Uruhare rwa hydroxypropyl methyl selulose muri minisiteri itose

Uruhare rwaHPMCmuri minisiteri itose

Amashanyarazi avanze neza: Imvange ivanze ni ubwoko bwa sima, igiteranyo cyiza, kivanze n’amazi, kandi ukurikije imiterere yibigize bitandukanye, ku kigero runaka, nyuma yo gupimirwa kuri sitasiyo ivanga, kuvanga, kujyanwa ahantu byakoreshejwe n'ikamyo, mu bikoresho byabitswe byabugenewe, kandi bigakoreshwa mu gihe cyagenwe kivanze cyuzuye cyuzuye.

Hydroxypropyl methyl selulose ikoreshwa nkibikoresho bigumana amazi ya sima ya pome, retarder mortar pompe. Muri gypsumu nkibikoresho byo kunoza porogaramu no kongera igihe cyo gukora, hydroxypropyl methylcellulose HPMC kubika amazi kugirango ibishishwa nyuma yo kumisha bitihuta cyane kandi bikavunika, bikomera kugirango byongere imbaraga. Kubika amazi ni umutungo w'ingenzi wa hydroxypropyl methyl selulose HPMC, kandi ni nacyo gihangayikishije abakora inganda nyinshi. Ibintu bigira ingaruka ku gufata amazi ya minisiteri itose harimo ingano ya HPMC yongeyeho, ubwiza bwa HPMC, ubwiza bwibice hamwe nubushyuhe bwibidukikije bikoreshwa.
Hydroxypropyl methyl selulose HPMC mubikorwa byingenzi bya minisiteri yibice bitatu, kimwe nubushobozi buhebuje bwo gufata amazi, icya kabiri nuburinganire bwa minisiteri itose hamwe na thixotropy yingaruka, icya gatatu ni imikoranire na sima. Kugumana amazi ya selulose ether biterwa nigipimo cyo kwinjiza amazi yibanze, ibice bya minisiteri, uburebure bwa minisiteri, amazi ya minisiteri, igihe cyagenwe. Iyo hejuru ya hydroxypropyl methyl selulose, niko gufata amazi neza.
Mu bintu bigira ingaruka ku kugumana amazi ya minisiteri itose harimo ubwiza bwa selulose ether, wongeyeho ingano, ingano yubushyuhe n'ubushyuhe. Ninshi ubwiza bwa selulose ether, niko gufata amazi neza. Viscosity nikintu cyingenzi kumikorere ya HPMC. Kubicuruzwa bimwe, ukoresheje uburyo butandukanye bwo gupima ubwiza bwibisubizo biratandukanye cyane, bimwe ndetse nibintu bibiri. Kubwibyo, kugereranya ibishishwa bigomba gukorwa muburyo bumwe bwo gupima, harimo ubushyuhe, rotor, nibindi.

Muri rusange, hejuru yubukonje, niko gufata amazi neza. Nyamara, uko hejuru yubukonje, niko uburemere bwa molekuline ya HPMC, kandi niko kugabanuka kwa HPMC, bigira ingaruka mbi ku mbaraga n’imikorere ya minisiteri. Iyo hejuru ya viscosity, niko bigaragara cyane kubyimbye bya minisiteri, ariko ntabwo bifitanye isano itaziguye. Iyo hejuru yubukonje, niko gufatana na minisiteri itose, imikorere myiza yubwubatsi, gukora scraper viscous hamwe no gufatira hejuru kuri substrate. Ariko, kuzamura imbaraga zuburyo bwa minisiteri itose ubwayo ntacyo byafashije. Byombi byubaka, imikorere ntabwo igaragara anti - kumanika imikorere. Ibinyuranye, ibicu bito n'ibiciriritse ariko byahinduwe na hydroxypropyl methylcellulose bifite imikorere myiza mugutezimbere imiterere yimiterere ya minisiteri.
Umubare munini wa selulose ether PMC wongeyeho minisiteri yongeweho, niko gufata amazi neza, niko ubukonje bwinshi, niko gufata amazi neza. Ubwiza nabwo ni indangagaciro yingenzi ya hydroxypropyl methyl selulose.
Ubwiza bwa hydroxypropyl methyl selulose nabwo bugira uruhare runini mu gufata amazi. Mubihe bisanzwe, ubwiza bumwe nubwiza butandukanye bwa hydroxypropyl methyl selulose, mugihe cyongeweho kimwe, ntoya ubwiza bwingaruka zo gufata amazi nibyiza.
Muri minisiteri itose, hiyongereyeho selile etherHPMCni hasi cyane, ariko irashobora kunoza cyane imikorere yubwubatsi bwa minisiteri itose, ninyongera nyamukuru igira ingaruka cyane cyane kumikorere ya minisiteri. Imikorere ya minisiteri itose iterwa cyane no guhitamo neza hydroxypropyl methyl selulose
