Xana Ndlela ya Bisphenol A BPA Sulphuric Acid yi tirhisiwa njhani?
Bisphenol ya A bpa Ndlela ya Asidi ya Sulphuric
Phenol na acetone swihundza eka condensation reaction eka sulphuric acid leyingana mass concentration ya 72.5%–73.0% eka 35–45°C. Kutani xiendliwa lexi xi hlantswiwa hi mati, xi crystallized, xi hambanisiwa hi centrifugation, kutani xi omisiwa kuva xikuma bisphenol A leyi lulameleke general-purpose epoxy resins na flame retardants. Mimpimo ya ku tirhisiwa hi thani ya xiendliwa yi kwalomu ka 0.925 tons ya phenol, 0.285 tons ya acetone, na 0.500 tons ya sulfuric acid (98% ku basa).
Ndlela leyi ya Bisphenol A bpa yi na switirhisiwa swo olova swinene na maendlelo. Hambiswiritano, yi xaniseka hi ku tirhisiwa lokukulu ka switirhisiwa swo ka swi nga tirhisiwanga, leswi endlaka leswaku ku va na ku tlakuka ka ntsengo wa swikumiwa. Switlhela swivanga ku bola eka switirhisiwa, tiphayiphi, ti valve, na ndzhawu ya vuhumelerisi, loko swiri karhi swi humesa nhlayo leyikulu ya thyaka. Ku tlula kwalaho, khwalithi ya xiendliwa ayi fikeleli swilaveko swaku humelerisa polycarbonate kumbe food-grade epoxy resins.
