Kodi mawu abwino kwambiri a hydroxypropyll methylcelulose?

Hydroxypypyl methylcellulose (HPMC) imagwiritsidwa ntchito polymer polymer omwe amagwiritsidwa ntchito kwambiri m'mankhwala, zodzoladzola, chakudya ndi zomanga. HPMC ili ndi ntchito zoyendetsera mamasukidwe, kulimbitsa emulsions, kukonza zinthu zachinyengo ndikukula, kotero kuti mafayilo ndi gawo lofunikira pakugwiritsa ntchito.

1. Makhalidwe a Vicconce a HPMC
Makulidwe a HPMC amagwirizana kwambiri ndi kulemera kwake kwa ma celecular, digiri ya kulowetsedwa (mwachitsanzo, kuchuluka kwa miniti yolowa m'malo a hydroxypyl ndi methyl), yankho lina. Nthawi zambiri, chokulirapo kunenepa, mafayilo a HPMC. Kuphatikiza apo, njira zothetsera HPMC yokhala ndi gawo lalikulu la cholowa chimakhala ndi mamasukidwe apamwamba chifukwa kuchuluka kwazolowa kumakhudza kapangidwe kake kanyolo, zomwe zimakhudza kusungunuka kwake ndikusintha mapangidwe ake.

Makulidwe a HPMC nthawi zambiri amayesedwa pamlingo wina wometa ubweya pogwiritsa ntchito wotchire yozungulira. Kutengera ndi kugwiritsa ntchito HPMC, mtengo wofunikira Viscty ndiwosiyananso.

2. Zofunikira kwa HPMC Solcson pamapulogalamu osiyanasiyana
Phunziro la pharmaceutical
M'makampani opanga mankhwala, hpmc nthawi zambiri amagwiritsidwa ntchito kukonza mapiritsi, makapisozi, madontho amaso ndi mankhwala omasulidwa-amasulidwa. Pokonzekera mapiritsi ndi makapisozi, hpmc imagwira ntchito yofunika kwambiri pakuwongolera mankhwala monga kanema wakale ndi wolima.

Kumasulira Kukonzekera kwa Makompyuta: Kukonzekera mankhwala omasulira kumafunikira HPMC kukhala ndi mawonekedwe owoneka bwino. Nthawi zambiri, mafayilo a njira ya HPMC ayenera kuwongoleredwa pakati pa 300 ndi 2000 mappa mbible, omwe amathandizira kumasulidwa kwa mankhwalawa. Ngati mafayilo ali okwera kwambiri, mankhwalawa amatha kumasulidwa pang'onopang'ono; Mawonekedwe ake ndi otsika kwambiri, amatulutsa mawu oyenera kugwiritsa ntchito mankhwalawa.

Piritsi Kukamba: Pafupipafupi patebulo, mamasukidwe a HPMC ali ndi mphamvu yofunika pa tebulo la piritsi la piritsi komanso kusamwa. Pakadali pano, mafalowo ayenera kukhala pakati pa 500 ndi 1500 Ropland kuti atsimikizire zomatira bwino komanso kugwirira koyenera.

Gawo la chakudya
Mu makampani ogulitsa zakudya, hpmc nthawi zambiri amagwiritsidwa ntchito ngati thiccener ndi emulsifier mu zinthu monga zokometsera, ayisikilimu, ndi madzi a zipatso zipatso. Zinthu zosiyanasiyana zimakhala ndi zofunikira zosiyanasiyana pakukweza kwa HPMC:

Kumwa kwa Mafuta: Mumwazi wa zipatso madzi akumwa, mafayilo a HPMC ayenera kuyang'aniridwa pakati pa 50 ndi 300 a MPPI · 300. Mafayilo apamwamba kwambiri angapangitse kuti mphezi zilawe zandiweyani, zomwe sizikugwirizana ndi zomwe amagula.

Ayisikilimu: pa ayisikilimu, hpmc amagwiritsidwa ntchito kukonza mawonekedwe ndi kusalala kwake. Pakadali pano, mtengo wamaso umafunika kuwongolera pakati pa 150 ndi 1000 mateyo kuti atsimikizire kuti ayisikilimu ali ndi kusasinthika koyenera komanso lilime labwino kumamverera.

Gawo Lomanga
Mu makampani omanga, hpmc nthawi zambiri amagwiritsidwa ntchito pomanga zida monga simenti, gypsum ndi matope. Udindo wa HPMC mu zinthuzi makamaka kuti zitheke ndikusintha madzimadzi. Kukula kwake nthawi zambiri kumakhala kochulukirapo, nthawi zambiri ma Rouch 2000 mpaka 10000. HPMC M'mitundu iyi imatha kusintha magwiridwe antchito omanga, monga kukonza mwayi wotsegulira ndikuwonjezera nthawi yotseguka.

Munda Wodzikongoletsa
Mu gawo lodzikongoletsera, hpmc nthawi zambiri limagwiritsidwa ntchito popanga zinthu monga zotupa, mafuta, shamsus, makamaka. Mafayilo apamwamba kwambiri angayambitse kugwiritsa ntchito malonda, akukhudzanso ogwiritsa ntchito.

3. Zinthu zomwe zikukhudza mafayilo a HPMC
Kulemera kwa maselo: Kukulira kwakukulu kwa HPMC, kutalika kwa ma molecular, komanso mafayilo a yankho. Kwa HPMC yokhala ndi kulemera kwakukulu, mafayilo a yankho limodzi kukhazikika kwambiri kudzakhala kokulirapo kuposa momwe Hpmc yochepetsetsa yochepetsetsa. Chifukwa chake, kusankha HPMC yokhala ndi kulemera koyenera ndikofunikira kuti muwongolere mamasukidwe.

Madigirimu a zolowa: Mlingo wa mu HPMC, ndiye kuti, mulingo wa zolowetsa za hydroxypypyl ndi methyl, chidzakhudza mafayilo ake. Mulingo wapamwamba kwambiri womwe umalowa m'malo mwake umapangitsa ma molekyulu a HPMC kukhala khola, komanso kulumikizana pakati pa mamolekyules kumawonjezeka, zomwe zimapangitsa kuti zikuwonjezereka.

Njira Yothetsera: Kutengera kwa HPMC kuli ndi mphamvu kwambiri pa mafayilo. Kukhazikika kotsika, mafayilo a HPMC yankho la HPMC ndi lotsika; Pazinthu zambiri, kuyanjana pakati pa mambo kwamiyendo kumakulitsidwa, ndipo ma utoto amawonjezeka kwambiri. Chifukwa chake, m'mapulogalamu othandiza, mafayilo omaliza amatha kuwongoleredwa ndikusintha kuchuluka kwa HPMC.

Ma sol sol solformant ndi chilengedwe: kusungunuka ndi ufa wa HPMC imagwirizana kwambiri ndi mtundu wa zosungunulira ndi chilengedwe (monga pH, ndi zina). Zosiyanasiyana komanso kutentha kosiyanasiyana ndi ma ph kumasintha kusungunuka kwa HPMC, potengera mafayilo yankho lake.

Makulidwe a HPMC ndi amodzi mwa magawo ofunikira pakufunsira m'minda yosiyanasiyana. Mu mankhwala opangira mankhwala, chakudya, zomangamanga ndi mafakitale ena, mamasukidwe a HPMC iyenera kuyang'aniridwa munthawi yayitali malinga ndi zofunikira zosiyanasiyana. Posintha zinthu monga kulemera kwa maselo, kuchuluka kwa kulowetsedwa, kukhazikika kwa HPMC, ma visction atha kuwongolera kuti akwaniritse zosowa zosiyanasiyana. Muzopanga zenizeni, kutsatsa ma vinyayo kuti mupeze zofunikira pa ntchito ndi njira yotsimikizira kuti ntchito ndi magwiridwe antchito.
