Ubwino wogwiritsa ntchito hydroxypropyl methylcellulose ngati kapisozi yopanda kanthu ndi chiyani?

Izi ndi 2-hydroxypropyl ether methyl cellulose, yomwe ndi mankhwala a semisynthetic. Itha kupangidwa ndi njira ziwiri: (1) Pambuyo pochiza ma linters a thonje kapena ulusi wamtundu wa matabwa ndi koloko, amasakanizidwa ndi chloromethane ndi epoxy Propane amachitira, oyengedwa ndi kupukutidwa kuti atenge; (2) Gwiritsani ntchito kalasi yoyenera ya methyl cellulose pochiza ndi sodium hydroxide, gwirani ndi propylene oxide pansi pa kutentha kwakukulu komanso kuthamanga kwambiri mpaka kufika pamlingo woyenera, ndikuyeretsani. Kulemera kwa mamolekyu kumayambira 10,000 mpaka 1,500,000.

★ Lingaliro loyera lachilengedwe, limakulitsa chimbudzi ndi kuyamwa.

★ Madzi otsika, 5% -8%. Kukana kwamphamvu kwamayamwidwe a chinyezi, zomwe zili mkatimo sizosavuta kuphatikizira, ndipo chipolopolo cha kapisozi sichapafupi kupunduka, kukhala chosalimba, komanso kuuma.

★ Palibe chiwopsezo cholumikizana, palibe kuyanjana, kukhazikika kwapamwamba, popeza hydroxypropyl methylcellulose ndi chochokera ku cellulose, palibe chiwopsezo cha kuphatikizika kwa mapuloteni mu gelatin.

★ Zofunikira zochepa pazosungirako:

Ndi pafupifupi osati Chimaona m'malo otsika chinyezi, ali bwino bata pa kutentha, ndi kapisozi si deform.

★ Miyezo yofananira ndi kuyanjana kwabwino:

Zogwiritsidwa ntchito pamiyezo yapadziko lonse ya pharmacopoeia, mawonekedwe, kukula, mawonekedwe ndi njira yodzaza ndizofanana ndi makapisozi opanda kanthu a gelatin, ndipo palibe chifukwa chosinthira zida ndi magawo.

★ Gwero losakhala la nyama, palibe chiopsezo cha kukula kwa hormone kapena mankhwala otsala m'thupi la nyama.

Hydroxypropyl methylcellulosemakapisozi opanda kanthu amasiyana ndi makapisozi achikhalidwe a gelatin opanda kanthu. Ndi hydroxypropyl methylcellulose (HPMC) yopangidwa ndi zamkati zamatabwa. Kuphatikiza pa ubwino wa lingaliro loyera lachilengedwe, makapisozi opanda kanthu a hydroxypropyl methylcellulose amathanso kupititsa patsogolo mayamwidwe ndi chimbudzi cha mapuloteni, mafuta ndi chakudya, ndipo ali ndi ubwino ndi makhalidwe omwe makapisozi amtundu wa gelatin alibe. Ndi kupititsa patsogolo chidziwitso cha anthu kudzisamalira, chitukuko cha zamasamba, kuthetsa matenda amisala a ng'ombe, matenda a phazi ndi pakamwa pa thanzi la munthu, ndi chikoka cha chipembedzo ndi zinthu zina, mankhwala a capsule achilengedwe ndi zomera. adzakhala kutsogolera kutsogolera kwa chitukuko cha kapisozi makampani. .
