Fire retardant treatment process for wood

Abstract

A fire retardant treatment process for wood comprises the following steps: firstly, preparing a fire retardant solution 1 and a fire retardant solution 2; then putting the wood into an immersion tank; then vacuumizing the immersion tank to form negative pressure in the immersion tank; then using the negative pressure in the immersion tank to pump the fire retardant solution 1 into the immersion tank; then pressurizing the immersion tank to ensure that the fire retardant solution 1 is immersed into the wood as deep as possible; then discharging redundant fire retardant solution 1 into a fire retardant solution 1 storage tank; after that, vacuumizing the immersion tank to form negative pressure; then using the negative pressure in the immersion tank to pump the fire retardant solution 2 into the tank; then pressurizing the immersion tank to ensure that the fire retardant solution 2 is immersed into the wood as deep as possible; then discharging the redundant fire retardant solution 2 into a fire retardant 2 storage tank; then taking out the well immersed wood; and finally, drying the wood to complete the fire retardant treatment for the wood. According to the fire retardant treatment process for wood, the fire retardant efficiency is high, the fire retardant solution in the wood can be effectively prevented from losing, the smoke and poison gas in the wood can be inhibited from releasing in a fire disaster, and the fire retardant treatment cost for the wood is low.

Description

technical field [0001] The invention relates to a flame retardant treatment process, in particular to a wood flame retardant treatment process. Background technique [0002] Wood is widely used in furniture manufacturing and interior decoration. However, wood is flammable, and many fires start and spread with wood. With the increasing number of high-rise buildings, the fire is increasing the harm to people. Therefore, the flame retardant treatment of wood is related to the needs of people's life and property safety. [0003] Flame retardant, detection, fire extinguishing and smoke control are important links in fire control. While improving the fire protection function and fire protection infrastructure, prolonging the fire resistance time of non-combustible structural materials, reducing the flammability of materials, slowing down the burning speed of combustible materials, and reducing the amount of smoke produced are valuable for preventing fires and winning the initia...

Problems solved by technology

However, the formaldehyde in the flame retardant treatment process has the problem of formaldehyde release endangering the environment and human health during soaking treatment and wood processing and use. After the first immersion and ultrasonic treatment, the wood needs to be taken out and dried before the second immersion and ultrasonic treatment. The process is more cumbersome, which leads to low efficiency of wood flame retardant treatment.
