Ethyl cellulose solubility muacetone

Ethyl cellulose ipolymer inoshandiswa zvakanyanya mumaindasitiri akasiyana siyana, kusanganisira mishonga, chikafu, uye kutarisira wega. Iyo inozivikanwa nekunaka kwayo yekugadzira firimu zvinhu, kuenderana kwakanyanya nezvimwe zvinhu, uye kuramba kwakanaka kumakemikari uye zvakatipoteredza. Chimwe chezvinhu zvakakosha zve ethyl cellulose kunyungudika kwayo, iyo inogona kusiyana zvichienderana neyakagadziriswa inoshandiswa.

Acetone inogadziriswa yakajairika inowanzoshandiswa mukugadzira ethyl cellulose mafirimu uye machira. Ethyl cellulose inonyungudika zvishoma muacetone, zvichireva kuti inogona kunyungudika kune imwe nhanho asi inogona kusanyungudika zvizere. Iyo dhigirii yekunyungudika kwe ethyl cellulose muacetone inotsamira pazvinhu zvakasiyana senge huremu hwemamorekuru, dhigirii re ethoxylation, uye kusungirirwa kwepolymer.

Kazhinji, yakakwira molecular uremu ethyl cellulose inoita kunge isinganyanyike muacetone kana ichienzaniswa neakadzika mamorekuru uremu ethyl cellulose. Izvi zvinodaro nekuti epamusoro mamorekuru huremu mapolymers ane dhigirii repamusoro repolymerization, zvichikonzera imwe yakaoma uye yakasimba yakarongedzerwa chimiro chinopokana nekugadzirisa. Saizvozvo, ethyl cellulose ine dhigirii repamusoro re ethoxylation inoita kunge isinganyanyike muacetone nekuda kwekuwedzera hydrophobicity yepolymer.

Iko kunyungudika kwe ethyl cellulose muacetone kunogonawo kukanganiswa nekusangana kwepolymer mune solvent. Pakudzika kwakadzika, ethyl cellulose inonyanya kunyungudika muacetone, nepo pakakwirira, solubility inogona kuderera. Izvi zvinokonzerwa nekuti pakukwirira kwakanyanya, iyo ethyl cellulose mamorekuru anowanzo kudyidzana, achigadzira network yemaketani epolymer isinganyanyi kunyungudika musolvent.

Iyo solubility ye ethyl cellulose muacetone inogona kukwidziridzwa nekuwedzerwa kwezvimwe zvinonyungudutsa kana plasticizers. Semuenzaniso, kuwedzerwa kwe ethanol kana isopropanol kune acetone kunogona kuwedzera kunyungudika kwe ethyl cellulose nekuvhiringidza kupindirana kwe intermolecular pakati pemaketani epolymer. Saizvozvo, kuwedzera kweplasticizers senge triethyl citrate kana dibutyl phthalate kunogona kuwedzera kunyungudika kwe ethyl cellulose nekudzikisa ma intermolecular masimba pakati pe polymer cheni.

Muchidimbu, ethyl cellulose inonyungudika zvishoma muacetone, uye kunyungudika kwayo kunogona kusiyana zvichienderana nezvinhu zvakasiyana senge huremu hwemamorekuru, dhigirii re ethoxylation, uye kusungirirwa kwepolymer. Iko kunyungudika kwe ethyl cellulose muacetone inogona kukwidziridzwa nekuwedzera kwezvimwe zvinonyungudutsa kana mapurasitiki, zvichiita kuti ive inosiyana-siyana polymer yekushandisa mukushandisa kwakasiyana.
