1. Customer information: Azerbaijan Lier Electronics, Nanhui's cleaning agent and defoaming agent use terminal, the cleaning agent and defoaming agent provided by the original defoaming agent supplier affects the transparency of the cleaning agent product, and the foam suppression effect is not very satisfactory. So I turned to Nanhui, a defoamer manufacturer.

3. Customer requirements: the defoamer must not affect the transparency, and there must be no residue. After diluting the cleaning agent with defoamer added according to cleaning agent: water=1:9, look at the defoaming and anti-foaming effects.
Principle and analysis of defoaming
1. Analysis of the cause of blistering:
Both liquid laundry detergent and powder detergent are laundry detergents, which are composed of surface active agent (SAA) and a large amount of auxiliary agents. When shaking and stirring, a large amount of foam is generated and is difficult to burst. In detergents, anionic and nonionic surfactants are generally contained. Amphoteric surfactants and cationic surfactants are also used in special applications. It can be said that surfactants are the most important ingredients in detergents. However, it The presence of it also leads to undesirable excessive foam during the washing process. Therefore, it is necessary to consider the appropriate amount of defoamer ingredients in the detergent formulation, which does not affect the detergent effect and the foam elimination is ideal, and the product is of higher quality.
2. The hazards of blistering:
①For multi-voided washing products, such as fiber products, too much foam is not easy to rinse, and the rinsing time needs to be extended, and the rinsing cost is added.
②Foam overflows the cleaning system, causing environmental pollution after the workshop or operating place
③The presence of foam in the cleaning solution will also affect the visibility of the cleaned surface, which is not conducive to the degree of cleaning on the observing side
④ Excessive foam during the use of water-based cleaning agent affects cleaning
⑤ Foam will reduce the scrubbing strength of the washing machine because of the lubricating effect, which will affect the cleanliness.
3. Analysis of cleaning agent defoaming agent program
Daily-use transparent defoamer: Daily-use gel water, perfume (solubilizer), essence, aerosol laundry detergent, various daily chemicals, various cleaning agents, and can also be used for other transparent systems In industries and fields with long defoaming and anti-foaming time.
Features: The daily transparent defoamer developed by Nanhui Fine Chemicals is refined by a variety of special polyethers through a composite process. It has good defoaming and foam suppression and high shear resistance functions. It does not affect the appearance when added to the transparent system. , No oil floating, no demulsification, no floating, no residual wall hanging. No adverse effects on post-processing.
Defoamer for washing powder: Mainly used in granular washing powder, but also in other industries and fields that require a long time for foam suppression.
Features: Defoaming agent for washing powder is a defoaming agent specially developed by our scientific research institution for the special environment of washing powder. It is a spherical granular defoaming agent processed by specific equipment through specific structure of organic silicon and inorganic carrier. . Washing powder defoamer has a strong anti-foaming performance, and will not affect the washing effect due to foam in the washing stage, nor will it affect the washing effect of clothes due to organic silicon. The characteristic of this product is long anti-foaming time, and it can also be used in the rinsing stage. This product is a defoamer with excellent comprehensive performance with low dosage and low price.

A |
CQ-373 |
When the addition amount is 0.2%, the transparency is poor, there are a lot of small particulate suspended matter, defoaming is good, and foam suppression is good |
|
B |
CQ-374 |
When B CQ-374 is added at 0.2%, the transparency is slightly worse, there are a large amount of small particulate suspended matter, a small amount of floating matter, defoaming is good, and foam suppression is good. Better than A |
|
C |
CQ-373A |
When C CQ-373A is added at 0.2%, the transparency is a little worse, there are a lot of small particulate suspended matter, a small amount of floating matter, defoaming is good, and foam suppression is good. Better than A, worse than B |
|
D |
CQ-375 |
When the dosage of D CQ-375 is 0.2%, it has good transparency, no suspension, no tickets, defoaming and foam suppression. Better than B |
|
When the addition amount is 0.2%, several samples meet the needs of customers. The D number has the best effect and lower cost. It is recommended for customers. |
