I-Hydroxyethyl cellulose (HEC) izakhiwo nokusetshenziswa

Njengomuntu osebenza ngaphansi kwe-non-ionic,i-hydroxyethyl cellulose(HEC) inalezi zakhiwo ezilandelayo ngaphezu kokujiya, ukumisa okwesikhashana, ukubopha, ukuntanta, ukwenza ifilimu, ukusabalalisa, ukugcina amanzi kanye nokuhlinzeka ngama-colloid avikelayo:

1. I-HEC iyancibilika emanzini ashisayo noma abandayo, futhi ayidli ngokushisa okuphezulu noma ukubilisa, ngakho-ke inohlu olubanzi lwezimpawu ze-solubility kanye ne-viscosity, kanye ne-gelation engashisi;

2. I-non-ionic ngokwayo ingahlala namanye ama-polymers ancibilikayo emanzini, ama-surfactants nama-salts ebangeni elibanzi, futhi iyi-colloidal thickener enhle kakhulu equkethe izixazululo ze-electrolyte eziphezulu zokugxila;

3. Umthamo wokugcina amanzi uphakeme ngokuphindwe kabili kunalowo we-methyl cellulose, futhi unokulawula ukugeleza okungcono.

4. Uma kuqhathaniswa ne-methyl cellulose eyaziwayo kanye ne-hydroxypropyl methyl cellulose, ikhono lokuhlakaza le-HEC libi kakhulu, kodwa ikhono le-colloid lokuvikela liqine kakhulu.

Ungayisebenzisa kanjani i-hydroxyethyl cellulose? 

1. Joyina ngokuqondile ekukhiqizeni

1. Faka amanzi ahlanzekile ebhakedeni elikhulu elifakwe i-blender high-shear.

2. Qala ukunyakazisa ngokuqhubekayo ngesivinini esiphansi bese uhlunga kancane kancane i-hydroxyethyl cellulose esixazululweni ngokulinganayo.

3. Qhubeka ugqugquzela kuze kube yilapho zonke izinhlayiya sezicwile.

4. Bese wengeza i-ejenti yokuvikela umbani, izithasiselo ze-alkaline ezifana nezingulube, izinsiza ezihlakazayo, amanzi e-ammonia.

5. Hlanganisa kuze kube yilapho yonke i-hydroxyethyl cellulose ichitheka ngokuphelele (i-viscosity yesisombululo ikhula kakhulu) ngaphambi kokwengeza ezinye izingxenye kufomula, futhi ugaye kuze kube yilapho
