Product details :
1.Ammonium aluminum sulfate is a kind of inorganic substances, chemical formula NH4Al (SO4) 2, is a colorless, transparent crystals or white powder. Slightly soluble in water, dilute acid and glycerin, acidic aqueous solution, insoluble in alcohol. Often in form containing 12 water of crystallization.
2.Properties:
colorless vitreous surface crystallization to eight white granular or powder, odorless, slightly sweet taste, has a strong convergence.
Purpose:
baking powder processing, Fried foods, jellyfish flooded stains, vermicelli processing, crisp, color for fruits and vegetables, water purification environmental protection, disinfection, rubber processing, leather, washing powder processing, feed processing, the production of pencils.
Features:
high whiteness, high fineness, high content, long time not agglomeration, provides convenience to users and processing.
Chemical properties:
this product compared with other aluminum salt is not easy to hydrolysis (truth is similar to Moore salt), can be used as a benchmark of aluminum reagent.
3.Chemical properties:
Easily soluble in water, aluminum sulfate in pure sulfuric acid insoluble (only co-exist), in sulfuric acid solution with sulfuric acid dissolved in water, so the solubility of aluminium sulfate in sulfuric acid is the aluminium sulfate in water solubility.
Room temperature precipitation containing 18 molecular crystal water, to 18 water aluminum sulfate, aluminum sulfate on industrial production for 18 more water. Inclusive of our 51.3% anhydrous aluminum sulfate, even if the 100 ºC will not autolyzed (crystallization water soluble in itself).
Not easy to weathering and lose crystal water, stable, heating water, high temperature will be broken down into aluminum oxide and oxide. Heated to 770 ºC is decomposed into alumina, sulfur trioxide,and water vapor. Soluble in water, acid and alkali, insoluble in ethanol. Acidic aqueous solution. Generate aluminum hydroxide hydrolysis. Long time boiling can be generated alkali type aluminum sulfate solution. Industrial products for gray flake, granular or massive, because it contains low iron salt and light green, and due to the low iron salts was oxidized surface yellowing. Coarse product is gray fine crystal structure of the porous material.
4.A good nitrogen (commonly known as ammonium sulphate), suitable for general soil and crop, can make the branches and leaves growth, improve fruit quality and yield, enhance crops on disaster resistance ability, as a basic fertilizer, fertilizer and seed manure, but the long-term use can lead to soil harden. Has double decomposition reaction with salt to produce ammonium chloride and ammonium aluminum sulfate effect generated alum, manufacturing refractory materials with boric acid and so on. Join the plating solution can increase the conductivity. Food caramel catalyst, in the production of yeast cultivation nitrogen source of yeast, to dye and acid dyes leather dust remover. In addition, also used in beer brewing, chemical reagent and battery production, etc. Another important role is to mine rare earths, extraction with ammonium sulfate as raw material, adopts the ion exchange form of rare earth elements in the ore exchange, simple to collect leaching liquid filtration separation after dried into rare earth ore, per 1 ton of rare earth ore mining production need about 5 tons of ammonium sulfate.
