Isingeniso
ethula
sebenzisa
Isetshenziswa ekwenzeni izinhlobonhlobo zezinto ze-polymer, njenge-epoxy resin, i-polycarbonate, i-polysulfone ne-phenolic unsaturated resin. Ibuye isetshenziswe ekwenzeni i-polyvinyl chloride heat stabilizers, ama-antioxidant enjoloba, ama-fungicides ezolimo, ama-antioxidants nama-plasticizers opende noyinki, njll.
ezokuphepha
Idatha ethembekile
Ubuthi buncane kunobuphenol, futhi buyinto enobuthi obuphansi. igundane ngomlomo LD50 4200mg/kg. Uma unobuthi, uzozwa umlomo omunyu, ikhanda elibuhlungu, ukucasuka esikhumbeni, umgudu wokuphefumula, kanye ne-cornea. Abaqhubi kufanele bagqoke izinto zokuzivikela, okokukhiqiza kufanele kuvalwe, futhi indawo yokusebenza kufanele ibe nomoya omuhle.
Ipakishwa emiphongolweni yokhuni, izigubhu zensimbi noma amasaka afakwe izikhwama zepulasitiki, kanti isisindo senetha somphongolo ngamunye (isikhwama) singama-25kg noma ama-30kg. Kufanele ingashi, ingangeni emanzini futhi ingaqhumi ngesikhathi igcinwa futhi ihanjiswa. Kufanele ibekwe endaweni eyomile futhi engenawo umoya. Igcinwa futhi ihanjiswe ngokuvumelana nezinhlinzeko zamakhemikhali ajwayelekile.
Isingeniso esifushane
I-Bisphenol A (BPA) iyinhlanganisela yezinto eziphilayo. I-Bisphenol A iqinile engenambala ukuya kokuphuzi futhi inyibilika kuzincibilikisi zemvelo njengama-ketone nama-ester.
Indlela evamile yokulungiswa kwe-bisphenol A iwukusabela kwe-condensation yama-phenol nama-aldehydes, ngokuvamile kusetshenziswa ama-catalyst ane-asidi. Phakathi nenqubo yokulungiselela, izimo zokusabela kanye nokukhethwa kwe-catalyst kudinga ukulawulwa ukuze kutholwe imikhiqizo ye-bisphenol A ehlanzekile kakhulu.
Ulwazi Lokuphepha: I-Bisphenol A ithathwa njengobuthi futhi engase ibe yingozi emvelweni. Ucwaningo luye lwabonisa ukuthi i-BPA ingase ibe nomthelela ophazamisayo ohlelweni lwe-endocrine futhi kucatshangwa ukuthi inemiphumela emibi ohlelweni lokuzala, lwezinzwa kanye nokuzivikela komzimba. Ukuchayeka isikhathi eside ku-BPA kungaba nomthelela omubi ekukhuleni kwezinsana nezingane.
