Fibers of secondary ligno-cellulose materials and their influence on properties of insulating fiberboards

This paper deals with the influence of addition of abraded fiber, as a partial substitute of softwood fibers, on the properties of insulating fiberboard. The fiber used was characterized by fractional composition of fiber length according to McNett (STN 50 0289) using the apparatus for the measureme...

description This paper deals with the influence of addition of abraded fiber, as a partial substitute of softwood fibers, on the properties of insulating fiberboard.

Insulating fiberboards were prepared with different content of abraded fiber.
