Introduction Name:Sodium Nitrite Formula:NaNO2 CAS No:7632-00-0 Assay:99% Application 99% Crystal Sodium Nitrite is an oxidant corrosion inhibitor,suitable for low hardness or ultra-low hardness water treatment.This product is toxic, so it is mainly used in closed circulating cooling water system, is a dangerous corrosion inhibitor, when the use concentration is insufficient, not only no corrosion inhibition, but accelerate corrosion, the use concentration is usually 300 500mg/L. The optimal pH range of water quality is 8 10, so it is often used together with 300 600mg/L Na2CO3. Water quality pH< At 6, decomposition, no inhibition effect. Often mixed with sodium molybdate, on the one hand synergistic effect, on the other hand to reduce the dosage of both. Black gold only.It is antirust, ineffective to copper and other non-ferrous metals, and even corrosive. Packing 25KG PP/PE or according to client's request.
