HydroxyPropyyl methylulose (HPMC), tseem hu ua HydroxyPropyf methylcelulose ether, yog ib qho kev ua haujlwm ntawm cov neeg uas tsis yog. Nws zoo li yog cov hmoov dawb lossis tawv nqaij dawb thiab yog soluble hauv dej thiab qee cov kuab tshuaj organic. Nws cov kev ua yeeb yam aqueous siab siab ntsws muaj siab thiab cov gelation kub sib txawv nyob ntawm cov metrhoxy pawg cov ntsiab lus.
HPMC yog ib tug tseem ceeb tsis txaus siab nyob rau hauv kev ncua polymerization zus tau tej cov polyvinyl chloride (PVC). Nws txo cov kev cuam tshuam interfacial ntawm monomer thiab dej thiab modulates cov resin part porphology los txhim kho kev ua haujlwm. Nws tuaj yeem hloov cov tsoos dispersants thiab tsim cov tshuab nrog cov dej cawv polyvinyl. HPMC kuj tseem siv nyob rau hauv lub tsev lag luam kev lag luam raws li cov neeg saib xyuas dej rau Caas kev lag luam thiab cov khoom siv hluav taws xob rau cov tshuaj ntsiav tshuaj rau cov ntsiav tshuaj rau cov tshuaj ntsiav rau cov tshuaj ntsiav rau cov ntsiav tshuaj Nws txoj kev qhia txuj ci muaj xws li pawg methoxy cov ntsiab lus ntawm 28-30%, thiab kev sib tham ntawm cov khoom siv viscosoxy, suav nrog cov khoom siv viscosoxy, suav nrog cov khoom lag luam hauv tsev, tshuaj lom neeg thiab txhua hnub.
Cov Khoom Siv Siv
Cov khoom no yog siv los ua cov tuab dua, cov nplaum, zam, cov roj-resistant txheej, muab tub ceev, emulsifier thiab stabilizer nyob rau hauv kev lag luam textile. Nws tseem dav siv nyob rau hauv hluavtaws resins, petrochemicals, ceramics, papermaking, tawv, tshuaj, khoom noj thiab tshuaj pleev xim rau kev lag luam.
Khoom nta
Dej Solubility: HPMC tau txhij tag nrho nyob rau hauv dej txias, sib sau ua ib qho kev daws teeb meem meej. Nws tseem ua kom pom cov kev ua si deg.
Thickening: HPMC tuaj yeem ua kom nce viscosity ntawm kev daws teeb meem, ua nws cov tuab tuab.
Dej khaws cia: HPMC cov khoom pov thawj zoo ua kom muaj dej zoo zoo, tiv thaiv kom qhuav ntxov thiab txhim kho cov ntawv thov kev ua tau zoo.
Zaj duab xis-tsim: HPMC cov foos tawv, hloov tau, thiab pob tshab cov yeeb yaj kiab thiab feem ntau siv nyob rau hauv cov ntsiav tshuaj txheej thiab ntim khoom noj.
Cov kev ua si saum npoo av: HPMC AQUS OQUS pom cov haujlwm saum npoo thiab tuaj yeem ua raws li kev tiv thaiv kev tiv thaiv, emulsion stabilizer, thiab dispersant.
Thermogelation: HPMC AQUous OQUS ON a aqueous ingo gelation thaum rhuab rau ib qho kub thiab rov qab mus rau kev daws thaum txias. Cov cuab yeej no tuaj yeem siv los tswj cov tshuaj tso tawm.
Pho stability: HPMC cov khoom pov thawj zoo nyob rau hauv qee cov xov xwm (piv txwv li, 3.0-11.0), thiab cov kua aqueous yog tsis muaj kev cuam tshuam ntawm PH.
Qhov Zoo
HPMC muaj dej zoo heev, thickening, kev ncua, khi, zaj duab xis-sib sau, thiab cov khoom ua si saum npoo av.
