Pehea e kau ʻia ai nā lula a me nā kūlana no ka hydroxyethyl acrylate?

ʻO ka Hydroxyethyl Acrylate (MAIKAʻI LOA) Nā Rula a me nā Kūlana
Ua helu ʻia ʻo Hydroxyethyl Acrylate (HEA) ma ke ʻano he mea ʻinoʻino Class 8 ma ka Papa Kuhikuhi o nā Kemika Pōʻino o Kina me ka helu UN o 2929. ʻO ka palena hōʻike hana e pili ana i nā ʻōlelo o GBZ 2.1-2019, a ʻo ka awelika i ʻae ʻia i ka manawa (PC-TWA) he 5 mg/m³. Ke koi nei ke kānāwai EU REACH i nā ʻoihana e waiho i ka hōʻike ʻikepili toxicological o kēia mea a pāpā i kona hoʻohana ʻana ma ke ʻano he mea maka hoʻonaninani. Ua ʻōlelo ke kūlana US OSHA e pono e hoʻokomo ʻia nā mea ʻauʻau pilikia ma kahi hana, a ʻo ka mamao mai kahi hana ʻaʻole e ʻoi aku ma mua o 10 kekona hele wāwae. Hydroxyethyl Acrylate (HEA).

ʻO ke ʻano o ka hydroxyethyl acrylate HEA e hoʻoholo ai he polarity kona. Ma muli o ka ʻokoʻa o ka electronegativity o nā ʻātoma like ʻole i loko o ka mole, ʻaʻole like ka hoʻolaha ʻana o ka uku. ʻO kēia polarity e hiki ai iā ia ke hui maikaʻi me kekahi mau mea hoʻoheheʻe polar, e like me ʻethanol a me ka wai.
