Lime powder is a building material that we often see or use in daily life, so it should be familiar to us. Lime powder, as an important building material, plays an important role in our construction industry. So what kind of material is lime powder ? How much is a ton of lime powder ? What are its classifications and uses? Today I will give you a brief introduction about how much is a ton of lime powder, lime powder and its classification and use, I hope to help everyone.
Introduction of lime powder
First of all, let's take a look at the basic situation of lime powder, and have a simple understanding of it. Lime powder is a white powdery substance, and its application is very extensive, the most common is used in the construction industry, because it is an important building material. Lime powder also has a familiar name, that is, industrial calcium carbonate. This is named because of the composition of lime powder. Lime powder plays an important role in the modern construction industry.
Lime powder classification
White powdery substance with calcium carbonate as the main component. The scope of application is very wide, the most common is calcium carbonate used in the construction industry, that is, industrial use; the other is food-grade calcium carbonate, which is widely used as a common calcium supplement. There are two types of calcium supplements commonly used for calcium supplementation: one is heavy calcium carbonate, which is limestone crushed to a certain fineness by a lime mill and used as a food additive; the other is light calcium carbonate, which is Limestone is made by calcination. The report claims that Jiangsu's "Brightening Brightener" actually uses calcium carbonate.
Lime powder use
Lime is widely used in civil engineering, and its main uses are as follows:
(1) Lime milk and mortar slaked lime powder or lime paste are mixed with a large amount of paint. Use lime paste or slaked lime powder to prepare lime mortar or cement-lime mixed mortar for masonry or plastering works.
(2) Lime-stabilized soil Mixing slaked lime powder or quicklime powder into various crushed or originally loose soils, the mixture obtained after mixing, compacting and curing is called lime-stabilized soil. It includes lime soil, lime stabilized gravel soil, lime gravel soil, etc. Lime stabilized soil has certain strength and water resistance. Widely used as the foundation of buildings, ground cushion and road pavement base.
(3) Silicate products use lime (slaked lime powder or quick lime powder) and siliceous materials (sand, fly ash, volcanic ash, slag, etc.) as the main raw materials, and can be made into bricks after batching, mixing, forming and curing. , Block and other products. Because the internal gelling material is mainly hydrated calcium silicate, it is called silicate products, commonly used are sand bricks and fly ash bricks.
How much is a ton of lime powder
Due to different lime powder brands and manufacturers, of course, lime powder prices will vary. The price of lime powder is about several hundred yuan / ton. In order to be fooled, I suggest you to go to the physical store to investigate before buying.
Note: This price is for reference only! Due to different regions, of course, the price will vary. If you want to know more about the relevant price details, please refer to the local dealers!
Lime powder production process
The original lime production process is to lay limestone and fuel (wood) in layers, and fire it for one week. In modern times, mechanized and semi-mechanized vertical kilns, rotary kilns, and boiling furnaces are used for production. The calcination time is also shortened accordingly. It takes only 2 to 4 hours to produce lime with a rotary kiln, which can increase production efficiency by more than 5 times compared with vertical kiln production. Processes and equipment with significant energy-saving effects, such as cross-flow, double-slope and oil-burning circular vertical kilns and short rotary kilns with preheaters, are also expanded to coal, coke, heavy oil or liquefied gas.
Packed in plastic woven bag lined with polyethylene plastic film bag, net weight 25kg per bag. It should be stored in a dry warehouse. Keep away from moisture. Avoid co-storage and transportation with acids. Protect from rain during transportation. In case of fire, use water, sand or general fire extinguisher to extinguish. White powder with fine physical properties. The relative density is 2.24. Calcium carbonate is formed by absorbing carbon dioxide in the air. Soluble in acid, ammonium salt, glycerin, slightly soluble in water, insoluble in alcohol, strong alkaline, corrosive to skin, fabric, utensils and other substances. Its aqueous solution is commonly known as lime water.
Editor's summary: In fact, there are many uses of lime powder. What we introduce here are only some of its more important functions. In addition, lime powder can be divided into different types according to different standards. What we introduce here is classified according to the composition of lime powder.
