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 during 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 aggregation.
The removal of alkali scale, calcium salt and lint can be cleaned with hydrochloric acid or sulfuric acid, which has a good effect, but it has obvious effects on stainless steel (corrosion-resistant stainless steel is generally used for the inner wall of the dyeing vat), and the luster of the chrome plating layer disappears completely, which is very corrosive. It is recommended to use Transfar's TF-105F tank cleaning agent, which does not contain strong acid and is not corrosive to the tank body, and the tank cleaning effect is very good.
Condensed dyes, tar, and grease can be removed by reducing and cleaning with traditional cylinder protection technology using hydrosulfite, liquid alkali, and emulsifiers.
In addition, when cleaning the dyeing vat, it is necessary to add an appropriate amount of waste cloth to the machine vat to ensure that the high-speed water sprayed from the nozzle is washed through the waste cloth to the "dead corner" that is difficult to reach normally.
