Iipropati ze-Hydroxyethyl cellulose (HEC) kunye nokusetyenziswa

Njengomntu osebenza nge-non-ionic,i-hydroxyethyl cellulose(HEC) inezi mpawu zilandelayo ukongeza ukujiya, ukuxhoma, ukubopha, ukudada, ukwenza ifilim, ukusasaza, ukugcina amanzi kunye nokubonelela ngeecolloids ezikhuselayo:

1. I-HEC iyancibilika kumanzi ashushu okanye abandayo, kwaye ayigqithisi kwiqondo lokushisa eliphezulu okanye ukubilisa, ngoko inoluhlu olubanzi lwe-solubility kunye neempawu ze-viscosity, kunye ne-gelation engekho-thermal;

2. I-non-ionic ngokwayo ingahlala kunye nezinye iipolymers ezinamanzi, i-surfactants kunye neetyuwa kuluhlu olubanzi, kwaye i-colloidal thickener egqwesileyo equlethe izisombululo eziphezulu ze-electrolyte;

3. Umthamo wokugcinwa kwamanzi uphindwe kabini kunalowo we-methyl cellulose, kwaye unolawulo olungcono lokuhamba.

4. Xa kuthelekiswa ne-methyl cellulose eyaziwayo kunye ne-hydroxypropyl methyl cellulose, ikhono lokusabalalisa i-HEC libi kakhulu, kodwa ikhono lokukhusela i-colloid linamandla.

Uyisebenzisa njani i-hydroxyethyl cellulose? 

1. Joyina ngokuthe ngqo kwimveliso

1. Yongeza amanzi acocekileyo kwibhakethi enkulu exhotywe nge-blender ephezulu yokucheba.

2. Qala ukuvuselela ngokuqhubekayo ngesantya esiphantsi kwaye ucofe i-hydroxyethyl cellulose kwisisombululo ngokulinganayo.

3. Qhubeka uvuselela de onke amasuntswana afakwe emanzini.

4. Emva koko yongeza i-arhente yokukhusela umbane, izongezo ze-alkaline ezifana ne-pigments, i-dispersing aids, amanzi e-ammonia.

5. Gxuma de yonke i-cellulose ye-hydroxyethyl ichithwe ngokupheleleyo (i-viscosity yesisombululo iyanda kakhulu) ngaphambi kokuba ungeze amanye amacandelo kwifomula, kwaye ugaye ide ibe yinto.
