Methyl selulose ether

1.Ibiranga:

(1). Kubika amazi: KuvaMethyl selulose etheribicuruzwa birashobora gukuramo amazi menshi, birashobora kugumana neza amazi muri minisiteri na gypsumu.

(2). Kugumana imiterere: igisubizo cyamazi yacyo gifite imiterere yihariye ya viscoelastic, ishobora kugumana imiterere yibicuruzwa byubutaka.

(3). Amavuta: MC irashobora kugabanya coefficente yo guterana no kunoza imikorere yo gusiga ibicuruzwa bya ceramic na beto.

(4). PH agaciro gahamye: ubwiza bwumuti wamazi ntibugerwaho na aside cyangwa alkali. Igisubizo cyacyo cyamazi gikomeza guhagarara neza mugice kinini cya pH, muri rusange hagati ya 3.0 na 11.0.

(5). Imiterere yo gukora firime: MC irashobora gukora firime ihamye, yoroheje kandi ibonerana hamwe na peteroli nziza.

2.Imikorere ya molekulari:

N: urwego rwa polymerisation; R: -H, -CH3 cyangwa CH2CHOHCH3

3.Ibintu bya fiziki na shimi

Uburyo bwo gusesa:

Banza ushushe amazi kuri 80-90 ° C, ongeramo buhoro MC munsi yikurikiranya, utegereze ko ubushyuhe bugabanuka, hanyuma ukonje kugirango ube igisubizo kimwe cyamazi. Cyangwa ongeramo kimwe cya gatatu kugeza kuri bibiri bya gatatu byamazi asabwa mbere, shyushya 80-90 ° C, shyiramo buhoro buhoro MC uhora ubyutsa, nyuma yo kwaguka, ongeramo amazi akonje asigaye, hanyuma ukonje.
