Problems solved by technology

However, the existing water-based coatings and construction techniques are used on the surface of oil tanks in caverns or soil-covered storages, which often cause the paint to fall off and cause the oil storage tanks to rust, which cannot meet the requirements for use.

Embodiment Construction

[0059] In order to further understand the content of the invention, features and effects of the present invention, it will be described in conjunction with the following examples:

[0060] A modified water-based paint coating process for oil tanks used in petroleum caverns / earth-covered warehouses, comprising the following steps:

[0061] (1) Surface treatment of steel before painting

[0062] a. Degreasing

[0063] Before the steel surface is painted, if the steel surface is polluted by grease, wax or acid-base chemicals, use a neutral detergent to scrub the polluted surface to clean the dirt to ensure that there is no oil or debris;

[0064] b. Sandblasting

[0065] Conduct pre-inspection on the steel surface before sandblasting. If defects such as missing welding, broken welding, cracks, pulls, and perforations are found, they should be reported to relevant departments for rectification;

[0066] Before painting, the outer wall of the oil tank should be subjected to shot...

Abstract

The invention discloses a modified aqueous paint coating process for an oil tank for a petroleum cave depot / an earthing storeroom. The process comprises the following operating steps of: (1) surface treatment before steel product coating; (2) environmental control; (3) coating construction; and (4) quality control. The invention formulates the coating process suitable for coating the oil tank in the petroleum cave depot / earthing storeroom with the modified aqueous paint. According to the process disclosed by the invention, the modified aqueous paint can be uniformly sprayed to the wall surface of a storage tank to satisfy the demand in the field of petroleum, so that the aqueous paint is in full contact with the oil tank. Moreover, the paint will not fall off from the oil tank, so that the coating quality is guaranteed, and the problem that the oil tank is rusted as an existing aqueous paint spraying method cannot achieve the using demand to lead to fall-off of the aqueous paint is solved.

Description

technical field [0001] The invention relates to the field of oil tank coating, in particular to a modified water-based paint coating process for oil tanks used in petroleum caverns / soil-covered warehouses. Background technique [0002] Oil tanks in oil caverns or soil-covered tanks have good concealment and strong protection capabilities. The oil tanks in this environment are located in a relatively airtight environment with high humidity. Because it is different from the usual above-ground oil tanks, the selection and construction process of the anti-corrosion coating on the surface of the environmental oil tank needs to consider its particularity. [0003] At present, oil-based paints are usually used for anti-corrosion in ground storage tanks, but oil-based paints have higher requirements on the surrounding environment of painting, and the painting process is unsafe and prone to danger. Due to the low flash point of organic solvents, they are easy to catch fire and explo...
