Hydroxypropyl methylcellulose (HPMC) ndi yofunika madzi sungunuka nonionic mapadi efa ndi thickening wabwino, gelling, kugwirizana, filimu kupanga, lubricating, emulsifying ndi kuyimitsa ntchito, choncho chimagwiritsidwa ntchito pomanga zipangizo, mankhwala, chakudya, zodzoladzola ndi zina. .
Kukhuthala kwa hydroxypropyl methylcellulose
Kukhuthala kwa HPMC makamaka kumachokera ku kapangidwe kake ka maselo. Unyolo wa mamolekyulu a HPMC uli ndi magulu a hydroxyl ndi methyl, omwe amatha kupanga zomangira za haidrojeni ndi mamolekyu amadzi, potero amaletsa kuyenda pakati pa mamolekyu amadzi ndikuwonjezera kukhuthala kwa yankho. Pamene HPMC ndi kusungunuka m'madzi, unyolo wake molekyulu chikuchulukirachulukira m'madzi ndi kucheza ndi mamolekyu madzi kupanga dongosolo maukonde, potero kuwonjezera mamasukidwe akayendedwe a yankho. The thickening luso la HPMC amakhudzidwanso ndi zinthu monga mlingo wake m'malo, maselo kulemera ndi ndende.
Kugwiritsa ntchito hydroxypropyl methylcellulose muzomangamanga
Pazomangira, HPMC imagwiritsidwa ntchito kwambiri pazinthu monga matope a simenti, zinthu zopangidwa ndi gypsum ndi zokutira ngati chowonjezera komanso chosungira madzi. Kukula kwake kumatha kupititsa patsogolo ntchito yomanga zinthu ndikuwonjezera ntchito yake yotsutsa-sagging, motero kupangitsa kuti ntchito yomanga ikhale yosavuta. Mwachitsanzo, mumatope a simenti, kuwonjezera kwa HPMC kumatha kukulitsa kukhuthala kwa matope ndikuletsa matope kuti asagwedezeke akamamangidwa pamtunda. Zingathenso kupititsa patsogolo kusungidwa kwa madzi mumatope ndikuletsa matope kuti asaume mofulumira, motero kumapangitsa kuti matopewo akhale olimba komanso olimba.
Kugwiritsa ntchito Hydroxypropyl Methylcellulose mu Pharmaceutical Field
M'munda mankhwala, HPMC chimagwiritsidwa ntchito mapiritsi, makapisozi, gel osakaniza, mankhwala ophthalmic ndi mankhwala ena monga thickener, filimu kale ndi zomatira. Ubwino wake wokhuthala ukhoza kupititsa patsogolo rheological katundu wa mankhwala ndi kusintha bata ndi bioavailability wa mankhwala. Mwachitsanzo, mu ophthalmic kukonzekera HPMC angagwiritsidwe ntchito ngati lubricant ndi thickener, ndi zotsatira zake zabwino thickening akhoza kutalikitsa zokhala nthawi ya mankhwala pa ocular padziko, potero kusintha lapamwamba la mankhwala.
Kugwiritsa ntchito Hydroxypropyl Methylcellulose mu Chakudya
M'makampani azakudya, HPMC imagwiritsidwa ntchito nthawi zambiri muzakudya monga mkaka, ma jellies, zakumwa ndi zophikidwa ngati thickener, emulsifier ndi stabilizer. Zake thickening tingati kusintha kukoma ndi kapangidwe chakudya, ndi kuonjezera mamasukidwe akayendedwe ndi bata la chakudya. Mwachitsanzo, mu mkaka, HPMC akhoza kuonjezera mamasukidwe akayendedwe a mankhwala ndi kupewa whey mpweya, potero kusintha kukoma ndi bata la mankhwala.
Kugwiritsa ntchito Hydroxypropyl Methylcellulose mu Zodzoladzola
M'munda wa zodzoladzola, HPMC chimagwiritsidwa ntchito mankhwala monga mafuta odzola, creams, shampu ndi zoziziritsa kukhosi monga thickener, emulsifier ndi stabilizer. Kukhuthala kwake kumatha kusintha mawonekedwe ndi kukhazikika kwa zodzoladzola, ndikuwongolera magwiridwe antchito komanso chidziwitso cha ogula. Mwachitsanzo, mu zodzoladzola ndi zonona, kuwonjezera kwa HPMC kumatha kukulitsa kukhuthala kwa mankhwalawa, kupangitsa kuti ikhale yosavuta kugwiritsa ntchito ndikuyamwa, komanso kuwongolera kukhathamiritsa kwa mankhwalawa.
Hydroxypropyl Methylcellulose yakhala ikugwiritsidwa ntchito kwambiri muzomangamanga, mankhwala, zakudya ndi zodzoladzola chifukwa cha kukhuthala kwake kwakukulu. Kukula kwake kumapangidwira makamaka kuonjezera kukhuthala kwa yankho mwa kupanga ma hydrogen bond ndi mamolekyu amadzi, kuletsa kuyenda kwa mamolekyu amadzi. Magawo osiyanasiyana ali ndi zofunikira zosiyanasiyana zogwiritsira ntchito HPMC, koma ntchito yake yayikulu ndikuwongolera kukhuthala komanso kukhazikika kwazinthuzo. Ndi kupita patsogolo kwa sayansi ndi ukadaulo komanso chitukuko chosalekeza chaukadaulo wogwiritsa ntchito, chiyembekezo chogwiritsa ntchito HPMC chidzakhala chokulirapo.
