Embodiment 1
[0022] In the present embodiment, the production process of the liquid composite type fire extinguishing chemical inhibitor is as follows:
[0023] A, select the formula of flame retardant, the formula of this flame retardant consists of: magnesium hydroxide, aluminum hydroxide, sodium percarbonate, sodium bicarbonate and magnesium chloride, weigh magnesium hydroxide 10g, aluminum hydroxide 5g, sodium percarbonate 3g, 7g of sodium bicarbonate, and 2g of magnesium chloride were dissolved in 37g of water to make a saline solution;
[0024] B. Filter the salt solution with a 600-mesh filter. After the filtration is completed, cool the salt solution to -10°C, and let the salt solution stand for 50 minutes;
[0025] C. After the salt solution left standing in step C has no crystals, add the salt solution into the enamel reaction kettle and heat it. The heating temperature is 62° C. and the heating time is 30 minutes;
[0026] D. Turn on the stirrer, add penetrating agent, suspendi...
