Ukubambelela kwayo kuvumela i-HPC ukuba isetyenziswe njenge-binder kwiipilisi zokuqinisekisa ukuba iipilisi zigcina ingqibelelo kwaye zibe nobunzima obufanelekileyo ngexesha lenkqubo yokuvelisa. Ukongeza, i-HPC inokuphucula ukunamathela kweziyobisi kwindlela yesisu kunye nokuphucula ukufumaneka kweziyobisi.
5. Ukuzinza okuphezulu
I-Hydroxypropyl cellulose inozinzo oluhle ekukhanyeni, ukushisa kunye ne-oxygen, ngoko ayiyi kubola ngokukhawuleza xa igcinwe phantsi kweemeko eziqhelekileyo. Oku kuzinza okuphezulu kwenza i-HPC igcine ukusebenza kwayo ngexesha lokugcinwa kwexesha elide kunye nokwandisa ubomi beshelufu yemveliso, ebaluleke kakhulu ekusebenziseni izimonyo kunye neemveliso zamachiza.
6. Iimpawu ezilungileyo ze-rheological kunye nefuthe lokuqina
I-HPC ineempawu ezibalaseleyo zerheological kwaye ingasetyenziswa njenge-thickener kunye ne-rheology modifier. Isetyenziswa ngokubanzi kwiingubo, ukutya kunye nezithambiso. Ngokomzekelo, kwii-cosmetics, i-HPC inokunyusa i-viscosity ye-emulsions, i-gels okanye i-pastes, kunye nokuphucula ukuthungwa kunye nokuvakalelwa kwemveliso. Kwishishini lokutya, i-HPC isetyenziselwa i-emulsifier kunye ne-stabilizer ukukhusela ukuhlukana kwezithako zokutya kunye nokuphucula ukuzinza kunye nokunambitha kokutya.
7. Usetyenziso olubanzi
Ngenxa yeengenelo zayo ezininzi, i-hydroxypropyl cellulose isetyenziswa kakhulu kumashishini amaninzi:
Umzi-mveliso wamachiza: usetyenziswa njenge-binder, i-disintegrant, i-ejenti yokwambathisa kunye ne-stabilizer kwiipilisi, ii-capsules, kunye neefom zedosi elawulwayo.
Ishishini lokutya: lisetyenziswa njenge-thickener, emulsifier kunye nefilimu etyiwayo ekutyeni okucutshungulweyo, izigcina-lwazi kunye neemveliso ezifakwe emulsified.
