What Is Iron Free Aluminum Sulfate

 

 

Iron free aluminum sulfate has good filtration performance, can improve the utilization rate of equipment and reduce the cost of water treatment. Aluminum sulfate will not produce reaction, easy to operate, and has no corrosiveness to water control equipment and pipeline. Aluminum sulfate is widely used in the purification of drinking water and industrial water. Aluminum sulfate is also a very useful mollusc insecticide, which can kill slug in spain. Aluminum sulfate hydrolysis can produce aluminum hydroxide, which can be used to regulate soil ph value. Iron free aluminum sulfate is an inorganic flocculant widely used in water supply and drainage treatment. With the continuous improvement of people's living standards and the deterioration of various natural water environment conditions, people put forward higher and higher requirements for the water treatment industry, especially the flocculation purification of tap water.

 

Advantages of Iron Free Aluminum Sulfate

 

Reduces the corrosion of the system
Iron free aluminum sulfate is only suitable for acid sizing, while aluminum chloride can be used for sizing in acidic and neutral environments, which greatly reduces the corrosion of the system and makes white water treatment easier.


Widely use
Iron free aluminum sulfate is also widely used in the production of clarifiers, petroleum deodorizing and decolorizing agents, concrete waterproofing agents, paper forging white, titanium dioxide post-film treatment, and catalyst carriers.


Purifying agent
In addition, it can also be used as a purifying agent for turbid water, or as a precipitant, fixative, filler, etc. It can even be used as a raw material for antiperspirant cosmetics (astringent).


Reduces the production cost
It can be filled with cheap calcium carbonate filler, which not only reduces the production cost and improves the whiteness and folding resistance of the paper, but also overcomes the unavoidable shortcomings of synthetic rubber (such as akd, etc.) (such as slipping, difficult to control the sizing degree, etc.)

Characteristics of Iron Free Aluminum Sulfate for Medicinal and Paint Applications

 

 

The solid product is white granular or massive, with white shiny crystals. Stable in the air. At 86.5 ℃, some crystal water is lost, and at 250 ℃, all crystal water is lost. When heated, it expands violently and becomes a sponge-like substance. When burned to red heat, it decomposes into sulfur trioxide and alumina. It is weathered when the relative humidity is about 25% lower.

 

It is easily soluble in water, almost insoluble in ethanol, and the solution is acidic. After long boiling, insoluble basic salt precipitates. The relative density is 1.62. Iron-free aluminum sulfate for iron-free paints is a widely used industrial reagent, and is usually confused with alum (both iron-free aluminum potassium sulfate for paints with 12-hydrate). Iron-free aluminum sulfate for paint is usually used as a flocculant, used in the purification of drinking water and sewage treatment equipment, and also used in the paper industry. Health hazards: It has a certain stimulating effect on eyes and mucous membranes. Ingesting a large amount of paint with iron-free aluminum sulfate has a stimulating effect on the mouth and stomach. Explosion hazard: The product is non-flammable and irritating.

 

White polyaluminum chloride is a white or milky white milk powder fine powder formed by aluminum hydroxide powder and high-purity hydrochloric acid through spray drying, and it is easy to melt in the air. : First, the content of AL2O3 is high, 29.5% Second, the basicity is low, only 50%, and the basicity of ordinary polyaluminum is about 90% Third, the water-insoluble matter is small, only 0.3%, and ordinary polyaluminum has 2 %the above. Fourth, the color is pure, after the product is water, the aqueous solution is clear and transparent, without any color, and the color of the ordinary polyaluminum aqueous solution is yellow or brown.

How to Check the Purity of Iron Free Aluminum Sulfate for Medicine

Many customers have doubts about the production and release of iron free aluminum sulfate for medical use. What is the purity of the purchased product? Is the label on the packaging accurate? This series of problems are closely related to pharmaceutical iron free aluminum sulfate manufacturers. However, during the long-term transportation and storage of pharmaceuticals, there may be a slight qualitative change that affects the ingredients.

 

Take a small amount of sample and divide it into two parts. 1. Take one part to test tube 1. Add a sufficient amount of NaOH (aq) drop by drop. If the solution shows a white precipitate, and then the precipitate disappears, it means Al3 + 2. Take another one. As for the test tube 2, a small amount of Ba (NO3) 2 (aq) was added dropwise, and a white precipitate appeared, and then HNO3 (aq) was added dropwise, the precipitate did not dissolve. The medical iron free aluminum sulfate manufacturer introduced SO4 2 when it encountered such a display. + Exists. To the NaOH solution gradually, a white precipitate Al (OH) 3 is produced first. As the amount of NaOH increases, the precipitate gradually disappears to form NaAlO2 dissolved in water, which proves that Al ion takes the original solution. Dilute hydrochloric acid acidified BaCl2 solution was added dropwise (acidification with dilute hydrochloric acid is to eliminate the interference of Ag ion, sulfite ion, carbonate ion, etc.). If a white precipitate insoluble in dilute nitric acid is produced, it proves that there is sulfate ion.

 

Introduction to the Basic Knowledge of Medicinal Iron Free Aluminum Sulfate
 

We all know that iron free aluminum sulfate can be used as a medicament. Let's take a closer look.The iron free aluminum sulfate for medicine is used as an industrial agent. In its application, the iron free aluminum sulfate can dissolve the fine particles and natural colloidal particles in water into large flocs after being dissolved in water, so it is removed from the water. Aluminum can be used as coagulant for water supply and wastewater. Iron free aluminum sulfate is a widely used industrial reagent. Under natural conditions, iron free aluminum sulfate hardly exists in the form of anhydrous salts. It will form a series of hydrates. Iron free aluminum sulfate for medicine is also a very effective mollusc insecticide, which can kill spanish slugs. Medical iron free aluminum sulfate is used for water purification and as a medium in the printing and dyeing of textiles. In the purification of water, it causes impurities to condense, making it easier to precipitate and filter. When dissolved in a large amount of neutral or slightly alkaline water, colloidal aluminum hydroxide, al (oh) 3, is produced.

 

Increasing the temperature can improve the dissolving capacity of the liquid. Similarly, the low temperature in winter will also affect the dissolution effect of medical iron free aluminum sulfate as a coagulant in the sewage tank, especially in the northern regions, the water temperature in winter can reach minus zero. Water temperature is very important in many factors that affect the effect of sewage water treatment in winter. We know that iron free aluminum sulfate for medicine should be dissolved at room temperature. The dissolution rate is 5% -10%. Low temperature affects the rate of hydrolysis of the coagulant greatly. Low water temperature slows down the hydrolysis reaction. To solve this problem, we can appropriately increase the water temperature when configuring the iron free aluminum sulfate solution for medicine, and appropriately increase the water temperature of the sewage that needs to be treated, and try to abide by the principle of adding a small amount and multiple times.
