Core-board with new structure and its production process

Abstract

A core-board with novel structure features that its both surface plys and core ply are all the single board with the thickness of more than 4 mn. Its production method includes using the rotating cutter to cut timber for obtaining single board with more than 4 mm of thickness, drying for 1-4 days, gluing their together to obtain three-ply board, abrading both surfaces, and gluing veneer. Its advantages are high utilization rate of timber (80-90%), saving electric energy by 60% or more, simple method, and high performance and quality of product.

Description

Technical field: [0001] The invention belongs to a blockboard product and a production process thereof. Background technique: [0002] The blockboard currently used for interior decoration is composed of small slats of unequal length bonded into a 14.2mm thick core board, a whole 1.2mm, 1.5mm or 1.8mm thick panel and the whole pasting skin. The production process is to process the logs into 55mm-thick and unequal-width squares first, and the yield rate is 65%; then the squares are stacked and dried naturally for 1-3 months, and then dried in a steam kiln or fire kiln About 10 days, the drying cost of square timber is 80-120 yuan per square meter; the dried square timber is planed, planed, multi-bladed saw, and small cut-off saw is processed into small slats, and the yield rate is 58%; Then use small strips to splice the core board, and the side materials need to be finger-jointed. In the middle, use a jigsaw machine to assemble a 1.3×2.5-meter core board. The upper and lowe...

AI Technical Summary

Problems solved by technology

The disadvantages of the above-mentioned blockboard and production process are: because the core boards of the product are spliced ​​together, the use strength of the product and the quality of engineering decoration are affected. Complex process and high cost
