Technique for producing fir core plate three-layer wooden composite floor

Abstract

This is a processing method of a triple layer fir wood multiplex floor. Water contend is 11-13% for face board, 8-10% for base board and 11-13% for middle board. During cold gel pressing, gel coating amount is 180-220g / m2 for face board, and 260-300g / m2 for base board. Solidify agent amount is 10-15%. Standing time is 20-50 minutes. Cold pressure is 10-15kg / cm2.

Description

technical field [0001] The invention relates to a production method of a solid wood composite floor, in particular to a production method of a fir core board three-layer solid wood composite floor. Background technique [0002] The current three-layer solid wood composite floor generally uses pine as the core board. However, due to the slow growth of pine, a long growth cycle, relatively scarce resources, and high prices, the contradiction between the supply and demand of raw materials for solid wood composite flooring has intensified, resulting in higher product costs for flooring manufacturers. And fir is a kind of fast-growing wood, which grows fast, has a short growth cycle, is rich in resources, is cheap and has good flexibility. Using fir as the core board of the three-layer solid wood composite floor can greatly reduce the production cost of the enterprise, enable the enterprise to produce cheaper products, and be in a favorable position in the market price competiti...

Problems solved by technology

But Chinese fir is a kind of soft material with low density and poor material stability. When Chinese fir is used as the core board of three-layer solid wood composite flooring, warping and deformation often occur, and the deformation ratio is relatively large, which affects the product. The quality of the product increases the defect rate of the product, affects the business performance of the company, and also increases the difficulty of subsequent processing in production.
