Methyl cellulose ether

1.Zvinhu:

(1). Kuchengetwa kwemvura: KubvaMethyl cellulose etherchigadzirwa chinogona kutora huwandu hwemvura, chinogona kuchengetedza mvura mudhaka uye gypsum.

(2). Kuchengetwa kwechimiro: mhinduro yemvura ine yakakosha viscoelastic properties, iyo inogona kuchengetedza chimiro chezvigadzirwa zveceramic.

(3). Lubricity: MC inogona kuderedza friction coefficient uye kunatsiridza kuita kwekuzora kweceramic uye kongiri zvigadzirwa.

(4). PH kukosha kugadzikana: iyo viscosity yeaqueous solution haina kukanganiswa neasidhi kana alkali. Mhinduro yayo ine aqueous inoramba yakagadzikana pamusoro pehupamhi pH renji, kazhinji pakati pe3.0 ne11.0.

(5). Mafirimu-ekugadzira zvimiro: MC inogona kuumba yakasimba, inochinjika uye yakajeka firimu ine yakanaka mafuta kuramba.

2.Molecular formula:

N: dhigirii repolymerization;R: -H, -CH3 kana CH2CHOHCH3

3.Physical uye Chemical Properties

Dissolving nzira:

Kutanga kupisa mvura kusvika ku80-90 ° C, zvishoma nezvishoma uwedzere MC pasi pekusimudzira kunoramba kuchiita, kumirira kuti kutonhora kudonhe, uye kunotonhorera kuumba yunifomu yemvura inogadzirisa. Kana kuwedzera chikamu chimwe chete muzvitatu kune zviviri kubva muzvitatu zvemvura inodiwa kutanga, kupisa kusvika ku80-90 ° C, zvishoma nezvishoma kuwedzera MC pasi pekukurudzira nguva dzose, mushure mekuwedzera, kuwedzera mvura inotonhora yakasara, uye inotonhorera pasi.
