1 used in the construction industry: when lime is mixed with sand and cement, high strength concrete can be formed,2, lime dissolves in water, used for whitewashing, forming white walls, beautiful and disinfection,3. Lime is soluble in water and can be used for environmental disinfection,4, lime is dissolved in water, the formation of Bordeaux and copper sulfate mixture, for the treatment of diseases of fruit trees.5, for flue gas desulfurization, can also be directly mixed with coal, used for desulfurization,6, the steel industry, smelting iron and steel also need lime.
Electric lime is the chemical enterprise to calcium carbide as a by-product of the production of chemical products of raw materials, it is used for water discharge, by flow into the drain tank, is plastic drain, dig out the storage or directly discharged into the ash storage field, a large area of natural dehydration. Due to the production of calcium carbide raw materials, chemical composition, production processes and other reasons, the content of lime produced in different parts of the country is not the same. The manufacturers of quantitative analysis showed that the main component is Ca, Ca (OH) 2 and CaCO3 mixed form, the impurities of the toxic substances in the arsenic cyanide As, CN content is lower than GB12502-90 pollution control standards prescribed by the state, and provide a reliable basis for the safe use of electric lime.
Electric lime and lime in nature is consistent with Cao and MgO as the main component, detecting the site laboratory for many times, content between 50~56%, through the test that electric lime has better activity, have good performance of cemented soil strength, can form a certain dose of lime, calcium carbide strength can meet the technical specifications of the lime stabilized soil in the highway construction requirements, low liquid limit silt 7 days compressive strength is low, low liquid limit clay 7 days compressive strength is high, but compared with the same dose of lime to low, suitable for low grade highway subbase or highway roadbed improved soil by lime as a substitute (high plasticity clay can be used for the base of high grade highway), Cang Huang highway roadbed with electric lime soil improvement, soil CBR value increased from 4~6% to 40~60%, digging test has very high strength, subgrade The deflection value is 40~70 (0.01mm).
