The main purpose of water treatment is to prevent corrosion of metal components in the water system, avoid scale formation, and control the growth of microorganisms (such as bacteria and algae). This process works by adding specific chemicals to the water that are able to interact with certain components of the water to achieve the desired effect.
Central air conditioning water treatment agent
1. Corrosion inhibitor
A corrosion inhibitor is a substance capable of forming a protective film on the surface of a metal that prevents the metal from coming into direct contact with water or other aggressive substances, thereby slowing or preventing corrosion from occurring. It works by inhibiting the release of metal ions or blocking dissolved oxygen from reaching the metal surface, effectively extending the service life of the equipment.
2. Scale inhibitor
Scale inhibitor is mainly used to prevent calcium magnesium and other hardness ions from precipitating to form hard scale. They use chelation to stabilize these scale-prone ions in solution, or change the crystalline form to make them less likely to adhere to the pipe wall. In addition, for the small amount of sediment that is already present, some scale inhibitors also have a certain dispersion ability, helping to keep the flow of water unimpeded.
3. Pre-film agent
The role of the pre-film agent is to quickly establish a dense and uniform anti-corrosion film inside the newly installed or cleaned heat exchanger and pipeline. The membrane can not only provide immediate protection, but also provide a good basis for other types of corrosion inhibitors added during long-term operation.
4. Scale remover
When the system has accumulated more difficult to remove dirt, it is necessary to use specially designed detergent to clean. These products usually have strong acid-alkaline or organic solvent properties, which can effectively dissolve and peel away the accumulated old scale layer and restore equipment performance.
5. Bactericidal algaecide
In order to control the growth and reproduction of various harmful organisms that may exist in the water body, it is very necessary to add bactericides and algaecides regularly. Such agents mainly include oxidizing and non-oxidizing two categories, the former such as chlorine gas, sodium hypochlorite, etc., the latter covers a variety of high-efficiency and low-toxicity products such as quaternary ammonium compounds. Correct selection and timely adjustment of its concentration is very important to ensure the safety of water quality.
