HPMC polima

HPMC (Hydroxypropyl Methylcellulose) ndi polima yopanda ionic, yosungunuka m'madzi yochokera ku cellulose.Amagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana, kuphatikizapo mankhwala, zakudya, zodzoladzola, ndi mafakitale ena.HPMC ndi zosunthika polima kuti angagwiritsidwe ntchito kusintha katundu thupi kachitidwe amadzimadzi, monga mamasukidwe akayendedwe, kukangana padziko, ndi adhesion.

HPMC ndi polysaccharide yopangidwa ndi mayunitsi obwerezabwereza a mamolekyu a shuga, omwe amalumikizidwa pamodzi ndi magulu a ether ndi methyl.Magulu a ether amapatsa HPMC kusungunuka kwamadzi, pomwe magulu a methyl amapereka polima mawonekedwe ake osakhala a ionic.Izi zimapangitsa HPMC kukhala yabwino kusankha ntchito zosiyanasiyana, chifukwa akhoza omwazika mosavuta m'madzi ndi zina zosungunulira polar.

HPMC ntchito zosiyanasiyana mafakitale, kuphatikizapo mankhwala, chakudya, zodzoladzola, ndi mafakitale ena.M'makampani opanga mankhwala, HPMC imagwiritsidwa ntchito ngati binder, disintegrant, komanso kupanga mafilimu.Amagwiritsidwanso ntchito ngati excipient mu mapiritsi ndi makapisozi, monga kumathandiza kusintha flowability ndi compressibility wa ufa.M'makampani azakudya, HPMC imagwiritsidwa ntchito ngati thickener, stabilizer, ndi emulsifier.Amagwiritsidwanso ntchito m'makampani opanga zodzoladzola monga wopangira mafilimu komanso emulsifier.

HPMC ndi polima otetezeka komanso ogwira ntchito kuti si poizoni ndi osakwiyitsa.Komanso ndi biodegradable komanso zachilengedwe.HPMC imapezeka m'makalasi ndi mitundu yosiyanasiyana, monga ufa, ma granules, ndi flakes.Imapezekanso mu masikelo osiyanasiyana a mamolekyu, omwe angapangidwe kuti akwaniritse zofunikira zenizeni.

HPMC ndi chisankho chabwino kwa osiyanasiyana ntchito chifukwa cha zinthu zosiyanasiyana, chitetezo, ndi mogwira mtima.Ndi polima yotsika mtengo komanso yodalirika yomwe ingagwiritsidwe ntchito kusintha mawonekedwe amadzi am'madzi.HPMC ndizofunikira kwambiri pazogulitsa zambiri, ndipo kugwiritsidwa ntchito kwake kukuyenera kupitiliza kukula m'tsogolomu.
