Detergent Thickener Hydroxypropyl Methyl Cellulose Ether HPMC
Siab viscosityHPMCHydroxypropyl methyl cellulose yog sivThickenerRau putty hmoov:
1) Zoo:HPMCyog ib tug nonionic cellulose ether, dawb greyish-dawb hmoov los yog granule, tsw thiab flavorless, soluble nyob rau hauv dej txias, glacial acetic acid, ethanol, methanol thiab propylene glycol, me ntsis soluble nyob rau hauv acetone nyob rau hauv lub degree ntawm kev hloov, xyaum insoluble nyob rau 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 ua 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 solubility ntau dua 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 meej ntom ntom: 0.25-0.70 g / mL (feem ntau yog li 0.5 g / mL), tshwj xeeb ntom ntom 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 siab dua solubility hauv dej thiab ntog dej.
8) HPMC muaj qee qhov lwm yam ntxwv, piv txwv li, cov khoom ua kom tuab, pH ruaj khov, tuav dej, zoo heev cov cuab yeej tsim, zoo disperse thiab adhesion muaj peev xwm.

7) Cov ntsiab lus methoxy ntau dua hauv HPMC, qis dua gelation kub, thiab siab dua solubility hauv dej thiab ntog dej.
8) HPMC muaj qee qhov lwm yam ntxwv, piv txwv li, cov khoom ua kom tuab, pH ruaj khov, tuav dej, zoo heev cov cuab yeej tsim, 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 ntawm6- 8
Hluasceltuaj 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.
Hluascel enables viscous formulas thiab gel cleaners yuav pab tau ntxiv thiab zoo dua, vimHluascelyuav cia cov tshuaj ntxuav gel tso rau ntawm qhov chaw thiab ua haujlwm rau lub sijhawm ntev, yog li kev ntxuav tau zoo dua.
