Ndi zifukwa ziti zomwe zimakhudza kusungidwa kwamadzi kwa hydroxypropyl methyl cellulose?

Kukula kwa ma virus a hydroxypropyl methyl cellulose, kusungitsa kwamadzi. Makulidwe ndi gawo lofunikira la hpmc. Pakadali pano, opanga anzawo osiyanasiyana amagwiritsa ntchito njira zosiyanasiyana zoyezera mafayilo a HPMC. Njira zazikuluzikulu zimaphatikizapo Haarhatovisko, Huspler, Ulonda wa Ulonda ndi Brookfield.

Pazinthu zomwezo, zotsatira za ufa zimayesedwa ndi njira zosiyanasiyana zimasiyanasiyana, ndipo zina zimachulukana. Chifukwa chake, poyerekeza mawonekedwe, ziyenera kuchitidwa pakati pa njira yoyeserera yomweyi, kuphatikiza kutentha, rotor, etc.

Kwa kukula kwa tinthu tating'onoting'ono, ndikulimbikitsa tinthu tambiri, kukonzanso kwamadzi. Pambuyo pa tinthu tambiri ta kulumikizana ndi madzi, mawonekedwe ake nthawi yomweyo amasungunuka ndipo amapanga gel kuti mukulungiritse ma mamolekyulu amadzi kuti asungunuke. Nthawi zina, ngakhale nthawi yayitali yodzudzulidwa silingathe kubalalika komanso kusungunuka, ndikupanga njira yoyatsira moto kapena kutsekera. Kusunga kwamadzi kwa ethel ethel kumakhudzidwa kwambiri, ndipo kusungunuka ndi chimodzi mwazinthu zomwe zimasankha cellulose ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether.

Ubwino ndi mndandanda wofunikira wa methyl cellulose ether. MC ya matope owuma imafuna ufa, zamadzi ochepa, ndipo zabwino zimafunikiranso 20% -60% tinthu tambiri 63um. Kuchita bwino kumakhudza kusungunuka kwa hydroxypropyl methl cellulose ether ether. Coarsder Mc nthawi zambiri amasungunuka ndikusungunuka mosavuta m'madzi osatseka, koma kufooka kwa chilengedwe kumakhala kocheperako ndipo sioyenera kugwiritsa ntchito mativa owuma.

Mu matope owuma, MC imabalalitsidwa pakati pa ophatikizika, filler yabwino Pamene MC yasungunuka m'madzi, ndikovuta kupasulidwa pakubala. MC yokhala ndi mapidwe a Coarder Kusavulaza, komanso amachepetsa mphamvu ya matope. Matope owuma ngati owuma atamangidwa m'dera lalikulu, likuwonetsedwa kuti liwiro la matope lowuma limachepa kwambiri, ndipo kusokonekera kumachitika chifukwa chothira nthawi yosiyanasiyana. Kwa matope a mfuti ndi zomangamanga zamakina, chifukwa nthawi yosakanikirana ndi yofupikira, zofunikira zabwino ndizokwera.

Nthawi zambiri, mafakiti apamwamba, abwinobwino amadzisungira madzi. Komabe, mafayilo apamwamba ali, olemera kwambiri kwa MC ndi, ndipo molongosoka MC ichepa, yomwe imasokoneza mphamvu ndi matope omanga matope. Maonekedwe akuwoneka, zoonekeratu zotsatira zam'matambo, koma sizofanana ndi ubale. Matope apamwamba, nthawi yonyowa kwambiri idzakhala, nthawi yonse yomanga, ntchito ya zomata zomata komanso kutsatira kwambiri mpaka gawo lapansi. Koma sikothandiza kuwonjezera mphamvu yonyowa yonyowa. Ntchito yomanga, ntchito ya anti - Droop sizachidziwikire. Mosiyana ndi zimenezo, kusinthidwa kwa medi ya meya ya medi ya medi yapakati komanso kotsika kuli ndi luso labwino kwambiri pokonzanso mphamvu ya matope onyowa.

Kuchuluka kwa cellulose ether ether owonjezera matope, magwiridwe antchito abwino a madzi, ma viscket, omwe ali ndi magwiridwe antchito.

Kuchita bwino kwa HPMC kumakhudzanso njira ina pamadzi ake, nthawi zambiri amawoneka bwino komanso kukoma kwa methyl cely ether ether ether ether ether ethel celluse ether.

Kusunga kwamadzi kwa HPMC kumakhudzananso ndi kutentha komwe kumagwiritsidwa ntchito, ndipo madzi osungira madzi a methyl cellulose ethel ether amachepetsa ndi kukwera kwa kutentha. Koma mu kugwiritsa ntchito matope, matope ambiri owuma nthawi zambiri amakhala kutentha kwambiri (madigiri 40) pansi pa zomanga padzuwa m'chilimwe, omwe nthawi zambiri amathandizira kuchiritsa kwa simenti ndi kuuma kwa matope.

Kutsika kwa kuchuluka kwa malire kwamadzi kumadzetsa kumverera kowonekeratu komwe kungakhale koyenera komanso kusokonekera kumakhudzidwa. Panthawi yotere, zimakhala zovuta kuti muchepetse mphamvu ya kutentha. Ngakhale methyhydroxyethyl cellulose eleulose yowonjezera imadziwika kuti ndi kutsogolo kwa chitukuko cha ukadaulo, kudalira kwake kumabweretsabe kufooketsa matope owuma.

Kuchulukitsa Mlingo wa methyl hydrothyl cellulose, zomangamanga komanso kukana kukanabe zofuna kugwiritsa ntchito. MC kudzera mwathandizo ena mwapadera, monga kukonza kuchuluka kwa chikondwerero, kumapangitsa kuti madzi ake athe kugwiritsa ntchito kutentha kwambiri kuti ukhale wabwino kwambiri, kuti uzitha kugwira bwino ntchito.
