Uruhare rwa hydroxypropyl methyl cellulose mu mvange y'amazi

Uruhare rwaHPMCmu gikoresho gitose

Uruvange rw'amazi: Uruvange rw'amazi ni ubwoko bwa sima, uruvange rwiza, imvange n'amazi, kandi hakurikijwe imiterere y'ibice bitandukanye, mu rugero runaka, nyuma yo gupimwa aho bavanga, bivangwa, bigatwarwa aho ikamyo ikoresha, bigashyirwa mu gikoresho cyabugenewe cyo kubikamo ibintu, kandi bigakoreshwa mu gihe cyagenwe uruvange rw'amazi rwarangiye.

Hydroxypropyl methyl cellulose ikoreshwa nk'ikintu gifata amazi mu gukurura sima, gukurura mortar retarder. Muri gypsum nk'igikoresho cyo gufunga kugira ngo inoze ikoreshwa kandi yongere igihe cyo gukora, hydroxypropyl methylcellulose HPMC ifata amazi kugira ngo ururenda nyuma yo kumisha rutazaba rwihuta cyane kandi rukomere, rukongere imbaraga kugira ngo rwongere imbaraga. Gufata amazi ni ingenzi mu gukurura hydroxypropyl methyl cellulose HPMC, kandi ni n'inganda nyinshi zikora mortar zitose. Ibintu bigira ingaruka ku ngaruka zo gufata amazi muri mortar zitose harimo ingano ya HPMC yongewemo, ubukana bwa HPMC, ubuto bw'uduce duto n'ubushyuhe bw'ibidukikije bikoreshwa.
Hydroxypropyl methyl cellulose HPMC mu ruganda rutose rugira uruhare runini mu bintu bitatu, kimwe ni ubushobozi bwiza bwo gufata amazi, icya kabiri ni uburyo icyuma gitose gifatana n'imbaraga za thixotropy, icya gatatu ni uburyo amazi afatwa na sima. Kubika amazi muri eteri ya selulosi biterwa n'uburyo amazi yinjira mu rufatiro, imiterere ya icyuma gitose, ubugari bw'urwego rwa icyuma gitose, gukenera amazi muri icyuma, n'igihe cyo gushyiraho. Uko hydroxypropyl methyl cellulose irushaho kuba nziza, ni ko amazi arushaho kugumana neza.
Ibintu bigira ingaruka ku kubika amazi muri mortilla itose birimo ubushyuhe bwa eteri ya cellulose, kongeramo ingano, ingano y'uduce n'ubushyuhe. Uko eteri ya cellulose iba nini, ni ko amazi arushaho kubika neza. Ubushyuhe ni ikintu cy'ingenzi mu mikorere ya HPMC. Ku gicuruzwa kimwe, gukoresha uburyo butandukanye bwo gupima ubushyuhe bw'ibyavuye mu bushakashatsi biratandukanye cyane, bimwe ndetse binangana na bibiri. Kubwibyo, kugereranya ubushyuhe bigomba gukorwa mu buryo bumwe bwo gupima, harimo ubushyuhe, rotor, nibindi.

Muri rusange, uko amazi arushaho kuba menshi, ni ko amazi arushaho kugumana neza. Ariko, uko amazi arushaho kuba menshi, ni ko uburemere bwa molekile ya HPMC burushaho kuba bwinshi, kandi uko HPMC irushaho gushonga, bigira ingaruka mbi ku mbaraga n'imikorere y'ubwubatsi bwa morti. Uko martique iba nyinshi, ni ko ingaruka z'ubukonje zigaragara, ariko ntabwo bifitanye isano itaziguye. Uko martique iba nyinshi, mortique iba itose, imikorere myiza y'ubwubatsi, imikorere y'ubukonje butose no gufatana cyane n'ubutaka. Ariko, kunoza imbaraga z'ubwubatsi bwa mortique itose ubwabyo ntibyafashije. Ibyubakwa byombi, imikorere ntabwo igaragara ko irwanya kumanika. Mu buryo bunyuranye, hydroxypropyl methylcellulose imwe n'imwe ikoreshwa mu kugabanya ubukonje ariko yahinduwe ifite imikorere myiza mu kunoza imbaraga z'ubwubatsi bwa mortique itose.
Uko ingano ya selulosi ether PMC yongewemo ni ko amazi arushaho kugumana neza, niko ubushyuhe burushaho kuba bwinshi, ni nako amazi arushaho kugumana neza. Ubutoshye nabwo ni ikimenyetso cy'ingenzi cy'imikorere ya selulosi ya hydroxypropyl methyl.
Ubunini bwa hydroxypropyl methyl cellulose nabwo bugira ingaruka ku kubika amazi. Mu bihe bisanzwe, ubunini bumwe n'ubunini butandukanye bwa hydroxypropyl methyl cellulose, iyo hiyongereyeho ingano imwe, niko ubunini bw'ubunini bw'amazi buba bwiza kurushaho.
Muri mortilaire itose, hongerwamo eteri ya celluloseHPMCni nke cyane, ariko ishobora kunoza cyane imikorere y'ubwubatsi bwa morti yoroshye, ni yo nyongeramusaruro nyamukuru igira ingaruka cyane ku mikorere ya mortiyo. Imikorere ya mortiyo yoroshye iterwa cyane no guhitamo neza hydroxypropyl methyl cellulose.
