Ingaruka yibyibushye ya selile

Cellulose etheriha minisiteri itose hamwe nubwiza buhebuje, irashobora kongera cyane ubushobozi bwo guhuza ibishishwa bitose hamwe na nyakatsi, kunoza imikorere ya anti-sag ya minisiteri, ikoreshwa cyane mumashanyarazi, sisitemu yo kubitsa hanze hamwe na matafari yo guhuza amatafari.Ingaruka yibyibushye ya selile irashobora kandi kongera ubushobozi hamwe no kurwanya-gukwirakwiza ibikoresho bishya bishingiye kuri sima, kugirango birinde gutondeka, gutandukanya no kuva amaraso ya minisiteri na beto, birashobora gukoreshwa muri beto ya fibre, beto yo mumazi no kwikorera beto.

Cellulose etherbyongera ubwiza bwibikoresho bishingiye kuri sima biva mubwiza bwa selulose ether igisubizo.Mubisanzwe ukoreshe "viscosity" iki gipimo kugirango usuzume selile ya ether igisubizo cya viscosity, viscosity ya selulose ether muri rusange yerekeza kumurongo runaka (2%) yumuti wa selile ya selile, ubushyuhe (20 ℃) ​​nigipimo cyogosha (cyangwa umuvuduko ukabije, nka 20 RPM) imiterere, hamwe ningingo zigikoresho cyo gupima, nko kuzunguruka viscometer yapimye indangagaciro.Viscosity ni ikintu cyingenzi cyo gusuzuma imikorere ya selile ya selile na selile ya selile, niko hejuru yubusembwa bwibisubizo, niko ubwiza bwibintu fatizo bya sima, ubwiza bwibikoresho fatizo bushobora, kwihanganira sag no kurwanya imbaraga zikomeye zo gukwirakwiza, ariko niba ibishishwa ari binini cyane, birashobora kugira ingaruka kumasima yibanze ya sima no kugendagenda neza (nko kubaka plaster marom adhesive plaster).Kubwibyo, ubwiza bwa selile ya selile ikoreshwa muri minisiteri ivanze yumye mubisanzwe ni 15,000 ~ 60.000 Mpa.s-1, hamwe nubwiza bwa selulose ether birasabwa kuba munsi ya minisiteri yo kwisuzumisha hamwe na compactconcrete hamwe nibisabwa byamazi menshi.Byongeye kandi, kwiyongera kwingirabuzimafatizo ya selile bizongera amazi asabwa mubikoresho bishingiye kuri sima, bityo byongere umusaruro wa minisiteri.Ubukonje bwumuti wa selulose ether biterwa nuburemere bwa molekile (cyangwa urwego rwa polymerisation) hamwe nubushuhe bwa selile ya selile, ubushyuhe bwumuti, igipimo cyogosha, nuburyo bwo gupima.Urwego rwo hejuru rwa polymerisation ya selile ya ether, niko uburemere bwa molekile, niko ubwiza bwumuti wabwo wamazi;Iyo dosiye (cyangwa concentration) ya selulose ether, niko ubwinshi bwibisubizo byumuti wamazi wabwo, ariko mugukoresha bigomba kwitondera guhitamo dosiye ikwiye, kugirango bitavangwa cyane, bigira ingaruka kumikorere ya minisiteri na beto;Kimwe n'amazi menshi, ubwiza bwumuti wa selulose ether bizagabanuka hamwe nubushyuhe bwubushyuhe, kandi nubushuhe bwa selile ya selile, niko ingaruka zubushyuhe ninshi;Cellulose ether igisubizo mubisanzwe numubiri wa pseudoplastique hamwe numutungo wogosha.Kurenza igipimo cyogosha, niko kugabanuka kwijimye.

Kubwibyo, guhuriza hamwe kwa minisiteri bizagabanywa nimbaraga zo hanze, zifasha kubaka ibisasu bya minisiteri, gukora minisiteri bishobora kugira imikorere myiza no guhuriza hamwe.Nyamara, selile ya ether igisubizo kizerekana ibiranga amazi ya Newtonian mugihe intumbero iba mike cyane kandi viscosity ni nto cyane.Iyo kwibandaho kwiyongera, igisubizo kigenda kigaragaza buhoro buhoro ibiranga amazi ya pseudoplastique, kandi nubunini bwinshi, niko bigaragara pseudoplastique.
