1. Hydroxypropyl methylcellulose yog dab tsi?
Hydroxypropyl methylcellulose (HPMC)yog ib qho tsis muaj tshuaj lom thiab tsis muaj mob uas tsis yog-ionic cellulose ether, dav siv hauv cov khoom siv hauv tsev, khoom noj, tshuaj, tshuaj pleev ib ce thiab lwm yam. Nws muaj kev ua haujlwm ntawm thickening, dej tuav, tsim zaj duab xis, kev sib txuas, lubrication thiab ncua kev kawm ntawv, thiab tuaj yeem yaj hauv dej los tsim cov pob tshab los yog cov kua nplaum.
2. Kev siv thiab kev siv ntawm HPMC
Kev tsim kho teb
HPMC feem ntau siv rau hauv cov khoom siv hauv tsev xws li cement mortar, putty hmoov, pobzeb nplaum, thiab lwm yam.:
Muaj nuj nqi: Txhim kho kev tsim kho, txhim kho kev tuav dej, ncua sij hawm qhib, thiab txhim kho kev sib raug zoo.
Txoj kev siv:
Ntxiv ncaj qha rau cov khoom sib xyaw qhuav, qhov pom zoo yog 0.1% ~ 0.5% ntawm cov cement lossis substrate;
Tom qab tag nrho stirring, ntxiv dej thiab do rau hauv slurry.
Kev lag luam zaub mov
HPMC tuaj yeem siv ua cov thickener, stabilizer thiab emulsifier, thiab feem ntau pom muaj nyob rau hauv cov khoom noj xws li ice cream, jelly, qhob cij, thiab lwm yam.:
Muaj nuj nqi: Txhim kho saj, stabilize lub system, thiab tiv thaiv stratification.
Kev siv:
Dissolve nyob rau hauv dej txias, qhov pom zoo npaum li cas yog kho ntawm 0.2% thiab 2% raws li hom zaub mov;
Cua sov los yog mechanical stirring tuaj yeem ua kom tawg.
Kev lag luam kws tshuaj
HPMC feem ntau yog siv rau hauv tshuaj ntsiav tshuaj txheej, sustained-tso ntsiav tshuaj matrix los yog capsule plhaub:
Muaj nuj nqi: tsim zaj duab xis, ncua kev tso tshuaj, thiab tiv thaiv kev ua yeeb yam.
Kev siv:
Npaj rau hauv ib qho kev daws teeb meem nrog qhov concentration ntawm 1% mus rau 5%;
Txau tusyees rau saum npoo ntawm cov ntsiav tshuaj los ua ib zaj duab xis nyias.
Tshuaj pleev ib ce
HPMCyog siv los ua cov thickener, emulsion stabilizer los yog zaj duab xis-tsim tus neeg sawv cev, feem ntau siv hauv lub ntsej muag lub ntsej muag, tshuaj pleev, thiab lwm yam.:
Function: Txhim kho kev ntxhib los mos thiab txhim khu kev xav ntawm cov khoom.
Kev siv:
Ntxiv rau lub cosmetic matrix nyob rau hauv proportions thiab do tusyees;
Qhov ntau npaum li cas yog feem ntau 0.1% rau 1%, kho raws li cov khoom xav tau.
3. HPMC txoj kev sib cais
Lub solubility ntawm HPMC yog heev cuam tshuam los ntawm dej kub:
Nws yog ib qho yooj yim rau yaj hauv dej txias thiab tuaj yeem tsim ib qho kev daws teeb meem;
Nws yog insoluble nyob rau hauv dej kub, tab sis yuav dispersed thiab tsim ib tug colloid tom qab txias.
Cov kauj ruam tshwj xeeb ntawm kev tshem tawm:
Sprinkle HPMC maj mam rau hauv dej, tsis txhob nchuav ncaj qha los tiv thaiv caking;
Siv lub stirrer kom sib tov sib npaug;
Kho cov tshuaj concentration raws li xav tau.
4. Kev ceev faj rau kev siv HPMC
Kev tswj kev noj tshuaj: Hauv cov xwm txheej sib txawv, qhov ntau npaum li cas cuam tshuam ncaj qha rau kev ua haujlwm thiab yuav tsum tau sim raws li kev xav tau.
Cia tej yam kev mob: Nws yuav tsum tau muab cia rau hauv ib tug txias, qhuav, ventilated qhov chaw kom tsis txhob ya raws thiab kub.
Kev tiv thaiv ib puag ncig: HPMC yog biodegradable thiab tsis ua phem rau ib puag ncig, tab sis nws tseem yuav tsum tau siv raws li tus qauv kom tsis txhob pov tseg.
Kev ntsuam xyuas kev sib raug zoo: Thaum ntxiv rau cov txheej txheem nyuaj (xws li tshuaj pleev ib ce lossis tshuaj), kev sib raug zoo nrog lwm cov khoom xyaw yuav tsum tau sim.
5. Qhov zoo ntawm HPMC
Non-toxic, environmentally friendly, kev nyab xeeb siab;
Versatility, adaptable rau ntau yam ntawm daim ntawv thov yuav tsum tau;
Zoo stability, tuaj yeem khaws kev ua haujlwm ntev.
6. Tej teeb meem thiab kev daws teeb meem
Teeb meem agglomeration: Ua tib zoo saib rau qhov sib ntxiv sib cais thaum siv thiab do tag nrho tib lub sijhawm.
Lub sij hawm tawg ntev: Cov dej kub pretreatment lossis mechanical stirring tuaj yeem siv los ua kom nrawm nrawm.
Kev ua haujlwm tsis zoo: Ua tib zoo saib xyuas qhov chaw cia kom tsis txhob ya raws thiab cua sov.
Los ntawm kev siv HPMC scientific thiab rationally, nws cov yam ntxwv multifunctional tuaj yeem siv tag nrho los muab cov kev daws teeb meem zoo rau ntau yam kev lag luam.
