[Products] Industrial PAC, referred to as poly aluminum. Two types of solids and liquids, solids, golden yellow or khaki granular / flake, liquid brown color. The product of the high turbidity of the water purification effect is particularly evident; without alkaline additives or other additives; alum formed fast, easy settlement; adapt dosing range, excessive dosing does not cause side effects, net water safety, less corrosive. [Applications] PAC commonly used in industrial-grade industrial water, industrial waste water, industrial water recycling and urban sewage purification, mainly used in leather, paper, printing and dyeing, metallurgy, coal, oil and other industries. Technical index of the companies involved in PAC national standards GB-T 22627-2008 Index Name GB/T22627-2008 liquid solid alumina (Al2O3 interest in) the mass fraction /% ≥ 6.0 28.0 Basicity /% 30 -95 Density (20 ℃) ??/ (g/cm3) ≥ 1.10 - insoluble mass fraction /% ≤ 0.5 1.5 pH value (10g / L aqueous solution) 3.5-5.0 iron (Fe) mass fraction /% ≤ 2.0 5.0 Arsenic (As) mass fraction /% ≤ 0.0005 0.0015 Lead (Pb) mass fraction /% ≤ 0.002 0.006 Note: The products listed in the table insoluble liquid, iron, arsenic and lead the mass fraction refer Al2O3 10% of product content When the Al2O3 content is not equal to 10%, the actual content should be folded into Al2O310% Product ratio to calculate the corresponding quality scores. Usage Measures 1. Put the amount is generally: solid product 1-15kg / thousand tons of water, the liquid 3-40kg / thousand tons of water, the specific amount invested by the user to determine the amount of the actual experiment. 2 different situations according to the raw water prior to use small test can do first obtain the optimal dose. For ease of calculation, a small weight ratio configuration test solution (W / W), generally with 2-5% as well. As with 3% solution: poly aluminum chloride solids 3g, poured into a wash 200ml graduated cylinder, add water about 50ml, to be dissolved with water diluted to 100ml mark, shake well. 3 dosing obtained by small scale best dosage dosing and observe in the operation of adjustments. See, for example less sedimentation tanks alum, I voiced large, the dosage is too small; see, for example alum large settling ponds and on the turn, I turbidity is high, excessive dosing should be adjusted appropriately. [Note] The product is prohibited mixed with other chemicals, transportation and storage, the product should be stored in dry, ventilated, cool place. Effective storage of products: liquid 6 months, solid 12 months. Solid product can still be used when wet.
