| description | The invention discloses a corrosion inhibitor composition, applications thereof, and a method using the same to carry out pickling on equipment. The corrosion inhibitor composition comprises a urea type corrosion inhibitor, a promoter, thiocyanate, a hydrazine type corrosion inhibitor, and inorganic silicate according to a weight ratio of 1:0.25-4:0.25-5:1-8:0.025-0.6. The equipment picking method comprises a step of contacting a pickling solution containing the provided corrosion inhibitor composition with equipment. Through the provided technical scheme, the components in the corrosion inhibitor composition can cooperate with each other to generate a synergetic effect; thus the chemical properties of the corrosion inhibitor composition are stable, and the multi-purpose corrosion inhibitor composition is environment-friendly and is accord with the environment-protection requirements. Furthermore, the adaptability of the corrosion inhibitor composition is strong, the corrosion inhibiting performance is excellent, the addition amount is little, the processing is simple, the effect is prominent, and thus the corrosion inhibitor composition is easy to promote and use. |
