Description
Technical Field
The invention relates to a process method for increasing the hydrophilicity of the metal surface of an air inlet system of a gas turbine.
Background
During the working process of the marine gas turbine, a large amount of fresh air needs to be continuously sucked from the atmosphere through the air compressor and compressed, the compressed air enters the combustion chamber to be mixed with the sprayed fuel and then combusted, and high-temperature gas generated after combustion pushes turbine blades to enable the turbine to rotate at a high speed and drive the propeller to work. Because the water mist content in the air of the marine environment is high, the water in the air is evaporated after compression, salt in the air can be separated out from the water and condensed, and part of the salt is adhered to the surface of the blade to corrode the blade and destroy the surface molded line of the blade, so that the performance of the gas compressor is reduced, the power of the gas turbine is reduced, and the performance and the service life of the gas turbine are influenced. Therefore, in order to ensure the intake quality of gas turbines and the like to meet design requirements, an air intake system is arranged at the air inlet of the combustion engine as an essential important component, and the aim of the air intake system is to filter and separate moisture and other impurities in the air.
Disclosure of Invention
The present invention is directed to a process for increasing the hydrophilicity of a metal surface of an air intake system of a gas turbine, so as to solve the above problems in the background art, and the hydrophilicity of the metal is greatly increased by performing a coating process on the surface of a metal substrate, so that the probability of capturing moisture when the moisture passes through the metal surface is greatly increased, and thus, the moisture in the air is separated.
The technical scheme adopted for achieving the aim is that the technological method for increasing the hydrophilicity of the metal surface of the gas turbine air inlet system comprises the following steps:
(1) diluting an alcohol-soluble epoxy acrylic resin material with an ethanol solution to obtain a resin solution;
(2) putting the metal base material into a container filled with resin solution, completely immersing the metal base material into the solution, and taking out after immersing for 2-3 minutes;
(3) standing, shaking or shaking to make the excessive solution on the metal substrate fall off, and placing in an environment with room temperature of 50 ℃ for 20-30 minutes to volatilize ethanol on the surface of the metal substrate, and observing that a layer of white resin is on the surface of the metal;
(4) and then the metal base material is placed in an oven at the temperature of 150-200 ℃ for heating and curing for 2-3 hours, after the metal base material is completely dried, the metal base material is cooled and taken out, and the resin is transparent after the metal base material is completely cured, so that the hydrophilic metal base material is obtained.
Further, the volume ratio of the alcohol-soluble epoxy acrylic resin material in the step (1) to the ethanol solution is 4: 6 to 3: 7 to obtain a resin solution.
Advantageous effects
Compared with the prior art, the invention has the following advantages.
1. The invention obtains better hydrophilic performance than the original metal surface by coating the resin coating on the metal surface, thereby greatly improving the trapping efficiency of the moisture in the air.
2. The resin coating is a macromolecular organic matter, does not react with salt mist chemically, has better corrosion resistance than common metal and has longer service life.
