Aluminum stearate appears as a white powder. Insoluble in water, soluble in ethanol, benzene, turpentine, mineral oil, and alkali. Heating or contact with strong acid decomposes into stearic acid and corresponding aluminum salts.

Main purpose
This product is widely used as a non-toxic heat stabilizer for polyvinyl chloride, a metal rust inhibitor, a waterproofing agent for building materials, an emulsifier for cosmetics, a thickener for coatings and inks, a lubricant for plastic products, and a defoamer for petroleum drilling.

SID three-stage high shear emulsifier stator and rotor configuration: 2G 6F 8SF, imported from Germany with ultra-high precision, stator and rotor clearance of 0.2-0.3mm (domestic stator and rotor clearance is generally 0.5-1mm)
experiment:
1. The SID three-stage high shear emulsifier is turned on and running at a speed of 18000rpm. Slowly add 1.5kg of thick solution, turn on the mixer at a speed of 600rpm (to ensure that the material passes evenly through the working chamber and is uniformly sheared), and after running for 30 minutes, sample, discharge, and test the material.
2. The SID three-stage high shear emulsifier is turned on and running at a speed of 18000rpm. Slowly add 1.5kg of dilute solution, turn on the mixer at a speed of 800rpm (to ensure that the material passes evenly through the working chamber and is uniformly sheared), and after running for 30 minutes, sample, discharge, and test the material.
Experimental effect: The material has excellent emulsification and homogenization effect, and the particle size reaches the ideal size, which meets the customer's requirements for using the material on coating.

Introduction to calcium stearate:
Appearance: White powder, insoluble in water, soluble in organic solvents such as hot benzene, benzene, and turpentine. When heated to 400 ℃, it slowly decomposes and is flammable. When exposed to strong acids, it decomposes into stearic acid and corresponding calcium salts, and has hygroscopicity.
Usage description:Stabilizer; lubricant; Paint leveling agent; Lubricant for pencil lead; Plastic release agent; Building waterproofing agent; Thickener for lubricating oil, halogen absorbent for polypropylene and polyethylene
purpose：Used as a heat stabilizer for polyvinyl chloride and a lubricant for various plastic processing, release agent, etc. In hard products, the gel speed can be improved by combining with basic lead salt and lead soap. It is also used for food packaging, medical equipment, and other soft films and devices that require non-toxic properties. It can also be used as a halogen absorbent for polyethylene and polypropylene to eliminate the adverse effects of residual catalysts on color and stability. stayrubberAs a plasticizer during processing, it can soften natural rubber and synthetic rubber, while having almost no effect on vulcanization. Also used as polyolefin fibers andMold plasticLubricants, thickening agents for lubricating grease, waterproofing agents for textiles,paintFlattening agents, plasticizers used in the production of plastic records, etc. It is also used in pencil lead production, as well as in the pharmaceutical and spice industries.

Working principle of SID three-level high shear emulsifier:
A three-stage emulsifier is the process of efficiently, quickly, and uniformly transferring one or more phases (liquid, solid, gas) into another immiscible continuous phase (usually liquid). Under normal circumstances, each phase is immiscible with each other. When external energy is input, the two materials recombine into a homogeneous phase. Due to the strong kinetic energy brought by the high tangent speed and high-frequency mechanical effect generated by the high-speed rotation of the rotor, the materials are subjected to strong mechanical and hydraulic shearing, centrifugal extrusion, liquid layer friction, impact tear and turbulence in the narrow gap between the stator and rotor, forming suspension (solid/liquid), lotion (liquid/liquid) and foam (gas/liquid). Thus, the immiscible solid, liquid, and gas phases can be dispersed and emulsified uniformly and finely in an instant under the combined action of corresponding mature processes and appropriate additives. After high-frequency cycling, stable high-quality products are finally obtained.
The purpose of SID three-level high shear emulsifier
The three-stage emulsification machine is mainly used to process a large number of lotion and generate ultra-fine suspension lotion. Due to the simultaneous use of three working heads (rotor and stator) for processing, a very narrow particle size distribution can be obtained, resulting in smaller droplets and particles, and thus better stability of the generated mixture. The dispersing head is easy to replace and suitable for various applications. Different machines have the same rotational speed and shear rate, which facilitates scale expansion. Compliant with CIP and SIP cleaning standards, therefore sanitary grade is particularly suitable for food and pharmaceutical production.
Characteristics of SID three-level high shear emulsifier:
The XR2000 series three-stage emulsifier has very high shear speed and shear force, with a particle size of about 0.2-2 microns to ensure the stability of high-speed dispersion emulsification. This device can be applied to various dispersion emulsification processes, as well as for the production of homogeneous mixtures including emulsions, suspensions, and colloids. The shear force generated by the fixed/rotor system in the three-stage emulsifier increases the solute transfer rate, thereby accelerating the decomposition of single molecules and macroscopic molecular media.

The agglomeration of nano powder refers to the phenomenon that the original nano powder particles are interconnected and form large particle clusters from multiple particles in the process of preparation, separation, treatment and storage. Due to the small particle size, high surface atomic ratio, large specific surface area, and high surface energy of agglomerated particles, they are in an energy unstable state. Therefore, fine particles tend to aggregate together and easily form agglomerated secondary particles, even tertiary particles, which increase the particle size and have small pores inside each particle.
The aggregation of nanoparticles is generally divided into two types: soft aggregation and hard aggregation. For the mechanism of soft agglomeration, people have a more consistent view, that is, soft agglomeration is caused by van der Waals force and electrostatic attraction between molecules or atoms on the surface of nano powder. Because the force is weak, it can be eliminated by some chemical action or mechanical energy.

Grinding and dispersing machine is a high-tech product composed of colloid grinding and dispersing machines.

The first level consists of three-level sawtooth protrusions and grooves with increasing precision. The stator can be infinitely adjusted to the desired distance between the rotors. Under enhanced fluid turbulence. The groove can change direction at each level.
The second stage is composed of a stator. The design of the dispersing head also effectively meets the needs of substances with different viscosities and particle sizes. The difference in the design of the stator and rotor (emulsifying head) between online and batch machines is mainly due to the requirements for conveying performance. It is particularly important to note that the difference between coarse precision, medium precision, fine precision, and other types of working heads is not only the arrangement of specified rotor teeth, but also an important difference in the geometric characteristics of different working heads. The width of the slot and other geometric features can alter the different functions of the stator and rotor working heads.
