Ni ubuhe bwoko bwa methyl selulose ether?
Igisubizo: Hiyongereyeho umubare muto wa methyl selulose ether, kandi imikorere yihariye ya gypsum mortar izanozwa cyane.
(1) Hindura guhuza
Methyl selulose ether ikoreshwa nkibyimbye kugirango ihindure sisitemu.
(2) Guhindura amazi
Muri sisitemu ya gypsumu, amazi akenewe ni ikintu cyingenzi.Amazi yibanze asabwa, hamwe nibisohoka bifitanye isano na minisiteri, biterwa no gukora gypsum ya minisiteri, ni ukuvuga ingano ya hekeste, perlite, nibindi byongeweho.Kwinjiza methyl selulose ether irashobora guhindura neza amazi akenewe hamwe na minisiteri ya gypsum.
(3) Kubika amazi
Kugumana amazi ya methyl selulose ether, umuntu arashobora guhindura igihe cyo gufungura hamwe na coagulation ya sisitemu ya gypsum mortar, kugirango ahindure igihe cyo gukora cya sisitemu;methyl selile ebyiri ether irashobora kurekura buhoro buhoro amazi mugihe kirekire Ubushobozi bwo kwemeza neza isano iri hagati yibicuruzwa na substrate.
(4) Hindura imvugo
Kwiyongera kwa methyl selulose ether birashobora guhindura neza rheologiya ya sisitemu ya gypsum ya plasta, bityo bikazamura imikorere yakazi: minisiteri ya gypsum ifite imikorere myiza, imikorere irwanya anti-sag, nta gufatanya nibikoresho byubwubatsi nibikorwa bya pulping bihanitse, nibindi.
Nigute ushobora guhitamo methyl selulose ikwiye?
Igisubizo: Methyl selulose ether ibicuruzwa bifite ibiranga bitandukanye ukurikije uburyo bwabo bwa etherification, urugero rwa etherification, viscosity yumuti wamazi, ibintu bifatika nkibintu byiza, ibishishwa hamwe nuburyo bwo guhindura.Kugirango ubone ingaruka nziza zo gukoresha, birakenewe guhitamo ikirango gikwiye cya selulose ether kumirima itandukanye, kandi ikirango cyatoranijwe cya methyl selulose ether kigomba guhuzwa na sisitemu ya minisiteri yakoreshejwe.
Methyl selulose ethers iraboneka mumyanya itandukanye kugirango ihuze ibikenewe bitandukanye.Methyl selulose ether irashobora kugira uruhare nyuma yo guseswa, kandi igipimo cyayo cyo kuyasesa igomba guhuzwa numurima wabisabye hamwe nubwubatsi.Ibicuruzwa byiza byifu bikwiranye na sisitemu ya minisiteri yumye (nka spray plaster).Ibice byiza cyane bya methyl selulose ether birashobora gutuma iseswa vuba, kugirango imikorere yayo myiza ikoreshwe neza mugihe gito nyuma yo gushiraho minisiteri itose.Yongera ubudahwema no kubika amazi ya minisiteri mugihe gito cyane.Iyi mikorere irakwiriye cyane cyane mubwubatsi, kuko muri rusange, igihe cyo kuvanga amazi na minisiteri yumye ni gito cyane mugihe cyo kubaka imashini.
Ni ubuhe buryo bwo gufata amazi ya methyl selulose ether?
Igisubizo: Imikorere yingenzi yibyiciro bitandukanye bya methyl selulose ether (MC) nubushobozi bwabo bwo gufata amazi mukubaka sisitemu yibikoresho.Kugirango ubone akazi keza, birakenewe kugumana ubushuhe buhagije muri minisiteri igihe kirekire.Kubera ko amazi akora nk'amavuta yo kwisiga no gukanura hagati y'ibinyabuzima bidafite ingufu, minisiteri yoroheje irashobora gushyirwaho amakarita kandi minisiteri yometseho irashobora gukwirakwizwa hamwe na trowel.Urukuta rudahwitse cyangwa amabati ntibigomba kubanza gutose nyuma yo gukoresha selile yongeyeho selile.MC rero irashobora kuzana ibisubizo byubaka byihuse kandi byubukungu.
Kugirango ushireho, ibikoresho bya sima nka gypsumu bigomba guhuzwa namazi.Umubare wuzuye wa MC urashobora kugumana ubuhehere muri minisiteri igihe kinini gihagije, kugirango igenamigambi no gukomera birashobora gukomeza.Ingano ya MC isabwa kugirango ibone ubushobozi buhagije bwo gufata amazi biterwa no kwinjirira kwishingiro, imiterere ya minisiteri, ubunini bwurwego rwa minisiteri, amazi akenerwa na minisiteri, nigihe cyo kugenera ibikoresho bya sima.
Nubunini buke bwa MC, niko minisiteri yihuta.
