A green silicon PU construction process, construction of the base surface requires base surface using cement concrete foundation, it should meet the following requirements: 1, newly poured concrete should have sufficient curing time (not less than 28 days). 2, the surface roughness, sports equipment supplies, 3 m straightedge tolerance ≤3mm. 3, according to the design grade construction, basic strength c25 above, no cracks, delamination, and so on back to the sand. Second, the main construction method, construction technology base surface treatment process → → sealing primer layer construction → Construction → elastic elastic screed roller interface agent → Construction → Construction → crossed the finish layer 2, the construction techniques 1) first clean work surface, then the base surface moist with water, indoor sports equipment, with about 5% of dilute hydrochloric acid or oxalic acid spill and wash cement base surface, then rinse with water. 2) dried grass, for obvious protruding part polished, then the primer construction, the construction of the cement base surface hard, dry, clean, smooth, no oil and chalking. 3) to be dried after the construction of grassroots roller primer material good deployment, evenly roll in the cement base surface, play and bond closed. Third, the quality of protection measures 1, a quality target acceptance rate of 100%. 2, the construction program by the company of professional engineering and technical personnel carefully designed through repeated practice. Construction construction company operated by professional staff. 3. The implementation of the ISO 9001 quality material production management mode of operation, approach material certification, inspection reports. Expired or substandard products are not allowed into the site. Fourth, safe and civilized construction measures 1, the construction site should strictly abide by site management system. 2, promptly clean up the scene, prepared to handle the job site waste. Implementation of safe and civilized construction, so that workers Ended clear. 3, the construction site ready to do it neatly stacked materials, in strict accordance with the material specifications and models of different varieties classified put away and set up signs. Buy a table tennis table tennis tables to pay attention to what the size of ping-pong table standard dimensions: ping-pong table table size: 2740 × 1525mm table tennis Taiwan and Taiwan high: 760mm web width of 1.83 meters ping-pong table, ping-pong table laid high 0.1525 m: ping-pong table Venue: 1/73 football field, tennis courts 1/7 so big, with growth around 75cm high deflector 14m, width 7m rectangular, light (brightness to reach 10 lux) above the ground 5m. Table tennis table tennis table elastic elastic criteria are: release from table tennis from 300mm place, the rebound height of 230 ~ 260mm. If not in this range, the tables are unqualified. Ping-pong table is not the more the better play. Did not meet the standards of the elastic tables in long-term training will lead to action deformation. Ping-pong table style folding table, which is now often choose popular. Because favor of moving and storage. Family is recommended to use a folding table, which can reduce the pressure space. Outdoor production where select balls on the table have chosen fixed, Shenyang sports equipment, easily stolen. Friction coefficient and reflectivity standard table tennis table tennis table: friction coefficient: <0.6 4) reflectivity: MUNSELL system in no more than 15 degrees. Both also an important criterion for eligibility ping-pong table, but often is overlooked. Degree rotation of the ball loop, the forward momentum and the friction coefficient of correlation. For example, when a table, which is covered on the ash layer, loop the ball forward momentum could feel the slowdown. Reflective of play on the players is also very important, reflective too high is not easy to determine the trajectory of the ball. Color selection: ping-pong table very roughly, two colors. Green and blue. This is required by the ITTF two colors. The basic principles of tables and colors are white ball with blue tables and yellow ball with green table. ITTF to take care of early television, using the yellow ball with green tables mode. Now television technology has improved, the white ball can clearly be broadcast live. So amateur competition with the professional game are almost always used white ball blue table.
