Intshayelelo
ukwazisa
sebenzisa
Isetyenziselwa ukwenza izinto ezahlukeneyo zepolymer, ezifana ne-epoxy resin, i-polycarbonate, i-polysulfone kunye ne-phenolic unsaturated resin. Ikwasetyenziswa ekwenzeni i-polyvinyl chloride izinzisi zobushushu, irabha i-antioxidants, i-fungicides yezolimo, i-antioxidants kunye ne-plasticizers yeepeyinti kunye neenki, njl.
ukhuseleko
Idatha ethembekileyo
Ubuthi buncinci kune-phenols, kwaye yinto ephantsi-ityhefu. impuku yomlomo LD50 4200mg/kg. Xa unetyhefu, uya kuziva ukrakra emlonyeni, intloko ebuhlungu, ukucaphuka kwesikhumba, umgudu wokuphefumla kunye ne-cornea. Abanini-zithuthi kufuneka banxibe izixhobo zokukhusela, izixhobo zokuvelisa kufuneka zivaliwe, kwaye indawo yokusebenza kufuneka ibe nomoya ofanelekileyo.
Ipakishwe kwimigqomo yeplanga, amagubu entsimbi okanye iingxowa ezifakwe kwiingxowa zeplastiki, kwaye ubunzima bomphanda ngamnye (ingxowa) yi-25kg okanye 30kg. Kufuneka ingatshi, ingangenwa manzi kwaye ingaqhubi ngexesha logcino nothutho. Kufuneka ibekwe kwindawo eyomileyo nengena umoya. Igcinwa kwaye ihanjiswe ngokuhambelana nezibonelelo zeekhemikhali eziqhelekileyo.
Intshayelelo emfutshane
I-Bisphenol A (BPA) yi-organic compound. I-Bisphenol A yinto eqinileyo engenambala ukuya kumthubi kwaye iyanyibilika kwizinyibilikisi zendalo ezifana neeketoni kunye neeesta.
Indlela eqhelekileyo yokulungiswa kwe-bisphenol A kukusebenzisa i-condensation reaction ye-phenols kunye ne-aldehydes, ngokuqhelekileyo isebenzisa i-acidic catalysts. Ngexesha lenkqubo yokulungiselela, iimeko zokusabela kunye nokukhethwa kwe-catalyst kufuneka kulawulwe ukufumana iimveliso ze-bisphenol A ezicocekileyo.
Ulwazi ngoKhuseleko: I-Bisphenol A ithathwa njengetyhefu kwaye inokuba yingozi kwindalo esingqongileyo. Uphononongo lubonise ukuba i-BPA inokuba nefuthe eliphazamisayo kwinkqubo ye-endocrine kwaye icingelwa ukuba ibe nemiphumo emibi ekuzaleni, kwi-nervous and immune systems. Ukubonakaliswa kwexesha elide kwi-BPA kunokuba nefuthe elibi kuphuhliso lweentsana kunye nabantwana.
