Cellulose Ether- Kubyimba hamwe na Thixotropy
Cellulose etheritanga minisiteri itose hamwe nubwiza buhebuje, bushobora kongera cyane gufatana hagati yubutaka butose nigitereko fatizo, kunoza imikorere yo kurwanya imigozi ya minisiteri, kandi bikoreshwa cyane muguhomesha minisiteri, ceramic tile ihuza minisiteri, hamwe na sisitemu yo gukingira urukuta hanze.Ingaruka yibyibushye ya selile irashobora kandi kongera ubushobozi bwo kurwanya ikwirakwizwa hamwe nuburinganire bwibikoresho bishya, kandi bikarinda gutondekanya ibintu, gutandukana, hamwe n’amazi.Irashobora gukoreshwa kuri fibre ikozwe neza, beto yo mumazi, hamwe na beto yonyine.
Ingaruka yo kubyimba yaselile etherku bikoresho bishingiye kuri sima biva mubwiza bwa selile ether igisubizo.Mubihe bimwe, hejuru ya viscosity yaselile ether, nibyiza ubwiza bwibikoresho byahinduwe na sima.Ariko, niba ibishishwa biri hejuru cyane, bizagira ingaruka kumikorere no mumikorere yibikoresho (nko guhomesha ibyuma).Kwiyoroshya kwa minisiteri, kwikuramo beto, nibindi bisaba amazi menshi, kandi ubwiza bwa selile ether ni buke cyane.Byongeye kandi, umubyibuho ukabije wa selulose ether uzanongerera amazi amazi ya sima kandi yongere umusaruro wa minisiteri.
Igisubizo cyamazi ya viscosity selulose ether ifite thixotropy nyinshi, nayo iranga selile ether.Igisubizo cyamazi ya methyl selulose mubusanzwe gifite pseudoplastique na non thixotropique itemba munsi yubushyuhe bwa gel, ariko ikerekana imigezi ya Newtonian ku gipimo gito.Hatitawe ku bwoko n'urwego rwo gusimbuza insimburangingo, pseudoplastique yiyongera hamwe no kwiyongera k'uburemere bwa molekile cyangwa kwibumbira hamwe kwa selile.Kubwibyo, mugihe cyose ubushyuhe nubushyuhe biguma bihoraho, selile ya selile hamwe nicyiciro kimwe cyubwiza (tutitaye kuri MC,HPMC, HEMC) burigihe kwerekana imiterere imwe ya rheologiya.Iyo ubushyuhe buzamutse, imiterere ya gel yubatswe hamwe na thixotropique itemba ibaho.
Cellulose etherababikora bakubwira ko ether ya selile ifite ubukana bwinshi hamwe nubukonje buke ifite thixotropy ndetse no mubushyuhe bwa gel.Uyu mutungo ni ingirakamaro cyane mubwubatsi bwa minisiteri kugirango uhindure urwego no kugabanuka.Twabibutsa ko hejuru ya viscosity yaselile ether, ibyiza byo gufata amazi.Nyamara, uko hejuru yubukonje, niko uburemere bugereranije uburemere bwa selile ya ether, hamwe no kugabanuka gukwiranye kwayo.Ifite ingaruka mbi kumitekerereze no gutunganya minisiteri.
Cellulose Ether- Gutinda
Cellulose etherIrashobora kongera igihe cyagenwe cya sima cyangwa minisiteri, gutinza hydrated kinetics ya sima, kandi igateza imbere ubuzima bwa serivisi bwibikoresho bishya, bityo bikazamura ubudahangarwa bwo gusinzira hagati ya minisiteri na beto.Urwego rwigihombo mugihe, ariko birashobora no kudindiza iterambere ryubwubatsi.
