26% Polyaluminum Chloride
26% polyaluminum chloride product overview:
The 26% polyaluminum chloride series products are referred to as PAC for short, and are also commonly referred to as water purification agent, polyaluminum chloride, polyaluminum or flocculant. It is a water-soluble inorganic high molecular polymer between AlCl3 and Al (OH) 3. The general chemical formula is [Al2 (OH) ncl6 NLM], where M represents the degree of polymerization and N represents the neutrality of PAC. This product is refined by using excellent calcium aluminate powder, hydrochloric acid and other raw materials after chemical reaction, Yuzhou PAC pharmaceutical series products are characterized by high polymerization degree, large molecular weight, fast flocculation and obvious water purification effect. The colors are divided into reddish brown, light yellow and white powdery solid.
26% polyaluminum chloride has strong bridging and adsorption properties. During the hydrolysis process, many physicochemical processes such as condensation, adsorption and precipitation of polyhydroxy groups occur.
26% polyaluminum chloride product specification:
Appearance: Tan
Alumina content%: 26
Basicity%: 88
Water insoluble content%: < 1
Applications fields of 26% polyaluminum chloride:
The essential difference between PAC agent and traditional inorganic coagulant is that the traditional inorganic coagulant is a low molecular crystalline salt, while the structure of PAC is composed of complex with variable morphology. It has fast flocculation and sedimentation speed, wide application range, no corrosion to water treatment equipment, obvious water purification effect, and can effectively support the color SS, COD, BOD, arsenic, mercury and other heavy metal ions in water. This product is used in drinking water It is widely used in industrial water and sewage treatment.
Advantages of 26% polyaluminum chloride:
Due to the advantages of spray drying, such as good stability, wide water area, fast hydrolysis speed, strong adsorption capacity, large alum formation, fast quality density and sedimentation, low turbidity of outlet water, good dehydration performance, etc., the dosage of spray type polyaluminum chloride is reduced under the same water quality, especially when the water quality is poor, the dosage of spray drying products can be reduced by half compared with roller drying polyaluminum chloride, It not only reduces the labor intensity of workers, but also reduces the water production cost of users. Polyaluminum chloride, referred to as polyaluminum chloride, or PAC. It is formed by reaction polymerization of raw materials with high degree of use using the most advanced production process at present. All the quality indicators have reached or even exceeded the requirements of the national standard gb15892-2009. Polyaluminum chloride is processed by spray drying process, so it can also be called spray drying polyaluminum chloride. Characteristics of polyaluminum chloride product: it has the characteristics of fine powder, uniform particle, easy to dissolve in water, good flocculation effect, stable purification, small dosage and low cost. Suitable for drinking water purification, urban water supply purification and industrial water supply purification; It is applicable to source water of various turbidity, with a wide range of pH, large and fast alum formation and fast sedimentation.
26% polyaluminum chloride product features:
1. Polyaluminum chloride has large molecular structure, strong adsorption capacity, low dosage and low treatment cost.
2. It has good solubility and high activity. The alum formed by coagulation in water is large and settles fast, which is 2-3 times greater than the purification capacity of other inorganic flocculants.
3. It has strong adaptability and is less affected by pH value and temperature of water body. After purification, the raw water reaches the national drinking water standard. The content of cation and anion in the treated water is low, which is conducive to ion exchange treatment and preparation of high-purity water.
4. It is less corrosive and easy to operate, which can improve the labor intensity and working conditions of the dosing process.
5. It can achieve good coagulation effect for raw water with serious pollution or low turbidity, high turbidity and high chroma.
6. When the water temperature is low, it can still maintain a stable coagulation effect, so it is more suitable in northern China.
7. The formation of alum is fast; The particles are large and heavy, the precipitation performance is good, and the dosage is generally lower than that of aluminum sulfate.
8. The suitable pH range is wide, ranging from 5 to 9. When it is added in excess, it will not cause the reverse effect of water turbidity like aluminum sulfate.
9. Its alkalinity is higher than that of other aluminum salts and iron salts, so the corrosive effect of the chemical solution on the equipment is small, and the pH value and alkalinity of the treated water decrease less.
26% polyaluminum chloride packaging and storage:
1. Liquid products can be transported in tank cars or plastic barrels, and can be stored in the pool with a storage period of one year.
2. Solid products are packed in plastic woven bags lined with plastic film bags, with a net weight of 25kg each.
3. Solid products are easy to absorb moisture and deliquesce (after deliquescence, the use effect will not be affected), and should be stored in a ventilated and dry place. The storage period of solid products is one year.
4. This product shall not be mixed with hazardous substances for storage.
