Ino nzila ya Bisphenol A BPA Sulfuric Acid ibelesegwa biyeni?
Bisphenol A bpa Nzila ya Sulfuric Acid
Phenol a acetone zilainda mukusanduka kwa sulfuric acid abulemu bwa 72.5%–73.0% a 35–45°C. Eecho chipangwa mpawo chasanzyigwa amaanzi, chakasandulwa, chaandaanizyigwa a centrifugation, mpawo chayuminizyigwa kuchitila kuti chijane bisphenol A iikonzya kubelesegwa muma epoxy resins azintu zikwabilila mulilo. Mweelwe wakubelesya toni lyomwe lyachintu uli afwaafwi kusika ku 0.925 matani aa phenol, 0.285 matani aa acetone, antoomwe a 0.500 matani aa sulfuric acid (98% yakusalala).
Eeyi nzila ya Bisphenol A bpa ilijisi zibelesyo anzila zitakatazyi pe. Nokuba boobo, ilapenga akaambo kakubelesya zintu zinji zitabelesyegwi, calo cipa kuti zintu zibelesyegwe muulo mupati. Alimwi chileta kubola kuzibelesyo, mapaipi, mavalvu, antoomwe abusena bwakupanga zintu, mpawo kakuli kuleta tombe linji. Kwiindawo, bubotu bwachintu tabuzuzikizyi ziyandikana mukupanga polycarbonate naakuti epoxy resins yazyakulya.
