Analysis of the Preventive Effect of Aluminum Hydroxide on Cable Fire
With the rapid development of social economy, science and technology, the continuous improvement of people's material and cultural level, high-rise buildings, underground engineering, large space buildings, power communication departments, large enterprises continue to appear, its internal wire and cable applications are more, in order to prevent cable fire
With the rapid development of social economy, science and technology, the continuous improvement of people's material and cultural level, high-rise buildings, underground engineering, large space buildings, power communication departments, large enterprises continue to appear, its internal wire and cable applications are more, in order to prevent the occurrence and development of cable fires, in order to reduce the economic losses causedaluminum hydroxideAs the flame retardant protection of cable, fire retardant coating is of great significance to prevent the initial fire and slow down the spread of fire, protect the safety of the country and people's lives and property, and promote the cause of fire control.
As a special coating, cable fire retardant coating is composed of two parts: base material and flame retardant additive (aluminum hydroxide). In addition to the decorative effect of ordinary coating and the physical protection of cable substrate, it also needs to have the special function of flame retardant and refractory.
After aluminum hydroxide flame retardant materials added to the fire performance of fire retardant coatings, smoke production, corrosion and other experiments to draw the following conclusions:
1. Aluminum hydroxide not only has a good flame retardant effect with a small amount, but also greatly improves the fire resistance and physical and chemical properties of the cable fire retardant coating, while reducing the cost.
2. When adding aluminum hydroxide flame retardant, it has obvious smoke elimination effect on the cable fire retardant coating, which can make the fire retardant coating not only produce smoke and toxic gas when burning, but also have good flame retardant and heat insulation effect.
3. The technical route of adding aluminum hydroxide flame retardant is adopted in the cable fire retardant coating, so that when the cable fire retardant coating is obtained, the coating expands and foams well and densely, forming a dense and uniform fire insulation layer to provide effective fire protection for the cable. However, when the amount of aluminum hydroxide flame retardant is 7%, the cable fire retardant coating has good fire resistance, good physical and chemical properties and clothing resistance.

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.
