Kodi HPMC ndi biopolymer?

Hydroxypropylmethylcellulose (HPMC) ndikusintha kopangidwa kwa cellulose, polima wachilengedwe wopezeka m'makoma a cellulose. Ngakhale HPMC payokha si biopolymer kwenikweni chifukwa imapangidwa ndi mankhwala, nthawi zambiri imatengedwa ngati semi-Synthetic kapena modified biopolymers.

A. Chiyambi cha hydroxypropyl methylcellulose:

Hydroxypropyl methylcellulose (HPMC):

Hydroxypropylmethylcellulose (HPMC) ndi chochokera ku cellulose, polima liniya wopangidwa ndi mayunitsi a shuga. Cellulose ndiye gawo lalikulu la makoma a cell cell. HPMC imapangidwa ndi kusintha kwa cellulose powonjezera magulu a hydroxypropyl ndi methyl.

B. Kapangidwe ndi kachitidwe:

1.Mapangidwe a Chemical:

Kapangidwe kakemidwe ka HPMC kumakhala ndi ma cellulose backbone unit okhala ndi hydroxypropyl ndi magulu a methyl. Degree of substitution (DS) imatanthawuza kuchuluka kwa magulu a hydroxypropyl ndi methyl pagawo la shuga mu tcheni cha cellulose. Kusintha kumeneku kumasintha mawonekedwe a thupi ndi mankhwala a cellulose, zomwe zimapangitsa kuti pakhale magiredi angapo a HPMC okhala ndi ma viscosity osiyanasiyana, kusungunuka ndi katundu wa gel.

2.Zakuthupi:

Kusungunuka: HPMC imasungunuka m'madzi ndikupanga mayankho omveka bwino, ndikupangitsa kuti ikhale yofunika kwambiri pazogwiritsa ntchito zosiyanasiyana kuphatikiza mankhwala, chakudya, ndi zomangamanga.

Viscosity: The mamasukidwe akayendedwe a HPMC yankho akhoza lizilamuliridwa ndi kusintha mlingo wa m'malo ndi molecular kulemera kwa polima. Katunduyu ndi wofunikira pakugwiritsa ntchito monga mankhwala opangira mankhwala ndi zomangira.

3. Ntchito:

Thickeners: HPMC amagwiritsidwa ntchito ngati thickener mu zakudya, mankhwala, ndi mankhwala chisamaliro munthu.

Kupanga Mafilimu: Ikhoza kupanga mafilimu ndipo ingagwiritsidwe ntchito kupaka mapiritsi ndi makapisozi amankhwala, komanso kupanga mafilimu ogwiritsira ntchito zosiyanasiyana.

Kusungirako Madzi: HPMC imadziwika chifukwa cha kusunga madzi, kuthandiza kukonza magwiridwe antchito komanso kuthirira kwazinthu zomangira monga zopangira simenti.

C. Kugwiritsa ntchito HPMC:

1. Mankhwala osokoneza bongo:

Kupaka Papiritsi: HPMC imagwiritsidwa ntchito popanga zokutira mapiritsi kuti azitha kutulutsa mankhwala ndikuwongolera bata.

Kupereka mankhwala pakamwa: The biocompatibility and controlled release properties of HPMC imapangitsa kukhala koyenera kwa machitidwe operekera mankhwala pakamwa.

2. Makampani omanga:

Zogulitsa Zamatope ndi Simenti: HPMC imagwiritsidwa ntchito pomanga kuti ipititse patsogolo kusunga madzi, kugwira ntchito komanso kumamatira.

3. Makampani azakudya:

Thickeners ndi Stabilizers: HPMC amagwiritsidwa ntchito ngati thickener ndi stabilizer mu zakudya kusintha maonekedwe ndi bata.

4. Zothandizira pawekha:

Kupanga Zodzikongoletsera: HPMC imaphatikizidwa muzodzoladzola zodzikongoletsera chifukwa cha mawonekedwe ake opanga mafilimu ndi kukhuthala.

5. Paints ndi zokutira:

Zopaka zam'madzi: M'makampani opanga zokutira, HPMC imagwiritsidwa ntchito popanga madzi kuti apititse patsogolo rheology ndikuletsa kukhazikika kwa pigment.

6. Zoganizira zachilengedwe:

Ngakhale HPMC payokha si polymer yotha kuwonongeka kwathunthu, chiyambi chake cha cellulosic chimapangitsa kuti ikhale yogwirizana ndi chilengedwe poyerekeza ndi ma polima opangidwa kwathunthu. HPMC imatha kuwononga zinthu m'mikhalidwe ina, ndipo kugwiritsidwa ntchito kwake m'mapangidwe okhazikika komanso osawonongeka ndi gawo la kafukufuku wopitilira.

Hydroxypropylmethylcellulose (HPMC) ndi polymer ya semi-synthetic yochokera ku cellulose. Zake zapadera zimapangitsa kuti zikhale zofunikira m'mafakitale osiyanasiyana kuphatikizapo mankhwala, zomangamanga, chakudya, chisamaliro chaumwini ndi utoto. Ngakhale si mtundu weniweni wa biopolymer, chiyambi chake cha cellulose ndi kuthekera kwa biodegradation zikugwirizana ndi kufunikira kokulirapo kwa zida zokhazikika pamagwiritsidwe osiyanasiyana. Kafukufuku wopitilira akupitilizabe kufufuza njira zolimbikitsira kuyanjana kwa chilengedwe kwa HPMC ndikukulitsa kugwiritsidwa ntchito kwake pamapangidwe ogwirizana ndi chilengedwe.
