Ni ibihe bintu bizagira ingaruka ku bwiza bwa hydroxypropyl methylcellulose?

Mugukoresha minisiteri itose, hydroxypropyl methylcellulose ifite imiterere myiza yo kubyimba, irashobora kongera cyane ubushobozi bwo guhuza hagati ya minisiteri itose hamwe nigitereko fatizo, kandi irashobora no kunoza imikorere ya anti-sag ya minisiteri, bityo ikoreshwa cyane muguhomesha Mortar, hanze sisitemu yo gukingira urukuta hamwe n'amatafari ahuza amatafari.

Kugirango habeho umubyimba wa selile ya selile, irashobora kandi kongera ubushobozi bwa homogeneity hamwe no kurwanya-gukwirakwiza ibikoresho bishya bivanze na sima, kandi birashobora no gukumira ibibazo byo gusenya, gutandukanya no kuva amaraso muri minisiteri na beto. Irashobora gukoreshwa kuri Fibre-fer-beto, beto yo mumazi hamwe na beto yonyine.

Hydroxypropyl methylcellulose irashobora kongera imikorere yimikorere yibikoresho bishingiye kuri sima. Iyi mikorere ituruka cyane cyane kuri viscosity ya selulose ether igisubizo. Mubisanzwe, imibare yimibare yubukorikori ikoreshwa mugucira urubanza ubukonje bwumuti wa selile, mugihe selileose Ubusembwa bwa ether mubisanzwe bivuga cyane cyane kwibanda kumuti wa selile ya selile, mubisanzwe 2%, mubushyuhe bwihariye, nka dogere 20 na igipimo cyo kuzunguruka, ukoresheje igikoresho cyapimwe cyagenwe, nka viscometer izunguruka. Agaciro.

Viscosity nimwe mubintu byingenzi byo gusuzuma imikorere ya selile ether. Iyo hejuru ya viscosity ya hydroxypropyl methylcellulose yumuti, niko ubwiza bwibikoresho bishingiye kuri sima, nuburyo bwiza bwo gufatira kuri substrate. Muri icyo gihe, ifite ubushobozi bwo kurwanya-kugabanuka hamwe nubushobozi bwo kurwanya-gutatanya birakomeye, ariko niba ubukonje bwabwo buri hejuru cyane, bizagira ingaruka kumikorere no mumikorere yibikoresho bishingiye kuri sima.

Ni ibihe bintu bizagira ingaruka ku bwiza bwa hydroxypropyl methylcellulose? Ahanini biterwa nimpamvu zikurikira.

1.

2. Niba ingano cyangwa ubunini bwa selulose ether ari byinshi, ubwiza bwumuti wamazi wabwo buzaba bwinshi. Ariko rero, hakwiye kwitonderwa guhitamo urugero rukwiye rwa selile ya selile mugihe uyikoresheje, cyane cyane kugirango wirinde urugero rwinshi rwa selile. Bizagira ingaruka kumikorere ya minisiteri na beto.

3. Kimwe n'amazi menshi, ubwiza bwumuti wa selile ether bizagabanuka hamwe no kwiyongera kwubushyuhe, kandi nubushuhe bwinshi bwa selile ya selile, niko ubushyuhe bugabanuka. Ingaruka nini.

4. Umuti wa selulose ether mubisanzwe ni pseudoplastique, ifite ibiranga kunanuka. Ninshi igipimo cyogosha mugihe cyikizamini, niko umuto muto.

Guhuriza hamwe kwa minisiteri bizagabanuka bitewe nigikorwa cyingufu zo hanze, nacyo kikaba gifasha mukubaka ibisasu bya minisiteri, bikavamo guhuza neza no gukora bya minisiteri icyarimwe. Ariko, niba igisubizo cya selulose ether gifite intumbero yo hejuru Iyo viscosity iba mike kandi ibishishwa bikaba bito, bizerekana ibiranga amazi ya Newtonian. Iyo kwibandaho kwiyongera, igisubizo kizagenda cyerekana buhoro buhoro ibiranga amazi ya pseudoplastique, kandi niba kwibumbira hamwe ari byinshi, pseudoplastique izagaragara cyane.
