Refractory material
Refractory binder
Increase the bonding of refractory material composition It is one kind of refractory binder. It is a kind of aluminum hydroxide sol made from aluminum-containing material or aluminum metal which subject to several chemical/physical treatment steps such as hydrochloric acid dissolution, hydrolysis, and polymerization. Poly aluminium chloride can be taken as the intermediate of the hydrolysis process of AlCl3 into Al(OH)3 and therefore the hydrolysis solution is acidic. Poly aluminium chloride is also known as hydroxy aluminum or basic aluminum chloride with the chemical formula being [Al2 (OH) nCl6-n] m, wherein if the n is close to or equal to 6, it can be called as alumina sol.
Applying poly aluminium chloride as a binding agent of loose refractory will not affect its refractoriness. The Al2O3 generated during the dehydration and decomposition of poly aluminium chloride during the heating process is a kind of active alumina oxide with high-degree of dispersion which can facilitate the sintering, and thus being suitable for being used as the refractory binder.
Poly aluminium chloride can be used for non-firing or fired to generate refractory products, fire-resistant plastic, and the binding agent of ramming and casting. When being used as the binding agent of monolithic refractory, it has certain requirement on both the alkalinity and density with poly aluminium chloride with either too low or too high bond strength not good.
In general, poly aluminium chloride with alkalized degree being within 46% to 72% and the density being within 1.17~1.23kg/m3 has a good binding strength. When used as the binding agent of refractory casting, it can be used for synthesizing Magnesium aluminium spinel, electronic melting MgO and as the coagulation accelerator of cement. But when applying the poly aluminium chloride as unshaped refractory binder, because of its acidic solution (pH <5), it will have reaction with iron and iron-containing compounds contained in the refractory to release hydrogen and cause swelling of the material. Therefore, the preparation technology should contain aging step in order to avoid the swelling and further cracking of good molded product or lining.
It can be used for the purification process of drinking water as well as various kinds of industrial waste water.
As flocculants, it is mainly used for purifying drinking water and the treatment of special water such as removal of iron, fluorine, cadmium, radioactive contamination as well as floating oil. It can also be used for the treatment of industrial wastewater such as dyeing wastewater. Moreover, it can also be used for precision casting, pharmaceutical, paper, and leathering. In antiperspirants.

Production method
Boiling pyrolysis method: put the crystalline aluminum chloride for boiling and pyrolysis at 170 °C; the generated hydrogen chloride is absorbed by water to prepare 20% hydrochloric acid for recycling. Further add water to have a then added water for aging and polymerization at 60 ℃; Then further go through solidification, dryness, crush to obtain the solid finished product of poly aluminium chloride.
Boiling pyrolysis method: put the aluminum ash (mainly composed of alumina and metal aluminum) into the reactor pre-supplied with washing water at a certain ratio, stir and slowly add hydrochloric acid for condensation reaction with curing and polymerization to a pH of 4.2 to 4.5 and the relative density of the solution being 1.2. Conduct sedimentation to obtain a liquid poly aluminum chloride. The liquid product was subject to dilution and filtering, concentration by evaporation, drying to obtain the solid poly aluminum chloride products.
