Use of irretrievable waste flax and cotton for production of heat-insulating plates

Abstract

In the article the method of utilization of irrevocable waste of spinning of a flax and cotton is considered. It is offered to use waste as filler for production of heat-insulating composite plates. The difficulties of use of irrevocable dust-like waste as filler of composite plates are caused by considerable damage of vegetable fibers, increase in absorbency binding in filler, a big specific surface of particles. The composite materials from dust-like vegetable waste are produced by the technology of fiber boards of a wet way of production. As binding phenol formaldehyde resin is used. Increase in a share of additive of pitch leads to the increase in durability of material. At all modes of production and any share of additive binding stronger are composite materials from dust-like waste of processing of a flax. The mass fraction binding in composite material doesn't exert significant impact on the coefficient of plate heat conductivity.
