Carboxymethyl cellulose (Carboxymethyl cellulose) inoumbwa nekuita kweboka rehydroxyl reanhydroglucose unit pane cellulose chain ne etherification group (chloro Z acid kana ethylene oxide);
Icho chinhu chisina ruvara amorphous chinonyungudutswa mumvura, aqueous alkali solution, ammonia uye cellulose solution, isingagadziriswi mu organic solution uye mineral oil; inogona kushandiswa senge saizi, calendering uye thickening mumiriri muindasitiri yemachira;
Kugadzira mumiririri mukugadzira mapepa uye bhodhi;
Kudzoreredzwa kwetsvina mune zvekugadzira zvekuchenesa agents;
Flotation mumiririri wekusarudza mhangura-nickel uye potassium ore;
Viscous suspension thickener uye stabilizer paunenge uchichera mafuta uye gasi matsime;
glue kuumbwa kwemapuranga;
yakaoma kuvaka musanganiswa zvikamu;
Mvura latex pendi zvikamu, nezvimwe.
Hydroxypropyl methylcellulose (Hypromellose, Cellulose) inogadzirwa necotton cellulose yakanyanya kuchena sechinhu chakabikwa, icho chakanyanya etherified pasi pemamiriro ealkaline, uye haina chero zvinhu zvinoshanda senge nhengo dzemhuka nemafuta. Inonyungudika mumvura uye yakawanda polar uye yakafanira zvikamu zve ethanol / mvura, propanol / mvura, dichloroethane, nezvimwewo, isinganyunguriki mu ether, acetone, uye absolute ethanol, uye inoputika kuva yakajeka kana zvishoma turbid colloidal solution mumvura inotonhora. Mushonga wemvura une basa repamusoro, kujeka kwepamusoro uye kushanda kwakagadzikana.
HPMC ine pfuma ye thermal gelation. Chigadzirwa cheaqueous solution chinopisa kuti chigadzire gel uye chinonaya, uye chinopera mushure mekutonhora. Iyo tembiricha yegelation yemhando dzakasiyana dzakasiyana. Solubility inosiyana ne viscosity. Iyo yakaderera viscosity, iyo yakakura solubility. Madiro akasiyana eHPMC ane mimwe misiyano mumidziyo yavo. Kunyungudika kweHPMC mumvura hakukanganiswe neiyo pH kukosha.
