Njenge-ejenti yokumisa kanye ne-thickener, ithuthukisa ukufana kwe-glaze slurry, ivimbela ukuna kwe-glaze, futhi ithuthukisa ikhwalithi yobuso.

4. Ukucubungula ngepulasitiki kanye nemikhiqizo ye-polymer

I-HPMC ingasetshenziswa njengesithambisi sokubumba, i-ejenti yokukhulula, kanye ne-dispersant ekuphenduleni kwe-polymerization:

4.1. I-PVC, i-ABS kanye nokunye ukukhiqizwa kwepulasitiki

Isebenza njengesiqinisi sokuhlakaza enqubweni yokwenza i-polymerization yokumiswa ukuze isayizi wezinhlayiya ifane.

4.2. Imikhiqizo ebunjiwe

Nikeza ukuthambisa okuhle, vimbela imikhiqizo ukuthi inamathele esikhumbeni, futhi uthuthukise ukuqeda kwendawo.

5. Imboni yamakhemikhali yansuku zonke (imikhiqizo yezinga lezimboni)

Nakuba i-HPMC yezinga lokudla noma yezinga lemithi isetshenziswa kabanzi ekulungiseleleni ngomlomo, emkhakheni wamakhemikhali ansuku zonke, i-HPMC yezinga lezimboni isetshenziselwa imikhiqizo engathintani, njenge:

5.1. Insipho yokuwasha izingubo kanye noketshezi lokuwasha izitsha

Nikeza umphumela wokuqina osobala, uthuthukise ukuhambisana komkhiqizo, futhi uthuthukise ulwazi lomsebenzisi.

5.2. Iglue lodonga

Njengengxenye eyinhloko yokuqina nokwakha ifilimu, ithuthukisa ukusebenza kokubopha futhi yenza kube lula ukwakhiwa.

5.3. Uketshezi lokuwasha izimoto, amanzi engilazi

Thuthukisa ukunamathela futhi wandise isikhathi somphumela wokuhlanza.

6. Izinto zensimbi kanye nokushisela

Ekukhiqizweni kwezinduku zokushisela nama-electrode, i-HPMC isetshenziswa njenge-binder kanye ne-ejenti yokwakha ifilimu:

6.1. Ukwembozwa kwenduku yokushisela

Thuthukisa ukunamathelana phakathi kwempuphu nengaphakathi lensimbi futhi uthuthukise ukufana kwesembozo.

6.2. Izinto zokubumba zensimbi

I-HPMC ingasetshenziswa ekulinganisweni kobuso bephepha, ekumbozeni kanye nakwezinye izixhumanisi ukuthuthukisa ukumelana namafutha, ukuzivumelanisa nezimo kokuphrinta kanye nokushelela kwephepha.

10. Izinto ezinobungani nemvelo

Njenge-cellulose yemvelo evuselelekayo, i-HPMC isetshenziswa kabanzi ezintweni zokwakha eziluhlaza ezinobungani nemvelo, izinto zokupakisha zemvelo kanye neminye imikhakha.

I-Hydroxypropyl methylcellulose (HPMC) isibe yinto ewusizo kakhulu emikhiqizweni eminingi yezimboni ngesakhiwo sayo samakhemikhali esiyingqayizivele kanye nezakhiwo zayo ezinhle kakhulu zomzimba. Kungakhathaliseki ukuthi izinto zokwakha zendabuko noma izinto zesimanje ezinobungani nemvelo kanye nemboni ye-polymer, i-HPMC idlala indima ebalulekile. Ngokuthuthuka kwemboni yamakhemikhali aluhlaza kanye nezinto zokusebenza okuphezulu,ukusetshenziswa kwezimboni kwe-HPMCizokwandiswa kakhulu, futhi amandla ayo emakethe azoqhubeka nokukhula.
