                      Properly store tetrabromobisphenol A

                       Due to the influence of temperature, humidity and other environmental factors, other chemicals, including tetrabromobisphenol A, can easily decompose after being heated to release oxygen, even oxygen atoms, which can oxidize other substances and release a lot of heat.
                      If the ventilation is poor and the heat does not dissipate, the temperature will rise, which will speed up the oxidation rate, generate more heat, and promote the temperature to continue to rise. When the temperature reaches the spontaneous ignition point of the material, the material will ignite spontaneously.
                      There are also many substances with low self ignition point, such as yellow phosphorus (self ignition point is 30 ℃). If they are not properly kept, they can spontaneously ignite in the presence of air when the temperature in summer exceeds the self ignition point.
                      Tetrabromobisphenol A has always been an indispensable chemical raw material in production and life. Generally, manufacturers use bottled packaging. Do you know how to store bottled products? Proper storage techniques are important.
                      The finished product tetrabromobisphenol A shall be sampled and tested in the chemical room. After passing the test, tetrabromobisphenol A shall be sealed in bottles.
                      The packaging shall be carried out according to the specified quantity through measuring bottles, and the error must be controlled within an appropriate range.
                      Before packing and storing Tetrabromobisphenol A, it is necessary to strictly check whether the package has sand holes and cracks to ensure that the finished product will not have any leakage.
                      Label the bottled products with packaging labels for identification.
                      The warehouse uses non thermal conductive refractory materials as the thermal insulation layer of the roof and wall, and appropriately lengthens the eaves to prevent sunlight from entering the warehouse.
                      At the same time, measures such as classification, warehouse separation, piece separation and shelf separation shall be taken for storage, and it is prohibited to conflict with each other in various properties. The stacking shall not be too high, too large, or too dense. A certain distance shall be kept between the stacking and the stacking, walls, columns, roof beams, and electric lights. Fire fighting passages shall be reserved, and excessive storage is not allowed.
