1. Removal of oligomers, often with NaOH or acidic sulfite detergent, can also be added to the carrier to help dissolve the oligomer, adding high temperature resistant dispersant can inhibit the precipitation of oligomers, Rapid cooling and high temperature drainage prevent the deposition and agglomeration of oligomers.
2. The removal of alkali scale, calcium salt and fiber waste can be cleaned with hydrochloric acid or sulfuric acid. The effect is very good, but it has obvious influence on stainless steel (corrosion-resistant stainless steel is generally used on the inner wall of dyeing cylinder). The chrome layer gloss disappears completely and the corrosion is very Big. It is recommended to use the transferred TF-105F cleaning agent, which does not contain strong acid, is not corrosive to the cylinder, and has excellent cleaning effect.
3. The condensation of condensed dyes, tars and greases can be reduced and cleaned by using the traditional cylinder-preserving process with insurance powder, liquid alkali and emulsifier.
