Cleaning method of high temperature and high pressure dyeing machine

The high temperature and high pressure dyeing machine should be cleaned after use. Long-term use will produce deposits on the inner wall of the cylinder, which affects the use of the high temperature and high pressure dyeing machine in the dyeing process, and may affect the quality of dyed fabrics.

High temperature and high pressure dyeing machines often use NaOH or acidic sulfite detergent to wash the tank to remove oligomers. Carriers can also be added to facilitate the dissolution of oligomers. Adding high temperature-resistant dispersants can slow down the precipitation of oligomers. Rapid cooling and high temperature drainage also prevent oligomer deposition and agglomeration.

?The removal of alkali scale, calcium salt and lint can be cleaned with hydrochloric acid or sulfuric acid, and 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 dye vat). It is recommended to use Transfar's TF-105F cylinder cleaning agent, which does not contain strong acid, is not corrosive to the cylinder body, and has a good cleaning effect.

?The removal of agglomerated dyes, tars, and greases can be carried out by reducing and cleaning with hydrosulfite, liquid caustic soda, emulsifiers, etc.

In addition, when cleaning the dye vat, it is necessary to add an appropriate amount of waste cloth into the machine vat. The high temperature and high pressure dyeing machine ensures that the high-speed water sprayed from the nozzle is washed through the waste cloth to the "dead corner" that is usually difficult to reach.
