Siv cov qib HEMC

Siv cov qib HEMCHydroxyethylMEthylCtso tsegyog paub li methyl hydrotyl cellulose (MHEC), nwsyog dawb los yog txov hmoov dawb, tsw ntxhiab tsw thiab tsis muaj qab, solubleNyob rau hauv ob qho dej kub thiab dej txias. ARC YUAV TSUM TAUSiv raws li cov cement, gypsum, txiv qaub gelling tus neeg sawv cev, dej tswj hwm tus neeg saib xyuas, yog ib qho zoo nkauj admixture rau hmoov nplej tsev.

ALias: Hydroxyethy Methyl Cellulose; Hydroxyethyl methyl cellulose; hydroxsymethyl ntawm ethyl cellulose; 2-Hydroxyethyl Methanthyl ether cellulose, MethylhydroxyLCellCellulose; Cellulose; 2-hydroxyethyl methyl ether; HEMC;

Hydroymethyllethylecellulose; Hydroxyethyl methyl cellulose; Hydroxymethyl Ethyl cellulose.

Qhia Npe Npe: 9032-42-2

Molecular qauv:

Khoom nta:

1. Pom: HEMC yog dawb lossis yuav luag cov hmoov dawb; Odorless thiab tasteless.

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

3. Ph tus nqi ruaj khov: Lub viscosity hloov tsawg hauv thaj tsam ntawm thaj tsam ntawm 2-12, thiab viscosity yog degraded dhau qhov ntau no.

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

5. Tsis muaj kev sib nqus lus: 0.27-0.60g / cm3.

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

7

8. Vim tias cov khoom muaj cov pab pawg hydroxyethyl, qhov kub ntawm cov khoom mus txog 60-90 ℃. Tsis tas li ntawd, hydroxyethyl pab pawg muaj cov khoom siv hydrophilicity, uas tseem ua rau cov khoom lag luam bonded zoo. Tshwj xeeb tshaj yog nyob rau lub caij ntuj sov thiab kub siab nyob rau lub caij ntuj sov, Hemc muaj ntau dua cov viscosity, thiab cov dej tswjfwm tsis pub tsawg dua 85%.

Cov khoom lag luam qib

Tseem ceeb

Raws li tus neeg saib xyuas saum toj kawg nkaus, Hydroxyethy cellulose hemc muaj cov yam ntxwv hauv qab no ntxiv, ua yeeb yaj kiab, dej-khaws cia thiab muab cov tshuaj tiv thaiv kab mob:

(1) Hydroxyethyl Metyl Metyl cellulose hemc yog soluble hauv dej kub lossis dej txias, uas yog, tsis-thermal gelation;

(2) Hydroxyethyl Methyl Cellulose hemc tuaj yeem ua rau muaj lwm yam dej-soluble polymers, thiab yog cov ntsev zoo heev rau cov kev daws teeb meem electrolyte elects;

(3) HEMC muaj cov dej muaj zog khaws cia dua li methyl cellulose, thiab nws mildew tsis muaj zog tshaj li ntawm hydroxyethyl cellulose.

Txoj Kev Txhim Kho Txoj Kev

(1) Ntxiv ib qho nyiaj ntawm cov dej huv rau lub thawv ntim;

(2) Ntxiv hydroxyethyl methyl cellulose hemc nyob rau hauv qis-nrawm brirring, thiab do kom txog thaum txhua tus hydrothethy cellulose yog tusyees yaj;

(3) Hauv kev pom ntawm peb cov ntaub ntawv xeem cov ntaub ntawv, nws yog qhov pom zoo kom ntxiv nws tom qab lub polsteion ntxiv (piv txwv li hydroxyethyl methyl celluloseTus tseem ceebyog ua ntej sib xyaw nrog ethylene glycol lossis propylene glycol).

Usmuaj hnub nyoog

Hauv kev muajlub tsevKhoom siv,Siv cov qib HEMCyog haum rauPobzeb nplaum, Maas Yas, Mixed sib xyaw ua ke, kev siv tus kheej, gypsum plaster,Cov xim av looj, cov khoom siv tsim khoom, cov khoom lag luam uas muaj zog, thiab cov khoom siv tshuaj tiv thaiv kev tiv thaiv, thiab cov khoom siv ntxuav cov roj ntsha , Npaj Matrix-hom kev npaj-tso tawm, thiab kuj tseem siv tau los ua cov khoom noj khoom haus stabilizers hauv cov zaub mov, thiab lwm yam.

Pua yeeb yam Thiab Cia

(1) ntim rau hauv cov ntawv yas composite polyethylene hnab lossis ntawv hnab, 25kg / hnab;

(2) Ua kom cov pa ntws hauv qhov chaw cia, kom tsis txhob muaj hnub ci, thiab tshem tawm ntawm cov chaw tua 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 muab ntim thiab khaws cia, thiab muaj kev tiv thaiv los ntawm noo noo.
