In industrial production, the evaporation crystallization process is widely used. However, the generation of foam in this process often becomes a bottleneck in production efficiency. To do this, we can choose to include the appropriate amountEvaporation crystallizationDefoamerto dynamically eliminate those floating or suspended foams, and better protect the service life and resource environment of the equipment. So, what are the performance tests and dosing concentrations of evaporation crystallization defoamers?Today, I will explain the relevant knowledge in detail for you, I hope it will be helpful to you.
1. Performance test of evaporation crystallization defoamer
1.During the evaporation crystallization process, the rapid elimination of the foam that has already been produced is the first task of the defoamer. Through comparative experiments, the elimination effect of the defoamer on the foam at different time points can be observed, so as to evaluate the defoaming rate.
2.Evaporative crystallization defoamers must not only be able to defoam quickly, but also be able to inhibit foam regeneration for a long time. This performance can be tested by continuously observing the foam changes in response to the evaporation crystallization defoamer.
3.In the process of evaporation crystallization, the evaporation crystallization defoamer should have good compatibility with other chemicals to avoid chemical reactions that lead to performance degradation or negative effects. Therefore, defoamers need to be tested for compatibility.
4.The evaporation crystallization process often needs to be carried out under high temperature conditions, so the high-temperature performance stability of evaporation crystallization defoamers is crucial. By testing under simulated operating conditions, the performance of the defoamer in a high-temperature environment can be evaluated.
2. The dosing concentration of evaporation crystallization defoamer
1.Effect of concentration on defoaming effect:The right dosing concentration is the key to achieving the best performance of evaporative crystallization defoamers. Too low a concentration may not achieve the desired defoaming effect, while too high a concentration may lead to unnecessary waste or a negative effect on the system. Therefore, it is necessary to determine the ideal dosing concentration based on the experimental results.
2.Adjustments in practical applications:In the actual production process, due to changes in process conditions, water quality and other factors, it may be necessary to adjust the dosing concentration of evaporation crystallization defoamer in a timely manner. The operator should pay close attention to the foam in the evaporation and crystallization process, and flexibly adjust the concentration according to the actual situation to maintain a stable defoaming effect.
