Solutions for industrial cleaning defoamers

Customer question

In the industrial cleaning process, especially the chemical cleaning process, it is easier to encounter foam problems. Two methods of industrial cleaning, chemical cleaning and physical cleaning, are commonly used. Chemical cleaning mainly uses chemical agents to clean up surface contaminants to achieve chemical conversion, dissolution, and achieve the effects of rust removal, degreasing and decontamination. Chemical cleaning is widely used , The application is more common and accounts for about 60% of industrial cleaning; physical cleaning generally uses high pressure or jet cleaning, accounting for about 40%.

Chemical cleaning is relatively clean and can achieve higher cleaning accuracy. However, in the process of chemical cleaning, various chemicals are likely to cause foam problems, which will affect the cleaning progress and effect. How to solve the problem of chemical cleaning foam, Nanhui defoamer manufacturer will reveal the answer for you through customer cases.

1. Customer information: A Thai manufacturer once encountered the problem of chemical cleaning foam, contacted Nanhui through the Internet, the defoamer chemical engineer of Nanhui manufacturer, based on the cause of foaming, through sample experiments, provided it with a targeted A chemical cleaning and defoaming solution.

2. Sample information: chemical cleaning agent

Customer request

1. High cleaning precision is required. It is hoped that the addition of defoamer will not affect the cleaning accuracy and the cleaning process.

2. Due to the large amount of use, it is hoped that the amount of defoamer will be less and the cost of addition can be controlled.

3. The defoamer has good stability, and the cleaning chemicals are often mixed cleaning chemicals with strong acid or strong alkali. The added industrial cleaning defoamer should be able to continue defoaming under acid-base environment.

Solution

1. Analysis of the cause of foaming in chemical cleaning

(1) The chemical agent contains a large amount of surface active ingredients, causing foaming.

(2) The process of heating or mechanical vibration causes foam to be produced.

2. The hazards of bubbles

(1) It is not conducive to observe the cleanliness of cleaning and increase cleaning costs.

(2) Foam will waste more industrial water and directly discharge foam sewage, which will pollute the surrounding environment.

(3) Produce cleaning residue, which affects subsequent processes.

3. Chemical cleaning and defoaming program

Facing the problem of chemical foaming, many companies have not found the correct way to deal with it. Since it is a chemical agent that foams, if you want to eliminate chemical foam, you can solve the foam problem through chemical defoaming methods. It is common to add defoamers. In the case of chemical cleaning foam problems, industrial cleaning defoamers can be added to defoam.

The industrial cleaning defoamer developed by Nanhui defoaming agent manufacturer for industrial cleaning agent and metal surface treatment has the advantages of continuous defoaming under high temperature, strong acid and strong alkali environment. The defoaming time is fast and the foam suppression time is long. Easily eliminate the foam produced by various surfactants and chemical agents.

4. For chemical cleaning foam experiment

Through the chemical agent samples sent by the customer, the chemical engineer of Nanhui defoamer passed the defoaming plan of the Thai customer and above through experimental analysis. After the sample, the customer chose plan three. The defoamer of plan three is compounded through a special process, which has stronger defoaming performance and relatively stable defoaming performance.

Nanhui is a manufacturer with years of application experience. It has far more defoaming technology than other antifoaming agents in the market. From the above cases, we prove the strength of our Nanhui defoamer. We have a group of excellent defoaming engineers, and an independent laboratory that facilitates defoaming experiments with foams that are difficult for customers to solve. If you want to know more about defoamer products, you can call our hotline: +86 13428601010.
