[ Chinese wardrobe net ] home decoration, wardrobe is indispensable, whether it is to go to the mall to buy brand wardrobe or to ask the woodworker to make, we need to pay special attention to the material of the wardrobe. Let's take a look at the information on the wardrobe sheet.

1. Particleboard (also known as "solid wood particle board") is a piece of wood or other wood fiber material that is cut into a certain size as a raw material. After drying, it is mixed with adhesive, hardener, water repellent, in heat, pressure and certain An artificial board pressed at a temperature.

advantage

The internal part is granular with cross-displacement structure, the performance of each part is basically the same, the lateral load-bearing capacity is good, the amount of glue used is small in the production process, the environmental protection coefficient is relatively high, the surface is flat, the texture is realistic, the weight is uniform, and the thickness error is small. It is resistant to pollution, aging, and beautiful. It can be used for various veneers. The finished product does not need to be dried again. It can be used directly, and the sound absorption and sound insulation performance is also very good.

Disadvantage

The internal structure is granular, it is not easy to be milled, the edge is rough, and it is easy to absorb moisture. It is easy to cause toothing when cutting. Therefore, some processes have higher requirements on processing equipment; it is not suitable for on-site production.

2. MDF (also known as "fibre board") is made of wood material such as trunk material, branch material or other plant fiber, which is thermally ground (grinded into powder), sized (urea resin or other suitable adhesive), An artificial board made by drying and hot pressing after paving.

advantage

Various veneer, adhesive film, veneer, light metal sheet and other materials can be glued on the surface of the MDF; various paints and paints can also be applied on the MDF, the effect is very beautiful, and the hard MDF is punched. System, drilling, can also be made into acoustic board, smooth surface, fine material, stable performance, firm edge, easy to shape, avoiding problems such as decay, insects, etc., excellent physical properties, good nail holding power, uniform material There is no dehydration problem.

Disadvantage

If it is not moisture-proof, it will swell when it sees water, and it will be deformed for a long time.

3. Moisture proof board

The moisture-proof board is to add a certain proportion of moisture-proof particles to the particle board substrate, so that the degree of water swelling of the board is greatly reduced.

advantage

In addition to the advantages of particle board, there is also a prominent advantage is moisture. However, it should be noted that the moisture-proof board and the ordinary particle board are immersed in water, and the expansion ratio is the same. The so-called moisture-proof only acts on the moisture in the air.

Disadvantage

All the shortcomings of particleboard, the moisture-proof board has.

4. Large core board

The large core board (also known as "blockboard" is made of two pieces of veneer laminated in the middle of the board. The middle board is made of high quality natural wood board after heat treatment (ie drying in the drying room). The specification of the wooden strip is made up of the jigsaw machine. The two sides of the spliced ​​wooden board are covered with two layers of high-quality veneers, and then made by cold and hot press. The total of the two sides of the large core board is glued. The thickness shall not be less than 3mm. The corner defects of all kinds of large core plates shall not exceed 5mm in the nominal width and shall not exceed 20mm in length.

advantage

The clamping force is good, the strength is high, and it has the characteristics of firmness, sound absorption, heat insulation, etc., and the water content is not high, between 10% and 13%, and the processing is simple.

The plate of the machine is subjected to a large pressing force, the gap is extremely small, the splicing is flat, the bearing capacity is uniform, long-term use, compact structure and deformation.

Disadvantage

The moisture-proof performance is poor. The hand-stitching is to manually insert the wooden strip into the splint. The wooden strip receives less pressing force, the splicing is uneven, the gap is large, the nail holding power is poor, and the sawing process cannot be sawed. It is only suitable for partial decoration. Sub-projects, such as cushioning boards for solid wood flooring.

The above is the knowledge of the wardrobe sheet, I hope to help you.
