Nezve nzira yehunyanzvi yekushandisa inogamuchirwa nezvigadzirwa zvemakemikari, zvinodikanwa kukwezva kutarisisa uye kutarisisa kune wese anoshanda anoshanda, nekuti iyi ndiyo kiyi yekuita sarudzo kunobudirira uye kupedzisa kwega kwega chirongwa chekuvaka.Kana iyo nzira yekuigadzira inogona kukanganisa zvakanyanya kushandiswa kwakachengeteka kwechigadzirwa, semuenzaniso, hydroxypropyl methylcellulose, iyo parizvino yakakurumbira munzvimbo dzakasiyana siyana, ngatitarisei pamwe pazasi.
Kuchengetwa kwemvura kwemethylcellulose kunoenderana nehuwandu hwayo hwekuwedzera, viscosity, particle fineness uye dissolution rate.Kazhinji, kana huwandu hwekuwedzera hwakakura, hunyoro hudiki, uye viscosity yakakura, mwero wekuchengetedza mvura wakakwira.Pakati pavo, huwandu hwekuwedzera hune simba guru pahuwandu hwekuchengetedza mvura, uye chiyero che viscosity hachina kuenzana zvakananga nehuwandu hwekuchengetedza mvura.Mwero wekunyungudika unonyanya kuenderana nehuwandu hwekugadziriswa kwepasi kwe cellulose particles uye particle fineness.Pakati pema cellulose ethers ari pamusoro, methyl cellulose uye hydroxypropyl methyl cellulose vane mwero wepamusoro wekuchengetedza mvura.
Methylcellulose inonyungudika mumvura inotonhora, uye zvichave zvakaoma kunyungudika mumvura inopisa.Mushonga wayo une aqueous wakanyatsogadzikana muhupamhi hwepH = 3 ~ 12.Iine kuwirirana kwakanaka ne starch, guar gum, nezvimwewo uye akawanda surfactants.Kana tembiricha inosvika tembiricha yegelation, gelation inoitika.
Panyaya yekushandiswa chaiko kwehydroxypropyl methylcellulose yatakaunza kwauri pamusoro, zvinodikanwa kukwezva kutarisisa uye kutarisa kune wese anoshanda, kuitira kuti uve nechokwadi chekushanda kweichi chigadzirwa chemakemikari.
