(Hydroxypropyl)methyl cellulose | CAS 9004-65-3

(Hydroxypropyl)methyl cellulose, yomwe imadziwikanso ndi chidule chake HPMC kapena nambala yake ya CAS 9004-65-3, ndi cellulose ether yochokera ku cellulose yachilengedwe. Ndi polymer ya semi-synthetic yomwe imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa cha mawonekedwe ake apadera komanso kusinthasintha. Tawonani mozama pagululi:

Kapangidwe ndi Katundu:
1 Kapangidwe: HPMC imapangidwa kudzera mu kusintha kwa mankhwala a cellulose, pomwe magulu onse a methyl (-CH3) ndi hydroxypropyl (-CH2CHOHCH3) amalowetsedwa pamsana wa cellulose.
2 Degree of Substitution (DS): Mlingo wolowa m'malo umanena za kuchuluka kwa magulu olowa m'malo pagawo la shuga mu tcheni cha cellulose. Imasankha katundu wa HPMC, monga solubility, viscosity, ndi luso lopanga mafilimu.
3 Katundu: HPMC imawonetsa zinthu monga kukhuthala, kusunga madzi, kupanga mafilimu, ndi zochitika zapamtunda. The katundu akhoza kusinthidwa ndi kulamulira DS pa kaphatikizidwe.

Kupanga:
1.Kupeza Ma Cellulose: Ma cellulose, zopangira zoyambira za HPMC, zimatengedwa kuchokera kumalo ongowonjezedwanso monga zamkati kapena thonje.
Etherification: Cellulose imalowa etherification, pomwe imayendetsedwa ndi propylene oxide kuyambitsa magulu a hydroxypropyl kenako ndi methyl chloride kuwonjezera magulu a methyl.
2.Kuyeretsa: Ma cellulose osinthidwa amatsukidwa kuti achotse zonyansa ndi zotsalira, zomwe zimapangitsa kuti HPMC ikhale yomaliza.
Mapulogalamu:
3.Construction Industry: HPMC imagwiritsidwa ntchito kwambiri muzomangamanga monga matope opangidwa ndi simenti, pulasitala, ndi zomatira za matailosi kuti zitheke kugwira ntchito, kusunga madzi, ndi kumamatira.
4.Pharmaceuticals: Zimagwira ntchito ngati binder, thickener, film kale, ndi stabilizer mu mankhwala opangira mankhwala kuphatikizapo mapiritsi, makapisozi, ophthalmic solutions, ndi topical creams.
5.Food Industry: HPMC imagwira ntchito ngati thickener, stabilizer, ndi emulsifier mu zakudya zosiyanasiyana monga sauces, mavalidwe, ayisikilimu, ndi kuphika katundu.
6.Zodzoladzola ndi Zosamalira Munthu: Muzodzoladzola ndi zinthu zosamalira munthu, HPMC imagwiritsidwa ntchito ngati thickener, suspending agent, film kale, ndi moisturizer mu zopaka, lotions, shampoos, ndi gels.
7.Paints and Coatings: Imawonjezera kukhuthala, kukana kwa sag, komanso kupanga mafilimu a utoto wamadzi, zomatira, ndi zokutira.
Pomaliza:
(Hydroxypropyl) methyl cellulose, yokhala ndi mitundu yosiyanasiyana ya ntchito ndi zinthu zabwino, ndiyofunikira kwambiri pazinthu zambiri zamafakitale ndi zamalonda. Udindo wake pakupititsa patsogolo magwiridwe antchito, kukhazikika, ndi magwiridwe antchito amitundu yosiyanasiyana kumapangitsa kuti ikhale yofunika kwambiri m'magawo angapo. Pamene mafakitale akupitilira kupanga zatsopano, kufunikira kwa HPMC kukuyembekezeka kupitilirabe, ndikupititsa patsogolo njira zopangira ndikugwiritsa ntchito.
