MDFboards have changed the traditional ways of building through technology. They are fiber-based panels that are nonstructural and are composed of wood fibers that result in them having a smooth finish. This is done under pressure and heat and by injecting resin through a process known as bonding. They are used to make furniture such as cabinets and flooring.
Materials Used
Wood fibers from soft and hardwood is broken down into wood fibers. Recycled wood shavings from sawmills and plywood plants can also be used in getting the raw materials you need.The wood fiber which is about 82% is then mixed with 9% resin, water 8% and paraffin wax 1%. This is important to note as it affects the density of the board and its elasticity.
Production Process
In this process, the materials being used are passed through a large magnet where impurities are removed. A pre-steaming bin collects the good material and softens it. Compression also takes place to remove the water and then the materials are passed through a refiner which shreds the fiber. Resin is then added to help in the process of bonding.
Drying Process
After bonding the mixture is put in a large dryer, and oil or gas is used in heating to create a dry combination. This is then compressed to ensure that the right density is achieved. During this process wax and resin are also injected as the last bonding agents to improve the moisture also avoid clumping.
Pressing
This is done in the last stages before trimming. The MDF boards are also allowed to cool and dry during this process until they are ready for storage. A laminationmay also be done to give it extra strength which makes them ready for packaging and finally sale having achieved the quality control standards.
Varieties
- Particle Boards- are made from wood shavings and sawdust from sawmills. They are bonded together using resin to strengthen the board.
- Fiber Boards- they are like particle boards but have a high density. They are also eco-friendly as they are made from organic fiber such as vegetable starch, sugarcane as well as wood chippings.
- Veneered Boards- they can be made in decorative ways to create patterns. This is done using stretching techniques as the boards are flexible and high pressure.
- Laminated Boards- wood fibers are used to manufacture them
Advantages
- Managing them is easy especially in humid places like kitchens and bathrooms.
- Some are resistant to moisture making them good in such environments
- You can change its look by painting
- The Mdf board price in Kenya has made them affordable
- They do not easily crack because of their structure and materials used to make them.
Disadvantages
- They are not good in extreme weather conditions
- Though used as an option when building, they do not support a lot of weight.
- Some can be heavy and may need anchors for extra support.
- Compared to wood they are weak.
- They absorb water so you must be cautious when using them.
Conclusion
MDF boards save time when you need a quick solution. With thediverse types in the market, you canmake a choice.
