Kev tsim kho qib HEMC

Kev tsim kho qib HEMC Hydroxyethyl Methyl Cellulose yog hu ua Methyl Hydroxyethyl Cellulose (MHEC), nws yog cov hmoov dawb los yog dawb dawb, tsis muaj ntxhiab thiab tsis qab, soluble hauv dej kub thiab dej txias. Kev tsim kho qib HEMC tuaj yeem siv los ua cov cement, gypsum, txiv qaub gelling tus neeg saib xyuas, tus neeg saib xyuas dej, yog ib qho zoo heev admixture rau hmoov tsev cov ntaub ntawv.

Lub npe: hydroxyethyl methyl cellulose; hydroxyethyl methyl cellulose; hydroxymethyl ethyl cellulose; 2-hydroxyethyl methyl ether cellulose, Methylhydroxyethylcellulose; Cellulose; 2-hydroxyethyl methyl ether; HEMC;

Hydroymethylmethylcellulose; hydroxyethyl methyl cellulose; hydroxymethyl ethyl cellulose.

CAS Nr .: 9032-42-2

Molecular Structure:

Khoom nta:

1. Cov tsos mob: HEMC yog dawb los yog yuav luag dawb hmoov; tsw thiab tasteless.

2. Solubility: Hom H hauv HEMC tuaj yeem yaj hauv dej hauv qab 60 ℃, thiab L hom tsuas tuaj yeem yaj hauv dej txias. HEMC yog tib yam li HPMC thiab yog insoluble nyob rau hauv feem ntau cov organic solvents. Tom qab kev kho deg, HEMC disperses nyob rau hauv dej txias yam tsis muaj agglomeration thiab dissolves maj mam, tab sis nws yuav sai sai yaj los ntawm kev kho nws tus nqi PH rau 8-10.

3. PH tus nqi ruaj ntseg: Lub viscosity hloov me ntsis nyob rau hauv thaj tsam ntawm 2-12, thiab viscosity yog degraded dhau qhov no.

4. Fineness: tus nqi dhau ntawm 80 mesh yog 100%; Tus nqi dhau ntawm 100 mesh yog ≥99.5%.

5. Tsis tseeb lub ntiajteb txawj nqus: 0.27-0.60g/cm3.

6. Lub decomposition kub yog siab tshaj 200 ℃, thiab nws pib hlawv ntawm 360 ℃.

7. HEMC muaj cov thickening tseem ceeb, ncua kev ruaj ntseg, dispersibility, cohesiveness, moldability, dej tuav thiab lwm yam ntxwv.

8. Vim tias cov khoom muaj cov pab pawg hydroxyethyl, gel kub ntawm cov khoom nce mus txog 60-90 ℃. Tsis tas li ntawd, pawg hydroxyethyl muaj hydrophilicity siab, uas kuj ua rau cov khoom sib txuas zoo. Tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab kub kev tsim kho nyob rau hauv lub caij ntuj sov, HEMC muaj dej tuav ntau dua methyl cellulose ntawm tib viscosity, thiab cov dej tuav tus nqi tsis tsawg tshaj li 85%.

Qhov tseem ceeb

Raws li tus neeg sawv cev saum npoo av, hydroxyethyl methyl cellulose HEMC muaj cov yam ntxwv hauv qab no ntxiv rau cov thickening, suspending, bonding, emulsifying, film-forming, dispersing, water-retaining and provide protective colloids:

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

(2) Hydroxyethyl methyl cellulose HEMC tuaj yeem ua ke nrog ntau yam ntawm lwm cov dej-soluble polymers, surfactants, thiab ntsev, thiab yog ib qho zoo heev thickener rau high-concentration electrolyte daws;

(3) HEMC muaj zog tuav dej ntau dua li methyl cellulose, thiab nws cov viscosity stability, dispersibility, thiab mildew kuj muaj zog dua li ntawm hydroxyethyl cellulose.

Txoj kev npaj daws teeb meem

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

(2) Ntxiv hydroxyethyl methyl cellulose HEMC nyob rau hauv qis-ceev stirring, thiab do kom txog thaum tag nrho cov hydroxyethyl methyl cellulose yog tusyees yaj;

(3) Raws li peb cov ntaub ntawv ntsuam xyuas, nws raug pom zoo kom ntxiv nws tom qab cov polymer emulsion ntxiv (piv txwv li, hydroxyethyl methyl cellulose HEMC yog pre-mixed nrog ethylene glycol lossis propylene glycol).

Ushnub nyoog

Hauv cov khoom siv hauv tsev, kev tsim kho qib HEMC yog tsim rau cov pobzeb nplaum, cement plasters, qhuav sib xyaw mortar, tus kheej leveling, gypsum plaster, latex xim, cov khoom siv hauv tsev, lwm yam kev tsim kho, oilfield drilling, khoom tu tus kheej, tshuaj ntxuav, thiab lwm yam. , feem ntau yog siv los ua thickeners, tiv thaiv tus neeg sawv cev, nplaum, stabilizers, thiab suspending agents nws kuj siv tau raws li hydrophilic gels, matrix cov ntaub ntawv, npaj matrix-hom sustained-tso npaj, thiab kuj yuav siv tau raws li stabilizers nyob rau hauv cov khoom noj, thiab lwm yam. .

Packaging thiab khaws cia

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

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

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