Recycling of Hydrogen Fluoride Production Wastes by Manufacturing on their Basis Acid Fluoride Finishing Sheets

The method of recycling of hydrogen fluoride production wastes – acid fluoride – by processing it into environmentally safe building materials – acid fluoride finishing panels (PANO) is proposed. A continuous laboratory unit designed to produce PANO sheets from neutralised acid fluoride has been developed and tested. The detailed technological scheme of the whole process is presented, including preparation of raw materials, moulding of products in the given geometrical parameters, as well as their subsequent ageing until the required performance characteristics are achieved. The main constructive solutions of the unit are described, due to which the uniform distribution of the initial mixture is achieved. It is concluded that the proposed technology contributes not only to the expansion of the resource base of the construction industry due to the secondary use of technogenic raw materials, but also to a significant reduction in the overall ecological load on the environment.
