Spray light yellow 30% PAC
[molecular formula][AL2 (OH) LnCL6-n]m
Standard: the product quality in line with national GB15892-2009 standard
Appearance: upscale white and middle light yellow powder
Characteristics of spray-drying
Pressure type spray drying characteristics of polyaluminum chloride is mainly determined by pressure atomizer works so that the drying system has its own characteristics.
Due to the pressure type spray drying products are grainy or porous hollow particle-like, pressure type spray drying, how to get granular products for the purpose of income dust properties and flow of granular products have excellent performance.
Due to the product and have a greater contact area between the water, wetting performance better than the powder, purified water speed significantly higher than powder products, pressure type spray drying of the product has unique characteristics, so deeply user high praise.
Spray granulation is the PAC was dry at the same time atomized into tiny particles, the particles form a good application performance.
Poly aluminium chloride is water-soluble substances, has good thermal stability and High solubility, drying, 40%-50% of solid content of poly-aluminium chloride solution introduced in the high pressure pump, through pressure atomizer for atomizing of backward into the dryer, dispersed into tiny droplets, droplets are granular products after drying, drying and pelletizing complete.
Product features
1) a great deal with a positive charge, nuclear morphology and stability of hydroxy aluminum complexes, can effectively promote flocculation, sizing.
2) white very low iron content, can meet the needs of manufacturing high quality paper
3)of hydrolysis of poly-aluminium chloride is aluminum chloride, hydrolyzed comparatively less, smaller decline than the sulfate pulp pH values.
4)use polymeric aluminum chloride sizing, sizing of retention and drainage AIDS has improved significantly.
5) apart from breaking length paper performance, other indicators are improving in varying degrees.
Spray-drying poly-aluminium chloride and difference between drum drying polymeric aluminum chloride production process:
Spray drying:
Liquid raw materials spray spray drying Tower in pressure filter products
Drum drying
Drum drying natural settlement of liquid raw materials production
Poly-aluminium chloride, is a multi-hydroxy, multicore inorganic polymer complex body of cationic flocculant, of low poly-aluminium chloride on corrosion of pipeline equipment;
Poly-aluminium chloride is widely used for drinking water, industrial water and wastewater treatment.
Specification and use: should be used for water purification, wastewater and sludge treatment, industrial and chemical waste water treatment;
Cement setting refining, casting molding, raw materials for cosmetics, pharmaceuticals, paper size, and so on.
To use: 1. use direct dosing the amount of product to be processed in the water, and strong mixing with the water mix evenly.
2. the specific dosage as the water source may be, beaker used for coagulation tests, determine the optimal dosage
3. this product to avoid moisture, moisture can still use, in effect unchanged.
Areas of application of poly-aluminium chloride:
1, water: domestic water, industrial water;
2, urban wastewater treatment;
3, sewage, sludge, industrial waste water treatment and sewage in the mass recycling of slag;
4, for certain difficult industrial sewage treatment, with PAC as the mother, mixed with other chemicals to mix composite PAC, wastewater can get the surprise effect.
Performance characteristics of poly-aluminium chloride:
1, molecular structure of polyaluminum chloride, strong adsorption capacity, the amount of small, low cost.
2, good solubility, high activity in condensed form of alum in the water, faster settlement, 2-3 times stronger than other inorganic flocculant for purification capacity.
3, strong adaptability, under the influence of PH value and temperature of water body small, introducing water water purification up to the national standard, the treated water quality Chung Yang, low content of anion, and ion exchange process and the preparation of high purity water
4, corrosive small, easy to operate, can improve the dosing process of labor and working conditions
Function and use
1, the product can be widely used for drinking water, industrial water and wastewater purification.
2, quick response, less drug consumption. Alum, quick settlement, the filter is good, increase equipment utilization, low cost of water.
3, adding excess does not produce side effects, easy operation and management; No corrosive effect on the water equipment and piping.
Scope
1, the adapt water pH value range for 5-10, but the best range of pH values of 6-8;
Adaptable 2, dealing with water, suitable for all kinds of water treatment, and have solve other chemicals not deal with low turbidity and low temperature water (4 ° c) and slow, ineffective response challenges.
Using methods and points for attention
1, according to the different raw water conditions, can do small trial first before seeking the best dose. For ease of calculation, configuration test solution by weight (w/w), with 2~5% distribution as well. With 3% solution: solid 3G of poly aluminum chloride, wash 200ml sung in the graduated cylinder, jiaqingshuiyue 50ml, Until dissolved and then dilute with water to the 100ml scale, shake the can.
2, poly aluminum chloride for the production of solid: 1:15 clear water =1:9 to weight ratio (liquid product is 1:2 per cent) mix dissolve. Hydrolysis of aluminum oxide content of less than 1% solution, will reduce effectiveness of high concentration is too easy addition of uniform
3, dosing scale seeking the best dosing the amount of dosing, and look at adjusting in the running. See fewer sedimentation tanks alum, and dark, the dosing volume is too small; As seen on sedimentation alum and, cloud high, the dose should be adjusted.
4, dosing facilities should be corrosion. This product applies to all water treatment facilities.
Installation, transport and storage requirements
1, bags, light relief, so as to avoid damage.
2, must not be toxic and hazardous materials were transported a total of storage.
3, should be stored in a cool dry place.
4 effective, solid product storage period of one year; Liquid products storage period of six months.
5, solid product packaging bag lined with polyethylene film, double coat woven bag packaging, bag zhakou (or heat, the bag should be firmly sealed) 25 kg/bag, Liquid products meet the health requirements, cleaned, sealed by tanks or plastic container shipping.
