Stick steel adhesive steel construction preparation

Steel sticking glue to stick adhesive steel construction steel construction 1 ready to clean up the construction site, will hinder the construction of items removed; To carry out the construction need of people, material, machine; Safety education, safety disclosure. 2 surface treatment to ensure good bonding between steel plate and structure, the concrete component surface should be dealt with in accordance with the following methods: (1) of the original concrete component adhesive surface, can scrub brush touch high efficiency washing the seam an agent, rinse after brushing oil contamination in addition to surface, and the bonding surface polishing, get rid of 2 ~ 3 mm thick surface, until completely new face, and oil-free compressed air to remove dust or rinse off with clear water, after being completely dry use absorbent cotton to wipe the surface of acetone. Steel plate bonding surface, shall be rust and rough handling. If no rust or mild steel corrosion, can use sand, emery cloth or flat grinding wheel grinding, until a metallic luster. The greater the roughness, the better, polishing lines should be with vertical steel plate stress direction. Then use absorbent cotton with acetone to wipe clean. Such as steel corrosion is serious, should be moderately with hydrochloric acid soak for 20 minutes, the rust layer falls off, again use lime wash and acid ions, in the end, flat grinding wheel grinding out the grain.
