Txoj kev yooj yim txheeb xyuas ntawm hydroxypropyl methylcellulose

Cellulose siv dav hauv petrochemical, tshuaj, ntawv, tshuaj pleev ib ce, cov ntaub ntawv tsim kho, thiab lwm yam. Nws yog ib qho khoom siv ntau yam, thiab kev siv sib txawv muaj cov kev cai ua tau zoo sib txawv rau cov khoom cellulose.

Tsab xov xwm no feem ntau qhia txog kev siv thiab txoj kev txheeb xyuas zoo ntawm HPMC (hydroxypropyl methylcellulose ether), uas yog hom cellulose feem ntau siv rau hauv cov hmoov putty ib txwm muaj.

HPMC siv paj rwb zoo ua cov khoom siv tseem ceeb. Nws muaj kev ua tau zoo, tus nqi siab thiab tiv taus alkali zoo. Nws yog qhov tsim nyog rau cov putty tsis kam dej thiab polymer mortar ua los ntawm cement, lime calcium thiab lwm yam khoom siv alkaline muaj zog. Qhov viscosity ntau yog 40,000-200000S.

Cov hauv qab no yog ntau txoj hauv kev los sim qhov zoo ntawm hydroxypropyl methylcellulose uas Xiaobian tau sau tseg rau koj. Los kawm nrog Xiaobian ~

1. Dawb:

Tau kawg, qhov tseem ceeb tshaj plaws hauv kev txiav txim siab qhov zoo ntawm hydroxypropyl methylcellulose tsis tuaj yeem yog qhov dawb xwb. Qee cov chaw tsim khoom yuav ntxiv cov neeg sawv cev dawb hauv cov txheej txheem ntau lawm, hauv qhov no, qhov zoo tsis tuaj yeem txiav txim siab, tab sis qhov dawb ntawm cov hydroxypropyl methylcellulose zoo heev.

2. Kev Zoo:

Feem ntau, hydroxypropyl methylcellulose muaj qhov zoo ntawm 80 mesh, 100 mesh thiab 120 mesh. Qhov zoo ntawm cov khoom me me yog qhov zoo heev, thiab qhov solubility thiab kev khaws cia dej kuj zoo. Qhov no yog hydroxypropyl methylcellulose zoo.

3. Kev xa hluav taws xob:

Muab hydroxypropyl methylcellulose rau hauv dej thiab yaj rau ib lub sijhawm kom paub tseeb tias nws viscosity thiab transparency. Tom qab cov gel tsim, xyuas nws lub teeb transmittance, qhov zoo dua lub teeb transmittance, qhov siab dua cov khoom tsis yaj thiab purity.

4. Lub zog tshwj xeeb:

Qhov loj dua qhov hnyav tshwj xeeb, qhov zoo dua, vim tias qhov hnyav dua qhov hnyav tshwj xeeb, qhov siab dua ntawm cov ntsiab lus ntawm hydroxypropyl methyl hauv nws, qhov zoo dua qhov kev khaws cia dej.
