What is the principle of high temperature aluminum hydroxide preparation?

Presumably, many friends are very interested in the principle of high-temperature aluminum hydroxide preparation. This is indeed a key and difficult work. Next, I will introduce some related content to you, and you can read it carefully.

Presumably many friends for the high temperaturealuminum hydroxideI am very interested in the principle of preparation. This is indeed a key and difficult work. Next, I will introduce some related content to you. You can read it carefully.
1. Generation of high temperature heat stable compounds:
The compound LaAlO3 is a thermally stable calcium titanium type compound. After the low-temperature activated alumina is generated, the thermally stable LaAlO3 is first generated at the edges and corners of the activated alumina lattice. Therefore, a small amount of La2O3 can effectively improve the heat resistance of alumina.
2. Preparation of high temperature hole expanding agent:
In order to improve the activity of high-temperature alumina, in the preparation process of high-temperature alumina, the commonly used expansion agent decomposition temperature is about 300 ℃, the decomposition temperature is too low, so the appropriate high-temperature expansion agent is very important for the preparation of high-temperature alumina. The complex of EDTA and lanthanum, H[La(EDTA)]16H2O, can be completely decomposed by ED2TA above 800 ℃, effectively improving the activity of alumina.
The above is some knowledge about the principle of high temperature alumina preparation, you can refer to it. Today's content is introduced here, I hope to help you, want to know more knowledge can continue to pay attention to us.

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.

What are the reasons for the failure of flame retardant after adding aluminum hydroxide flame retardant?

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.
