Manufacturing process of double-layer storage tank with glass fiber reinforced plastic anti-corrosion linings

Abstract

The invention discloses a manufacturing process of a double-layer storage tank with glass fiber reinforced plastic anti-corrosion linings. The manufacturing method comprises the steps of manufacturingend sockets at the two ends of an inner-layer tank body, manufacturing a middle cylinder body, manufacturing the glass fiber reinforced plastic anti-corrosion linings on the inner walls of the end sockets at the two ends of the inner-layer tank body, manufacturing the glass fiber reinforced plastic anti-corrosion lining on the inner wall of the middle cylinder body of the inner-layer tank body, butting the end sockets of the inner-layer tank body and the middle cylinder body, welding circumferential welds, and repairing the glass fiber reinforced plastic anti-corrosion linings at the butt joints of the end sockets of the inner-layer tank body and the middle cylinder body. The glass fiber reinforced plastic anti-corrosion lining on the inner wall of the middle cylinder body of the inner-layer tank body is manufactured by adopting continuous lining and coating integrated equipment to achieve continuous lining and resin glue solution coating of glass fiber cloth. The continuous lining and coating integrated equipment comprises a roller carrier and a lining and coating assembly arranged in the middle cylinder body of the inner-layer tank body. The defects of a spray forming method anda hand lay-up forming method in the prior art are overcome, the quality of the glass fiber reinforced plastic anti-corrosion linings of the double-layer storage tank is guaranteed, and the productionefficiency is improved.

Description

technical field [0001] The invention relates to the technical field of tank body production, in particular to a production process of a double-layer storage tank with a glass fiber reinforced plastic anti-corrosion lining. Background technique [0002] The explosion-proof barrier skid-mounted refueling device is a double-layer storage tank structure, in which the inner tank is made of carbon steel and there is a gap between the outer tank and the outer tank. Due to a certain chemical liquid contained by the customer, it is corrosive to carbon steel materials and cannot coexist with carbon steel materials. For this reason, the manufacturing process of the double-layer storage tank on the explosion-proof barrier skid-mounted refueling device is improved, specifically, the inner wall of the carbon steel tank is produced to produce a glass fiber reinforced plastic anti-corrosion inner lining. [0003] In the prior art, there are mainly two methods for making the FRP anti-corros...

AI Technical Summary

Problems solved by technology

However, the physical properties of the FRP anti-corrosion lining made by the spray molding method are poor, so for the FRP anti-corrosion lining with high requirements, the hand lay-up method is mainly used at present.

The hand lay-up method uses glass fiber cloth as the main material, manual lining, manual brushing of resin glue, and manual pushing to drive away air bubbles. The physical properties of the FRP anti-corrosion inner lining are relatively good, but the disadvantage is that it requires manual labor. The production efficiency is low, and the quality of hand lay-up is related to the skill and responsibility of the operator, which affects the stability of its quality
