Xintai Group briefly explained below the use of calcium aluminate powder

2022-06-28

Calcium aluminate powder has the appearance of off-white solid powder, which is easily soluble in acid and has high activity with alumina, and can effectively dissolve 90% of alumina when reacting with hydrochloric acid.

At present, calcium aluminate powder is mainly used as raw material for the production of water treatment flocculants such as polymeric aluminum chloride and ferric polymeric aluminum chloride, followed by raw material for the production of refractory materials and refractory bricks.

Calcium aluminate powder mainly uses aluminum ore and lapis lazuli (also known as travertine). After crushing and grinding, the two ores are put into rotary kiln in a certain proportion, and the finished calcium aluminate powder is made by high temperature heating reaction. Calcium aluminate powder uses aluminum ore to react with calcite, so the content of active calcium and alumina is high, and in the production of polymeric aluminum chloride, alumina can be effectively dissolved after reacting with hydrochloric acid, and the active calcium helps the reaction more effectively.

Calcium aluminate powder in the production of polymerized aluminum chloride is an important raw material for the production of polymerized aluminum chloride. The quality and price of calcium aluminate powder affect the production cost and product quality of polymerized aluminum chloride, so it is crucial to choose reliable and stable calcium aluminate powder.

Xintai Group: How to judge the content of polymeric aluminum chloride by color

Usually when we buy polymeric aluminum chloride, we judge the good or bad of polymeric aluminum chloride through three indicators: alumina content, water insoluble matter and alkalinity, but the content can be judged visually from the appearance, today I give you a science.

White polymeric aluminum chloride is drinking water, iron-free high purity or food grade polymeric aluminum chloride, the content of up to 31% or more, the main raw material is aluminum hydroxide powder and hydrochloric acid, using spray drying method, are high-end products, the price is high.

Polymeric aluminum chloride is used for sewage treatment and drinking water treatment, the content is 28%-30%, the raw materials of polymeric aluminum chloride for drinking water treatment are alumina powder, hydrochloric acid and calcium aluminate powder, there are two processes, one is spray method, the other is plate and frame press filter, there are strict requirements for heavy metals in drinking water, brown and earthy polymeric aluminum chloride raw materials are calcium aluminate powder, hydrochloric acid, bauxite and iron powder, the general content In about 26%, mainly used in sewage treatment, because the iron content inside is relatively high, so the color is dark brown, if the iron content reaches 3%, it is called polymeric aluminum chloride iron, it is effective in sewage treatment.

Xintai Group manufacturers aim to provide effective water purification agent products for the majority of users and save big application costs.

Well, thank you for watching, if you have other questions can consult the editor, in addition, our company has calcium aluminate powder, aluminate cement, high activity bauxite, poly aluminum chloride, poly aluminum chloride iron, if you need to remember to consult, let us see you next time.
