Factory Detergent Raw Materials Cellulose Kev Lag Luam Tshuaj HPMC cellulose ether Hydroxypropyl methyl cellulose

1) Cov tsos mob: HPMC yog ib qho nonionic cellulose ether, dawb greyish-dawb hmoov los yog granule, tsw thiab tsw, soluble nyob rau hauv

dej txias, glacial acetic acid, ethanol, methanol thiab propylene glycol, me ntsis soluble hauv acetone nyob ntawm qhov degree ntawm

hloov, xyaum insoluble hauv dej kub, ethylene glycol thiab toluene. HPMC yog yaj nyob rau hauv ib tug sib tov ntawm 10% methanol

thiab 90% methylene chloride los tsim cov tshuaj colloidal.
2) Cov kev daws teeb meem ntawm HPMC muaj cov dej num saum npoo av, siab pob tshab, thiab kev ua haujlwm ruaj khov. Thaum rhuab ntawm tej qhov kub thiab txias

Cov tshuaj ua cloudy los yog cov ntaub ntawv flocculent gel. Txawm li cas los xij, cov tshuaj yuav pom tseeb dua tom qab txias. Ntau hom

HPMC muaj qhov sib txawv gelation kub. Lub solubility sib txawv nrog cov viscosity. Qhov qis dua qhov viscosity, ntau dua solubility

nws muaj. Cov hom HPMC sib txawv ntawm qee yam khoom thiab lawv cov solubility hauv dej tsis cuam tshuam los ntawm pH.
3) Qhov ntau thiab tsawg: 100% dhau tus nqi hauv 80 mesh.
4) Pom tseeb ntom: 0.25-0.70 g / mL (feem ntau yog li 0.5 g / mL), tshwj xeeb ceev 1.26-1.31mL.
5) Xim hloov kub: 190-200 ° C; Carbonization kub: 280-300 ° C.
6) Nto nro: 42-56 dyn / cm (2% aqueous tov).
7) Cov ntsiab lus methoxy ntau dua hauv HPMC, qis dua gelation kub, thiab ntau dua solubility hauv dej thiab dej ua haujlwm.
8) HPMC muaj ib co lwm yam ntxwv, piv txwv li, thickening khoom, pH stability, tuav dej, zoo heev film-forming

khoom, zoo disperse thiab adhesion muaj peev xwm.
