlela inenzuzo yokuguquguquka okukhulu, inokuthi ifakwe ngokuthe ngqo kwiimveliso zepeyinti, kodwa kufuneka ibe igcinwe kakuhle.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, ichithwa ngokukhawuleza kwaye iyancipha.Emva kokongeza, kufuneka iqhutywe ngokuqhubekayo de i-hydroxyethyl cellulose ichithwe ngokupheleleyo kwaye ifane.Ngokuqhelekileyo ipapa inamalungu amathandathu e-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 ngesidudu.
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 ihambelana 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 ukwenzela ukuba xa usasazwa ukufuma okugqithisileyo.I-7 microbial corrosion ye-Thickener.
