Hydroxypropyl methylcellulose (HPMC) yog non-ionic cellulose ether nrog ntau lub zog thiab ntau yam kev siv.
1. Cov khoom siv hauv tsev
Hauv kev tsim kho kev lag luam, HPMC tau siv dav hauv cov khoom lag luam xws li cement mortar, gypsum-based cov ntaub ntawv, putty hmoov thiab pobzeb nplaum. Nws lub luag haujlwm tseem ceeb suav nrog:
Kev tuav dej: HPMC tuaj yeem txhim kho cov dej tuav ntawm mortar thiab tiv thaiv dej los ntawm evaporating sai heev, yog li txhim kho kev tsim kho thiab kho cov nyhuv.
Thickening thiab lubrication: Nws tuaj yeem ua kom cov viscosity thiab fluidity ntawm cov mortar, ua rau kev tsim kho smoother thiab txo cov hnav cov cuab yeej siv.
Anti-cracking: Los ntawm kev txhim kho cov dej tuav thiab adhesion ntawm mortar, HPMC tuaj yeem tiv thaiv mortar thiab plaster los ntawm kev tawg thaum lub sijhawm kho.
2. Txheej thiab xim
Hauv kev lag luam xim thiab coatings, HPMC yog siv los ua cov thickener, emulsifier thiab stabilizer. Nws cov haujlwm muaj xws li:
Thickening: Ua kom cov viscosity ntawm cov xim, tiv thaiv sagging, thiab txhim kho cov uniformity ntawm txheej.
Kev ruaj ntseg: Pab kom muaj kev sib cais ntawm cov xim thiab cov fillers, tiv thaiv kev daws teeb meem thiab delamination.
Anti-sag khoom: Txhim kho cov txheej txheem ntawm cov xim thiab tiv thaiv sagging thiab poob.
3. Pharmaceuticals thiab zaub mov
Hauv kev lag luam tshuaj thiab khoom noj khoom haus, HPMC feem ntau yog siv rau hauv cov ntsiav tshuaj, tshuaj ntsiav thiab cov khoom noj ntxiv. Nws cov haujlwm yog raws li nram no:
Cov ntsiav tshuaj txheej: Raws li cov ntsiav tshuaj txheej khoom, HPMC tuaj yeem tswj cov tshuaj tso tawm thiab tiv thaiv cov tshuaj los ntawm ya raws thiab oxygen.
Capsule plhaub: HPMC yog cov khoom tseem ceeb ntawm cov neeg tsis noj nqaij cov tshuaj ntsiav, haum rau cov neeg tsis noj nqaij thiab cov neeg tsis haum rau tsiaj los ntawm cov tshuaj ntsiav.
Thickeners thiab emulsifiers: Hauv cov khoom noj, HPMC yog siv los ua cov thickener, emulsifier thiab stabilizer los txhim kho cov kev ntxhib los mos thiab saj ntawm cov zaub mov.
4. Tshuaj pleev ib ce
Hauv kev lag luam tshuaj pleev ib ce, HPMC yog siv rau hauv cov khoom xws li tshuaj pleev, cream, tshuaj zawv plaub hau thiab tshuaj txhuam hniav. Nws lub luag haujlwm tseem ceeb suav nrog:
Thickening: Muab qhov zoo tshaj plaws viscosity thiab sib xws, ua cov khoom siv yooj yim rau kev thov thiab nqus.
Zaj duab xis-forming zog: Tsim cov pob tshab tiv thaiv zaj duab xis los txhim kho daim tawv nqaij moisturizing nyhuv.
Emulsification thiab Stabilization: Pab emulsify thiab stabilize dej-roj sib tov los tiv thaiv stratification.
5. Lwm yam kev siv
HPMC kuj tseem siv tau rau ntau qhov chaw xws li:
Printing ink: Ua cov thickener thiab stabilizer los txhim kho kev luam ntawv zoo.
Kev Ua Liaj Ua Teb: Siv los ua cov ntawv khi rau cov noob txheej thiab tshuaj tua kab hauv kev ua liaj ua teb txhawm rau txhim kho kev ua tau zoo thiab cov noob germination tus nqi.
Textile: Siv hauv textile printing thiab dyeing txheej txheem los txhim kho kev luam ntawv zoo thiab xim ceev.
6. Cov yam ntxwv thiab cov txiaj ntsig
HPMC ua lub luag haujlwm tseem ceeb hauv ntau qhov kev lag luam vim nws lub cev thiab tshuaj lom neeg tshwj xeeb. Nws cov yam ntxwv tseem ceeb muaj xws li:
Dej solubility: HPMC tuaj yeem yaj sai sai hauv dej txias lossis dej kub los tsim cov kua dej ntshiab colloidal.
Biocompatibility thiab kev nyab xeeb: HPMC yog non-toxic thiab harmless, muaj biocompatibility zoo, thiab yog dav siv nyob rau hauv cov zaub mov thiab kws tshuaj.
Stability: Resistant rau cov kua qaub, alkalis thiab ntsev, muaj kev ruaj ntseg zoo thiab tuaj yeem tswj hwm nws txoj haujlwm hauv ntau qhov chaw.
Hydroxypropyl methylcellulose yog dav siv nyob rau hauv kev tsim kho, txheej, tshuaj, khoom noj khoom haus, tshuaj pleev ib ce thiab lwm yam lag luam vim nws versatility thiab kev ua tau zoo. Nws cov haujlwm ntawm thickening, dej tuav, emulsification thiab stabilization ua rau nws yog ib qho tseem ceeb muaj nyob rau hauv ntau yam khoom, ua ib qho tseem ceeb pab rau kev txhim kho cov khoom ua tau zoo thiab cov neeg siv kev.
