Methyl cellulose ether

1. Cov yam ntxwv:

(1). Kev tuav dej: Txij li thaumMethyl cellulose etherCov khoom tuaj yeem nqus dej ntau, nws tuaj yeem khaws cov dej hauv mortar thiab gypsum.

(2). Puab tuav: nws cov kua dej aqueous muaj cov khoom tshwj xeeb viscoelastic, uas tuaj yeem tswj cov duab ntawm cov khoom siv ceramic.

(3). Lubricity: MC tuaj yeem txo qhov kev sib txhuam coefficient thiab txhim kho lub lubricating kev ua tau zoo ntawm ceramic thiab pob zeb khoom.

(4). PH tus nqi ruaj ntseg: viscosity ntawm aqueous tov tsis tshua muaj kev cuam tshuam los ntawm acid lossis alkali. Nws cov tshuaj aqueous tseem nyob ruaj khov tshaj pH dav, feem ntau ntawm 3.0 thiab 11.0.

(5). Zaj duab xis-tsim cov khoom: MC tuaj yeem tsim cov khoom, hloov tau yooj yim thiab pob tshab nrog cov roj zoo.

2. Molecular formula:

N: degree ntawm polymerization; R: -H, -CH3 lossis CH2CHOHCH3

3. Lub cev thiab tshuaj muaj zog

Txoj kev Dissolving:

Ua ntej sov dej rau 80-90 ° C, maj mam ntxiv MC nyob rau hauv tas li stirring, tos kom qhov kub thiab txias poob, ces txias los tsim ib tug uniform aqueous tov. Los yog ntxiv ib feem peb mus rau ob feem peb ntawm cov dej uas yuav tsum tau ua ntej, kub rau 80-90 ° C, maj mam ntxiv MC nyob rau hauv tas li stirring, tom qab nthuav, ntxiv cov dej txias ntxiv, thiab txias.
