How to choose decoration plywood board

  Friends who have decorated the house know that because they do not know how to decorate, they have stepped on countless pits, the goods are not right, and the problems of environmental protection are not up to standard often occur. Therefore, how to choose the plate decoration has become the distress of the decorator. Don't worry! Today, Xiaobian will think what you think, worry about what you worry about, take you to know more about the skills of material selection, and avoid stepping on the minefield in material selection

  Q1: The same color plate, why mine did not use a few years deformation?

Everyone in the selection of plates will look at the color, look at the thickness, look at the finish, etc., in fact, there is a point that we ignore is - substrate! As the "foundation" of the entire home improvement, only by consolidating this foundation, the entire "superstructure" can be more stable. Next, let's take you to understand a few of the most commonly used substrates.

  1. OSB

OSB is generally a sheet of wood, also known as shavings, and then a certain proportion of glue, and then the use of high temperature pressing made of board.

Advantages: ① waterproof and moisture-proof. ② High strength, strong nail holding force, easy processing. ③ Good load-bearing capacity, with strong stability.

Disadvantages: ① installation is more troublesome. ② Rough surface.

Usage Suggestion: It is recommended to be used as a backplane or base plate.

  2. Joinery board

Joinery board is a wood-based board composed of a board core composed of wood strips lengthened along the grain and lengthened horizontally, and both sides of the board core are glued together with veneer or plywood slab.

Advantages: ① Good nail holding force, high strength. ② Sound insulation. ③ Water content is not high, simple processing.

Disadvantages: ① Weak nail grip, poor water resistance. ② The vertical bending strength is poor.

3, multi-layer board

Multi-layer board, made of wood segments cut into veneer or wood square planing cut into thin wood as raw materials, with resin adhesive, and then through the hot press high temperature and high pressure made of three or more layers of plate material.

Advantages: ① Strong pressure resistance, not easy to crack. ② Strong nail grip.

Disadvantages: ① weak deformation resistance.

Use suggestion: Long cabinet door is not recommended.

4. Particle board

Pellet board is a board made of wood particles plus a certain proportion of glue and then pressed at high temperature.

Advantages: ① Strong nail holding ability. ② Strong stability.

Disadvantages: poor moisture resistance.

Usage Suggestion: Not recommended for use in particularly humid areas.

Q2: The same plate, why mine taste more?

The evaporation of air pollutants in the board mainly comes from rubber, which should be said well. Traditionally, the glue used in plate production is trichal glue, and formaldehyde is used in the synthesis of trichal glue. Under normal circumstances, the more rubber the plate is not environmentally friendly, the easier it is to release harmful substances such as formaldehyde. Is there any formaldehyde-free glue? Yes, the more mature MDI glue on the market, the ingredients do not contain formaldehyde.

Q3: With so many grades, how can we choose environmentally friendly plates?

Decoration air pollutants are TVOC, aromatic volatiles, formaldehyde, formaldehyde is relatively small toxicity, why do we pay so much attention to it? Because the volatilization period of formaldehyde is long, it is almost accompanied by the material for a lifetime, which will cause great harm to the body. Of course, in addition to adhering to ventilation to remove formaldehyde, you can also use a higher environmental protection grade sheet.

With the increasing requirements of consumers for environmental protection, in October 2021, the new national standard GB/T39600-2021 "Formaldehyde emission classification of wood-based panels and their products" was implemented, and the formaldehyde emission limit value was graded:

E1 after 0.124 mg/m or less

E0 after 0.05 mg/m or less

ENF after 0.025 mg/m or less

Q4: The novice decorator faces a large number of plates, how to choose?

1, look: whether the surface of the plate is flat, whether the color of the decorative plate is uniform, whether the plate packaging is printed with anti-counterfeiting trademarks, factory information, specifications, etc.

2, measurement: Measure the thickness of the plate, the general thickness deviation of ±0.5mm is normal.

3, Smell: whether there is a pungent taste, if it is cheap do not buy!

4, listen: knock on the surface of the plate, the sound is crisp and clean, the density is relatively high.

5, saw: if conditions permit, you can see the inner core, smooth cross section and no obvious holes, bark filling, etc., then it is a high-quality plate.

When choosing plates, these points must be paid attention to in order to choose the plate you are satisfied with. Of course, the choice of big brands is also very key, you can choose Foryou plate, high quality and environmental protection!
