High temperature overflow dyeing machine will deposit dirt on the inner wall of the cylinder when it is used for a long time. Especially in the background of printing and dyeing industry, the printing and dyeing industry generally pays attention to controlling the discharge of sewage. Many printing and dyeing factories use dyes, oligomers, A large amount of substances such as grease and lint are deposited on the bottom of the cylinder.
The consequence is that the dyeing tank will rise and cool down slowly, and there will be a flying point during dyeing. Seriously, the dyeing equipment will be blocked and the dyeing temperature will not rise. Depending on the application of the overflow tank, the main components of the deposits in the cylinder are also different, mainly dust, grease, coagulated dyes, dispersants, oligomers, calcium salts, etc., which are cleaned according to different ingredients.
High-temperature overflow dyeing machine for the removal of oligomers, high-temperature and high-pressure dyeing machines often use NaOH or acidic sulfite detergent to wash the cylinder, can also be added to the carrier to help dissolve the oligomer, add high temperature resistant dispersant can Inhibition of oligomer precipitation, rapid cooling and high temperature drainage prevent oligomer deposition and agglomeration.
The removal of alkali scale, calcium salt and lint from high-temperature overflow dyeing machine can be cleaned with hydrochloric acid or sulfuric acid, and the effect is very good, but it has obvious influence on stainless steel (corrosion-resistant stainless steel is generally used on the inner wall of dyeing cylinder), and the chrome layer gloss disappears completely. Very corrosive. It is recommended to use the transferred TF-105F cleaning agent, which does not contain strong acid, is not corrosive to the cylinder, and has excellent cleaning effect.
