Iwe unogadzira sei ethyl cellulose?

Ethyl cellulose i polymer yakagadzirwa kubva ku cellulose, organic compound inowanikwa mumiti. Ihwo hupfu huchena, husinganhuhwi, husina kunaka husinganyungudike mumvura uye nezvinonyungudutsa zvakanyanyisa. Ethyl cellulose EC inoshandiswa mumhando dzakasiyana dzekushandisa, kusanganisira machira, zvinonamira, uye mishonga.

Maitiro ekugadzira ethyl cellulose anosanganisira akati wandei matanho. Danho rekutanga nderekutora cellulose, iyo inogona kuwanikwa kubva kune zvinomera zvakaita sedonje, huni, kana bamboo. Iyo cellulose inozobatwa neasidhi yakasimba, senge sulfuric acid, kuputsa cellulose muchikamu chayo cheshuga mamorekuru. Mamorekuru eshuga anobva aitwa ne ethyl doro kugadzira ethyl cellulose.

Iyo ethyl cellulose inobva yacheneswa nemaitiro anonzi fractional precipitation. Izvi zvinosanganisira kuwedzera solvent kumushonga we ethyl cellulose, izvo zvinoita kuti ethyl cellulose ibude mumushonga. Iyo precipitated ethyl cellulose inobva yaunganidzwa uye yakaomeswa.

Nhanho yekupedzisira mukuita ndeyekushandura yakaomeswa ethyl cellulose kuita hupfu. Izvi zvinoitwa nekukuya ethyl cellulose kuita hupfu hwakatsetseka. Iyo poda inobva yagadzirira kushandiswa mune zvakasiyana-siyana zvekushandisa.

Ethyl cellulose chinhu chakasiyana-siyana chinogona kushandiswa mumhando dzakasiyana dzekushandisa. Inoshandiswa mumachira, zvinonamira, uye mishonga, uye inogona kushandiswa kugadzira mafirimu, mafiinzi, uye gels. Inoshandiswawo mukugadzira pendi, ingi, nezvimwe zvinhu. Ethyl cellulose inoshandiswawo seyakakora mumiriri mune zvigadzirwa zvekudya, uye seyakagadzika muzvizoro.
