Njira yoyesera kuti musungidwe kwamadzi a cellulose et

Cellulose etrars, mongamethylcellulose (MC),hydroxypropyl methylcellulose (hpmc), ndipoCarboxymethyl cellulose (cmc), amagwiritsidwa ntchito kwambiri pamapulogalamu osiyanasiyana kuphatikiza mankhwala, zomangamanga, ndi mafakitale. Chimodzi mwazovuta kwambiri za cellulose eds ndi kuthekera kwawo kusunga madzi, komwe ndikofunikira kuti azigwira ntchito mu izi. Kubwezera kwamadzi kumatsimikizira kuti zinthuzo zikhalabe mu mawonekedwe azomwe angafunidwa ndikugwira bwino ntchito, kaya mu soncyent soluse, gel osakaniza.

1.Wolingalira bwino

Cholinga cha mayeso osunga madzi ndikuwonjezera kuchuluka kwa madzi ether ether amatha kulimbana nawo. Katunduyu ndi wofunikira chifukwa umakhudza kugwirira ntchito, kukhazikika, ndi magwiridwe antchito a cellulose omwe ali m'malo osiyanasiyana.

2.Maganizo

Kusungidwa kwamadzi kumatsimikiziridwa ndikuyeza kulemera kwamadzi omwe amasungidwa ndi ma cellulose ether ether atayesedwa. Nthawi zambiri, osakaniza a cellulose amakonzedwa ndi madzi, kenako kuchuluka kwa madzi omasulidwa kapena oyendetsedwa kuchokera osasakaniza. Kusungidwa kwamadzi, kuthekera kwakukulu kwa cellulose ether kuti ikhale chinyezi.

3.AppAratos ndi zida

CHINSINSI CHAKE:Cellulose ether ufa (mwachitsanzo, mc, hpmc, cmc)

Madzi (osokoneza)- Kukonzekera kusakaniza

Ziphuphu zamadzi- Chiyeso chosungidwa chamadzi chokwanira (mwachitsanzo, chimakhala cholumikizira cha mesh kapena chida chofiyira)

Kutsalira- kuyeza zitsanzo ndi madzi

Pepala- Posunga chitsanzo

Maphunziro Omaliza Maphunziro- Kuyeza kuchuluka kwa madzi

Kukakamizidwa- kufinya madzi owonjezera (mwachitsanzo, makina osindikizira kapena kulemera)

Ikanthawi- Kutsata nthawi yopepuka madzi

Thermostat kapena chofungatira- kukhala ndi kutentha (mwachisawawa firiji, pafupifupi 20-25 ° C)

4.Machitidwe

Kukonzekera kwa zitsanzo:

Yendani kuchuluka kwa ma cellulose (kawirikawiri grams) molondola.

Sakanizani ufa wa cellulose wokhala ndi kuchuluka kwa madzi osungunuka (mwachitsanzo, 100 ml) kuti apange slurry kapena phala. Yambitsa osakaniza bwino kuonetsetsa kuti mulumikizane ndi kupezeka kwa yunifolomu ndi hydration.

Lolani kusakaniza kwa hydrate kwa mphindi 30 kuti muwonetsetse kuti cellulose ether ether ether.

Kukhazikitsa kwa Zida Zosunga Madzi:

Konzani zida zosungira madzi poika pepala losefera mu gawo la ku FALISTRATRATERT CATION kapena.

Thirani ma cellulose elerry papepala lazosefera ndikuwonetsetsa kuti afalikira.

Kuyeza Mwalamulo:

Gwiritsani ntchito kukakamiza kwa zitsanzo zamanja kapena pogwiritsa ntchito makina osindikizira masika. Kuchuluka kwa zovuta kuyenera kukhazikika pamayeso onse.

Lolani dongosolo kukhetsa kwa mphindi 5-10, pomwe madzi ochulukirapo adzalekanitsidwa ndi kusalala.

Sungani madzi osefera mu silinda yomaliza maphunziro.

Kuwerengera kwamadzi kusungitsa:

Pambuyo kuwunika ndikwanira, kumangiriza madzi osungidwa kuti muwone kuchuluka kwa madzi otayika.

Kuwerengera kusungidwa kwamadzi mwakuchotsa kuchuluka kwa madzi aulere ochokera kumadzi oyamba omwe amagwiritsidwa ntchito mu zitsanzo zosakaniza.

Kubwerezabwereza:

Chitani mayesowo mu katatu pa cellulose iliyonse ya ether kuti mutsimikizire zotsatira zolondola komanso zotheka. Mtengo wosunga madzi wamba umagwiritsidwa ntchito pofotokoza mawu.

5.Kutanthauzira kwa data

Zotsatira za mayeso osunga madzi nthawi zambiri zimafotokozedwa ngati kuchuluka kwamadzi kusungidwa ndi ma cellulose ether. Njira yowerengera madzi osafunikira ndi:

Fomu iyi imathandizira kuyesa kuchuluka kwam'madzi kwa cellulose etress mikhalidwe yomwe yatsimikizika.

6.Kuyeserera kusiyanasiyana

Kusintha kwina kwa mayeso osungirako madzi ndi:

Kusunga kwamadzi kodalira:Nthawi zina, kusungidwa kwamadzi kumatha kuwerengedwa nthawi zosiyanasiyana (mwachitsanzo, 5, 10, 10, 15, 15) kumvetsetsa kinetics posungira madzi.

Kusunga kutentha:Mayeso omwe amachitika potentha zosiyanasiyana amatha kuwonetsa momwe kutentha kumakhudzira kusungidwa kwamadzi, makamaka zinthu zokhudzana ndi thupi.

7.Zinthu Zomwe Zimakhudza Kusunga Madzi

Pali zinthu zingapo zomwe zingapangitse kusungidwa kwamadzi kwa cellulose etrase:

Makulidwe:Cellulose etrave okhala ndi mamasukidwe apamwamba amakonda kusunga madzi ambiri.

Kulemera kwa maselo:Cellulose yapamwamba kwambiri cellulose yolemera ma eds nthawi zambiri imakhala ndi vuto la madzi bwino chifukwa cha mawonekedwe awo akuluakulu.

Mlingo wazolowaKusintha kwa mankhwala kwa cellulose et (mwachitsanzo, digiri ya methylation kapena hydroxypropropropropropropy) imatha kukhudza kwambiri madzi awo osasunga madzi.

Kukhazikika kwa cellulose ether mu osakaniza:Kuchuluka kwa cellulose ether nthawi zambiri kumapangitsa kusungidwa kwamadzi.

8.Gome Lachiwiri: Zitsanzo Zotsatira

Mwachitsanzo ichi, mfundo zosungidwa zamadzi zikuwonetsa kuti carboxymethyl cellouse (cmc) mosungika kwambiri, pomwe methylllulose (MC) ikusungidwa kwambiri.

Kuyesa kwamadzi kwam'madzi kwa cellulose ndi njira yofunika yoyendetsera khalidwe labwino kuyeza kukhoza kwa zinthuzi kunyamula madzi. Zotsatira zimathandizira kudziwa kufunika kwa ethel ether fortinations apadera, monga momwe mukupangira chinyezi ndikofunikira. Pogwiritsa ntchito njira yoyeserera, opanga amatha kuwonetsetsa magwiridwe antchito a cellulose ndikupereka deta yothandiza pakupanga malonda.
