Taw qhia:
Hydroxypropyl methyl cellulose (HPMC) yog ib hom ntawm nonionic polymer, uas ua los ntawm ntuj polymer cellulose li cov khoom siv raw. Cov khoom lag luam tsis muaj ntxhiab, tsis qab, tsis muaj tshuaj lom rau tus kheej xim hmoov, tuaj yeem yaj mus rau hauv dej txias los ua cov kua roj ua kom pom tseeb, nrog cov nplaim nplaum, ua kom haum, tawg, tawg, emulsification, zaj duab xis, ncua kev kawm, adsorption, gelling, ua si saum npoo, ya raws kev ceev thiab kev tiv thaiv ntawm colloid thiab lwm yam ntxwv.
Khoom nta:
1, Cov khoom nyoos ntuj tsim, tsis tshua muaj siab, ua haujlwm me me, kev nyab xeeb thiab kev tiv thaiv ib puag ncig;
2, dej solubility thiab thickening: tuaj yeem sai sai hauv cov dej txias, yaj hauv qee cov kuab tshuaj organic thiab dej thiab cov kuab tshuaj sib xyaw ua ke;
3, ntom nti thiab viscosity: ib qho me me ntawm yaj los tsim cov pob tshab kua, cov siab dua, kev ua haujlwm ruaj khov, kev tiv thaiv kev sib txawv nrog cov viscosity, qis viscosity, ntau dua solubility; Txhim kho qhov ntws los ruaj khov ntawm cov kab ke;
4, ntsev tsis kam: HPMC yog cov tshuaj tsis-polymeric, kuj ruaj khov hauv cov dej ntawm cov hlau ntsev lossis organic electrolyte;
5, kev ua haujlwm saum npoo: cov kua aqueous ntawm cov khoom muaj cov haujlwm saum npoo, nrog emulsification, tiv thaiv ntawm colloid thiab tus txheeb ze ruaj khov thiab lwm yam haujlwm thiab kev ua haujlwm; Thaj tsam nro: 2% tshuaj aqueous 42 ~ 56dN / cm;
6, pH ruaj khov: viscosity ntawm aqueous tov yog ruaj khov nyob rau hauv thaj tsam ntawm pH 3.0-11.0;
7, dej cia cov nyhuv: HPMC hydrophilic muaj peev xwm, ntxiv rau slurry, muab tshuaj txhuam, muab tshuaj txhuam cov khoom kom tswj tau cov dej siab ceev cov nyhuv;
8, kub ceev gelation: dej tov rhuab mus rau tej yam kub ua opaque, kom txog rau thaum tsim ntawm (poly) flocculation xeev, kom cov tshuaj poob viscosity. Tab sis thaum nws txias nws yuav rov qab mus rau nws qhov kev daws teeb meem qub. Qhov ntsuas kub ntawm qhov twg gelation tshwm sim nyob ntawm seb cov khoom lag luam, kev ntsuas ntawm qhov kev daws, thiab qhov ntsuas cua sov.
9, lwm yam ntxwv: kev tsim cov yeeb yaj kiab zoo, nrog rau ntau qhov ntawm cov enzyme tsis kam, cov yam ntxwv tawg thiab cov yam ntxwv.
Cim npe nrov: hydroxypropyl methyl cellulose thickeners, Tuam Tshoj, cov chaw muag khoom, cov chaw lag luam, yuav, ntau, nqe, hauv Tshuag
