Product Description:
Hydroxypropyl Methylcellulose (HPMC) yog cov hmoov dawb uas tsis muaj ntxhiab, tsis muaj tshuaj lom. Tom qab tag nrho yaj nyob rau hauv dej, nws yuav tsim ib tug pob tshab viscous tov. Nws yog ib qho uas tsis yog-ionic cellulose ether ua los ntawm tej yam ntuj tso polymer cov ntaub ntawv los ntawm ib tug series ntawm tshuaj ua. Nws muaj cov yam ntxwv ntawm thickening, adhesion, dispersion, emulsification, zaj duab xis tsim, ncua kev kawm ntawv, adsorption, gelation, deg kev ua si, tuav ntawm noo noo thiab tiv thaiv colloids.
Daim ntawv thov:
Dej solubility thiab thickening peev xwm: nws muaj peev xwm soluble nyob rau hauv dej txias, thiab tsim ib tug pob tshab kua.
Dissolution nyob rau hauv cov kuab tshuaj organic: Vim nws muaj ib tug npaum li cas ntawm hydrophobic methoxy pawg, cov khoom no yuav yaj nyob rau hauv ib co organic solvents.
PH tus nqi ruaj ntseg: Lub viscosity ntawm HPMC cov tshuaj aqueous yog qhov ruaj khov nyob rau hauv thaj tsam ntawm PH tus nqi 3.0-11.0.
Surface Activity: HPMC aqueous solution muaj cov dej num saum npoo av. Nws muaj emulsifying nyhuv, tiv thaiv colloid muaj peev xwm thiab txheeb ze stability.
Thermal gelation: Thaum rhuab saum ib qho kub, cov kua dej ntawm HPMC tuaj yeem ua opaque, tsim los nag, thiab poob viscosity. Txawm li cas los xij, nws maj mam hloov mus rau qhov kev daws teeb meem qub tom qab txias.
Cov ntsiab lus tsis tshua muaj tshauv: HPMC tsis yog-ionic, nws tuaj yeem ntxuav nrog dej kub thaum lub sijhawm npaj thiab ua kom zoo zoo, yog li nws cov hmoov tshauv tsawg heev.
Ntsev tsis kam: Txij li cov khoom no yog non-ionic thiab non-polymeric electrolyte, nws yog ib qho ruaj khov nyob rau hauv aqueous daws ntawm hlau ntsev los yog organic electrolytes.
Cov nyhuv tuav dej: Vim tias HPMC yog hydrophilic thiab nws cov kua dej muaj kuab heev. Nws tuaj yeem muab ntxiv rau hauv mortar, gypsum, xim, thiab lwm yam kom tswj tau cov dej siab hauv cov khoom.
Mildew tsis kam: Nws muaj cov kab mob mildew kuj zoo, thiab muaj viscosity ruaj khov thaum lub sij hawm ntev cia.
Lubricity: Ntxiv HPMC tuaj yeem txo qhov sib txhuam coefficient thiab txhim kho lubricity ntawm extruded ceramic khoom thiab cov khoom cement.
Cov cuab yeej ua yeeb yaj kiab: Nws tuaj yeem tsim muaj zog, hloov tau, pob tshab flakes nrog cov roj zoo thiab ester tsis kam.
Hauv kev tsim cov ntaub ntawv, HPMC cellulose tuaj yeem siv los ua cov dej tuav thiab rov qab rau cov cement slurry los ua cov tshuaj khib nyiab.
Raws li cov nplaum nplaum, kev siv HPMC hauv plasters, gypsum, putty hmoov lossis lwm yam khoom siv hauv tsev tuaj yeem txhim kho lawv txoj kev sib kis thiab ua kom lawv lub sijhawm ua haujlwm ntev.
Nws cov dej tuav tuaj yeem tiv thaiv cov tshuaj txhuam los ntawm kev tawg sai sai tom qab txheej, thiab tuaj yeem txhim kho lub zog ntawm txheej tom qab hardening.
Tsis tas li ntawd, HPMC tshuaj kuj tseem siv tau los ua ib qho kev ua kom zoo rau cov pobzeb, marble, thiab yas kho kom zoo nkauj hauv kev tsim kho kev lag luam.
Tsis tas li ntawd, HPMC hmoov yog siv los ua cov thickener, stabilizer, emulsifier, excipient, thiab dej tuav tus neeg sawv cev hauv kev tsim khoom ntawm lwm yam kev lag luam, xws li petrochemicals, coatings, cov ntaub ntawv hauv tsev, cov xim tshem tawm, cov tshuaj ua liaj ua teb, inks, textile printing thiab dyeing, ceramics, papermaking, tshuaj pleev ib ce, thiab lwm yam.
Pob: 25 kgs / hnab los yog raws li koj thov.
Cia: Khaws ntawm qhov chaw muaj cua, qhuav.
Cov txheej txheem ua tiav: International Standard.
