Cellulose ether irinda uburyo bwa hydrata ya sima

Cellulose ether ni ubwoko bwa polymer polymer compound ikoreshwa cyane mubikoresho byubaka, cyane cyane mubikoresho bishingiye kuri sima. Cellulose ether irashobora gutinza inzira ya hydrata ya sima, bityo igahindura imikorere, igashyiraho igihe niterambere ryambere rya sima paste.

(1). Gutinda kwa hydration reaction
Ether ya selile irashobora gutinza hydrata reaction ya sima, igerwaho cyane cyane muburyo bukurikira:

1.1 Kwinjira no gukingira ingaruka
Umuti mwinshi wijimye wakozwe no gushonga selile ya ether mumuti wamazi urashobora gukora firime ya adsorption hejuru yubutaka bwa sima. Ishirwaho ryiyi firime ahanini riterwa na adsorption yumubiri wamatsinda ya hydroxyl muri selile ya selile ya ether na ion hejuru yubutaka bwa sima, bikavamo ubuso bwa sima ikingiwe, bikagabanya umubano hagati ya sima na molekile zamazi, bityo gutinza reaction ya hydration.

1.2 Gukora firime
Mubyiciro byambere bya hydrata ya sima, selile ether irashobora gukora firime yuzuye hejuru yubutaka bwa sima. Kuba iyi firime ibaho neza bibuza gukwirakwiza molekile zamazi imbere mubice bya sima, bityo bikadindiza umuvuduko wa hydrata ya sima. Byongeye kandi, ishyirwaho ryiyi firime rishobora kandi kugabanya iseswa nogukwirakwiza ioni ya calcium, bikadindiza ishyirwaho ryibicuruzwa biva mu mazi.

1.3 Gusenyuka no kurekura amazi
Ether ya selile ifite amazi akomeye, irashobora gukuramo ubuhehere no kurekura buhoro. Ubu buryo bwo kurekura amazi burashobora guhindura amazi no gukora bya sima ya sima kurwego runaka, kandi bikagabanya umuvuduko wogutwara amazi mukugabanya ubukana bwamazi mugihe cyamazi.

(2). Ingaruka zicyiciro cya sima
Ether ya selile igira ingaruka zitandukanye kumazi ya sima zitandukanye. Mubisanzwe, selile ether igira ingaruka zigaragara kumazi ya tricalcium silicate (C₃S). Kubaho kwa selulose ether bizadindiza hydrata ya C₃S kandi bigabanye umuvuduko wo kurekura ubushyuhe bwamazi ya C₃S hakiri kare, bityo bidindiza iterambere ryimbaraga hakiri kare. Byongeye kandi, ethers ya selile irashobora kandi kugira ingaruka kumazi yibindi bikoresho byamabuye y'agaciro nka silikatike ya dicalcium (C₂S) na trumincium aluminate (C₃A), ariko izo ngaruka ni nto.

(3). Imiterere n'ingaruka zubaka
Ether ya selile irashobora kongera ubwiza bwa sima kandi ikagira ingaruka kumyumvire yayo. Ubushuhe buhebuje bufasha kugabanya gutuza no gutondekanya ibice bya sima, bigatuma sima ikomeza kugira uburinganire bwiza mbere yo gushiraho. Uku kwiyegereza kwinshi kuranga ntigutinda gusa inzira ya hydrata ya sima gusa, ahubwo binatezimbere ubwiza bwimikorere nubwubatsi bwa sima.

(4). Ingaruka zo gusaba no kwirinda
Ether ya selulose igira ingaruka zikomeye mukurinda hydrata ya sima bityo rero ikoreshwa kenshi muguhindura igihe cyagenwe nubworoherane bwibikoresho bishingiye kuri sima. Nyamara, ingano nubwoko bwa selile ether bigomba kugenzurwa neza, kubera ko ether ya selile ikabije ishobora gutera ibibazo nkimbaraga zidahagije hakiri kare ndetse no kugabanuka kwibikoresho bishingiye kuri sima. Byongeye kandi, ubwoko butandukanye bwa ethers ya selile (nka methylcellulose, hydroxypropylmethylcellulose, nibindi) bifite uburyo butandukanye ningaruka zitandukanye muri sima, kandi bigomba gutoranywa ukurikije ibisabwa byihariye bisabwa.

Ikoreshwa rya selile ya selile mubikoresho bishingiye kuri sima ntibishobora gusa gutinza neza reaction ya hydrata ya sima, ariko kandi binatezimbere imikorere yubwubatsi nigihe kirekire cyibikoresho. Binyuze mu guhitamo neza no gukoresha ethers ya selile, ubwiza nubwubatsi bwibikoresho bishingiye kuri sima birashobora kunozwa cyane.
