Wood Preservation Methods
Wood science is the study of wood as a material that is renewable and of biological origin. In other words, the term wood science can also be known as wood technology. Wood is treated as a material in direct comparison with other products. Materials properties, ease of it being worked on and its value are among the few properties which are compared against those of wood and other materials. The utilization of technology gives wood an upper hand in most of this comparison. Some of these advantages include wood being a versatile material that can be used in a wide range of products. It is also based on renewable resources. Timber can be utilized in very many applications, and this makes it more valuable.
Protection of wooden structure and products is a must if you want to keep the good looks in place. This protection is from moisture and insects which are the biggest threat to wood. The rotting and decay of the timber products are caused by the moisture and the insects. Many methods are available in the treatment of wood one of the most common being the ACQ – alkaline copper Quaternary. As the name implies the preservative is made of copper products. There are a few disadvantages of this method as a mode of wood preservation. It has been seen corroding most metals for example aluminum in less than six months of its application. The concentration of the chemical that will be used to treat a piece of wood will depend on the where it is going to be used and the molecular structure of the wood. The concentration level of the chemical will be different for two pieces of wood where one is used above ground and the other close to a water body.
Another wood treating method that is fast being accepted is the use of copper metal. The use of this method is fast being accepted because it is not corroding the metal fasteners. An alternative name to be given to this method is the micronized copper wood preservative method. In this process microscopic particles of solid copper metal are mixed in a liquid carrier and injected to the wood at high pressure. In other copper-based preservation methods copper is dissolved in chemicals while in this method copper is driven into the wood as a metal. When this process is used to treat timber the timber properties are increased highly. The wood products protected using this method last longer.
The micronized copper preservative has proven to be highly effective in protecting the wood against fungal decay and termites. It has also shown to be an improvement in corrosion resistant properties to metal fasteners. The wood treated using this method last longer and is stronger.
