How to correctly determine the amount of different types of defoamers to be added
For actual industrial production, different types of pharmaceutical products have outstanding effects, but if the correct use of the products is not mastered, it is difficult to exert the actual effects of the products. This is the case for defoamers. In the actual use of the products, the amount of product addition should be understood.
However, in real production and life, due to the variety of defoamer products, the performance and actual effectiveness of the products are also very different, so this requires users to master the correct addition and use methods of different pharmaceutical products. Let’s listen to the experts in the professional research and development and production of defoamers to make a detailed introduction.
At present, the use of defoamers is very common. In life and industrial production, it can be added to achieve the purpose of suppressing or eliminating foam. It can improve production capacity, reduce unnecessary waste of raw materials, shorten the reaction cycle, ensure the accuracy of measurement, protect the environment, and reduce the occurrence of accidents.
However, before the product is used, the product performance of the defoamer needs to be tested. The performance of the product that needs to be tested mainly includes defoaming rate, defoaming ability, anti-foaming ability, storage stability, water solubility, acid and alkali resistance, physiological toxicity, high temperature resistance and optimal usage. Usually the most important are defoaming performance and antifoaming performance, and different industries have different performance requirements for defoamers.
According to the different chemical components, we can divide defoamers into alcohol defoamers, fatty acid and fatty acid ester defoamers, amide defoamers, phosphoric acid defoamers, etc. For these different types of defoamers, the addition amount of their products is mainly as follows:
1. Amine defoamers are mainly used in fiber processing, and the addition amount is 0.02-2%.
2. Polyether defoamers are more commonly used in paper printing and dyeing, and cleaning, and the addition amount is generally 0.025-0.25%.
3. When alcohol defoamers are used, the dosage is generally within 0.01-0.10%.
4. Amide defoamers have better effects, and the addition amount is generally within 0.002-0.005%.
5. Phosphoric acid defoamers are most commonly used in fibers and lubricating oils, and the addition amount is between 0.025-0.25%.
6. The addition amount of oil defoamers is between 0.05-2%, and the addition amount of fatty acid ester defoamers is between 0.002-0.2%.
In addition, experts recommend that some necessary product performance tests be conducted before using defoamers. Different performances of defoamers require different test methods, but there are many ways to test defoaming and antifoaming properties, and any defoamer must be tested. The most commonly used test methods are the West German Industrial Standard Method, the aeration method, the aeration method, the titration method, etc.
