Xintai Group: Tell us about the key characteristics of calcium aluminate powder

2022-08-18

Calcium aluminate powder is the raw material of water treatment agent, with strong vitality, its use is very wide, calcium aluminate powder manufacturer shows that calcium aluminate powder is mainly used in the production and manufacture of polyaluminium chloride, can also do refractory insulation materials. Calcium aluminate production process can be achieved with calcium aluminate powder cement rotary kiln.

Calcium aluminate production process needs to be achieved by calcium aluminate powder cement rotary kiln.

Calcium aluminate cement rotary kiln This rotary kiln equipment is composed of cylinder section, support equipment, support equipment with retaining wheel, transmission system, movable house, kiln end sealing device, ignition equipment and other components. This cement rotary kiln has the advantages of compact structure, reliable operation and very easy to manipulate the processing.

The thickness of the stainless steel plate of the kiln shell is about 40mm, and the thick steel plate of the kiln shell is thicker around the tire ring, because the load is very heavy. Inside the kiln shell, there is a layer of insulation bricks of about 200mm. When the kiln shell is in operation, due to the continuous high temperature and the load, the shell will have an elliptical deformation, which will cause working pressure on the kiln bricks and endanger the service life of the bricks.

At the end of the kiln there is about one meter long area of cone shape, so that the English material coming from the preheater inlet chamber can enter the furnace relatively smoothly.

Xintai Group: The key characteristics of calcium aluminate powder are shown as follows:

1. small heat release, high sodium hydrosulfate, low calcium hydroxide, can produce solid polymeric aluminum chloride that manufactures sodium hydrosulfate beyond 30%.

2. Acid consumption and cost reduction, overcoming the problem that calcium aluminate cannot directly produce and manufacture aluminum polymerization with sodium bisulfate over 30%.

Calcium aluminate powder composition uniform, low melting point, melting faster, can reduce smelting time; does not contain fluorine, does not corrode the furnace charge and steel ladle; structure high density, does not absorb moisture, conducive to storage and transportation warehouse storage; because the physical phase is smooth, into slag fast, can reduce the smelter dust hazards, smooth refining process; not peroxide, nitrogen, carbon and other residues, beneficial to enhance the quality of construction steel.

How to precisely test the aluminum content in calcium aluminate powder?

Calcium aluminate powder is mainly used in the production of aluminum sulfate, polymerized aluminum, crystalline aluminum raw materials, is an alternative product to aluminum hydroxide powder, water treatment agent manufactured by acid solubilization method, making an excellent substitute for saving resources. It has the advantages of cheap price and high aluminum content.

Xintai Group: bring the way to measure the aluminum content in calcium aluminate powder

1、Weigh the quality of calcium aluminate powder precisely with balance scale.

2、Melt calcium aluminate sufficiently in water.

3、Add sulfuric acid drop by drop to the aqueous solution, (the condition should occur first white precipitate, after the white precipitate gradually disappears) terminate when it is observed that the white precipitate now begins to fade.

4、Add too much sodium hydroxide dropwise to the above mixture. (The phenomenon is that the white precipitate gradually increases) Stop when it is observed that the white precipitate will no longer lift.

5、Overconsider, take the precipitate and wash it, and weigh its quality precisely. [The precipitate is Al(OH)3]6, calculate the quality of Al according to the data already known, and calculate its mass concentration.

This trick is convinced that the feasibility analysis is still possible, despite the slight inconvenience.

Xintai Group: Thanks for watching, let's see you next time.
