Abstract
Description
Technical Field
[0001] This invention relates to the field of offshore oil and gas extraction equipment and marine engineering technology, and in particular to an all-around adaptive paint mixing tool. Background Technology
[0002] Offshore platforms require continuous anti-corrosion painting operations, and the mixing ratio of the various paint components directly affects the painting process. Conventional mixing methods often fail to achieve thorough and uniform mixing, mainly in the following aspects: 1) Curing reaction defects and physical film formation defects In areas where the hardener / diluent ratio is improper or the mixture is uneven, the resin cannot fully cross-link, the dry film thickness is insufficient, internal solvent evaporation is difficult, and pinholes are easily formed, providing corrosion channels for seawater and chloride ions. Under the stress of vibration or thermal expansion and contraction of offshore platform equipment, cracking, peeling, or even detachment are highly likely to occur.
[0003] 2) The cost of rework is high in manpower and material resources If the coating effect is not up to standard, it must be completely sanded, cleaned, and repainted, which not only consumes a lot of materials but also generates more manpower, seriously delaying the project schedule.
[0004] 3) It can easily cause equipment failure and lead to time-consuming cleaning. Uneven mixing can easily cause undispersed lumps, semi-solidified substances, or impurities to clog the pipes, nozzles, and filters of spraying equipment. This not only leads to frequent interruptions in spraying operations but also increases the time spent cleaning equipment and replacing parts.
[0005] 4) The risk of secondary pollution from abnormally concentrated volatilization of VOCs (volatile organic compounds) and increased hazardous waste. Uneven mixing can lead to excessive amounts of thinner in certain areas, causing a rapid and concentrated evaporation of solvent in those areas during the initial stages of coating and drying. This not only affects the health of workers but also causes a surge in local VOC concentrations, resulting in excessive fugitive emissions. Simultaneously, waste paint, waste solvent, and waste paint residue will increase significantly. If storage containers are not properly sealed, residual solvents in the waste residue and waste liquid will continue to evaporate, causing secondary pollution.
[0006] Therefore, a dual-drive, sealed, high-efficiency paint mixing tool is the key to solving this problem. Summary of the Invention
