Gukoresha Cellulose Ether

Mubigize ifu yumye yumye,selile etherni inyongera yingirakamaro hamwe nubunini bwiyongereye ugereranije, ariko irashobora kunoza cyane kuvanga no kubaka imikorere ya minisiteri. Tubivuze mu buryo bworoshe, hafi ya byose bivanga amazi ya minisiteri ishobora kugaragara nijisho ryonyine bitangwa na selile ya ether. Nibikomoka kuri selile yabonetse ukoresheje selulose iva mubiti na pamba, ikorana na soda ya caustic, hanyuma igatera etherifike hamwe na agent.

Ubwoko bwa selile

A. Hydroxypropyl methyl selulose (HPMC), ikozwe cyane cyane muri pamba itunganijwe neza nkibikoresho fatizo, iba idasanzwe cyane mugihe cya alkaline.
B. Hydroxyethyl methylcellulose (HEMC), ether ya ionic selulose ether, ni ifu yera mumiterere, impumuro nziza kandi itaryoshye.
C. Hydroxyethyl selulose (HEC), surfactant idafite ionic, yera mumiterere, impumuro nziza, uburyohe kandi byoroshye gutemba.

Ibyavuzwe haruguru ni ethers ya ionic selulose ethers, na ether ionic selile (nka carboxymethyl selulose CMC).

Mugihe cyo gukoresha ifu yumye yumye, kubera ko ionic selulose (CMC) idahindagurika imbere ya calcium ion, ntabwo ikoreshwa gake muri sisitemu yo gutondeka imiterere ya sima hamwe na lime yamenetse nkibikoresho bya sima. Mu turere tumwe na tumwe two mu Bushinwa, Bimwe mu bikuta by'imbere byatunganijwe hamwe na krahisi yahinduwe nk'ibikoresho by'ibanze bya sima hamwe n'ifu ya Shuangfei nk'uwuzuza akoresha CMC nk'ibyimbye. Nyamara, kubera ko iki gicuruzwa gikunda kurwara kandi kikaba kitarwanya amazi, kigenda gikurwaho nisoko. Kugeza ubu, selile ether ikoreshwa cyane mubushinwa ni HPMC.

Ether ya selile ikoreshwa cyane nkibikoresho byo kubika amazi no kubyimbye mubikoresho bishingiye kuri sima

Igikorwa cyayo cyo gufata amazi kirashobora kubuza substrate gufata amazi menshi kandi bikabuza guhinduka kwamazi, kugirango sima igire amazi ahagije mugihe iyobowe. Fata ibikorwa byo guhomesha urugero. Iyo isima isanzwe ya sima ishyizwe hejuru yubutaka, substrate yumye kandi isukuye izahita ikuramo amazi menshi ava mumashanyarazi, kandi sima ya sima yegereye igiti fatizo izabura byoroshye amazi akenewe kugirango hydrated. , ntabwo rero ishobora gukora gel ya sima gusa ifite imbaraga zo guhuza hejuru ya substrate, ariko kandi irashobora no gukurura no gutembera mumazi, kuburyo hejuru ya sima yubutaka byoroshye kugwa. Iyo grout ikoreshwa ari ntoya, biroroshye kandi gukora ibice muri grout yose. Kubwibyo, mubikorwa byashize byo guhomesha hejuru, amazi akoreshwa muburyo bwo guhanagura substrate mbere, ariko iki gikorwa ntabwo gisaba akazi gusa kandi gitwara igihe, ariko kandi nuburyo bwiza bwibikorwa biragoye kugenzura.

Muri rusange, gufata amazi ya sima byiyongera hamwe no kwiyongera kwa selile ya ether. Ninshi ubwiza bwa selile yongeyeho ether, niko gufata amazi neza.

Usibye kubika amazi no kubyimba, ether ya selile nayo igira ingaruka kubindi bintu bya sima ya sima, nko kudindiza, kwinjiza umwuka, no kongera imbaraga zubucuti. Cellulose ether itinda gushiraho no gukomera kwa sima, bityo bikongerera igihe cyakazi. Kubwibyo, rimwe na rimwe ikoreshwa nka coagulant.

Hamwe niterambere rya minisiteri yumye ivanze,selile etheryahindutse ingirakamaro ya sima. Nyamara, hari ubwoko bwinshi nibisobanuro bya selile ether, kandi ubuziranenge hagati yicyiciro buracyahinduka.
