Hydroxypypyl methylcellulose (hpmc) ndi nkhani yofunika yomwe ili ndi mapulogalamu angapo opanga mafakitale komanso mafakitale ena monga chakudya, zodzoladzola komanso zomangamanga. Kufunika kwa HPMC kwakhala kukukula mokhazikika pazaka chifukwa chazomwe amapanga zapadera monga kukula, kumanga, kupanga mafilimu komanso kusungidwa kwamadzi. Munkhaniyi, tikambirana njira yopangira ma hydroxypypyl a methylcellulose (hpmc).
Njira yopangira ma hydroxypypyl wa methylcellulose (hpmc) ndi njira yomwe cellulose imakumana ndi Propylene oxide ndi methyl chloride pamaso pa alkali. Njira zimachitika pansi pa kutentha, kukakamizidwa ndi nthawi yolamulidwa kuti ipange zinthu zapamwamba za HPMC.
Gawo loyamba popanga hpmc pogwiritsa ntchito njira yopanga alkaline yopanga ndi kukonza ma cellulose. Cellulose imayeretsedwa koyamba pochotsa zodetsa zilizonse ndipo kenako zimasinthidwa kukhala alkali cellulose pogwiritsa ntchito alkali monga sodium hydroxide. Izi ndizovuta chifukwa zimachulukitsa kufupikitsa kwa cellulose ndi ma reagents omwe amagwiritsidwa ntchito motsatira.
Chalkali cellulose amathandizidwa ndi chisakanizo cha prosylen oxide ndi methyl chloride pansi pa kutentha ndi kukakamizidwa. Zomwe zimachitika pakati pa alkali cellulose ndi zotsatirapo zomwe zimapangitsa kupanga chinthu, zomwe ndi osakaniza a hydroxypropyll meth methylcellulose ndi zinthu zina.
Osakaniza amasambitsidwa, osalowerera ndale komanso osefedwa kuti achotse zodetsa monga zosakira komanso zopangidwa ndi zinthu. Njira yothetsera vutoli imakhazikikanso ndikusinthasintha kuti mupeze zoyera zambiri za HPMC.
Njira yopangira ma hydroxypypyl wa methylcellulose (hpmc) ali ndi zabwino zambiri poyerekeza ndi njira zina zopangira monga momwe akupezera. Chimodzi mwa zabwino ndichakuti ndi njira yachilengedwe. Mosiyana ndi njira zina, njira yopangira malkali imagwiritsa ntchito ma solgeenated ma sol solgeenative zilengedwe ndi thanzi la anthu.
Ubwino wina wa njirayi ndikupanga zinthu zapamwamba za HPMC. Zoyendetsedwa Zomwe Zimayendetsedwa Zotsimikizika Zogulitsa ndizosasinthika komanso zoyenera kugwiritsa ntchito mitundu yosiyanasiyana.
Kugwiritsa ntchito HPMC mu malonda ogulitsa mankhwala ndikofunikira pakupanga mapiritsi, makapisozi ndi mitundu ina ya mankhwala. HPMC itha kugwiritsidwa ntchito ngati binder, disctigragragragragragragragragragragragragragragragragragrance, enc. Kugwiritsa ntchito HPMC mu mapulogalamu awa onetsetsani kuti mawonekedwe apamwamba ndikukwaniritsa mfundo zofunika.
HPMC imagwiritsidwanso ntchito ngati thicker, emulsifier ndi okhazikika m'makampani azakudya. Kugwiritsa ntchito HPMC muzakudya kumapangitsa kuti mitundu yosiyanasiyana ikhale yofanana, mafakisoni ndi abwino.
Mu makampani omanga, hpmc imagwiritsidwa ntchito ngati chowonjezera cha simenti kuti muthandize kugwirira ntchito, kusungidwa kwamadzi komanso ndalama zogwirizira simenti. Kugwiritsa ntchito HPMC kumatsimikizira kuti zomangamanga ndizothandiza kwambiri ndikukwaniritsa mfundo zofunika.
Mwachidule, njira yopangira alkali yopanga hydroxypyl ya methylcellulose (hpmc) ndi njira yopanga zinthu zapamwamba za HPMC ndipo zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana monga mankhwala opangira mafarma, chakudya, ndi zomanga. Kugwiritsa ntchito HPMC mu mapulogalamuwa kumatsimikizira kuti malonda ndi apamwamba kwambiri ndipo amakwaniritsa mfundo zofunika. Njira iyi yopanga izi imakhalanso yokomera ndipo imapanga zoyera kwambiri za HPMC.
