Kev siv cov hydroxyethyl cellulose

Raws li cov tsis-ionic surfactant, hydroxyethyl cellulose muaj cov khoom nram qab no ntxiv rau kev ua haujlwm ntawm kev ncua, thickening, dispersing, floating, bonding, film forming, dej tuav thiab muab kev tiv thaiv colloid:

1. HEC yog soluble nyob rau hauv dej kub los yog dej txias, thiab tsis precipitate ntawm kub los yog boiling, kom nws muaj ib tug ntau yam ntawm solubility thiab viscosity yam ntxwv, thiab tsis-thermal gelation;

2. Piv nrog rau kev lees paub methyl cellulose thiab hydroxypropyl methyl cellulose, lub peev xwm dispersing ntawm HEC yog qhov phem tshaj, tab sis lub peev xwm tiv thaiv colloid yog qhov muaj zog tshaj.

3. Lub peev xwm tuav dej yog ob zaug siab dua li ntawm methyl cellulose, thiab nws muaj kev tswj xyuas zoo dua.

Kev ceev faj thaum siv:

Txij li qhov chaw kho hydroxyethyl cellulose yog hmoov los yog cellulose khoom, nws yog ib qho yooj yim los lis thiab yaj nws nyob rau hauv dej tsuav yog cov khoom nram qab no tau them nyiaj mloog mus rau.

1. Ua ntej thiab tom qab ntxiv hydroxyethyl cellulose, nws yuav tsum tau nplawm tas li kom txog rau thaum cov tshuaj yog pob tshab thiab meej.

2. Nws yuav tsum tau maj mam sifted rau hauv lub tank tov, tsis txhob ncaj qha ntxiv ib tug loj npaum li cas ntawm hydroxyethyl cellulose uas tau tsim lumps los yog pob rau hauv lub mixing tank.

3. Dej kub thiab PH tus nqi hauv dej muaj kev sib raug zoo rau kev sib cais ntawm hydroxyethyl cellulose, yog li yuav tsum tau them nyiaj tshwj xeeb.

4. Tsis txhob ntxiv qee cov tshuaj alkaline rau qhov sib tov ua ntej cov hmoov hydroxyethyl cellulose sov los ntawm dej. Nce tus nqi PH tom qab ua kom sov yuav pab yaj.

HEC siv:

1. Nws feem ntau yog siv los ua cov thickener, tiv thaiv tus neeg sawv cev, nplaum, stabilizer, thiab ntxiv rau kev npaj ntawm emulsions, jellies, tshuaj pleev, tshuaj pleev ib ce, tshuaj ntxuav qhov muag, suppositories thiab ntsiav tshuaj, thiab tseem siv los ua hydrophilic gel thiab pob txha cov ntaub ntawv, kev npaj ntawm matrix-hom sustained-tso npaj, thiab tseem tuaj yeem siv los ua kom ruaj khov hauv cov khoom noj.

2. Siv los ua tus neeg sawv cev sizing hauv kev lag luam textile, thiab ua tus neeg sawv cev pabcuam rau kev sib txuas, thickening, emulsifying, thiab stabilizing hauv electronics thiab light industry sectors.

3. Nws yog siv los ua thickener thiab kua poob reducer rau dej-raws li drilling kua thiab tiav kua, thiab cov thickening nyhuv yog pom tseeb nyob rau hauv brine drilling kua. Nws kuj tseem siv tau los ua cov kua dej poob qis rau cov roj zoo cement. Nws tuaj yeem txuas nrog polyvalent hlau ions los ua ib lub gel.

4. Cov khoom no yog siv los ua dispersant rau polymerization ntawm roj av-raws li gel fracturing kua, polystyrene thiab polyvinyl chloride, thiab lwm yam los ntawm fracturing. Nws kuj tseem tuaj yeem siv los ua emulsion thickener hauv kev lag luam xim, hygrostat hauv kev lag luam hluav taws xob, cov cement anticoagulant thiab cov neeg saib xyuas cov dej noo hauv kev tsim kho. Ceramic kev lag luam glazing thiab tshuaj txhuam hniav binder. Nws kuj yog siv dav hauv kev luam ntawv thiab dyeing, textiles, papermaking, tshuaj, tu cev, zaub mov, luam yeeb, tshuaj tua kab thiab tua hluav taws.
