Qib ntawm cov tsev nplaum nplaum yog qhov teeb meem rau cov neeg siv khoom. Ua ntej, theem ntawm lub tsev nplaum yuav tsum tau coj mus rau hauv tus account cov khoom siv raw. Qhov tseem ceeb tshaj plaws rau lub tsev nplaum ua kom tiav 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 rau cov yam ntxwv ua kom zoo ntawm lub tsev nplaum. Nyob rau hauv tsev nplaum, nws yog ib qho tseem ceeb kom siv cov kas fes hydroxypropylropen (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, tsim tau cov kev daws teeb meem zoo nkauj ua kom khov. Kub Melt cov khoom lag luam, ntsib dej txias, tuaj yeem sai sai tawg hauv dej npau, hauv dej npau. Thaum qhov kub thiab txias rau qhov kub thiab txias, ntsuas kub, viscosity rov qab tshwm sim kom txog thaum muaj kev daws teeb meem viscous loj heev yog tsim tawm. Lub tsev nplaum hydroxypropyl cellulose (HPMC) hauv kev pom zoo ntau ntawm 2-4 kg.
HydroxyPropy cellulose (HPMC) nyob rau hauv lub cev kua qaub nyob hauv nruab nrab ntawm 100,000 s tab sis kev tsim khoom thiab kev tsim khoom, siab dua qhov zoo dua viscosity. Viscosity yog inversely proportional rau Adhesive lub zog. Qhov siab tshaj lub viscosity, txo qis dua lub zog compressive. Kev viscosity 100,000 s yog qhov tsim nyog.
Tam sim no kho kom zoo rau kev lag luam, hydroxypropal methylropy cellulose daim ntawv thov yog nruj dua.
Yuav ua li cas thiaj muaj nuj nqis no ua tau txiav txim siab? Coj koj mus txog:
Tam sim ntawd sib xyaw CMC nrog dej los ua cov av nkos nplaum tshwj tseg. Thaum txhim kho CMC muab tshuaj txhuam, qee qhov nyiaj ntawm cov dej txias tau ntxiv rau lub lauj kaub ua ke nrog lub tshuab stiring. Thaum lub tshuab stirring pib, carboxymethyl cellulose maj mam thiab tusyees sprinkled thiab dej kom sib xyaw, fusent fused, cellule cellulose khaws cia. Thaum dissolving Pawg Neeg Tswj Xyuas, feem ntau nws yog qhov tsim nyog rau kev txiav txim siab ntawm cov kev tswj hwm kev sib ntsib ntawm cov kev tswj hwm ntawm pawg neeg tswj hwm kev tswj hwm.
Lub sijhawm sib xyaw sib txawv sib txawv ntawm lub sijhawm rau CMC kom yaj tag. Nws yog ob txhais. Feem ntau, lub sijhawm sib xyaw yog luv dua li lub sijhawm rau lub CMC kom yaj tag, nyob ntawm cov ntsiab lus. Kev txiav txim siab ntawm lub sijhawm sib xyaw ua ke yog ua kom muaj peev xwm txiav tawm cov dej tsis muaj txiaj ntsig, tso cai rau cov dej CMC thiab dej los rau txhua lwm yam hauv cov qauv ntaub ntawv zoo li qub. Daws lub sijhawm xav tau rau cmc kom yaj tag rau ntau yam:
(1) cmc thiab dej yog fused kiag li, thiab tsis muaj cov khoom siv ua kua sib cais ntawm txhua lwm yam;
(2) Cov sib tov yog qhov zoo ib yam thiab dav dav, thiab txheej txheej saum npoo yog tus thiab noo;
(3) Tom qab sib tov, cov tshuaj txhuam tsis muaj xim thiab yog pob tshab tag nrho, thiab tsis muaj kev cuam tshuam teeb meem hauv cov tshuaj txhuam. Los ntawm CMC Fund Cov tswv yim Cov khoom yuav khoom xyaw Tank thiab cov dej sib tov ua kom tiav cov kev yuav tsum yog 10 ~ 20 teev.
