What is the production process of paint-free board

1. Melamine is one of the resin binders for making this board. After soaking paper of different colors or textures in resin, dry it to a certain degree of curing, and lay the decorative board on the wood board or solid wood board. The standard name is melamine impregnated glued paper veneer wood-based panels, saying that the melamine board is actually part of its finishing composition.

1. Melamine is one of the resin binders for making this board.

The standard name is melamine impregnated glued paper veneer wood-based panels, saying that the melamine board is actually part of its finishing composition.

2. The production process of melamine impregnated film paper: glue making (adding curing agent, release agent, etc.). One dipping (melamine formaldehyde resin and urea formaldehyde resin mixture) one drying "secondary dipping" (melamine formaldehyde resin) "secondary drying" cooling cutting.

2. Material and structure of paint-free board

1. The core layer MDF and melamine-coated paint-free boards are not environmentally friendly, cannot hold nails repeatedly, have unbalanced internal stress, and are easily deformed. (2) MDF and melamine-coated paint-free boards have problems such as unenvironmental protection, inability to repeatedly hold nails, unbalanced internal stress, and easy deformation.

2. The paint-free board market is generally easy to open the three-ply plywood core material base material.

3. Although the board core, medium board and melamine paint-free board have strong adhesion and stability, they have high process requirements.

4. Select and classify the wood, classify and store the logs according to the type, diameter, length and use of the wood, and then peel the logs. Generally, mechanical peeling is used to decompose the logs and cut the length required for sawing. Cutting depends greatly on the size and condition of the log, as well as the width and thickness of the wood. After switching, the panels are formed, the panels are sawn into panels, saw blades, and standardized widths are produced as required.

5. If it is precious wood, it will also be graded. This is to separate the wood according to the general appearance of the wood, such as the overall quality, grain direction, knots and defects. After classifying different furniture materials, the impact on the price of the finished product is also very important. big. To protect the wood from fungus and bugs, drying is required to reduce the moisture content to acceptable levels, the price of wood is not affected by weight, and weight reduction can also reduce shipping costs.

6. Check for possible defects in the drying process, such as forks, loose knots, etc. These defects can be removed by trimming, according to market needs, the wood surface can be machine-planed and processed here. Substrate molding of solid wood panels.
