The glow wire test is to test the stability of electronic and electrical products at work. The glow wire itself is actually a fixed-size resistance wire ring. During the test, it is heated to the specified temperature with electricity, so that the tip of the glow wire contacts the sample to reach the standard required time, and then observe and measure its state. The test range depends on the spec...
Melt-blown non-woven fabrics are widely used in the field of filter materials, and can be described as the “heart” of the mask structure. The average fiber diameter of polypropylene melt-blown fabrics is 2 to 5 μm, and the droplets with a particle size of more than 5 μm in the air can be blocked. But can only block less than 70% of the particles. Even if the barrier rate is increas...
