The production process of papermaking defoamers involves multiple steps, including formula determination, raw material procurement, mixing and stirring, heating and dissolution, pH adjustment, filtration and purification, and packaging.

Firstly, determining the formula and composition of the defoamer is a crucial step. The formula should include surfactants, diluents, stabilizers, and other raw materials to ensure the defoaming performance and stability of the product.

Secondly, purchase the required raw materials according to the formula ratio, weigh and prepare them. Pour the required surfactants and diluents into appropriate containers, and use stirring equipment to thoroughly mix the ingredients to ensure uniform dispersion.

Next, heat the mixed raw materials to an appropriate temperature to promote reaction and dissolution. While heating, continue to use the stirring equipment to evenly stir the raw materials, ensuring that the reaction proceeds uniformly.

Then, according to the formula requirements, acid or alkali is used to adjust the pH value of the raw material solution to achieve the most suitable reaction conditions. This step is crucial for the stability and performance of the product.

Afterwards, the reacted solution is filtered through equipment such as a filter or filter paper to remove impurities and solid particles, resulting in a clear liquid. This step ensures the purity and quality of the product.

Finally, package the purified defoamer liquid in suitable containers such as plastic bottles and buckets. During storage, be careful to avoid direct sunlight and high temperature environments to ensure product quality and stability.

In terms of quality control, regular performance testing should be conducted on products, including testing of defoaming performance, foam suppression performance, stability and other indicators. At the same time, continuous optimization and improvement of production processes are carried out to enhance product quality and production efficiency.
