Qib kev tsim kho HEMC

Qib kev tsim kho HEMCHydroxyethylMethylCellulosehu ua Methyl Hydroxyethyl Cellulose (MHEC), nwsyog hmoov dawb los yog dawb tawm, tsis muaj ntxhiab thiab tsis qab, yaj tauHauv ob qho dej kub thiab dej txias. Qib kev tsim kho HEMC tuaj yeem ua tauSiv ua cement, gypsum, lime gelling agent, water retention agent, yog ib qho admixture zoo heev rau cov hmoov khoom siv hauv tsev.

Acov tshuaj sib xyaw: hydroxyethyl methyl cellulose; hydroxyethyl methyl cellulose; hydroxymethyl ethyl cellulose; 2-hydroxyethyl methyl ether cellulose, Methylhydroxyethylcellulose; Cellulose; 2-hydroxyethyl methyl ether; HEMC;

Hydroymethylmethylecellulose; hydroxyethyl methyl cellulose; hydroxymethyl ethyl cellulose.

CAS sau npe: 9032-42-2

Cov Qauv Molecular:

Cov yam ntxwv ntawm cov khoom:

1. Tsos: HEMC yog hmoov dawb los yog yuav luag dawb; tsis muaj ntxhiab thiab tsis qab.

2. Kev yaj: Hom H hauv HEMC tuaj yeem yaj hauv dej qis dua 60 ℃, thiab hom L tsuas yog yaj hauv dej txias xwb. HEMC zoo ib yam li HPMC thiab tsis yaj hauv feem ntau cov kuab tshuaj organic. Tom qab kev kho saum npoo, HEMC tawg hauv dej txias yam tsis muaj kev sib sau ua ke thiab yaj qeeb qeeb, tab sis nws tuaj yeem yaj sai sai los ntawm kev kho nws tus nqi PH rau 8-10.

3. PH tus nqi ruaj khov: Qhov viscosity hloov me ntsis hauv qhov ntau ntawm 2-12, thiab qhov viscosity raug rhuav tshem dhau qhov ntau no.

4. Kev Zoo: tus nqi dhau ntawm 80 mesh yog 100%; tus nqi dhau ntawm 100 mesh yog ≥99.5%.

5. Qhov hnyav tshwj xeeb cuav: 0.27-0.60g / cm3.

6. Qhov kub ntawm qhov lwj yog siab tshaj 200 ℃, thiab nws pib hlawv ntawm 360 ℃.

7. HEMC muaj qhov tuab, kev ruaj khov ntawm kev ncua, kev sib kis, kev sib koom ua ke, kev pwm, kev khaws dej thiab lwm yam ntxwv.

8. Vim tias cov khoom muaj hydroxyethyl pawg, qhov kub ntawm cov khoom gel ncav cuag 60-90 ℃. Tsis tas li ntawd, hydroxyethyl pawg muaj hydrophilicity siab, uas kuj ua rau cov khoom sib txuas zoo. Tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias siab hauv lub caij ntuj sov, HEMC muaj dej khaws cia siab dua li methyl cellulose ntawm tib viscosity, thiab dej khaws cia tus nqi tsis tsawg dua 85%.

Cov Khoom Qib

Qhov Tseem Ceeb

Ua tus neeg sawv cev nto, hydroxyethyl methyl cellulose HEMC muaj cov yam ntxwv hauv qab no ntxiv rau kev ua kom tuab, ncua, sib txuas, emulsifying, zaj duab xis-tsim, tawg, khaws dej thiab muab cov colloids tiv thaiv:

(1) Hydroxyethyl methyl cellulose HEMC yaj tau hauv dej kub lossis dej txias, ua rau nws muaj ntau yam solubility thiab viscosity yam ntxwv, uas yog, tsis yog thermal gelation;

(2) Hydroxyethyl methyl cellulose HEMC tuaj yeem nyob ua ke nrog ntau yam lwm yam polymers uas yaj hauv dej, surfactants, thiab ntsev, thiab yog ib qho thickener zoo heev rau cov kua electrolyte uas muaj concentration siab;

(3) HEMC muaj zog khaws dej ntau dua li methyl cellulose, thiab nws qhov kev ruaj khov viscosity, dispersibility, thiab mildew tsis kam yog muaj zog dua li ntawm hydroxyethyl cellulose.

Txoj kev npaj cov tshuaj

(1) Ntxiv ib qho dej huv uas tau teev tseg rau hauv lub thawv;

(2) Ntxiv hydroxyethyl methyl cellulose HEMC nyob rau hauv qab qhov kev sib xyaw qeeb qeeb, thiab do kom txog thaum tag nrho cov hydroxyethyl methyl cellulose yaj sib npaug;

(3) Vim peb cov ntaub ntawv xeem txog kev siv tshuab, nws raug pom zoo kom ntxiv nws tom qab ntxiv cov polymer emulsion (piv txwv li, hydroxyethyl methyl cellulose)HEMCyog sib xyaw ua ntej nrog ethylene glycol lossis propylene glycol).

Ushnub nyoog

Hauv kev lag luamlub tsevcov ntaub ntawv,qib kev tsim kho HEMCyog tsim raunplaum pobzeb, cement plasters, qhuav sib xyaw mortar, tus kheej leveling, gypsum plaster,Xim latex, cov khoom siv khi rau hauv tsev, lwm yam kev tsim kho, kev khawb roj av, cov khoom siv tu tus kheej, cov neeg ntxuav, thiab lwm yam, feem ntau siv ua cov khoom ua kom tuab, cov neeg sawv cev tiv thaiv, cov nplaum, cov stabilizers, thiab cov neeg sawv cev ncua nws kuj siv tau ua cov gels hydrophilic, cov ntaub ntawv matrix, npaj cov khoom npaj tso tawm matrix-hom, thiab kuj siv tau ua cov stabilizers hauv cov khoom noj, thiab lwm yam. Cov nyhuv.

Pkev them nqi thiab qhov chaw cia khoom

(1) Ntim rau hauv hnab yas polyethylene lossis hnab ntawv, 25KG / hnab;

(2) Khaws cov cua kom ntws hauv qhov chaw cia khoom, tsis txhob cia tshav ntuj ncaj qha, thiab khaws cia deb ntawm cov chaw hluav taws;

(3) Vim tias hydroxyethyl methyl cellulose HEMC yog hygroscopic, nws yuav tsum tsis txhob raug rau huab cua. Cov khoom tsis siv yuav tsum tau kaw thiab khaws cia, thiab tiv thaiv kom tsis txhob muaj dej noo.
