How much do you know about the functional characteristics of phosphorus-based flame retardants?

How much do you know about the functional characteristics of phosphorus-based flame retardants?

Due to its own characteristics and performance, phosphorus flame retardant has been used as a flame retardant for a long time. It not only overcomes the shortcomings of large amount of smoke and release of toxic and corrosive gases during combustion of halogen flame retardant, but also improves the shortcomings of high addition amount of inorganic flame retardant and seriously affects the physical and mechanical properties of materials. Its flame retardant effect is excellent, low smoke, low toxicity, no corrosive gas generation, and has been widely used.

What is the mechanism of action of plastic flame retardants?

What is the mechanism of action of plastic flame retardants?

What is the flame retardant mechanism of plastic flame retardants? 1, produce a gas that can smoothen the flame. For example, antimony trioxide, which reacts with HCL produced by combustion in PVC to produce a smothering gas, that is, antimony nitrogen oxide, which has the effect of flame retardant.

The important property of magnesium hydroxide activity

The important property of magnesium hydroxide activity

The activity is not only an important physical and chemical property of magnesium hydroxide, but also an important index to measure magnesium oxide used in rubber industry. In other words, the heavy substance is pure MgO, while the light substance is xMgO · yMg(OH)2, I .e., basic magnesium oxide. Among them, the percentage of light magnesium oxide plays an important role in the activity.

How is the decomposition rate and particle size of aluminum hydroxide affected by temperature?

How is the decomposition rate and particle size of aluminum hydroxide affected by temperature?

The decomposition rate and particle size are important factors to judge the performance of aluminum hydroxide, and there will be many factors that affect the performance in actual production, such as the production environment, production process, and the quality of raw materials. The decomposition rate and particle size are mainly affected by temperature.

The requirements for the addition amount and ratio of magnesium hydroxide are not exactly the same

The requirements for the addition amount and ratio of magnesium hydroxide are not exactly the same

Magnesium hydroxide is a small material that needs to be added when producing goods. Due to the application of different industries such as industry, medicine, food, etc., it will cause different addition amount and ratio requirements. The effect of magnesium oxide addition on the microstructure and physical and mechanical properties of aluminum magnesium spinel refractories sintered at different temperatures was studied. The results show that the addition of magnesium oxide spinel refractories and pure magnesium aluminate spinel refractories, the sintering of the former is better; if the thermal expansion coefficient of the material must be improved and the strength of the material needs to be improved in the field, the application of this kind of refractories can be promoted.

How can flame retardants effectively avoid fire and ensure safety?

How can flame retardants effectively avoid fire and ensure safety?

Combustion requires three main elements-combustibles, combustion aids (oxygen) and a source of ignition. The process of combustion is divided into heating, decomposition, fire, burning and spreading. If you remove any of these elements, or find a way to control the combustion process in the embryonic stage of heating and decomposition, you can effectively avoid the occurrence of fire. Here to introduce the principle of flame retardants, we hope to help.
