Improve sludge sedimentation effect and treatment effect. Hydrated lime used for wastewater treatment is really alkaline. Ferrous sulfate is acidic. Under alkaline conditions, ferrous sulfate forms the colloid of ferrous hydroxide in the water body. While accelerating the oxidation of ferrous sulfate, it also enhances the reducibility, and can better reduce the chromaticity groups and complexes in the water body. In order to prevent the total excess reducing substance ferrous hydroxide in the water body from increasing COD, so as to control the pH value within the range of complete precipitation of ferrous.
You can use this reaction. It can also identify what the non-metallic oxide belongs to. Calcium oxide can react with certain salts. It can generate another alkali and another salt. It can react with some acids to form salt and water; It is also a method of making calcium salt, and can also identify acids. Calcium hydroxide plays a role in environmental protection and purification. Calcium hydroxide is a strong alkali, which has the general property of alkali, and can neutralize acidic wastewater or metal wastewater, making acidic wastewater neutral; It can absorb sulfur dioxide in flue gas.
But it is widely used, for example, when making ceramics, some can be added as raw materials. Next, let's take a look at the application of the product in this industry. Calcium oxide brick stabilized by titanium dioxide. It can be used as lining material of rotary kiln for molten phosphate ore. Calcium hydroxide has excellent resistance to metal corrosion and is an important container for smelting non-ferrous metals, such as high-purity platinum and uranium. In addition to the above, it is also suitable for insulation sleeves for arc melting or containers for balancing experimental angles.
Increase the content of trace elements in soil, and provide sufficient calcium or magnesium for crops. Put an appropriate amount of calcium oxide in the soil, and it can form calcium hydroxide when meeting water, which plays a role in promoting the aggregation of soil colloid, and the soil is easy to form a granular structure. Therefore, it can improve soil viscosity, maintain soil moisture, improve soil permeability, and is more conducive to crop growth. Introduction to the scope of application of high-purity calcium hydroxide We know that high-purity calcium hydroxide is a strongly alkaline substance.
It emits a lot of heat, which can effectively inhibit pathogenic bacteria and kill insect eggs. After long-term cultivation in farmland, there are a lot of pathogenic bacteria and insect eggs in the soil, which are very harmful to the growth of crops. At this time, if quicklime is spread in the field, it will react with water to generate strong alkaline calcium hydroxide, which can play a role in disinfection. Because both pathogenic bacteria and eggs contain protein. Protein will lose its activity when encountering strong alkali, so the effect is very obvious.
Other additives can be mixed together. The change of its addition proportion affects the vulcanization system of rubber; The rubber filled with fine and micro calcium hydroxide can obtain higher expansion strength, wear resistance and tear strength than pure rubber. The finer the particles are. The expansion strength, flexibility and tear strength of rubber are improved more obviously. The expansion strength of rubber can be greatly improved; Calcium hydroxide can adjust the hardness. The quality of rubber is highly valued. The production cost of rubber is high.
