Low-viscosity epoxy bindershazard classreduction

At the present moment the volume of binder industrial waste belonging to hazard class 2 and intended for disposal makes up hundreds of tons per year. Due to its increased toxicity disposal of the binder waste in polymer composite materials production refers to one of the problematic issues in actual practice since its disposal is extremely difficult. The article deals with the results of researches related to reduction of hazard class of epoxy resins used in production for their further disposal. In order to determine the product’s hazard class biotesting methods using Scenedesmus quadricauda Breb. algae and Daphnia magna Straus. daphniae were applied. Epoxy resins mixture wastes hazard class reduction is achieved by filling them with a natural component in the form of starch followed by converting the mixture to solid state in presence of ortho-phosphoric acid.
