Iyo dispersibility yecarboxymethyl cellulose ndeyokuti chigadzirwa chacho chichasvibiswa mumvura, saka kupararira kwechigadzirwa kwavewo nzira yekutonga kushanda kwayo.Ngatidzidze zvakawanda nezvazvo:
1) Imwe huwandu hwemvura inowedzerwa kune yakawanikwa dispersion system, iyo inogona kuvandudza dispersibility yecolloidal particles mumvura, uye zvinodikanwa kuve nechokwadi kuti huwandu hwemvura yakawedzerwa haigone kunyungudutsa colloid.
2) Izvo zvinodikanwa kuparadzira zvimedu zvecolloidal mumvura inotakura inosanganiswa mumvura, isinganyungudika mumvura-inonyungudika gels kana isina mvura, asi inofanira kunge yakakura kudarika huwandu hwemakolloidal particles kuitira kuti akwanise kuparadzirwa zvizere. .zvinwiwa zvemonohydric senge methanol uye ethanol, ethylene glycol, acetone, nezvimwe.
3) Munyu unonyungudika nemvura unofanirwa kuwedzerwa kumvura inotakura, asi munyu haugoni kuita ne colloid.Basa rayo guru nderokudzivirira gel-soluble gel kubva pakugadzira paste kana coagulating uye kunaya kwemvura painozorora.Inonyanya kushandiswa ndeye sodium chloride uye zvichingodaro.
4) Izvo zvinodikanwa kuwedzera mumiriri wekumisa kune inotakura mvura kudzivirira chiitiko chekunaya kwegel.Iyo huru yekumisa mumiriri inogona kuva glycerin, hydroxypropyl methylcellulose, nezvimwewo. Iyo inomisa mumiriri inofanira kuve yakanyungudika mumutakuri wemvura uye inowirirana necolloid.Kune carboxymethyl cellulose, kana glycerol ikashandiswa semumiriri wekumisa, iyo yakajairika dosi inenge 3% -10% yemvura inotakura.
5) Mukuita kwe alkalization uye etherification, cationic kana nonionic surfactants inofanira kuwedzerwa, uye inofanira kunyungudutswa mumutakuri wemvura kuti ienderane nemacolloids.Inowanzo shandiswa surfactants lauryl sulfate, glycerin Monoester, propylene glycol fatty acid ester, dosage yayo inenge 0.05% -5% yemvura inotakura.
