Kodi ubwino wogwiritsa ntchito hydroxypropyl methylcellulose ngati kapisozi yopanda kanthu ndi wotani?

Katunduyu ndi wa 2-hydroxypropyl ether methyl cellulose, yomwe ndi mankhwala opangidwa pang'ono. Ikhoza kupangidwa m'njira ziwiri: (1) Pambuyo pochiza thonje kapena ulusi wa matabwa ndi caustic soda, amasakanizidwa ndi chloromethane ndi epoxy. Propane imachitapo kanthu, kukonzedwa ndikupukutidwa kuti ipezeke; (2) Gwiritsani ntchito methyl cellulose yoyenera kuti muchiritse ndi sodium hydroxide, chitapo kanthu ndi propylene oxide pansi pa kutentha kwakukulu ndi kupanikizika kwakukulu kufika pamlingo woyenera, ndikuchiyeretsa. Kulemera kwa mamolekyulu kumakhala kuyambira 10,000 mpaka 1,500,000.

★ Lingaliro lachilengedwe loyera, limathandizira kugaya chakudya ndi kuyamwa kwake.

★ Madzi ochepa, 5%-8%. Kukana kwambiri kuyamwa kwa chinyezi, zomwe zili mkati mwake sizimavuta kusonkhana, ndipo chipolopolo cha kapisozi sichimavuta kuchisintha, kuchiphwanyika, ndi kuchilimbitsa.

★ Palibe chiopsezo cha cross-linking reaction, palibe kuyanjana, pali kukhazikika kwakukulu, popeza hydroxypropyl methylcellulose ndi yochokera ku cellulose, palibe chiopsezo cha cross-linking reaction ya zinthu za mapuloteni mu gelatin.

★ Zofunikira zochepa pakusungira:

Sichimaphwanyika kwambiri m'malo opanda chinyezi, chimakhala chokhazikika bwino kutentha kwambiri, ndipo kapisoziyo siimasintha mawonekedwe.

★ Miyezo yofanana komanso kugwirizana bwino:

Potsatira miyezo ya dziko lonse ya pharmacopoeia, mawonekedwe, kukula, mawonekedwe, ndi njira yodzazira ndi zofanana ndi makapisozi opanda kanthu a gelatin, ndipo palibe chifukwa chosinthira zida ndi zida zina.

★ Chochokera ku nyama, palibe chiopsezo cha kukula kwa mahomoni kapena mankhwala m'thupi la nyama.

Hydroxypropyl methylcelluloseMakapisozi opanda kanthu ndi osiyana ndi makapisozi opanda kanthu a gelatin. Ndi hydroxypropyl methylcellulose (HPMC) opangidwa ndi zamkati zamatabwa. Kuphatikiza pa ubwino wa lingaliro lachilengedwe loyera, makapisozi opanda kanthu a hydroxypropyl methylcellulose amathanso kukonza kuyamwa ndi kugaya mapuloteni, mafuta ndi chakudya, ndipo ali ndi zabwino ndi makhalidwe omwe makapisozi opanda kanthu a gelatin achikhalidwe alibe. Ndi kupititsa patsogolo chidziwitso cha anthu chodzisamalira, chitukuko cha kudya nyama, kuthetsa matenda amisala a ng'ombe, matenda a mapazi ndi pakamwa pa thanzi la anthu, komanso mphamvu ya chipembedzo ndi zina, zinthu zachilengedwe komanso zopangidwa ndi zomera zidzakhala njira yotsogola pakukula kwa makampani a makapisozi.
