The pre-lacquer sanding process that determines the surface quality of wood veneer products

Material is the material premise of furniture. There are many kinds of materials used in furniture design. With the rise of custom-made furniture, there is a class of materials that are deeply loved by designers and consumers in terms of processing technology, appearance quality, physical and chemical properties, and surface decoration, leading the furniture trend.

This material is widely used in home customization, and it is veneer. It is a kind of natural wood or craft wood sliced into thin slices of relevant thickness, adhered to the surface of plywood, and then hot pressed into a surface material for interior decoration or furniture manufacturing.

The emergence of veneer has well relieved the pressure of the shortage of timber resources in our country, and has improved the utilization rate of timber. Although the wooden veneer is very decorative on the appearance of the furniture, its processing and coating need to be sanded many times, which is a time-consuming and laborious process. The quality of the sanding directly determines the quality of the wooden veneer product . Surface Quality.

The polishing process of veneer mainly has the following three aspects:

1. Base material thickness-fixed sanding and substrate surface sanding treatment.

According to the accuracy, quality and surface conditions of the substrate, the fixed-thickness sanding, surface fine sand or surface dust removal treatment will be arranged.

2. Fine sanding after covering with veneer.

Although the substrate has been standardized, the wood veneer still needs fine sanding to remove the overlap and glue marks of the wood veneer.

3. Polish the paint before painting.

The amount of fine sanding is small, and the grinding accuracy is high. The amount of grinding is controlled at about 0.05mm.

The sanding process runs through the entire veneer furniture production process. Among the above three links, an important part is the polishing treatment before painting, which consolidates the pressing degree of the veneer and determines the quality and beauty of the finished product.
