& Wood flame retardant Wood flame retardant manufacturer Wood flame retardant price Wood flame retardant is an environmentally friendly flame retardant that does not contain prohibited ingredients such as halogen and heavy metals. This product is a white powder, easily soluble in water, and has flame retardant, Smoke suppression, anti-corrosion and anti-termite properties. This product is non-toxic and tasteless.
Configuration of treatment liquid
The ratio of this flame retardant to water is generally::. (It is recommended to be greater than:). For wood that is difficult to flame retardant, it is recommended to use a higher concentration of flame retardant treatment liquid. .
B. Flame retardant treatment of wood
Vacuum and pressure treatment is generally used. Usually the first vacuum time is minutes. Most broad-leaved forests (such as birch, basswood, and elm)
The pressing time is minutes and the pressure is .megabytes. The immersion time of Korean pine is hours, the pressure is . MPa, and the immersion depth is mm.
The treatment liquid after each treatment can be recycled, and the concentration of the treatment liquid does not change due to changes in the number of times the wood is treated.
Introduction to the vacuum high-pressure impregnation method of flame-retardant wood production
. Put an appropriate amount of kilograms of water in the container, add the flame retardant, and stir to dissolve the flame retardant and turn it into a transparent solution
. Put the wood into the high-pressure impregnation tank and close the lid
. Evacuate to ~mmHg and hold for ~min
. Open the valve connected to the flame retardant storage tank and introduce the flame retardant by vacuum. In the high-pressure impregnation tank, when the flame retardant fills the impregnation tank, release the vacuum
and close the vacuum valve
. Slowly pressurize to .~. and maintain for ~ hours
. Flame retardant absorption amount: Dry flame retardant/dry wood = ~%. In advance, take a piece of wood of the same specification, label it, weigh it, and put the sample into the dipping tank and soak it for a period of time, take out the sample, weigh it, and calculate the amount of flame retardant absorbed. If the amount of flame retardant absorbed is insufficient, extend the impregnation time.
. Release the pressure, discharge the agent, close the pressurization valve and the valve connected to the flame retardant storage tank
. Evacuate to ~mmHg and maintain for ~ minutes
. Release the vacuum and take out the wood
.Dry to required moisture content.
