Abstract

Today, the main quality criterion in the production of fiberboards is a uniform supply of mixed wood fiber slurry to the mesh part of the press using a high pressure headbox. The interaction of water, various inclusions of waste water, wood-fiber semi-finished product, as well as stainless steel provokes occurrence of chemical reactions that cause intense corrosive destruction of working parts of the inlet. At present, the study of corrosion of the inlet structure pursues the goal of determining characteristic factors caused by the aggressive environment arising at the time of mixing the wood-fiber suspension with the water flow. The analysis of fiberboard production by the wet method examines the possibility of introducing equipment designed for high-quality water treatment with the possibility of cleaning it from various impurities. Pulsar water treatment system is designed for oxidation of soluble metals with their conversion into filterable forms, cleaning from organic and inorganic contaminants due to filters of soft and coarse cleaning using AS sorbents. The station operates autonomously with control of the output gravity for up to 10 years with annual losses of no more than 10% of filter elements.
