Cellulose ether nibikoresho byingenzi bya polymer bikoreshwa cyane mubikoresho byubwubatsi, ubuvuzi, ibiryo nibindi bice. Umutungo wacyo wo kubika amazi nimwe mubintu byingenzi bigira uruhare mubikorwa byinshi. Imikorere yo gufata amazi igira ingaruka itaziguye yo gufatana, guhindagurika no kubaka ibikoresho. Urwego rwa etherification hamwe nubushyuhe bwa selulose ether nibintu bibiri byingenzi bigira ingaruka kumazi.
Ingaruka ya etherification ya selulose ether mukubika amazi
Ethers ya selile ikorwa muguhindura hydroxyl igice cya selile mumatsinda ya ether. Urwego rwa etherification bivuga umubare wamatsinda ya ether yatangijwe kuri buri gice cya glucose, ikoreshwa mugupima urugero rwo gusimbuza ether selile. Urwego rwa etherification rufite ingaruka zikomeye ku kugumana amazi ya selile ya selile. Muri rusange, uko urwego rwa etherification rwiyongera, hydrophilicity ya selulose ether iriyongera, kandi imikorere yayo yo gufata amazi nayo iriyongera.
Urwego rwohejuru rwa etherification, niko amatsinda ya hydrophilique (nka mikorerexy, ethoxy, nibindi) yinjiye mumurongo wa selile ya ether. Aya matsinda arashobora gukorana na molekile yamazi binyuze mumigozi ya hydrogène, igashimangira selile Yubushobozi bwa adsorption ya ether kuri molekile zamazi. Kubwibyo, selile ya selile ifite impamyabumenyi ihanitse irashobora gukurura no kugumana amazi menshi mubidukikije, bigatuma iba nziza muburyo bwo gufata amazi.
Ariko, urwego rwo hejuru rwa etherification, nibyiza. Iyo urugero rwa etherification rugeze kurwego runaka, kugumana amazi ya selile ya selile ntishobora gukomeza kwiyongera hamwe no kwiyongera kurwego rwa etherification, ndetse irashobora no kugabanuka. Ibi ni ukubera ko iyo etherification ari ndende cyane, imiterere yumurongo wa selile ya selile ya selile irashobora guhinduka, bikaviramo intege nke zingirakamaro, amaherezo bikagira ingaruka kumazi no kubika amazi. Kubwibyo, mubikorwa bifatika, selulose ethers ifite impamyabumenyi ikwiye ya etherification igomba guhitamo ukurikije ibihe byihariye.
Ingaruka yubushyuhe ku kubika amazi ya selile
Ubushyuhe ni ikindi kintu kigira uruhare runini mu gufata amazi ya selile ya selile. Mubihe byubushyuhe butandukanye, imiterere yo gufata amazi ya selile ethers yitwara ukundi. Mubisanzwe, kwiyongera kwubushyuhe bizatuma kugabanuka kwamazi ya selile ya selile. Ibi biterwa ahanini nuko izamuka ryubushyuhe ryihuta ryuka ryamazi, bigatuma ibikoresho bigumana ubushuhe.
Ku bushyuhe bwo hasi, imikoranire hagati ya molekile ya selile na molekile y'amazi irakomeye, bigatuma amazi meza agumana. Mugihe ubushyuhe bwiyongereye, molekile zamazi zishira vuba, kandi ubushobozi bwo gufata amazi ya selile ether buhoro buhoro. Byongeye kandi, ubushyuhe bwiyongereye bushobora kugira ingaruka kuri solubose ethers. Mubihe bimwe byubushyuhe bwo hejuru, selile ether irashobora gutakaza imbaraga kandi ikananirwa gukora igisubizo kimwe cyangwa colloid, bityo bikagira ingaruka kumikorere yabyo.
Birakwiye ko tumenya ko ubwoko butandukanye bwa selulose ethers ifite sensitivité zitandukanye kumihindagurikire yubushyuhe. Ethers zimwe na zimwe za selile zirashobora gukomeza gufata neza amazi mubushyuhe bwinshi, mugihe izindi zizagabanuka cyane kubika amazi mugihe ubushyuhe buzamutse gato. Kubwibyo, mugihe uhisemo selile ether, birakenewe guhitamo neza ukurikije imiterere yubushyuhe bwibidukikije.
Imikoranire hagati yurwego rwa etherification nubushyuhe
Ingaruka za dogere ya etherification hamwe nubushyuhe ku kugumana amazi ya selile ether akenshi usanga bikorana. Mubikorwa bifatika, ibi bintu byombi bikenera gusuzumwa byuzuye. Kurugero, mugihe selile ya selile ifite urwego rwohejuru rwa etherification ikoreshwa mubushuhe bwo hejuru, naho urugero rwinshi rwa etherification rushobora kuzamura amazi ya selile ya selile, umuvuduko wamazi mumazi yubushyuhe bwo hejuru nayo azoba byihuse bikwiranye, bityo bigabanya ingaruka zifatika zo gufata amazi. Kubwibyo, mubushyuhe bwo hejuru cyane, birashobora kuba nkenerwa gukoresha ether ya selile ifite ibikoresho byahinduwe byumwihariko kugirango barusheho guhangana nubushyuhe bwo hejuru no kubika amazi.
Ibinyuranye, mubushyuhe buke, ingaruka za etherification kurwego rwo kugumana amazi ya selile ya selile irashobora kugaragara cyane. Mugihe cy'ubushyuhe buke, amazi azimuka gahoro gahoro, na ether ya selile ifite urugero rwinshi rwa etherifisiyasi irashobora gukoresha neza ubushobozi bwayo bwo gufata amazi, bityo bigatuma imikorere yibitseho amazi.
Urwego rwa etherification nubushyuhe bwa selile ether nibintu byingenzi bigira ingaruka kumikorere yabyo. Urwego rwohejuru rwa etherification, niko hydrophilicity ya selulose ether ikomera kandi nuburyo bwiza bwo gufata amazi. Nyamara, urwego rwo hejuru cyane rwa etherification rushobora gutuma habaho impinduka mumiterere ya molekile, bityo bikagira ingaruka kumazi. Kuzamuka k'ubushyuhe mubisanzwe biganisha ku kugabanuka kw'amazi ya selile ya selile. By'umwihariko ahantu h’ubushyuhe bwo hejuru, guhumeka amazi byihuta, bigira ingaruka ku gufata amazi. Mubikorwa bifatika, birakenewe guhitamo selulose ether hamwe nurwego rukwiye rwa etherifike hashingiwe kumiterere yubushyuhe bwihariye nibisabwa kugirango ugere kumazi meza yo gufata amazi.
