Cleaning of high temperature airflow dyeing machine

1. To remove oligomers, wash the tank with NaOH or acidic sulfite detergent frequently. Adding high temperature resistant dispersant can inhibit the precipitation of oligomers, and rapid cooling and high temperature drainage can prevent the deposition of oligomers. And cohesion.
2. The removal of alkali scale, calcium salt and fiber debris can be cleaned with hydrochloric acid or sulfuric acid. The effect is very good, but it has a significant impact on stainless steel (corrosion-resistant stainless steel is generally used for the inner wall of the dyeing tank).
3. Removal of agglomerated dyes, tars, and greases can be reduced and cleaned by traditional tank preservation technology with sulphuric acid powder, liquid caustic soda, and emulsifiers.
