1. When use solid product, make 5-10% solution first, then dilute to request concentration; during the dissolution, add the water and mix slowly, the diluted solution should be used up in 24 hours to avoid hydrolysis and reduce the effect. The dose quantity of this product is based on water resource haziness and purifies facility, the coagulating sedimentation test is needed to ensure the best dosing quantity.
2. Use the polyethylene plastic barrel to store liquid Poly-aluminium Chloride, the net weight of each barrel is 25kg, 50kg or 200kg. And covered with double cover, fasten the inner cover, screw the outer cover. The liquid Poly-aluminium Chloride can also be transferred by tank vehicle. The solid Poly-aluminium Chloride is packed by double bag, the net weight of each bag is 25kg, inner bag is plastic bag, and outer bag is plastic basket bag. The product should be stored in dry, airy warehouse and avoid drench and breathing

| Inorganic high-molecule polymers |
Poly aluminium chloride is an inorganic high-molecule polymer with some cementitious property. It can be used as the binder of refractory coating, ultra-pure alumina products and refractory concrete material. Poly aluminium chloride is a multivalent, polyhydroxy electrolyte and can be seen as the intermediate product of the hydrolysis of AlCl3 into Al (OH) 3. The colloidal nucleus contains positive charge with the hydrolysis product being acidic. The composition of these products is the mixed system of various kinds of aqueous complexes in certain ratio under certain conditions. Its expression formula is [Al2 (OH) n • Cl6-n] m, wherein n = 1-5, m≤10. Owing to the difference in the preparation and performance, Poly aluminium chloride can also be called as hydroxy aluminum chloride, basic aluminum chloride, and polymeric alumina. The main index of physical and chemical properties includes alkalinity, pH value, Al2O3 content and the relative density. Poly aluminium chloride is rich in raw materials and has low cost without causing decrease of the refractoriness of refractory concrete. It also has strong activity at high temperatures and can be hardened at room temperature when doped with small quantities of accelerators and thus is promising cement material. Figure 1 is a solid ploy aluminium chloride. |
| Coagulant |
Coagulant is a kind of chemical agent which can promote the coagulation and flocculation effect of the colloidal particles in water and accelerate the formation of coarse particles, thus making it be easier to be subject to fast sedimentation or filtration. Coagulants include coagulant, flocculants, and coagulant aid agent. These nouns currently have no strict uniform definition and boundaries. Coagulants and flocculants, and coagulant aid agent are often mixed for application. Commonly used coagulant includes alum, poly aluminium chloride, activated silicic acid, polyacrylamide, magnesium alumina, ferrous sulfate and ferric chloride, etc. The combination between poly aluminium chloride and alum can give the best efficacy. Poly aluminium chloride is a new type of inorganic polymer coagulant with its fundamental difference with the traditional inorganic coagulant being that the traditional inorganic coagulant is crystalline salt with low molecular weight while the structure of poly aluminium chloride consists of multi-shaped multivariate carboxyl complex. Poly aluminium chloride has a rapid flocculation and sedimentation speed, wide applicable range of PH value, and is non-corrosive to plumbing with a very significant water purification effect. It can effectively remove the water color quality SS, COD, BOD, and arsenic, mercury and other heavy metal ions. This product is widely used in drinking water, industrial water and wastewater treatment, it has the following characteristics: 1. The water purified form poly aluminium chloride has a higher quality than the water purified from inorganic coagulant such as ferric chloride and aluminum sulfate. The cost of poly aluminium chloride in purifying water is also relatively low. 2. Both the formation rate of floc unit and the settlement rate are high. It also has a greater processing capability than traditional flocculant such as ferric chloride and aluminum sulfate. 3. It has a stronger adaption capability on the temperature, turbidity and the alkalinity of the water source than traditional flocculant such as ferric chloride and aluminum sulfate. 4. It has a wide adaptation pH range for the source of water with being able to exert coagulation effect from the range of PH5.0-9.0 with the best results occurring at PH6.5-7.5. 5. It has a small corrosion effect and a good operating condition. 6. It has a better solubility than ferric chloride and aluminum sulfate. 7. After the treatment, the residue of aluminum and salt in water is small which facilitates the handling and preparation of ion exchange. The above information is edited by the chemicalbook of Dai Xiongfeng. |
| Performance |
The main physical and chemical properties of the Poly aluminium chloride are demonstrated from alkalized degree, pH value, Al2O3 content and density. Alkalized degree (B) and pH: alkalized degree means the degree of Cl- (in poly aluminium chloride) being substituted by OH-; it is generally represented using the ratio of the hydroxyl group percentage over aluminum, namely, B = [OH] / 3 [Al] × 100%. Many features of the Poly aluminium chloride are closely related to its alkalized degree including the degree of polymerization, pH, storage stability and the cementing property of being used as a cementing agent. But we should note that the alkalized degree only represents a statistical average value from the mixture containing various kinds of poly aluminium chloride with different degrees of polymerization. The pH value of the liquid Poly aluminium was similar with its alkalized degree. However, these two parameters don’t have exactly the same meaning. The alkalized degree indicates the number |
