1. Field equipment assembly of FRP storage tanks.

A. Installation of winding equipment: vertical winding equipment is used for field winding, and the assembled mandrel is equipped with a spray gun. The whole winding process is controlled by computer according to the program.

B, mold installation: winding the upper and lower support rings of the equipment mold on site, adding vertical support ribs in the middle, and then sticking a layer of three-ply board and a layer of five-ply board outside. And a poly film is wound on the surface.

2. Installation and assembly of FRP tank top and mould.

A hoisting hole is reserved in the center of the tank top plate, and the prefabricated tank top is hoisted to the assembled mold by crane, and the installation and assembly are carried out in strict accordance with the hoisting specification. The tank top and the tank body are tightly butted, and the wood used in the tank body mold is cut according to the shape of the tank top to ensure tight butt joint.

3. Manufacture of FRP tank

The tank body is completed by two processes: lining spray forming and structural layer winding.

A. Forming of the tank: The tank is in direct contact with the storage medium, and its quality and performance are directly related to the service life and anti-leakage ability of the tank.

B tank winding: tank winding is the guarantee of the strength of the whole tank. The winding equipment is field vertical winding equipment, with the maximum winding diameter of 25m and the maximum winding height of 12in. Its winding parameters are controlled by computer, so that its strength and performance meet the design standards.

4, glass fiber reinforced plastic tank bottom manufacturing process.

The lower back cover is made directly on the foundation, first as the structural layer, and then as the lining layer. According to the technological requirements, the structural layer should be laid alternately with felt cloth, which has good permeability and bubbles are pressed out. Corner compensation shall be alternated at corners where the overlap between the felt layer and the cloth layer is less than 30 inches. The structural layer at the bottom of the tank body is made of 902# resin, and the inner lining is made of 330 1# resin. Small defects such as bubbles and delamination are allowed.

5. Assembly of FRP tank bottom.

After winding is completed, the tank body is connected with the tank bottom in a socket manner by a crane, and the joints are filled with resin mortar. Then, the seam between the inner wall of the tank and the bottom of the tank is sealed with felt and resin. According to the requirements of the construction drawing, make it into an arc with resin mortar, and then make a sealing layer with 8- 1Otnin thickness with felt paste. At the joint between the outer wall and the tank bottom, the resin is impregnated with glass fiber winding yarn, and the joint is made around the tank bottom, and then made of fiber felt or cloth.

Finally, pouring resin mortar, wherein the resin content of the mortar is operated according to the design; The tank body is connected with the tank bottom.

6. Lifting of FRP storage tanks.

Put the lifting disc into the lifting hole from the inside of the tank and fix it. The number of connecting ropes should be less than 7.
