Ethyl cellulose hydrophilic kana hydrophobic

Ethyl cellulose i polymer yekugadzira iyo inoshandiswa zvakanyanya mumaindasitiri akasiyana siyana, kusanganisira mishonga, chikafu, uye kutarisira wega. Iyo inozivikanwa nekunaka kwayo kwekugadzira firimu, kuenderana kwakanyanya nezvimwe zvinhu, uye kuramba kwakanaka kumakemikari uye zvakatipoteredza zvinhu. Chimwe chezvinhu zvakakosha zve ethyl cellulose ndeye hydrophobicity, inova chiyero chekubatana kwayo nemvura.

Hydrophobicity ipfuma yechinhu chinotsanangura maitiro ayo ekudzinga mamorekuru emvura. Kazhinji, zvinhu zve hydrophobic hazvinyunguriki kana kusanyungudika mumvura uye zvinowanzo shamwaridzana nemamwe mamorekuru ehydrophobic. Hydrophobicity inowanzo onekwa nekuvapo kwemapoka asiripolar kana akaderera-polar muchimiro chemolecular, senge hydrocarbon cheni kana zvindori zvinonhuhwirira.

Ethyl cellulose inoonekwa se hydrophobic polymer nekuda kwekuvapo kwemapoka ethyl mune yayo molecular chimiro. Iwo ethyl mapoka haana polar uye hydrophobic, uye kuvapo kwavo kunowedzera iyo yakazara hydrophobicity yepolymer. Uye zvakare, ethyl cellulose ine yakaderera dhigirii yekutsiva ethyl mapoka, ayo anowedzera kubatsira kune ayo hydrophobic hunhu.

Nekudaro, iyo hydrophobicity ye ethyl cellulose inogona kugadziridzwa nekuchinja dhigirii rekutsiva kana nekuwedzera hydrophilic mapoka kune iyo polymer chimiro. Semuenzaniso, kuiswa kwemapoka e-hydrophilic akadai se hydroxyl kana mapoka e-carboxyl anogona kuwedzera hydrophilicity yepolymer uye kuvandudza kunyungudika kwayo mumvura. Iyo dhigirii yekutsiva inogona zvakare kuwedzerwa kuwedzera huwandu hwemapoka ehydrophilic uye kuwedzera hydrophilicity yepolymer.

Kunyangwe iyo hydrophobicity, ethyl cellulose ichiri kutorwa sechinhu chinobatsira kune akasiyana maapplication, kunyanya muindasitiri yemishonga. Hunhu hwayo hwe hydrophobic hunoita kuti ive yakanakisa chipingamupinyi zvinhu zvekutakura zvinodhaka masisitimu, sezvo ichikwanisa kudzivirira kupinda kwehunyoro kana zvimwe zvinhu zve hydrophilic mufomu yedosi. Izvi zvinogona kubatsira kuchengetedza kugadzikana uye kushanda kwemushonga kwenguva yakareba.

Muchidimbu, ethyl cellulose ndeye hydrophobic polymer nekuda kwekuvapo kweasiripolar ethyl mapoka mune yayo molecular chimiro. Nekudaro, iyo hydrophobicity inogona kugadziridzwa nekushandura dhigirii rekutsiva kana kuwedzera hydrophilic mapoka kune iyo polymer chimiro. Kunyangwe iyo hydrophobic hunhu, ethyl cellulose ichiri chinhu chinobatsira kune akasiyana maapplication, kunyanya muindasitiri yemishonga.
