Ether ya selile ifite amazi meza cyane, ashobora kubuza ubuhehere buri muri minisiteri itose guhumeka imburagihe cyangwa gutwarwa nigice cyibanze, kandi ikemeza ko sima iba yuzuye neza, bityo bikarangira byemeza imiterere yubukorikori bwa minisiteri, bifite akamaro cyane cyane. Kuri minisiteri yoroheje kandi ifata amazi ibice fatizo Cyangwa minisiteri yubatswe mubushyuhe bwinshi kandi bwumutse.Ingaruka yo gufata amazi ya selulose ether irashobora guhindura inzira yubwubatsi gakondo no kunoza iterambere ryubwubatsi.Kurugero, ubwubatsi bwo guhomesha burashobora gukorwa kumasoko akurura amazi atabanje gutose.
Ubukonje, ibipimo, ubushyuhe bwibidukikije hamwe na molekulire ya selile ya ether bigira uruhare runini mubikorwa byo gufata amazi.Mubihe bimwe, uko ubwinshi bwa selulose ether, niko gufata amazi neza;hejuru ya dosiye, nibyiza kubika amazi.Mubisanzwe, selile nkeya ya selile irashobora kunoza cyane gufata amazi ya minisiteri.Iyo igipimo kigeze kuri runaka Iyo urugero rwo gufata amazi rwiyongereye, inzira yo gufata amazi iratinda;iyo ubushyuhe bwibidukikije buzamutse, kubika amazi ya selile ya selile mubisanzwe bigabanuka, ariko ethers zimwe na zimwe zahinduwe na selile zifite amazi meza mugihe cy'ubushyuhe bwinshi;fibre ifite degere zo hasi zo gusimbuza Vegan ether ifite imikorere myiza yo gufata amazi.
Itsinda rya hydroxyl kuri molekile ya selile ya selile na atome ya ogisijeni ku muyoboro wa ether izahuza na molekile y’amazi kugira ngo ihuze hydrogene, ihindure amazi yubusa mu mazi aboshye, bityo bigire uruhare runini mu gufata amazi;molekile y'amazi hamwe na selulose ether ya molekuline ya Interdiffusion ituma molekile zamazi zinjira mumbere yumunyururu wa selulose ether macromolecular kandi zigakoreshwa nimbaraga zikomeye zihuza, bityo zigakora amazi aboshye hamwe namazi yiziritse, bigatuma amazi agumana neza ya sima;selulose ether itezimbere sima nshya.Imiterere ya rheologiya, imiterere y'urusobekerane rwumuvuduko numuvuduko wa osmotic cyangwa imiterere ya firime ya selulose ether ibuza ikwirakwizwa ryamazi.
Cellulose ether iha minisiteri itose hamwe nubwiza buhebuje, bushobora kongera cyane ubushobozi bwo guhuza hagati ya minisiteri itose nigitereko fatizo, kandi bikanoza imikorere yo kurwanya kugabanuka.Ikoreshwa cyane mugupompa minisiteri, kubumba amatafari hamwe na sisitemu yo gukingira urukuta.Ingaruka yibyibushye ya selile ya selile irashobora kandi kongera ubushobozi bwo kurwanya ikwirakwizwa hamwe nuburinganire bwibikoresho bivanze bishya, bikarinda gusibanganya ibintu, gutandukanya no kuva amaraso, kandi birashobora gukoreshwa muri beto ya fibre, beto yo mumazi na beto yonyine.
Ingaruka yibyibushye ya selile ya ether kubikoresho bishingiye kuri sima biva mubwiza bwumuti wa selile.Mubihe bimwe, niko hejuru ya viscosity ya selulose ether, niko ubwiza bwibintu byahinduwe bishingiye kuri sima, ariko niba ububobere buri hejuru cyane, bizagira ingaruka kumikorere no mumikorere yibikoresho (nko gufatisha icyuma gipompa ).Kwiyubaka-minisiteri no kwikuramo beto, bisaba amazi menshi, bisaba ubukonje buke bwa selile ether.Byongeye kandi, umubyibuho ukabije wa selile ya selile uzamura amazi yibikoresho bishingiye kuri sima kandi byongere umusaruro wa minisiteri.
Ubwiza bwumuti wa selulose ether biterwa nibintu bikurikira: uburemere bwa molekuline ya selile ya selile, kwibanda, ubushyuhe, igipimo cyogukoresha nuburyo bwo gupima.Mubihe bimwe, uburemere bwa molekuline ya selile ya ether, niko ubwiza bwibisubizo;hejuru yibitekerezo, niko viscosity yumuti.Iyo uyikoresheje, ugomba kwitondera kwirinda ibipimo birenze urugero kandi bikagira ingaruka kumikorere ya minisiteri na beto;selulose ether Ubukonje bwumuti wa ether buzagabanuka niyongera ryubushyuhe, kandi nubunini bwinshi, niko ingaruka zubushyuhe ninshi;selulose ether igisubizo mubisanzwe ni pseudoplastique fluid hamwe numutungo wo kogosha, niko igipimo kinini cyogosha mugihe cyibizamini, niko ubukonje buke, bityo rero, guhuriza hamwe kwa minisiteri bizagabanuka bitewe nimbaraga ziva hanze, zifitiye akamaro u gusiba kubaka minisiteri, kugirango minisiteri ibashe gukora neza no guhuriza hamwe icyarimwe;kuberako igisubizo cya selulose ether itari Newtonian Kubisukari, mugihe uburyo bwo kugerageza, ibikoresho nibikoresho cyangwa ibizamini byifashishwa mugupima ububobere butandukanye, ibisubizo byikizamini cya selile imwe ya ether igisubizo bizaba bitandukanye cyane.
Molekile ya selulose irashobora gukosora molekile zimwe zamazi yibintu bishya kuruhande rwurunigi rwa molekile, bityo bikongerera ubwiza bwumuti.Iminyururu ya molekuline ya selulose ether irahujwe kugirango ikore urwego rwibice bitatu, bizanatuma igisubizo cyamazi cyacyo gifite ubwiza bwiza.
Umuvuduko mwinshi wa selileose ether amazi yo mumazi afite thixotropy nyinshi, nayo nikintu gikomeye kiranga selile ether.Ibisubizo byamazi ya methyl selulose mubisanzwe bifite pseudoplastique na non-thixotropic fluid munsi yubushyuhe bwa gel, ariko ikerekana imiterere ya Newtonian ku gipimo gito.Pseudoplastique yiyongera hamwe nuburemere bwa molekuline cyangwa kwibumbira hamwe kwa selile ya ether, hatitawe ku bwoko bwinsimburangingo no kurwego rwo gusimburwa.Kubwibyo, selile ya ethers yo murwego rumwe rwubwiza, ntakibazo mc, HPmc, HEmc, izahora yerekana imiterere imwe ya rheologiya mugihe cyose ubushyuhe nubushyuhe bihoraho.Gele yubaka ikorwa mugihe ubushyuhe buzamutse, kandi tixotropique itemba cyane.Ubushuhe bwinshi hamwe na viscosity selileulose ethers yerekana thixotropy no munsi yubushyuhe bwa gel.Uyu mutungo ufite inyungu nyinshi muguhindura kuringaniza no kugabanuka mukubaka inyubako ya minisiteri.Hagomba gusobanurwa hano ko uko ubukonje bwa ether ya selulose, niko gufata amazi neza, ariko uko ubukonje bugenda bwiyongera, niko uburemere bwa molekuline bugereranije na selile ya selile, hamwe no kugabanuka gukwiranye kwayo, bigira ingaruka mbi kuri concentration ya minisiteri nibikorwa byubwubatsi.Iyo hejuru ya viscosity, niko bigaragara ingaruka zo kubyimba kuri minisiteri, ariko ntabwo ihwanye rwose.Bimwe mubiciriritse kandi bito, ariko selile yahinduwe ya selile ifite imikorere myiza mugutezimbere imbaraga zimiterere ya minisiteri itose.Hamwe no kwiyongera kwijimye, kugumana amazi ya selile ether biratera imbere.
