Ingaruka yibyibushye ya selulose ether biterwa na: urugero rwa polymerisation ya selile ya selile, kwibanda kumuti, igipimo cyogosha, ubushyuhe nibindi bihe. Umutungo wa gelling wigisubizo numutungo wa alkyl selulose nibiyikomokaho. Imiterere ya gelation ifitanye isano nurwego rwo gusimbuza, kwibanda kubisubizo hamwe ninyongera. Kuri hydroxyalkyl yahinduwe ikomokaho, imiterere ya gel nayo ifitanye isano nimpinduka ya hydroxyalkyl. Kubijyanye n'ubukonje buke MC na HPMC, hashobora gutegurwa 10% -15% igisubizo, ubukonje buciriritse MC na HPMC burashobora gutegurwa igisubizo cya 5% -10%, mugihe ubukonje bwinshi MC na HPMC bushobora gutegura igisubizo 2% -3% gusa, kandi Mubisanzwe ibyiciro bya viscosity ya selulose ether nayo igabanywa na 1% -2% igisubizo.
Uburemere buke bwa selile selile ether ifite ubushobozi bwo kubyimba cyane. Mubisubizo bimwe byo kwibandaho, polymers ifite uburemere butandukanye bwa molekile ifite viscosities zitandukanye. Urwego rwo hejuru. Intego yo kwiyegereza irashobora kugerwaho gusa wongeyeho umubare munini wuburemere buke bwa selile selile. Ubukonje bwabwo ntaho butaniye nigipimo cyogosha, kandi ubukonje bwinshi bugera ku ntego yo kwiyegereza, kandi amafaranga asabwa yongeweho ni make, kandi ubwiza buterwa no kubyimba neza. Kubwibyo, kugirango ugere kumurongo runaka, umubare munini wa selile ya ether (kwibanda kumuti) hamwe nubwiza bwibisubizo bigomba gukemurwa. Ubushyuhe bwa gel bwumuti nabwo bugabanuka kumurongo hamwe no kwiyongera kwumuti wibisubizo, hamwe na geles mubushyuhe bwicyumba nyuma yo kugera kumurongo runaka. Ubunini bwa HPMC buri hejuru cyane mubushyuhe bwicyumba.
Guhuzagurika birashobora kandi guhinduka muguhitamo ingano yingingo no guhitamo selile ya selile hamwe nimpamyabumenyi zitandukanye. Ibyo bita guhindura ni ukumenyekanisha urwego runaka rwo gusimbuza hydroxyalkyl matsinda kumiterere ya skeleton ya MC. Muguhindura indangagaciro yo gusimbuza indangagaciro zibiri zasimbuwe, ni ukuvuga, DS na ms ugereranije no gusimbuza indangagaciro za methoxy na hydroxyalkyl amatsinda dukunze kuvuga. Ibikorwa bitandukanye bisabwa bya selile ether birashobora kuboneka muguhindura agaciro kagereranijwe gusimbuza ibintu byombi.
Isano iri hagati yo guhuzagurika no guhinduka: kongeramo ether ya selile bigira ingaruka kumikoreshereze yamazi ya minisiteri, guhindura igipimo cyamazi gihuza amazi na sima ningaruka zibyibushye, uko dosiye ikabije, niko gukoresha amazi menshi.
Ether ya selile ikoreshwa mubikoresho byubwubatsi bigomba gushonga vuba mumazi akonje kandi bigatanga uburyo bukwiye kuri sisitemu. Niba uhaye igipimo runaka cyogosha, iracyahinduka flocculent na colloidal block, nigicuruzwa kitujuje ubuziranenge cyangwa cyiza.
Hariho kandi umurongo mwiza uhuza umurongo hagati ya sima paste na dosiye ya selile ether. Cellulose ether irashobora kongera cyane ubwiza bwa minisiteri. Ninini nini, niko bigaragara ingaruka. Umuvuduko mwinshi wa selileose ether amazi yo mumazi afite thixotropy nyinshi, nayo nikintu gikomeye kiranga selile ether. Ibisubizo byamazi ya polymers ya MC mubisanzwe bifite pseudoplastique na non-thixotropic fluidity munsi yubushyuhe bwa gel, ariko imitungo ya Newtonian itemba mukigero 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 ether 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 selile nkeya ya selile yerekana thixotropy ndetse no munsi yubushyuhe bwa gel. Uyu mutungo ufite akamaro kanini 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.
