Description

Fire Protection Paint System for Wood and Plywood}

The present invention relates to a flame retardant treatment apparatus for wood and plywood, and more specifically, it is possible to efficiently paint and dry a flame retardant paint on the surface of a flame retardant object made of wood or plywood, and to produce high-quality flame retardant products. It relates to a flame retardant treatment device for wood and plywood.

In general, in the event of a fire, a lot of human damage is caused by high heat and toxic gases, so building materials such as wood or plywood are required to not burn as well as possible and that do not emit a lot of toxic gases in order to prevent human damage in advance. .

In other words, if a fire occurs in wood or plywood (including MDF wood or plywood) that is not flame-retardant, high heat and toxic gases are generated as the wood is burned. Flame retardant coating is applied to the surface of the wood so that it does not spread.

In this conventional flame-retardant treatment method, a flame-retardant solution was thinly applied three times on the surface of a flame-retardant object (wood, plywood, etc.) using a brush or roller. However, the conventional flame-retardant treatment method requires not only about three or more application of the flame-retardant paint, but also requires a flame-retardant treatment time of up to 10 hours or more.

In addition, with the conventional flame-retardant treatment method that simply applies flame-retardant paint to the surface of wood or plywood, a perfect flame-retardant effect cannot be expected in the event of a fire on wood, so great damage is expected. Thus, there is a need for an economical new flame-retardant treatment means that can improve the fundamental flame-retardant performance and flame-retardant durability, shorten the flame-retardant treatment time, and reduce maintenance costs.
