Muri minisiteri yumye, selulose ether ninyongeramusaruro nyamukuru ishobora kunoza cyane imikorere ya minisiteri itose kandi ikagira ingaruka kumyubakire ya minisiteri. Methyl selulose ether igira uruhare mukubungabunga amazi, kubyimba, no kunoza imikorere yubwubatsi. Imikorere myiza yo gufata neza amazi iremeza ko minisiteri itazatera umucanga, ifu no kugabanuka kwingufu kubera kubura amazi hamwe n’amazi meza ya sima atuzuye; Ingaruka yibyimbaraga Imbaraga zububiko bwa minisiteri yatose ziyongereye cyane, kandi hiyongereyeho methyl selulose ether irashobora kuzamura cyane ububobere bwamazi ya minisiteri itose, kandi ikagira neza neza kubutaka butandukanye, bityo bikazamura imikorere ya minisiteri itose kurukuta. no kugabanya imyanda; mubyongeyeho, bitandukanye Uruhare rwa selile mubicuruzwa nabyo biratandukanye, kurugero: selile mumatafari ya tile irashobora kongera igihe cyo gufungura no guhindura igihe; selile mu mashini yo gutera imashini irashobora kuzamura imbaraga zimiterere ya minisiteri itose; murwego rwo kwishyira ukizana, selile igira uruhare mukurinda gutura, Gutandukanya no gutondeka.
Umusaruro wa selile ya selile ukorwa cyane cyane mumibiri karemano binyuze mumashanyarazi ya alkali, reaction reaction (etherification), gukaraba, kumisha, gusya nibindi bikorwa. Ibikoresho nyamukuru byibanze bya fibre karemano birashobora kugabanywamo: fibre yipamba, fibre cederi, fibre ya beech, nibindi. Urwego rwabo rwa polymerisation ruratandukanye, bizagira ingaruka kumyuka yanyuma yibicuruzwa byabo. Kugeza ubu, inganda zikomeye za selile zikoresha fibre (ibikomoka kuri nitrocellulose) nkibikoresho nyamukuru. Ether ya selile irashobora kugabanywamo ionic na non-ionic. Ubwoko bwa ionic burimo ahanini umunyu wa carboxymethyl selulose, naho ubwoko butari ionic burimo methyl selulose, methyl hydroxyethyl (propyl) selile, na hydroxyethyl selulose. Su n'ibindi. Mu ifu yumye yumye, kubera ko ionic selulose (umunyu wa carboxymethyl selulose) idahindagurika imbere ya calcium ion, ntabwo ikoreshwa gake mubicuruzwa byifu byumye nka sima yatoboye lime nkibikoresho bya sima.
Kugumana amazi ya selile nabyo bifitanye isano n'ubushyuhe bwakoreshejwe. Kugumana amazi ya methyl selulose ether bigabanuka hamwe no kwiyongera kwubushyuhe. Kurugero, mugihe cyizuba, iyo hari urumuri rwizuba, urukuta rwo hanze rushyizweho plaque, akenshi byihutisha gukira kwa sima na minisiteri. Gukomera no kugabanuka kw'igipimo cyo gufata amazi biganisha ku kumva neza ko imikorere y'ubwubatsi ndetse n'imikorere yo kurwanya ibice. Kuri iki kibazo, ni ngombwa cyane kugabanya ingaruka ziterwa nubushyuhe. Rimwe na rimwe, ntishobora guhaza ibikenewe gukoreshwa. Bumwe mu buvuzi bukorerwa kuri selile, nko kongera urugero rwa etherification, nibindi, kugirango ingaruka zo gufata amazi zirashobora gukomeza kugira ingaruka nziza kubushyuhe bwo hejuru.
Kugumana amazi ya selile: Ibintu nyamukuru bigira ingaruka ku gufata amazi ya minisiteri harimo ingano ya selile yongeweho, ubwiza bwa selile, ubwiza bwa selile, hamwe nubushyuhe bwibidukikije bikora.
Ubusembwa bwa selile: Muri rusange, uko ubukonje buri hejuru, niko bigira ingaruka nziza yo gufata amazi, ariko uko ubukonje bugenda bwiyongera, uburemere bwa molekuline ya selile, hamwe no kugabanuka gukwiranye kwayo, bigira ingaruka mbi mubikorwa byubwubatsi. n'imbaraga za minisiteri. Iyo hejuru yubukonje, niko bigaragara ingaruka zo kubyimba kuri minisiteri, ariko ntabwo ihwanye neza. Iyo hejuru yubukonje, niko amabuye atose azaba menshi. Mugihe cyubwubatsi, izakomeza kumashanyarazi kandi ifatanye cyane na substrate, ariko ntabwo bizafasha cyane kongera imbaraga zimiterere ya minisiteri itose ubwayo, kandi imikorere yo kurwanya sag ntizagaragara mugihe cyo kubaka.
Ubwiza bwa selile: Ubwiza bugira ingaruka kumikorere ya selile ether. Cellulose ya selile isanzwe ni granular kandi ikwirakwizwa byoroshye mumazi nta agglomeration, ariko igipimo cyo gusesa kiratinda cyane. Ntibikwiye gukoreshwa mumashanyarazi yumye. Imbere mu gihugu Bimwe muri selile ni flocculent, ntabwo byoroshye gutatanya no gushonga mumazi, kandi biroroshye guhuriza hamwe. Ifu nziza gusa irashobora kwirinda methyl selulose ether agglomeration mugihe wongeyeho amazi no gukurura. Ariko selelose yuzuye ether ntabwo isesagura gusa ahubwo inagabanya imbaraga zaho za minisiteri. Iyo ifu yumye yumye yubatswe ahantu hanini, umuvuduko wo gukiza wa minisiteri yaho biragaragara ko wagabanutse, kandi gucamo bitewe nibihe bitandukanye byo gukira bigaragara. Bitewe nigihe gito cyo kuvanga, minisiteri nubwubatsi bwa mashini bisaba ubwiza buhebuje.
