Importance of Whiteness Control of Aluminum Hydroxide Flame Retardant
Many people in the purchase of aluminum hydroxide flame retardants will find that the whiteness of the product is different, some high whiteness, and some low whiteness, thinking that this is only a normal phenomenon of production effect, but it is not the case. Whiteness in a large way can show the quality of the flame retardant products,
Many people are buying.aluminum hydroxideFlame retardants will find that the whiteness of the product is different, some high whiteness, and some low whiteness, thinking that this is only a normal phenomenon of production effect, but it is not the case. Whiteness can show the quality of the flame retardant product in a large way, so it is very important to control the whiteness of the flame retardant. This is from two aspects:
On the one hand, aluminum hydroxide itself is a high-white powder object, and the whiteness of the processed aluminum hydroxide micropowder is more white. In order to reduce the production cost, some manufacturers use some low-end raw materials to reduce the whiteness of aluminum hydroxide flame retardant, but the quality is not so high. Therefore, controlling the whiteness of aluminum hydroxide flame retardant is an important indicator of the quality of the test period.
On the other hand, some flame retardants do not have too large requirements for aluminum hydroxide powder, and white and gray have no requirements for finished products. However, the use of aluminum hydroxide powder with too low whiteness will cause low content and unstable flame retardant coefficient. There are also some products that have very high requirements on whiteness. For example, the finished product is clean white, and his requirements on the whiteness of aluminum hydroxide flame retardant are very high. The requirements are not only good flame retardant effect, but also good whiteness and transparency. The products are beautiful, beautiful and well sold.
Therefore, the higher the whiteness of the aluminum hydroxide flame retardant, the better the product quality of the flame retardant, the better the use effect, on the contrary, the worse the quality, the worse the use effect. Therefore, whether it is the production and processing of the flame retardant or the purchase and use, we must pay more attention to the conditions of its whiteness.

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.
