Chemical durability of glasses obtained by vitrification of industrial wastes.
The vitrification of zinc-hydrometallurgy wastes, electric arc furnace dust (EAFD), drainage mud, and granite mud was shown to immobilize the hazardous components in these wastes. Batch compositions were prepared by mixing the wastes with glass-cullet and sand to force the final glass composition into the glass forming region of the SiO2-Fe2O3-(CaO, MgO) system. The vitrification was carried ou...
متن کاملChemical durability, specular gloss, and transmittance of optical glasses.
The chemical durability of three types of optical glass (BSC 517, BaC 572, and F 620) and chemical Pyrex llave been studied o\"er an extended pH range by means of an interfe rometer proced ure. The accompanying effect on the appearance (gloss retained) and on the transmittance of the specimens has also been determ ined. The results illustrate the con fu sion t ll at might a rise from choosin g ...
متن کاملThe Effect of Waste Loading and Glass Structural Factors on Structure and Chemical Durability of SB2 and SB4 SRS Waste Glasses
Glassy materials simulating vitrified high-Na/Fe (Sludge Batch 2 – SB2) and high-Na/Fe/Al (Sludge Batch 4 – SB4) Savannah River Site high level wastes (HLW) were produced in a resistive furnace and 236 and 418 mm inner diameter cold crucibles. The effect of waste loading (WL) and glass structural factors (degree of connectedness of glass network, metal oxides to boron oxide ratios) on chemical ...

پلی کربنات یکی از پلاستیکهای مهمی است که به صورت گسترده در تولید لوحهای فشرده، قطعات رایانه، مواد ساختمانی و غیره مورد استفاده قرار می گیرد. این پلیمر بصورت عمده از تراکم مونومر بیس فنولa (bpa) و کربنیل کلرید یا دی متیل کربنات ها بدست می آید. در سالهای اخیر بازیافت شیمیایی پلی کربنات بیشتر مورد توجه بوده است. بازیافت شیمیایی پلی کربنات برای بدست آوردن مواد اولیه آن با روشهای متفاوتی مانند تجزی...
