Uruhare rwa hydroxypropyl methylcellulose muri minisiteri itose

Amashanyarazi avanze neza: minisiteri ivanze ni ubwoko bwa sima, igiteranyo cyiza, kivanga n’amazi, kandi ukurikije imiterere yibigize bitandukanye, ukurikije igipimo runaka, nyuma yo gupimirwa kuri sitasiyo ivanga, kuvanga, kujyanwa ahantu aho ikamyo irakoreshwa, kandi yinjiye mububiko bwihariye kontineri hanyuma ukoreshe uruvange rwuzuye rwuzuye mugihe cyagenwe.

Hydroxypropyl methylcellulose ikoreshwa nkigikoresho cyo kubika amazi kubutaka bwa sima na retarder yo kuvoma minisiteri. Kubijyanye na gypsumu nkibikoresho byo kunoza imikoreshereze no kongera igihe cyakazi, kugumana amazi ya HPMC birinda gutemba vuba vuba nyuma yo gukama, kandi bikongerera imbaraga nyuma yo gukomera. Kubika amazi ni umutungo w'ingenzi wa hydroxypropyl methylcellulose HPMC, kandi ni impungenge na benshi mu bakora uruganda rwa minisiteri ivanze. Ibintu bigira ingaruka ku gufata amazi ya minisiteri ivanze n’amazi arimo ingano ya HPMC yongeweho, ubwiza bwa HPMC, ubwiza bwibice hamwe nubushyuhe bwibidukikije bikoreshwa.

Hariho ibikorwa bitatu by'ingenzi bya hydroxypropyl methylcellulose HPMC muri minisiteri ivanze, imwe nubushobozi buhebuje bwo gufata amazi, indi ni ingaruka ku guhuza hamwe na thixotropy ya minisiteri ivanze, naho icya gatatu ni imikoranire na sima. Kugumana amazi ya selile ya selile biterwa nigipimo cyo kwinjiza amazi yikibanza, imiterere ya minisiteri, ubunini bwurwego rwa minisiteri, amazi akenerwa na minisiteri, nigihe cyagenwe. Iyo hejuru ya hydroxypropyl methylcellulose, niko gufata amazi neza.

Ibintu bigira ingaruka ku gufata amazi ya minisiteri ivanze harimo selile ya ether viscosity, umubare wongeyeho, ingano yubushyuhe n'ubushyuhe. Ninshi ubwiza bwa selulose ether, niko gufata amazi neza. Viscosity nikintu cyingenzi cyimikorere ya HPMC. Kubicuruzwa bimwe, ibisubizo byo gukoresha uburyo butandukanye bwo gupima ubukonje buratandukanye cyane, ndetse bamwe bafite icyuho kabiri. Kubwibyo, kugereranya viscosity bigomba gukorwa muburyo bumwe bwo gupima, harimo ubushyuhe, spindle, nibindi.

Muri rusange, hejuru yubukonje, niko gufata amazi neza. Nyamara, uko ubukonje buri hejuru, niko uburemere bwa molekuline ya HPMC bugabanuka no kugabanuka kwa HPMC, bigira ingaruka mbi ku mbaraga n’imikorere yubwubatsi bwa minisiteri. Iyo hejuru ya viscosity, niko bigaragara cyane kubyimbye bya minisiteri, ariko ntabwo bifitanye isano itaziguye. Iyo hejuru ya viscosity, niko igaragara cyane ya minisiteri itose, niko imikorere myiza yubwubatsi, imikorere ya scraper ya viscous kandi niko gufatira kuri substrate. Ariko, imbaraga ziyongereye zububiko bwa minisiteri itose ubwayo ntabwo ifasha. Inyubako zombi ntizigaragaza imikorere irwanya sag. Ibinyuranye, ibicu bito n'ibiciriritse ariko byahinduwe na hydroxypropyl methylcellulose bifite imikorere myiza mugutezimbere imiterere yimiterere ya minisiteri.

Umubare munini wa selulose ether wongeyeho kuri PMC itose, niko gufata neza amazi, hamwe nubukonje bwinshi, niko gufata amazi neza. Ubwiza nabwo bwerekana imikorere yingenzi ya hydroxypropyl methylcellulose.

Ubwiza bwa hydroxypropyl methylcellulose nabwo bugira uruhare runini mu gufata amazi. Muri rusange, kuri hydroxypropyl methylcellulose ifite ubwiza bumwe nubwiza butandukanye, uko ubwiza buke, niko ingaruka zo gufata amazi ari munsi yinyongera. ibyiza.

Muri minisiteri ivanze n’amazi, inyongera ya selile ether HPMC iri hasi cyane, ariko irashobora kunoza cyane imikorere yubwubatsi bwa minisiteri itose, kandi ninyongera nyamukuru igira ingaruka cyane cyane kumikorere ya minisiteri. Guhitamo neza hydroxypropyl methylcellulose, imikorere ya minisiteri itose bigira ingaruka cyane.
