Zotsatira za HPMC hydroxypropyl methylcellulose mumtondo wosakanizidwa wowuma.

Posungira madzi ndi muyeso wa HPMC hydroxypropyl methylcellulose reuse, madzi posungira ntchito zabwino ndi zoipa amakhudzidwa ndi ambiri opanga zoweta za dothi youma, makamaka kutentha kwa nyengo ya kum'mwera fakitale chidwi, pa nthawi yomweyo, panali zifukwa zambiri zimakhudza zotsatira. madzi owuma a ufa wamatope, monga kuwonjezera voliyumu, kukhuthala, kununkhira kwa tinthu komanso kugwiritsa ntchito chilengedwe, kutentha, etc.

Munjira yamatope osakanizidwa owuma, kuchuluka kwa hydroxypropyl methyl cellulose kumakhala kochepa.Ngakhale kuti ndalama zowonjezerazo ndizochepa, mwachiwonekere zimatha kupititsa patsogolo ntchito yamatope, omwenso ndi chowonjezera chachikulu chomwe chimakhudza ntchito yomanga matope.Choncho, sayansi ndi wololera kusankha mapadi efa ndi zopangidwa zosiyanasiyana, kukhuthala osiyana, osiyana tinthu fineness ndi kuwonjezera kuchuluka ali ndi chikoka chachikulu pa kusintha youma-osakaniza okonzeka osakaniza matope ntchito.

Kwa chilengedwe chamakono chomanga, tsopano ntchito zambiri zomanga ndi matope opangira madzi si abwino, malo opanda phokoso kwa mphindi zingapo angakhale kulekanitsa kwamadzi, ndi kusunga madzi ndi hydroxypropyl methylcellulose ether, gawo lalikulu la cellulose ether. okonzeka wothira matope ali ndi udindo wofunika kwambiri, udindo waukulu padziko ali atatu, mmodzi, Ndi bwino madzi posungira ntchito, kachiwiri, chikoka pa kugwirizana ndi thixotropy wa okonzeka osakaniza matope, chachitatu, chikoka cha mogwirizana ndi simenti. .Hydroxypropyl methylcellulose kasungidwe ka madzi makamaka zimatengera maziko a mayamwidwe amadzi, kapangidwe ka matope, makulidwe a matope, ndi zofunika zamadzi amtondo, komanso nthawi ya condensation ya zinthu za condensation, posungirako madzi a cellulose ether, makamaka kuchokera kusungunuka kwachilengedwe ndi kutaya madzi m'thupi. wa celluloseether.

Hydroxypropyl methylcellulose imagwira ntchito yofunika kwambiri popanga matope osakaniza okonzeka, omwe amatha kugwira ntchito posungira madzi, kuwonjezereka, kuchepetsa mphamvu ya hydration ya simenti, ndipo akhoza kupititsa patsogolo ntchito yomanga.Kuchita bwino kwa kusunga madzi kungapangitse kuti simenti ikhale yokwanira, imatha kusintha kukhuthala konyowa kwa matope onyowa, kuti apititse patsogolo mphamvu zomangira zamatope, komanso kusintha nthawi.Kuwonjezera hydroxypropyl methylcellulose efa mu ndondomeko youma wosanganiza matope okonzeka wothira akhoza kusintha ntchito yomanga matope, akhoza kusintha mphamvu structural, kuti chimagwiritsidwa ntchito m'munda wa ntchito matope.
