Compared to ordinary paintings, the safety factor of aluminum powder is particularly high. Aluminum powder cannot be ignited, so it would not worry about combustion occurs in the transport process.

But in order to be more secure,Introduction of aerated aluminum paste Articles it has been developed aerated aluminum paste. Aerated aluminum paste was very light, uneasy to smash, non-flammable, because there are none of any combustible materials in aluminum powder. Aerated aluminum paste has a variety of excellent features and craftsmanship, particularly has a major role in the construction industry.

 

Aerated aluminum paste is a kind of building materials, in the production process, aluminum powder reacts with silica, quick lime, make the produced concrete formed many structures inside. Aluminum powder in the aluminum paste will react with alkaline chemicals in concrete slurry, produce bubbles and release oxygen. This chemical reaction will swell concrete slurry and form a lot of the porous structure, at this time, the concrete inside structure like bread, pores were evenly distributed in the concrete. Closed pores in concrete has a strong bondacust capacity, 10mm of the wall will be able to absorb 40 db of noise, has good sound insulation effect. The residential building construction is often used aerated aluminum paste to soundproof.

 

Add aluminum pastes in the production process to produce very light aerated concrete blocks, the weight is only 40% of the ordinary concrete bricks. Although it's very light, but the seismic capacity is very strong, its overall performance is good, has a small inertia, good seismic capacity. Because of the concrete added aerated aluminum paste, the produced concrete tiles are made up of many independent small pores, make these pores water absorption increased, almost five times of the ordinary clay brick (the same size, the same time), commonly used in the bathroom wall, after treatment can be directly tiling. Because of the pores and micropores in aerated concrete blocks have good thermal insulation properties, can be used for external wall insulation, it was heat insulation in summer, thermal insulation in winter, can be equivalent to a 49cm thick solid brick wall.

 

Aerated aluminum paste is easier to dissolve in water, and gasing fully while use, very conveniently. However, there are many things need to attention while using aerated aluminum paste. Although these powder nature coating has much higher security than other coatings while use, but there are still some potential dangers. Especially flammable powder combined with air, it will produce a series of changes, eventually become a kind of explosive mixtures. Metal powder supplier advised that you can avoid this problem, as long as take some measures while using. Moreover, in order to ensure the construction safe, the concentration of the powder cannot exceed the requirements. If exceed required, and the oxygen content is plentiful in the environment, then, we must prevent the construction site appearing sparks, or it will cause an explosion.

 

Therefore, while utilizing the aerated aluminum paste, as long as the amount of powder does not exceed the requirements, it will not explode. When spraying, it should be prevent aerated aluminum paste appearing aluminum powder isolated or too concentrated. Moreover, the equipments that the staff used must be finished the grounded processes, the lowest limit to control the indoor content of aluminum powder. And the exhaust system which in accordance with the requirements should avoid open flames, or other sparks produced in any case.
