Wuhu silicon PU manufacturer of silicon PU stadium cost manufacturers supply

Silicon PU basketball court construction process there are several points should be emphasized: Shenzhen, the highest Austrian-Sports last year in the construction process, the construction of the stadium ground has a wealth of experience, asphalt-based silicon pu basketball court: first base requirements: surface even solid, no oil, no unstirred open asphalt block, smooth and no cracks, no bad side of packing, no pockmarked face, seams are smooth, without water blocking phenomenon, compaction density of less than 95%, in the medium grind After the press pressure, no significant wheel tracks, no weak skin, free of loose topsoil, waves and other phenomena, flatness ruler error is less than 3mm 3mm, flatness passing rate greater than 90%, there is a certain drainage slope to ensure the vent water. New asphalt base Nature Conservancy of not less than 28 days, so the asphalt high boiling volatiles volatile completely, silicon PU material to ensure a good bond with the base (2) Basic processing:. A, cleaning: water with detergent solution or detergent fine water fluid, cleaning the base surface, then rinse with water, after basic cleaning should be no dirt was loose and other floating debris. To mark a good bit of the identification mark water cleaning. B, leveling: professional underlying TB-202 by Group A: Group B = 1: 2.5 (weight ratio) ratio Stir (construction consistency can be adjusted with water), with plastic scraper two points above the base surface scratch, requiring gap base surface must be filled, sealed, to ensure that no pinholes, smooth surface dryness. Does not affect the later construction, the base surface if the gap is large, the first A component may be added together equal parts of sand (40-80 mesh) at Scratch, Scratch stir. C, water leveling patches: according to the new requirements of the cement foundation treatment. Our Austrian crown-Sports silicon PU construction material (elastic layer surface → reinforcement layer → → line) 1, the elastic layer: front flexible layer construction should be carefully examined in order to confirm the foundation dealt elastic layer construction, an elastic layer ( TB-002) as a one-component material, simply adjust suitable construction with thinner consistency, applied to the substrate surface with a toothed blade, every scratch coating thickness can not exceed 2.0mm, scraping every time interval before a dryness of Associate (usually about 10 hours, depending on the scene weather conditions) until scraping to a desired thickness. Note leveling effect when Scraping, if not leveling scraping teeth marks, need to pay more in order to ensure that the surface leveling diluent. If the temperature is low (<10 ℃ = and the relative humidity is low (<60% = must be added (3-8%) water and stir evenly coated scratch, in order to accelerate the curing material, reducing the interval, the amount of water depending on site specific weather It may be, should be avoided under construction in strong sunlight. The elastic layer to dry after using the water method to test the surface flatness, the water at the patch with TB-002 smooth surface or if particulate debris piled at the mill required or other tools can be trimmed flat reinforcing layer construction 2, reinforcing layer: reinforcing layer (TB-003) for the one-component materials, construction methods consistent with the elastic layer if the reinforcement layer design thin (less than 1mm), tooth scraping Scraping difficult leveling, usable plastic scraper division multiple channel coating, must ensure that the smooth surface after scratch. If during construction debris mixed or scratch there is unevenness of the surface layer is required to be carried out after trimming smooth 4 construction, crossed the standard size measurement positioning, mark the boundaries of the location, along with the boundaries on both sides of textured paper posted on the court, with a special marking paint (TB-207) between brushing textured paper, until the surface is dry After the tear Masking .TB-207 two-component material, must be prescribed proportion (A: B = 9: 1) to A, B two groups were fully mixed, brushing two minutes if the court surface. rough surface, the first surface layer can add 20% sand painting dedicated to the barrier cuff 5 Note:.. a, must weigh the deployment of materials accurately and stir b, the entire construction process every step of the pre-construction You must keep the surface clean c, indoor venues must ensure good ventilation after d, venues laying need to maintain in order to be put into use more than 5 days 3, the surface layer: For the surface layer (TB-205) as a two-component water-based materials, must be prescribed proportion (A group: Group B = 9: 1 (weight ratio)), stir the two components, (ratio allowed to affect the curing effect of the surface layer, directly affects the performance of the surface layer) diluted with water Construction of consistency, the general added 50 ~ 80% (TB-205 weight, according to the actual situation may be), with a special gun division multiple channel sprayed on strengthening the level required of the surface roughness of adding special sand spray can. The lowest temperature below 5 ℃ not suitable for construction, keeping dry soak 10 hours after construction of various types of court surface layer reference practice:. a) basketball court: a three-channel spray, the first and second channels plus 15% (TB-205 weight) special sand, every TB-205 the amount of about 0.15kg, the third without sand (amount of about 0.1kg), when the sand should be first A component with a special sand mix well, then add component B stirring evenly, add water dilution; three seconds restricted area should be done three sand and a sand without (a total of four channels) b) Tennis: Spray three points, the first increase of 50% sand, the second increase 50% Sand, the third without sand. c) badminton, volleyball: no sand spraying three.
