Puas yog hydroxypropal methylcellulose yuav siv los ua cov kua nplaum?

Ua ntej tshaj plaws, qib ntawm kev siv kua nplaum yuav tsum tau coj mus rau hauv tus account cov ntaub ntawv raw. Qhov laj thawj tseem ceeb rau cov txheej txheej kua nplaum yog qhov tsis sib xws ntawm cov acrylic emulsion thiab hydroxypropylulose (HPMC). Thib ob, vim tsis muaj kev sib xyaw ua ke; Kuj tseem tsis zoo ua tuab ua kev ua tau zoo ntawm kev siv kua nplaum. Hauv kev siv cov kua nplaum, koj yuav tsum siv Instant Hydroxyprropylropylropylrope (HPMC), vim HPMC), vim HPMC tsuas yog dispersed hauv dej, nws tsis paub tiag tiag. Tom qab txog 2 feeb, lub viscosity ntawm cov kua maj mam nce, ua ib qho kev daws teeb meem viscous kiag li. Cov khoom kub kub yaj, thaum raug dej txias, tuaj yeem tawg sai nyob rau hauv cov dej npau thiab ploj hauv dej npau. Thaum qhov kub thiab txias rau ib qho kub thiab txias, maj mam pom maj mam tshwm sim kom txog thaum muaj kev daws teeb meem viscous loj heev yog tsim tawm. Kev ua tau zoo ntawm HydroxyPropyyl methylcellose (HPMC) hauv cov kua nplaum siv yog 2-4kg.

HydroxyPropyyl methylulose (HPMC) tau ruaj khov lub cev hauv kev tsim kho cov nplaum, thiab muaj cov nyhuv zoo heev ntawm cov dej khov thiab yuav tsis cuam tshuam los ntawm kev hloov pauv ntawm PH nqi. Lub viscosity tuaj yeem siv ntawm 100,000 s thiab 200,000 s. Hauv kev tsim khoom, qhov siab dua viscosity, qhov zoo dua. Viscosity yog inversely perctional rau tus thwj compressive zog. Qhov siab tshaj lub viscosity, txo qis dua lub zog compressive. Feem ntau, cov viscosity ntawm 100,000 s yog qhov tsim nyog.

Mix CMC nrog dej thiab ua cov nyom muddy rau kev siv tom qab. Thaum txhim kho CMC Muab tshuaj txhuam, ntxiv qee qhov dej txias rau lub tanking tank nrog lub tshuab stiring. Thaum lub tshuab stringing pib, maj mam thiab tusyees sprinkle lub carboxymethyl cellulose rau hauv lub tanking thiab txuas ntxiv ua tiav, thiab cov roj carboxymethyl ntawm cellulose yog rhuav tshem. Thaum dissolving tus CMC, nws yog feem ntau tsim nyog rau disperse thiab sib txuas tsis tu ncua, thiab txo cov teeb meem ntawm cmc sib txawv "thiab nce cov kev sib cais ntawm CMC.

Lub sijhawm sib xyaw tsis yog tib yam li lub sijhawm rau CMC kom yaj tag. yog 2 txhais. Feem ntau hais lus, lub sijhawm sib xyaw muaj ntau luv luv dua li lub sijhawm rau CMC kom ua tiav tag, nws nyob ntawm cov ntsiab lus. Lub hauv paus rau kev txiav txim rau lub sijhawm sib xyaw yog thaum CMC yog uniformly dispersed hauv cov kua tsis pom tseeb, yog li ntawd, yog li ntawd rau kev nkag mus rau hauv txhua lwm yam nyob hauv cov ntaub ntawv qub. Muaj ntau cov laj thawj rau kev txiav txim siab lub sijhawm uas yuav tsum tau ua kom tiav ntawm CMC:

(1) CMC thiab dej tau ua tiav, thiab tsis muaj cov khoom sib cais ua kua ntawm lawv;
(2) Cov khoom xyaw sib xyaw yog cov khoom siv tau zoo thiab ib txwm muaj, nrog txoj kev du thiab du;
(3) Cov tshuaj sib xyaw tsis muaj xim thiab pob tshab tag nrho, thiab tsis muaj ib qho hauv cov tshuaj txhuam. Nws yuav siv sijhawm 10 txog 20 teev txij li lub sijhawm CMC tau muab tso rau hauv lub tank batching thiab sib xyaw nrog dej kom txog thaum nws yaj tag.
