Kodi wopanga hypromellose ndi ndani?

Kima Chemical imapereka mankhwala osiyanasiyana a hypromellose kuti akwaniritse zosowa za ntchito zosiyanasiyana. Zogulitsa zamakampani za hypromellose zimapezeka m'makalasi osiyanasiyana a viscosity ndi ma degree of substitution (DS), komanso mawonekedwe osinthidwa kuti akwaniritse zofunikira zamakasitomala.

Zogulitsa za Kima Chemical za hypromellose zimapangidwa pogwiritsa ntchito ukadaulo wapamwamba wopanga komanso njira zowongolera zowongolera kuti zitsimikizire kukhazikika komanso magwiridwe antchito. Zogulitsa zamakampani za hypromellose zimagwirizananso ndi miyezo yapadziko lonse lapansi, kuphatikiza USP, EP, JP, ndi FCC.

Hypromellose ndi polymer yosunthika yomwe imagwiritsidwa ntchito m'mafakitale osiyanasiyana. Kima Chemical ndi omwe amapanga hypromellose, omwe amapereka magiredi osiyanasiyana ndi mafotokozedwe kuti akwaniritse zosowa zamapulogalamu osiyanasiyana. Zogulitsa za Kima Chemical za hypromellose zimapangidwa pogwiritsa ntchito ukadaulo wapamwamba wopanga komanso njira zowongolera zowongolera kuti zitsimikizire kukhazikika komanso magwiridwe antchito. Ndi katundu wake wabwino kwambiri komanso magwiridwe antchito osiyanasiyana, hypromellose ndi chinthu chofunikira kwambiri pazogulitsa ndi mafakitale ambiri.

Hypromellose, yomwe imadziwikanso kuti hydroxypropyl methylcellulose (HPMC), ndi polima yopangidwa ndi semi-synthetic yomwe imagwiritsidwa ntchito m'mafakitale osiyanasiyana. Amapangidwa ndi cellulose yosintha mankhwala, polima yachilengedwe yomwe imapezeka muzomera. Hypromellose imagwiritsidwa ntchito ngati thickener, emulsifier, and stabilizer muzakudya, komanso ngati binder, film-former, and lubricant in the pharmaceutical industry. Kima Chemical ndi omwe amapanga hypromellose, omwe amapereka magiredi osiyanasiyana ndi mafotokozedwe kuti akwaniritse zosowa zamapulogalamu osiyanasiyana.

Kapangidwe ka Mankhwala a Hypromellose

Hypromellosendi polima yosungunuka m'madzi yomwe imachokera ku cellulose. Amapangidwa pochita ma cellulose ndi propylene oxide ndi methyl chloride. Polima wotulukayo amakhala ndi kulemera kwa ma cell a 10,000 mpaka 1,000,000 Daltons, kutengera kuchuluka kwa m'malo (DS) ndi kalasi ya viscosity.

Kapangidwe kakemidwe ka hypromellose kumakhala ndi msana wa cellulose wokhala ndi magulu a hydroxypropyl ndi methyl omwe amalumikizidwa ndi mayunitsi a anhydroglucose. Digiri ya m'malo (DS) imatanthawuza kuchuluka kwa magulu a hydroxypropyl ndi methyl pa unit anhydroglucose. DS imatha kuyambira 0.1 mpaka 2.5, kutengera zomwe mukufuna hypromellose.

Makhalidwe a Hypromellose

Hypromellose ndi ufa woyera womwe umakhala wopanda fungo komanso wosakoma. Amasungunuka m'madzi ndi zosungunulira zambiri za organic, koma samasungunuka mu zosungunulira zambiri za nonpolar. Hypromellose imakhala ndi mamasukidwe apamwamba pazambiri zotsika, zomwe zimapangitsa kuti ikhale yolimba komanso yomangira. Imakhalanso ndi zinthu zabwino kwambiri zopangira mafilimu, zomwe zimapangitsa kuti zikhale zothandiza popanga zokutira ndi mafilimu.

Makhalidwe a hypromellose amadalira kuchuluka kwa m'malo (DS) ndi kalasi ya viscosity. Magulu apamwamba a DS amakhala ndi kusungunuka kwamadzi kwambiri komanso kutentha kocheperako, pomwe magawo otsika a DS amakhala ndi kutentha kwambiri komanso kukhazikika kwamafuta. Gulu la viscosity limatsimikizira makulidwe a yankho la hypromellose komanso kuthekera kwake kupanga ma gels.

Kugwiritsa ntchito Hypromellose

Hypromellose imagwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikizapo chakudya, mankhwala, zodzoladzola, ndi zomangamanga. M’makampani a zakudya, hypromellose amagwiritsidwa ntchito ngati thickener, emulsifier, and stabilizer muzinthu zosiyanasiyana, kuphatikizapo ayisikilimu, sauces, ndi zinthu zophika. M'makampani opanga mankhwala, hypromellose amagwiritsidwa ntchito ngati binder, filimu-kale, ndi mafuta m'mapiritsi, makapisozi, ndi mafuta odzola. Amagwiritsidwanso ntchito ngati ❖ kuyanika m'mawu owongolera omasulidwa.

M'makampani opanga zodzoladzola, hypromellose amagwiritsidwa ntchito ngati thickener, emulsifier, ndi filimu-former mu lotions, creams, ndi zodzoladzola mankhwala. M'makampani omanga, hypromellose amagwiritsidwa ntchito ngati chowonjezera komanso chomangira zinthu zopangidwa ndi simenti, monga matope ndi ma grouts.
