LP-Z302 Iron residual temperature blackening agent

2018/07/06

Foreword
Steel waste temperature blackening agent is to use the heat of the workpiece to temper the waste heat, according to the thermal polymerization reaction mechanism to form a black polymer material protective film, to achieve the purpose of rust and corrosion. The process is environmentally friendly, energy-saving, high-efficiency, and has a good blackening effect and high gloss. It is a substitute for traditional alkaline blackening.

Application 
Steel blackening agent can blacken cast iron, various carbon steel, alloy steel, and powder metallurgy and other mechanical parts. Widely used in standard parts, chains, springs, railway equipment and other steel parts and components industries.
  three. product advantages
1. Water is used as solvent, environmental protection and safety;
2. It is matched with the heat treatment furnace production line, which is highly efficient and energy saving;
3. After blackening, the workpiece has gloss, corrosion resistance and strong rust resistance;
4, no need to rinse after blackening, no waste discharge, reduce labor intensity and improve the production environment;
5. There is no hydrogen embrittlement in blackened workpieces.
6. Process flow
Quenching tank → cleaning → tempering furnace (temperature 350 ° C-500 ° C or higher) → blackening → drying → dipping anti-rust oil

 Instructions
1. Iron and steel blackening agent is a concentrated type. Stir it evenly before use. The blackening agent is fully mixed with water at a ratio of 3-5 to become a working fluid.
2, heating the non-corrosive parts to 250 ° C-500 ° C can put into the blackening working fluid, the blackness instantly;
3, hot air drying and packing (oiling) after the parts are out of liquid;
4. The working temperature of the blackening working solution is best in the range of (40 ° C-60 ° C);
5. Add blackening agent according to production volume.

 Packaging and storage
This product is packed in plastic drums, 25Kg / drum, stored at room temperature, valid for one year.
