Description of properties of aluminum stearate

White or yellowish powder, insoluble in water, ethanol and ether; dissolved in alkali solution and kerosene, decomposed into stearic acid and corresponding aluminum salt when meeting strong acid.

Purpose:

It is used as heat stabilizer of PVC, antirust agent of metal, waterproof agent of building materials, emulsifier of cosmetics, brightener and thickener of paint and ink, lubricant of plastic products, defoamer for oil drilling, etc.

Working principle of aluminum stearate dryer:

Air drying can quickly remove moisture (mainly surface moisture) from particles and powder materials which are easy to dehydrate. In air flow drying, due to the short residence time of materials in the dryer, the quality of the dried products is well controlled. The intensified airflow drying in our factory is composed of a set of intensifier with stepless speed adjustment on the basic model. The wet material enters the intensifier through the spiral feeder and is fully mixed with the hot air flow. Under the crushing and pushing of the rapidly rotating striking knife, the material is broken into fine particles and moves to the outlet at the same time. After that, it enters the drying tube under the attraction of wind power and further evenly dries. The wet weight particles which can not be attracted by the wind are broken and dried until they can be sucked into the drying pipe.

Main uses of aluminum stearate dryer
this machine is especially suitable for those with high moisture content, Wet materials are paste like materials that cannot be dried by other air drying methods, such as white carbon black, copolymers of vinyl acetate and vinyl chloride, cellulose acetate flocs, catalysts, C.M.C CT-1 resin, gypsum, electrolytic manganese dioxide, ammonium anthraquinone sulfonate, fluorspar, diatomite, silica gel catalyst, bone powder, high territory, potassium perchlorate sulfonate drugs, synthetic resin, active gluten, activated clay, chemical filter cake, rutile drilling white powder, sebacic acid, copper sulfate, aluminum sulfate, sodium sulfate, calcium phosphate, esterified starch, dye, calcium citrate Slime, bread with round surface, rice bran, clay, clay cement, urea, bentonite, spherical clay, aluminum hydroxide, barium hydroxide, calcium lactate, food, washing high territory, cyanuric acid, gypsum slurry, lime, biological products, carbon black, calcium carbonate slurry, sludge residue, organic chemicals aluminum stearate, iron oxide, organic fuel, corn protein feed, wet mud Mica powder, pharmaceutical, pigment, potassium dichromate pulp, distiller's grains residue, etc.
What are the reasons why the airflow dryer stops working?

1. Improper control of water evaporation and hot air temperature:
 air dryer has short drying time, dehydration occurs in 0.5-3 seconds, high thermal efficiency, no overheating, drying process is highly automated. The drying evaporation is from 25 kgho / h to 2000 kgho / h, and the temperature range of hot air is from 120 ℃ to 780 ℃; therefore, it is not suitable to continue the airflow drying operation when the water evaporation and hot air temperature exceed the above-mentioned parameter standards.to sum up, when the gas inlet temperature is constant and other conditions are normal, when the gas outlet temperature is high, slowly increase the speed of the feeder to increase the feed quantity and reduce the gas outlet temperature to the required temperature; on the contrary, when the gas outlet temperature is low, the moisture content of the dry product will be affected, so the rotation speed of the spiral feeder will be reduced, the feed rate will be reduced, and the gas outlet temperature will be increased Degrees to the required temperature.

2. Improper control of material particle size:
 some materials are very easy to adhere to the pipe wall, such as titanium dioxide, crude glucose, etc., it is not suitable to use the air drying method; in addition, because the particle size of the material is too fine or the material itself is toxic, the air drying method is generally not suitable for gas-solid separation. Because of the high air velocity, the particles are well dispersed in the gas phase. The total surface area of particles can be used as the effective area of drying. Therefore, the effective area of drying is greatly increased.
