Safety matters to keep in mind in the use of magnesium hydroxide
Magnesium hydroxide flame retardants are divided into many types. Some flame retardants may have safety problems if they are used incorrectly, such as red phosphorus flame retardants.
Magnesium hydroxideThere are many kinds of flame retardants. Some flame retardants may have safety problems if they are used incorrectly, such as red phosphorus flame retardants. So, how can we do to protect their own security? According to these questions, please be sure to pay attention to the following requirements.
Comprehensive toxicity assessment of flame retardants suspected to be harmful to human health and the environment, and strict control of their production, use and acceptance. Once it is confirmed that it is not suitable for use, production and sales will be stopped. For example, tri (dibromopropyl) phosphate was once a widely used and very effective halogen-free flame retardant, but it was later found to be carcinogenic and has long been banned in many countries. The flame retardants penta-and octaBDE, which have been assessed to be toxic, have also recently been banned.
For the newly developed flame retardant products, their impact on human health, safety and environment has been comprehensively studied and evaluated. Can provide more detailed information on the above aspects to ensure the safety of production and use. On the one hand, people are trying to improve and enhance the safety level of existing flame retardants and flame retardant materials, on the other hand, they are committed to the development of new environmentally friendly flame retardants (such as halogen-free halogen-free flame retardants), and are gradually promoting their use (such as the current global halogen-free flame retardant polypropylene has reached about 20% of the total flame retardant polypropylene). It is believed that the development of new halogen-free flame retardants will ensure the use of flame retardant materials, both to reduce fire hazards and to minimize their impact on the environment.
Choosing to use flame retardant masterbatch is also a good method. The flame retardant is unevenly mixed and the proportion is not accurate. At the same time, it causes workshop pollution, workers' skin allergy and other problems. There are many matters needing attention in use, increasing human and financial resources. The flame retardant masterbatch can avoid the above problems. The flame retardant masterbatch is the same as the raw material. The product form is particles of the same size as the raw material. The mixture is very uniform and dispersed. At the same time, it will not cause dust pollution and skin allergy of workers. Direct mixing and injection molding is convenient to use and cost saving.
When we must use flame retardants, we must pay attention to our own safety problems, so as to prevent them and protect ourselves.

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.
