Problems solved by technology

[0002] Sulfuric acid containers are generally tanks for storing sulfuric acid in the chemical industry. As we all know, sulfuric acid has strong oxidizing and corrosive properties. When the above situation occurs, it is generally used to stop the operation of the equipment, and perform open flame electric and gas welding to plug the leakage in a special environment without pressure and temperature. The above operation method not only delays production, but also easily causes safety hazards such as fire or explosion. The economic losses caused are even more immeasurable
If the sulfuric acid equipment is ignored, with further development, it will affect the normal use of the equipment and pose a great threat to the safety of on-site workers.

Embodiment 1

[0032] A kind of glue for repairing and pouring sulfuric acid container equipment. The glue for pouring is made of the following raw materials in parts by weight: 10 parts of foaming alkali, 7 parts of aluminum dihydrogen phosphate, 10 parts of kyanite, and 10 parts of 800-mesh graphite powder 1 part of siliceous compacting agent, 15 parts of furan resin solution and 1 part of sodium fluorosilicate.

[0033] A method for repairing a sulfuric acid container using pouring glue, comprising the steps of:

[0034] Step 1: Confirm the corrosion point area of ​​the sulfuric acid container, and cut the corrosion point;

[0035] Step 2: Prepare new steel plates for repair welding according to the size of the corrosion spots described in step 1. The area of ​​the new steel plates is greater than the cutting area of ​​the corrosion spots; five vent holes will be prepared on the new steel plates for repair welding. A vent hole is respectively arranged on the upper middle position, the lo...
