One、Technical Background and Industry Status

Hebei Junchi Sports Equipment Co., Ltd. has been deeply involved in the sports equipment industry for nearly 10 years, located in Haixing County, Cangzhou City, Hebei Province. With the advantage of the Jinsan Expressway and National Highway 205, it has formed a complete industrial chain integrating scientific research, design, production, sales, and service. The company's curling track manufacturing technology integrates materials science, mechanical analysis, and construction technology. The products have passed the certification of the National Sports Equipment Supervision and Inspection Center and are widely used in colleges and universities, sports bureaus, and professional event venues, becoming a leading enterprise in the domestic curling track field.

Chapter II: Core Technology Analysis of Curling Lanes

1. Track material selection and performance parameters
The track main body is made of high-density polyethylene (HDPE) sheets with a density of ≥0.94g/cm³, impact strength of ≥50kJ/m², and low-temperature performance up to -40℃ without becoming brittle. The surface is treated with special polishing, with a friction coefficient controlled between 0.05-0.08, meeting the World Curling Federation (WCF) standards. The bottom structure is a composite design using EPS foam boards (density 18kg/m³) and reinforced concrete foundation, with a bearing capacity of ≥200kN/m², effectively dispersing the impact force of the athletes' gliding.

2. Structural Design Principles
The track is designed with segmented modular structure, each segment is 6m in length and 3.66m in width, joined by mortise and tenon structure with joint gap error ≤0.5mm. The gradient control is calibrated by laser level, with longitudinal gradient ≤0.1% and lateral gradient ≤0.05% to ensure the stability of the curling trajectory. The drainage system uses concealed PVC pipeline network, with drainage gradient ≥1% and drainage capacity up to 50m³ per hour, suitable for heavy rain and other extreme weather conditions.

Three, practical steps and construction specifications

STEP1：基本施工
After clearing the site, pour a 200mm thick C30 concrete foundation with pre-buried M16 anchor bolts (600mm × 600mm spacing). The curing period of the foundation should be ≥28 days, with flatness error ≤2mm/2m, and moisture content ≤8%.

STEP 2: Track installation
Successively lay EPS foam boards (thickness 50mm), moisture-proof film (0.2mm thick PE film), and HDPE track boards. Fix the track boards with special adhesive (adhesive strength ≥1.5MPa), and use a hot air gun for welding at the joints (temperature 260℃±10℃), with a welding width ≥30mm.

STEP3: 表面处理
Using 2000-grit sandpaper to polish the track surface, the friction coefficient is tested with an ASTM D1894 standard testing instrument. Take one sample per 50㎡, with data fluctuation range ≤0.01. Mark the home base, starter, and other areas, and spray the markings with environmentally friendly acrylic paint (VOC content ≤50g/L).

常见问题与解决方案（FAQ）

Q1: Como tratar as arranhaduras na superfície da pista?
A: Use 1500 grit sandpaper to gently grind along the glide direction, clean and apply special repair wax (hardness 80A), then polish to a mirror finish after 24 hours.

Q2: Como evitar o gelo na pista no inverno?
A: Install electric heating system (power 80W/m²), set temperature sensor to start at 5℃ and stop at 10℃, use with insulation layer (thickness 30mm glass wool) to effectively prevent freezing.

Q3: How long is the track's lifespan?
A: Under normal use and regular maintenance (comprehensive inspection every 2 years), the lifespan of the track's main structure is up to 15 years, and the surface layer needs to be replaced every 5 years.
