IHydroxy Propyl Methyl Cellulose (HPMC) sisithako esiqhelekileyo esisetyenziswa ekuqulunqweni kwepeyinti kunye neengubo. Yipolymer enyibilikayo emanzini esebenza njenge-thickener, i-rheology modifier, kunye ne-binder kwimiqulu yepeyinti.

Nazi ezinye zeendlela i-HPMC esetyenziswa ngayo kwipeyinti:

1. Ukuphucula i-viscosity: I-HPMC isetyenziswa njenge-thickener yokwandisa i-viscosity yepeyinti. Oku kunceda ukuthintela ukuhlalisa kunye nokuncipha, kwaye kunokuphucula ukukhululeka kwesicelo.
2. Ukuphucula ukusebenza: I-HPMC inokuphucula ukusebenza kwepeyinti ngokubonelela ngokusemgangathweni, ukusabalalisa, kunye neempawu zokuhamba. Oku kunokukhokelela ekugqityweni okugudileyo kwaye ngakumbi.
3. Ukulawula ukugcinwa kwamanzi: I-HPMC inokunceda ukulawula ukugcinwa kwamanzi epeyinti ngokufunxa amanzi kunye nokuwakhulula ngokucothayo ekuhambeni kwexesha. Oku kunokunceda ukuthintela ukuqhekeka kunye nokuphucula ukuqina kwepeyinti.
4. Ukubonelela ngeempawu ezibophelelayo: I-HPMC inokusebenza njengesibophelelo kwiindlela zepeyinti, inceda ukubopha i-pigment kunye nezinye izithako kunye. Oku kunokuphucula ukubambelela kunye nokuqina kwepeyinti.
5. Ukunciphisa amagwebu: I-HPMC inokunceda ukunciphisa ubuninzi be-foam eveliswa ngexesha lokuxuba kunye nokusetyenziswa kwepeyinti. Oku kunokuphucula ukubonakala kwepeyinti kunye nokunciphisa ixesha elifunekayo lokulungiswa kwendawo.

Ngokubanzi, i-HPMC sisithako esiluncedo ekuqulunqweni kwepeyinti kunye neengubo. Iimpawu zayo zinokunceda ekuphuculeni ukusebenza kunye nokubonakala kwepeyinti, okwenza kube yinto ekhethwayo kwishishini.
