Txhim kho cov ntaub ntawv hauv tsev - Hydroxypropyl methylcellulose

HydroxyPropyyl methylcellose (HPMC luv luv ether, thiab yog siv tshuaj lom neeg txhua hnub, thiab yog siv tshuaj lom neeg txhua hnub, thickening, Emulsify, ruaj khov thiab cov nplaum, thiab lwm yam, thiab muaj qhov sib txawv loj hauv kev ua lag luam hauv tsev.

HydroxyPropyyl methylulose yog dav siv nyob rau hauv kev tsim kho kev tsim kho nyob rau hauv kev tsim kho cov neeg sawv cev, there, thiab lwm yam, thiab nws tau dhau los ua cov khoom lag luam hnub qub uas muaj kev nyiam ua kom zoo nkauj txij li thaum nws tau tsim tawm ntawm kab.

Hydroxypropyloosylcelleculose

Hmong Full Lub Npe: HydroxyPropyyl Methylropy Cellulose English LandedTomiation: HPMC

Vim tias HPMC muaj cov khoom zoo heev xws li thickening, zaj duab xis, noo noo siv, cov khoom siv hluav taws xob, textiles, textiles, textiles, textiles, textiles, textiles, textiles, textiles, cov ntawv nyeem, tshuaj, Kev siv txhua hnub, cov khoom siv hluav taws xob thiab cov noob ua liaj ua teb thiab lwm lub chaw haujlwm.

Tsev cov ntaub ntawv

Hauv cov ntaub ntawv hauv tsev, HPMC lossis MC feem ntau ntxiv rau cov cement, tshuaj khib, thiab tshuaj khib kom txhim kho kev tsim kho thiab dej khaws cia.

Yuav siv tau raws li:

1). Nplaum thiab caulking tus neeg sawv cev rau gypsum-raws li cov nplaum nplaum;

2). Kev sib raug zoo ntawm cov cement-raws cov cib, cov vuas thiab lub hauv paus;

3). Plasterboard-based stcco;

4). Cement-raws cov txheej txheem plaster;

5). Hauv cov qauv ntawm cov xim pleev xim thiab pleev xim kom tsis txhob pleev xim.

Nplaum rau cov vuas luaj ceramic

HPMC 15.3 Yam

Perlite 19.1 ntu

Cov rog nyob ntawm cov rog thiab ua kom loj hlob ntawm cov tebchaw 2.0 ntu

Av nplaum 95.4 Ntu

Silica Seasoning (22μ) 420 ntu

450.4 ntu ntawm dej

Siv hauv Maas ua ke nrog inorganic cib, vuas, pob zeb lossis xis mas:

HPMC (dispersion ncua sij hawm 1.3) 0.3 ntu

Cattelan xis mas 100 qhov chaw

Silica Sand 50 Qhov

50 seem ntawm cov dej

Siv raws li lub siab khov kho cement tsev khoom ntxiv:

Cattelan xis mas 100 qhov chaw

Asbestos 5 ntu

Kev haus dej cawv polyvinyl kho 1 ntu

Calcium silicate 15 ntu

Av nplaum 0.5 Qhov

32 seem ntawm dej

HPMC 0.8 Qhov Chaw

Xim Kev Lag Luam

In the paint industry, HPMC is mostly used in latex paint and water-soluble resin paint components as a film-forming agent, thickener, emulsifier and stabilizer.

Kev Ncua Ntawv Polymerization Ntawm Pvc

Lub teb nrog kev noj ntau tshaj plaws ntawm HPMC cov khoom lag luam hauv kuv lub tebchaws yog Kev Kawm Ntawv Polymerization ntawm Vinyl Chloride. Nyob rau hauv kev ncua kev kawm polymerization ntawm vinyl chloride, qhov system dispersion ncaj qha cuam tshuam qhov zoo ntawm cov khoom siv pvc resin thiab nws cov khoom siv thiab cov khoom lag luam; Nws tuaj yeem txhim kho lub thermal stability ntawm lub cob thiab tswj lub particle loj faib (uas yog, kho lub ntom ntom ntawm PVC). Tus nqi HPMC cov txhab nyiaj rau 0.025% ~ 0.03 ntawm lub pvc tso zis%.

Lub pvc resin npaj los ntawm cov zoo HPMC, ntxiv rau kom ntseeg tau tias kev ua tau zoo lub teb chaws, kuj muaj cov yam ntxwv zoo, zoo heev melt rheological tus cwj pwm.

Lwm yam kev lag luam

Lwm cov kev lag luam feem ntau suav nrog cov tshuaj pleev ib ce, cov tshuaj tsuag roj, tshuaj ntsuam xyuas, tsev neeg ceramics thiab lwm yam lag luam.

Dej Soluble

HPMC yog ib qho ntawm cov dej-soluble polymers, thiab nws cov dej solubility yog cuam tshuam nrog cov ntsiab lus ntawm methoxyl pab pawg. Thaum cov ntsiab lus ntawm mexoxyl pab pawg yog tsawg, nws tuaj yeem yaj nyob rau hauv muaj zog alkali thiab tsis muaj thermodynamic gelation point. Nrog kev nce methoxyl cov ntsiab lus, nws yog qhov rhiab rau dej o thiab soluble hauv dilute alkali thiab qaug zog alkali. Thaum cov ntsiab lus methoxyl yog> 38C, nws tuaj yeem yaj nyob hauv dej, thiab tuaj yeem ua kom yaj nyob rau hauv halogenated hydrocarbons. Yog tias muaj cov kua qaub nyob rau HPMC, HPMC yuav nrawm dua hauv dej tsis tsim cov tshuaj chelolle insoluble. Qhov no yog feem ntau yog vim yog qhov tseeb tias qee lub sijhawm acid muaj pawg acid muaj pawg hauv Ortho txoj hauj lwm ntawm cov dispersed glycogen.
