Particle board easily absorbs moisture, and even when exposed to minimal moisture, may quite literally disintegrate. At the very least, exposure to moisture can cause particle board to shrink and expand, and to warp and bend, which is of course not ideal.
You should be thinking “Does particle board warp over time?”
A large piece of solid wood, such as a tabletop made from one wide board, may warp over time, as many woods expand and contract with changes in the humidity. Aside from generally being less expensive than a similar piece made of solid wood, particle-board furniture does have a few positive traits.
While I was writing we ran into the inquiry “Can MDF boards warp?”.
Some believe that one of the biggest woodworking myths is the idea that MDF boards cannot warp. Sure, this manufactured wood can shrug off a bit of moisture. However, MDF is not water-resistant. And it’s core material is still made from hardwood and softwood composites. Now, we all know that wood likes to move around if its exposed to a bit of water.
Does particle board expand and contract?
Aside from generally being less expensive than a similar piece made of solid wood, particle-board furniture does have a few positive traits. It will not warp, expand or contract like real wood, as long as the original laminate finish is still intact. It is quite durable under regular use and doesn’t dent as easily as some soft wood such as pine.
During expansion, the spaces between the particles get bigger, and during contraction, the spaces between the particles get smaller. How can a piece of metal get bigger (expand) and still have the same mass? Explain this in terms of the behaviour of the particles., and [2 marks].
How do you make particle board?
When to apply a sealant on the board. When you think the board is prone to wet in the rain. If there is a chance to get overheat. If the board needs to carry weight. If you are going to place a new board in a potential area. To enhance the internal decoration of your room. When it is getting damaged. To reuse the particle board.
There are different grades of particleboard. The best is termed as furniture board because it is furniture grade. Fine and strong, particleboard holds a screw better than plywood because it is denser and the material is not as vulnerable to expansion and contraction.
Can particle board be used outside?
Particle board should never be used for outdoor applications, because it will not withstand the moisture from rain or snow for long. Dealing With Particle Board Water Damage Once you see signs of particle board water damage, you will most likely have to replace it. Wet particle board provides a fertile ground for mold and mildew.
Another common inquiry is “Why is particle board furniture bad for the kitchen?”.
Regular exposure to moisture and humidity can cause particle board furniture to warp and expand. This low level of water resistance is a serious liability in the kitchen, especially if you have cabinets located above the stove, near the sink, and other areas that create humidity.
Easily damaged by water. Tends to warp. Not as strong as solid wood. Lacks natural good looks. Difficult to judge the quality.
