The scope of Haibei silo plugging project is welcome to inquire for details, and the KY2 acid-resistant and temperature-resistant cement prepared in proportion will be directly applied to the surface of the substrate that has been repaired with a trowel, and the coating should be evenly applied, and the thickness of each coating should be mastered; The thickness is 1. Around 75mm. The application should be done continuously in a certain directional order. FRP glass cloth paste reinforcement, thickness about 0. 5mm。The second KY2 acid-resistant and temperature-resistant cement is scraped with a thickness of 1Around 75mm. KY2 acid-resistant and temperature-resistant cement scraping inspection: there is no concave and convex surface after application, and the thickness should be uniform. If there is still a convex phenomenon on the surface, gently smooth it with sandpaper, and fill the dented places with KY2 acid-resistant and temperature-resistant cement.

Angle of scissors to the ground: 45 degrees. Scaffolding materials should be quality reviewed as needed, and can only be used after they are qualified. The cross-section (all layers) must be inspected and accepted before use. Scaffolding should be carefully evaluated in stages, and problems should be corrected in time, and each stage is divided into: a: before scaffolding is erected. B: Before applying the working process load C: The height is increased every 10m. d: After reaching the design height. The construction of the operation process should follow the design, and the formwork support, cable wind rope, water pump pipe, etc. shall not be overloaded. During the use of scaffolding, it is strictly forbidden to dismantle the vertical and horizontal poles, sweeping rods, connecting wall rods, supports, railings, pedals, etc. at will. Approved by the technical management department. It is strictly forbidden to carry out excavation work in foundations, scaffolding and adjacent areas, and if excavation is required, safety measures should be taken and agreed by the management of the workplace. 
+05mm thick coarse grid glass cloth. The dust removal platform at the bottom of the chimney and 1 meter above the intersection with the chimney flue is pasted with KY2 acid-resistant and heat-resistant clay + FRP reinforcement. 3.The thickness of 5mm is uniform and smooth, and the average thickness is 35mm。The chimney wall is brushed with KY2-3 acid-resistant paint 03mm, smooth surface This anti-corrosion modified chimney is reinforced with acid-resistant cement and glass wire. Horizontal chimneys, dust collection platforms, inner surfaces of chimney linings, surfaces of parts in contact with flue gases in the chimney, and areas that can be swept away by flue gas within 10 m of the chimney top. Flue gas. Acid-resistant cement anti-corrosion and anti-seepage coatings should be used at the leakage site. 
Painting interval: the primer should be naturally cured for no less than 24 hours and not more than 48 hours. The topcoat can be painted, and the topcoat can be applied at intervals after the surface of the above coating is dry. The coating of various paints should be subject to the material instruction manual. Strengthen the intermediate inspection of the coating process: when the coating is coated, the coating thickness and the number of times should be checked, and the wet film thickness should be controlled with a wet film thickness gauge.
