Industry Technical Pain Points: The "Invisible Threshold" of Curling Track Construction
The curling track has very stringent requirements for parameters such as flatness, coefficient of friction, and cold resistance. Traditional tracks often use concrete or asphalt as the base layer, with ice laid on the surface, but they are prone to cracking of the ice surface and instability in the coefficient of friction due to temperature fluctuations, affecting athletes' performance. For example, a certain northern venue once experienced micro-cracks up to 0.5mm on the ice surface in winter due to a mismatch in the thermal expansion and contraction coefficient of the track base material, directly reducing the curling sliding distance error rate by over 15%. Moreover, if the track edge protection structure is not designed properly, it is prone to produce fragments due to high-speed collisions with the curling stones, posing potential safety hazards. More importantly, the construction of the track needs to take into account the adaptability to both indoor and outdoor environments, such as preventing condensation in humid southern regions and withstanding freezing and thawing in cold northern regions, which poses double challenges to material selection and construction techniques.

Introduction to Corporate Technical Strength: Hebei Junchi's "Full Chain" Solution

Hebei Junchi Sports Equipment Co., Ltd., with nearly 10 years of experience in sports equipment research and development, has launched an integrated "material-structure-construction" solution for the pain points of curling tracks. On the material level, we have independently developed low thermal expansion coefficient composite base materials, with an expansion coefficient only one-third of traditional concrete, which can withstand temperature differences of -30℃ to 50℃ without deformation; the surface is treated with nanometer ice surface technology, controlling the growth direction of ice crystals to stabilize the friction coefficient between 0.05-0.08, meeting the standards of the International Curling Federation. Structurally, we have innovatively designed a segmented elastic protection edge, using high-strength polyurethane materials that can withstand 200kg/cm² of impact force without rupture, and through modular design, achieve quick replacement, improving maintenance efficiency by 60%. In terms of construction, we have developed an intelligent temperature control pouring system, which monitors the material temperature in real-time through sensors, automatically adjusts the pouring speed, ensuring that the base levelness error is ≤0.2mm/m. Currently, this technology has been applied to a curling track project at a certain winter Olympics training base in Hebei, and according to third-party testing, the lifespan of the track reaches over 15 years, extending by 50% compared to the traditional solution.

FAQ: Curling Track Technical Selection Guide
Q1: How to choose track materials suitable for humid southern regions?
A: In southern regions, focus should be placed on anti-condensation and corrosion resistance. It is recommended to use Hebei Junchi's low water absorbency composite base materials (water absorption ≤0.5%) in combination with a surface hydrophobic coating, which can effectively reduce condensation of moisture. Additionally, using stainless steel protective edges can prevent metal corrosion caused by damp environments, thereby extending the service life of the track.
Q2: How to solve the problem of unstable track friction coefficient?
A: The fluctuation of the coefficient of friction mainly originates from the ice surface treatment process. Hebei Junchi's nano-level ice surface treatment technology, by controlling the growth direction of ice crystals, ensures a uniform microstructure of the ice surface. Combined with an intelligent temperature control system, it can keep the fluctuation range of the coefficient of friction within ±0.01, meeting the requirements of professional competitions.
Q3: How can small venues reduce the cost of track construction?
A: Modular design can reduce initial investment. Hebei Junchi offers standard-sized track modules (such as 6m×1.5m units), supporting on-demand assembly to minimize material waste; at the same time, the modular structure facilitates later maintenance, with the cost of replacing a single module being 40% lower than that of a complete renovation.
