Water based aluminum pigment. Alias: Water based aluminum powder; Water resistant aluminum powder. Property: A powder with a silver metallic luster in appearance, possessing the basic properties of aluminum pigment. It has a protective film on the surface of aluminum particles that can prevent direct contact between aluminum and water, and has good water resistance. Usage: Used as a metallic glitter paint in water-based coating systems, as well as in water-based inks, water-based leather decorative agents, etc

Aluminum pigment is added to alcohol solvents or alcohol ether solvents to prepare aluminum pigment slurry; Dissolve passivator and corrosion inhibitor in a second alcohol solution or second alcohol ether solvent to prepare an auxiliary solution, with a weight ratio of 1-5:1-5:40-100 between passivator, corrosion inhibitor, and second alcohol solution or second alcohol ether solvent; Add the additive solution to the aluminum pigment slurry to obtain an aqueous aluminum pigment solution, wherein the weight ratio of the additive solution to the PVD aluminum pigment slurry is 1:5-30; Separate the aqueous PVD aluminum pigment solution into solid and liquid phases, and obtain the solid phase material; Add solid phase substances to a third alcohol ether solvent to prepare water-based aluminum pigments.

1. Form of dispersion head (batch and continuous) (continuous is better than batch)

2. Shear rate of dispersing head (the higher, the better the effect)

3 dispersed head tooth structure (divided into initial teeth, middle teeth, fine teeth, ultra-fine teeth, with fine teeth having better effect)

4. The residence time of materials in the dispersed wall and the emulsification dispersion time (can be regarded as the same motor, the smaller the flow rate, the better the effect)

5 cycles (the more, the better the effect, and by the end of the device's lifespan, it cannot be any better)

Calculation of linear velocity

The definition of shear rate is the relative velocity of the liquid layer between two surfaces.

- Shear rate (s-1)=v rate (m/s)
G distance between stator and rotor (m)

As can be seen from the above, the shear rate depends on the following factors:

- Linear velocity of the rotor

In this case, the distance between the two surfaces is the rotor stator spacing.
The spacing range between SID stator and rotor is 0.2~0.4 mm

Speed V=3.14 X D (rotor diameter) X rotational speed RPM/60

High rotational speed and shear rate are crucial for obtaining ultrafine suspensions. According to some industry specific requirements, Xide Company has developed the XRS2000 ultra high speed shearing emulsifier machine based on the XR2000 series. Its shear rate can exceed 20000 rpm, and the rotor speed can reach 66m/s. Within this speed range, turbulence caused by shear forces combined with specially developed motors can reduce the particle size range to the nanometer level. The shear force is stronger, and the particle size distribution of lotion is narrower. Due to its extremely high energy density, it does not require any additional dispersing equipment and can achieve particle size at a pressure of 400 BAR, which is comparable to that of a regular high-pressure homogenizer

2. Equipment features

Compared to traditional devices:

Efficient and energy-saving

Traditional equipment requires 8 hours of dispersion processing, while XRS equipment takes about 1 hour to complete, resulting in significant ultrafine dispersion effect and reduced energy consumption;

High speed, high quality

The stirring speed of traditional equipment is several tens of revolutions per minute, while the speed with dispersion function is within 1500 revolutions per minute, which only completes macroscopic dispersion processing and has extremely limited ultrafine dispersion ability; The rotational speed of XRS equipment is between 10000 and 15000 revolutions per minute, and the shear force generated by ultra-high linear velocity instantly disperses the powder in the slurry.

Compared to similar devices:

Multi layer multi-directional shear dispersion

The structure of components such as the stator and rotor of similar equipment is single, and the multi-level and multi-layer structure is simply repetitive processing. The same tooth groove structure is prone to short circuits caused by raw materials passing through the working chamber without dispersion;

The fixed rotor structure of XRS equipment adopts the concept of multi-layer multi-directional shear, and the assembled structure allows materials to be sheared and dispersed in different directions, eliminating short circuits and achieving more thorough ultrafine dispersion.

The three-stage high shear dispersion machine is mainly used for the production of micro lotion and ultra-fine suspension lotion. Since three groups of dispersion heads (stator+rotor) in the working chamber work at the same time, after high shearing, the lotion drops are more delicate and the particle size distribution is narrower, so the stability of the generated mixed liquid is better. The three sets of dispersing heads are easy to replace and suitable for different process applications. The different models of machines in this series have the same line speed and shear rate, making it very easy to scale up production. It also meets the CIP/SIP cleaning standards and is suitable for food and pharmaceutical production.
