I-Hydroxyethyl cellulose iyi-polymer engancibiliki emanzini engeyona i-ionic eyenziwe nge-cellulose, into engokwemvelo ye-polymer, ngochungechunge lwezinqubo zamakhemikhali. Kuyinto eqinile emhlophe noma ephuzi, engenaphunga futhi engenambitheki, engancibilika emanzini abandayo namanzi ashisayo, futhi izinga lokuchithwa liyakhula ngokunyuka kwezinga lokushisa. Ngokuvamile, ayincibiliki ezincibilikisini eziningi eziphilayo. Isetshenziswa njenge-thickener kanye ne-stabilizer kupende we-latex. Kulula ukuhlakazeka emanzini abandayo anenani le-pH elingaphansi noma elilingana no-7, kodwa kulula ukuhlanganisa oketshezini lwe-alkali, ngakho-ke ngokuvamile lulungiswa kusengaphambili ukuze lusetshenziswe kamuva, noma amanzi abuthakathaka ane-asidi noma isixazululo se-organic senziwa udaka. , futhi ingabuye ihlanganiswe nezinye i-granular Izithako zomile zixutshwe ndawonye.
Izici ze-hydroxyethyl cellulose:
I-HEC iyancibilika emanzini ashisayo noma abandayo, futhi ayidli ngokushisa okuphezulu noma ukubilisa, okwenza ibe nohlu olubanzi lokuncibilika kanye nezici ze-viscosity, kanye ne-gelation engashisi.
Ingahlala kanye nohlu olubanzi lwama-polymers ancibilika emanzini, ama-surfactants, nosawoti, futhi iyi-colloidal thickener enhle kakhulu yezixazululo eziqukethe ama-electrolyte agxile kakhulu.
Umthamo wokugcina amanzi uphakeme ngokuphindwe kabili kunalowo we-methyl cellulose, futhi unokulawula ukugeleza okungcono.
Uma kuqhathaniswa ne-methyl cellulose eyaziwayo kanye ne-hydroxypropyl methyl cellulose, ikhono lokuhlakaza le-HEC libi kakhulu, kodwa ikhono le-colloid lokuvikela linamandla kakhulu.
Ukwakhiwa okuhle kakhulu; inezinzuzo zokonga umsebenzi, akulula ukuconsa, i-anti-sag, i-anti-splash enhle, njll.
Ukuhambisana okuhle nama-surfactants ahlukahlukene kanye nama-preservatives asetshenziswa kupende we-latex.
I-viscosity yokugcina izinzile, engavimbela i-cellulose ye-hydroxyethyl evamile ekunciphiseni i-viscosity kapende we-latex ngesikhathi sokugcinwa ngenxa yokubola kwama-enzyme.
