Hydroxypropyl methylcellulose (HPMC) si plasticizer mwachikhalidwe.Ndiwochokera ku cellulose yomwe imagwiritsidwa ntchito kwambiri m'mafakitale azamankhwala, chakudya, zomangamanga komanso chisamaliro chamunthu.Ngakhale sizikhala ngati mapulasitiki omwe amagwiritsidwa ntchito mu ma polima, amawonetsa zinthu zina zomwe zingafanane ndi zotsatira za pulasitiki muzinthu zina.
Kuti tifufuze bwino mutu wa HPMC ndi gawo lake m'mafakitale osiyanasiyana, titha kuyang'ana momwe amapangira mankhwala, mawonekedwe ake, momwe amagwiritsidwira ntchito, komanso zabwino ndi zovuta zake.Kumvetsetsa bwino kwa HPMC kudzapereka chidziwitso pamagwiritsidwe ake osiyanasiyana komanso chifukwa chake imatengedwa kuti ndi yofunika kwambiri pamapangidwe ambiri.
Kapangidwe ka mankhwala ndi katundu wa HPMC
Kapangidwe ka Chemical:
HPMC ndi semi-synthetic polima yochokera ku cellulose, polima wachilengedwe wopezeka m'makoma a cellulose.Magulu a Hydroxypropyl ndi methyl amayambitsidwa kudzera mukusintha kwamankhwala.Kusintha kumeneku kumasintha mawonekedwe a thupi ndi mankhwala a cellulose, zomwe zimapangitsa kuti pakhale zophatikiza ndi magwiridwe antchito.
chikhalidwe:
Hydrophilic: HPMC ndi yosungunuka m'madzi komanso ya hygroscopic kwambiri, ndikupangitsa kuti ikhale yoyenera pamitundu yosiyanasiyana yomwe imafunikira kusungidwa kwamadzi kapena kumasulidwa koyendetsedwa.
Kupanga mafilimu: Lili ndi zinthu zopanga mafilimu zomwe zimapanga filimu yotetezera ikagwiritsidwa ntchito pamwamba, zomwe zimapangitsa kuti zikhale zothandiza popaka mankhwala ndi zomangira.
Thickening wothandizira: HPMC nthawi zambiri amagwiritsidwa ntchito ngati thickening wothandizira munjira zamadzimadzi.Ake mamasukidwe akayendedwe kumawonjezera ndi ndende, kulola kulamulira kugwirizana kwa madzi formulations.
Kutentha kwa kutentha: Magiredi ena a HPMC ndi osinthika, kutanthauza kuti amatha kusintha magawo osinthika ndikusintha kwa kutentha.
Kugwiritsa ntchito HPMC m'mafakitale osiyanasiyana
1. Makampani opanga mankhwala:
Kupaka Mapiritsi: HPMC imagwiritsidwa ntchito ngati zokutira pamapiritsi amakampani opanga mankhwala.Amapereka chitetezo chokwanira, amawongolera kutulutsidwa kwa mankhwala, ndikuwongolera mawonekedwe a piritsi.
Mayankho a Ophthalmic: Mu madontho a maso ndi njira zamaso, HPMC imatha kukulitsa kukhuthala ndikuwongolera nthawi yosungira pamalo owonekera.
2. Makampani azakudya:
Thickening wothandizira: HPMC amagwiritsidwa ntchito ngati thickening wothandizira zakudya zosiyanasiyana, kuphatikizapo sauces, soups ndi mkaka.
Emulsifier: Muzinthu zina zazakudya, HPMC imatha kukhala ngati emulsifier, kuwongolera kukhazikika kwa emulsion.
3. Makampani omanga:
Zomatira pa matailosi: Kuphatikizika kwa HPMC pa zomatira matailosi kumawongolera magwiridwe antchito, kusunga madzi komanso kulimba kwa ma bond.
Mitondo ndi Pulasita: Amagwiritsidwa ntchito m'zinthu zomangira monga matope ndi mapulasitala kuti azitha kumamatira komanso kugwira ntchito bwino.
4. Zothandizira pawekha:
Mapangidwe apamutu: Mu zodzoladzola, zodzoladzola ndi zina zapamutu, HPMC imathandizira kukonza mawonekedwe, kukhazikika komanso kumverera kwa khungu kwa mankhwalawa.
Zosamalira Tsitsi: HPMC imapezeka muzinthu zina zosamalira tsitsi chifukwa cha mawonekedwe ake opangira mafilimu ndi kuwongolera.
Ubwino ndi Kuipa kwa HPMC
ubwino:
Biocompatibility: HPMC nthawi zambiri imawonedwa ngati yotetezeka kuti anthu amwe ndipo imagwiritsidwa ntchito kwambiri pazamankhwala ndi zakudya.
Kusinthasintha: Ili ndi katundu wosiyanasiyana ndipo ndi yoyenera kwa mafakitale osiyanasiyana ndi mapangidwe.
Kusunga Madzi: Mtundu wa hydrophilic wa HPMC umathandizira kusunga madzi, zomwe zingakhale zopindulitsa pazinthu zina.
zoperewera:
Mtengo: HPMC ikhoza kukhala yokwera mtengo poyerekeza ndi zina zowonjezera.
Kutengeka kwa Kutentha: Chifukwa cha kusinthika kwa magiredi ena a HPMC, mapangidwe ena amatha kukhudzidwa ndi kusintha kwa kutentha.
Pomaliza
Ngakhale HPMC si plasticizer mwachikhalidwe, katundu wake wapadera zimapangitsa kuti ikhale yofunika kwambiri m'mafakitale osiyanasiyana.Imawonetsa kusinthasintha kwake monga filimu yakale, yowonjezera komanso yosungira madzi muzamankhwala, chakudya, zomangamanga ndi ntchito zothandizira anthu.Kumvetsetsa kapangidwe ka mankhwala, katundu, ndi kagwiritsidwe ntchito ka HPMC ndikofunikira kwa opanga ma formula ndi ofufuza omwe akufuna kukhathamiritsa makonzedwe kuti akwaniritse zosowa zenizeni.Ubwino wa biocompatibility ndi kusinthasintha kumaposa zovuta zomwe zingatheke, kupangitsa HPMC kukhala chisankho chodziwika bwino m'mafakitale ambiri.
