Hydroxypropyll Methylcellulose (HPMC) imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana kuphatikiza ntchito yomanga m'malo mwake. Pamunda wa kupanga, HPMC imachita mbali yofunika kwambiri posintha zinthu monga kugwira ntchito zomanga, kutsatira, kusungidwa, kusungidwa kwamadzi komanso kusokonekera kwa madzi.
Phiri ndi zinthu zomwe zimagwiritsidwa ntchito kwambiri pomanga kuti mudzaze ming'alu, pamlingo wapamwamba ndikuyika malo osalala pamakoma ndi kudekha. Kugwiritsa ntchito bwino ndikofunikira kuti mukwaniritse zotsatira zomwe mukufuna pantchito yomanga, motero zowonjezera zimagwiritsidwa ntchito polimbikitsa katundu wake. Hydroxypylfellllulose (hpmc).
1. Mwachidule za hydroxypropyl methylcellulose (hpmc):
HPMC imachokera ku cellulose, zopangidwa ndi magulu a hydroxyl a cellulose ndi methoxy ndi hydroxypyl magulu. Kusintha kwamankhwala kumeneku kumapereka katundu wapadera wa HPMC, kupangitsa kusungunuka kwambiri m'madzi ndikutha kupanga zothetsera zokhazikika za Colloidal. M'malo mwa kupanga, hpmc amachita ngati thiccener, binder, ndi wothandizira madzi, zomwe zimakhudza zatsopano ndi kuuma katundu wa paten.
Malangizo a 2.
Kuphatikizira HPMC ku Mafuta a Ppmc kumafunikira kuganizira zinthu mosamalitsa monga tinthu tambiri tating'onoting'ono, zifunike zam'magazi, mutakhala ndi nthawi, komanso kuphatikizira ndi zina zowonjezera. Kusankha gawo loyenerera kwa HPMC ndipo ndende ndizofunikira kukwaniritsa njira yabwino pakati pa kusasamala komanso makina. Kuphatikiza apo, kulumikizana pakati pa HPMC ndi zosakaniza zina monga mafayilo, utoto, ndi zodetsa, ziyenera kuyesedwa kuti zitsimikizidwe kuti mukugwirizana ndikutha kugwira ntchito.
3. Zokhudza Kuchita Kuchita:
Chimodzi mwazodali zabwino za HPMC mu purtems ndikutha kuwongolera kugwira ntchito posintha miyambo yamitundu. HPMC imagwira ngati thickener, kuwonjezera mamasukidwe a putty phala ndikuchepetsa kusamba kapena kuwuluka pa nthawi ya ntchito. Mphamvu ya Pseudoplasticasticasties ya HPMC yowonjezera yowonjezera kufalitsa mosavuta komanso kutsiriza kosalala kwa putty pamtunda, motero kukulitsa kugwirira ntchito ndi ntchito yogwirira ntchito mosiyanasiyana.
4. Zovuta pa makina:
Kuphatikiza kwa HPMC kumatha kukhudza kwambiri mphamvu zamakina, kuphatikizapo zotsatsa mphamvu, mphamvu zakuthwa komanso kuthekera bwino. HPMC imapanga filimu yopyapyala pamwamba pa tinthu tating'onoting'ono tosiyanasiyana, zomwe zimachita zomatira ndikusintha zomatira pakati pa tinthu. Izi zimawonjezera coutheon mkati mwa matchesi ndikuwonjezera kukana kusokoneza ndi kusokoneza. Kuphatikiza apo, hpmc imathandizira kupanga micropturtuction yowonda, potengera mphamvu zamakina monga mphamvu zopsinjika ndi kuvala kukana.
5.
Kukhazikika ndi gawo lalikulu la magwiridwe antchito, makamaka pakugwiritsa ntchito panja komwe kumapangitsa kuti chinyezi, ma radiation a UV, UV Kusinthasintha ndi kutentha kumatha kusokoneza ntchitoyo pakapita nthawi. HPMC imagwira ntchito yofunika kwambiri yolimbikitsidwa kukhazikika pofuna kukonza madzi kukana kukula, kukana ndi kukana microsi yaying'ono. The hydrophilic chilengedwe cha HPMC imalola kusunga chinyontho mu matchet matrix, kupewa kudzipha komanso kuchepetsa chiopsezo cha ming'alu ya smira. Kuphatikiza apo, HPMC imapanga filimu yoteteza pamtunda wa putty, zomwe zimalepheretsa chinyezi kulowa mu kulowa ndi kuukira kwa mankhwala, mwakutero ndikupatsa moyo wa ntchito yankhondo.
6. Maganizo a chilengedwe:
M'zaka zaposachedwa, pamakhala chidwi chokula ndikupanga zida zomanga zachilengedwe zomwe zimachepetsa mphamvu zachilengedwe. HPMC imapereka zabwino zambiri pankhaniyi, chifukwa zimachokera ku zinthu zokonzanso ndipo ndizothandiza m'malo abwino. Chifukwa chake, kugwiritsa ntchito kwa HPMC mu purtems kumawonjezera zinthu zakuthupi kumawonjezera mphamvu, motero kumachepetsa kuwononga mphamvu ndi zinthu zina. Komabe, moyo wonse wozungulira wa punty wokhala ndi HPMC, kuphatikizapo zinthu monga kupanga njira, mayendedwe ndi kutaya, ayenera kupendedwa, kuyenera kuwunika kuti muwunike bwino.
Hydroxypylm methylcellulose (hpmc) ndi zowonjezera zambiri zomwe zingakhudze kwambiri magwiridwe antchito pomanga. Kutha kwa HPMC kutsanzira nyama, kusintha mphamvu, kumathandizira magetsi ndikusintha kulimba kumathandizira kukula kwa mapangidwe apamwamba kwambiri oyenera. Komabe, kukwaniritsa momwe mungagwiritsire ntchito bwino kumafunikira kusankha mosamala, kuganizira zinthu monga kusankha kwa kade kalasi, kugwirizana ndi zachilengedwe. Kafukufuku wina amafunikira kuti mufufuze ntchito zatsopano za hpmc m'mapangidwe a HPMC mumitundu yovuta popanga zolimbitsa zokhazikika.
