水处理与水质管理
Water treatment and water quality management
水处理原理：在中央空调冷却水系统和冷冻水系统经常投加各种中央空调水处理药剂 ，如缓蚀阻垢剂、分散剂、杀菌剂，使水中的结垢性离子稳定在水中，其原理是通过螯合、络合和吸附分散作用，使钙镁离子稳定地通过螯合物络合溶于水中，并对氧化铁、二氧化硅等胶体有良好的分散作用。
Principle of water treatment: a variety of central air conditioning water treatment chemicals are often added to the cooling water system and chilled water system of the central air conditioning For example, corrosion and scale inhibitor, dispersant and bactericide can stabilize the scaling ions in the water. The principle is to make calcium and magnesium ions stably dissolve in the water through chelate, complexation and adsorption dispersion, and have good dispersion effect on colloids such as iron oxide and silicon dioxide.
水处理药剂：水处理清洗药剂加入仪器的水循环系统中，药剂分为：缓蚀剂、阻垢剂、预膜剂、除垢剂和杀菌灭藻剂。
Water treatment agent: the water treatment cleaning agent is added to the water circulation system of the instrument. The agent is divided into corrosion inhibitor, scale inhibitor, pre membrane agent, scale remover and bactericide and algaecide.
缓蚀剂：可起到控制腐蚀、保护机组的作用在金属表面形成不溶于水或难溶于水的保护膜，阻碍金属离子的水合反应或溶解氧反应，从而抑制腐蚀反应；
Corrosion inhibitor: it can control corrosion and protect the unit to form a water-insoluble or water-insoluble protective film on the metal surface, and prevent the hydration or dissolved oxygen reaction of metal ions, so as to inhibit the corrosion reaction;
阻垢剂：可防止结垢。
Scale inhibitor: can prevent scaling.
预膜剂：使水系统中的所有换热设备与管道的金属内表面形成一层非常薄的能抗腐蚀的保护膜。本文来源：制冷百科公众号hvacrbk。

除垢剂：使水中的结垢性离子稳定在水中，其原理是通过螯合、络合和吸附分散作用，使钙镁离子稳定地通过螯合物络合溶于水中，并对氧化铁、二氧化硅等胶体有良好的分散作用。
Scale remover: it can make the scaling ions in water stable. Its principle is to make the calcium and magnesium ions stably dissolve in water by chelating, complexation and adsorption dispersion, and has good dispersion effect on colloids such as iron oxide and silicon dioxide.
杀菌剥离剂：可杀灭并防止微生物、藻类生成。
Bactericide stripping agent: it can kill and prevent the formation of microorganisms and algae.
