Plywood production process steps,
1. Overview
Plywood is a kind of wood board made of multi-layer thin wood, with excellent physical and mechanical properties, widely used in construction, home, packaging and other fields. This article will introduce the production process of plywood steps to help readers understand the production process of plywood.
2.raw material preparation
1. Classification of wood: Choose wood with good quality, reasonable structure, slow growth and uniform thickness as raw materials for plywood, generally using pine, eucalyptus, beech and so on.
2. Cutting: The log is cut into a uniform thin board through the sawing machine, the thickness is generally between 2-4mm.
3. Drying: The thin wood is placed in a ventilated, dry place for natural drying or artificial drying until the moisture content is stable between 8% and 14%.
3.processing and production
1. Finishing: trim the dry thin wood, peel it, remove stains and rotten parts.
2. Glue: evenly coat the trimmed thin wood with anti-corrosion glue, corrective glue, etc., so that the wood is tightly bonded.
3. Drying: Put the coated thin wood into the dryer for hot air drying, to ensure that the water content of the coated thin wood is between 6%-8%.
4. Pressing: Place the thin planks after drying on top of each other in the pressing machine. After high temperature and high pressure pressing treatment, the glue between the planks is cured.
5. Trimming: trimming, grinding, trimming and other links of the pressed plywood, so that the board surface is smooth, no burrs, no damage, etc.
4. Inspection and packaging
1. Inspection: The quality inspection method is used to inspect the plywood, mainly to check the bond strength of the glue and the flatness of the board.
2. Packaging: The qualified plywood is packaged through the packaging machine and stored in a moisture-proof warehouse.8×4 composite board,
【 Conclusion 】
This paper introduces the production process of plywood, including raw material preparation, processing, inspection and packaging. The production of plywood needs to go through a number of strict process steps to ensure its stable physical and mechanical properties, but also need to pay attention to the realization of environmental protection, health, sustainable production process.
