LARGE CHEMICAL ENGINEERING EQUIPMENT LINING ANTI-CORROSIVE PLATE MANUFACTURING METHOD

摘要

The invention relates to a large-scale chemical equipment and a manufacture technology of a lining anti-corrosion board of the large-scale chemical equipment. The manufacture technology comprises the following steps of: (1) carrying out sand-blast cleaning on an inner wall; (2) carrying out roll painting; (3) setting out a flitch, gluing a pressed vacuum rope at the inner wall of the equipment in the process of vacuumizing, and gluing a board; (4) welding; (5) detecting; and (6) reinforcing and shaping by steam. The equipment comprises a tank body, wherein the outer surface of the tank body is provided with a plurality of vacuum mouths, the inner wall of the tank body is provided with the anti-corrosion board connected with by binder, the vacuum rope is arranged between the board and the inner wall of the tank body, and wrinkles which run along with the vacuum rope are formed on the surface of the board. According to the invention, the vacuum rope is glued at the inner wall of the equipment, so that the vacuum gluing strength can be preferably enhanced, and the expansion or the contraction of the board lining can be carried out along with the wrinkles formed on the surface; the technical difficulty which is the lining anti-corrosion material of the large-scale chemical equipment be easy to fall off can be solved, and the technology is more energy-saving, environments-friendly, low in energy consumption, and low in cost; and various anti-corrosion equipment machined and manufactured by the technology is high in lining strength, corrosion resistant, and long in service life.
