    Imithethonqubo nezindinganiso zinqunywa kanjani nge-hydroxyethyl acrylate?

    I-Hydroxyethyl Acrylate (KUHLE) Imithethonqubo kanye namazinga
    I-Hydroxyethyl Acrylate (HEA) ibhalwe njengezinto ezibolayo zeKlasi 8 kuKhathalogi yaseShayina yamaKhemikhali Ayingozi enenombolo ye-UN engu-2929. Umkhawulo wokuchayeka emsebenzini ubhekisela ezinhlinzekweni ze-GBZ 2.1-2019, kanti isilinganiso esivunyelwe sokuhlushwa (PC-TWA) esilinganiselwe isikhathi singama-5 mg/m³. Umthethonqubo we-EU REACH udinga amabhizinisi ukuthi athumele isimemezelo sedatha enobuthi salesi sidakamizwa futhi uvimbela ukusetshenziswa kwaso njengezinto zokuhlobisa. Izinga le-US OSHA libeka ukuthi amadivayisi okugeza aphuthumayo kumele afakwe endaweni yokusebenza, futhi ibanga ukusuka endaweni yokusebenza akufanele lidlule ukuhamba ngezinyawo kwemizuzwana eyi-10. I-Hydroxyethyl Acrylate (HEA).

    Isakhiwo se-hydroxyethyl acrylate HEA sinquma ukuthi ine-polarity ethile. Ngenxa yomehluko ku-electronegativity yama-athomu ahlukene ku-molecule, ukusatshalaliswa kweshaja akulingani. Lokhu polarity kuyivumela ukuthi ixubane kahle nezinye izinyibilikisi ze-polar, njenge i-ethanol namanzi.
