Kusiyana pakati pa hydroxypropyl methylcellulose ndi hydroxethyl cellulose

Hydroxypropyl methylcellulose (hpmc)ndiHydroxyethyl cellulose (hec)ndi awiri omwe amagwiritsidwa ntchito kawirikawiri kawirikawiri. Amagwiritsidwa ntchito kwambiri pomanga, mankhwala opangira mankhwala, zodzoladzola, chakudya ndi mafakitale ena chifukwa cha zinthu zawo zapadera komanso kugwiritsa ntchito malo awo. Ngakhale onse ndi zida zosungunulira madzi osungunuka kuchokera ku cellulose wachilengedwe, pali kusiyana kodziwikiratu pakati pa awiriwa mankhwala, magwiridwe antchito ndi magawo ogwiritsira ntchito.

1. Kusiyana kwa kapangidwe ka mankhwala

Hpmc (hydroxypropyl methylcellulose)

Ndiwosagwiritsa ntchito cellulose yopanda ionic ethel eyal yomwe idapezeka ndi cellulose ndi methanol ndi ma propyle oxide atatha kupuma. Kupanga kwake molecular kuli ndi methoxy (-Och3) ndi hydroxypropoxy (-ch2chohch3) m'malo otetezedwa. Mlingo wambiri wa HPMC ikhoza kusinthidwa malinga ndi kugwiritsa ntchito kosiyanasiyana.

Hec (hydroxyethyl cellulose)

Ndi mankhwala omwe amapezeka ndi ma cellulose omwe ali ndi ethylene oxide pambuyo pa kupembedza, ndipo mawonekedwe ake molecular muli ma hydroxyethyl (-ch2ch2oh. Hec ndi ma ether osakhazikika a celluose, ndipo kuchuluka kwake kwa chikondwerero kungasinthenso malinga ndi zosowa zenizeni.

2. Kusiyana kwa magwiridwe antchito

Kusalola

Kimacell®hpmc imatha kusungunuka mwachangu m'madzi ozizira kuti apange njira yowonekera kapena yopanda ma visy, yomwe imalimbana ndi kutentha kwambiri. Ili ndi mchere komanso alkali akutsutsana ndi alkali ndipo atha kukhalapo pang'ono mu PHUNZSI (3-11).

Kimacell®hec amasungunuka m'madzi ozizira, koma kufota kwa chilengedwe kumatha, ndipo kukhazikika kwa kutentha kwakukulu kapena malo amchere kwambiri ndi osauka. Kuphatikiza apo, hec siying'ono kwambiri ph ndipo imatha kugwiritsidwa ntchito mu prge ya 2-12.

Kukula

HPMC ili ndi mphamvu yolimba ndipo imakhala ndi chisungiko chamadzi.

Hec nawonso ali ndi mphamvu zambiri, koma mafano ake amakhudzidwa kwambiri ndi mtengo wometa ubweya ndikuwonetsa miseche.

Zochitika zapamwamba

HPMC ili ndi zochitika zina zapamwamba ndipo zimatha kupanga emulsization ndi mawonekedwe opanga mafilimu.

Hec ali ndi ntchito yotsika ndipo ilibe katundu wa emulsization, koma ali ndi katundu wabwino wopanga mafilimu.

3. Kusiyana

Gawo Lomanga

HPMC imagwiritsidwa ntchito kwambiri pazomangira, monga ufa wa matenya, matayala, matope, ndi zina zambiri.

Hec amagwiritsidwa ntchito kwambiri penti ya kumapetox ndi utoto wopangidwa ndi madzi ngati wotchinga ndi stebilizer kuti muwonjezere ma visction ndi zida za utoto wa utoto.

Phunziro la pharmaceutical

HPMC imagwiritsidwa ntchito ngati zokutira, olamulidwa omasulidwa ndi makapisole a mapiritsi mu gawo la pharmaceutical.

Hec sagwiritsidwa ntchito kwenikweni mu gawo la pharmaceutical ndipo nthawi zina monga tanthauzo la kuyimitsidwa kwa mankhwala.

Zodzikongoletsera ndi mankhwala a tsiku ndi tsiku

HPMC imagwiritsidwa ntchito pazinthu zosamalira khungu ndi zotupa kuti zipatse malonda bwino ndi kukhazikika kwa emulsifice.

Hec imagwiritsidwa ntchito kwambiri mu shampoo, kusamba gel, etc. kuti apereke zotsatira za kukula ndi kuyimitsidwa.

Gawo la chakudya

HPMC imagwiritsidwa ntchito ngati thickener, emulsifier ndi kusungunuka mu chakudya ndipo imagwiritsidwa ntchito kwambiri mu zakudya, masuzi ndi zinthu zophika.

Hec sagwiritsidwa ntchito kawirikawiri pazambirizo zakudya, koma zitha kugwiritsidwa ntchito ngati thickiner mu zakumwa zina ndi zodzikongoletsera.

4.. Mtengo ndi msika

HPMC nthawi zambiri imakhala yokwera mtengo kuposa hec chifukwa cha zovuta zake komanso kugwiritsa ntchito mitundu yonse. Njira yopanga hec imakhala yosavuta ndipo imagwiritsidwa ntchito pokulira komanso kukhazikika, chifukwa mtengo wake ndi wotsika.

Hydroxypylropyl (hpmc) ndi hydroxyethyl cellulose (Hec) aliyense ali ndi mawonekedwe awo apadera ndi katundu. Kimacell®hpmc ndioyenera kwambiri pazochitika zomwe zili ndi zofunikira kwambiri, zomwe zimakhala ndi madzi ndikupanga mafilimu, ndipo imakhala ndi ntchito zambiri. Msuzi, Komabe, nthawi zambiri imagwiritsidwa ntchito pofuula, mankhwala tsiku lililonse amagwiritsa ntchito kukula kwake ndikuyimitsidwa chifukwa cha mtengo wake wotsika komanso kukula kwake. Posankha zenizeni, kuganizira mokwanira kuyenera kupangidwa malinga ndi zofunikira zina ndi ndalama zachuma.
