The mechanism of action of DC-193: Revealing the secret of foam stability

To understand how DC-193 plays a role in household appliances, we first need to understand its specific mechanism of action in the formation of polyurethane foam. As a nonionic surfactant, DC-193's core function is to regulate and stabilize the bubble interface in the foam system, which directly affects the quality and performance of the final foam.

The basic process of foam formation

The formation of polyurethane foam is a complex chemical reaction process involving the polymerization of polyols and isocyanates. In this process, the generation and stability of bubbles are key steps. The main function of DC-193 in this stage is to reduce the surface tension of the liquid, promote the formation of bubbles, and prevent the merger or burst of bubbles, thereby ensuring the uniformity and stability of the foam structure.

Reduce surface tension

DC-193 molecules contain hydrophilic and hydrophobic groups, which enables them to form a protective film between water and oil phases, effectively reducing the surface tension between the two phases. This characteristic is crucial to prevent rapid rupture caused by excessive surface tension in the early stages of bubble formation. By reducing surface tension, DC-193 helpsA more stable and lasting bubble structure is formed.

Control bubble size and distribution

In addition to reducing surface tension, DC-193 can further control the size and distribution of bubbles by regulating the viscosity and fluidity in the foam system. Appropriate bubble size and uniform distribution are crucial to improve the mechanical properties and thermal insulation of the foam. Through its unique molecular structure and chemical properties, DC-193 can effectively disperse bubbles and avoid excessively large or too small bubbles, thereby ensuring the overall quality and performance of the foam.

Experimental data support

To verify the above theory, the researchers conducted several experiments. For example, in a comparative experiment, polyurethane foam using DC-193 showed higher compression strength and lower thermal conductivity, which directly demonstrated the effectiveness of DC-193 in improving energy efficiency and extending service life in household appliances. .

To sum up, DC-193 has significantly improved the stability and performance of polyurethane foam through its various functions, including reducing surface tension, controlling bubble size and distribution, thus playing a role in the application of household appliances The role of substitution.

The multi-functional role of DC-193: The hero behind the scenes to improve the performance of home appliances

DC-193 is used in the field of home appliances much more than simple foam stability. Its versatility is reflected in many aspects of household appliances. From improving mechanical strength to enhancing thermal insulation effects, to optimizing fluidity and mold release, DC-193 has demonstrated its unique advantages.

Improve mechanical strength

DC-193 significantly enhances the mechanical strength of polyurethane foam by optimizing the foam structure. This means that foam treated with DC-193 can better resist external pressure and impact, which is particularly important for household appliances such as refrigerators and freezers that need to withstand heavy pressure. Experimental data show that the foam with DC-193 added increases the mechanical strength by about 20% compared to similar products that have not been added, greatly improving the durability and reliability of the product.

Enhanced thermal insulation effect

In household appliances, especially refrigeration equipment, thermal insulation effect is one of the important indicators for measuring product performance. DC-193 greatly reduces heat transfer by forming a more uniform and dense foam structure, thereby improving the thermal insulation effect. According to laboratory tests, using DC-193's polyurethane foam can reduce heat conductivity to 0.022 W/(m·K), which is nearly 30% lower than ordinary foam. Such improvements not only improve the energy-saving effect of the equipment, but also extend its service life.

Optimize fluidity and mold release

In the production process, the flowability and mold release properties of the foam directly affect the quality and production efficiency of the finished product. DC-193 improves the fluidity of the foam by adjusting the viscosity of the foam system, so that the foam can fill the mold more evenly., reduce gaps and defects. In addition, DC-193 can also enhance the separation effect between the foam and the mold, which is the so-called mold release property, which not only speeds up the production cycle, but also reduces the scrap rate. According to industry reports, after the adoption of DC-193, production efficiency has increased by about 15%, while the scrap rate has decreased by more than 10%.

Comprehensive performance improvement

In general, the application of DC-193 in household appliances not only improves the mechanical properties and thermal insulation effect of the product, but also optimizes the production process and reduces costs. These advantages have combined effect to significantly improve the competitiveness of household appliances in the market. Whether from the perspective of consumers or manufacturers, DC-193 is an indispensable helper.
