G·FORCE® Anti-impact Ventilation Duct Advantages:
Chengdu Foresight Composite Co., Ltd., the biggest mining ventilation duct fabric manufacturer in China, cooperated with global security industry expert Dupont™ and combined our original antistatic, lamination and fire resistance technology to develop G· force® anti-explosion and anti-impact ventilation duct with Kevlar® fiber as skeleton.
Kevlar® is a high strength and high modulus synthetic fiber which developed by Dupont™ in 1995, its strength is 5 times higher than the same weight steel wire, and has advantages of excellent flexibility, fire resistance, chemical resistance, explosion resistance and cutting resistance, it has been wildly used for bulletproof product, explosion-proof airline baggage compartment, suspension bridge reinforced structure, fire proof suits and aerospace equipments etc.
5 new breakthroughs of G· FORCE® anti-impact ventilation duct :
1. Use high modulus Kevlar® fiber to increase the skeleton to get higher strength, more wearproof, and more high and cold temperature resistance, so the product performance has been improved greatly, and much better for harder rock driving work face.
2. New rubber and plastic coating process, prepareing textile fiber and thicken membrane more than 20% make the closely laminated of pvc membrane and fiber to be more anti-impact.
3. 50% increase of seam width for suspension rib to improve the anti-impact.
4. Special high modulus Kevlar® as sewing thread to avoid the risk of sewing thread breakage.
5. Original G·FORCE® anti-impact sealing flap extend to slove the problem pf metal ring fall out, ventilation breaking and ensure stanble and continuous air flow.
