The surface project is also equivalent to the government project and the image project. Its meaning is that some leading cadres for the purpose and interests of individuals or small groups, regardless of the needs of the masses and the local realities, do not hesitate to use the power of the hands to make the labor and the people are ineffective, but there are projects that may advertise their achievements for themselves and small groups. The image project not only wastes a lot of government investment and taxpayers' hard-earned money, but also sometimes causes major security incidents, which has caused many casualties and is very harmful. However, in the bonded steel reinforcement technology, if your "surface" project is not done well, it will have serious consequences.
You must be wondering when you see it here. Where does the bonded steel reinforcement technology come from? In fact, the surface engineering here refers to the surface treatment work. If the surface treatment of the bonded steel material is not good, it will have a great safety hazard for the subsequent reinforcement and use of the bonded steel. Here is a brief introduction by Mankate. We will give you a detailed introduction.
Divided into two parts, the first one is the concrete surface
The concrete surface should be cut off from the powder layer, grease stains and dirt, and then polished by an angle grinder to remove the surface layer of 1mm to 2mm thick. The larger depression is repaired and leveled with leveling glue. After grinding, the dust is blown off with compressed air, then the cotton is dipped in acetone. Wipe the surface and leave it to dry before use. After the surface treatment of the concrete, the chemically anchored holes on the front surface of the bonded steel and the fixed steel plate shall be recorded on site.
The surface of the second steel plate
The bonding surface of the steel plate shall be derusted and roughened. The steel plate does not rust or slightly rust and can be sanded with sandblasting, emery cloth or flat grinding wheel until metallic luster appears. The greater the roughness, the better. The graining should be perpendicular to the direction of the steel plate. If necessary, wipe it with absorbent cotton and acetone. Wait until it is completely dry. If the steel plate is seriously corroded, it must be soaked with moderate hydrochloric acid for 20 minutes to remove the rust layer, then rinse with lime water to neutralize the acid ions, and then use a flat grinding wheel to remove the grain.
Fortunately, the good bonded steel glue used can also supplement the loopholes that may occur in the above process. Mankate's bonded steel glue has no added quartz stone, light weight, no sag on the back surface, excellent anti-aging, chemical corrosion resistance and water resistance; small shrinkage after curing, large ratio range and long operation time. The specific gravity of Nanjing Mankate bonded steel adhesive is only 1.16, which is 10-20% lighter than the same volume on the market.
During the implementation of the project, Mankate will assign professionals to communicate with the engineering designer and the construction party, deepen the plan, and tailor the specifications of the bonded steel adhesive according to the needs of the project; after the use, there will be regular inspection and maintenance to ensure that all projects are completed on time.
