Ingaruka yibyibushye ya selile

Cellulose etheritanga minisiteri itose hamwe nubwiza buhebuje, bushobora kongera cyane ubushobozi bwo guhuza hagati ya minisiteri itose hamwe nigitereko fatizo, kandi bigateza imbere imikorere ya anti-sag ya minisiteri. Ikoreshwa cyane mugupompa minisiteri, sisitemu yo gukingira urukuta rwo hanze hamwe namatafari ahuza amatafari. Ingaruka yibyibushye ya selile ya selile irashobora kandi kongera ubushobozi bwa homogeneity hamwe no kurwanya-gukwirakwiza ibikoresho bishya bivanze na sima, bikarinda gusibanganya, gutandukanya no kuva amaraso ya minisiteri na beto, kandi birashobora gukoreshwa muri beto ya fibre, beto yo mumazi no kwikuramo beto. .

Ether ya selulose yongerera ubwiza bwibikoresho bishingiye kuri sima bivuye mubwiza bwumuti wa selile. Ironderero rya "viscosity" mubusanzwe rikoreshwa mugusuzuma ubwiza bwa selile ether igisubizo. Ubukonje bwa ether ya selile muri rusange bivuga igisubizo cya selile ya ether hamwe nibitekerezo bimwe (nka 2%). Umuvuduko (cyangwa igipimo cyo kuzunguruka, nka 20 rpm), agaciro ka viscosity gupimwa nigikoresho cyapimwe cyagenwe (nka viscometer izenguruka).

Viscosity nikintu cyingenzi cyo gusuzuma imikorere ya selile ether. Iyo hejuru ya viscosity ya selulose ether igisubizo, niko ubwiza bwibikoresho bishingiye kuri sima, niko bigenda bifata neza kuri substrate, kandi nubushobozi bukomeye bwo kurwanya kugabanuka no kurwanya gutatanya. Niba ububobere bwayo buri hejuru cyane, bizagira ingaruka kumikorere no mumikorere yibikoresho bishingiye kuri sima (nko gufata ibyuma byo guhomesha mugihe cyo kubaka amabuye ya minisiteri). Kubwibyo, ubwiza bwa selile ya selile ikoreshwa muri minisiteri yumye ivanze ni 15,000 ~ 60.000 mPa. S.

Byongeye kandi, umubyibuho ukabije wa selile ya selile yongerera amazi amazi ibikoresho bishingiye kuri sima, bityo umusaruro wa minisiteri ukiyongera.

Ubwiza bwumuti wa selile ether biterwa nibintu bikurikira:

Uburemere bwa molekuline (cyangwa urwego rwa polymerisiyasi) hamwe nubushuhe bwa selile ya selile, ubushyuhe bwumuti, igipimo cyogukoresha nuburyo bwo gupima.

1. Urwego rwo hejuru rwa polymerisation ya selile ya ether, niko uburemere bwa molekile, nubunini bwumuti wibisubizo byamazi;

2. Iyo hejuru ya dosage (cyangwa concentration) ya selile ya ether, niko hejuru yubukonje bwumuti wamazi wacyo, ariko hagomba kwitonderwa guhitamo dosiye ikwiye mugihe uyikoresheje, kugirango bitagira ingaruka kumikorere ya minisiteri na beto niba the dosiye ni ndende cyane;

3. Kimwe n’amazi menshi, ubwiza bwumuti wa selile ether bizagabanuka hamwe no kwiyongera kwubushyuhe, kandi nubushuhe bwa selile ya selile, niko ingaruka zubushyuhe ninshi;

4. Cellulose ether igisubizo mubisanzwe ni pseudoplastique, ifite umutungo wo kogosha. Ninshi igipimo cyogosha mugihe cyikizamini, niko kugabanuka kwijimye.

Kubwibyo rero, guhuriza hamwe kwa minisiteri bizagabanuka bitewe nimbaraga zo hanze, zifitiye akamaro ko kubaka ibisasu bya minisiteri, kugirango minisiteri ibashe gukora neza no guhuriza hamwe icyarimwe. Nyamara, umuti wa selulose ether uzagaragaza ibiranga amazi ya Newtonian mugihe intumbero iba mike cyane kandi viscosity ni nto. Iyo kwibandaho kwiyongera, igisubizo kizagenda kigaragaza buhoro buhoro ibiranga amazi ya pseudoplastique, kandi nubunini bwinshi, niko bigaragara pseudoplastique.
