Kusunga kwamadzi kwa hydroxypypyl methylcellulose ether

Kusunga kwamadzi kwa matope osakaniza kumatanthauza kuthekera kwa matope kuti agwire ndi kutseka madzi. Makutu apamwamba a hydroxypropyll methylcellulose ether, malo abwino osungira. Chifukwa mawonekedwe a cellulose ali ndi ma hydroxyl ndi ma atomu a eyax

Solubility of Hydroxypropyll methyl cellulose ether

1. Coarsobola tinthu cellulose ether ether ndikosavuta kubala m'madzi popanda kuwuma, koma kuphweka kwa chipongwe kumachedwa kwambiri. Cellulose ether pansi 60 mesh imasungunuka m'madzi pafupifupi mphindi 60.

2. Tinthu tating'onoting'ono ether ether ndizosavuta kubala m'madzi popanda kuphatikizika, ndipo chilengedwe chonsecho ndichabwino. Cellulose ether pamwamba 80 midsh imasungunuka m'madzi pafupifupi mphindi zitatu.

3. Cellulose ether pamwamba 120 mesh imasungunuka m'madzi pafupifupi masekondi 10-30.

Wotsiriza mar hydroxypropyll methylcellulose ether, malo abwino osungira. Pamwamba pa cellulose-celluse yopingasa imasungunuka nthawi yomweyo atalumikizana ndi madzi ndipo amapanga gelenomenon. Guluu limakulunga nkhaniyi kuti mupewe mamolekyulu amadzi kuti apitirize kulowa. Nthawi zina sizingafanane mosiyanasiyana ndikusungunuka ngakhale poyambitsa kwa nthawi yayitali, ndikupanga njira yopingasa kapena yovuta. Tinthu tating'onoting'ono tinalimbikitsa ndikusungunuka nthawi yomweyo mutalumikizana ndi madzi kuti apange mavidiyo ofanana.

Mtengo wa PH wa hydroxypropyll methylcellulose ether (kubwezeretsa kapena kuyambitsa mphamvu)

Mtengo wa PH wa hydroxypypyurose ether equose opanga kunyumba ndi kunja kwenikweni pamakhala pafupifupi 7, omwe ali mu boma la acidic. Chifukwa chakuti padakali gawo lalikulu la mphete za anilroglucose pamtundu wa ma cellulose ether, mphete ya anilrogluse ndi gulu lalikulu lomwe limayambitsa kubwezera simenti. Mphete ya anirdrogluc imatha kupanga calcium ma ion mumentium hydration solution courcium ma cell hydraum hydroctions, ndikuchedwetsa hydration wa simenti. njira. Ngati mtengo wa pH uli mumtundu wa alkaline, matopewo adzapezeka munthawi yoyambirira. Tsopano mafakitale ambiri amagwiritsa ntchito sodium carbonate kuti asinthe mtengo wa pH. Sodium Carbonate ndi mtundu wa omwe akuyika mwachangu. Sodium Carbonate imakulitsa mayendedwe a simenti tinthu, imalimbikitsa chilumi pakati pa tinthu, ndikuwonjezeranso mapangidwe a matope. Nthawi yomweyo, sodium Carbonate imaphatikiza ma calcium aony mu matope kuti akweze kukhazikitsidwa kwa Etiringete, ndipo simenti imagwirizana mwachangu. Chifukwa chake, mtengo wa pH uyenera kusinthidwa malinga ndi makasitomala osiyanasiyana pakupanga kwenikweni.

Malo ojambula a mpweya wa hydroxypyl methy cellulose ether ether

Mphamvu ya mpweya wa hydroxypypyll methylcellulose ether ether imatero chifukwa cyulose ether ether imakhalanso mtundu wa zochulukitsa. Ntchito yolumikizira ya cellulose makamaka imachitika pamagesi-madzi ozizira. Choyamba, kuyambitsa kwa mafupa a mpweya, kutsatiridwa ndi kubalalika ndikunyowa. Cellulose ether muli magulu a ma alkyl, zomwe zimachepetsa mphamvu yamadzi, zomwe zimapangitsa kuti zikhale zosavuta kutulutsa thovu yambiri yotsekeka nthawi yosangalatsa yamadzi am'madzi.

Gel katundu wa hydroxypypyl methyl cellulose ether ether

Pambuyo pa hydroxypypyl a methylcellulose ether asungunuka m'matope, methoxyl ndi ma hydroxyl ndi ma hydroxyl a ions pa slurry kuti apangitse mawonekedwe a mafinya ndikudzaza matope a simenti. , sinthani matope a matope, amasewera gawo lodzaza ndi kukongoletsa. Komabe, matrix ophatikizika akapanikizika, mwina polymer sangasewerere mbali yothandiza yothandizira, motero mphamvu ndi kuchuluka kwa matope.

Mapangidwe filimu ya hydroxypropyl methyl cellulose ether ether

Pambuyo pa hydroxypropyl methy cellulose ether ether amawonjezeredwa hydration, woonda woonda wa filimuyo amapangidwa pakati pa tinthu tambiri. Kanemayu ali ndi chisindikizo cha chisindikizo chake ndikuchiritsa chouma cha matope. Chifukwa cha kusungidwa kwamadzi abwino kwa hydroxypropyl etherlllulose etherllulose, mabowokyu amadzi okwanira mkati mwa matope, ndikuwonetsetsa kuti mukulimbana ndi mphamvu, komanso nthawi yomweyo. Amasintha chitoliro cha matope, chimapangitsa matope kukhala ndi pulasitiki yabwino komanso kusinthasintha, ndikuchepetsa ma shriza ndi kusinthika kwa matope.
