What is the aluminum hydroxide powder like? What are its uses?
The anodic effect of aluminum hydroxide powder is a parameter that reflects its performance changes, and many people may not be familiar with it. It's ok. Let's take a closer look at this concept. The anode effect is a unique phenomenon in molten salt electrolysis, and the production performance of aluminum hydroxide powder is still obvious. If the anode effect occurs in production, the voltage of the electrolyzer will rise very quickly, to 20 ~ 50 V, or even higher. It will have a great impact on the entire aluminum hydroxide micropowder electrolysis series, reducing current efficiency will affect electrolysis technical indicators, reduce product output and quality, and affect overall power supply. There are two ways to deal with it: use the effect bar to extinguish,

The anode effect is a unique phenomenon in molten salt electrolysis, and the production performance of aluminum hydroxide powder is still obvious. If the anode effect occurs in production, the voltage of the electrolyzer will rise very quickly, to 20 ~ 50 V, or even higher. It will have a great impact on the entire aluminum hydroxide micropowder electrolysis series, reducing current efficiency will affect electrolysis technical indicators, reduce product output and quality, and affect overall power supply. There are two treatment methods: use the effect bar to extinguish, or reduce the anode, increase the amount of aluminum hydroxide powder, so as to extinguish the anode effect.
The anode effect occurs because as the electrolysis progresses, the oxygen ions in the micropowder electrolyte gradually decrease. When a certain level is reached, fluorine precipitates and reacts with anode carbon to form fluorinated carbon. When the fluorinated carbon is decomposed, fine carbon particles are precipitated. These carbon particles adhere to the surface of the anode to prevent the electrolyte from contacting the anode, so that the aluminum hydroxide powder cannot wet the anode well. When new fine powder is added, oxygen precipitates on the anode, and the oxygen gradually reacts with the carbon powder.
Alumina powder is used as a raw material for high-alumina refractory materials, ceramic devices, automobile spark plugs, polishing and grinding products, etc. It is the basic material for the production of high-alumina amorphous refractories, and it is also a high-quality filler to improve the performance of refractory products. Its use is mainly reflected in the following aspects.
1. Various aluminum hydroxide powder raw materials, plastics, rubber and other flammable materials flame retardant additives, papermaking, surface pigments, coatings, toothpaste substrates, catalyst carriers, water purifiers, fluoride salts, desiccants, Various molecular sieves, pharmaceutical industry, artificial agate, glass mosaic, quick-setting filler for building materials, etc.
2. Activated aluminum hydroxide powder can improve the combination and processing performance of aluminum hydroxide powder and resin, so that it has both flame retardant and filling properties. Therefore, adding this product to advanced composite materials such as plastics and rubber not only makes the product flame-retardant and smoke-suppressing, but also enhances its anti-leakage, arc-resistant, and wear-resistant properties. It can be used for low-density polyethylene cable material for power, wire and cable insulation layer, sheath layer, rubber, heat insulation material, conveyor belt, etc.
Because of the good characteristics of alumina powder, it is widely used in various fields. If you want to use it better, you need to learn more about it to prevent unnecessary troubles, waste of costs, and unsatisfactory results.

good morning! Today I will introduce the performance of low-smoke halogen-free aluminum hydroxide
In order to improve the compatibility and adhesion between the polyethylene matrix and the inorganic flame-retardant interface, low-smoke halogen-free aluminum hydroxide is used to fill the composite cable material with maleic acid grafted EVA and aluminum hydroxide, magnesium hydroxide and other halogen-free flame-retardant fillers . Low-smoke halogen-free aluminum hydroxide improves the dispersion and compatibility of magnesium hydroxide and aluminum hydroxide, maximizes the flame retardancy of cable materials, reduces smoke index, smoke volume, calorific value and carbon oxide production, and improves The oxygen index improves the dripping performance and significantly improves the mechanical and thermal properties of the material.

Adding a small amount of low-smoke halogen-free aluminum hydroxide to composite materials can significantly improve the mechanical properties, tensile strength and elongation, heat resistance and flame retardancy of composite materials. Coupling agent: used for halogen-free flame retardant materials such as magnesium hydroxide and aluminum hydroxide to improve the interface compatibility and adhesion between the polyolefin lamp matrix and the inorganic flame retardant. When the added amount of composite material is 8%-10%. The mechanical properties and thermal resistance of the low-smoke halogen-free aluminum hydroxide composite material have been greatly improved. Compared with silane, titanate, aluminate, and phosphate coupling agents, the mechanical properties of polyethylene cable materials have been greatly improved. Dispersion accelerator: used for light-color masterbatch, flame-retardant masterbatch, degradation masterbatch, etc., because it is combined with pigments and dyes.
To
The low-smoke halogen-free aluminum hydroxide flame retardant has a strong interaction, which can promote the dispersion of pigments, dyes and flame retardants in the polyethylene lamp resin. Tackifier: high polarity, high reactivity. A small amount of additives can significantly improve the coating, adhesion and compatibility of the material. The development of new varieties of low-smoke halogen-free aluminum hydroxide mainly includes: increasing the surface area of aluminum hydroxide particles, that is, miniaturization and ultra-fineness, and reducing the partial pressure of water v***r on the surface of the particles.
Low-smoke halogen-free aluminum hydroxide can improve the heat resistance of aluminum hydroxide and significantly improve the mechanical properties and flame-retardant effect of the material. The experimental results show that when the average particle size of aluminum hydroxide is 5 μm, the oxygen index is 28, and the particle size is less than 1 J μm, when aluminum hydroxide reacts with substances with higher thermal decomposition temperature.
It is possible to synthesize new products with a thermal decomposition temperature between the two. For example, the eutectic of aluminum hydroxide and sodium carbonate decomposes at 300-350°C, releasing water and carbon dioxide, which has a strong inhibitory effect on hydrogen and smoke. It is an excellent flame retardant for PVC and polyolefin.
The content of ionic insolubles in aluminum hydroxide, especially uranium oxide, is reduced to less than 0.2% by mass. Surface treatment commonly used silane coupling agent, titanate coupling agent and stearic acid (salt) to modify the surface of aluminum hydroxide. This aspect has just started in China, and a new type of special functional aluminum hydroxide surface modifier and a new variety of inorganic synergist have been developed abroad.
A small amount of flame-retardant synergist of low-smoke halogen-free aluminum hydroxide can significantly improve the performance of aluminum hydroxide filler, such as inhibiting dripping and improving mechanical properties. It has a variety of inorganic flame retardant synergists with aluminum hydroxide, including metal oxides and zinc borate, phosphorus compounds (red phosphorus, phosphate), silicon compounds, metal nitrates (copper nitrate), polyphosphates, etc. The second is a new variety of magnesium hydroxide.
Low-smoke halogen-free aluminum hydroxide mainly includes: Many people believe that magnesium hydroxide can replace aluminum hydroxide. However, due to the strong polarity of the internal physical crystal water and magnesium hydroxide, the compatibility with polyolefin lamps is poor. Although the mechanical properties of the coupling agent have been improved, it is not obvious. It is not yet mature to fill a large amount of magnesium hydroxide in polyethylene lamps.
Low-smoke halogen-free aluminum hydroxide When w[Mg(OH)2]:w[AI(OH)3]=1:1, PE has the best synergistic effect. Coating magnesium hydroxide with special fatty acids can improve the rheological and physical properties of the filled polymer. When the filling amount is 50-60%, the filling fluidity is still good. In addition, it is also useful to prepare finemagsn by controlling the growth of micron-sized crystals.

Morning！Today, I will introduce the application of aluminum hydroxide flame retardant。
Because of its characteristics, aluminum hydroxide flame retardants have corresponding applications in different materials. Now let the aluminum hydroxide manufacturer take you to understand its application!
In recent years, with the continuous advancement of science and technology, polymer materials have been used in daily life. However, due to their flammability and high smoking characteristics, they are likely to cause fires and other dangers. Therefore, it is necessary to perform flame retardant treatment on polymer materials. ongoing. Among the inorganic flame retardants, aluminum hydroxide has three major functions: flame retardant, smoke suppression, and filling. It is chemically inert, non-toxic, and does not produce secondary pollution, so it is known as "no pollution Burning agent". Because of its characteristics, aluminum hydroxide flame retardants have corresponding applications in different materials. Now let the aluminum hydroxide manufacturer take you to understand its application!

When using unsaturated polyester to make various electrical switches, adding aluminum hydroxide can make the product have flame retardancy, smoke suppression and arc resistance. Because high white aluminum hydroxide has a certain crystalline form, in recent years, polyester resin and aluminum hydroxide are commonly used to make a new type of decorative material-"artificial agate".
2. Epoxy resin
In epoxy resins, the role of aluminum hydroxide is more obvious, which can greatly increase the oxygen index. Such epoxy resins can be used for sealing materials, castings, epoxy glass fiber sheets, etc. The epoxy resin filled with aluminum hydroxide reflects this huge role in the production of transformers, insulating equipment, switchgear and so on.
3. Thermoplastics
Aluminum hydroxide is also used as a flame retardant in polyvinyl chloride, because aluminum hydroxide can replace calcium carbonate and be incorporated into polyvinyl chloride. In order to achieve high standards of flame retardancy, we can use aluminum hydroxide and phosphate ester plasticizers together, and we can also use aluminum hydroxide and zinc borate together. These are often used in PVC wire and cable materials. The addition of aluminum hydroxide to plastic products such as polyethylene and polypropylene is not only flame-retardant, but also widely used in electrical conduits and equipment jackets through new surface treatment technologies in recent years.
