HydroxyPropyyl methylcellulose (HPMC)yog cov tsis-ionic cellulose ether. Vim nws lub cev nqaij daim tawv thiab tshuaj lom neeg thiab cov tshuaj siv ntau yam, nws tau dhau los ua cov khoom siv tsis tau hauv ntau qhov kev lag luam.
1. Cov yam ntxwv ntawm hydroxypropyl methylcelulose
Cov qauv ntawm HPMC yog tau los ntawm kev hloov cellulation cellulose. Nws muaj cov dej ua kom zoo thiab ruaj khov, thiab muaj ntau yam khoom ua tau zoo:
Zoo heev cov dej solubility duas: txhawj xeeb ® Nws cov solubility yuav tsis hloov pauv qhov tseem ceeb vim tias kev hloov pauv ntawm PHIC tus nqi, thiab nws yog qhov tsim nyog rau kev siv hauv cov chaw sib txawv.
Thickening thiab tsev muaj peev xwm ua lub peev xwm: HPMC muaj cov nyhuv tuab tuab thiab muaj zog txhim kho lub viscosity thiab rheological cov khoom ntawm cov khoom. Cov yeeb yam no yog qhov tseem ceeb tshwj xeeb hauv cov ntaub ntawv hauv tsev, txheej thiab cov tshuaj pleev ib ce.
Zaj duab xis-ua thiab dej khaws cia: HPMC tuaj yeem tsim cov yeeb yaj kiab tsis zoo thiab muab kev tiv thaiv kev tiv thaiv zoo heev. Nyob rau tib lub sijhawm, nws cov cuab yeej siv dej yuav pab txuas ntxiv siv lub sijhawm ntawm cov khoom lag luam thiab txhim kho cov nyhuv siv.
Muaj zog ruaj khov: HPMC yog lub teeb-resistant, kub-resistant, thiab tswj hwm kom nws ua haujlwm ruaj khov nyob rau hauv ntau cov haujlwm tshwj xeeb.
Tsis-lom thiab ib puag ncig tus phooj ywg: HPMC yog tsis muaj tshuaj lom rau tib neeg lub cev thiab tuaj yeem yog cov kev tiv thaiv ntawm lub neej niaj puag ncig thiab kev nyab xeeb.
2. Cov chaw ntawm cov chaw thov
HPMC tau dav siv nyob rau hauv ntau qhov kev lag luam vim tias nws cov versatility, feem ntau yog suav nrog cov chaw hauv qab no:
Kev tsim kho teb: HPMC yog qhov tseem ceeb ntxiv hauv cov ntaub ntawv tsim kho, xws li kev ua haujlwm dej, kev txhim kho los tiv thaiv kev ua tau zoo, thiab txhim kho tsev neeg lub zog thiab ruaj khov.
Kws Tshuaj thiab Kev Lag Luam Khoom Noj: Hauv lub chaw muag tshuaj, HPMC yog siv los ua phau ntawv, cov khoom siv hluav taws xob thiab tshuaj ntsiav tshuaj rau cov ntsiav tshuaj; Hauv kev lag luam khoom noj khoom haus, nws yog siv los ua cov tuab, stabilizer thiab emulsifier los pab txhim kho kev ntxhib los mos thiab txuag khoom noj.
Kev lag luam txhua hnub: HPMC feem ntau siv hauv cov tshuaj pleev ib ce thiab cov khoom siv kho mob rau lub ntsej muag thiab tshuaj pleev ntsej muag thiab txhim kho cov khoom lag luam.
Cov xim pleev xim rau cov xim tha xim: HPMC yog siv nyob rau hauv cov dej txheej txheem kom txhim kho nws cov khoom lag luam leveling thiab sagging yam khoom, thaum txhim kho cov nplaum thiab ruaj khov ntawm txheej.
Ua liaj / teb thiab lwm cov liaj teb: hauv kev ua liaj ua teb Nws tseem siv hauv kev lag luam ceramic thiab cov khoom siv hluav taws xob, feem ntau yog txhim kho cov rheology thiab kev ruaj khov hauv kev siv thev naus laus zis.
3. Kev Lag Luam Xav Tau Tsav
Txoj kev thov thoob plaws HPMC tsis yog vim nws cov kev ua tau zoo, tab sis kuj yog vim muaj kev txhawb nqa ntawm cov kev xav tau niaj hnub no:
Kev loj hlob sai ntawm kev tsim kho kev tsim kho: Cov txheej txheem thoob ntiaj teb tau tsav qhov kev thov hauv tsev, thiab cov versatility ntawm HPMC hauv cov ntaub ntawv tsim vaj tsev ua rau nws muaj cov khoom lag luam me me.
Kev paub txog kev noj qab haus huv thiab ib puag ncig muaj ntau zuj zus: cov neeg tau txais kev pab tau nce ntxiv rau kev nyab xeeb thiab kev tiv thaiv ib puag ncig tshuaj, khoom noj thiab tshuaj lom cov khoom noj txhua hnub. HPMC yog tus tsim nyog los ntawm kev lag luam vim tias nws tsis muaj tshuaj lom, tsis muaj teeb meem thiab cov neeg tsis muaj teeb meem.
Kev siv thev naus laus zis thiab cov khoom lag luam siab: hadnincel ®
Qhov yuav tsum tau hloov cov ntaub ntawv ib txwm muaj: hauv ntau daim ntawv thov, HPMC tau maj hloov cov ntaub ntawv thiab ua kev lag luam thiab kev xaiv zoo.
HydroxyPropyyl MethylcelluloseTau dhau los ua cov khoom tseem ceeb hauv ntau qhov kev lag luam vim nws kev ua tau zoo, muaj ntau yam kev siv thiab siab nrog kev thov kev lag luam. Nrog rau kev txhim kho ntxiv ntawm kev ua haujlwm thoob ntiaj teb thiab kev paub txog HPMC yuav txuas ntxiv mus ntxiv, thiab nws cov kev lag luam yog qhov dav heev.
