Factors that influence the viscosity of polyaluminum chloride Factors that affect the viscosity of polyaluminum chloride. Nowadays, many people wonder why there is no other substance besides PAC which can play a good flocculation effect, mainly because the chemical has better viscosity in water. What are the main factors that affect the viscosity of the chemical? ? 1, the molecular form of aluminum chloride dissolved in water in the form of special can affect the handling of easy viscosity, usually long chain than the words in the chain of short-chain viscosity to be larger. 2, molecular weight The molecular weight here is 1 mol in the chemical weight, the greater the molecular weight of the relative viscosity is higher. 3, the density of the charge We all know that chemical reagents will dissolve in the water there will be yin and yang of the points, to mention a few of you are particularly familiar with 2-valent iron ions, trivalent aluminum ions, these ions with a certain charge, charge number The higher the solution the higher the viscosity. 4. Electrolyte Type and Concentration Electrolytes in water have hydrogen ions and hydroxide ions. If the charge density is too large, the ions will be mutually exclusive and the amount will decrease the length of the stretching chain, which will affect the concentration of polyaluminum chloride.
Which can effectively remove the aluminum ions in the source water and residual free aluminum ions in the water after coagulation of the aluminum salt
On dry, moisture-proof place, the general shelf life of two years, but the use of results will be less then, little effect.
Because PAC itself is a flocculant flocculant, customers use polyaluminium chloride is to reduce the COD in the sewage, BOD, how to increase, then how to deal w
k, meat processing wastewater f, Boiling Pyrolysis Boiling pyrolysis of crystalline aluminum chloride at 170 ° C, brewing waste water, metallurgical wastewater
Yeah, also known as caustic soda sodium hydroxide, which together with the PAC will produce the following reaction 3NaOH + Al (Cl) 3 = Al (OH) 3 (colloid) + 3Na
