How to clean high temperature and high pressure overflow dyeing machine
Mar 06, 2022
1. Removal of oligomers, high temperature and high pressure dyeing machines often use NaOH or acid sulfite detergent to wash the tank, and a carrier can also be added to help the dissolution of oligomers, and the addition of high temperature-resistant dispersants can inhibit oligomers The precipitation, rapid cooling and high temperature drainage can prevent the deposition and agglomeration of oligomers.
2. 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). Big. 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 an excellent cylinder cleaning effect.
3. The removal of condensed dyes, tars and oils can be carried out by reducing and cleaning by using the traditional tank protection process with hydrosulfite, liquid caustic soda and emulsifiers.
In addition, when cleaning the dye vat, it is necessary to add an appropriate amount of waste cloth into the machine cylinder. 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 difficult to reach in normal circulation.
