Product action

Catalyst inner thermal insulation cotton has excellent thermal insulation performance. In the process of chemical reaction, it is often accompanied by the generation or absorption of heat. Thermal insulation cotton can effectively reduce the transfer of heat, make the ambient temperature of the catalyst more stable, and avoid the adverse effect of temperature fluctuations on the catalytic reaction. This helps to maintain the activity and selectivity of the catalyst, improve the efficiency of the reaction and the quality of the product.

Secondly, it can reduce energy consumption. By reducing heat loss, thermal insulation enables the reaction system to make better use of energy, thereby reducing energy requirements throughout the process. In the pursuit of energy conservation, emission reduction and sustainable development today, this advantage is particularly important.

In addition, the thermal insulation cotton can also protect the catalyst itself. High temperature may lead to structural changes of the catalyst, loss of active components or sintering problems, thus shortening its service life. The existence of thermal insulation cotton can reduce the impact of these adverse factors, extend the service life of the catalyst, and reduce production costs.

In addition, it helps to optimize reaction conditions. The ability to better control the reaction temperature allows researchers and engineers to more precisely adjust the reaction parameters and explore more optimized reaction conditions to achieve higher yields and selectivity.

Difference between expanded cotton and non-expanded cotton

Expansion cotton, as the name suggests, has the property of expanding under certain conditions. This expansiveness gives it a unique advantage. First, the expanded cotton can significantly increase its volume when heated or encountered with specific media, thus better filling the void inside the catalyst, providing a more uniform, tighter insulation and protection effect. This helps to maintain a stable temperature distribution within the catalyst, reducing local overheating or undercooling, thus ensuring the efficient catalytic reaction.

Second, the expansion characteristics of the expanded cotton enable it to adapt to the internal space of the catalyst of different shapes and sizes, with greater adaptability and flexibility.

However, non-expansive cotton also has its own characteristics. Non-expanded cotton usually has a more stable physical structure, is not prone to morphological changes during use, and can provide relatively stable thermal insulation and support performance.

Compared with expanded cotton, non-expanded cotton may be relatively weak in terms of thermal insulation properties, but in some catalytic reactions that require less stringent temperature changes, its stable performance can still meet the needs.
