Kusunga kwamadzi kwa cellulose ether

Cellulose ether ndi ntchito yogwira ntchito kwambiri pomanga, mankhwala, chakudya, zodzoladzola ndi minda ina. Kusunga kwake kwamadzi ndi chimodzi mwazinthu zofunika kwambiri, makamaka pakugwiritsa ntchito zomanga monga matope ndi simenti. Kusunga kwamadzi kumatanthauza kuthekera kwa cellulose ether ether yotseka mu chinyezi mutatha kuyamwa madzi ndikuletsa kuwonongeka kwa chinyezi mwachangu kwambiri. Khalidwe limangokhudza ntchito yomanga nkhaniyo, komanso imagwiranso ntchito yofunika kwambiri mumphamvu ndi kulimba.

Njira yosungirako madzi a cellulose ether
Ma cellulose ether ali ndi mphamvu kwambiri hydrophilicity, omwe amachokera ku kuchuluka kwakukulu kwa hydroxyl (-oh) magulu ake. Magulu a hydroxyl amalumikizana mosavuta ndi mamolekyulu am'madzi, kulola Ethel Etheluse kuti atenge madzi ambiri. Mu mankhwala am'madzi, cellulose ethel mamolekyulu amatha kupanga mawonekedwe a mitundu itatu, yomwe imaletsa kuyenda kwamadzi ndikuchepetsa madzi opopera, potero ndikuwongolera madziwo.

Cellulose ethemb ikhoza kusintha mtengo wake wamadzi mu kutentha kosiyana ndi minyontho. Mwachitsanzo, malo otentha kwambiri, ma cellulose ether angasinthe madzi osinthika posintha mavickecke, kupewa kusokonekera ndikuwonongeka chifukwa cha kutaya kwamadzi kwambiri kumayambiriro kwa zinthuzo.

Zinthu Zomwe Zimakhudza Kusunga Madzi

1. Mlingo wa zolowa m'malo mwake (DS)

Mulingo wa polowa m'malo mwa ethel ether ndi chinthu chofunikira chokhudza kusungidwa kwamadzi. Mlingo wa cholowa m'malo umakhala magulu omwe ma hydroxyl amagulu a Molelulose amasinthidwa ndi magulu ether. Kukwera kwambiri kwa cholowa m'malo mwake, madzi otetemera ndi madzi osungira ma cellulose. Colllulose wamba monga hydroxypypyl methylcellulose (HPMC) ndi Hydroxethyl Cellulose (Hec) ikhoza kusintha kuchuluka kwa madzi posintha zosowa zosiyanasiyana.

2. Kulemera kwa molecular

Kulemera kwa masere a cellulose ether kumapangitsa kuti madzi azisungidwa. Nthawi zambiri, kulemera kwa maselo, mafayilo a ether ether ndi amphamvu a hydrogel kapangidwe ka mafomu, zomwe zimathandizira kukonza madzi osungira. Komabe, kulemera kwambiri kwa maselo kungayambitse kuchepa kwa zinthuzo, monga madzi ochepetsedwa komanso osavuta kumanga. Chifukwa chake, muzothandiza, ndikofunikira kupeza malire pakati pa kusungidwa kwamadzi komanso ntchito zomanga.

3. Kutentha ndi chinyezi
Kutentha ndi chinyezi ndi zinthu zakunja zomwe zimakhudza kusungidwa kwamadzi kwa celluse. Kutentha kwakuti kutentha kumatha, madzi osinthasintha amathandizira, ndipo cellulose yokhazikika imafunikira kusungidwa kwamphamvu kwa madzi kuthana ndi kusinthaku. M'malo okhala ndi chinyezi chotsika, kusunga kwamadzi kumagwirira ntchito kwa cellulose ndikofunikira kuti zinthu zisakhale madzi mwachangu kwambiri pomanga.

Udindo wamadzi kusungidwa pamapulogalamu osiyanasiyana
1. Kugwiritsa ntchito pomanga zida
Pomanga zida, kusungidwa kwamadzi kwa cellulose kumagwiritsidwa ntchito makamaka pazogulitsa monga matope ndi konkriti. Kusungidwa kwamadzi kwakukulu kumatha kuwonetsetsa kuti zinthuzo zili ndi madzi okwanira panthawi yolimba, potero amalimbikitsa mphamvu ndi kukhazikika. Makamaka zomangira zowonda kapena zowuma kwambiri m'malo owuma, kusungidwa kwamadzi kumatha kupewa mavuto monga kuwonongeka ndi ufa wa zida chifukwa cha kutaya kwa madzi mwachangu.

2. Kugwiritsa ntchito mu gawo lachipatala
M'madongosolo azachipatala, cellulosese yokhazikika imagwiritsidwa ntchito pokonzekera mankhwala opangira mankhwala ngati otsatsa, ma filimu am'manja ndi ovomerezeka omasulira. Madzi ake osasungidwa samangothandiza kutulutsa mankhwala osokoneza bongo m'thupi, komanso kumathandizanso bioavailability wa mankhwala. Kuphatikiza apo, katundu wosunga madzi wa cellulose wakhala akugwiritsidwa ntchito kwambiri pazinthu zosamalira khungu kuti zithandizire kukhala chinyontho cha khungu.

3. Kugwiritsa ntchito makampani ogulitsa zakudya
Cellulose eder amagwiritsidwa ntchito ngati otsanulira, ma emulsifiers ndi okhazikika pamakampani azakudya. Katundu wake wololera madzi amathandizira kukonza kukoma ndi kapangidwe ka chakudya, monganso kusunga chinyontho mu mkate ndi makeke, ndikuwonjezera moyo wa alumali wa zinthu.

Katundu wosunga madzi wokhala ndi madzi ndi maziko a udindo wake wofunikira mu magawo ambiri ofunsira. Pofuna kukonza kuchuluka kwa zowonongeka, kulemera kwa ma cellulose ether ether ethel ethel ethelies, zofunikira pakusungidwa kwamadzi mu minda yosiyanasiyana ikhoza kukwaniritsidwa. M'tsogolo, ndi kukula kwa sayansi ndi ukadaulo, kugwiritsa ntchito kwa cellose kukhala kochulukirapo, ndipo kufunikira kwa nyumba yake yosungira madzi mosiyanasiyana kumawunikiranso.
