1. Yongeza ngokuthe ngqo xa ugaya i-pigment: Le ndlela yeyona ndlela ilula kwaye ithatha ixesha elincinci. Amanyathelo aneenkcukacha ngolu hlobo lulandelayo:
(1) Yongeza amanzi ahlambulukileyo afanelekileyo kwi-vat ye-agitator ephezulu (ngokubanzi, i-ethylene glycol, i-agent emanzi kunye ne-agent-forming agent zonke zongezwa ngeli xesha)
(2) Qala ukuvuselela ngokuqhubekayo ngesantya esiphantsi kwaye ngokukhawuleza ungeze i-hydroxyethyl cellulose
(3) Qhubeka ushukumisa de onke amasuntswana agalelwe
(4) Yongeza i-agent ye-antifungal, i-PH adjuster, njl.
(5) Gxuma de yonke i-cellulose ye-hydroxyethyl ichithwe ngokupheleleyo (i-viscosity yesisombululo inyuka kakhulu) ngaphambi kokuba ungeze amanye amacandelo kwifomula, kwaye ugaye de ibe yipeyinti.
2. Lungisa utywala bukamama ukuze busetyenziswe: Le ndlela kukulungisa utywala bukamama ngogxininiso oluphezulu kuqala, kwaye bongeze kwipeyinti yelatex. Inzuzo yale ndlela kukuba inokuguquguquka okukhulu kwaye inokongezwa ngokuthe ngqo kwipeyinti egqityiweyo, kodwa kufuneka igcinwe ngokufanelekileyo. Amanyathelo kunye neendlela zifana namanyathelo (1) - (4) kwiNdlela yoku-1, umahluko kukuba akukho mfuneko ye-agitator ephezulu yokucheba, kwaye kuphela ezinye ii-agitators ezinamandla ngokwaneleyo ukugcina iifayili ze-hydroxyethyl zihlakazwe ngokufanayo. isisombululo zisetyenziswa. Ngaba. Qhubeka nokuvuselela rhoqo de unyibilike ngokupheleleyo kwisisombululo se-viscous. Kufuneka kuqatshelwe ukuba i-agent ye-antifungal kufuneka yongezwe kumama otywala ngokukhawuleza.
3. Kwiphenology yesidudu: Ekubeni izinyibilikisi zendalo zizinyibilikisi ezihlwempuzekileyo ze-hydroxyethyl cellulose, ezi zinyibilikisi zendalo zingasetyenziselwa ukulungisa isidudu. Ezona zinyibiliki zisetyenziswa ngokuqhelekileyo ezifana ne-ethylene glycol, ipropylene glycol, kunye ne-film-forming agents (ezifana ne-hexylene glycol okanye i-diethylene glycol butyl acetate), amanzi omkhenkce nawo asisinyibiliki esibi, ngoko ke amanzi omkhenkce adla ngokusetyenziswa kunye nolwelo oluphilayo. Ukulungiselela isidudu.
I-porridge efana ne-hydroxyethyl cellulose inokongezwa ngokuthe ngqo kwipeyinti. I-hydroxyethyl cellulose idumbe ngokupheleleyo kwisidudu. Xa ifakwe kwipeyinti, iyachithwa ngokukhawuleza kwaye iyancipha. Emva kokongeza, kufuneka iqhutywe ngokuqhubekayo de i-hydroxyethyl cellulose ichithwe ngokupheleleyo kwaye ifane. Ngokuqhelekileyo, i-porridge ixutywe kunye neengxenye ezintandathu ze-organic solvent okanye amanzi e-ice kunye nenxalenye enye ye-hydroxyethyl cellulose. Emva kwemizuzu emi-5 ukuya kwengama-30, i-hydroxyethyl cellulose iya kwenziwa i-hydrolyzed kwaye idumbe ngokucacileyo. Ehlotyeni, ukufuma kwamanzi ngokubanzi kuphezulu kakhulu, kwaye akufanelekanga ukusetyenziselwa isidudu.
4. Imiba efuna ingqwalasela xa kulungiswa utywala lukamama lwe-hydroxyethyl cellulose
Ekubeni i-hydroxyethyl cellulose i-powder ecutshungulwayo, kulula ukuyiphatha kunye nokuchithwa emanzini nje ngokuba kuphawulwe le mibandela elandelayo.
1) Ngaphambi nangemva kokongeza i-hydroxyethyl cellulose, kuyimfuneko ukuqhubeka uvuselela de isisombululo sibonakale ngokucacileyo kwaye sicacile.
I-2) Kufuneka ihlulwe kwi-barrel yokuxuba ngokukhawuleza, kwaye ungafaki i-cellulose ye-hydroxyethyl eyenziwe yaba ngamaqhuma okanye iibhola ngqo kwi-barrel yokuxuba.
I-3) Ukushisa kwamanzi kunye nexabiso le-pH emanzini linobudlelwane obubalulekileyo kunye nokuchithwa kwe-hydroxyethyl cellulose, ngoko ke ingqwalasela ekhethekileyo kufuneka ihlawulwe kuyo.
4) Musa ukongeza ezinye izinto ze-alkaline kumxube ngaphambi kokuba i-hydroxyethyl cellulose powder ifakwe emanzini. Ukunyusa i-pH kuphela emva kokumanzisa kuya kunceda ekunyibilikeni.
I-5) Ngokusemandleni, yongeza i-agent ye-antifungal ngokukhawuleza.
6) Xa usebenzisa i-high-viscosity hydroxyethyl cellulose, ukuxinwa kotywala komama akufanele kube ngaphezu kwe-2.5-3% (ngobunzima), ngaphandle koko utywala omama kuya kuba nzima ukuphatha.
