Problems solved by technology

[0004] This is mainly because the origin of crude oil is different, and the components and impurities contained in crude oil are also different. Crude oil contains a large number of ions and molecules that affect corrosion, including CL-, HCO3, SO4, H2S, CO2, etc. These ions or molecules can be combined with The iron undergoes electrochemical reactions, and due to the frequent operation of the hand valve, the erosion of the sand and stones contained in the incoming oil on the bottom of the floating plate will cause damage to the anti-corrosion layer, and at the same time aggravate the occurrence of corrosion, and the floating plate cannot use measures such as anode protection , can only rely on anti-corrosion, once the anti-corrosion layer is damaged, it will soon produce more serious corrosion

preparation example Construction

[0055] The present invention at first provides a kind of preparation method of novel composite carbon steel floating plate, comprises the following steps:

[0056](1) Pretreatment before construction: Before construction, carry out derusting treatment on the carbon steel floating plate, and remove the floating rust on the bottom plate and side wall of the carbon steel floating plate; Brush a layer of special primer on the inner surface of the through-hole for construction, so that the surface of the bottom plate, the surface of the side wall, and the inner surface of the through-hole are all infiltrated with the special primer; The surface of the part is puttyed to make the surface of the bottom plate and side wall smooth;

[0057] (2) Through hole construction: The through holes on the carbon steel floating plate include manholes, guide column openings and floating plate outrigger openings. After the pretreatment in step (1) is completed, the through holes are constructed: fi...

Embodiment 1

[0070] In this example, the prepreg of the light-cured FRP material used is the CP201 ​​prepreg sheet produced by Beijing Yingren Technology, with a thickness of 1.5mm and a width of 2 meters; it uses 470 light-curable resin and E glass fiber Chopped strand mat is the main raw material, which has high strength and corrosion resistance. In this embodiment, the interface glue is 470 photocurable resin, and the thickness of the coating is about 0.1mm.

[0071] A method for preparing a new type of composite carbon steel floating disc. A conventional carbon steel floating disc is manufactured in a floating roof oil tank according to the traditional method. After the carbon steel floating disc is manufactured, the immersion part of the carbon steel floating disc is subjected to photocuring The construction of FRP materials includes the following steps:

[0072] (1) Pretreatment before construction: Before construction, carry out derusting treatment on the carbon steel floating plat...

Embodiment 2

[0082] A novel composite carbon steel floating disc is prepared through the preparation method of Example 1:

[0083] The main body of the floating plate, the inner wall of the through hole 1 is painted and / or laid in turn with a special primer layer A4 and a prepreg layer 5 of light-cured FRP material from the inside to the outside. An annular reinforcing ring 6 is pasted on the surface of the through hole, and the inner circle of the reinforcing ring is facing the inner diameter of the through hole; the special primer layer, the prepreg layer of light-cured FRP material and the reinforcing ring constitute the corrosion resistance of the through hole. layer;

[0084] The main body of the floating tray, its side wall 2 and bottom plate 3 are painted and / or laid with a special primer layer B7, a first layer of prepreg layer 8 of light-cured FRP material, and a second layer of light-cured fiberglass material from the inside to the outside. The prepreg layer 9 and conductive lay...

Abstract

The invention discloses a novel composite carbon steel floating plate and a preparation method thereof. After a conventional carbon steel floating plate is manufactured in a floating roof oil tank, the immersion part of the carbon steel floating plate is constructed, the inner wall of a through hole is sequentially coated with and / or paved with a special primer layer A and a prepreg layer of light-cured glass steel materials from inside to outside, the tail end of the through hole and the surface layer of a bottom plate are adhered with an annular reinforcing ring, and the inner circle of thereinforcing ring is right opposite to the inner diameter of the through hole; and the side wall and the bottom plate are sequentially coated and / or paved with a special primer layer B, a prepreg layerof a first layer of light-cured glass fiber reinforced plastic materials , a prepreg layer of a second layer of light-cured glass fiber reinforced plastic materials and a conducting layer from insideto outside. According to the novel composite carbon steel floating plate and the preparation method thereof, a glass fiber reinforced plastic reinforcement layer is constructed on the lower surface of the carbon steel floating plate, so that the service life of the carbon steel floating plate can be greatly prolonged, and the running safety of the floating plate is improved; and by adopting the novel light-cured glass fiber reinforced plastic prepreg construction process as the glass fiber reinforced plastic main body of the composite floating plate, the construction speed can be greatly improved, and the construction difficulty is reduced.

Description

technical field [0001] The invention relates to a novel composite carbon steel floating disc and a preparation method thereof. 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, the concentration of oil and gas near the exhaust port of the storage tank is caused by excessive concentration. At the same time, the loose sealing of the floating plate also causes a large amount of hydrocarbon gas to volatilize, causing serious environmental pollution and seriously af...
