Pre-Treatment of Vegetable Waste in the Production of Composite Materials

Abstract

Currently, the use of technogenic raw materials, including wood waste is one of the trends in manufacturing of building materials. This is due to the limited resources, the need for long-distance transportation, the high material and energy cost of some technological processes of raw materials extraction and processing. All of them greatly hamper the development of the industry of building materials based on natural resources. Different cellulosic fillers of vegetable origin are used for the production of wood-cement compositions at the moment. Organic fillers along with the inherent valuable properties have a number of specific properties which have a significant effect on the processes of structure formation, structural-mechanical and construction properties of composites. The results of the research of the processes of water-soluble components removal from raw wood material are presented in the article. Processing of raw wood material was carried out in water and weak alkali solution in the research process. It is established that additional ultrasonic treatment considerably intensifies and increases the extraction of water-soluble sugars. The conducted research shows the possibility of improving the composite wood materials manufacturing technology with the aim of improving their performance without significant capital investments.
