**The chemicals involved in the cleaning process of the air conditioning water system mainly include:
* Air conditioner cleaner.
1.Cleaning agent:
Slime stripper: Used to remove biological slime and organic impurities deposited within the system, by destroying the slime structure to make it easy to discharge.
Pickling agents: such as hydrochloric acid, citric acid, nitric acid, etc., used to dissolve scale and rust products, especially effective for carbonate scale and rust.
Caustic lotions: such as sodium hydroxide, etc., used to remove organic matter such as grease and protein, as well as some inorganic scales.
Complexation cleaner: less corrosive to metals, can form a stable complex with metal ions, and helps to remove insoluble scales.
The cleaning process is generally carried out in several steps, including pre-rinsing, chemical cleaning (pickling or caustic washing), rinsing and neutralization.
For water quality stabilization treatment, the main chemicals used are:
1.Corrosion inhibitors:
It can form a protective film on the metal surface, reducing the chance of direct contact between water and metal, thereby preventing or delaying metal corrosion. These include organic phosphonates, azoles, amines, etc.
2.Antiscalants:
It can prevent the formation of scale by calcium, magnesium ions and silicates in water, such as polyphosphate, copolymer, sulfonate, etc., and prevent the formation of scale through chelation, dispersion, lattice distortion, etc.
3.Biocides (also known as fungicides, algaecides):
Inhibits and kills microorganisms in the water system, including bacteria, fungi, algae, etc., such as chlorine preparations, bromine preparations, isothiazolinone and quaternary ammonium salts.
4.Dispersants:
Helps existing fine particles to maintain uniform dispersion in the water, preventing particle agglomeration and further deposition.
In daily operation, water quality stabilizers are usually regularly put into the circulating water according to the set time interval or monitoring data to keep the water system clean, free of scale and biological pollution, and ensure the efficient and safe operation of the equipment.
