But inorder to be more secure, it has been developed aerated aluminum paste. Aeratedaluminum paste was very light, uneasy to smash, non-flammable, because thereare none of any combustible materials in aluminum powder. Aerated aluminumpaste has a variety of excellent features and craftsmanship, particularly has amajor role in the construction industry.Aeratedaluminum paste is a kind of building materials, in the wholesale D301 Steel Rollators With Three 7.5 Wheels production process,aluminum powder reacts with silica, quick lime, make the produced concreteformed many structures inside. Aluminum powder in the aluminum paste will react with alkaline chemicals inconcrete slurry, produce bubbles and release oxygen. This chemical reactionwill swell concrete slurry and form a lot of the porous structure, at thistime, the concrete inside structure like bread, pores were evenly distributedin the concrete.
Closed pores in concrete has a strong bondacust capacity, 10mm of the wall will be able to absorb 40 dbof noise, has good sound insulation effect. The residential buildingconstruction is often used aerated aluminum paste to soundproof.Add aluminumpastes in the production process to produce very light aerated concrete blocks,the weight is only 40% of the ordinary concrete bricks. Although it's verylight, but the seismic capacity is very strong, its overall performance isgood, has a small inertia, good seismic capacity. Because of the concrete addedaerated aluminum paste, the produced concrete tiles are made up of manyindependent small pores, make these pores water absorption increased, almostfive times of the ordinary clay brick (the same size, the same time), commonlyused in the bathroom wall, after treatment can be directly tiling.
However, there are many things need to attention while usingaerated aluminum paste. Although these powder nature coating has much highersecurity than other coatings while use, but there are still some potentialdangers. Especially flammable powder combined with air, it will produce aseries of changes, eventually become a kind of explosive mixtures. Metal powder supplier advised that you can avoid this problem, as long as take somemeasures while using. Moreover, in order to ensure the construction safe, theconcentration of the powder cannot exceed the requirements. If exceed required,and the oxygen content is plentiful in the environment, then, we must preventthe construction site appearing sparks, or it will cause an explosion.Therefore,while utilizing the aerated aluminum paste, as long as the amount of powderdoes not exceed the requirements, it will not explode. When spraying, it shouldbe prevent aerated aluminum paste appearing aluminum powder isolated or tooconcentrated. Moreover, the equipments that the staff used must be finished thegrounded processes, the lowest limit to control the indoor content of aluminumpowder.
