CMC siv hauv Kev Lag Luam Xim thiab Txheej Txheej

Xim qib carboxymethyl cellulose sodiummuaj zoo thickening, dispersity thiab stability, nws muaj peev xwm txhim kho lub viscosity thiab rheology ntawm txheej, yog li nws yog dav siv nyob rau hauv ntau yam txheej, latex coatings, dej-raws li sab nrauv thiab sab hauv txheej, casting coatings thiab thiaj li nyob.

Kev siv instantpleev xim Qib carboxymethyl cellulose:

Qhov kev daws teeb meem tam sim no txhais tau hais tias CMC hmoov tuaj yeem tawg thiab yaj sai sai hauv cov tshuaj aqueous ntawm chav tsev kub, uas yog qhov txawv ntawm cov pa hom maj mam yaj CMC (cov pa hom CMC xav tau tsawg kawg 2-3 teev ntawm high- ceev stirring kom yaj tag). Lub viscosity ntawm cov txheej txheem tam sim carboxymethyl cellulose CMC yuav tsis tuaj yeem ncav cuag nws qhov tseeb viscosity nrog rau kev tawg sai sai ntawm cov hmoov, thiab yuav nyob rau hauv 10-15 feeb tom qab dissolution ntawm viscosity, tsim kom muaj qhov tseeb viscosity tuaj yeem ua tiav cov colloid. . Tsis tas li ntawd, lub colloid stability ntawm instant CMC yog zoo dua li cov pa CMC nrog tib specifications.

Tam sim nosolublecarboxymethyl cellulose CMC yog dav siv nyob rau hauv txhua yam dej-raws li txheej, xws li dawb latex, latex xim, putty, nyem xim, ntuj pob zeb xim, thiab lwm yam.

Qhov zoo ntawmpleev xim Qib carboxymethyl cellulose:

A) Txheej tsis yog txheej txheej thiab tuaj yeem khaws cia rau lub sijhawm ntev;

B) Nws tuaj yeem muab cov khoom lag luam tshwj xeeb sai sai rau cov ntawv thov txheej hauv cov chaw tshwj xeeb;

C) Zoo kho cov rheology ntawm glaze slurry, yooj yim daim ntawv thov glaze, thiab ua rau glaze slurry nyob rau hauv ib tug ruaj khov dispersion xeev;

D) Txhim kho glaze zog thiab smoothness los tiv thaiv deglazing;

E) Ua kom cov txheej txheem luam ntawv hauv kev tsim cov ntawv luam tawm glaze, thiab cov qauv luam tawm kom meej thiab zoo nkauj;

F) Yuav tsis muaj kev thaiv nyob rau hauv cov txheej txheem luam ntawv glaze luam ntawv, CMC muaj dej solubility zoo thiab yuav luag tsis muaj cov tshuaj insoluble xws li fiber ntau impurities;

Xim qibCMCCarboxymethyl cellulose dissolution txoj kev:

Covpleev xim qib carboxymethyl cellulose yog tov ncaj qha nrog dej thiab npaj rau hauv cov kua nplaum rau kev siv tom qab. Qib nyob rau hauv cov txheej txheem txheej carboxymethyl cellulose muab tshuaj nplaum, ua ntej nrog kev sib xyaw cov khoom xyaw cog hauv lub tog raj kheej kom koom nrog qee qhov dej huv, nyob rau hauv qhov qhib hauv qab lub tshuab nplawm, txheej txheej ntawm carboxymethyl cellulose maj mam thiab sib npaug rau cov khoom xyaw hauv lub tog raj kheej. , do tas li, ua xim carboxymethyl cellulose thiab dej theem fusion, carboxymethyl cellulose tuaj yeem ua tiav txheej txheej txheej. Thaum melting ximqib carboxymethyl cellulose, yog vim li cas kom sib npaug sib npaug, thiab tas li nplawm, lub hom phiaj yog "tiv thaiv cov xim qib carboxymethyl fiber thiab dej sib ntsib, agglomeration, agglomeration, txo cov xim qib carboxymethyl cellulose solubility teeb meem", thiab txhim kho tus nqi ntawm cov xim qib carboxymethyl. cellulose. stirring lub sij hawm thiab xim qib carboxymethyl cellulose tiav dissolution lub sij hawm tsis zoo ib yam, yog ob lub tswv yim, feem ntau hais lus, stirring lub sij hawm luv dua li cov xim qib carboxymethyl cellulose tiav dissolution lub sij hawm, lub sij hawm yuav tsum tau nyob ntawm qhov xwm txheej tshwj xeeb.

Txiav txim siab lub sij hawm nplawm ntawm lub hauv paus ntawm: thaum carboxymethyl cellulose nyob rau hauv cov dej sib npaug dispersed, tsis muaj ib tug pom tseeb pob khoom, koj yuav tsum tsis txhob nplawm, kom carboxymethyl cellulose thiab dej nyob rau hauv ib tug zoo li qub lub xeev ntawm kev sib nrig sib nkag mus, kev sib nrig sib fusion.

Txiav txim siab cov carboxymethyl cellulose ua tiav kev tawg ntawm lub sijhawm xav tau raws li cov hauv qab no:

(1) xim qibCMCcarboxymethyl cellulose thiab dej yog sib koom ua ke, thiab tsis muaj cov kua dej sib cais ntawm lawv;

(2) Cov khoom sib xyaw ua ke yog nyob rau hauv ib lub xeev sib xws, thiab nto yog du;

(3) Cov xim sib xyaw ntawm aleurone yog ze rau qhov tsis muaj xim thiab pob tshab, thiab tsis muaj cov khoom siv hauv cov aleurone. Los ntawm qib ximCMCcarboxymethyl cellulose muab tso rau hauv lub tank sib tov nrog dej, mus rau qib ximCMCcarboxymethyl cellulose yaj tag, lub sij hawm yuav tsum tau ntawm 10 mus rau 20 teev.
