HEC rau cov khoom lag luam tshwj xeeb qib pleev xim

HydroxyethylcelluloseHECyog ib qho polymer uas tsis yog ionic uas yaj tau hauv dej kub thiab dej txias. Hydroxyethylcellulose series HEC muaj ntau yam viscosities, thiab cov kua dej yog cov kua dej uas tsis yog Newtonian.

Hydroxyethyl cellulose yog ib qho khoom siv tseem ceeb hauv cov khoom siv tshuaj txhua hnub. Nws tsis tsuas yog txhim kho qhov viscosity ntawm cov kua lossis emulsion tshuaj pleev ib ce, tab sis kuj txhim kho kev sib kis thiab kev ruaj khov ntawm cov ua npuas ncauj.

qhov zoo dua:
1. Muaj dej noo zoo heev.
2. Muaj kev sib xws zoo thiab puv npo.
3. Cov khoom zoo heev uas ua rau zaj duab xis zoo nkauj.
4. Nws muaj kev ua tau zoo heev.
5. Nws muaj ib qho kev hloov pauv zoo heev los xyuas kom meej tias cov khoom tsis yooj yim puas tsuaj mus sij hawm ntev.

Qib polymerization:
Muaj peb pawg hydroxyl ntawm txhua chav anhydroglucose hauv cellulose, uas tau kho nrog alkali hauv cov kua sodium hydroxide kom tau txais cellulose sodium ntsev, thiab tom qab ntawd dhau los ua etherification reaction nrog ethylene oxide los tsim hydroxyethyl cellulose ether. Hauv cov txheej txheem ntawm kev tsim hydroxyethyl cellulose, ethylene oxide tuaj yeem hloov cov hydroxyl pawg ntawm cellulose, thiab dhau los ua cov saw polymerization reaction nrog cov hydroxyl pawg hauv cov pab pawg hloov pauv.

Hydroxyethylcellulose muaj cov khoom zoo heev rau kev ntub dej. Nws cov kua dej yog du thiab sib xws, nrog rau kev ua kom zoo thiab sib npaug. Yog li ntawd, cov tshuaj pleev ib ce uas muaj hydroxyethyl cellulose muaj qhov sib xws zoo thiab puv hauv lub thawv, thiab kis tau yooj yim rau ntawm cov plaub hau thiab daim tawv nqaij thaum siv. Siv dav hauv cov tshuaj pleev ib ce, tshuaj ntxuav lub cev, xab npum ua kua, cov tshuaj zawv plaub hau thiab cov ua npuas dej, tshuaj txhuam hniav, cov tshuaj tsw qab tiv thaiv hws, cov ntaub so ntswg (menyuam yaus thiab cov neeg laus), cov tshuaj nplaum.

Ntxiv rau kev tswj cov kua dej,hydroxyethyl cellulosemuaj cov yam ntxwv zoo heev rau kev tsim cov zaj duab xis. Cov zaj duab xis uas tsim tau lees tias yuav nyob rau hauv lub xeev tiav hauv qab 350x thiab 3500x daim iav scanning, thiab nws coj cov tawv nqaij zoo heev thaum siv rau cov tshuaj pleev ib ce.
