Ubwoko bwa Methyl Cellulose Ether
A． Hydroxypropyl methylcellulose (HPMC) ikozwe cyane cyane muri pamba itunganijwe neza nkibikoresho fatizo, byera cyane cyane mubihe bya alkaline.
B. Hydroxyethyl methyl selulose (HEMC), ether ya selile idafite ionic, ni ifu yera, idafite impumuro nziza kandi itaryoshye.
C． Hydroxyethylcellulose (HEC) ni surfactant idafite ionic, yera mumiterere, impumuro nziza kandi itaryoshye kandi ifu yoroshye.
Ibyavuzwe haruguru ni ether ya ionic selulose ethers, hamwe na ionic selulose ethers (nka carboxymethyl selulose (CMC)).
Mugihe cyo gukoresha ifu yumye yumye, kubera ko ionic selulose (CMC) idahindagurika imbere ya calcium ya calcium, ntabwo ikoreshwa gake muri sisitemu yo gutondeka imiterere idasanzwe hamwe na sima hamwe nindimu zometse nkibikoresho bya sima. Mu turere tumwe na tumwe two mu Bushinwa, Bimwe mu bikuta by’imbere bitunganijwe hamwe na krahisi yahinduwe nkibikoresho nyamukuru bya sima hamwe nifu ya Shuangfei nkuwuzuza ikoresha CMC nkibyimbye, ariko kubera ko iki gicuruzwa gikunda kwibasirwa n’indwara kandi kikaba kitarwanya amazi, kigenda gikurwaho buhoro buhoro. ku isoko.
Kugeza ubu, ether ikoreshwa cyane muri selile mu bicuruzwa byumye biva mu rugo byitwa hydroxypropyl methylcellulose ether (HPMC) na hydroxyethyl methylcellulose ether (HEMC). Kubicuruzwa bifite imikoreshereze itandukanye, dosiye ya selile ya ether nayo iratandukanye, munsi ya 0,02% nka minisiteri yurukuta kugeza 0.1%. Nka pompe ya pompe, hejuru irashobora kuva kuri 0.3% kugeza 0.7% nka tile yometse.
Ibyiza bya Cellulose Ether
Ether Cellulose ether ifite amazi meza muri minisiteri. Igikorwa cyayo cyo gufata amazi kirashobora kubuza substrate gufata amazi menshi vuba kandi bikabuza guhinduka kwamazi, kugirango habeho amazi ahagije mugihe sima iyobowe. Irashobora gukumira neza minisiteri gukama no guturika kubera gutakaza amazi byihuse, kuburyo minisiteri ifite igihe kirekire cyo kubaka.
Muri rusange, gufata amazi ya sima byiyongera hamwe no kwiyongera kwa selile ya ether. Ninshi ubwiza bwa selile yongeyeho ether, niko gufata amazi neza.
Ingaruka yibyibushye bya selile ya ether irashobora kugenzura minisiteri kugirango igere kumurongo mwiza, kunoza ubumwe bwa minisiteri, kugera kuri anti-sag, kunoza imikorere, no kongera imikorere yubwubatsi.
Ether Cellulose ether irashobora kunoza cyane ubwiza bwamazi ya minisiteri itose, ikemeza ko minisiteri itose igira ingaruka nziza muburyo butandukanye.
Ether Cellulose ether itezimbere cyane imbaraga zumubano wa minisiteri, kandi irashobora gutuma igihe cyamazi gihagije cyo kuvoma neza sima ndetse no mubushuhe bwo hejuru, bityo bigatuma ubwuzuzanye bwiza bwa minisiteri.
Umwanya wo gukoresha selile
Sima ishingiye:
. ⑾, minisiteri yububoshyi, ⑿, gusana minisiteri, ⒀, gutondekanya ubushyuhe bwumuriro, ⒁, EIFS yubushyuhe bwumuriro uhuza minisiteri, ⒂, ibikoresho bitavunika.
Ibindi bikoresho byo kubaka:
⑴, minisiteri itagira amazi, ⑵, ibice bibiri bigize minisiteri.
Hamwe niterambere rya minisiteri yumye, selulose ether yahindutse sima yingenzi ya sima. Nyamara, hari ubwoko bwinshi nibisobanuro bya selile ether, kandi ubuziranenge hagati yicyiciro buracyahinduka. Mugihe uyikoresha, ugomba kwitondera:
1. Ibikorwa biranga minisiteri yahinduwe bifitanye isano rya bugufi niterambere ryubwiza bwa selile ether. Nubwo ibicuruzwa bifite ubwiza bwizina ryinshi bifite ubukana bwanyuma bwanyuma, kubera gushonga buhoro, bisaba igihe kirekire kugirango ubone ubwiza bwa nyuma; hiyongereyeho, selile ya ether hamwe na coarser ibice bifata igihe kinini kugirango ibone ubwiza bwa nyuma, bityo ibicuruzwa bifite ububobere buke ntabwo byanze bikunze bifite imikorere myiza.
2. Bitewe no kugabanuka kurwego rwa polymerisation ya selulose ether yibikoresho fatizo, ububobere ntarengwa bwa selile ya ether nayo irahari.
