How to clean the high temperature and high pressure overflow dyeing machine?

1. For the removal of oligomers, the tank is often washed with NaOH or acid-base sulfite detergent. Plasmid carrier can be added to facilitate the dissolution of oligomers. The addition of heat-resistant thickener can inhibit the precipitation of oligomers, and the rapid temperature reduction and high-temperature effluent can avoid the accumulation and cohesion of oligomers.
2. The removal of alkali scale, calcium salt and chemical fiber debris can be cleaned with sulfuric acid or hydrochloric acid. The actual effect is very good, but it has significant harm to the stainless steel plate (corrosion-resistant stainless steel plate is widely used in the inner cavity of the dye vat). The gloss of the stainless steel layer has completely disappeared, and the corrosion is very large. It is proposed to use tf-105f cylinder cleaning agent, which has no strong alkali and no corrosion to the engine cylinder block. The actual effect of cylinder cleaning is very good.
3. For the removal of cohesive dyes, nicotine and vegetable oils, the traditional cylinder protection processing technology can be used to carry out restoration and cleaning with insurance powder, liquid alkali, asphalt emulsifier, etc.
On the other hand, when cleaning the dye vat, an appropriate amount of waste cloth must be added to the tank body to ensure that the high-speed water sprayed by the nozzle is washed through the waste cloth to the "blind area" that cannot be reached by the normal circulation system.
