Powder Vibrating Sieve

The powder vibrating screen uses a motor to drive the vibration of the sieve mesh, causing the powder to move on the sieve surface. Fine particles pass through the sieve holes for separation, while coarse particles remain on the sieve surface. It is used for powder particle size classification and impurity removal, and is applied in quality control in industries such as coatings and plastics.
Selection
When selecting a powder vibrating sieve, considerations should include powder characteristics such as particle size and moisture content, requirements for sieving precision, corrosion resistance of the screen material, matching processing capacity with equipment size, adaptability of vibration methods to material properties, and ease of operation and maintenance.

High-temperature viscometer measures the flow behavior of powder coatings in the molten state.
This article introduces the use of a high-temperature viscometer to measure the flow behavior of powder coatings in their molten state. Powder coatings need to melt and flow before curing, a process that directly affects the smoothness and performance of the coating.
Hall flowmeter measures the flowability of spray powder
This article introduces how a Hall flowmeter measures the flowability of spray powder. It uses a standard funnel to measure the time required for a certain mass of powder to flow out under gravity—the shorter the time, the better the flowability.
Tap density tester evaluates the accumulation characteristics of sprayed powder.
This article introduces how to use a tap density tester to evaluate the packing characteristics of spray powders. The tap density tester simulates vibration to densely pack the powder and measures the mass per unit volume, thereby obtaining the tap density.
Laser particle size analyzer measures the particle size distribution of spray powder.
Laser particle size analyzers measure the particle size distribution of sprayed powder based on the principle of light scattering, which is critical for coating uniformity and adhesion. During measurement, the powder must be dispersed in a suitable medium to avoid agglomeration, and tests should be repeated to ensure accuracy.
Sand Falling Test Apparatus for Measuring the Wear Resistance of Powder Coatings
The sand falling test instrument determines the wear resistance of powder coatings by simulating sand particle impact. During the test, abrasive material falls vertically from a specified height, continuously scouring the coating until the substrate is exposed. The wear resistance is evaluated based on the mass of abrasive material consumed.
Impact testing machine tests the impact resistance of powder coatings.
This article introduces the method of testing the impact resistance of powder coatings using an impact tester. The test simulates instantaneous impact through a falling weight or pendulum hammer, following ISO or ASTM standards.
Pendulum hardness tester measures the damping hardness of powder coatings.
This article introduces the method of testing the damping hardness of powder coatings using a pendulum hardness tester. The test is based on the principle of energy attenuation, where the hardness is reflected by the time it takes for the amplitude of the pendulum to decay as it swings on the coating surface, with a longer time indicating a harder coating.
Karl Fischer Moisture Analyzer Determines Moisture Content in Powder Coatings
This article introduces the method of determining the moisture content in powder coatings using a Karl Fischer moisture analyzer. Excessive moisture content in powder coatings can affect the quality of the coating, leading to issues such as bubbles. The Karl Fischer method measures moisture through the quantitative reaction of iodine and sulfur dioxide, which is divided into volumetric and coulometric methods.
Density Determination: Selection Strategy between Pycnometer Method and Densimeter Method
This article introduces two methods for measuring the density of substances: the pycnometer method and the densimeter method. The pycnometer method calculates density by measuring the mass of a sample of fixed volume. It is suitable for measuring liquids, powders, and small granular solids, offering high precision but slower operation, and requires temperature control.
Salt spray test chamber evaluates the protective performance of powder coatings
The salt spray test chamber accelerates the evaluation of the corrosion resistance of powder coatings by simulating a salty and humid environment. The test is based on electrochemical principles, where salt spray penetrates coating defects and initiates corrosion of the metal substrate. During operation, parameters such as temperature and sedimentation rate must be strictly controlled, and standards such as ISO and ASTM must be followed.
