Hydroxypropyl methyl selulose (HPMC) ifite umubyimba mwiza kandi irashobora gukoreshwa nka beto nziza yo kurwanya.HPMC yakoreshejwe cyane mubikorwa byubwubatsi.Ikizamini cyo kurwanya ikwirakwizwa Anti-dispersant nigipimo cyingenzi cya tekiniki yo gupima ubuziranenge bwa anti-dispersant.
HPMC ni amazi ya elegitoronike ya polymer, azwi kandi ku izina rya soluble resin cyangwa polymer soluble polymer, ni ukongera ubuvanganzo bw’amazi avanze wongera ubwiza bwuruvange, ni ibikoresho bya hydrophilique polymer, bishobora gushonga mumazi bigashiraho igisubizo cyangwa gutatanya.Birashobora kugaragara ko mugihe ingano ya naphthalene ikurikirana neza igabanya amazi neza, kwinjiza ibikoresho bigabanya amazi bizagabanya kurwanya ikwirakwizwa rya sima ivanze.
Ni ukubera ko sisitemu ya naphthalene ikora neza igabanya amazi ni iy'ububasha, iyo kugabanya amazi byongewe kuri minisiteri, kugabanya amazi mu buso bwa sima hejuru yuburinganire bumwe, kwanga amashanyarazi bituma ibice bya sima bigira imiterere ya flokculasiyo iratandukanye, amazi yarekuwe mumiterere, bizatera igice cyo gutakaza amazi ya sima.Muri icyo gihe, hamwe no kwiyongera kwa HPMC kuvanga, gukwirakwiza minisiteri nshya ya sima nibyiza kandi byiza.
