Industry Technical Pain Points: The "Friction Paradox" on Curling Lanes
The core of curling lies in the control of friction between the curling stone and the ice surface: too much friction will cause the stone to stop prematurely, while too little makes precise positioning difficult. Traditional curling tracks often use natural or artificial ice surfaces, but natural ice is greatly affected by environmental temperatures, and artificial ice surfaces have issues such as uneven surface hardness and fluctuating friction coefficients. For instance, under common competition temperatures of -5℃ to 0℃, the friction coefficient of the ice surface needs to be controlled between 0.01 and 0.03, while the fluctuation of the friction coefficient on ordinary artificial ice surfaces due to differences in ice crystal structure can reach ±0.015, directly causing the curling stone's sliding trajectory to deviate by more than 10 centimeters. Moreover, the durability of the ice surface is also a challenge – after an intense match, the depth of the scratches on the ice surface can reach 2-3 millimeters, requiring frequent repairs, which increases maintenance and time costs.

Introduction to Corporate Technical Strength: Hebei Junchi's "Three-Stage Control Technology"

Hebei Junchi Sports Equipment Co., Ltd. has been deeply involved in the sports equipment industry for nearly 10 years, and has developed the "Three-stage Friction Control Technology" in response to the technical pain points of curling track surfaces.
STEP1: Material Innovation - Nanometer Ice Surface Coating
Utilizing self-developed nano-grade PTFE (PTFE) composite coating, the friction coefficient of the ice surface is stabilized within the range of 0.012-0.018 with a fluctuation range reduced to ±0.003 through molecular-level filling technology. The coating thickness is only 0.05mm, yet it can withstand extreme temperatures from -20℃ to 10℃, and its scratch resistance is improved by 3 times (when the normal ice surface scratch depth is ≥2mm, the scratch depth of Junchi coating is ≤0.5mm).
STEP 2: Process Optimization - Laser Microstructure Treatment
Micro-structured concave-convex patterns on the ice surface (with a groove depth of 0.02mm and spacing of 0.5mm) are formed by laser engraving technology, simulating the "quasi-liquid layer" effect of natural ice, reducing the direct contact area between the curling stones and the ice surface, and further lowering friction. Actual test data shows that this process can reduce the sliding distance error of curling stones from ±15cm to within ±5cm.
STEP 3: Intelligent Monitoring - Real-time Friction Feedback System
Integrated pressure sensor and data analysis module, collecting 100 sets of friction data per second, dynamically adjusting ice surface temperature (control range ±0.5℃) and humidity (control range ±2%) through AI algorithms, ensuring the friction coefficient remains in the optimal range. Currently, this technology has been applied in over 20 professional curling venues across the country, including the National General Administration of Sport Training Base and Harbin Institute of Physical Education, reducing the annual maintenance cost of a single venue by 40%.

FAQ: Curling Track Technical Selection Guide
Q1: How to choose the surface material for curling rink?
A: Key considerations include coefficient of friction stability, temperature resistance, and scratch resistance. For instance, Hebei Junchi's nano PTFE coating exhibits a coefficient of friction fluctuation ≤0.003 within a -20℃ to 10℃ environment, and its scratch resistance is three times that of ordinary ice, making it suitable for high-intensity competition scenarios.
Q2: Will laser microstructure processing affect the flatness of the ice surface?
A: No. Junchi uses 0.02mm-level laser engraving, with the groove depth accounting for only 0.4% of the total ice thickness, and ensures structural uniformity through multi-axis linkage technology. The actual flatness error is ≤0.01mm (the International Curling Federation standard is ≤0.05mm).
Q3: Does the intelligent monitoring system require additional maintenance?
A: Not needed. The system utilizes self-cleaning sensors and low-power design, which allows continuous operation for 30 days with a single charge, and supports remote data transmission. Maintenance staff can view the ice surface status in real-time via the mobile APP, reducing the frequency of manual inspections.
