First of all, we must have a certain understanding of the physical and chemical properties of calcium oxide in order to make it more useful. Calcium oxide is a kind of calcium with a content of 85%. The powder is generally 150-200 mesh, and the color is generally white. Because it is easy to produce, the price is generally cheap. Some high-purity calcium oxide is generally about 325 mesh and has good solubility. If stored for a long time, the content of calcium oxide will gradually decrease. Because it is very soluble in water, Hebei calcium oxide will be used to keep food dry. General food preservatives contain calcium oxide and some iron oxide. You must pay attention not to let children eat them secretly at ordinary times.
How is Hebei calcium oxide produced? It needs to be desulfurized during production,how to choose the special grinding machine for dry desulfurization stone powder used by Hebei calcium oxide manufacturers? Generally, the calcium oxide products produced by our grinding machinery are used as follows: they play a very important role in the dehydration of steel, desiccant, leather, etc. Therefore, be sure to choose a strong manufacturer that can provide you with good solutions for machine protection, installation and maintenance. Usually calcium oxide meets water to form calcium hydroxide, which can absorb carbon dioxide in the air. Adding calcium oxide to acid waste water or heavy metal waste water can make acid waste water neutral; it can absorb sulfur dioxide in boiler flue gas, so that the sulfur content of discharged flue gas meets environmental protection standards; kill bacteria and viruses, and remove ammonia nitrogen from water, etc.
