1.white powder
2.Al2O3:above 29%
3.High purity and low iron content, is meeting the needs of paper and cosmetics.
PAC(
High-purity)
High-purity PAC (PAC) is a new and highly efficient inorganic polymer coagulant, this product use pure raw materials (aluminum hydroxide, synthetic hydrochloric acid) are made with advanced technology, has a good flocculation effect, its water better than the traditional aluminum and iron salts of sulfuric acid and other common inorganic coagulant and the general Basic aluminum chloride, solid product by spray-drying technology, products for the milky white or light yellow solid, iron content 100PPm less widely used in the water supply and industrial water purification, for paper sizing and re-equipped with production of industrial paper-making additives used in cosmetics production for domestic and international high-purity poly-aluminum chloride product.
1, structural characteristics and flocculation mechanism
PAC (PAC) consists of a series of different degree of polymerization of the inorganic polymer formed, with the best form of distribution. Main components AL13O4OH24 (H2O) 24 (H2O) 127 +, as having the structure of highly charged polymer KEGGIN ring with shape, colloidal and particulate matter in water with a high degree of charge neutralization and bridging functions, and can strongly remove the micro-organic toxins and heavy metals ion, a stable trait.
In water and colloidal particles brought about by the negative charge generated in the moment and the role, so that colloid destabilization, rapid flocculation of colloidal particles, and further bridge generates large and fast settling floc.
2, flocculation characteristics and performance of
Compared with the traditional inorganic coagulant, the product also has the following advantages:
* High purity and low iron content can meet the paper and cosmetics.
* Fast floc formation, settling quickly, large processing capacity than conventional products.
* Back to the body appearance of the product was white, particle uniformity, liquidity is good.
* The solution turbidity is low, and good stability.
* Applies to a wide range of PH value in the 5.0-9.0 can be used within the scope.
* Residual dissolved salts at least conducive to ion-exchange process and manufacture of highly pure water.
* Pairs of turbidity, alkalinity, organic matter content in adaptability.
* The low temperature, low turbidity water to maintain good flocculation.
* The amount of residual free aluminum low, purified water meet the national standard.
* Corrosion is small, easily dissolved powder is better than other similar products.
3, PAC (PAC) Application of
This product has the characteristics of the decision of its water supply, high-purity water treatment, paper manufacturing and high-end cosmetics preferred position, in addition to turbidity effects of the active ingredient by comparison, is 1.5-3 times that of aluminum sulfate, used in the paper than the traditional use of aluminum sulfate paper sizing process may be extended shelf-life of low temperature and low turbidity and high turbidity water, flocculation ordinary inorganic coagulant unmatched.
PAC in the following areas purity is an ideal choice for use:
1, city water treatment
2, paper sizing
3, high purity water treatment
4, oilfield re-injection water treatment
5, cosmetics manufacturing, catalyst carrier
6, cast molding, pharmaceutical fine
Poly Aluminium Chloride (PAC), is a water-soluble inorganic polymer between AlCI3 and Al(OH)3, its general formula is [Al2(OH)nCl6-nLm], of which m represents the degree of polymerization and n represents the degree of neutrality of PAC products. This product has strong bridge adsorption performance. During the hydrolysis process, condensation, adsorption, precipitation as well as other physical and chemical processes also occurs at the same time. The fundamental difference between poly aluminium chloride and traditional inorganic coagulants is that the traditional inorganic coagulants is low molecular crystal salt, but the structure of poly aluminium chloride is composed of polycarboxyl complex with variable morphology, it has high speed of flocculating and precipitating, suitable for wide PH range, no corrosive to pipeline equipment, obvious water purification effect, it can effectively remove chromaticness, Suspended Solids(SS), Chemical Oxygen Demand(COD), Biochemical Oxygen Demand(BOD) and such heavy metal ions as arsenic and mercury in the water. This product is widely used in drinking water, industrial water and wastewater treatment field.
