Help you understand more about china plywood part 19: How to understand the Different plywood core veneer structure ratio .

Different plywood core  veneer  structure ratio, will make different quality plywood, the product quality and cost are different.
Therefore, in the production of plywood, we must first determine the price and production costs, and then to determine the specification of each layer core veneer , quality and cost.

不同的芯板单板配比,会做出不同的质量的胶合板,产品的质量和成本都不同的。
所以,在生产胶合板的时候,一定要先把价格和生产成本确定好,然后再去确定每层的规格,质量和成本。

 

What is the ratio of velvet veneer and adhesive in eucalyptus plywood?
Eucalyptus plywood in the proportion of eucalyptus veneer accounted for more than 8 percent, each layer of adhesive is only about 1 kg, the higher the proportion of adhesive Eucalyptus plywood gluing strength is better, eucalyptus veneer compression rate The hardness of eucalyptus plywood is higher.

What is the ratio of eucalyptus veneer and adhesive in eucalyptus plywood?Eucalyptus plywood in the proportion of eucalyptus veneer accounted for more than 80 percent, each layer of adhesive is only about 1 kg, the higher the proportion of adhesive Eucalyptus plywood gluing strength is better, eucalyptus veneer compression rate The hardness of eucalyptus plywood is higher.,

Plywood density and thickness Plywood standard layer there are several?

Plywood is also used in the decoration of one of the materials, there are many types of plywood, plywood density and thickness are a measure of its quality is an important factor. So the decoration materials in the purchase of positioning must pay attention to the plywood is no exception, each material has its different criteria to determine, as long as the master of the standard, buy it is not difficult.
Plywood density and thickness Plywood standard layer there are several?
Plywood is also used in the decoration of one of the materials, there are many types of plywood, plywood density and thickness are a measure of its quality is an important factor.
【Plywood density】
The higher the plywood density, the better the quality. Generally greater than the same kind of wood. The greater the unit pressure when gluing, the greater the density of the plywood. As the wood at high temperature easy to produce plastic deformation, hot glue gluing than the compression of the compression rate is greater. As the plywood from the criss-cross the preparation of the veneer, the thermal conductivity is lower than the same species of wood.
The outermost veneer of the plywood is called a panel, the front panel is called a panel, and the back panel is called a backplate, and the inner veneer is called a core or a plate.
【Plywood thickness】
Plywood is composed of some thin wood chips, there are plywood, plywood, etc., occasionally odd. According to the combination of different layers, the thickness of the plywood is also different, generally 3 PCT board, 5 PCT board, 9 PCT board, 12 PCT board, 15 PCT board, 18 PCT board and other specifications, of course, according to special circumstances will There are other thicknesses.
Plywood thickness and corresponding plywood layers:

Plywood layer of some of the law:
1, plywood thickness for each additional 3mm, the layer will increase by 2 layers;
2, the same thickness of the plywood, the greater the number of layers of strength; such as 15 layer 18mm plywood strength than 13 layers 18mm plywood;
3, the same thickness of the plywood, the more layers the higher the price; such as 7-layer 6.5mm plywood than the price of 5 layers 6.5mm plywood high.
Decoration materials in the purchase of positioning must pay attention to the plywood is no exception, each material has its different criteria to determine, as long as the master of the standard, buy it is not difficult.

Plywood thickness and number of layers

Those who started plywood will encounter this problem. Here I put the number of layers of common thickness plywood as follows:

Thickness
(Mm) the number of layers of plywood
2-3.2 3
3.6 3 or 5
4 5
5.2-6.5 5 or 7
9 7 or 9
12 9 or 11
15 11 or 13
18 13 or 15
21 15 or 17
24 17 or 19
27 19 or 21

Thickness
(Mm) plywood
2-3.2 3
3.6 3 or 5
4 5
5.2-6.5 5 or 7
9 7 or 9
12 9 or 11
15 11 or 13
18 13 or 15
21 15 or 17
24 17 or 19
27 19 or 21
Plywood layer of some of the law:
1, plywood thickness for each additional 3mm, the layer will increase by 2 layers;

2, the same thickness of the plywood, the greater the number of layers of strength; such as 15 layer 18mm plywood strength than 13 layers 18mm plywood;
3, the same thickness of the plywood, the more layers the higher the price; such as 7-layer 6.5mm plywood than the price of 5 layers 6.5mm plywood high. Reason: the more layers the more glue, artificial and production costs are higher, so the higher the price.
Under normal circumstances, the same thickness of the plywood, the more layers the more excellent quality.
