Abstract

The invention provides a process for preparing pure natural ultrafine calcium powder. The process comprises the following steps: selecting materials, cleaning, crushing, calcining, grinding, hydrolyzing and performing superfine grinding. According to the invention, calcining under inert gases is not needed, the combustion is sufficient, and the heating time is greatly shortened and is only several hours. Therefore, the production efficiency is improved, the labor time is reduced, the product cost is reduced, and the increasingly extending requirement of the market can be met. The calcined products are hydrolyzed, so that lots of heat energy is released, the instability in the transport and storage process is reduced, and thus the product has high safety. Moreover, the substances such as calcium hydroxide belong to slight soluble strong base substances in water, so the product has long-acting good bacteriostatic action. Meanwhile, the hydrolyzed product is ground again, so that the grinding time is shortened, the abrasive particles can be ground into a narrower range, the acting superficial area is enlarged, the effect is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to a preparation process of an acid neutralizer, in particular to a preparation process of pure natural ultrafine calcium powder. Background technique [0002] Because modern people eat more fine grains, fish and other highly acidic foods, and live a stressful life, staying up all night, coupled with the influence of water and air pollution, lack of exercise and bad emotions, they often have an acidic body. In terms of drinking water, most of the water and beverages that people drink at present are acidic. According to biologists' reports, the water in the adult human body accounts for about 60%-70% of the body weight. This includes blood and body fluids. Therefore, everyone needs to add 8 glasses of water every day to maintain physical fitness. However, the processing technology of purified water makes the minerals in the water-including minerals that can neutralize the acidic substances in the body. When purified water is ex...
