Mubigize ifu yumye yumye, methyl selulose ni umubare muto wongeyeho, ariko ifite inyongeramusaruro ikomeye ishobora kunoza cyane kuvanga no kubaka imikorere ya minisiteri. Tubivuze mu buryo bworoshe, ibintu hafi ya byose bivangavanze bya minisiteri ishobora kugaragara nijisho ryonyine bitangwa na selile ya ether. Nibikomoka kuri selile yabonetse ukoresheje selile mu biti no mu ipamba, kubyitwaramo na soda ya caustic, no kubitanga hamwe na agent ya etherifying.
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 byatunganijwe hamwe na krahisi yahinduwe nkibikoresho nyamukuru bya sima hamwe nifu ya Shuangfei nkuwuzuza ikoresha CMC nkibyimbye, ariko kubera ko iki gicuruzwa gikunda kwibasirwa nindwara kandi kikaba kitarwanya amazi, kigenda gikurwaho buhoro buhoro. ku isoko. 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 vuba kandi bikabuza guhinduka kwamazi, kugirango tumenye neza ko sima ifite amazi ahagije mugihe iyobowe. Fata ibikorwa byo guhomesha urugero. Iyo isima isanzwe ya sima ishyizwe hejuru yubutaka bwa substrate, substrate yumye kandi isukuye izahita ikuramo amazi menshi ava mumashanyarazi, kandi sima ya sima yegereye substrate izabura byoroshye amazi. Kubwibyo, ntibishobora gusa gukora gel ya sima ifite imbaraga zifatika hejuru ya substrate, ariko nanone byoroshye gutera urujya n'uruza rwamazi, 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, ibikoresho byibanze wasangaga amazi mbere, ariko iki gikorwa cyatwaraga akazi kandi kigatwara igihe, kandi ubwiza bwibikorwa byari bigoye 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 idindiza igenamigambi no gukomera kwa sima, bityo bikongerera igihe cyakazi, kuburyo rimwe na rimwe bikoreshwa nkubuyobozi bwashyizweho.
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.
1. Ibikorwa biranga minisiteri yahinduwe bifitanye isano rya bugufi niterambere rya viscosity ya selile ya 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, ubwiza bwinshi bwa selile ether nabwo bugarukira.
3.Ni ngombwa kugenzura ibyaguzwe, inzira yumusaruro nubugenzuzi bwuruganda kugirango twirinde ihindagurika ryiza.
