Ubumenyi buzwi | Nubuhe buryo bwo gusesa methyl selulose?

Ku bijyanye no gukomera kwa methyl selulose, bivuga cyane cyane gukomera kwa sodium carboxymethyl selulose.

Sodium carboxymethyl selulose ni ifu ya fibre yera cyangwa yumuhondo, idafite impumuro nziza kandi itaryoshye. Irashobora gushonga byoroshye mumazi akonje cyangwa ashyushye, ikora igisubizo kiboneye hamwe nubwiza runaka.

Gukemura ni iki? Mubyukuri, bivuga ubwinshi bwa solute yashongeshejwe nibintu bikomeye muburyo bugereranije bwuzuye muri 100g yumuti mubushyuhe runaka. Ubu ni igisubizo. Ubushobozi bwa methyl selulose bufitanye isano nibintu bibiri. Ku ruhande rumwe, biterwa nibiranga carboxymethyl selulose, naho kurundi ruhande, ifitanye isano rito nubushyuhe bwo hanze, ubushuhe, umuvuduko, ubwoko bwa solvent, nibindi. ubushyuhe, kandi biziyongera hamwe no kwiyongera k'ubushyuhe.

Hariho uburyo butatu bwo gushonga methylcellulose:

1. Uburyo bwo guhanagura ibishishwa. Ubu buryo ni ugukwirakwiza cyangwa gutose MC yumuti wa organic nka Ethanol na Ethylene glycol mbere, hanyuma ukongeramo amazi kugirango ushonga.

2. Uburyo bwamazi ashyushye. Kubera ko MC idashonga mumazi ashyushye, MC irashobora gukwirakwizwa neza mumazi ashyushye mugihe cyambere. Iyo ukonje, uburyo bubiri bukurikira burashobora gukurikizwa:

(1) Urashobora kubanza kongeramo amazi akwiye mubikoresho hanyuma ukabishyushya kuri 70 ° C. MC yongeweho buhoro buhoro hamwe no gukurura buhoro, buhoro buhoro ikora ibishishwa, hanyuma bikonjeshwa no gukurura.

. hanyuma ubyongere mumazi akonje Jya kuri slurry, koga neza hanyuma ukonje imvange.

3. Uburyo bwo kuvanga ifu. Ubu buryo ni ugukwirakwiza ibice by'ifu ya MC hamwe n'ibikoresho by'ifu bingana kuvanga byumye, hanyuma ukongeramo amazi gushonga.
