Mine particles of calcium hydroxide

Mine on the particles of calcium hydroxide, calcium hydroxide, a white granular, mine rescue team with calcium hydroxide, refuge chamber is divided into a variety of calcium hydroxide, calcium hydroxide, are mine, and building on the use, as well as medical use, their different uses, can not be mixed, or dangerous. In mines calcium hydroxide is mainly used in self-rescuer, respirators, air cleaning devices, so we can call rescuer calcium hydroxide, calcium hydroxide respirator in the refuge chamber are also widely used, but in the refuge chamber calcium hydroxide and the use of self-help, respirators, air purification devices are different. Role of calcium hydroxide to absorb carbon dioxide mainly. Carbon dioxide absorption rate ≥30% Loss on drying: 16% -18% white striped cylindrical particles easily absorb carbon dioxide, into the container after absorbing a large area, low resistance, ventilation uniform and effective. Calcium hydroxide in respirators and self-help in the use of respirators are generally two hours and four hours, two hours of general use about 1.6 to 2.0kg, 4 hrs General by 2.3 to 2.8kg ,, rescuer general 30 minutes, 45 minutes, 60 minutes, 120 minutes. Rescuer said the following about the amount of calcium hydroxide. Used for 30 minutes to save themselves 0.35kg calcium hydroxide, 45 minutes to save themselves Used 0.55kg, 60 分钟 self Used 0.6kg, 120 minutes 0.65kg calcium hydroxide. Know how much usage, and I would like to explain a few of its main parameters. Carbon dioxide inhalation 33% yield to 36%, moisture content: 16% to 20%, particle size: columnar grains, Dimensions: sectional diameter from 2.5 to 3.5, length: 4-7.
