The present invention relates to a repair and reinforcement method of the industrial equipment, in particular, if a crack and damage occurs in a part of the equipment of the industrial equipment to enable a quick and robust repair and reinforcement for cracks and breakage site without interrupting its operation It is about repair reinforcement method.

Generally, various facilities that produce products, such as power plants, steel mills, petroleum / refining plants, electronics, electricity, buildings, leisure industries, ships, and various factories, supply, transport, and discharge raw materials according to the purpose of establishment or products produced. Industrial facilities such as various types of pipes, ducts, ventilation equipment, and cleaning equipment are installed and operated.

In this way, industrial facilities, such as pipes, ducts, and cleaning equipment, are connected and installed in a number of components and are operated as separate systems according to the process of producing a specific product. Cracks and breakages occur, which is a high cost of maintenance and management.

For example, in the case of the cleaning tank included in the semiconductor cleaning equipment, which is one of the industrial facilities, chemicals (strong acids) are mainly desalted inside the nature of the purpose of use, so that partial corrosion and cracking may occur in the cleaning tank made of plastic or stainless steel. In case of occurrence, conventionally, the entire operation of the semiconductor production equipment should be replaced with a new washing tank, and then the operation must be restarted. Therefore, the cost of the disposal of the discarded washing tank and the purchase cost of the new washing tank are increased. Many problems have occurred such as waste of resources and mass production of industrial waste.

On the other hand, in the case of pipes or vent ducts included in semiconductor production facilities, a portion of the pipes or ducts, which are mostly made of metal due to chemicals, wastewater, exhaust gas, steam, etc., moving through the interior, are cracked and damaged, and thus, Leaks such as leaking of moving materials to the outside occur to contaminate the work site frequently. In the related art, a new replacement or cracking is performed while all the insides of the pipe and the ventilation duct are closed. Direct welding was performed to perform repairs, and then the pipes or the ventilation ducts were opened to be rerun.

However, the repair work of such pipes or ventilation ducts takes a lot of time in opening and closing the facility, ie, operating and restarting or repairing the facility, thereby lowering the productivity and reducing the airtightness of the welded cracks. As a result, the cost of the maintenance was a big burden on the user, and since a certain space must be secured for smooth welding during repair work, it is impossible to perform repair work in a narrow space. There was a following problem, and the spark generated during welding contained a risk of explosion or fire in response to the spilled material, and thus, the scope and location of the repair work by the welding were extremely limited.

Therefore, in order to solve the above problems, the present invention has a reinforcing sheet having excellent chemical resistance, adhesion, and adhesion, and is attached to the surface of a cracked part of an industrial facility to be cured by ultraviolet rays, thereby repairing the cracked part. It can be easily carried out to improve construction, convenience, and robustness, and can be maximized by using it regardless of its application range and location, as well as allowing semi-permanent use of repaired and reinforced equipment. And maintenance costs can be reduced, and the maintenance and reinforcement work can be performed while the operation of the equipment is in operation. .
