Shandong Dongtai’s high-quality dust-proof curtains. To buy dust-proof curtains, look to Yanzhou Dongtai, which specializes in the production of dust-proof curtains.

&&Someone help, someone has fainted! &rAt around 9:00 a.m., a few meters away from the gate of Shengjing Hospital Affiliated to China Medical University, the 6-year-old Aunt Ding suddenly felt dizzy, her eyes blurred, and she lost control of her legs and feet. Then, Aunt Ding almost fell to the ground. . Soon after, a young man grabbed Aunt Ding and shouted for help.
Under the treatment of medical staff, Aunt Ding, who was diagnosed with cerebral infarction, was finally out of danger, but the young man quietly left the scene. Aunt Ding said: "I don't know this young man. I didn't even have time to ask his name. He saved my life." &rNow that Aunt Ding's health has improved, she wants to find this kind-hearted young man and say thank you to him in person.
>The dust curtain has the following functions
>
The dust curtain has the following functions: blocking and filtering: & Since the dust curtain is hung in the tunnel, the dust carried in the wind flow When coal dust passes through the dust curtain, it is blocked and captured by the dust curtain, thereby reducing the concentration of coal dust in the air flow and purifying the air flow.
Has moistening and flushing effects: &Since a purification spray device is installed in front of the dust curtain, the coal dust captured by the dust curtain is moistened by the water droplets of the purification spray, and flushed to the tunnel floor, becoming Deposited coal dust that never floats
>.& Composition of dust curtain:
& Dust curtain consists of purification spray and dust curtain. The purification spray should be able to seal the entire section of the tunnel. The installed dust curtain The distance between the air inlet side of the curtain and the dust curtain should not be less than .
The dust curtain is made of materials with good air permeability, and its shape can be the same as the tunnel section
>.& Installation of dust curtain:
& The dust curtain is installed along the roof of the tunnel, The size of the dust curtain is basically consistent with the specifications of the tunnel. A relatively heavy iron or wooden stick is installed at the lower part of the dust curtain to make the dust curtain droop and seal the entire section of the tunnel.
Since the structure of the guide trough is the main factor affecting the dust removal effect, the factors include the length of the guide trough, the size of the flow cross-section at the entrance and exit, etc. Therefore, these main factors have become the main content of experimental research on improving the dust removal effect of the guide trough.
The dust removal effect of the guide trough is poor. Analysis of the main reasons is that the dust-proof structure is not complete enough, and the flow area at the outlet of the guide chute is too large (the outlet is close to an open type), and dust can be freely spread out without resistance. In response to existing problems, measures were taken to install double/multi-layer soft dust curtains at the exit of the guide trough. After the implementation of the measures, the dust removal efficiency of the guide trough has been significantly improved. The guide trough can effectively control the free spread of dust and greatly reduce the mass concentration of dust in the coal conveying trestle.
The EPDM used in dust-proof curtains has excellent weather resistance. Weather resistance refers to the ability to withstand severe cold, heat, dryness, and moisture for a long time, and has excellent corrosion resistance against the erosion of rain, snow, and water. It can completely extend the service life of the rubber strip. Heat aging resistance refers to its strong resistance to hot air aging.
Due to the high-quality material selection, the dust-proof curtain can be used at ℃ for a long time. It can also maintain effective physical properties at ℃ for a long period of time. It can withstand high temperatures of ℃ in a short time and is suitable for urban buildings in sudden accidents. , can play a delaying role and using a special formula, EPDM rubber has a similar feel at ℃ to ℃, which creates high-efficiency work performance for production site installation. Because EPDM has excellent ozone resistance, Also known as "crack-free rubber", it is especially used on various urban buildings with different atmospheric indexes and completely exposed to the air, which will show its superior quality
