Basketball court size: 32000mm×19000mm
1、 Course:
It is a solid rectangular plane without obstacles. For all the major official games of the Basketball Federation, the measurement of the court should start from the inner edge of the boundary. For all other games, the appropriate department of all basketball federations door , has the right to approve the existing course within the following size range: length reduction four M, width reduced two Meters, as long as their changes are proportional to each other. Ceiling or lower barrier height at least seven Meters. The lighting of the stadium should be uniform and the luminosity should be sufficient. lamp The placement of optical equipment shall not obstruct the vision of team members. The size of all newly-built courts should be consistent with the requirements specified by all the basketball federations in major official competitions: long twenty-eight M, width fifteen Meters.
Due to the unique molecular structure of agricultural production system silicon, which combines the properties of inorganic materials and agricultural production system materials, it has the basic properties of low surface tension, low viscosity temperature coefficient, high compressibility, high gas permeability, and good characteristics such as high and low temperature resistance, electrical insulation, oxidation resistance stability, weather resistance, flame resistance, corrosion resistance, harmless and tasteless, and physiological inertia, It is widely used in aerospace, electronic and electrical, construction, chemical industry and other industries, among which the agricultural production system silicon is mainly used in sealing, bonding, lubrication, coating, surface activity, defoaming, foam suppression, waterproof, moisture-proof, etc. The application of agricultural production system silicon in stadium materials is a strong combination, which not only enhances polyurethane The original characteristics change to overcome the shortcomings of polyurethane. So, silicon PU Course materials are the product of the times and the necessity of development
① Superior weather resistance: silicon PU It will not fade, harden, soften, or whiten the surface due to changes in outdoor high and low temperature climate. It can maintain its bright color for a long time even in strong ultraviolet, ozone, rain, high temperature difference and other climatic environments.
② Super abrasion resistance: silicon PU The surface layer adopts the method of adding silicon resin particles. Its structural characteristics remain stable for a long time, and its hardness is moderate. Its wear resistance meets the needs of long-term high use frequency.
③ Good stain resistance: silicon PU The surface course is dense and moderately hard. It is not easy to crack, peel, fade and whiten, and the court can be kept as clean as new for a long time through simple washing.
1、 Construction procedure:
surface treatment —— cutting V Zigzag seam —— Grinding and pickling —— Caulking —— Replenish ponding —— Ground leveling —— Apply elastic layer —— Scratch reinforcing layer —— construction Interfacial agent —— Construction surface course —— Scribing —— Site clearing is completed.
