What are the applications of alkaline cleaning agents?

Metal Cleaning

Steel Products: Effectively removes oil, grease, dust, and light rust from steel surfaces, providing excellent surface conditions for subsequent processing such as painting, electroplating, and heat treatment. It prevents impurities like oil from affecting processing results, improving the adhesion and corrosion resistance of coatings or plating.

Copper and Copper Alloys: Safely cleans oil and oxides from copper surfaces without significant corrosion, maintaining a bright finish. For example, copper statues, copper crafts, and copper pipes can be regularly cleaned and maintained with alkaline cleaning agents.

Aluminum and Aluminum Alloys (in some cases): Under appropriate concentration and conditions, alkaline cleaning agents can be used to clean oil and some naturally formed oxide films from aluminum and aluminum alloy surfaces. However, avoid high concentrations or prolonged contact to prevent corrosion. For example, aluminum parts in car engines and aluminum alloy windows can be cleaned with mild alkaline cleaning agents for daily cleaning.

Industrial Equipment Cleaning

Machinery Equipment: Machines such as lathes, milling machines, and drilling machines accumulate cutting fluids, lubricating oils, and metal debris during processing. Alkaline cleaning agents quickly break down oil and remove impurities, ensuring normal operation and precision.

Food Processing Equipment: Effectively removes oil, food residue, and bacterial contamination from food processing equipment without causing corrosion, while meeting food safety standards. For example, bread ovens, meat processing equipment, and dairy production equipment can be regularly cleaned with alkaline cleaning agents to ensure cleanliness and prevent food contamination.

Petrochemical Equipment: Used to clean oil, grease, and carbon deposits from the inner surfaces of pipelines, reactors, and storage tanks in the petrochemical industry. Alkaline cleaning agents break down and remove these stubborn oils and carbon deposits through saponification and emulsification, ensuring normal operation and improving heat transfer efficiency and production efficiency.

Daily Household Cleaning

Kitchen Supplies: Range hoods, stoves, and cookware accumulate significant oil. Alkaline cleaning agents quickly break down oil for easy wiping. They are also effective on oil stains on kitchen tiles and floors.

Clothing: Alkaline cleaning agents effectively remove stubborn stains like oil and blood from clothing. They are commonly used in industrial laundries for items like hotel linens and restaurant uniforms that frequently encounter oil.

Home Surfaces: Can be used to clean dust and oil from furniture, bathroom tiles, and fixtures. For example, oil stains on wooden furniture can be wiped clean with diluted alkaline cleaning agent, and stains on toilet bowls and ceramic bathroom fixtures can be effectively removed with alkaline cleaning agent.

Other Fields

Textile Industry: Used in pre-treatment processes to remove natural impurities, sizing agents, and oil from fabrics, improving water absorption and dyeing performance. This allows fabrics to better absorb dyes and auxiliaries in subsequent dyeing and finishing processes, resulting in uniform, vibrant colors and a pleasant feel.

Electronics Industry: In the production of electronic components, alkaline cleaning agents can be used to clean oil, solder flux residue, and other impurities from electronic parts, ensuring performance and reliability. However, for sensitive components, specially formulated alkaline cleaning agents that do not corrode electronic components should be used, and the cleaning process and parameters should be strictly controlled.

Building Exterior Cleaning: For building exteriors made of brick, concrete, or tile, alkaline cleaning agents can remove dust, oil, mildew, and some acidic pollutants, restoring a clean and attractive appearance. During cleaning, the alkaline cleaning agent is usually diluted to an appropriate concentration based on the material and level of contamination of the exterior wall, and professional cleaning equipment and processes are used.
