Cellulose ether

Cellulose ethers iboka remakemikari akagadziridzwa cellulose derivatives, apo mapoka ehydroxyl (-OH) emamorekuru e cellulose anotsiviwa nemapoka ether (-OR). Aya magadzirirwo anosimudzira zvimiro zve cellulose, zvichiita kuti zvive zvakakosha mumaindasitiri akasiyana.

Cellulose Ether yakaratidza kuti inobatsira zvikuru mapolymers echisikigo, kutsvaga kushandiswa munzvimbo dzinosanganisira zvokudya, zvigadzirwa zvekuchengeta munhu, makemikari emunda wemafuta, kuvaka, mapepa, adhesives, uye machira.;

Vane kukosha kwakanyanya mukushandiswa kwemishonga nekuda kwehunhu hunosanganisira yakakwirira girazi tembiricha, yakakwira makemikari uye photochemical kugadzikana, solubility, shoma crystallinity, hydrogen bonding kugona, uye yakaderera toxicity.;

Nezve muchetura, cellulose ethers haatombokwanisi kupinda mukati memudumbu maentestinal enterocytes uye mazhinji atove mukugadzirwa kwakabvumidzwa neUS Food and Drug Administration.

Cellulose ethers mapolymer anonyungudika nemvura anogadzirwa nekemikari shanduko ye cellulose.;

Iwo makuru ekutengesa cellulose ethers anosanganisira carboxymethylcellulose (CMC), methylcellulose (MC) uye anobva kunze senge hydroxypropyl methylcellulose (HPMC) uye hydroxyethyl methylcellulose (HEMC), hydroxyethylcellulose (HEC) uye zvinobva kune zvakaita se ethyl hydroxyethylHEcellulose (methylEthylethylHEcellulose) ), hydroxypropyl cellulose (HPC), uye ethylcellulose (EC).

Cellulose ethersshanda sezvinodzikamisa, makobvu, uye viscosity modifiers mumaindasitiri mazhinji, anosanganisira chikafu, mishonga, zvigadzirwa zvekuchengeta munhu, makemikari emunda wemafuta, kuvaka, mapepa, zvinonamira, uye machira.;

Mukusarudza maapplication, vanokwikwidzana uye nemapolymer ekugadzira anonyungudika nemvura (polyvinyl doro, polyurethane associative thickeners, polyacrylates) nemapolymers anonyungudika nemvura (xanthan gum, carrageenan, mhashu bhinzi chingamu).

Sarudzo yepolymer inotarwa nemutengo/kuita kutengeserana-offs, kuwanikwa, uye kureruka kwekugadzirisa chigadzirwa kunoenderana nemutengo / maitiro ekufunga.

Cellulose ether ndiyo powdered cellulose ether inogadzirwa nehuni faibha kana yakanatswa pfupi donje faibha sechinhu chikuru mbishi, mushure mekurapa kwemakemikari uye nekuita kwe etherifying agents senge chlorinated ethylene, chlorinated propylene uye oxidized ethylene.

Nzira yekugadzira cellulose ether yakaoma.;
