AI Technical Summary

Technical Problem

In existing chemical fiber combustion performance testing devices, there are deviations in the detection of droplet behavior, especially in the vertical combustion method where the concentrated droplets fall and overlap, making it difficult to accurately measure the number of drops and the mass of each drop.

Method used

The servo motor-driven rotating rod and sampling cylinder work in conjunction with the sampling disk. The spiral groove design ensures that the molten droplets are evenly distributed. The servo motor drives the rotating rod to rotate and the sampling cylinder to move horizontally, ensuring that the molten droplets are independently distributed on the sampling disk, reducing overlap and collision.

Benefits of technology

It achieves uniform distribution of molten droplets, accurately detects the number of droplets and the mass of each droplet, reduces detection deviation, and improves the accuracy of combustion performance testing.
