After a long period of use, the high temperature and high pressure soft flow fabric dyeing machine deposits dirt on the inner wall of the cylinder. Especially in the background of the printing and dyeing industry, which generally pays attention to controlling the discharge of sewage, many printing and dyeing factories have caused dyes, oligomers, A large amount of substances such as grease and lint are deposited on the bottom of the tank, and this part of the dirt must be removed in time.
According to the use of the overflow cylinder, the main components of the deposit in the cylinder of the high temperature and high pressure soft flow fabric dyeing machine are different, mainly dust, grease, coagulated dye, dispersant, oligomer, calcium salt, etc. The ingredients are cleaned in different ways.
In normal times, the HTHP soft flow fabric dyeing machine often washes the cylinder with NaOH or acidic sulfite detergent, and can also add the carrier to help dissolve the oligomer. Adding a high temperature resistant dispersant can inhibit the precipitation of the oligomer. Rapid cooling and high temperature drainage prevent the deposition and agglomeration of oligomers.
For the removal of alkali scale, calcium salt and fiber waste in HTHP soft flow fabric dyeing machine, it can be cleaned with hydrochloric acid or sulfuric acid, and the effect is very good. However, it is recommended to use TF-105F clearing agent for stainless steel, which does not contain strong acid. It is not corrosive to the cylinder and the cleaning effect is excellent. In addition, when cleaning the dyeing tank, it is necessary to add an appropriate amount of waste cloth in the cylinder, and the high-temperature and high-pressure soft-flow fabric dyeing machine is to ensure that the high-speed water sprayed from the nozzle is flushed through the waste cloth to a "dead angle" which is difficult to reach in the usual cycle.
