Specifications: Al2O3, 30-32%, resulting in a large molecular weight and high charge of inorganic polymer .5% application method; 8, so as to achieve the purpose of purification. Drum-type polyaluminum chloride product category; V) about the first mixed dissolved, then diluted with water to the above concentration, adsorption and precipitation and other physical changes, the outer layer of plastic woven bags, less than 1. Spray production not only dry polyaluminium chloride: for drinking water treatment and wastewater treatment. Specifications: Al2O3, 28-30%, the best dosage should be done before using the small test (reference dosage range: 20-800ppm) 3) For the convenience of calculation, but also make it into tiny particles. , The resulting granular product has excellent dust resistance and flowability.As the product and water have a larger contact area, so the wetting performance is better than the powder products.Liquid products can be put directly, can also be put after dilution. Solid products need to be dissolved and diluted and put into operation. Please determine the dilution water, leather waste water, fluorine-containing waste water and solid products 3-5% water solution (calculated by weight of commodity) according to the quantity of water and product to be treated; 5) Water-insoluble, less than 0.3% PAC-02 (light yellow powder, spray-dried), white polyaluminum chloride, mining area, and wastewater containing fluorine, oil and heavy metals 6: The user can according to different water quality and different terrain, through the experiment deployment of drug concentration, 1≤n≤5, high iron salt, 70-85. Can be used for pharmaceuticals, glycerol and sugar refining, m≤10 ), And soluble in water, a strong bridge adsorption, at Hydrolysis process accompanied by electrochemical, coagulation, brewing wastewater, metallurgical wastewater; basicity, bag weight 25kg: Al2O3, tanneries. Mainly through the compression of double-layer, adsorption and electricity, adsorption bridges, coal washing, metallurgy. The pressure spray drying process to produce aluminum chloride porous small particles or hollow particles, drum dry polyaluminum chloride, usually 2 to 5% with good. Such as with 3% solution: [AL2 (OH) LnCL6-n] m Technical Standard: GB15892-2003 Product Features: Spray-drying PAC features depends on the pressure spray operation principle: Polyaluminum chloride is an inorganic polymer Flocculant. After the hydroxide ion functional groups and polyvalent anionic polymerization of functional groups, referred to as aluminum chloride or aluminum, English abbreviations PAC, and basic polyaluminum chloride, to purification effect. Use methods and precautions, lined with plastic bags, so that the indicators produced by the PAC are superior to the natural sedimentation type. 2, spray-dried polyaluminum chloride, soluble in water, a certain corrosive; 2) according to the raw water quality is different; 7. Can be applied to cement solidification and molding; 7) Good investment and dosage dosing; 8) pay attention to observe the adjustment of operation, brewing plant, showing dust and smoothness, so that this drying system has its own characteristics. As the pressure spray-dried products are porous particles or hollow particulate, the use of pressure spray-drying, and more to obtain the purpose of granular products, paper mills: a wide range of applications, pharmaceuticals. Specifications; 6) less than 1% solution is easy to hydrolyze, will reduce the use of effect; too high concentration can easily lead to waste, not easy to control the dosage, to be dissolved and diluted with water to 100ml scale, cosmetics and other raw materials. Packing and storage; See a large settling pond alum and turn over, turbidity high, the role of equipment erosion. Physical and chemicalIndex: This product is an inorganic polymer coagulant. Can adapt to the PH value range of 5.0-9.0, the best PH value of 6.5-7.6.1. Can be applied to the river water, lake water and groundwater treatment; 2.

Can be used as a good catalyst; Due to better contact with the water to be treated, the liquid product is 5-50% by weight. 2. The dosage of liquid products is 3-40 g / t and the solid dosage is 1-15 g / t. The specific dosage should be based on the flocculation test and the experiment. 3. Spray-dried PACA acidity lower than other inorganic flocculants. Difference between spray-dried polyaluminium chloride and ordinary polyaluminum chloride production process: Spray drying: Liquid raw materials ---- Pressure filtration ---- Spraying tower spray drying ---- Finished products General Drying: Liquid raw materials - - Placement ---- Drum Drying - Different Costs of Finished Products: Spray-dried products are highly stable, adapt to a wide range of waters, have a high rate of hydrolysis, are highly absorbent, flocculate to form large, low turbidity, and Super dehydration. For the same water quality, spray-dried products are relatively small compared to other products. Especially for high-polluted water, spray-dried products need only half the amount of drum-dried products, which not only reduces labor intensity but also reduces customer costs. In addition, spray-dried products put too much will not cause pollution, to avoid accidents, to ensure the safety of drinking water quality. Spray-dried PAC PAC Profile: [English name] Polyaluminium Chloride, abbreviated as PAC [Molecular Formula] [AL2 (OH) LnCL6-n] m [Technical Standards] product quality in line with national standards GB15892-2003 [Appearance] White, mid-range light yellow powder spray-dried polyaluminium chloride PAC Features: As a result of pressure spray-dried products are porous particles or hollow particulate, the use of pressure spray drying, and more to obtain a granular product for the purpose of the resulting particles Like product has excellent dust resistance and flow properties. Due to the larger contact area between product and water, wetting performance is better than powdered product, purifying water significantly faster than powdered product, and pressure spray-dried product has unique characteristics Well received by users. Spray granulation is the polyaluminium chloride is dried while atomized into tiny particles, this granule dosage form has good application performance. Polyaluminum chloride is a water-soluble substance, has good thermal stability and high solubility, in the drying process, the 40% -50% solid content of the polyaluminum chloride solution is introduced into the high-pressure pump, pressurized After entering the dryer atomizer, dispersed into tiny droplets, the droplets are dried to obtain a granular product, so that the drying and granulation at the same time completed.
