Spray droplet particle size: the precise lifeline of industry applications

In many industries that rely on spray technology, droplet size is not just a minor detail, but a core parameter that determines effectiveness and efficiency. Accurately measuring and controlling this core parameter directly affects application results and costs:

1. Agricultural plant protection

Pesticide spraying requires precise control of particle size (100-150 microns is preferred). Too large a particle size will cause the liquid to drift and pollute, while too small a particle size will cause evaporation and ineffectiveness. Optimizing the particle size can increase the deposition rate by more than 30%, reduce the amount of pesticides used, and reduce environmental risks.

2. Medical and health

Inhaled drugs require that the droplet size is strictly within the range of 1-5 microns, otherwise they cannot reach the deep lungs. Disinfectant spray requires a particle size of 50-100 microns to ensure suspension coverage. Particle size deviation will directly weaken the sterilization effect.

3. Industrial manufacturing

Automobile spraying relies on uniform droplets of 10-50 microns. Too large droplets will cause sagging defects, and too small droplets will cause dust pollution. In the flue gas desulfurization process, a 5% deviation in the absorption droplet size can lead to a 15% decrease in purification efficiency and a significant increase in energy consumption.

The key to increasing efficiency and reducing costs

Accurately testing the droplet size (such as laser diffraction) and dynamically controlling it has become the core means to optimize spray efficiency and ensure product quality. Ignoring particle size control is equivalent to allowing resources to be wasted and the effect to be out of control.

Therefore, it is very important to detect the particle size of spray droplet, which is one of the functions of the spray laser particle size analyzer. A high-performance laser particle size analyzer has the advantages of easy operation, fast test speed, good repeatability and accuracy. This time, Winner319 is recommended to test the particle size distribution of spray droplet powder for customers.

The measurement Range of Winner319 is 1-20000μm.(Can be extended to 0.1μm) It is mainly used to measure the particle size of liquid spray or mist powder. It can measure particle size of droplets, liquid droplets, smoke, aerosol, powder mist, etc. dispersed in the air without contact.

Measuring instrument information is as follows:
