Hydroxy Propyl Methyl Cellulose
CAS-Naj Npawb: 9004-65-3
Khoom siv thiab daim ntawv sau npe
Methyl cellulose (MC) & Hydroxypropyl methyl cellulose (HPMC) yog Non-ionic cellulose ether uas tsim los ntawm ntuj high molecular cellulose, los ntawm koob tshuaj tshuaj thiab txheej txheem.
Lawv yog cov xim tsis muaj xim, tsw ntxhiab, cov hmoov tsis dawb, dej-soluble,
Muaj ib qho zoo tuab, ua kom zoo nkauj, ua kom zoo, ua kom zoo, ua kom tsis muaj zog, ua haujlwm, ua haujlwm, ua haujlwm, ua kom tawv, thiab tsis muaj zog.
Yog li, HPMC nws yog dav siv hauv kev tsim kho, xim, hluavtaws, khoom siv, khoom noj khoom haus, luam yeeb, luam yeeb, niaj hnub chemical, petrochemical thiab electronic industries.
Cov khoom lag luam:
1. Siv cov kua dej txias tuaj yeem ua ke thiab tuaj ua cov pobzeb nplaum.
2. Cov tshuaj tua kua hauv cov organic: Cov tshuaj HPMC tuaj yeem ua rau cov kua organic los ua cov tshuaj hydrophobic methoxy, thiab tuaj yeem kho tau dej thiab cov organic tov.
3. Kev ua kom siab ntsev: Nws yog ib qho dej tsis sib tov, nyob hauv dej los ntawm cov ntsev hlau thiab cov organic electrolyte uas ruaj khov.
4. Yam dej num: Dej dej ntawm HPMC muaj kev ua dej, emulsification, kev tiv thaiv colloid thiab thaj chaw ruaj ntseg thaj chaw.
5. Khoom siv hluav taws xob hauv tsev: Cov kua dej HPMC los ua opacity thaum rhuab hauv tej qhov kub, kom txog rau thaum tag nrho cov tshuaj kom haum mus rau hauv ib qho chaw ywj pheej uas tsis tuaj yeem khiav, ces xoob qhov ua kom tsis muaj zog. Nws yog zoo thaum kub kub poob. Qhov kub ntawm lub cev tuaj ntawm lub cev tuaj yeem yog nyob ntawm seb hom tshuaj twg, cov kua tshuaj thiab kev kub ceev.
6. Tshauv qis tsis tshua muaj: Thaum cov khoom siv thermal gelation, zoo txheej txheem nrog dej kub ntxuav ua cov ntoo tshauv qis tsawg.
7. pH stability: Qhov dej ntawm qhov dej ntawm cov dej tsis ruaj ntseg nyob hauv pH 3.0-11.0.
8. Dej khaws: Hydrophilicity ntawm HPMC ua rau nws khaws cov dej ntawm mortar, plaster, xim.
9. Txhim kho duab: Piv rau lwm cov dej soluble polymer, Cov kua dej HPMC muaj viscoelastic tshwj xeeb. HPMC tuaj yeem khaws cov duab ntawm cov khoom siv zom zaws.
10. Lubrication: Ntxiv HPMC yuav txo qhov kev sib txhuam thiab txhim khu lub lubrication ntawm squeezed ceramic thiab MAAs khoom.
11. Kev Ua Yeeb Yam Ua Si: HPMC muaj peev xwm ua tau yooj yim, pob tshab, zoo tswv yim ua yeeb yaj kiab, muaj roj cov khoom uas tsis haum.
Lub cev nqaij daim tawv
1. Tshwm sim: Dawb hmoov, tsis muaj xim, tsw, tsis toxic.
2. Qhov loj me me: Tus nqi kwv yees ntawm 100 mesh ntau tshaj 98.5%; Thiab 80 mesh yog 100%.
3. ceev: 0.25-0.70g / cm. Kev nqus tshwj xeeb 1.26-1.31
4. Tshaj tawm kub: 190-200 centigrade.
5. Qhov nro qhov dav hlau: 42-56 dynam / cm hauv 2% tov dej.
6. Kev Kab Ntseg: Siv cov dej thiab cov tshuaj ua kua, cov tshuaj tov dej muaj txheej txheem deg. Siab pob tshab, stability, solubility yoj nrog viscosity, sab viscosity siab solubility.
HPMC muaj thickening, ntsev resistant, stability pH, dej retain, duab stability, zoo nkauj zaj duab xis thiab dav enzyme ua hauj, dispersion, adhesion thiab lwm yam.
