Ethyl Cellulose- EC mutengesi

Ethyl cellulose imvura-insoluble polymer inotorwa kubva ku cellulose, yakasikwa biopolymer inowanikwa muchirimwa sero madziro. Inoshandiswa zvakanyanya mumaindasitiri akasiyana siyana, anosanganisira emishonga, chikafu, uye kutarisirwa kwemunhu, nekuda kweiyo yakasarudzika zvivakwa, zvinosanganisira solubility, firimu-kugadzira kugona, uye yakaderera chepfu. Ichi chinyorwa chichakurukura nezve zvivakwa, synthesis, uye mashandisirwo ethyl cellulose.

Properties of Ethyl Cellulose Ethyl cellulose chinhu chinonzi thermoplastic chinonyungudika muorganic solvents, senge ethanol, asi isinganyungudika mumvura. Iko kunyungudika kwe ethyl cellulose kunogona kugadziriswa nekushandura dhigirii yayo yekutsiva, iyo inoreva nhamba yemapoka ethyl paglucose unit mu cellulose molecule. Ethyl cellulose ine dhigirii repamusoro rekutsiva inonyungudika muorganic solvents, nepo ayo ane yakaderera dhigirii yekutsiva isinganyanyike.

Ethyl cellulose inozivikanwa nekugona kwayo kugadzira firimu uye inogona kushandiswa kugadzira yunifomu uye yakagadzikana firimu. Iyo firimu-inogadzira zvinhu zve ethyl cellulose inogona kuwedzeredzwa nekuwedzera plasticizers, senge dibutyl phthalate kana triacetin, iyo inowedzera kushanduka uye elasticity yefirimu. Ethyl cellulose mafirimu anowanzo shandiswa muindasitiri yemishonga semachira emapiritsi, macapsules, uye granules.

Synthesis yeEthyl Cellulose Ethyl cellulose inogadzirwa nekuita cellulose ne ethyl chloride pamberi pehwaro, senge sodium hydroxide kana potassium hydroxide. Kuita kunosanganisira kutsiviwa kwemapoka ehydroxyl mumorekuru we cellulose nemapoka ethyl, zvichikonzera kuumbwa kwe ethyl cellulose. Iyo dhigirii yekutsiva inogona kudzorwa nekugadzirisa maitiro ekuita, senge kusungirirwa kweanogadzirisa uye nguva yekuita.

Zvishandiso zveEthyl Cellulose Pharmaceuticals: Ethyl cellulose inoshandiswa zvakanyanya muindasitiri yemishonga nekuda kwekugona kwayo kugadzira firimu uye kuderera kwehuturu. Inoshandiswa sechinhu chekuputira mahwendefa, capsules, uye granules, iyo inovandudza kugadzikana kwavo uye inovadzivirira kubva pakuparara mudumbu redumbu. Ethyl cellulose coatings inogona zvakare kushandiswa kudzora kuburitswa kwezvinodhaka nekugadzirisa chiyero chavo chekunyungudika.

Chikafu: Ethyl cellulose inoshandiswa sekuwedzera kwechikafu kuvandudza magadzirirwo uye kugadzikana kwechikafu. Inowanzo shandiswa semukobvu, bhainda, uye kudzikamisa muzvokudya zvakagayiwa, zvakaita sesosi, madhirezi, uye zvinhu zvakabikwa. Ethyl cellulose inogona zvakare kushandiswa seyekupfekedza michero nemiriwo kuwedzera hupenyu hwavo hwesherufu uye kudzivirira kuparara.

Kuzvichengeta Pamunhu: Ethyl cellulose inoshandiswa muzvigadzirwa zvakasiyana-siyana zvekuchengeta munhu, zvakaita sezvizoro, mashamposi, uye mafuta ekuzora, nekuda kwekugona kwayo kugadzira firimu uye kusamira mvura. Inowanzo shandiswa seyakakora uye inodzikamisa muzvizoro uye inogona zvakare kushandiswa seyakagadzira firimu mumiriri mune zvekupfapfaidza bvudzi uye zvigadzirwa zvematayera.

Zvimwe Zvishandiso: Ethyl cellulose inoshandiswa mune zvimwe zvakasiyana-siyana zvinoshandiswa, senge ingi, marashi, zvinonamira, uye pendi. Inowanzo shandiswa sebhainda mumajasi uye semukobvu mumainki. Ethyl cellulose inogona zvakare kushandiswa sechinhu chinodzivirira mvura papepa uye sebhainda remakeramiki.

Muchidimbu, ethyl cellulose ipolymer isinganyungudika nemvura inotorwa kubva muselulosi iyo inoshandiswa zvakanyanya mumaindasitiri akasiyana siyana, kusanganisira emishonga, chikafu, uye kutarisirwa kwevanhu. Iyo inozivikanwa nekugona kwayo kugadzira firimu, yakaderera muchetura, uye inodzivirira mvura zvivakwa, zvichiita kuti ive yakakodzera kune akasiyana maapplication.
