Detergent Thickener Hydroxypropyl Methyl Cellulose Ether HPMC
Siab viscosity HPMC hydroxypropyl methyl cellulose Thickener Rau putty hmoov:
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 nyob rau hauv acetone nyob ntawm seb lub 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 colloidal daws.
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 yuav pos huab los yog tsim 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, qhov 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 lwm yam ntxwv, piv txwv li, thickening khoom, pH stability, tuav dej, zoo heev film-forming khoom, zoo disperse thiab adhesion muaj peev xwm.

Youngcel cov khoom lag luam suav nrog txhua yam khoom ua kua xws li cov tshuaj ntxuav hauv pem teb, cov tshuaj ntxuav tais diav thiab cov khoom ntxuav tais diav nrog pH ntawm 6- 8
HluasQhov nol tuaj yeem siv los ua cov thickener los kho cov rheology ntawm cov kua detergents, kho kom haum raws li qhov xav tau thiab qhov zoo sib xws.
HluasQhov nol enables viscous formulas thiab gel cleaners yuav pab tau ntxiv thiab zoo dua, vim HluasQhov nol yuav cia cov tshuaj ntxuav gel tso rau ntawm qhov chaw thiab ua haujlwm rau lub sijhawm ntev, yog li kev ntxuav tau zoo dua.
