Cov ntsiab lus yooj yim ntawm Hydroxyether Metthylcellose

Suav Lub Npe: Hydroxyethy Metthylcellose
English Lub Npe: Hymetellose328
Suav Alias: Hydroxyethyl methyl cellulose; Hydroxyethyl methyl cellulose; hydroxsymethyl ntawm ethyl cellulose; 2-Hydroxyethyl Methanthyl ether cellulose
Lus Askiv Aliases: Methylhydredoxyethylcelleculose; Cellulose; 2-hydroxyethyl methyl ether; HEMC; Tyopur Mh [1]
Chemistry: Hydroymethyllethylcellulose; Hydroxyethyllethylcellose; Hydroxymethyletylcellulose.

Molecule: C2h6o2 XCH4O X PEUR 2002 txhais tau hydroxyethyl methylulose li ib nrab o-methylated, ib nrab o-hydroxymethylene cellulose. Cov kev sib txawv yog qhia los ntawm lub meej viscosity tus nqi ntawm 2% w / v a aqueous daws ntawm 20 ° C, thiab chav tsev yog mpa s.
Molecular qhov hnyav: Phour 2002 piav txog hydrothethyl methylulose raws li ib nrab o-methylated, ib nrab o-hydroxymethyleneated cellulose. Cov kev sib txawv yog qhia los ntawm lub meej viscosity tus nqi ntawm 2% w / v a aqueous daws ntawm 20 ° C, thiab chav tsev yog mpa s.

Cov yam ntxwv tseem ceeb ntawm hydroxyethy methylcellulose (hemc) yog:

1. Solubility: soluble hauv dej thiab qee cov kuab tshuaj organic. HEMC tuaj yeem raug ntiab tawm hauv dej txias. Nws lub siab tshaj plaws yog tsuas yog txiav txim siab los ntawm viscosity. Solubility sib txawv nrog viscosity. Qhov qis dua viscosity, muaj ntau dua cov solubility.

2. Ntsev tsis kam: HEMSIC Cellulose muaj kev hais txog kev ua haujlwm, tab sis lawv tsis tshua muaj cov tshuaj electrolytes muaj peev xwm ua rau gelation thiab nag lossis daus.

3. Cov kev ua si saum npoo av: Vim tias cov kev ua haujlwm saum npoo hlau ntawm cov aqueous, nws tuaj yeem siv los ua tus neeg sawv cev sib xyaw, emulsifier thiab dispersant.

4. Thermal Gel: Thaum lub HEMC cov tshuaj aqueous yog rhuab rau ib qho kub, tab sis thaum twg nws rov qab los rau thawj lub xeev, thiab dej nag thiab nag lossis daus. Qhov kub feem ntau yog nyob ntawm lawv cov rojricants, txwv tsis pub muaj AIDS, kev tiv thaiv kev tiv thaiv, emulsifiers, thiab lwm yam.

5. Cov tshuaj tsw qab thiab tsw thiab tsw qab: hemc tau siv dav hauv cov zaub mov thiab tshuaj vim tias nws yuav tsis muaj metabolized thiab muaj ntxhiab tsw thiab tsw qab.

6. Mildew Refillance: HEMC muaj qhov zoo dua mildew tsis kam thiab zoo viscosity stabilabe thaum lub sij hawm ntev cia.

7.

Daim ntawv thov: Hydroxyethy Metherylcellulose tuaj yeem siv los ua tus neeg sawv cev sib xyaw, emulsifier thiab dispersant vim nws cov kev daws teeb meem saum toj. Nws daim ntawv thov piv txwv yog raws li hauv qab no: tus ntawm hydroxyethyl methylcellu ntawm kev ua yeeb yam ntawm cov cement. Hydroxyether methylulose yog qhov tsw, tsis muaj kuab dawb uas tuaj yeem yaj nyob rau hauv dej txias los tsim cov tshuaj pleev pob tshab. Nws muaj cov yam ntxwv ntawm thickening, khi, emulsifying, zaj duab xis, tswj kev ua yeeb yam, tswj kev noo thiab tiv thaiv kev sib deev. Vim tias cov kua txiv aque muaj cov haujlwm saum npoo av, nws tuaj yeem siv los ua tus neeg sawv cev sib xyaw, emulsifier thiab dispersant. Hydroxyether methylenose aqueous kua txiv muaj zoo hydrophilicity thiab yog ib tug neeg siv dej ua haujlwm zoo.
