Regeneration artificial board

Abstract

The invention provides a regenerated artificial slab which is mainly made of timber waste (wood shavings, saw dust and wooden chips), four-side plywood waste of plywood manufacture factories and logistic packaging waste (plywood). The logistic packaging waste is artificially processed into strip-shaped slabs with unified specification, then resin cement is applied to the slabs, and the slabs are formed into artificial slabs under the conditions of high temperature and high stress. The slabs can be made into regenerated artificial slabs with two types of different structures: composite flake boards and edge-strip plywood. The thickness of the regenerated artificial slab is larger than 30mm; the regenerated artificial slab, to which a nail can be driven, can be sawed and can replace a raw wood; the regenerated artificial slab improves the comprehensive utilization rate of timber by 1.8 times, reduces forest resource consumption and waste treatment expense, and can be applied to logistic trays, logistic packages, furniture, decorations, etc. The logistic packaging waste is reutilized as far as possible after resource recovery. The regenerated artificial slab attaches profound significance to the building of a resource-conserving and environment-friendly society.

Description

Technical field

[0001] The invention is a new type of regenerated wood-based panel, which is the reuse of wood processing residues and packaging wastes, and plays an important role in saving forest resources, protecting the environment, saving costs, and promoting the development of circular economy. Regenerated wood-based panels are stable in performance, cheap, practical and widely used, making up for the blank of ultra-thick wood-based panels in my country. Using it on logistics packaging can avoid fumigation / treatment, (free of IPPC) and meet the requirements of green packaging. It can be made into a new type of recycled wood-based panel with multiple styles and sizes, which can be sawed, nailed, glued and veneered.

Background technique

[0002] With the process of economic globalization, the development of China's economy and the demand for international trade, my country's manufacturing and processing industries have increased significantly, resulting in a signifi...

Examples

Embodiment Construction

[0021] see figure 1 , Raw materials for recycled wood-based panels (composite particle boards): wood shavings, sawdust, wood chips, bamboo silk, etc., are mixed evenly with resin glue in proportion, placed flat on a fixed hydraulic mold, and then subjected to high temperature and heavy pressure, (Note: The greater the glue ratio, the heavier the pressure, and the harder the hardness of the composite particleboard.) For example, a small board can be directly pressed into a mold for demoulding without sawing, and a large board should be cut into four sides and then cut into specifications. The finished product can also be sawed into various square bars, square piers, strips, etc. according to the application. (Such as figure 2 )

[0022] The recycled wood-based panels (composite particle boards) can usually be made into the regular dimensions of length × width × thickness as shown in the table below.
