1. Kuyamba
Hydroxypropyl methylcellulose (hpmc) ndizopanga cellulose wopangidwa mwaluso kwambiri pazomangira, kukonzekera kwamankhwala, zowonjezera chakudya komanso zodzoladzola. Kusungidwa kwake kwabwino ndi chimodzi mwazinthu zazikulu za ntchito yayikulu ya HPMC.
2. Kapangidwe ndi katundu wa HPMC
2.1 kapangidwe ka mankhwala
HPMC ndi gawo lopanga celluuse. Ma hydroxypyl ndi methyl oyang'anira mapangidwe apadera amapereka kusungunuka kwapadera komanso katundu wapadera. Kapangidwe ka HPMC kuli ndi maunyolo a β-d-glucose a cellulose, komwe magulu ena a hydroxyl amasinthidwa ndi ma methyl ndi hydroxypyl magulu. Maudindo ndi kuchuluka kwa zomwe zili m'malo mwa izi zimakhudza molunjika kusungunuka, mafakisoni ndi madzi osungira a HPMC.
2.2 katundu wakuthupi
Kusungunuka kwamadzi: HPMC imasungunuka mosavuta m'madzi ozizira ndikupanga njira ya colloidal m'madzi otentha.
Katundu wambiri: imatha kupanga njira yothetsera ma viscous m'madzi ndipo imakhala ndi kukula kokulirapo.
Katundu wopanga mawonekedwe a filimu: Imatha kupanga filimu yowonekera komanso yopingasa.
Kuyimitsidwa: ili ndi kuyimitsidwa kwabwino kumagwirira ntchito mu yankho ndipo amatha kukhazikika.
3. Kusunga kwamadzi kwa HPMC
3.1 Njira Yosunga Madzi
Kusunga kwamadzi kwa HPMC kumadziwika kuti kulumikizana pakati pa hydroxyl ndi magulu osokoneza bongo ndi mamolekyulu amadzi. Makamaka, HPMC imasunganso madzi pogwiritsa ntchito njira zotsatirazi:
Kuphatikizira hydrogen: Magulu a hydroxyl mu mamolekyu a HPMC amapanga ma bondo a hydrogen ndi mamolekyulu amadzi. Mphamvuyi imathandizira ma mamolekyu amadzi kuti athe omangidwa mozungulira hpmc, kuchepetsa madzi omasulira.
Mphamvu ya MayCecy: Njira yothetsera magazi kwambiri yopangidwa ndi HPMC m'madzi imatha kulepheretsa kuyenda kwa madzi, potero kuchepetsa kuchepa kwa madzi.
Kapangidwe ka network: Ma netiweki opangidwa ndi HPMC m'madzi amatha kugwira ndikusunga mamolekyulu amadzi, kuti madziwo amagawidwanso mu netiweki.
Colloid zotsatira: Colloid yopangidwa ndi HPMC imatha kutseka madzi mkati mwa Colloid ndikuwonjezera nthawi yosunga madzi.
3.2 Zinthu Zomwe Zimakhudza Kusunga Madzi
Madigirikiti a zolowa: Kusunga kwamadzi kwa HPMC kumakhudzidwa ndi kuchuluka kwa malo olowa m'malo mwake (DS). Kuchuluka kwa kulowetsa, kulimba kwa HPMC komanso bwino magwiridwe ake.
Kulemera kwa maselo: Kulemera kwapamwamba kumathandizira kupanga netiweki kakang'ono kwambiri, potengera kukonza madzi.
Kuzindikira: Kukhazikika kwa HPMC yankho kumathandizanso posungira madzi. Mayankho ochulukirapo amatha kupanga njira zina zosinthira komanso zomangira zina zokhazikika pamaneti, poti tisunge madzi ambiri.
Kutentha kwa madzi ku HPMC kumasiyana ndi kutentha. Kutentha kukakwera, mafayilo a HPMC yankho la HPMC limachepa, zomwe zimapangitsa kuchepa kwamadzi kusungidwa kwamadzi.
4. Kugwiritsa ntchito HPMC m'malo osiyanasiyana
4.1 Zomangira
Pomanga zida, HPMC imagwiritsidwa ntchito ngati chosungira chamadzi kwa mankhwala a simenti ndi gypsum. Ntchito zake zazikulu zikuphatikiza:
Sinthani magwiridwe antchito omanga: Mwa kusunga chinyezi choyenera, nthawi yotseguka ya simenti ndi gypsum imakulitsidwa, kupanga njira yomangayi.
Kuchepetsa ming'alu: Kusunga kwamadzi kumathandiza kuchepetsa ming'alu yopangidwa nthawi yowuma ndikusintha mphamvu ndi kukhazikika kwa zinthu zomaliza.
Kupititsa patsogolo kulimbitsa ubwenzi: m'matate a tile, hpmc imatha kuwonjezera mphamvu ndikuwonjezera mgwirizano.
4.2 Kukonzekera kwa mankhwala
Kukonzekera kwa mankhwala opanga mankhwala, kugwiritsa ntchito madzi ku HPMC kumagwira mbali yofunika kwambiri pakutulutsa mankhwalawa:
Kukonzekera kokhazikika: HPMC itha kugwiritsidwa ntchito ngati matrix omasulidwa kuti athe kumasulidwa mankhwala pakuwongolera kulowa kwa madzi ndi kuchuluka kwa mankhwala osokoneza bongo.
Otsatsa ndi ma binders: mankhwala amadzimadzi ndi mapiritsi, hpmc amachita ngati thiccener ndi womangika kuti asakhale okhazikika komanso osasinthika.
4.3 Zowonjezera Zakudya
M'makampani azakudya, HPMC imagwira ngati thiccener ndi staterizer, ndipo madzi ake amagwiritsidwa ntchito:
Kuwongolera: Kuyambira pa kusungidwa kwamadzi, hpmc kumatha kusintha kapangidwe ndi kukoma kwa chakudya, kumapangitsa kuti mafuta azikhala ndi mafuta komanso okoma.
Moyo Wokweza: Kudzera mu kusungidwa kwamadzi, HPMC imatha kupewa kutaya madzi nthawi posungirako, potero moyo wa alumali.
4.4 zodzikongoletsera
Mu zodzikongoletsera, kusungidwa kwamadzi kwa HPMC imagwiritsidwa ntchito:
Kunyowa Mphamvu: Monga chinyezi, hpmc chitha kuthandizira kutseka chinyezi pamtunda ndikupereka mphamvu yayitali yonyowa.
Kukhazikitsa kuyimitsidwa: m'malo ndi kuyimitsidwa, hpmc kumalimbitsa malonda ndikulepheretsa stratation ndi storiment.
Kusunga kwamadzi kwa HPMC kumapangitsa kuti ikhale chinthu chofunikira kwambiri m'magawo ambiri. Imakhalanso madzi ndikuchepetsa kusintha kwa madzi kudzera mu holid yolumikizira, mafakisoni apamwamba, kapangidwe ka apaintaneti komanso zotsatira zodzikongoletsera. Kusunga kwamadzi kumakhudzidwa ndi kuchuluka kwa cholowa m'malo mwake, kunenepa kwambiri, kunenepa kwambiri komanso kutentha, komwe kumatsimikizira magwiridwe antchito a HPMC mu pulogalamu inayake. Kaya mukukonzekera zomangira, kukonzekera kwa mankhwala mankhwala, zowonjezera zakudya kapena zodzoladzola, kugwiritsa ntchito madzi ku HPMC kumagwira ntchito yofunika kwambiri pokonza ndi magwiridwe antchito.
