JULI® Mining Layflat Ventilation Duct Advantages:
1. Since 2006, Foresight has more than 10 years experience of manufacturing ventilation duct and ventilation duct fabric, and owns a strong R&D team which consists of over 10 engineers graduated from professional school, exceeds 30 high-speed rapier looms, 3 laminated production lines, several automatic production lines for pvc ventilation duct, which ensures annual production of rolled film over 10,000 tons, pvc ventilation duct fabric 15,000,000 square meters, pvc ventilation duct 2,000,000 meters. Foresight continues to supply the all kinds of ventilation ducts for coal mines at home and abroad.
2. Compared with traditional ducts like rubber, glass fiber and plastic dip, JULI® pvc ventilation duct has advantages of lighter weight, thinner material, higher strength duct, more convenient installation, maintainance and repairaton. Composite cost will be decreased more than 25%.
3. Foresight original carbon black surface treatment antistatic technology has won Safety Production Science and Technology Achievement Award issued jointly by SAWS and SACSS. It keep antistatic value <3*108 after two years application.
Now a new environmental friendly water soluble mateial without volatie component has been developed, which doesn't exhaust VOC during production, and stablish the antistatic value about 3*106, and 3*108 can be met totally.
4. Automatic layflat ventilation duct production line researched and developed by ourselves has made standardization, automation and large scale production come true, and completely avoided the quality variation due to employee turnover caused unstable hand processing and technical differences, released the process cutting material and welding suspension rib, it can welding the material to form and fold the duct automatically, so the working efficiency will be increased 3 times, and the welding tensile will be improved 20%.
5. Customized overlength duct for coal mine is available,and the composite cost will decreased 15%. Foresight explored a new duct solution with overlength distance air supply, a little joint, low resistance, and low cost from technology and cost. Customized 20-100m or even more section length is available.
