Circulating water carbon steel slow-release agent
Thread Content
I would like to ask everyone: What are the main components of the carbon steel retarders that you use? What are the scale inhibitors and algaecides as well?
The best corrosion inhibitor is zinc ions; adding 2–4 ppm of zinc ions yields a significant corrosion-inhibiting effect.
ZN salts are used in industrial circulating water. For more details, contact Hebei Huarui Lanxing Chemical Building Materials Co., Ltd. at 15094401317
Anions that have a corrosion-inhibiting effect on carbon steel include CrO4 ions, NO2 ions, PO4 ions, SiO3 ions, etc； Cations include Zn2+, Ca2+, Mg2+, Ni2+, Mn2+, etc. Scale inhibitors include polyaspartic acid, polyepoxysuccinic acid, etc. There are many algicides available, such as polyquaternium salts and isothiazolinones. There are many manufacturers on the internet; you can look them up.
Well, all of this is covered in the books. If you are a user, you don’t need to worry about anything; you can use monitoring methods to assess the effectiveness of use. There are standards for slow-release effects, and for scale prevention, you can monitor the heat exchangers, or open the equipment during maintenance to take a look
