Cov khoom siv thickening (hydroxyethyl cellulose)

Hydroxyethyl cellulose (HEC) yog xim daj lossis lub teeb tsis zoo, cov tshuaj tsw qab, uas tau npaj los ntawm kev tawm tsam ntawm lub ntsej muag ntawm cov tshuaj tsw qab ntawm alkaline (lossis cov tshuaj ethylene eporohydin). Noism soluble cellulose neeg hais txog. Since HEC has good properties of thickening, suspending, dispersing, emulsifying, bonding, film-forming, protecting moisture and providing protective colloid, it has been widely used in oil exploration, coatings, construction, medicine, food, textile, papermaking and polymer Polymerization and other fields. 40 Mesh sieving tus lej ≥ 99%;

Zog: dawb rau lub teeb daj fibrous lossis powdery cov khoom, tsis muaj tshuaj lom, ua rau muaj dej soluble. Insoluble nyob rau hauv cov organic cov kuab tshuaj.

Hydroxyethyl cellulose

Lub viscosity hloov me ntsis nyob rau hauv cov nqi ntawm PH tus nqi 2-12, tab sis cov viscosity txo dhau qhov no. Nws muaj cov khoom ntawm thickening, kev ncua, khi, emulsifying, dispersing, tswj kev noo thiab tiv thaiv kev sib deev. Cov kev daws teeb meem hauv kev sib txawv viscosity li cas tuaj yeem npaj tau. Tsis ruaj khov nyob rau hauv qhov kub thiab txias thiab lub zog, ua kom sov, thiab muaj qhov kub thiab txias, thiab nws cov kua ntsev kom zoo rau cov ntsev siab kom nyob ruaj khov

Cov khoom tseem ceeb: raws li tsis yog-ionic surfactant, hydroxyethyl cellulose muaj cov khoom siv hauv qab no ntxiv, ua yeeb yaj kiab, dej tuav thiab muab kev tiv thaiv kev tiv thaiv thiab muab kev tiv thaiv kev tiv thaiv

1. HEC yog soluble hauv dej kub lossis dej txias, thiab tsis precipitate ntawm qhov kub lossis rhaub, yog li nws muaj ntau yam ntawm solubility, thiab tsis yog-thermal gelation;

2. Nws yog tsis-ionic thiab tuaj yeem ua ke nrog ntau yam ntawm lwm cov dej-soluble polymers, solfactants, thiab ntsev. Nws yog ib qho zoo tshaj plaws colloidal thickener rau cov kev daws teeb meem elevelfolyte;

3

4. Piv nrog lees paub methyl cellulose thiab hydroxypropal methylropy, lub dispersing muaj peev xwm ntawm hac yog qhov phem tshaj, tab sis kev tiv thaiv kev tiv thaiv kev muaj peev xwm yog qhov muaj zog tshaj.

Daim Ntawv Thov Folding
Siv raws li cov nplaum, surfactant, colroid tiv thaiv tus neeg sawv cev, tsis txaus ntseeg, tshuaj pleev ib ce, tshuaj tua kab, tshuaj tua kab, cov tshuaj rho tawm thiab tshuaj.

1. Nws feem ntau yog siv los ua cov ntaub ntawv tuab, tiv thaiv, txhaws, pleev tshuaj, qhov muag ntxuav, thiab cov ntsiav tshuaj. Nws kuj tseem siv los ua cov khoom siv hydrophilic, kev npaj ua ke, kev npaj ua tiav-tso tawm, thiab tseem siv tau raws li lub stabilizer nyob rau hauv cov zaub mov.

2. Siv ua tus sawv cev Sizing hauv kev lag luam textile, thiab ua ib tus neeg sawv cev rau kev sib raug zoo, thickening, thiab stidilizing hauv cov khoom siv hluav taws xob thiab kev lag luam lub teeb.

3. Nws yog siv raws li cov tuab tuab thiab ua kom muaj kev puas tsuaj rau dej thiab cov kua dej ua tiav, thiab cov nyhuv tuab yog pom tseeb hauv cov kua dej brine. Nws kuj tseem siv tau raws li cov kua dej ploj rau cov roj kom zoo. Nws tuaj yeem hla nrog polyvalent hlau ions los ua ib qho gel.

4. Cov khoom no tau siv los ua tus disporant rau cov roj av roj-based gel fracturing kua, polystyrene thiab cov tshuaj polyvinyl thiab lwm yam los ntawm kev txwv. Nws kuj tseem siv tau ua cov thickenter thickener hauv kev lag luam pleev xim, cov xis mas anticoagulant thiab a noo noo defulion tus neeg saib xyuas hauv kev tsim kho. Ceramic Kev Lag Luam Glazing thiab Tshuaj Txhuam Hniav Blinder. Nws tseem dav siv hauv kev luam ntawv thiab dyeing, textiles, tshuaj, kev tu cev, luam yeeb, tshuaj tua kab, tshuaj tua kab thiab tua hluav taws.

5. Raws li surfactant, colloidal tiv thaiv tus neeg sawv cev, tshuaj, tshuaj tua kab, tshuaj tua kab, thiab lwm yam hauv kev siv tshuaj ntsuam cov roj kev tshawb nrhiav thiab kev lag luam machinery.

6. Hydroxyethyl cellulose muaj cov nquag dhia, thickening, khi, ua yeeb yam hauv cov khoom siv tshuaj thiab kev tiv thaiv hauv kev ua kua.

7. Nws yog siv ua polymeric dispersant rau kev siv roj av roj-raws li gel fracturing kua, polyvinyl chloride thiab polystyrene. Nws kuj tseem siv tau raws li cov tuab emulsion hauv kev lag luam pleev xim, cov xis mas cov tshuaj txhuam hniav thiab cov tshuaj txhuam hniav ntxiv rau hauv kev lag luam ceramic. Nws tseem dav siv nyob rau hauv kev lag luam ua teb xws li luam tawm thiab tawg, textiles, tshuaj, kev tu cev, luam yeeb thiab tshuaj tua kab.

Khoom Folding
1. HEC yog soluble hauv dej kub lossis dej txias, thiab tsis precipitate ntawm qhov kub lossis rhaub, yog li nws muaj ntau yam ntawm solubility, thiab tsis yog-thermal gelation;

2. Nws yog tsis-ionic thiab tuaj yeem uake nrog lwm cov dej-soluble polymers, solfactants thiab ntsev nyob rau hauv ntau yam. Nws yog ib qho zoo tshaj plaws colloidal thickener rau cov kev daws teeb meem muaj cov siab-siab cov dielessrics;

4. Piv nrog lees paub methyl cellulose thiab hydroxypropal methylropy, lub dispersing muaj peev xwm ntawm hac yog qhov phem tshaj, tab sis kev tiv thaiv kev tiv thaiv kev muaj peev xwm yog qhov muaj zog tshaj.

Yuav Siv Quav
ntxiv ncaj qha rau ntawm lub sijhawm ntau lawm

1. Ntxiv cov dej huv rau ib lub thoob loj nruab nrog lub siab shear tov.

2. Pib do txuas txuas ntxiv ntawm kev nrawm nrawm thiab maj mam sieve lub hydroxyethyl cellulose rau hauv kev daws qhov uayees.

3. Txuas ntxiv nplawm kom txog thaum txhua qhov sib luag tau tsau.

4. Tom qab ntawd ntxiv cov neeg sawv cev antifungal, alkaline additives xws li pigments, dispersing AIDS, dispersing dej, ammonia dej.

5. Do kom txog thaum tag nrho cov hydroxyethyl cellulose yog tag nrho cov kev daws teeb meem (lub viscosity ntawm kev ntxiv lwm cov khoom, thiab zom kom txog thaum cov khoom tiav.
