Description

Technical Field

[0001] This utility model relates to the field of defoamer testing technology, and in particular to a device for testing defoaming and foam-suppressing performance. Background Technology

[0002] In textile dyeing and finishing, a large amount of surfactants are used, making the generation of bubbles in the working bath unavoidable. However, bubbles not only lead to inaccurate metering of the working solution and uneven dyeing and finishing, but more importantly, foam overflow causes the working solution to be lost, polluting the production environment. In severe cases, it can affect the operation of high-temperature jet dyeing machines and overflow dyeing machines, making it impossible for the textile dyeing and finishing process to proceed normally, thus necessitating the use of defoamers.

[0003] Currently, the common methods for testing whether a defoamer meets production requirements are to place the working solution and a certain amount of defoamer in a graduated cylinder and shake them by hand for comparison, or to place the working solution and a certain amount of defoamer in a sealed bottle, fix it on a shaker, shake it, and then compare the results. The former method has the drawback of large testing errors, while the latter method, although simple, cannot simulate the temperature changes of the production environment, and the foam changes need to be monitored continuously during production, which is inconvenient to monitor in a shaking environment.
