[Chinese wardrobe net] [Wooden question] What is the MDF in the wardrobe sheet?

[professional answer]

MDF is a type of MDF, including long-fiber boards and short-fiber boards. An artificial board made of wood fiber or other vegetable fiber, which is crushed, separated by fiber, dried, and then urea-formaldehyde resin or other suitable adhesive is applied, and then hot pressed. The density is generally in the range of 0.5-0.8 g/cm 3 (the density of the mass pass is not less than 0.72 g/cm 3 ), and the thickness is generally 3-30 mm.

use:

Because of its excellent performance and an effective way to comprehensively utilize and rationally utilize wood, medium density fiberboard is one of the most promising products.

Features:

1. The internal structure is uniform, the density is moderate, the dimensional stability is good, the deformation is small, and the physical and mechanical properties are moderate.

2. The surface is smooth and smooth, and the machining performance is good. The thin wood, pattern and novel and beautiful decorative paper can be pasted on it, so it is deeply loved by people in home decoration, and is often used to make furniture and partitions.

3. It can be applied to the middle border and middle clips of painting in modern decorative frameless paintings. The national registered trademark visual life frameless painting is the application to make life more environmentally friendly.

Precautions:

1. Check whether the thickness and density are uniform, whether the corners are damaged, whether there are delamination, bulging, carbonization, etc., and whether there is a soft part.

2. When conditions permit, a small piece of medium density fiberboard can be sawed in water with a water temperature of 20 ° C for 24 hours to observe the thickness change, and observe whether there is a small drum kit on the board surface. The thickness varies greatly, and there are small drums on the board surface, indicating that the board surface is poor in water resistance.

3. Select medium-density fiberboard with low release. When using olfactory smell, choose medium-density fiberboard with low odor. Because the smell is bigger, the higher the formaldehyde emission, the greater the pollution.
