Anion resin latest offer, cationic resin manufacturers. Central air conditioning refrigeration unit cleaning agent is circulating cooling water and chilled water system for cleaning agents, cleaning method which overcomes the shortcomings and deficiencies, the refrigeration unit's security, stability, economic and long-term operation provides a reliable technical support . A central air conditioning cleaning agent full account of the user's specific situation, the main cleaning agent, biocide agents, dispersing penetrant and efficient corrosion inhibitors and other organic compound made of organic cleaning agents, when used without adding any aid agents, simplify and facilitate the cleaning of the installation and operation site; 2 inhibition efficiency, clean and fast, easy cleaning waste water treatment, in favor of the pre-cleaned copper material film; 3 can inhibit copper in pickling process copper alloy - steel composite parts galvanic corrosion; anti-Fe3 +, Cu2 + accelerated corrosion ability; 4. central air conditioning cleaning agent used for cleaning cleaning the main agent for the organic series of safety equipment, cleaning thorough, corrosion rate; basically the operating personnel is not corrosive, toxic, simple operation, safe and reliable; same time, the product does not contain toxic substances, by simple neutralization can be discharged after treatment, safety and environmental protection. Products using solid components, safe and easy to use, no harm to human body, no corrosion of equipment, had no effect on the environment; 5 with air conditioning, cleaning module supporting the use of cleaning quality assurance, reduce labor intensity, is conducive to the user's direct use and for regular cleaning and maintenance of air conditioning equipment, saving equipment maintenance expenses; 6 in the cleaning process, H + will cause corrosion of the metal body, and the emergence of hydrogen embrittlement, so cleaning agent to be added to the corresponding inhibitor; dissolved generated Fe3 + , Cu2 + and other oxidizing metal ions cause pitting of the body, copper and so on, so the cleaning fluid need to join a masking agent.
