  200 * 4 environmental protection insulation and high temperature resistance Guide chute coal curtain dust curtain rubber dust curtain for Crusher Wear resistance, corrosion resistance and high temperature resistance
I ordered a toy for my nephew online
It is estimated that the express delivery is busy at the end of the year
The toy hasn't arrived for several days
My nephew pestered me and asked: & ldquo; Uncle, did you buy it or not& rdquo; I said: & ldquo; Yes, I think it's blocked on the road& rdquo; My nephew grabbed my cell phone and said, & ldquo; Then tell Uncle express to let them call the police car
It's very fast& rdquo; I was shocked and thought I had to dare to accept the express

1、 Principle and function of dust curtain
Dust reduction principle of dust curtain: the dust curtain has the following functions: blocking and filtering: because the dust curtain is suspended in the roadway, the coal dust carried in the air flow is blocked and captured by the dust curtain when passing through the dust curtain, so as to reduce the concentration of coal dust in the air flow and purify the air flow
It has the functions of wetting and flushing: since the purification spray device is installed in front of the dust curtain, the coal dust captured by the dust curtain is wetted by the water drops of the purification spray, and flushed to the roadway floor, becoming the deposited coal dust that will never float

2、 Characteristics of dust curtain
It also has wear resistance , It has the characteristics of corrosion resistance, softness and good toughness
Especially in northern winter, it is not hard, does not crack and has a long service life
EPDM has excellent weather resistance
Weather resistance refers to the ability to resist severe cold, hot, dry and humid for a long time
It has excellent corrosion resistance to the erosion of rain, snow and water
It can completely prolong the service life of the adhesive strip
Heat aging resistance refers to strong heat-resistant air aging resistance
It can be used at 100-120 ℃ for a long time, and can maintain effective physical properties at 140-150 ℃ for a long time
It can withstand 230-260 ℃ high temperature in a short time, which can delay the occurrence of sudden accidents in urban buildings; In addition, with the use of special formula, EPDM feels similar at - 50 ℃ to 150 ℃, which creates high-efficiency work performance for production site installation
Because EPDM has ozone resistance, it is also known as & ldquo; Crack free rubber;, Especially when applied to various urban buildings with different atmospheric indexes and completely exposed to the air, it will show its superior quality
