Five-point detailed instructions for the use of wood flame retardants
Instructions and precautions for use of wood flame retardant with wood preservative function: 1. Pressure infusion: pressure is not less than 1mp, time is not less than 8 hours, absorption is more than 50kg/cubic meter, ACQ can be prepared into a solution with a concentration of 1-1.5% (1:8-10 mixed with water).

1. Pressure infusion: the pressure is not less than 1mp, the time is not less than 8 hours, and the absorption amount is more than 50kg/cubic meter. ACQ can be prepared into a solution with a concentration of 1-1.5% (1:8-10 mixed with water).
2. Soaking treatment: place the wood in a soaking tank filled with wood anticorrosive flame retardant for a normal pressure soaking time of not less than 48h and an absorption of 100-150kg/cubic meter. ACQ can be prepared into a 2% concentration solution (1:6-8 mixed with water).
3. Brushing treatment: it should be brushed for more than three times. After the first time is completely dried, it should be coated for the second time without missing coating. The absorption amount should be greater than 0.5kg/㎡. ACQ can be prepared into a 5% concentration solution (1:2-4). Spraying for 3 times has the best effect.
4.ACQ preservatives have certain irritation to the skin and eyes. The use of this wood preservative should be protected by labor. It is forbidden to contact the skin with liquid medicine. If the liquid medicine is accidentally splashed on the skin, it should be cleaned with a large amount of water. Contact with wounds and oral administration are prohibited.
5. After operation or contact with this kind of preservative, should be washed with water in a timely manner, with ACQ treatment of wood, not for food packaging. ACQ wood preservatives should be stored in a cool, well-ventilated place. Processing waste from wood treated with ACQ can be collected and disposed of in the same way as ordinary garbage. Because ACQ wood preservatives are corrosive to materials such as copper, mild steel and electro-galvanized, all equipment and fasteners that contact this preservative should avoid the use of these materials, and stainless steel and hot-dip galvanized materials should be recommend.

Zhongke Flame Retardant Organization Watches 20 Closing Ceremonies
On the morning of October 22, 2022, members of Zhongke Flame Retardant New Materials Co., Ltd. watched the closing ceremony of the 20th Congress under the leadership of General Manager Wang Ligui.
Everyone knows that there are two common flame retardants. Today we are going to talk about only one of them. Aluminum hydroxide flame retardant is an environmentally friendly halogen-free flame retardant, which can be widely used in fabrics, wood, plastics, and rubber., Polyurethane and other industries have ideal flame retardant effect. In the process of industrial application, it is found that flame retardant failure occurs when aluminum hydroxide flame retardant is added. The following are the reasons for the failure of aluminum hydroxide flame retardant, how to prevent it, how to deal with the operation, and restore the original function.
As a flame retardant, magnesium hydroxide also need to improve what aspects?
When it comes to flame retardants, everyone is familiar with them. Although we usually have less contact with them, we can know what they are used for from the name. Have to talk about magnesium hydroxide, we all know that its main presentation state is a granular, at present, the market sales of magnesium hydroxide particle size is larger, part of the commodity particle size up to tens of microns, immediately used as a flame retardant, poor dispersion, the physical properties of raw materials greater harm. In industrial production, physical grinding methods are generally used to reduce the particle size to 1 micron. The surface of magnesium hydroxide has high polarity and is easy to agglomerate. As the compatibility of refractory materials and polymer substrates, it not only reduces its flame retardant grade, but also causes more serious harm to the physical properties of raw materials.
