Nanhui factory industrial cleaning defoamer customer case

Customer question

In many industrial production processes, cleaning is required, and some products need to be cleaned in the final link. Such as metal and glass electroplating, plastic parts, spray paint, etc. However, in the process of industrial cleaning, the product needs to be cleaned to achieve a certain cleaning accuracy before it can be qualified. This also causes the problem of cleaning foam. Cleaning foam not only wastes more water resources, but may also be a cleaning effect. Not up to the requirements. Nanhui once provided targeted defoaming solutions for a company in Singapore.

1. Customer information: A Singaporean manufacturer of plastic parts encountered cleaning foam problems, mainly because too much foam in the cleaning agent, which led to unclean cleaning and cleaning residue problems.

2. Sample information: industrial cleaning agent

Customer request

1. Stable defoaming, will not affect the cleaning process, and will not produce cleaning residues.

2. It can tolerate acid and alkali environment, and can continue to defoam and suppress foam in acid and alkali environment.

3. The defoaming agent has better defoaming and anti-foaming properties, the dosage can be controlled, and the dosage is small.

Solution

1. Analysis of the cause of foaming in plastic parts cleaning

(1) During the cleaning process, water flow and mechanical vibration cause blistering.

(2) The cleaning agent used contains a lot of surfactants, which causes a lot of foam.

(3) In the cleaning process, the cleaning agent and alkaline water solution are used for cleaning, which causes the surfactant to be adsorbed on the bubble film, forming a stable foam, and generating cleaning residue.

2. The hazards of cleaning foam for plastic parts

(1) Affect production efficiency. In order to prevent foam from overflowing, more space is needed to accommodate it. Therefore, in the dissolution process, the amount of material can only be reduced to the cooking pot and other equipment, which leads to a decrease in production capacity and production volume.

(2) It leads to an increase in production costs. Due to the retention of foam in the solution, the reaction cycle is prolonged, power consumption increases, and the output rate of a single tank will decrease, which ultimately leads to an increase in production costs.

(3) Affect the quality and use of the product. The foam in the solution will eventually be brought into the product as the processing progresses, thereby affecting the use and quality of the product.

3. Plastic parts cleaning and defoaming plan

For cleaning foaming problems, industrial cleaning defoamers can generally be used to solve the foaming problem. The industrial cleaning defoaming agent developed by Nanhui defoaming agent manufacturer for industrial cleaning is a defoaming agent made by processing organic and inorganic carriers with specific structures through specific equipment. The defoaming agent can not only eliminate in the cleaning and washing stage Foam does not affect the later process. It has the characteristics of resistance to high temperature, acid and alkali environment.
