Antifoam agent is a kind of chemical additives with defoaming effect, which is widely used in the industrial field, and even involved in the food industry. The common application of defoamer makes many processes in the industry more convenient, saves a lot of time and money costs, and greatly improves the production efficiency of various industries. I have already told you how to choose a suitable defoamer before, after choosing a good defoamer we will use it. But after use, some people will appear defoamer effect is not significant problem, today I will explain to you the effect of defoamer use what are the reasons.
1.The performance of the defoamer itself, some of the defoamer's own original defoaming effect is not good, foam inhibition time is not long-lasting, resulting in defoamer can not achieve the desired effect of defoaming, even if it is achieved there will be a second foam generation; 2.The defoamer additive amount of the problem, defoamer in the addition, add the amount must be appropriate, add the amount of less than the ideal antifoaming effect can not be achieved, add more than a waste of cost, not to mention that the defoamer may be difficult to dissolve and thus inhibit the defoamer's original defoaming effect; 3.The defoamer adding method, defoamer adding method has a variety of one-time addition, subaddition, continuous addition. Specifically to choose which add method, according to the existing use of the environment, after the test, and then add; 4.Defoamer dilution, generally in the dilution of defoamer is not recommended to add water directly for dilution, because water will destroy the original molecular structure of the defoamer, resulting in the emergence of delamination, emulsion and other problems, thus affecting the defoaming effect of the defoamer; 5.The use of defoamer temperature problems, each kind of defoamer has its own temperature range, in the use of the temperature range should be strictly in accordance with the use of this temperature range, if out of range, the effect of defoamer will also be affected; 6.Defoaming failure of the problem, defoamer should be used within the shelf life, expired defoamer effect will be affected, and like food defoamer, if the expiration date of the defoaming effect will not only be affected, but also may have toxic substances, which will endanger the health and safety of human life.
