How to clean the residue of aluminum hydroxide container?
No matter in the production or in the use of aluminum hydroxide powder, the container is indispensable, but the cleaning of the container has become a problem. If the cleaning is not good, it will affect the next use, so how to clean it?
Whether in production or in usealuminum hydroxideWhen micro-powder, the container is indispensable, but the cleaning of the container has become a problem. If the cleaning is not good, it will affect the next use, so how to clean it?
Aluminum hydroxide powder container cleaning is mainly through a variety of washing liquid, through physical and chemical methods to remove dirt on the glass, according to the requirements of the test and the nature of the glass and the degree of contamination of different lotions and methods of tap water scrubbing with a brush on the water scrubbing, can make aluminum hydroxide powder dissolved, can also make the dust attached to the surface of the instrument to wash.
When using this method, it should be noted that only a small amount of micropowder in the container can be used, and a large amount is prohibited. After washing with tap water, scrub carefully with soapy water washing powder with a brush. When washing, the dish should be cleaned to produce more foam, then rinsed with tap water, then rinsed three times with cooked distilled water, drained naturally on a drying rack or dried in an oven for later use.
At the same time, if there is a hidden spot of aluminum hydroxide micropowder in the corner of the container that is difficult to clean during the test, water treatment must not be used, because a relatively large amount of micropowder will cause the local temperature to increase rapidly after encountering water, thus causing the container to burst. Use 45% urea solution to dissolve aluminum hydroxide micropowder, and then rinse with water. If it is still not clean, soak it in potassium cleaning solution for 4-6h, and then wash it with water.
If the residue of aluminum hydroxide powder is not cleaned, it may affect the next use effect, so after each use, be sure to choose the correct cleaning method to clean, dry and then use the next time.

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.
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.
