Imigaqo nemigangatho imiselwe njani i-hydroxyethyl acrylate?

I-Hydroxyethyl Acrylate (KULUNGILE) Imigaqo neMigangatho
I-Hydroxyethyl Acrylate (HEA) idweliswe njengezinto ezirhabaxa zeKlasi yesi-8 kwiKhathalogu yeeKhemikhali eziyingozi yaseTshayina enenombolo ye-UN engama-2929. Umda wokuvezwa emsebenzini ubhekisa kwimigaqo ye-GBZ 2.1-2019, kwaye umndilili ovunyiweyo woxinzelelo oluvumelekileyo (PC-TWA) yi-5 mg/m³. Umgaqo we-EU REACH ufuna amashishini ukuba angenise isibhengezo sedatha yetyhefu yale nto kwaye uyakwalela ukusetyenziswa kwayo njengezinto zokuhombisa. Umgangatho we-US OSHA umisela ukuba izixhobo zokuhlamba ezingxamisekileyo mazifakwe kwindawo yokusebenza, kwaye umgama ukusuka kwindawo yokusebenza akufuneki udlule ukuhamba ngemizuzwana eli-10. I-Hydroxyethyl Acrylate (HEA).

Ulwakhiwo lwe-hydroxyethyl acrylate HEA lugqiba ukuba ine-polarity ethile. Ngenxa yomahluko kwi-electronegativity yee-athomu ezahlukeneyo kwi-molecule, ukusasazwa kwetshaja akulingani. Le polarity ivumela ukuba idibane kakuhle nezinye izinyibilikisi ze-polar, ezifana i-ethanol kunye namanzi.
