Method of manufacturing board with leather by-products and board manufactured by adopting the method

Abstract

The invention relates to a method of manufacturing boards with leather by-products and a board manufactured by adopting the method, especially a gypsum board and a texture board suitable for being used as building interior materials manufactured with natural leather by-products and boards manufactured by adopting the method. According to the method, the shaving scraps of natural leather by-products are beating through physical means and then are bonded by binding materials through chemical means. Therefore, the adhesion, forming performance, shape stability, strength, moisture content, flexural load and the like of fiber materials are improved. Then the material is dried and pressed to be molded into boards.

Description

technical field [0001] The present invention relates to a method for producing boards using natural leather by-products and the boards produced by the method, and more particularly to a method for producing boards using natural leather by-products that can be suitably used as gypsum boards and texture boards for building interior materials Method and panel manufactured according to the method. Here, it includes the process of physically crushing shaving scrap (Shaving scrap) which is a by-product of natural leather, and then chemically bonding it with binding materials, thereby improving the fiber bond. Bonding force, formability, shape stability, strength, bending failure load, etc., are dried and pressed to produce a board. Background technique [0002] Recently, the problem of environmental pollution due to waste has become more and more serious. [0003] The main reason for the environmental pollution caused by various wastes is that the wastes cannot be recycled by in...

Problems solved by technology

[0007] In order to solve the above problems, when the cutting waste (Shaving scrap) is short-fiberized and then dehydrated in the paper machine to make the board meet the appropriate strength, thickness, hardness, etc., due to the weakening of the dehydration force, there will be a gap between the fibers. The binding force of the board is low, and secondary pollution is caused by the use of excessive chemicals, so it cannot meet the thickness, strength, and hardness required by the board

[0008] And, the existing method as mentioned above is suitable for the process of producing flakes and soft products, so it is not suitable for manufacturing products with higher strength, hardness and thickness.

Moreover, the binder used has limitations in improving the binding force between fibers, thus causing poor product performance and environmental pollution
