Aluminum Hydroxide: Factors Affecting the Filtration Effect of High Temperature Alumina


Aluminum Hydroxide: Factors Affecting the Filtration Effect of High Temperature Alumina

In the process of high-temperature alumina production itself may have some impurities, so it needs to be filtered to filter out these impurities to obtain higher purity products. Today we are going to introduce what factors affect the filtration effect of high-temperature alumina.
1. The viscosity of the slurry.
The slurry viscosity has a great influence on filtration. The higher the slurry viscosity, the slower the high temperature alumina passes through the filter medium, and the more difficult the filtration will affect its filtration effect to a certain extent.
2. Use cycle of filter cloth.
The filter cloth has a short service cycle and the operation rate of the filter equipment becomes lower. Therefore, the filter cloth should be selected according to the actual situation.
3. Filter pressure.
The greater the filtration pressure, the stronger the filtration power, and the faster the filtration of high-temperature alumina.
4. Filter media.
The nature of the filter cloth has a certain influence on the filtration of high temperature alumina. Usually, the larger the filter cloth hole, the easier the filtrate to pass through, and the better the production capacity. However, too large a filter cloth hole diameter will also cause fine solid particles to pass through easily and enter the filtrate.
The physical properties of solid materials will also affect the filtering effect of high temperature alumina. In general, the coarser the particle size of solid materials is, the larger the pore size of filter cake as filter medium is, the easier the filtrate penetrates, the better the filtration performance is, and the solid materials with fine particle size are easy to block the pores of filter cloth. If the pores of filter medium are small, the filtration speed will be reduced.

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.
