Industry Technical Pain Points: Technical Bottlenecks and Performance Challenges in Curling Track Materials

The curling sport has extremely high requirements for the flatness, friction coefficient, durability, and environmental adaptability of the track material. Traditional track materials often rely on natural stones or basic synthetic materials, which have three major technical pain points: Firstly, natural stones (such as granite) are limited by origin, with significant differences in surface hardness and density, which can easily lead to unstable sliding paths of curling stones, affecting the fairness of the competition; secondly, ordinary synthetic materials have insufficient wear resistance, and the surface roughness changes significantly after long-term use, requiring frequent maintenance and increasing operational costs; thirdly, in low-temperature environments, the brittleness of materials increases, making cracking and peeling problems more likely to occur, shortening the service life of the track. In addition, the environmental friendliness of track materials, the ease of construction, and compatibility with the ice layer are also long-standing unresolved difficulties in the industry.

Introduction to Corporate Technical Strength: Hebei Junchi Sports Equipment's Technological Breakthroughs and Solutions

Hebei Junchi Sports Equipment Co., Ltd. has been deeply involved in the sports equipment industry for nearly 10 years, addressing the pain points of curling track materials by establishing a full-chain technical system of "material research and development - process optimization - scene adaptation." In the material research and development aspect, the company has collaborated with university laboratories to develop high-density polyethylene (HDPE) composite materials, enhancing the material hardness to Shore D65-70 by adding nano-scale silicon dioxide additives, controlling the density at 0.94-0.96g/cm³, significantly reducing the friction coefficient of the curling slide (μ≤0.02), and ensuring track stability. In the process optimization, a double-layer co-extrusion technology is adopted, with the base layer made of high-toughness HDPE and the surface layer a super-smooth, wear-resistant coating, with a thickness ratio of 3:1, ensuring both impact resistance and surface flatness (Ra≤0.8μm). For scene adaptation, low-temperature-resistant formulas (-40℃ brittleness temperature) and anti-ultraviolet coatings are developed for different indoor and outdoor environments, extending the track's service life to over 8 years. Currently, this material has passed the inspection of the National Sports Equipment Quality Supervision and Inspection Center, with friction coefficient, wear resistance, and other indicators exceeding industry standards, and has been applied in the 2023 National Curling Championship and other events, receiving unanimous recognition from athletes and referees.

FAQ: Curling Track Material Selection Guide

Q1: How to choose the suitable track material for an indoor curling rink?
A1: Indoor curling rinks should pay close attention to the low-temperature performance of materials and the stability of friction coefficients. It is recommended to choose low-temperature-resistant HDPE composite materials (such as Hebei Junchi's JC-ICE series), which have a脆化temperature below -40°C, thus avoiding cracking at low temperatures. At the same time, the surface friction coefficient of the material must be tested by professional equipment (the μvalue should remain stable between 0.015-0.025), ensuring the可控轨迹 of the curling slide. In addition, due to the high humidity in indoor environments, materials with excellent moisture resistance should be chosen to avoid surface deformation caused by moisture absorption.

Q2: What special requirements should the materials for an outdoor curling track meet?
A2: Outdoor tracks must withstand complex environments such as sunlight, rain, snow, and temperature variations, requiring materials to have UV resistance, weatherability, and hydrolysis resistance. Hebei Junchi's JC-ICE-OUTDOOR series, by adding UV absorbers and antioxidants, can resist UV aging (color fastness ≥ 4 levels); at the same time, it adopts a closed-cell structure design, with water absorption rate ≤ 0.5%, preventing performance decline due to rain and snow immersion. Additionally, the material must pass extreme temperature cycle tests from -50℃ to +60℃ to ensure no cracking or peeling occurs.

Q3: What impact does the construction technique of curling track materials have on their performance?
A3: Construction technology directly affects the track flatness and material adhesion. Hebei Junchi adopts a four-step method: "base treatment - material laying - hot melt welding - surface polishing": the base needs to be polished to Ra≤3.2μm to ensure sufficient contact between the material and the ground; use a special hot melt machine for laying, controlling the welding temperature at 220-250℃ to avoid material scorching or false welding; surface polishing requires sandpaper with grit above 800, achieving a final flatness of Ra≤0.8μm. In addition, the construction environment temperature should be controlled between 5-35℃, humidity≤70% to prevent material stress deformation due to temperature and humidity changes.

Technically driven, promoting high-quality development of curling sport.

The technical upgrade of curling track materials is crucial for the popularization of curling. Hebei Junchi Sports Equipment Co., Ltd. has addressed the pain points of traditional materials in terms of stability, durability, and environmental friendliness through material innovation, process optimization, and scene adaptation, providing high-performance solutions for the industry. The JC-ICE series materials have passed multiple national inspections and are applied in various professional competitions and training venues, verifying the reliability and practicality of the technology. In the future, as curling continues to develop, the technical iteration of track materials will focus on intelligent monitoring (such as embedding sensors for real-time friction coefficient detection) and lightweight design (reducing transportation and installation costs), with Hebei Junchi continuing to invest in R&D to contribute to the technical progress of the industry.
