Q:What's the ingredient of burnt lime?
The calcination of lime is actually the process of decomposition of calcium carbonate, so lime is made up of calcium oxide! Again, the burnt lime is made of calcium oxide.
Q:The difference between alkali lime and quicklime
Can not be absorbed by concentrated sulfuric acid, because hydrogen sulfide gas will be oxidized to sulfur dioxide by concentrated sulfuric acid, while concentrated sulfuric acid itself is reduced to produce sulfur dioxide gas, that is to say, a new impurity.
Q:Limestone, gypsum, lime three, what is the relationship?
It has a good solidification and white, so often used for wall treatment, gypsum is calcium sulfate, and it also has a good solidification, it is also often used for building materials or model making. It is produced by natural minerals.
Q:The difference between gypsum and lime
Lime is CaO calcium oxide, calcium hydroxide in water to generate lime, calcium hydroxide is Ca (OH) 2, alkaline, drops of phenolphthalein solution is red
Q:What does lime mean?
Lime production: the original lime production process is the limestone and fuel (wood) layered laying, firing for a week to get calcined. In modern times, mechanical, semi mechanized kiln, rotary kiln, boiling furnace and other equipment are used for production. The calcination time is correspondingly shortened, and the production of lime with rotary kiln only takes 2~4 hours, and the production efficiency can be increased by more than 5 times compared with the vertical kiln. There have also been cross flow type, double slope type and oil burning circular kiln and short rotary kiln with preheater, etc., with remarkable energy-saving effects, such as coal, coke, heavy oil or liquefied petroleum gas, etc..
Q:How long will it take to sterilize the water in the fish pond?
Lime as the main component of calcium oxide, usually method was mainly composed of calcium carbonate rock, calcined at high temperature, then decomposition of carbon dioxide and calcium oxide (chemical formula: CaO, which is also known as lime, marble). Reaction equation for the dissolution of lime in water: CaO+H2O=Ca (OH) 2.
Q:What's the use of limestone for thermal power desulfurization?
Thermal power plant desulfurization limestone is because the thermal power plant using the wet limestone desulfurization technology, limestone as a desulfurization agent
Q:How to distinguish lime mortar and cement mortar wall surface
Mixed mortar also added to other materials (such as lime paste, mortar, masonry) and its performance is good, commonly used in the wall "moistureproof layer" above the brick masonry and plastering wall (as with kitchen and toilet can not use plaster walls.)
Q:Will the fish pond be sprinkled in three months?
Since the dose: pond with water (1m water depth) per 667m - 150kg, lime water after the opening of the pool splashing. Dry cleaning (10cm water depth) per 667m - 75kg, lime water after the opening of the pool splashing. Special reminder: it is best to use block lime, it can emit a lot of heat energy, and should be immediately used, placed too long will reduce efficacy. Water hardness, bottom mud, lime pondthe will effect, should be appropriate to increase the amount of. Lime pond drug generally after 5 ~ 7 days away, put the fish before the test.
Q:What is the reaction of a small amount of limestone to dilute hydrochloric acid under heating?
The main component of limestone is calcium carbonate.Calcium carbonate reacts with dilute hydrochloric acid to produce calcium chloride and carbonic acid, which is unstable and readily decomposes into carbon dioxide and water. Therefore, calcium carbonate reacts with dilute hydrochloric acid to produce calcium chloride, carbon dioxide and water.
We can produce quality limestone 6 million tons (CaCO3>=97%,stable), active calcium oxide 1.50 million tons, light calcium carbonate 100 thousand tons and calcium hydroxide 100 thousand tons every year. And our products has been exported to Asia, Africa, Australia, America, etc.. and we sincerely hope to cooperate with the clients from all over world. Hope we would gain together in the future!
