Seadei 1806 is a multi-purpose corrosion inhibitor and scale inhibitor that complies with electrical standards. It is mainly used to control scaling and corrosion in circulating water systems and has an efficient scale inhibition and corrosion inhibition effect. The main components are HEDP, HPMA, PBTCA, a tetra-component copolymer, and zinc sulfate heptahydrate, which are combined.
The distinctive feature of this agent is that it is suitable for circulating cooling water with high hardness, high alkalinity, high temperature, and high pH value. The presence of high chloride ions and trivalent iron ions has little effect on this agent. The recommended usage concentration is generally 30-50 mg/L. No adjustment of pH value is required. It is convenient to use and has a very wide range of applications.
