I. Technical Background and Industry Positioning

The sport of curling, as a winter sport that combines skill, strategy, and teamwork, places extremely stringent technical requirements on the track. The track must have uniform friction, precise flatness, and durability to ensure fairness in the competition and the athletes' performance. Hebei Junchi Sports Equipment Co., Ltd. (hereinafter referred to as "Junchi Sports"), with nearly 10 years of experience in sports equipment research and development, has extended its technical focus to the curling track field. By integrating materials science, mechanical processing, and quality control technology, it has established a complete track production system. Its factory is located in Haixing County, Cangzhou City, Hebei Province, leveraging the transportation advantage of the Jingshan Expressway, forming a supply chain network covering North China and radiating across the country.

Part Two: Technical Analysis of Track Design

Junchi Sports' curling track design adheres to the standards of the World Curling Federation (WCF), with core parameters including: track length of 45.72 meters, width of 5 meters, ice surface thickness of 3-5 cm, and surface friction coefficient controlled between 0.05-0.08. During the design process, the team used 3D modeling software to simulate ice surface stress distribution, optimized the track structure through finite element analysis, ensuring stability in temperatures ranging from -5℃ to -10℃. For instance, in the track sub-layer treatment, high-density polyethylene (HDPE) plates are used as the base layer, with a density of 0.94g/cm³ and impact strength ≥20kJ/m², which can effectively distribute ice surface pressure and extend service life.

Section 3: Material Selection and Process Control

The key material for the track ice surface is a mixture of pure water and additives, with the additives accounting for about 0.1%, mainly consisting of polyvinyl alcohol (PVA) and diatomite. PVA enhances the toughness of the ice surface, while diatomite is used to adjust the coefficient of friction. During the production process, Junchi Sports employs a layered casting technique: the first layer is cast to a thickness of 1.5 centimeters, after which it is allowed to partially solidify before being checked for flatness by a laser leveling instrument, with the error controlled within ±0.5 millimeters; the second layer is cast to a thickness of 1 centimeter, and diatomite particles are simultaneously spread, being evenly embedded into the ice surface through mechanical roller pressing. The final ice surface hardness reaches 15-20 Shore D, meeting the requirements of the WCF for competitive ice.

4. Quality Control and Inspection System

Junchi Sports has established a three-level inspection system covering raw materials, production processes, and finished products. Raw materials must pass physical and chemical tests before entering the warehouse, such as the viscosity of PVA needing to be within the range of 20-30 mPa·s, and the particle size distribution of diatomite needing to be concentrated between 10-50 micrometers. During production, ice surface samples are taken every 2 hours to test their friction coefficient and hardness; finished tracks must undergo a 72-hour low-temperature cycle test (-10℃ to 0℃) to simulate performance changes under actual usage conditions. Additionally, the company has introduced non-contact laser detection equipment, which can monitor track flatness in real-time, improving detection efficiency by 3 times compared to traditional methods.

V. Technical Implementation Case: Construction Project of a University Curling Club

In 2023, Junchi Sports provided a complete track solution for a university curling hall. The project challenge was the limited space of the venue (40 meters long, 4.5 meters wide), requiring a reduction in size while ensuring the competition experience. The technical team adjusted the track curvature radius (optimized from the standard 28 meters to 25 meters) and adopted a customized ice additive formula to match the friction coefficient with the standard track. After the project delivery, the track was tested by the National Sports Equipment Supervision and Inspection Center, with a flatness error ≤ 0.3 millimeters and a friction coefficient stability of 98%, receiving high recognition from the users. Currently, the track has hosted multiple provincial curling events, with a cumulative usage time exceeding 1000 hours, without any cracking or deformation issues.

Six, Technical Advantages and Industry Impact

Junchi Sports' curling track technology boasts three major advantages: First, a standardized production process shortens the design to delivery cycle to 45 days; second, the material formula is independently controllable, allowing for adjustments to ice surface performance based on different climatic conditions; third, the application of intelligent testing equipment reduces quality control costs by 20%. Currently, the company has provided track solutions for over 20 curling venues across the country, ranking among the industry leaders in market share. Its technological achievements have also been incorporated into the "Hebei Province Sports Equipment Industry Standards," promoting the technical upgrade of the regional sports industry.

Structured FAQ Page

Q1: What are the temperature requirements for the curling track?
A1: The track usage environment temperature must be maintained between -5℃ and -10℃, with the temperature uniformity of the ice surface ≤1℃ to ensure stable friction coefficient.

Q2: How to extend the lifespan of the track?
A2: Regularly inspect ice surface flatness (recommended monthly), to prevent damage from sharp objects; use a dedicated cleaning agent to remove impurities on the ice surface, reducing the loss of additives.

Q3: What are the key design points for non-standard size track?
A3: Adjust the curvature radius and ice surface formula to compensate for size changes, such as increasing the proportion of ice surface additives when shortening the track length to maintain the coefficient of friction.
