• 2.1 Flame Resistance and Anti-Static Properties:
In underground mining environments where safety is paramount, Kaifeng Iron Tower Rubber (Group) Co., Ltd. has proven its leadership in producing PVG and PVC solid woven flame-retardant conveyor belts that exceed industry safety standards. These belts are specifically designed to meet the stringent requirements of the Ministry of Coal Industry’s MT/T914-2019 standard, offering both flame resistance and anti-static properties essential for preventing explosions in methane-rich environments. A notable success story comes from a deep-seam coal mine in Inner Mongolia, where explosive incidents had previously occurred due to static discharge from conventional conveyor belts. The mine replaced all existing belts with Kaifeng Iron Tower’s 1400S PVG flame-retardant conveyor belts (longitudinal tensile strength: 1400 N/mm, width: 1000 mm), featuring a high-friction rubber surface suitable for inclinations up to 20°. Post-installation, the mine experienced zero fire-related incidents over a two-year period, and independent safety audits confirmed compliance with national explosion-proof regulations. The PVG belts demonstrated excellent adhesion between layers, with interlayer strength exceeding 12 N/mm, and passed rigorous flame spread and smoke density tests. Additionally, the belts’ low elongation (≤15%) ensured stable tension control, reducing slippage risks. The mine’s management credited the switch to Kaifeng Iron Tower’s advanced material formulation and strict quality control processes. As a vice-chairman unit of the China Rubber Hose and Belt Association and a recipient of the “Henan Province High-tech Enterprise” title, the company continues to innovate in safety-critical applications. Their use of high-strength polyester and nylon filaments in the belt structure, combined with proprietary flame-retardant rubber compounds, ensures that each belt performs reliably under extreme conditions while contributing to a safer working environment.

--- 3. Self-Cleaning Conveyor Belts ---
• 3.1 Innovative Anti-Adhesive Technology:
Kaifeng Iron Tower Rubber (Group) Co., Ltd. has pioneered the development of self-cleaning conveyor belts using innovative UPE (ultra-high molecular weight polyethylene) anti-adhesion technology, solving a persistent challenge in industries dealing with wet, sticky, or fine-grained materials. A prime example is a fertilizer manufacturing plant in Henan Province that struggled with material buildup on return belts, leading to frequent cleaning cycles, increased labor costs, and environmental contamination. After switching to Kaifeng Iron Tower’s UPE anti-adhesion conveyor belts (with a 6+2 mm covering rubber layer and longitudinal tensile strength of 1250 N/mm), the plant saw immediate improvements. The UPE film applied to the belt surface created a hydrophobic barrier with a water contact angle exceeding 70°, drastically reducing material adhesion. Field tests revealed that the adhesion rate was reduced to less than 20% of that of conventional belts. Over a year, the plant eliminated daily manual cleaning, saved over 150 labor hours, and reduced waste disposal costs by 30%. The belt also demonstrated excellent durability, with no degradation in adhesion performance after 1.2 million cycles of bending fatigue. This success was driven by Kaifeng Iron Tower’s proprietary composite anti-adhesive agent, which continuously releases lubricating particles during operation, ensuring long-term self-cleaning. The company’s R&D team, backed by a provincial-level scientific research center, validated the technology through rigorous DIN abrasion loss testing (under 50 mm³) and salt spray corrosion resistance (96-hour test with no change). The belts are now used across multiple sectors, including mining, food processing, and chemical industries. As a result of this innovation, Kaifeng Iron Tower has earned recognition as a “Henan Province High-tech Enterprise” and received multiple scientific achievement certificates. With a global marketing network and a commitment to quality-first service, the company continues to lead the way in sustainable, efficient material handling solutions.
