Kusiyana pakati pa hydroxypropyl wowuma ndi hydroxypropyl methyl cellulose

Hydroxypropyl wowuma ndi hydroxypypyl methy cellose (hpmc) onse osinthidwa omwe amagwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikizapo chakudya, mankhwala odzola, odzola, ndi zodzola. Akamalowereranso, amakhala ndi kusiyana kwina pankhani ya kapangidwe kake, katundu, ndi mapulogalamu. Nawa kusiyana kwakukulu pakati pa hydroxypropyl wowuma ndi hpmc:

Kapangidwe ka mankhwala:

1. Hydroxypropyl wowuma:
   • Hydroxypropyl wowuma ndi wowuma wosinthidwa ndikuyambitsa magulu a hydroxypyl mu molekyulu ya wowuma.
   • Wowuma ndi polysardide wopangidwa ndi zigawo za shuga limodzi ndi ma glycosidic. Hydroxypylation imakhudzana ndi ma hydroxyl (-oh) magulu owuma molekyulu ndi hydroxypropyl (-ch2chohch3) magulu.
2. Hydroxypypyl methyl cellulose (hpmc):
   • HPMC ndi cellulose yosinthidwa ether ether yopezeka ndi ma hydroxypyl ndi methyl magulu a cellulose molekyulu.
   • Cellulose ndi polysaccharide yopangidwa ndi zigawo za shuga wolumikizidwa pamodzi ndi β (1 → 4) zomangira. Hydroxypropropropylaty imayambitsa hydroxypyl (-ch2chohch3) magulu, pomwe methylation imayambitsa methyl (-ch3) magulu am'madzi am'deralo.

Katundu:

1. Kusungunuka:
   • Hydroxypyl wowuma nthawi zambiri amasungunuka m'madzi otentha koma amatha kuwonetsa kusungunuka pang'ono m'madzi ozizira.
   • HPMC imasungunuka m'madzi onse ozizira komanso otentha, ndikupanga zomveka, zothetsera ma viscous. Kusungunuka kwa HPMC kumadalira kuchuluka kwa zolowa m'malo mwazolowa (DS) ndi kulemera kwa polymer.
2. Makulidwe:
   • Hydroxypropyl smarch amatha kuwonetsa katundu wa ma viscencet, koma ma visccy nthawi zambiri amakhala otsika poyerekeza ndi HPMC.
   • HPMC imadziwika chifukwa cha kuchuluka kwake kwakukulu komanso kusinthika. Makulidwe a ma hpmc mayankho a HPMC akhoza kusinthidwa ndikusinthanitsa ndende, DS, ndi kulemera kwamwano.

Mapulogalamu:

1. Chakudya ndi mankhwala:
   • Hydroxypropyl wowuma nthawi zambiri amagwiritsidwa ntchito ngati thicker, okhazikika, ndi zopangira mankhwala muzakudya monga zakudya, soseji, ndi zakudya. Itha kugwiritsidwanso ntchito pamapangidwe opangira mankhwala.
   • HPMC imagwiritsidwa ntchito kwambiri mu chakudya, mankhwala opangira mankhwala, komanso zodzoladzola ngati thiccener, elsilsifier, kusungunuka, kanema wakale, komanso wowamasulira. Nthawi zambiri amapezeka muzopanga monga mapiritsi, mafuta, mafuta, ndi zinthu zaumwini.
2. Ntchito Zomanga ndi Zomanga:
   • HPMC imagwiritsidwa ntchito kwambiri m'makampani omanga monga kuwonjezera pazinthu zomata za sile monga tiles, mavolo, otembenukira, ndi mazira. Imapereka kusungidwa kwamadzi, kugwirira ntchito, kutsatira, komanso kukonza kusintha mu ntchito izi.

Pomaliza:

Pomwe onse hydroxpyl wowuma ndi hpmc amasinthidwa polysacchacides okhala ndi zofananira zofananira, amakhala ndi zida zopangidwa ndi mankhwala, ndi ntchito. Hydroxypropyl wowuma makamaka amagwiritsidwa ntchito mu chakudya ndi mankhwala opangira mankhwala, pomwe HPMC imagwiritsa ntchito kwambiri chakudya, mankhwala opangira mankhwala, zodzola zodzola. Chisankho pakati pa hydroxypropyl wowuma ndi hpmc zimatengera zofunikira mwatsatanetsatane zomwe mukufuna.
