IMPROVING THE PROCESS OF SPECIAL PURPOSE FIBREBOARD

Abstract

The results of studies of physical and mechanical properties of fiberboard production by dry method (MDF) using presmasse vermiculite concentrate and expanded vermiculite. It was found that the use of vermiculite in the manufacture of the plates produces Fire resistant MDF, fiber savings, reducing the density of the plate, improves durability at a static bend, decreases the cost of the plates.

Object of research – getting fiberboard special purpose dry process production.

Subject of research – the process of preparation of semi-finished products in the preparation of fibreboard with reduced fire hazard.

Objective – To develop the scientific basis of reduce fire danger fibreboard made by dry method.

The process of grinding the wood fiber supply in knife grinding machines depends on their design and process parameters. Morphological properties developed fibers, in turn, also have a significant effect on the properties of the finished product. Since the processes of obtaining Fire resistant boards with the right physical and mechanical properties are currently not enough substantiated theoretically and basically solved in a practical way, in the following tasks:

- Determine the composition of the special manufacturing techniques in presmass Fire resistant hardboard dry process production;

- Determine the effect of flame retardant components and quality characteristics of wood-fiber semi-finished products on the physico-mechanical properties of the finished boards with a reduced fire hazard.
