Cyclopentane foaming agent foaming principle
Chemicals have a wide range of applications in production, among which cyclopentane blowing agent is a common chemical, which is widely used in the production of various foaming materials. So, what is the foaming principle of cyclopentane foaming agent?
Cyclopentane blowing agent can be divided into two categories, one is physical blowing agent, this blowing agent is through the physical reaction to produce gas, thus foaming process; The other is a chemical blowing agent, which is a process of foaming through a chemical reaction to produce gas.
For physical blowing agents, the principle is mainly to use the stability of the gas and the change of pressure to achieve the purpose of foaming. In this foaming agent, cyclopentane and other substances are added to the foam material. When the foam material is heated, the gas inside the cyclopentane and other substances will expand due to heat, which increases the pressure and eventually leads to foaming.
It is worth noting that the foaming process of physical foaming agents is closely related to external factors such as ambient temperature. When the ambient temperature increases, the pressure of the internal gas will also increase correspondingly, which will aggravate the foaming process, which is why the foaming speed of the foaming material will be faster in the summer than in the winter.
For chemical blowing agents, the principle is different from physical blowing agents. Chemical blowing agents produce gas through chemical reactions, so as to achieve the purpose of foaming. In this foaming agent, cyclopentane contains alkaline substances, and when it comes into contact with acid substances, it will undergo a neutral reaction, and this reaction will produce a large amount of carbon dioxide and other gases, resulting in the foaming process.
SHANDONG SENZHIHAI NEW MATERIAL CO., LTD recently exported a batch of bottled cyclopentane to Pakistan. This is the packing site of our factory on December 9.
In general, the foaming principle of cyclopentane blowing agents is very simple and clear. However, in the actual application, we need to combine the nature of the specific material and the characteristics of the use of the environment to make a reasonable choice and use. Only in this way can we achieve the best results in manufacturing
