Advantages of Aluminum Hydroxide
Highly efficient flame retardant properties
Aluminum hydroxide is widely used in many fireproof materials and fireproof coatings due to its efficient flame retardant properties. It can reduce the risk of fire and improve the fire safety of buildings and facilities.
Environmentally friendly
As an inorganic compound, aluminum hydroxide degrades quickly in the environment and does not cause long-term negative effects on the natural environment. This makes it widely used in environmental protection and water treatment.
Excellent moisture absorption
Aluminum hydroxide has excellent hygroscopicity, so it is often used in the manufacture of hygroscopic and desiccant agents. This property allows it to remain dry in humid environments and protects other products from moisture and corrosion.
Improved product texture
In the cosmetics and food industries, aluminum hydroxide is used as an emulsifier and acid neutralizer to improve the texture and taste of products and enhance the consumer experience.
Uses of Aluminum Hydroxide
Chemical raw materials
Aluminum hydroxide has many advantages including large-scale production, adequate raw materials, high product purity and good solubility in acid. Therefore, aluminum hydroxide can be used as an important raw material for the preparation of aluminum salts, such as barium aluminate, aluminum sulfate and so on.
Flame retardants
Aluminum hydroxide powder is commonly regarded as an ideal flame retardant filler for plastics, unsaturated polyester, rubber and other organic polymers because of its filling, flame retardant and smoke-eliminating functions and non-toxic property. Flame retardant mechanism of aluminum hydroxide is as follows: when the temperature exceeds 200 ℃, the aluminum hydroxide begin to perform endothermic decomposition and release three crystal water, and its decomposition rate reaches the largest at 250℃.
This reaction is a strong endothermic reaction, thereby inhibiting the polymer temperature rise, reducing its decomposition rate and only producing water vapor, not generating toxic and harmful gases.
Ceramics
Aluminum hydroxide can transform into alumina, which has high thermal chemical stability, thermal strength, creep resistance and dielectric properties and low thermal expansion coefficient. Alumina is an important material for the synthesis of ceramics. In the process of ceramic synthesis, we can control the phase formation of the composite by aluminum hydroxide activation and crystallization process controlling.
Sewage treatment
Aluminum hydroxide exists in water mainly in form of Al(OH)4-, which can precipitate toxic heavy metals in sewage by coprecipitation method to achieve the effect of water purification after further filter. Aluminum hydroxide has a high specific surface area, and can adsorb colloid, suspended solids, dyes and organic substances in sewage on its surface.
Medicine
Aluminum hydroxide can neutralize gastric acid and is non-toxic, for which it is always used as the traditional medicine for the treatment of stomach. The aluminum hydroxide as adjuvant can also improve the immunogenicity of the vaccine, the action mechanism of which is as follows: aluminum hydroxide adsorbs antigen on its surface to allow the antigen slow release so that it can play the role of extending efficacy.
Catalyst carrier
In the preparation of aluminum hydroxide, we can obtain various target products with diffrernt surface area, pore volume, pore structure and crystal structure by controlling the temperature, concentration and pH of the reactants, which can be effectively used as a catalyst carrier for the hydrogenation of unsaturated carbonyl compounds and the preparation of fullerenes and the like.
Paper industry
Aluminum hydroxide has high whiteness, ultrafine particle size as well as complete crystal form, and has a strong compatibility with brightening agent. Aluminum hydroxide, as an additive coating and resin, can effectively improve the whiteness, opacity, smoothness and ink absorption of coated paper.
Properties of Aluminum Hydroxide
Physical properties
- Aluminum hydroxide occurs in the form of a white amorphous powder.
- Aluminum hydroxide has a melting point of around 573K.
- Aluminum hydroxide is insoluble in water but soluble in alkalis and acids.
- Solid aluminum hydroxide has a density of around 2.42g/cm3.
Chemical properties
- Aluminum hydroxide is an amphoteric substance.
- It may function as both an acid and a base.
- Aluminum hydroxide behaves as a Bronsted–Lowry base in acids.
- As a result, it neutralizes the acid-forming salt and water that are the end results.
