Hydroxypropyl methylcellulose (hpmc) ndi polimmer yosiyanasiyana yomwe imapeza ntchito zambiri pamakampani osiyanasiyana, kuphatikizapo za mankhwala ogulitsa, kuphatikiza, zodzola, zodzoladzola. Malo ake apadera amapangitsa kuti zikhale zofunikira pakupanga kusintha kwa magazi, mafilimu, kumanga, ndi kupititsa patsogolo. Kuzindikira kapangidwe kake, kapangidwe kake, katundu, kugwiritsa ntchito kwa HPMC ndikofunikira pakugwiritsa ntchito kwake kothandiza.
1.Kuchotsa kwa HPMC
HPMC ndi poldemer polymer yopangidwa kuchokera ku cellulose, polysacchacide mwachilengedwe imapezeka m'makoma a cell a mbewu. Njira yopanga imathandizira kuchitira cellulose ndi alkali kuti apange alkali kuti apange cellulose, kutsatiridwa ndi ma pureen Oxide ndi methyl chloride. Kusintha kwamankhwala kumeneku kumabweretsa kuyambitsa kwa hydroxypropyl ndi methoxy m'malo mwa msana wa cellulose, kutuluka kwa HPMC.
Mulingo wa zolowetsa (DS) wa hydroxypyl ndi methoxy magulu a HPMC, kuphatikizapo kusungunuka, kuphatikizapo kususuka, khwala, ndi mawonekedwe opanga filimu. Nthawi zambiri, ma gpmc masukulu okhala ndi zinthu zapamwamba amawonetsa kusungunuka mosungunuka m'madzi ndi kukulitsa.
2.properies a hpmc
Madzi osungunuka: hpmc amasungunuka m'madzi ozizira, ndikupanga zomveka, ma viscous. Kusungunuka kumatha kupangika ndikusintha kuchuluka kwa kulowetsa, kunenepa kwambiri, ndi kutentha.
Mapangidwe a filimu: hpmc amatha kupanga mafilimu osinthika komanso owoneka bwino atayanika. Makanema awa ali ndi katundu wabwino kwambiri, ndikuwapangitsa kukhala oyenera kugwiritsa ntchito makampani opanga mankhwala ndi mafakitale.
Kusintha kwa Vission: HPMC imawonetsa machitidwe a pseudoplactic, momwe ma viscy amachepetsa ndikuwonjezeka. Katunduyu amagwiritsidwa ntchito mosiyanasiyana kuti athetse mayendedwe ndi zinthu zoyipa.
Kukhazikika kwamafuta: HPMC imawonetsa kukhazikika pamtunda wambiri, ndikupangitsa kukhala koyenera kugwiritsa ntchito magwiridwe ofunikira kutentha kapena kuwonekera kutentha kwa kutentha.
Mankhwala osagwirizana: hpmc ndikugwirizana, chogwirizana ndi zowonjezera zosiyanasiyana, zomwe zimangochita, ndi zosakaniza zogwiritsidwa ntchito zomwe zimagwiritsidwa ntchito nthawi zambiri zomwe zimagwiritsidwa ntchito mu mankhwala ogulitsa ndi zakudya.
3.Synthesis a hpmc
Kaphatikizidwe wa HPMC imaphatikizapo njira zingapo:
Chithandizo cha alkali: Cellulose imathandizidwa ndi alkali, monga sodium hydroxide, kuti apange cellulose.
Kusintha: Alkalini cellulose yachitika ndi ma propyne oxide kuti ayambitse magulu a hydroxypyl pa celluulose msana.
Methylat: The Hydroxypropropropropyselt cellose imagwiritsidwanso ntchito ndi methyl chloride kuti iyambitse magulu a meoxy, opereka hpmc.
Kuyeretsa: HPMC yomwe imatsukidwa imatsukidwa kuti ichotse zopangidwa ndi zinthu ndi zosayera, ndikuonetsetsa kuti zinthu ziziyenda bwino.
4.PapPerctictions ya HPMC
Makampani ogulitsa mankhwala: HPMC imagwiritsidwa ntchito kwambiri ngati mankhwala ophatikizika mu piritsi, pomwe imakhala ngati bander, kusazindikira, ndi kuwongolera. Amagwiranso ntchito mu ophthalmic njira zothetsera zowonjezera, zowoneka bwino kwambiri, ndi kuyimitsidwa pakamwa chifukwa cha kusakhazikika kwake komanso kosungirako.
Makampani Ogulitsa Chakudya: Makampani ogulitsa zakudya, hpmc amakhala ngati thickir, okhazikika, ndi emulsifier, kuphatikiza zisungunuke, kuphatikizapo mavakela, komanso mkaka. Amagwiritsidwanso ntchito kuphika kwa gluten ngati wothandizila kuphatikizika ndi chinyezi chowonjezera.
Makampani omanga: HPMC ndiowonjezera matope a simenti, mazira, ndi tiles. Imathandizanso kugwira ntchito, kusungidwa kwamadzi, ndi kutsatira, kumathandizira pa ntchito yonse yomanga.
Zogulitsa Zaumwini: HPMC imaphatikizidwa mu zodzikongoletsera, zopangidwa ndi skincare, ndi njira zosamalira tsitsi kuti mawonekedwe ake, akukula, ndi emulsideni. Imapereka mawonekedwe abwino, kukhazikika, ndi malingaliro owoneka bwino ku zodzola, mafuta, ndi ma gels.
Kuphimba ndi Kulemba: Zovala za HPMCizi zimagwiritsidwa ntchito pazitsulo ndi makapisozi kuti asinthane, kukoma kwa chigoba, ndikuteteza chinyontho. Makanema a HPMC amagwiritsidwanso ntchito pazakudya za chakudya monga zokutira kapena zotchinga zotsutsana ndi chinyezi komanso mpweya.
Hydroxypypyl methylcellulose (hpmc) ndi polymer yolimbana ndi mapulogalamu osiyanasiyana mafakitale. Kuphatikiza kwake kwapadera kwa katundu, kuphatikizapo kusungunuka kwamadzi, mapangidwe filimu, kusinthidwa kwa mavidiyo, ndi kusamvana kwamankhwala, kumapangitsa kuti zikhale zofunikira m'mankhwala, chakudya, ndi zinthu zosamalira pandekha. Kumvetsetsa kapangidwe, kaphatikizidwe, katundu, kugwiritsa ntchito kwa HPMC ndikofunikira kwa opanga ndi opanga kufunafuna phindu lake muzomera ndi zatsopano.
Kufunikira kwa HPMC kuli mu kusintha kwake, magwiridwe antchito, komanso zopereka kuti zithandizire magwiridwe antchito, kukhazikika, komanso malingaliro owoneka bwino a zinthu zosiyanasiyana m'magawo osiyanasiyana, ndikupanga mawonekedwe amtengo wapatali m'magawo amakono komanso mapulogalamu.
