1. Joyina ngokuqondile ngesikhathi sokukhiqiza
1. Faka amanzi ahlanzekile ebhakedeni elikhulu elifakwe i-blender high-shear.
2. Qala ukunyakazisa ngokuqhubekayo ngesivinini esiphansi bese usihlunga kancane kancane i-hydroxyethyl cellulose esixazululweni ngokulinganayo.
3. Qhubeka ugqugquzela kuze kube yilapho zonke izinhlayiya sezicwile.
4. Bese wengeza ama-antifungal agents, izithasiselo ze-alkaline ezifana nezingulube, izinsiza ezihlakazayo, amanzi e-ammonia.
5. Hlanganisa kuze kube yilapho yonke i-cellulose ye-hydroxyethyl ichitheka ngokuphelele (i-viscosity yesisombululo ikhula kakhulu) ngaphambi kokwengeza ezinye izingxenye kufomula, futhi ugaye kuze kube umkhiqizo ophelile.
2. Ihlonyiswe ngotshwala kamama bokulinda
Le ndlela iwukuba kuqala ulungise utshwala omama ngokugxila okuphezulu, bese uyifaka kupende we-latex.Inzuzo yale ndlela yukuthi inokuguquguquka okukhulu futhi ingafakwa ngokuqondile kupende ophelile, kodwa kufanele igcinwe kahle.Izinyathelo zifana nezinyathelo 1-4 endleleni 1, ngaphandle kokuthi ukugqugquzela okuphezulu akudingekile ukuhlakazeka ngokuphelele kusixazululo se-viscous.
3.Ilungiselelwe ephalishini ukuze lisetshenziswe
Njengoba izincibilikisi zemvelo ziyizincibilikisi ezimpofu ze-hydroxyethyl cellulose, lezi zinyibilikisi zemvelo zingasetshenziswa ukulungisa imikhiqizo efana nephalishi.Izincibilikisi eziphilayo ezisetshenziswa kakhulu uketshezi lwemvelo ekwenziweni kopende okufana ne-ethylene glycol, i-propylene glycol nama-filmforms (isb. i-ethylene glycol noma i-diethylene glycol butyl acetate).Amanzi eqhwa nawo awasincibilikisi esibi, ngakho-ke amanzi eqhwa avame ukusetshenziswa kanye noketshezi oluphilayo ukuze kulungiswe imikhiqizo efana nephalishi.Umkhiqizo ofana nephalishi, i-hydroxyethyl cellulose, ungangezwa ngokuqondile kupende, futhi i-hydroxyethyl cellulose ikhiqizwe futhi yavuvukala yiphalishi.Uma yengezwe kupende, iyancibilika ngokushesha futhi ishube.Ngemuva kokwengeza, kusadingeka ukuthi uqhubeke ugqugquzela kuze kube yilapho i-hydroxyethyl cellulose ichitheka ngokuphelele futhi iyunifomu.Ngokuvamile, umkhiqizo ofana nephalishi uxutshwa nezingxenye eziyisithupha ze-organic solvent noma amanzi eqhwa kanye nengxenye eyodwa ye-hydroxyethyl cellulose.Ngemuva kwemizuzu engaba ngu-6-30, i-hydroxyethyl cellulose izokwenziwa i-hydrolyzed futhi ivuvuke ngokusobala.Ehlobo, izinga lokushisa lamanzi ngokuvamile liphezulu kakhulu, futhi akufanelekile ukusebenzisa imikhiqizo efana nephalishi.
