Hydroxypropyl Methylcellulose (HPMC) yog cellulose derivative siv dav hauv zaub mov, tshuaj, kev tsim kho thiab tshuaj pleev ib ce. Nws cov qauv tshwj xeeb E15 tau nyiam ntau yam vim nws cov khoom tshwj xeeb thiab daim ntawv thov dav.
1. Lub cev thiab tshuaj muaj zog
Tshuaj muaj pes tsawg leeg
HPMC E15 yog ib feem methylated thiab hydroxypropylated cellulose ether, uas nws cov qauv molecular muaj hydroxyl pawg hauv cellulose molecule hloov los ntawm methoxy thiab hydroxypropyl pawg. Tus "E" nyob rau hauv tus qauv E15 sawv cev rau nws lub ntsiab siv raws li ib tug thickener thiab stabilizer, thaum "15" qhia nws viscosity specification.
Qhov tshwm sim
HPMC E15 feem ntau yog cov hmoov dawb lossis dawb dawb uas muaj ntxhiab tsw, tsis qab thiab tsis muaj tshuaj lom. Nws cov khoom yog zoo thiab yooj yim yaj nyob rau hauv dej txias thiab kub los ua ib tug pob tshab los yog me ntsis turbid tov.
Solubility
HPMC E15 muaj cov dej solubility zoo thiab tuaj yeem yaj sai sai hauv dej txias los tsim cov kev daws teeb meem nrog qee qhov viscosity. Cov tshuaj no tseem nyob ruaj khov ntawm qhov sib txawv ntawm qhov kub thiab txias thiab tsis yooj yim cuam tshuam los ntawm ib puag ncig sab nraud.
viscosity
E15 muaj ntau yam viscosity. Nyob ntawm nws cov kev siv tshwj xeeb, qhov xav tau viscosity tuaj yeem tau los ntawm kev kho qhov concentration thiab kev daws qhov kub thiab txias. Feem ntau hais lus, E15 muaj viscosity txog 15,000cps hauv 2% kev daws teeb meem, uas ua rau nws ua tau zoo hauv cov ntawv thov uas xav tau viscosity siab.
2. Kev ua haujlwm zoo
Thickening nyhuv
HPMC E15 yog cov thickener muaj txiaj ntsig zoo thiab tau siv dav hauv ntau lub tshuab dej. Nws tuaj yeem ua rau kom cov viscosity ntawm cov kua ua tau zoo, muab cov thixotropy zoo heev thiab kev ncua, thiab yog li txhim kho qhov kev ntxhib los mos thiab ruaj khov ntawm cov khoom.
Stabilizing nyhuv
E15 muaj kev ruaj ntseg zoo, uas tuaj yeem tiv thaiv cov sedimentation thiab agglomeration ntawm cov khoom nyob rau hauv lub dispersed system thiab tswj lub uniformity ntawm lub system. Nyob rau hauv lub emulsified system, nws muaj peev xwm stabilize cov roj-dej interface thiab tiv thaiv theem sib cais.
Cov cuab yeej ua yeeb yaj kiab
HPMC E15 muaj cov yeeb yaj kiab zoo heev thiab tuaj yeem tsim cov yeeb yaj kiab tawv, pob tshab ntawm qhov chaw ntawm ntau yam substrates. Cov yeeb yaj kiab no muaj qhov yooj yim thiab adhesion thiab yog siv dav hauv cov tshuaj txheej txheem, txheej txheej zaub mov, thiab cov txheej txheem vaj tsev.
Moisturizing khoom
E15 muaj peev xwm moisturizing muaj zog thiab tuaj yeem siv los ua moisturizer hauv cov tshuaj pleev ib ce thiab cov khoom tu tawv nqaij kom cov tawv nqaij moist thiab du. Hauv kev lag luam khoom noj khoom haus, nws tseem tuaj yeem siv los ua cov khoom noj khoom haus kom ntev lub neej ntawm cov khoom noj.
3. Daim ntawv thov teb
Kev lag luam zaub mov
Hauv kev lag luam zaub mov, HPMC E15 feem ntau yog siv los ua cov thickener, stabilizer thiab emulsifier. Nws tuaj yeem siv los tsim cov dej khov nab kuab, jelly, kua ntses thiab cov khoom lag luam pasta, thiab lwm yam, txhawm rau txhim kho saj thiab kev ntxhib los mos ntawm cov zaub mov thiab txuas ntxiv nws lub neej txee.
Kev lag luam kws tshuaj
HPMC E15 yog siv dav hauv kev npaj tshuaj hauv kev lag luam tshuaj, tshwj xeeb tshaj yog cov khoom siv tseem ceeb rau kev tswj-tso thiab cov ntsiav tshuaj tso tawm. Nws tuaj yeem tswj tau qhov tso tawm ntawm cov tshuaj thiab txhim kho kev ruaj ntseg thiab kav ntev ntawm kev siv tshuaj. Tsis tas li ntawd, E15 kuj tseem siv rau hauv kev npaj kho qhov muag, tshuaj pleev xim thiab emulsions, thiab lwm yam, nrog rau biocompatibility zoo thiab kev nyab xeeb.
4. Kev nyab xeeb thiab kev tiv thaiv ib puag ncig
HPMC E15 yog cov tshuaj tsis muaj tshuaj lom thiab tsis ua rau cov cellulose derivative nrog zoo biocompatibility thiab kev nyab xeeb. Nws yog dav siv nyob rau hauv cov khoom noj thiab tshuaj thiab ua tau raws li cov qauv kev nyab xeeb thiab cov kev cai tswj hwm. Tsis tas li ntawd, E15 muaj biodegradability zoo thiab yuav tsis ua phem rau ib puag ncig, uas ua tau raws li cov kev xav tau ntawm lub neej niaj hnub rau cov khoom siv ntsuab thiab ib puag ncig zoo.
Hydroxypropyl methylcellulose E15 tau dhau los ua ib qho tseem ceeb ntxiv hauv ntau qhov kev lag luam vim nws lub cev thiab tshuaj lom neeg tshwj xeeb thiab ntau yam kev siv ua haujlwm. Nws muaj cov thickening zoo heev, stabilizing, zaj duab xis-tsim thiab moisturizing zog thiab yog dav siv nyob rau hauv cov khoom noj, tshuaj, kev tsim kho thiab tshuaj pleev ib ce. Nyob rau tib lub sijhawm, E15 muaj kev nyab xeeb zoo thiab kev tiv thaiv ib puag ncig, thiab yog ib qho khoom siv ntsuab tsis tseem ceeb hauv kev lag luam niaj hnub no.
