Professional badminton court flooring for outdoor basketball court conversion

Primary Materials and Structure: Polyether series color paste (306B), prepolymer (306A) made from imported TDI (or MDI) materials, and black rubber granules

PE prices in Asia this month are stable but weakening, mainly due to a drop of $3 USD per ton. For LDPE, Iran film-grade material spot ship cargo is quoted at $136~$138 USD (CFR), while Mexico and European film-grade materials are priced at $136 USD (CFR). In the domestic markets of East China and North China, the factory price of imported film-grade materials is 18~114 yuan, down by 2 yuan from the previous period. For LLDPE, a Middle East manufacturer initially quoted December film-grade material at $121 USD (CFR), while traders initially sold Middle East and Asian products for $118~$121 USD (CFR). In the middle of the period, some December shipments from Middle East manufacturers were priced at $116~$118 USD (CFR).

Cheers to the professional media in the sports flooring industry, representing public sports facilities! Kudos to the Administration for Market Regulation for leading the charge! Praise to every staff member involved in setting the standards! Thank you for your diligent efforts, which have yielded a rich harvest of both professionalism and foresight.

Low-E glass coatings are well-protected as they are applied to the inner surface of double or triple glazed windows. In contrast, it is challenging to achieve low radiation energy in building films commonly used for lightweight structures like airport and train station canopies. These films require strong adhesion and resistance to wear and weather. While there are coatings with good adhesion, they do not meet the desired low radiation performance. With funding from the German Federal Ministry of Economics and Technology, the Bavarian Center for Applied Energy Research in Germany has developed a method to coat common building films or fabrics with a mixture of polyurethane, aluminum particles, and pigments, achieving a more ideal low radiation effect.

To prevent local bubbling and peeling after the paving of the adhesive surface during summer construction, strictly control the compactness of the subgrade to avoid the cement foundation from being unevenly compacted, leading to peeling and delamination, which may cause the adhesive surface to be pulled apart.

ETPU granules effectively accumulate and release energy after each application of force, with their unique high molecular honeycomb structure providing powerful shock absorption and rebound, ensuring the track maintains excellent performance year-round. The "Damping" technology incorporates ETPU into the track, allowing each step to be compressed, expanded, and反弹, reducing the impact on the knees and ankles during exercise. Odorless, meaning no smell, zero VOC, zero formaldehyde, free of carbon monoxide, soluble lead, and 18 polycyclic aromatic hydrocarbons, with high solid content. Advanced "Depurate" technology ensures the system is free of any volatile harmful substances like benzene and formaldehyde, achieving true odorless and harmless properties.

After 1000 hours of accelerated aging, the physical energy reduction is less than 1%, and the test results meet domestic standards. The unique "Durable" surface technology provides the track with excellent aging resistance and frost-thaw resistance, preventing yellowing, hardening, and loss. It maintains physical energy from 65 degrees to minus 20 degrees, suitable for frequent use in professional competitive events with spiked shoes, and boasts an exceptionally long service life.

The half-life of DCP at 18 degrees is 1 minute, and at 13 degrees, it's also 1 minute. Therefore, during the preparation of the mixture, it's best to keep the temperature below 12 degrees. For products that have specific odor requirements, another bridging agent, BIPB, can be used, usually in combination with T:IC. The dosage of DCP is typically .5-.6 Phr for flat foam and in-mold small foam, and .8-1.0 Phr for extrusion foaming. Of course, there may be slight adjustments or different usage methods. Currently, the two most commonly used blowing agents are zinc oxide powder and zinc stearate powder. We used to mix both, but now we only use zinc oxide.

Just now, the newly revised mandatory standard for plastic tracks, "Synthetic Material Surface Sports Fields for Primary and Middle Schools" GB36246-2018, was officially approved on the Standardization Administration website, with the release date set for May 7th. After the implementation of the new national standard, the "Part 1: Synthetic Material Surface Sports Fields for Primary and Middle Schools" GB/T19851.1-2005, which has been in effect since its release in 2005, will be invalidated. The sports field material industry will now be measured by a new yardstick.

Youth strength and sports strength are interconnected with the dream of a sports powerhouse. As an important part of health and the sports industry, comprehensive sports fitness has gradually permeated into schools, sports venues, fitness trails, and the daily lives of the people. Therefore, the healthy development of the green sports materials industry is particularly important. The release of the new national standard symbolizes the beginning of the quality development era for the sports materials industry.

According to information, the revised standard is based on a comprehensive outcome of science, technology, and practical experience, aiming to ensure student sports health, enhance product quality, and guide industry self-discipline. It considers various requirements such as environmental protection, sports protection, durability, comfort, aesthetics, and environmental protection, while being systematic, scientific, and applicable. The new national standard, while meeting usage requirements, optimizes the allocation of social resources, providing guidance and basis for the design, construction, and acceptance of synthetic surface sports fields in primary and secondary schools. This, in turn, offers a healthy exercise environment for students, cultivates a lifelong sports awareness, and promotes the green and healthy development of school sports.
