Q:What is the difference between lime and cement? What are the main ingredients? What is the use?
The main component of Portland cement, quicklime is the main component of calcium hydroxide, lime is the main component of calcium carbonate
Q:What color is limestone?
Limestone is the main raw material in the production of quicklime. Carbon dioxide (CO2) to clarify lime (CaOH2) becomes muddy. Lime and limestone used as building materials, it is also an important raw material in many industries. The limestone can be directly processed into stone and fire into lime.
Q:Used to make cement is gypsum or limestone
All have. Cement by limestone, clay, iron ore powder mixed in proportion, at this time the mixture called raw materials. And then the calcination, the general temperature of about 1450 degrees, the calcined product called clinker. Then the clinker and gypsum are ground together in a mixture.
Q:Density of quicklime powder
Quicklime powder is divided into several. The lime used in the decoration project is made of lime, lime and lime powder. Building quicklime is the main component of calcium carbonate as raw materials (such as limestone, etc.), in the sintering temperature below. According to the chemical composition, it can be divided into calcareous quicklime and magnesia quicklime. The content of Magnesium Oxide is less than or equal to 5%, and the content of Magnesium Oxide is more than 5%. Building lime is divided into superior products, first-class quality and grade three. Superior product the pulp capacity of not less than 2.8L / kg grade; the pulp capacity of not less than 2.3L / kg; qualified slurry is not less than 2.0L / kg.
Q:Why does lime gypsum method desulfurization bubble
The dehydration system or waste water treatment system can not be put into normal operation, which makes the quality of absorption tower gradually deteriorate;5 the boiler combustion is not good, fly ash in some carbon particles or tar with smoke into the absorption tower;6 in the course of operation, the phenomenon of the sudden trip of the oxidation fan suddenly appeared, and the gas-liquid equilibrium of the absorption tower was destroyed, resulting in a large amount of overflow of the absorber.
Q:Limestone and dilute hydrochloric acid can not make clear lime water becomes muddy, why
Limestone and dilute hydrochloric acid reaction is the production of CO2, and then into the Ca (OH) 2, so that the clarification of lime water turbidity, the formation of CaCO3 precipitation (turbidity). The condition is in the alkaline solution; and can not make clear the water becomes muddy, that is, the solution is acidic will also generate precipitation, can dissolve the reason.
Q:Wet grinding machine using limestone particle size is not the smaller the better?
The size of limestone used in wet mill is smaller, the better. The smaller the particle size, the higher the efficiency of the wet mill.The main component of limestone is calcium carbonate. Lime and limestone are widely used in building materials and industrial raw materials. The limestone is directly processed into stone and fired into quicklime. Quicklime absorption of moisture or water to become ripe lime, the main component is calcium hydroxide, lime prepared by the deployment of lime slurry, lime paste, used as coating materials and tile adhesives. Limestone reacts with all strong acids to produce calcium salts and carbon dioxide. The rate of reaction depends on the impurities in the limestone and the size of their crystals. The higher the impurity content, the larger the crystal, the smaller the reaction speed.
Q:How the lime was made and how it came
Raw materials and production of limeCalcium carbonate as the main component of natural rocks, such as limestone, chalk, dolomite limestone, can be used to produce lime.The main component of the natural calcium carbonate rock, calcined at appropriate temperature, the removal of the decomposition of carbon dioxide, the resulting calcium oxide (CaC) as the main component of the product that is lime, also known as quicklime.In the actual production, in order to speed up the decomposition, calcination temperature often increased to 1000 ~ 1100 C. Due to the large size of limestone raw material or the uneven distribution of temperature in the kiln, lime and lime are often contained in lime. The calcium carbonate in the lime is not completely decomposed, and the adhesive force is not used. The burnt lime structure is dense, the surface is often covered with a layer of molten material, and the curing is slow. Because the production of raw materials often contain magnesium carbonate (MgCO3), because this lime also contains minor components of Magnesium Oxide (MgO), according to the number of Magnesium Oxide content, lime into calcium lime (MgO = 5%) and magnesia lime (MgO>5%).Quicklime is white or gray block, in order to facilitate the use of bulk lime often need to be processed into quicklime powder, lime powder or lime cream. Lime powder is composed of massive pulverized quicklime obtained by fine powder, the main ingredient is CaO; lime powder is lump lime with water curing powder obtained, also called slaked lime, its main component is Ca (OH) 2; lime paste is lump lime with more water (about 3 - 4 times the volume of lime) obtained by curing paste. Also called lime slurry. Its main component is Ca (OH) 2.
Q:How long does it take for limestone to be decomposed in rotary kiln
The main requirements for the quality of limestone used in industry are:(1) the requirements of high content of calcium carbonate components, the general requirements of more than 97%(2) the structure of grain should be small, because the small grain of lime Shi Jing is not tight, and in the case of containing organic matter, porous formation of combustion of organic matter, carbon dioxide separated easily, so it is convenient to calcine.(3) less impurities, particularly harmful ingredients such as silica, Magnesium Oxide, alumina, iron oxide, sulfur and phosphorus, etc. these ingredients in the limestone, if there are one percent, to the calcined lime, is the eighteen percent
Q:Limestone is used to make glass?
The glass melting process includes: formation of silicate, formation of vitreous body, clarification, homogenization and coolingLimestone, dolomite, soda, Glauber's salt will produce gas, so that it is not only the glass formation and harmless, but also conducive to the refining of glass and homogenization, factory general also added a part of clarifier, generating a lot of bubbles, bubbles in the floatation process, combined with small bubbles, this is the glass fining mechanism.
