A construction method for manufacturing FRP floating trays by spraying process

Abstract

The invention discloses a spraying method glass steel floating disc and a construction method. A floating disc plate of the floating disc comprises a lower conducting layer, a lower glass steel layer,a polypropylene honeycomb layer, an upper glass steel layer and an upper flame retardant conducting layer. A main tool is a glass steel spraying gun; the glass steel spraying gun pulls out continuousglass fibers through a quick motor; scissors are used for quickly cutting the fibers; a high-pressure pump sends out resins; and the resins, the fibers and a proper amount of curing liquid are mixedfor high-speed spraying to achieve the purpose of quick construction. The continuous glass fibers are used for replacing hand pasting method short-cut felts and glass fiber cloth. The continuous glassfibers are manufactured by such processes as high-temperature melting, wire drawing, winding and weaving with glass as raw materials; and main components are silicon dioxide, aluminum oxide, calciumoxide, boron oxide, magnesium oxide and sodium oxide. The constraints of low efficiency and low speed of a hand pasting glass steel floating disc can be solved; the purposes of shorting the construction period, simplifying the process and improving the product quality in the glass steel floating disc construction process are achieved; and the labor cost can be effectively saved.

Description

technical field [0001] The invention relates to an improvement technology of an oil storage tank of an oil depot. It particularly relates to the construction method of the floating plate of the floating roof oil storage tank. Background technique [0002] With the increasing scale of oil storage tanks and oil depots, the requirements for floating trays of floating roof oil storage tanks are getting higher and higher. In recent years, there have been many accidents of floating roof storage tanks being struck by lightning, and the most serious one is the explosion accident of internal floating roof storage tanks. Many of these accidents of internal floating roof storage tanks are caused by the poor sealing of the floating plate and the internal memory of the storage tank. In explosive gas, it is caused by excessive oil and gas concentration near the gas outlet of the storage tank. At the same time, the loose sealing of the floating plate also causes a large amount of hydroca...

AI Technical Summary

Problems solved by technology

[0011] 1. The production efficiency is low. The production of FRP floating discs by hand lay-up method does not count the lapping and dismantling of the formwork and subsequent construction, only the paste-making time of the FRP floating discs. Taking a 30-meter-diameter storage tank as an example, it takes about 2-3 months ;

[0012] 2. The quality cannot be guaranteed. Due to the slow speed of the production of FRP floating discs by hand lay-up, various additives are added manually, which not only affects the quality of FRP, but also often causes the curing speed of FRP to be too fast or too slow, which affects the quality and production of FRP floating discs. efficiency;

[0013] 3. The waste is serious. Due to the artificial mixing of resin and curing agent, the amount of mixing can be more or less each time, which cannot be accurately measured. Moreover, the structure of the FRP floating plate is complex, with various accessories, and the construction speed cannot be unified, which often results in the inability to specify the time. In this way, the mixed resin is often left, resulting in a lot of waste of materials and increasing the construction cost.
