Kev kho kom zoo ntawm Hydroxyethyl cellulose

Kev kho kom zoo ntawmHydroxyethyl Cellulose(HEC) suav nrog kev ua cov khoom siv raw los txhim kho nws cov purity, sib xws, thiab cov khoom siv rau cov ntawv thov tshwj xeeb. Nov yog cov ntsiab lus ntawm cov txheej txheem kho kom zoo rau HEC:

1. Raw Material Xaiv:

Cov txheej txheem kho kom zoo pib nrog kev xaiv cov khoom zoo cellulose ua cov khoom siv raw. Cellulose tuaj yeem muab tau los ntawm ntau qhov chaw, xws li ntoo pulp, paj rwb linters, lossis lwm yam khoom siv cog.

2. Purification:

Cov khoom siv cellulose nyoos dhau mus ua kom huv kom tshem tawm cov impurities xws li lignin, hemicellulose, thiab lwm yam tsis-cellulosic Cheebtsam. Cov txheej txheem purification no feem ntau suav nrog kev ntxuav, tshuaj dawb, thiab tshuaj kho mob txhawm rau txhim kho cov purity ntawm cellulose.

3. Etherification:

Tom qab purification, cellulose yog chemically hloov los ntawm etherification los qhia hydroxyethyl pawg mus rau cellulose qaum, uas ua rau tsim hydroxyethyl Cellulose (HEC). Etherification cov tshuaj tiv thaiv feem ntau yog siv cov alkali hlau hydroxides thiab ethylene oxide los yog ethylene chlorohydrin.

4. Neutralization thiab ntxuav:

Tom qab etherification, cov tshuaj tiv thaiv sib tov yog neutralized kom tshem tawm cov alkali ntau dhau thiab kho cov pH. Cov khoom nruab nrab yog tom qab ntawd ntxuav kom huv si kom tshem tawm cov tshuaj seem thiab cov khoom siv los ntawm cov tshuaj tiv thaiv.

5. Lim thiab ziab:

Cov tshuaj HEC refined yog lim kom tshem tawm cov khoom seem lossis impurities. Tom qab pom, HEC cov tshuaj yuav tsum tau concentrated, yog tias tsim nyog, thiab tom qab ntawd qhuav kom tau txais daim ntawv kawg ntawm cov hmoov los yog granular ntawm HEC.

6. Kev Tswj Xyuas Zoo:

Thoob plaws hauv cov txheej txheem ua kom zoo dua qub, kev ntsuas kev tswj kom zoo yog siv los xyuas kom meej qhov sib xws, purity, thiab kev ua tau zoo ntawm HEC cov khoom. Kev ntsuas kev tswj xyuas zoo yuav suav nrog kev ntsuas viscosity, ntsuas qhov hnyav ntawm molecular, kev txiav txim siab cov dej noo, thiab lwm yam kev ntsuas lub cev thiab tshuaj.

7. Ntim thiab Cia:

Thaum ua kom zoo dua qub, cov khoom HEC tau ntim rau hauv cov thawv tsim nyog lossis lub hnab ntim khoom thiab thauj mus los. Kev ntim khoom kom zoo pab tiv thaiv HEC los ntawm kev sib kis, ya raws, thiab lwm yam ib puag ncig uas tuaj yeem cuam tshuam rau nws qhov zoo.

Daim ntawv thov:

Refined Hydroxyethyl Cellulose (HEC) pom ntau daim ntawv thov thoob plaws ntau yam kev lag luam, suav nrog:

• Kev tsim kho: Siv ua cov thickener, rheology modifier, thiab dej tuav tus neeg saib xyuas hauv cov khoom siv cement, xim, coatings, thiab adhesives.
• Kev Kho Tus Kheej thiab Kho Kom Zoo Nkauj: Siv los ua cov thickener, stabilizer, thiab zaj duab xis yav dhau los hauv cov tshuaj pleev ib ce, tshuaj zawv plaub hau, thiab lwm yam khoom siv tu tus kheej.
• Pharmaceutical: Siv los ua ib qho kev sib khi, disintegrant, thiab tswj-tso tawm tus neeg sawv cev hauv cov tshuaj ntsiav tshuaj, tshuaj ntsiav, thiab qhov ncauj tshem tawm.
• Khoom noj khoom haus: Ua hauj lwm raws li ib tug thickener, emulsifier, thiab stabilizer nyob rau hauv cov khoom noj xws li kua ntses, hnav khaub ncaws, thiab cov khoom noj siv mis.

Xaus:

Kev kho kom zoo ntawm Hydroxyethyl Cellulose (HEC) muaj ob peb kauj ruam los ntxuav thiab hloov cov khoom siv cellulose nyoos, ua rau muaj ntau yam thiab ua tau zoo polymer nrog ntau yam kev siv hauv kev lag luam xws li kev tsim kho, kev saib xyuas tus kheej, tshuaj, thiab zaub mov. Cov txheej txheem kho kom zoo kom ntseeg tau qhov sib xws, purity, thiab zoo ntawm HEC cov khoom, ua rau nws siv ntau yam formulations thiab cov khoom.
