Imikorere ya selulose ether muri minisiteri ni: kubika amazi, kongera ubumwe, kubyimba, bigira ingaruka kumwanya, hamwe nibintu byinjira mu kirere.Kubera ibyo biranga, ifite umwanya munini wo gukoresha mukubaka ibikoresho bya minisiteri.
1. Kugumana amazi ya selile ya selile nicyo kintu cyingenzi kiranga ikoreshwa rya minisiteri.
Impamvu nyamukuru zigira ingaruka kumazi ya selulose ether: viscosity, ingano yuduce, dosiye, ingirakamaro, igipimo cyo gusesa, uburyo bwo gufata amazi: kubika amazi ya selile ya selile ubwayo bituruka kumashanyarazi no kubura umwuma wa selile ubwayo.Nubwo urunigi rwa selile ya selile irimo umubare munini wamatsinda ya hydroxyl afite hydrata ikomeye, ntabwo ishonga mumazi.Ni ukubera ko selile ya selile ifite urwego rwo hejuru rwa kristu, kandi ubushobozi bwo kuyobora amatsinda ya hydroxyl yonyine ntibihagije kugirango bisenye imiyoboro ikomeye.Amazi ya hydrogène hamwe na van der Waals imbaraga, bityo irabyimba gusa ariko ntishonga mumazi.Iyo insimburangingo yinjijwe mumurongo wa molekile, ntabwo insimburangingo gusa isenya umugozi wa hydrogène, ariko kandi imigozi ya hydrogène ihuza imiyoboro iracika kubera guhuza ibice hagati yiminyururu yegeranye.Ninini isimbuye, nini intera iri hagati ya molekile, isenya ingaruka ya hydrogène.Ninini ya selile ya selile, igisubizo cyinjira nyuma ya selile ya selile imaze kwaguka, na ether ya selile ihinduka amazi, igashiraho igisubizo cyinshi-cyinshi.Iyo ubushyuhe buzamutse, hydrated ya polymer igabanuka, kandi amazi ari hagati yiminyururu yirukanwa.Iyo umwuma uhagije, molekile zitangira kwegeranya, zigakora imiterere-yimiyoboro itatu-yimiterere nubushyuhe bwa gel.
(1) Ingaruka yubunini bwibice no kuvanga igihe cya selile ya ether mukubika amazi
Hamwe na selile ingana na selile, kubika amazi ya minisiteri byiyongera hamwe no kwiyongera kwijimye;kwiyongera k'ubunini bwa selile ether no kwiyongera kwijimye byongera amazi ya minisiteri.Iyo ibikubiye muri selile ya selile irenze 0.3%, ihinduka ryamazi yo gufata minisiteri ikunda kuringanizwa.Ubushobozi bwo gufata amazi ya minisiteri bugenzurwa ahanini nigihe cyo gusesa, kandi ether nziza ya selile nziza irashonga vuba, kandi ubushobozi bwo gufata amazi bukura vuba.
)
Mugihe ubushyuhe buzamutse, gufata amazi biragabanuka, kandi uko urwego rwo hejuru rwa etherifike ya selile ya selile, niko amazi meza agumana ubushyuhe bwa selile.Mugihe cyo gukoresha, ubushyuhe bwa minisiteri ivanze nubusanzwe buri munsi ya 35 ° C, kandi mugihe cyikirere kidasanzwe, ubushyuhe bushobora kugera cyangwa kurenga 40 ° C.Muri iki kibazo, formula igomba guhinduka kandi ibicuruzwa bifite urwego rwo hejuru rwa etherification bigomba guhitamo.Nukuvuga, tekereza guhitamo selile ikwiye.
2. Ingaruka ya selulose ether kumyuka ya minisiteri
Mu bicuruzwa byumye bivanze na minisiteri, bitewe no kongeramo ether ya selile, umubare munini wuduce duto, twagabanijwe kimwe kandi duhumeka ikirere twinjiza mumashanyarazi mashya avanze.Bitewe numupira wumupira wibibyimba byumwuka, minisiteri ifite imikorere myiza kandi igabanya torsion ya minisiteri.Kumena no kugabanuka, no kongera umusaruro wa minisiteri.
3. Ingaruka ya selile ya ether kuri hydrata ya sima
Ether ya selile ifite ubushobozi bwo kudindiza hydrata ishingiye kuri sima, kandi ingaruka zo kudindiza ziyongera hamwe no kwiyongera kwa selile.Ibintu bigira ingaruka kuri selile ya ether kuri hydrata ya sima ni: dosiye, urugero rwa etherification, ubwoko bwa sima.
