Wood Chipboard OSB

1. What is OSB/3 – Oriented Strand Board?

Definition:

OSB stands for Oriented strand board, which translates as wood chips. The material that makes up this product is 80-90% wood chips combined with glue. The type of glue used is usually Urea Formaldehyde glue.

OSB/3 wood chipboards are divided into 5 types corresponding to 5 (from 0 to 4) levels of mechanical features and relative moisture resistance in which OSB/3 wood chipboards are the type that can withstand and be used in wet conditions.

OSB/3 wood chips are composed of thin pieces of wood that are folded and pressed under high temperature and high pressure along with adhesive components.

OSB/3 Global Oriented Chipboard is a wood-made product in the form of a plank flattened by rectangular pieces under the influence of high pressure and temperature, using special glue components and paraffin emulsion. OSB/3 Global-oriented chipboard is a wooden plank that takes advantage of input materials from forest maintenance pruning, products imported from Europe.

2. Lịch sử ra đời của ván dăm định hướng Toàn Cầu osb/3

The origins of wood-based materials dates back to the 1940s when chipboard manufacturing technology was developed. Armin Elmendorf is considered a pioneer of new technology.

• The 1960s saw the development and production of a wood-derived plank called a waferboard. The product is made from pieces of compressed wood, size 25 x 45 mm, arranged in different directions. .
• In late 1970, osb games were first introduced to the construction market.
• In 1980, OSB production in North America was nearly 70 million m2.

3. Structure of OSB wood planks

• Wood chips account for 80-90%
• Phenol Formaldehyde (PF) or Melamine Urea Formaldehyde (MUF) glue accounts for the remaining 5-10%
• Depending on the purpose of use, these types of boards will have additional water or other components. But in general, to assess whether OSB wood planks are of quality, most still rely on the quality of wood chips.

4. Production process

Have you ever wondered how the manufacturer created these OSB wood planks? The way isn’t really that difficult.

Step 1: Mix the glue into the wood chips with the available ratio.

Step 2: Cross-orient the mixture and compress it with the force of high pressure and temperature.

Step 3: Check the hardness as well as durability of this plank has met the requirements and then switch to the sanding machine. The sanding machine helps the product have a smooth, beautiful flat surface.

5. Classification of OSB wood chipboards

To classify OSB wood chipboard, we can rely on a lot of factors. Includes composition, size or wood chips.

• Categorized by composition:

If divided by composition, OSB wood chipboard will be divided into 2 main types: ordinary chipboard and OSB-oriented wood chipboard.

In particular, chipboard is usually made up of wood chips (85%), UF glue (10% – 15%). The rest are water and hardener.

As for osb-oriented chipboards, there is a more improved structure. Specifically, 95% are wood chips and only 5% are glue. OSB-oriented chipboards do not contain water and hardeners. Therefore, customers often use this type of board rather than regular OSB boards.

• Categorized by size and thickness:

Based on the size and thickness of osb wood chipboards are also divided into different types.

As with industrial wood, the size and thickness of OSB wood chipboards can vary according to customer requirements. Therefore, if classified according to this factor, there will be many types of OSB wood chips with different sizes.

It is known that the standard size of OSB wood chipboard is 1220 x 2400 mm. Or you can choose other sizes as required.

The thickness of the board can be 9mm, 10mm, 11mm, 15mm and up to 18mm.

• Categorized by type of wood chips

The last classification we want to talk about is based on wood chips.

The wood chips of OSB wood chipboard can be shaved from rubber trees, pine, peach sinuses, hybrid glue … Therefore, based on the material of chips, it can be classified into OSB board of peach wood chips, OSB rubber chip …

6. Pros/Cons:

Any line of industrial or natural wood has its pros and cons. Therefore, OSB wood chips are no exception.

Any line of industrial or natural wood has its pros and cons. Therefore, OSB wood chips are no exception. Some of the pros and cons of OSB wood chipboard must be mentioned including:

Advantages of Osb wood chipboard:

The reason, OSB wood chipboard is widely applied around the world thanks to the following advantages:

• High durability:

Due to its composition made from natural wood chips and glue, OSB wood chipboard, especially OSB-oriented chipboard is highly durable.

In addition to the above advantages, OSB wood chipboards are also noted for good screwing ability, good load resistance and external force impact. Each nail and screw can stick firmly on the plank for a long time.

• Moisture resistance, good heat resistance:

Also because of its sturdy structural characteristics, OSB wood planks are well water resistant. So, you can use for buildings with high humidity without mold and termites.

OSB wood planks are also known for their high heat resistance advantages. So do not warp, crack in harsh environment. Therefore, the choice of OSB wood chipboard for outdoor works is extremely wise

• Eco-friendly:

OSB wood chipboard does not emit too much formaldehyde so it is very safe to use and environmentally friendly

• High aesthetics:

OSB wood chipboard has a natural, rustic wood grain surface so it will ensure high aesthetics. Not only that, the plank is seamless so you can create grooves or polish. It makes the plank more unique and eye-catching.

With this advantage, OSB wood chipboard can be used for both interior and exterior architecture.

• Affordable price:

OSB wood chipboard is durable, good quality but relatively good price. It is known that this wood line costs less than many other industrial wood lines.

Therefore, you can use it without worrying about the cost.

Osb Wood ChipBoard Cons

The first disadvantage of OSB wood chipboard is that it is difficult to paint color. Because the wood surface is quite complete, glossy and smooth, it is difficult to stick to the color.

In addition, when OSB wood chips if damp, it will take a lot of time to dry. However, this disadvantage does not affect the quality of the board much. Currently, OSB wood chipboard before being put on the market will be scanned water resistance on the side of the plank.

Therefore, despite the unusual quality of wood chips and glue, the quality of the planks is still guaranteed.
