  來源:www.21chengdu.cn
With the acceleration of urbanization, the urban population has become excessively concentrated and the demand for various resources has been increasing. Fire prevention has become another top priority task of the municipal party committee and government. Most manufacturers will have a little worry when preventing and controlling. What effective measures should be taken to solve many problems in the whole stage? The root cause of most problems lies in not knowing how to use it to really work.
When tetrabromobisphenol A is used for the first time, a small amount of tests shall be carried out to test the specific performance and whether it is suitable for use. The shake bottle test method can be used, and the operation is simple.
Some industries need to dilute before use. During dilution, tap water without any impurities shall be selected. Hot water shall not be used to avoid demulsification. PH value shall be tested after dilution. Other additives can also be added to help improve the dilution effect.
According to the specific form, the liquid should be added by dropping and spraying, and the solid can be directly put in, so that tetrabromobisphenol A can achieve the ideal effect. The powder shall be added continuously, which can be added regularly by technicians. Add 3 to 5 times of diluent, not more than 10 times.
