This product is used in different industries and has different functions. We need to do a good job of sealed storage in the process of daily use. Now, let's see why we need sealed storage. Calcium hydroxide is affected by carbon dioxide in the air. Produce calcium carbonate. It is also based on the principle that the clarified lime water is introduced into carbon dioxide to produce impurities. It is very sensitive to temperature, and the external temperature often changes to some extent. If there are acid substances in the environment.
Generally, during the curing process, the volume of lime will be doubled or doubled, releasing a lot of heat energy. In quicklime. The hydrated lime powder with fine particles and uniform dispersion can be obtained by evenly adding 60%~80% water. If excessive water is used for curing, lime paste with certain consistency will be obtained. The hardening of calcium oxide is carried out in two processes together. The lime slurry is dry due to water transpiration or absorption, and capillary pressure occurs in the pore network of the slurry.
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.
Calcium oxide can increase the activity of microorganisms in soil and the nutrients of calcium and magnesium ions. Spreading quicklime on farmland can improve the soil environment, increase the activity of beneficial microorganisms in the soil, strengthen the decomposition and digestion of beneficial microorganisms, increase the release of organic phosphorus in the soil, and improve the nutrient composition of the soil. Improve soil properties and increase crop yield. Quicklime contains calcium oxide or magnesium oxide. Adding an appropriate amount of Shaanxi calcium oxide into the soil can increase the content of calcium or magnesium in the soil.
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.
