Problems solved by technology

[0002] Flame-retardant wood-based panel is a board type with high technical content in the wood-based panel industry. At present, there are only flame-retardant plywood and flame-retardant fiberboard in the industry. Flame-retardant particleboard is a difficult problem in the industry. Particleboard, and the physical properties of the product are poor, and secondary processing is difficult; with the strict requirements of the country's fire safety, the market demand for flame-retardant products is increasing. The particularity of the particleboard production process, the flame retardant board appears in the production process, the flame retardant performance is unstable, the slab has high moisture content, hot-pressed explosive board, low internal bonding, poor moisture resistance, rough and uneven board surface, and cannot be re-used Processing and other industry problems

Embodiment Construction

[0022] Below in conjunction with embodiment the present invention is further described.

[0023] A kind of production technology of flame-retardant particle board, its processing step is as follows:

[0024] The first step: chipping, use the 2113 drum chipper to cut the selected branch wood into wood chips, the length of the wood chips is 10-50mm, and the width is 10-40mm;

[0025] The second step: shavings, using a ring-type flaking machine to prepare the shaved wood chips into shavings with a thickness of 0.5-1.2mm for use in subsequent processes;

[0026] The third step: drying, sending the shavings into a single channel for drying once, so that the shavings are dried to a moisture content of less than 2.5%;

[0027] The fourth step: Screening, the dried shavings are screened to obtain qualified surface core layer materials, and at the same time, the oversized shavings are sent to the grinder, and the fine dust materials are sent to the heat center for combustion;

Abstract

The invention relates to a production process of a fire-retardant particleboard. The process comprises the following steps: cutting into pieces; flaking; drying; sieving; winnowing; making and applying glue; paving; pre-pressing to form; thermally pressing; cooling a plain board, and stacking; then intermediately storing and transporting; sanding; sawing; and finally packaging and warehousing. The fire-retardant particleboard produced by the process has the characteristics of being stable in process, stable in internal performances, damp-proof, hard to break, environmentally friendly, and easy to secondarily process.
