27%, 28%, 29%, 30% Polyaluminum Chloride Difference Points Content 27%, 28%, 29%, 30% Polyaluminum Chloride Differentiation To find out the content of 27%, 28%, 29 %, 30% PAC, it is necessary to understand the content of PAC: the content of aluminum oxide, the difference is that in the final analysis is the use of different raw materials, the content of 27% of the PAC The raw material used for the aluminum is 45% of the content of the calcium aluminate powder, the raw material used for the 28% of the polyaluminum chloride is 48% of the raw material of calcium aluminate powder, the raw material used for the polyaluminum chloride content of 29% Content of 51%, 30% of the content of raw materials used in aluminum chloride powder calcium aluminate content of 52-54%. The difference in the content of these raw materials determines the difference between the content of 27% 28% 29% 30% of PAC, followed by the two raw materials bauxite, bauxite and calcium aluminate dosage is also much The impact, such as bauxite dosing addition of calcium aluminate less, then the content of polyaluminum chloride is different. In addition, the influence of temperature on the polyaluminum chloride is well known, and it is greatly affected by the low temperature and low turbidity, and less affected by the high temperature and high turbidity. When the temperature reaches -5 ° C The flocculation effect will be affected. Where the temperature is too high, the impact is rather small. The main reason is that the final process of the production of the PAC products is drying. However, it should be noted that excessive Temperature will make the moisture in the air deep into the PAC, affecting its use effect. Many molecular structures from a very active state to the static state of the transition are often due to temperature changes, from the internal structural analysis of polymeric aluminum chloride is also within this category, the molecular structure at a temperature of 5-20 ℃ When the molecular structure of its most stable, when the temperature dropped below zero when the slow molecules began to stop activities, it affects the use of polyaluminum chloride effect, the most direct manifestation of the flocculation effect is not ideal, it is difficult The formation of alum, at the same time when the adsorption is not up to the desired adsorption effect, further affecting its precipitation effect, and in winter weather, in many places the temperature will drop below zero, our advice is: If you need to use Polyaluminum chloride products, at about 10 o'clock in the liquid debugging, at 3 pm before the launch, the general will not affect its effectiveness.
