Surface roughness using 2m by foot inspection temperature microcrystalline cast stone, cast stone surface finish pasting allow clearance of not more than 4mm. Height difference between adjacent cast stone no more than 2mm. And between the upper and lower cast stone pasting process may not have an inverse Cha appear. Paste the cast extrusion process between adjacent stone mastic knife scrape with tired microcrystalline cast stone, and cast stone with a damp cloth in a timely manner to clean the surface of the clay. Operation ①, concrete inner wall of the funnel to clean hand hammer will be higher than the concrete surface then pull rods, PVC casing all clean with a wire brush to clean the surface when pouring the concrete floor of the slurry with a brush to clean the surface dust cleared after guarantee concrete surface is smooth and no topsoil. ②, buried around the mouth end of the funnel member clean out the 30 × 3 welded to the bottom of the mouth angle, angle steel and embedded parts of the welding connection must be fully welded. High temperature microcrystalline cast stone, Tsinghua plastic (certified), microcrystalline cast stone by ShangYinXian Engineering Plastics Co., Tsinghua. ShangYinXian Qinghua Plastics Co., Ltd. (www.tyxqhgc.com) is Anyang, other leaders, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Tsinghua engineering leadership with the staff warmly welcome all inquiries negotiations to create a better future Tsinghua engineering.
