introduction | aluminum lactate is a yellow or white crystal or powder, free of impurities, soluble in water, pH 5-5.5, and lactic acid content above 45%. Combustible, burning will produce stimulating smoke. |
Application | Aluminum lactate has the characteristics of good coagulability, good spreading, good unity, and strong air permeability under alkaline conditions. It can ensure the operating performance of the material when used as a refractory material formula, and then accompanied by the gelation of aluminum, the strength of the material increases and the aeration rate increases, special effects such as the increase in the heat transfer rate of the spray feed. |
production method | add stoichiometric amount of aluminum hydroxide powder to the aqueous solution of lactic acid, heat and stir to dissolve most of the aluminum hydroxide. After cooling, filter and evaporate the filtrate to dryness to obtain the product aluminum lactate powder. |
