Ingaruka ya selile ya ether kuri hydrata ya sima

Ether ya selile ni ubwoko bwimiterere ya polymer organic yahinduwe muburyo bwa selile. Bakunze gukoreshwa mubikoresho byo kubaka, cyane cyane mubikoresho bishingiye kuri sima. Ingaruka ya selile ya ether kuri gahunda ya hydrata ya sima igaragarira cyane cyane mubice bikurikira: gukwirakwiza uduce twa sima, gufata amazi, ingaruka zibyibushye, hamwe ningaruka kuri morphologie no guteza imbere imbaraga ziva muri sima.

1. Intangiriro yo gufata amazi ya sima
Uburyo bwa hydrata ya sima nuruhererekane rwibintu bigoye byumubiri na chimique hagati ya sima namazi. Izi reaction zitera paste ya sima gukomera buhoro buhoro kugirango ibe imiterere ihamye, amaherezo itanga ibicuruzwa biva mumazi nka calcium silicate hydrate (CSH) na hydroxide ya calcium (CH). Muri iki gikorwa, igipimo cyamazi ya sima, amazi no kugumana amazi ya slurry, hamwe no gukora ibicuruzwa biva mumazi bigira ingaruka kuburyo butaziguye imbaraga nigihe kirekire cya beto yanyuma.

2. Uburyo bwibikorwa bya selile ethers
Cellulose ether igira uruhare runini rwo kugenzura imikorere ya sima. Ether ya selulose igira ingaruka cyane cyane kubikorwa bya hydrata ya sima muburyo bubiri: imwe ni muguhindura ikwirakwizwa ryuka ryamazi mumazi ya sima; ikindi ni mukugira ingaruka ku gutatanya no gukwirakwiza uduce twa sima.

Kugenzura ubuhehere no gufata amazi
Ethers ya selile irashobora kunoza cyane kubika amazi yibikoresho bishingiye kuri sima. Bitewe na hydrophilicity ikomeye, selile ether irashobora gukora igisubizo gihamye cya colloidal mumazi, gishobora gukurura no kugumana ubuhehere. Ubu bushobozi bwo gufata amazi ni ngombwa mu kugabanya ibice biterwa no gutakaza amazi byihuse muri beto mugihe cyo gutangira hakiri kare. By'umwihariko ahantu humye cyangwa ahantu h'ubushyuhe bwo hejuru, ether ya selile irashobora kubuza neza amazi guhumeka vuba kandi ikemeza ko amazi menshi mumashanyarazi ya sima arahagije kugirango ashyigikire bisanzwe.

Rheology and Thickening
Ether ya selile irashobora kandi kunoza rheologiya ya sima. Nyuma yo kongeramo selile ether, ubudahwema bwa sima biziyongera cyane. Iyi phenomenon ahanini iterwa nimiterere miremire ikorwa na molekile ya selile ya selile. Iyi molekile miremire irashobora kugabanya urujya n'uruza rwa sima, bityo bikongerera ubwiza no guhora kwa slurry. Uyu mutungo ni ingenzi cyane mubisabwa nko guhomesha no gufatisha amatafari, kuko birinda minisiteri ya sima gutemba vuba mugihe itanga imikorere myiza yubwubatsi.

Gutinda hydration no guhindura igihe cyo gushiraho
Cellulose ether irashobora gutinza hydrata reaction ya sima kandi ikongera igenamigambi ryambere nigihe cyanyuma cyo gushiraho sima. Izi ngaruka zibaho kubera ko molekile ya selile ya selile yamamaye hejuru yubutaka bwa sima, bigakora inzitizi ibuza guhura hagati yamazi na sima, bityo bikadindiza reaction. Mugutinda kugena igihe, ethers ya selile irashobora kunoza imikorere yubwubatsi, igaha abakozi bubaka umwanya munini wo guhindura no gukosora.

3. Ingaruka kumiterere yibicuruzwa bitanga amazi
Kubaho kwa selile ya selile nabyo bigira ingaruka kuri microstructure yibicuruzwa bitanga amazi. Ubushakashatsi bwerekanye ko morphologie ya calcium silicate hydrate (CSH) gel izahinduka nyuma yo kongeramo selile. Molekile ya selile irashobora kugira ingaruka kumiterere ya kristu ya CSH, bigatuma irekura. Iyi miterere irekuye irashobora kugabanya imbaraga hakiri kare kurwego runaka, ariko kandi ifasha kunoza ubukana bwibintu.

Ether ya selulose irashobora kandi kugabanya imiterere ya ettringite mugihe cya hydration. Kubera ko selile ether idindiza igipimo cya hydration reaction, umuvuduko wa ettringite muri sima uragabanuka, bityo bikagabanya imihangayiko yimbere iterwa no kwaguka kwijwi mugihe cyo gukira.

4. Ingaruka ku iterambere ryimbaraga
Ethers ya selile nayo igira ingaruka zikomeye kumajyambere yiterambere ryibikoresho bishingiye kuri sima. Kuberako selile ya selile idindiza igipimo cya hydrata ya sima, iterambere ryambere ryimyanya ya sima mubusanzwe ritinda. Nyamara, uko reaction ya hydration ikomeza, ingaruka zo kugenzura amazi ya selulose ether no gufata neza hydrata ya morphologie irashobora kugaragara buhoro buhoro, bizafasha kuzamura imbaraga mubyiciro bizakurikiraho.

Twabibutsa ko umubare wongeyeho nubwoko bwa selile ether bigira ingaruka ebyiri kumbaraga. Umubare ukwiye wa selulose ether urashobora kunoza imikorere yubwubatsi no kongera imbaraga nyuma, ariko gukoresha cyane birashobora gutuma igabanuka ryimbaraga za mbere yibikoresho bishingiye kuri sima kandi bikagira ingaruka kumiterere yanyuma yubukanishi. Kubwibyo, mubikorwa bifatika, ubwoko na dosiye ya selile ether bigomba kuba byiza kandi bigakorwa ukurikije ibisabwa byubuhanga.

Ether ya selulose igira ingaruka kumikorere ya hydrata nibintu bya sima mugutezimbere amazi yibikoresho bishingiye kuri sima, guhindura igipimo cyamazi, kandi bigira ingaruka kumiterere yibicuruzwa. Nubwo selile ya selile ishobora gutera imbaraga zo hakiri kare, zirashobora kunoza kuramba no gukomera kwa beto mugihe kirekire. Kwiyongera kwa selulose ether birashobora kandi kunoza imikorere yubwubatsi, cyane cyane mubikorwa bisaba igihe kirekire cyakazi hamwe nibisabwa byo gufata amazi menshi. Ifite ibyiza bidasubirwaho. Mubikorwa byubwubatsi nyabyo, guhitamo neza ubwoko na dosiye ya selile ya ether irashobora kuringaniza imbaraga, imikorere yubwubatsi nibisabwa biramba byibikoresho.
