Hydropower Generation

Hydropower is the process of utilizing thepotential energy of water flows from high places such as rivers and lakes, converting it into the kinetic energy of a water turbine,which drives a generator to produce electrical energy.It is a high-qualityrenewableclean energysourceand isthepreferredinvestment directionintheprocessofenergydevelopment.

Themain anti-corrosiontargetsofthesteelstructuresinhydropowerfacilities include various types of gates,trash racks,hoists，shiplifts,pressure steel pipes，cleaning machines，embedded parts,and dam navigation steel structures, which are collectively referred to as hydraulic steel structures.

The purpose of corrosion protection for hydraulic steel structures is to minimize the loss caused by metal corrosion, extend its service life,and provideacertaindecorativeeffect.

Althoughhydropower stationsdonothaveseriousproblemswithdust and exhaust emissions,some equipment isinadamp environment fora longtime, andevensubmerged inwaterforalongtime,whichalsoplacesthemina moderatelyseverecorrosionenvironment.Thekeytocorrosionpreventionin hydropowerstations liesinwaterproofingand moistureproofing,especially in areaswheredryandwetconditionsalternate.

Before formulating the corrosionprotection systemforhydraulicsteel structures,a scientificand systematic analysis shouldbe conducted on the corrosionenvironment in which they arelocated.According torelevant standards,the corrosion environment shouldbe evaluated and classified. Only based on this,can an effective coatingsystem and construction plan that meet anti-corrosionrequirementsbedesigned.

Thecorrosionenvironmentofhydraulicsteelstructuresisdividedintotwo parts:naturalenvironment andoperatingconditions.Bothofthemdirectly affecttheprocessofcorrosionandtheanti-corrosionlifespanofthepaint film.

The naturalenvironment includes:airtemperature,watertemperature,light exposure,rainfall (including acid rain), average annual wind speed, fog, relativehumidity,water quality(pH value,dissolved oxygen,etc.),and sand content.

The operating conditions are quite complex.Some are in the atmospheric environment(indoors or outdoors),some are underwater(stillwater or flowing water)，some endure the erosion of high and medium speed sediment-ladenwaterflowall yearround,whilesome areconstantlyinastate of alternatingdryandwetconditions.

Wind Power Generation

Wind is a type of natural energy that can be utilized, known as wind energy.Wind energywill notbedepleted like fossil fuels dueto human exploitation,therefore,wind isa renewable energy source.

During the process of converting wind energy into electrical energy, onlythespeed of theairflowisreduced,withoutcausing anypollution to the atmosphere.Usingwindpower can reduce the consumptionof conventionalenergy,therebyreducingtheemissionsofco2andSO2. Thisisof great significanceforprotectingtheenvironment and ecological balance,and improving the energystructure.

Nuclear Power

Withthecontinuousdevelopmentoftheeconomyandthestrengthening of environmental protection awareness,people's demand for efficient, clean,and safe new energy isbecoming increasingly urgent. Nuclearenergy,asacleanand efficientenergysource,isattractingmore andmoreattentionfromdifferentcountries.

Due to the unique environmental conditions and corresponding support systems of nuclear power plants, allthe nuclear power plants currently beingdevelopedandbuilt orabouttobebuilt inourcountry arelocated by the sea.Allequipment and buildings not onlyhave towithstand intensesunlight andweather,but also sufferfrom theerosion of water vapor, salt spray, and sea tide,making them highly susceptible to corrosion.

Corrosion prevention is the most critical issue for nuclear power plants. It not onlyrelatesto thelong-termoperation of equipment andvarious systems,butalsocloselyrelatedtothesafetyofthenuclearpowerplant.

The long-lasting coating protection system not only significantlyextends themaintenancecycle of thecoatingandprolongstheservicelifeofthe entire nuclear power equipment,but alsoplays a crucial role in the safetyoftheentirenuclearpowerstation.

Coal Processing Industry

Asafuelinindustry,coalprovidesalarge amountofenergyforindustrial developmentandtheimprovementofpeople'slivingstandards.Itlaysa solid foundationfor optimizing resource allocation and further promotingeconomicdevelopment.

Themaincharacteristicsof theworkingenvironment inthecoal industry arehumidityandhighoxygenlevels,withbothairandwaterseverely polluted.Therefore,there is a widespread issue of severe electrochemicalcorrosion inmining machinery and equipment.Its corrosionforms mainlyinclude atmospheric corrosion,and there are also wear corrosion,galvanic corrosion,stresscorrosion,pitting,etc.The corrosion conditionsofdifferentregions，differentenvironments，anddifferent equipmentvarygreatly.

Themajorityofcoalproductionrelies onundergroundmining,andthe workingenvironmentdeepundergroundcontainsacertainconcentrationofelectrolytes such as acid,alkali,and salt ingroundwater.Dependingontheregion andtheconditionsof thestrataandrocklayers,the types of salts dissolved ingroundwater and their concentrations,as well as the pH value of the groundwater, can vary greatly.In addition, harmful gasessuchasHzs, S O_{2} \mathsf{N O}_{2} and CH4thatseepout of coal seams can acceleratetherateofelectrochemicalcorrosionofmetals.

The productionlevel and mine design of the coal industry stipulate that the mining lifespan of large and medium-sized mines generally needs to be over50 years,and some even need to exceed 100years,constituting permanentprojects.

The mining workplace is located hundreds of meters underground, where the air is damp,water drips heavily, and corrosion is severe. Replacing and repairing equipment is very difficult, costly, and time-consuming, which seriously affects mine production.This requires that reliable and long-lasting anti-corrosion coatings be used in the design, manufacture, and installation process of mining equipment.
