Ndi mitundu ingati ya hydroxypropyl methylcellulose (HPMC) yomwe ilipo

Hydroxypropyl methylcellulose, yomwe imadziwika kuti HPMC, ndi polima yomwe imagwiritsidwa ntchito kwambiri pazakudya, zamankhwala, zomangamanga, zodzoladzola, komanso zinthu zosamalira anthu.Ndi chilengedwe cha cellulose ether chomwe chimapangidwa ndi kusintha kwa mankhwala a cellulose, polima yachilengedwe yochokera ku zomera.Kusinthaku kumaphatikizapo kuyambitsa magulu a hydroxypropyl ndi methyl ku molekyulu ya cellulose, yomwe imasintha mawonekedwe ake ndikupangitsa kuti ikhale yosunthika kuti igwiritsidwe ntchito pazinthu zosiyanasiyana.

Pali mitundu ingapo ya HPMC yomwe ikupezeka pamsika, iliyonse ili ndi zida zake zomwe zimapangitsa kuti ikhale yoyenera kugwiritsa ntchito zina.M'nkhaniyi, tikambirana mitundu ikuluikulu ya HPMC, makhalidwe awo ndi ntchito.

1. HPMC E5

HPMC E5 ndi mtundu wa HPMC amene ali otsika mamasukidwe akayendedwe ndi yodziwika ndi zomatira zake zabwino, posungira madzi ndi thickening katundu.Amagwiritsidwa ntchito kwambiri pamakampani omanga ngati chowonjezera pazopangira simenti kuti apititse patsogolo magwiridwe antchito, kusunga madzi, komanso mphamvu zomangirira.Amagwiritsidwanso ntchito popanga matailosi a ceramic, zinthu za gypsum, ndi zopaka pulasitala.M'makampani azakudya, amagwiritsidwa ntchito ngati kukhuthala muzakudya zamkaka, sosi, ndi supu.

2. HPMC E15

HPMC E15 ndi mtundu wa HPMC kuti ali kukhuthala sing'anga ndi yodziwika ndi mkulu posungira madzi, thickening ndi dispersing katundu.Amagwiritsidwa ntchito ngati thickening wothandizila ndi stabilizer pakupanga chakudya, komanso mu makampani mankhwala monga excipient kusintha mamasukidwe akayendedwe ndi kugwirizana kwa mankhwala.Amagwiritsidwanso ntchito popanga zodzoladzola ndi zinthu zosamalira anthu kuti aziwongolera komanso kukhazikika.

3. HPMC E50

HPMC E50 ndi mtundu wa HPMC amene ali mkulu mamasukidwe akayendedwe ndi yodziwika ndi thickening kwambiri, madzi posungira ndi filimu kupanga katundu.Amagwiritsidwa ntchito kwambiri popanga zokutira, utoto, ndi zomatira ngati zomatira komanso zomangira.Amagwiritsidwanso ntchito m'mafakitale azakudya kuti asinthe mawonekedwe ndi kukhazikika kwazinthu monga zowotcha, tchizi, ndi nyama yokonzedwa.

4. HPMC K4M

HPMC K4M ndi mtundu wa HPMC kuti ali ndi mamasukidwe akayendedwe mkulu ndi yodziwika ndi kwambiri thickening ndi zomatira katundu.Amagwiritsidwa ntchito kwambiri m'makampani opanga mankhwala monga chothandizira kukonza kuchuluka kwa kusungunuka ndi kupezeka kwa mankhwala, komanso kusintha momwe amatulutsira mankhwala.Amagwiritsidwanso ntchito m'makampani azakudya kuti azitha kukhazikika komanso kukhazikika kwazinthu monga zakumwa, zokhwasula-khwasula, ndi zotsekemera zoziziritsa kukhosi.

5. HPMC K100M

HPMC K100M ndi mtundu wa HPMC womwe uli ndi mamasukidwe apamwamba kwambiri ndipo umadziwika ndi kukhuthala kwake, kupanga mafilimu komanso kutulutsa kosalekeza.Amagwiritsidwa ntchito kwambiri m'makampani opanga mankhwala ngati chothandizira kukonza bioavailability ndikuwongolera kutulutsidwa kwamankhwala.Amagwiritsidwanso ntchito popanga zokutira, utoto, ndi zomatira kuti ziwongolere komanso zomangira.

Pomaliza, HPMC ndi polima yosunthika yomwe imakhala ndi ntchito zambiri m'mafakitale osiyanasiyana.Mitundu yosiyanasiyana ya HPMC yomwe ikupezeka pamsika imapangitsa kuti zitheke kusankha yoyenera kwambiri pakugwiritsa ntchito kwina kutengera katundu ndi mawonekedwe ake.Zotsatira zabwino za HPMC pamafakitale osiyanasiyana zapangitsa kuti ikhale chisankho chodziwika bwino ngati chowonjezera pazinthu zambiri.
