Application scenarios of acidic cleaning agents

Acidic cleaning agents, due to their strong stain removal and sterilization properties, are widely used in various fields, including industry, households, and medicine. The following are specific applications:

Industrial Applications

Metal processing: In the processing of metal products, acidic cleaning agents can be used to remove rust, oil stains, and scale from metal surfaces. For example, steel mills use acid pickling on hot-rolled steel sheets to remove the surface oxide layer, improving the surface quality of the steel and preparing it for subsequent processing and coating.

Equipment cleaning: Industrial equipment such as boilers, heat exchangers, and reactors will accumulate scale and dirt over time, affecting equipment performance and efficiency. Acidic cleaning agents can effectively dissolve this scale and dirt. For example, power plants regularly clean boilers with acidic cleaning agents to improve heat transfer efficiency, reduce energy consumption, and extend equipment life.

Pre-treatment for electroplating and coating: To ensure the adhesion between the electroplated or coated layer and the metal substrate, the metal surface must be thoroughly cleaned before electroplating or coating. Acidic cleaning agents can remove oil stains, rust, and impurities from the surface, achieving good cleanliness and roughness, and improving the quality of electroplating and coating.

Household Applications

Bathroom cleaning: Toilets, drains, and tiles in bathrooms are prone to scale, stains, and bacterial growth. Acidic cleaning agents can effectively remove scale and stains, kill bacteria, and keep the bathroom clean and hygienic. For example, using acidic cleaners containing hydrochloric acid or citric acid to clean toilets can quickly remove dirt and stains from the toilet bowl.

Kitchen cleaning: Stoves, range hoods, and sinks in the kitchen often get oily stains and scale. Acidic cleaning agents can break down oil stains and remove scale, restoring kitchen appliances to cleanliness. For example, wiping kitchen sinks with acetic acid or citric acid solution can remove water stains and dirt, making them shine.

Medical Applications

Cleaning medical instruments: Some medical instruments, such as surgical instruments and dental instruments, will be contaminated with blood, tissue fluid, and bacteria after use. Acidic cleaning agents can effectively remove these contaminants and have a certain bactericidal effect, ensuring the cleanliness and hygiene of the instruments. However, it is necessary to choose mild, residue-free acidic cleaning agents that meet medical standards to avoid corrosion of the instruments or harm to the human body.

Hospital environmental cleaning: Hospital wards, operating rooms, and bathrooms require regular cleaning and disinfection. Acidic cleaning agents can be used to clean stains and bacteria from the surfaces of floors, walls, and furniture, creating a clean and hygienic medical environment. For example, wiping hospital ward floors with a dilute acetic acid solution can remove stains and provide a certain level of disinfection.

Food Processing Applications

Equipment cleaning: Food processing equipment such as storage tanks, pipelines, and evaporators will retain food residue and dirt during production, easily breeding bacteria. Acidic cleaning agents can effectively remove this dirt and have a bactericidal effect, ensuring that the equipment meets food hygiene standards. For example, citric acid solution is often used to clean food processing equipment, as it removes dirt without contaminating food.

Fruit and vegetable cleaning: In fruit and vegetable processing, acidic cleaning agents can be used to remove pesticide residues, wax, and dirt from the surface of fruits and vegetables. For example, soaking fruits in a dilute hydrochloric acid or acetic acid solution can effectively remove surface impurities and some pesticide residues, improving the cleanliness and safety of fruits and vegetables.
