Check the production and packaging to ensure that it is within the warranty period. Whether quality inspection is paid attention to. We need to check the fineness and whiteness, whether it is affected by moisture, and whether there is agglomeration. Whether there is discoloration. Whether there is protection. Because it is corrosive and toxic, we need to wear masks and gloves for protection before use. Why should calcium hydroxide seal the hydrated lime used in our daily life and production? It is called calcium hydroxide in the chemical industry.
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.
Make the sulfur content of discharged flue gas meet the environmental protection standards; It can help coagulate colloidal particles in wastewater. It is also used as a particle nuclear weight enhancer to accelerate the separation of insoluble matters; The emulsion wastewater can be destabilized and demulsified by adjusting the PH value; It can effectively remove phosphate, sulfate, fluoride and other anions; Compared with the effect of wastewater treatment, it is a conventional alkaline agent for wastewater treatment. Compared with the 30% calcium hydroxide alkali solution, the price of each ton of sodium hydroxide alkali solution is equivalent to that of each ton of calcium hydroxide powder.
With it, the volume of rubber products is increased, and the production cost of rubber or synthetic rubber is saved. We all know that rubber products need strict quality requirements, and because it can't be used for a long time, it needs to add some additives to maintain its performance. What role does it play in rubber filling? In the formulation of rubber products, it is often necessary to add several portions of calcium hydroxide. It has good dispersibility in light colored fillers. It can be mixed with rubber in any proportion.
In case of contact with eyes, immediately raise the eyelids, flush with a large amount of flowing water or physiological saline, and seek medical care. Because calcium oxide has a wide range of uses and low application cost, most building materials and industrial wastewater treatment are currently used in large quantities, so protection and some emergency treatment should be done in the use process to avoid harm to health. Rubber filling needs the help of calcium hydroxide. As one of the fillers in the rubber industry, calcium hydroxide is largely filled in rubber products.
Generally speaking, the setting time of cement will be shortened when the content of free calcium oxide is high. Pure quicklime is added into the cement after single calcination. Because there is no influence of impurities and oxides, it has great hydration. According to the introduction of calcium oxide manufacturers, both initial setting and final setting will be shortened with the addition of free calcium oxide content. Industrial limestone is calcined at high temperature, and its structure is fine and dense under the influence of silica, ferric oxide, aluminum oxide and other substances.
