Dab tsi yog qhov viscosity yam ntxwv ntawm hydroxypropyl methyl cellulose aqueous kua?
Hydroxypropyl methyl cellulose muaj lub zeem muag dav hauv kev tsim kho kev lag luam, thiab nws cov thickening zoo heev thiab dej tuav cov khoom ua rau nws daim ntawv thov hauv kev tsim kho kev lag luam tsis tuaj yeem tsis quav ntsej.Tab sis peb paub ntau npaum li cas txog nws qhov zoo tshaj?Tam sim no cia peb tham txog cov viscosity ntawm hydroxypropyl methyl cellulose aqueous kua.
Hydroxypropyl methyl cellulose aqueous tov cov lus qhia yooj yim: Lus Askiv luv HPMC non-ionic, dej-soluble cellulose ether, cov tsos ntawm dawb los yog lub teeb daj hmoov los yog granular khoom.Nws saj tsis qab, tsis muaj ntxhiab, tsis muaj tshuaj lom, ruaj khov khoom ntawm cov khoom hauv dej los tsim cov kua nplaum me ntsis pob tshab.
Dab tsi yog qhov cuam tshuam rau viscosity ntawm hydroxypropyl methyl cellulose aqueous kua?
1.Kev sib raug zoo nrog polymer: viscosity ntawm hydroxypropyl methyl cellulose aqueous tov yog proportional rau lub polymer los yog molecular hnyav, thiab nce nrog kev txhim kho ntawm polymerization degree.Cov nyhuv no yog pom tseeb dua nyob rau hauv cov ntaub ntawv ntawm tsawg polymerization dua nyob rau hauv cov ntaub ntawv ntawm siab polymerization.
2.Kev sib raug zoo ntawm viscosity thiab concentration: lub viscosity ntawm hydroxypropyl methyl cellulose nyob rau hauv aqueous tov nce nrog cov concentration ntawm aqueous tov, thiab txawm ib tug me me concentration hloov yuav ua rau ib tug loj hloov nyob rau hauv viscosity.
3.Kev sib raug zoo ntawm viscosity thiab shear npaum li cas: Qhov kev ntsuam xyuas qhia tau hais tias hydroxypropyl methyl cellulose tsis muaj qhov hloov pauv loj ntawm qhov qis qis, thiab cov viscosity txo qis nrog qhov nce ntawm shear npaum li cas.
4.Kev sib raug zoo ntawm viscosity thiab kub: hydroxypropyl methyl cellulose cuam tshuam rau qhov kub thiab txias, thiab viscosity txo qis nrog qhov kub thiab txias.
5.Lwm yam: viscosity ntawm hydroxypropyl methyl cellulose thiab ntau yam additives, kev daws teeb meem, PH qhov tseem ceeb kuj muaj kev cuam tshuam.
Thaum peb ua qhov kuaj sim peb xav paub txog qhov viscosity yam ntxwv ntawm hydroxypropyl methyl cellulose aqueous kua?
