1. Engeza ngokuqondile lapho ugaya i-pigment: Le ndlela ilula kakhulu futhi ithatha isikhathi esincane. Izinyathelo ezinemininingwane zimi kanje:
(1) Engeza amanzi ahlanzekile afanelekile ku-vat ye-agitator esike kakhulu (ngokuvamile, i-ethylene glycol, i-ejenti yokumanzisa kanye ne-ejenti eyenza ifilimu konke kwengezwa ngalesi sikhathi)
(2) Qala ukunyakazisa ngokuqhubekayo ngesivinini esiphansi bese wengeza kancane i-hydroxyethyl cellulose
(3) Qhubeka ugqugquzela kuze kube yilapho zonke izinhlayiya sezicwile
(4) Engeza i-ejenti ye-antifungal, isilungisi se-PH, njll.
(5) Hlanganisa kuze kube yilapho yonke i-cellulose ye-hydroxyethyl ichitheka ngokuphelele (i-viscosity yesixazululo ikhula kakhulu) ngaphambi kokwengeza ezinye izingxenye kufomula, futhi ugaye kuze kube yilapho iba upende.
2. Lungiselela utshwala bukamama ukuze babusebenzise: Le ndlela iwukulungiselela ugologo kamama ngokugxila kakhulu kuqala, bese ubufaka kupende we-latex. Inzuzo yale ndlela yukuthi inokuguquguquka okukhulu futhi ingafakwa ngokuqondile kupende ophelile, kodwa kufanele igcinwe kahle. Izinyathelo nezindlela ziyafana nezinyathelo (1)-(4) kuNdlela 1, umehluko ukuthi asikho isidingo se-high-shear agitator, futhi amanye ama-agitator anamandla anele ukugcina imicu ye-hydroxyethyl ihlakazeke ngokufanayo isixazululo zisetshenziswa. Angakwazi. Qhubeka ugqugquzela njalo kuze kube yilapho uncibilika ngokuphelele kusixazululo se-viscous. Kumele kuqashelwe ukuthi i-ejenti ye-antifungal kufanele yengezwe kugologo kamama ngokushesha ngangokunokwenzeka.
3. Ngephenology yephalishi: Njengoba izincibilikisi zemvelo ziyizincibilikisi ezimpofu ze-hydroxyethyl cellulose, lezi zinyibilikisi zemvelo zingasetshenziswa ukulungisa iphalishi. Izinyibilikisi ezisetshenziswa kakhulu eziphilayo ezifana ne-ethylene glycol, i-propylene glycol, nama-ejenti akha ifilimu (njenge-hexylene glycol noma i-diethylene glycol butyl acetate), amanzi e-ice nawo awasincibilikisi esingesihle, ngakho-ke amanzi e-ice ngokuvamile asetshenziswa kanye noketshezi oluphilayo. Ukulungisa iphalishi.
I-hydroxyethyl cellulose efana nephalishi ingafakwa ngokuqondile kupende. I-hydroxyethyl cellulose isivuvukele ngokuphelele ephalishini. Uma yengezwe kupende, iyancibilika ngokushesha futhi ishube. Ngemuva kokwengeza, kufanele inyakaziswe ngokuqhubekayo kuze kube yilapho i-hydroxyethyl cellulose ichitheka ngokuphelele futhi ifana. Ngokuvamile, iphalishi lixutshwe nezingxenye eziyisithupha ze-organic solvent noma amanzi eqhwa kanye nengxenye eyodwa ye-hydroxyethyl cellulose. Ngemva kwemizuzu emi-5-30, i-hydroxyethyl cellulose izokwenziwa i-hydrolyzed futhi ivuvuke ngokusobala. Ehlobo, umswakama wamanzi ajwayelekile uphakeme kakhulu, futhi awufaneleki ukusetshenziselwa iphalishi.
4. Izindaba ezidinga ukunakwa lapho kulungiswa utshwala bukamama be-hydroxyethyl cellulose
Njengoba i-hydroxyethyl cellulose iyimpushana ecutshungulwayo, kulula ukuyiphatha nokuchithwa emanzini inqobo nje uma lezi zindaba ezilandelayo ziphawulwa.
1) Ngaphambi nangemva kokwengeza i-hydroxyethyl cellulose, kuyadingeka ukuthi uqhubeke uvuselela kuze kube yilapho isixazululo sisobala ngokuphelele futhi sicacile.
2) Kumele ihlungwe emgqonyeni wokuxuba kancane kancane, futhi ungafaki i-hydroxyethyl cellulose eyakheke yaba izigaxa noma amabhola ngqo emgqonyeni wokuxuba.
3) Izinga lokushisa lamanzi kanye nenani le-pH emanzini linobudlelwano obubalulekile nokuqedwa kwe-hydroxyethyl cellulose, ngakho-ke kufanele kuqashelwe ngokukhethekile.
4) Ungafaki izinto ezine-alkali engxubeni ngaphambi kokuba i-hydroxyethyl cellulose powder ifakwe emanzini. Ukwenyusa i-pH kuphela ngemuva kokumanzisa kuzosiza ekuncibilikeni.
5) Ngokusemandleni akho, engeza i-ejenti ye-antifungal ngokushesha ngangokunokwenzeka.
6) Uma usebenzisa i-high-viscosity hydroxyethyl cellulose, ukuhlushwa kotshwala kamama akufanele kube ngaphezu kuka-2.5-3% (ngesisindo), ngaphandle kwalokho utshwala bomama buyoba nzima ukuphatha.
