Cov txiaj ntsig ntawm cellulose ethers rau tshuaj txheej

Hauv kev lag luam kws tshuaj, hydroxypropyl carboxymethyl cellulose (HPMC) tuaj yeem siv los ua cov tshuaj excipient thiab siv dav hauv cov tshuaj hauv qhov ncauj matrix tswj kev tso tawm thiab kev npaj tso tawm. Nws yog siv los ua cov khoom tso tawm retardant los tswj kev tso tawm cov tshuaj thiab ua cov khoom siv txheej txheem tso tawm tus neeg sawv cev, kev tso tawm pellets, thiab cov tshuaj tiv thaiv tso tawm. Feem ntau siv yog methyl carboxymethyl cellulose thiab ethyl carboxymethyl cellulose. Piv txwv li, MC feem ntau yog siv los ua cov ntsiav tshuaj thiab cov tshuaj ntsiav, los yog cov ntsiav tshuaj uas muaj suab thaj. Cov cellulose ethers zoo tuaj yeem siv rau hauv kev lag luam khoom noj thiab yog cov thickeners zoo, stabilizers, excipients, dej retainers, thiab mechanical foaming agents hauv ntau yam khoom noj. Methyl cellulose thiab hydroxypropyl methyl cellulose tau lees paub tias yog cov tshuaj metabolically inert uas tsis muaj mob rau lub cev. High-purity (purity saum 99.5%) carboxymethyl cellulose (CMC) tuaj yeem muab ntxiv rau cov khoom noj xws li mis nyuj thiab qab zib, khoom qab zib, jams, jellies, zaub mov kaus poom, rooj syrups, thiab dej haus. Carboxymethyl cellulose nrog purity ntau dua 90% tuaj yeem siv rau hauv cov khoom noj, xws li hauv kev thauj mus los thiab khaws cov txiv hmab txiv ntoo tshiab. Cov hnab yas zoo li no muaj qhov zoo ntawm kev khaws cia zoo, muaj kuab paug tsawg, tsis muaj kev puas tsuaj, thiab kev siv tshuab yooj yim.
