How the HT Jigger Dyeing Machine is Cleaned
May 09, 2022
1. To remove oligomers, often use NaOH or pH thiocyanate detergent to wash the tank, and media can also be added to facilitate the melting of oligomers, and high temperature-resistant tackifiers can inhibit oligomers. Precipitation, rapid cooling and high temperature drainage can prevent oligomer deposition and agglomeration.
2. The removal of alkali scale, calcium element and synthetic fiber waste can be cleaned with hydrochloric acid or sulfuric acid. The expected effect is very good, but it has obvious damage to the stainless steel plate (corrosion-resistant stainless steel plate is generally used for the inner wall of the dye vat). The smoothness of the stainless steel plate layer Completely dissipated, the erosion is very large.
3. Removal of condensed dyes, cigarette tar, and grease can be carried out by reducing and cleaning the traditional cylinder making process with hydrosulfite, flaky sodium hydroxide, desulfurizer, etc.
In addition, when cleaning the dye vat, it is necessary to add appropriate waste cloth to the equipment vat to ensure that the rapid water sprayed by the printer nozzle cleans the waste cloth to the "blind spot" that cannot be reached by normal circulation.
