Antifoam, similar to defoamer, is a chemical additive to deal with the foam problem of industrial production. However, there is still a certain difference between it and defoamer, as for the difference, I will talk to you about it today.
The difference between an antifoam agent and a defoamer.
The main difference between an antifoam and a defoamer is the way and mechanism of use, the antifoam is mainly used to prevent the formation of foam, while the defoamer is mainly used to eliminate the foam that has been generated.
Foam inhibitors and defoamers are both surfactants that are used to control bubbles and foam in liquids, but they have different mechanisms of action.
Foam suppressants are usually added to a small amount of liquid to inhibit the formation of bubbles by reducing the surface tension of the liquid, thereby preventing the formation of foam.
Defoamers, on the other hand, add a certain amount to the surface of the liquid to eliminate the foam that has been produced by reducing the surface tension of the liquid or destabilizing the foam.
In practical applications, the appropriate antifoam or defoamer should be selected according to different liquids and needs.
Features of defoamers:
Defoamers can eliminate foam mainly by reducing the surface tension of liquids such as water, solutions and suspensions. It has the effect of defoaming and foaming at the same time, which can clean the foam after it has formed, and can also prevent the formation of foam.
Features of antifoam:
The role of antifoam agent is mainly reflected in the foam inhibition and prevents the formation of foam. For foam that is already present, the treatment effect may not be as significant as that of a defoamer.
Here are some commonly used sample composition analysis workflows:
1.Sample preparation: Representative samples are selected and the necessary pretreatments, such as sample grinding, dissolving, dilution, etc., are performed to ensure representativeness and operability of the analysis.
2.Analysis methods: Infrared spectroscopy, nuclear magnetic resonance spectroscopy, GC-MS, PY-GC-MS, ICP, IC, HPLC, XPF, GPC and other instruments are generally used.
3.Instrument testing: According to the selected analysis method, prepare and debug the corresponding instrument equipment, and calibrate and calibrate to ensure the accuracy and stability of the instrument.
4.Sample measurement: Combined with the analysis of the map, combined with the common methods of basic chemistry and the verification of related characteristics, the analysis results are verified in many aspects.
5.Data processing: Data processing is performed on the measured raw data, such as peak identification, peak area or peak height integration, etc., to obtain quantitative results for each component.
6.Result report: Based on the results of the analysis, the composition of the measured substance is evaluated and interpreted, its content, purity or different relevant indicators are determined, and a report is written.
Through component analysis, the analysis technology can guide the improvement of product processing technology, optimize the proportion of product ingredient formulation, and study the mixing performance of different substances. The qualitative and quantitative analysis of material composition by using spectroscopy, chromatography, energy spectroscopy, mass spectrometry, thermal spectroscopy and other analytical instruments can bring a series of benefits such as improving ingredient formulation, improving process, changing product performance, and reducing costs for social enterprises.
