Pitch-wood-wool plate production process

Abstract

The invention belongs to the technical field of pitch-wood-wool plate production processes and provides a pitch-wood-wool plate production process. The pitch-wood-wool plate production process comprises the following steps of material selection, wherein firewood with the diameter greater than or equal to 30 mm and the breakage percentage and the worm damage percentage smaller than or equal to 15% is selected, and impurities in the firewood are removed; slicing, wherein the selected firewood is sequentially sent into a slicing machine to be machined into wood pieces; wool grinding, wherein the wood pieces are sent into a hot-grinding machine to be machined into wood fibers; impregnation, wherein the wood fibers are added into a pitch impregnation device, pitch is quantitatively supplied by the pitch impregnation device, stirring and mixing are conducted, the temperature is maintained to be 150-170 DEG C, the pressure intensity is maintained to be 0.75-0.9 MPa till the wood fibers and the pitch are fused and impregnated, and the mass ratio of the wood fibers to the pitch is 10: (2.8-3.2); and shaping, wherein pitch-wood fibers which are impregnated completely are pushed to a flat laying machine, after a preliminary plate shape is formed, the pitch-wood fibers are sent to a cold press for shaping and then sent to a hot press for drying, a semi-finished pitch-wood-wool plate is formed, and after cutting, packaging and maintenance are completed, the finished product is obtained. By means of the pitch-wood-wool plate production process, the technical problem that in the prior art, pitch-wood-wool plates are easy to age, and in the use process, the pitch-wood-wool plates go bad easily are solved.

Description

technical field [0001] The invention belongs to the technical field of asphalt wood wool board production technology, and relates to a soaking type asphalt wood wool board production process with good anti-aging performance and no corruption. Background technique [0002] The asphalt wood wool boards in the prior art are ordinary asphalt wood wool boards with a layer of asphalt layer painted on the outside of the wood wool boards, which are not only easy to age, but also easy to rot, and the situation of deterioration after use often occurs. Contents of the invention [0003] The invention proposes a production process of the asphalt wood wool board, which solves the technical problems of the prior art that the asphalt wood wool board is easy to age and is easily corrupted and deteriorated during use. [0004] Technical scheme of the present invention is realized like this: [0005] The production process of asphalt wood wool board comprises the following steps: [0006]...
