You should know that different foaming systems require different defoamers. For example, the temperature of the foaming system will affect the use of defoamers. In a high-temperature foaming environment, the use of ordinary defoamers may cause the defoaming effect to fail because the temperature is too high. In this case, special products should be used. The high temperature resistant defoamer too.
The emergence of high temperature resistant defoamers is mainly due to the fact that in the past foam problem handling process, sometimes the ambient temperature where foam occurs is relatively high. When ordinary defoamers are used, the defoaming effect will be invalid due to the high temperature state, and it may also In order to solve the problem of defoaming under high temperature conditions, high temperature resistant defoamers have appeared.
High temperature resistant defoamer is made by special process polymerization of fatty alcohols, amides, polyethers, hydrocarbons, etc. It has the advantage of being able to quickly penetrate into the liquid and spread out quickly, in addition to a variety of surface activities. The stubborn foam produced by the agent can stably defoam under strong alkali and high temperature.
High temperature resistant defoamer is used in the pulping, papermaking, coating process, industrial cleaning, degreasing agent, metal grinding fluid, cutting fluid, coating, chemical fiber oil, adhesive, water-based ink, agriculture, chemical industry in the paper industry , Sewage treatment, knitting oil, ore washing. It can also be used for medium defoaming in large, medium and small ethylene plants.
The high temperature resistant defoamer has the same defoaming ability as the ordinary defoamer, and is more excellent in defoaming speed, and can be applied in a wide range of industries. Of course, the most outstanding point of the high temperature resistant defoamer is its high temperature resistance. Under high temperature conditions, its own defoaming ability will not be compromised, and it can maintain the foam suppression effect for a long period of time. The chemical stability of the high temperature resistant defoamer is very good, and the phenomenon of oil floating and demulsification will not occur at high temperature.
When encountering foaming problems in high temperature environments, high temperature resistant defoamers are undoubtedly the best choice.
High temperature resistant defoamer is made by special process polymerization of fatty alcohols, amides, polyethers, hydrocarbons, etc. It can quickly penetrate into the foam and destroy the stability of the foam, thereby achieving the effect of defoaming.
In addition, high temperature resistant defoamers can be used in high temperature foaming systems, and the effect will not be compromised. This is a major feature superior to ordinary defoamers.
High temperature and strong defoaming agent, high temperature resistance and strong acid and alkali resistance. There are two types of liquid and powder. It has high defoaming power at very low concentration, high shear and a wide range of PH values (2-14), It is stable under high temperature (250℃) and can be used for water-based and oily system defoaming. The use temperature must be above 80℃. The higher the temperature, the higher the efficiency and the better the effect. It can be used to defoam and suppress foam in high temperature and strong acid-base media under various extreme conditions such as bottle washing additives and oilfield drilling.
