HEC qib zoo nkauj

Hydroxyethyl cellulose, hu ua HEC, cov tsos ntawm cov khoom dawb lossis daj daj fibrous khoom lossis hmoov khoom, tsis muaj tshuaj lom thiab tsis qab, yog cov khoom tsis-ionic cellulose ether. Hydroxyethyl cellulose yooj yim soluble hauv dej, ob qho tib si dej txias thiab dej kub tuaj yeem yaj, cov kua dej tsis muaj cov khoom gel, muaj kev nplaum zoo, tiv taus cua sov, tsis yaj hauv cov kuab tshuaj organic dav dav. Hydroxyethyl cellulose yog ib qho tseem ceeb hauv dej-soluble cellulose ether thib ob tsuas yog carboxymethyl cellulose thiab hydroxypropyl methyl cellulose hauv kev lag luam thoob ntiaj teb.

Tshuaj pleev ib ce qibHEC Hydroxyethyl cellulose hydroxyethyl cellulose yog ib qho tshuaj ua kom cov yeeb yaj kiab zoo, nplaum, ua kom tuab, stabilizer thiab dispersant hauv tshuaj zawv plaub hau, tshuaj tsuag plaub hau, neutralizer, kev saib xyuas plaub hau thiab tshuaj pleev ib ce. Hauv cov hmoov ntxhua khaub ncaws yog ib hom av rov qab - tus neeg sawv cev; Cov tshuaj ntxuav uas muaj hydroxyethyl cellulose muaj qhov pom tseeb ntawm kev txhim kho qhov du thiab mercerization ntawm cov ntaub.

Tshuaj pleev ib ce qibTxoj kev npaj HEC Hydroxyethyl cellulose yog muab cov ntoo pulp, paj rwb thiab sodium hydroxide reaction, kom tau txais cov khoom ntawm alkali cellulose ua raw khoom, tom qab smashing rau hauv lub lauj kaub tshuaj tiv thaiv, nyob rau hauv lub tshuab nqus tsev hauv nitrogen, thiab koom nrog epoxy ethane raw kua tshuaj tiv thaiv yog, tig ntxiv ethanol, acetic acid, glyoxal, ntxuav, neutralization thiab crosslinking tshuaj tiv thaiv ntawm kev laus, Thaum kawg, cov khoom tiav lawm yog npaj los ntawm kev ntxuav, dehydration thiab ziab.

Tshuaj pleev ib ce qibHEC Hydroxyethyl cellulose nrog cov thickening, bonding, emulsion, suspension, zaj duab xis forming, water retention, anti-corrosion, stability thiab lwm yam ntxwv, tuaj yeem siv dav hauv cov roj drilling kua ntawm thickening agent, dispersant, xim thiab cov khoom siv kua mem thickener, stabilizer, resin, yas ntau lawm ntawm dispersant, textile sizing agent, cov ntaub ntawv tsim kho xws li cement thiab gypsum binder, thickener, dej retention agent, Suspending agent thiab surfactant rau cov khoom siv tshuaj txhua hnub, sustained release agent rau kev lag luam tshuaj, zaj duab xis txheej rau ntsiav tshuaj, blocker rau cov ntaub ntawv pob txha, nplaum thiab stabilizer rau kev lag luam hluav taws xob, thiab lwm yam.

Hauv kev lag luam hauv Suav teb, kev siv hydroxyethyl cellulose feem ntau yog siv rau hauv cov tshuaj pleev xim, cov tshuaj siv niaj hnub, roj av thiab lwm yam lag luam, thiab tsawg dua hauv lwm qhov chaw. Tsis tas li ntawd, kev tsim cov hydroxyethyl cellulose hauv Suav teb feem ntau yog cov khoom lag luam qis, thiab nws daim ntawv thov feem ntau yog siv rau hauv cov tshuaj pleev xim qis thiab cov khoom lag luam tshuaj siv niaj hnub. Hauv kev lag luam siab, tus naj npawb ntawm cov tuam txhab lag luam hauv Suav teb me me, cov zis tsis txaus, thiab kev vam khom sab nraud loj heev. Tsav los ntawm kev hloov pauv sab kev muab khoom thiab cov cai tiv thaiv ib puag ncig, Tuam Tshoj cov qauv kev lag luam hydroxyethyl cellulose pheej hloov kho thiab txhim kho tas li, thiab tus nqi hauv zos ntawm kev lag luam siab yuav txuas ntxiv txhim kho yav tom ntej.

Cov Khoom Siv Tshuaj

Cov khoom Cov Qib 

HECHydroxyethyl cellulose yog ib yam khoom tseem ceeb ntawm cellulose ether uas tau qeb thib peb hauv kev tsim khoom thiab muag khoom thoob ntiaj teb. Nws yog cov cellulose uas yaj tau hauv dej thiab tsis yog ionic, uas siv tau dav hauv roj av, xim, luam ntawv, textile, cov ntaub ntawv siv hauv tsev, tshuaj txhua hnub, tshuaj, khoom siv hluav taws xob thiab lwm yam lag luam, nrog rau kev lag luam dav dav. Vim muaj kev thov ntau, cov khoom tsim tawm ntawm hydroxyethyl cellulose hauv Suav teb tab tom nce siab. Nrog rau kev txhim kho kev siv thiab kev tswj hwm cov cai tiv thaiv ib puag ncig, kev lag luam tab tom txhim kho mus rau qib siab. Cov lag luam uas tsis tuaj yeem ua raws li qhov kev loj hlob yav tom ntej yuav raug tshem tawm maj mam.

Hydroxyethyl cellulose hauv cov tshuaj pleev ib ce, cov khoom saib xyuas tawv nqaij yog lub luag haujlwm tseem ceeb ntawm cov plaub hau txias, zaj duab xis tsim tus neeg sawv cev, emulsifying stabilizer, nplaum, qhov txaus ntshai yog 1, muaj kev nyab xeeb, tuaj yeem so kom paub tseeb tias siv, rau cov poj niam cev xeeb tub feem ntau tsis muaj kev cuam tshuam, hydroxyethyl cellulose tsis muaj pob txuv ua rau.

Hydroxyethyl cellulose yog cov nplaum polymer hluavtaws siv hauv cov tshuaj pleev ib ce ua cov tshuaj pleev tawv nqaij, tus neeg sawv cev tsim zaj duab xis thiab antioxidant.

Cov teeb meem yuav tsum tau sau tseg thaum sivkev zoo nkaujqib HEChydroxyethyl cellulose:

1. Ua ntej thiab tom qab ntxiv cov tshuaj pleev ib ce HEC hydroxyethyl cellulose, yuav tsum tau do kom txog thaum cov tshuaj no pob tshab thiab meej.

2. Siv lub tshuab lim dejHEC qib zoo nkaujmaj mam ntxiv hydroxyethyl cellulose rau hauv lub thawv sib tov. Tsis txhob ntxiv ntau dhau los yog ntxiv ncaj qha rau hauv lub thawv sib tov.

3. Qhov yaj ntawmkev zoo nkaujqibHEChydroxyethyl cellulose yog qhov tseeb cuam tshuam nrog dej kub thiab PH tus nqi, yog li yuav tsum tau them sai sai rau nws.

4. Tsis txhob ntxiv cov tshuaj alkaline rau hauv cov khoom sib tov ua ntej cov hmoov hydroxyethyl cellulose tau txias hauv dej. Kev nce tus nqi PH tom qab ua kom sov pab yaj.

5. Yog tias ua tau, ntxiv cov tshuaj tua kab mob mildew thaum ntxov.

6. Thaum siv cov tshuaj pleev ib ce HEC hydroxyethyl cellulose uas muaj viscosity siab, qhov concentration ntawm cov dej cawv niam yuav tsum tsis txhob siab tshaj 2.5-3%, txwv tsis pub cov dej cawv niam nyuaj rau kev ua haujlwm. Cov hydroxyethyl cellulose tom qab kho feem ntau tsis yooj yim los ua cov clumps lossis spheres, thiab nws yuav tsis tsim cov insoluble spherical colloids tom qab ntxiv dej.
