Regarding the question of whether talcum powder is used in the vulcanization process of rubber airbags, it is necessary first to clarify that vulcanization is an important link in the rubber processing process, which involves transforming the rubber molecular chain from a linear structure to a mesh structure, thereby improving the physical properties and chemical stability of the rubber. However, whether talcum powder is used in the vulcanization process depends mainly on the specific production process and the requirements of the rubber product.
In general, talcum powder may be used as a filler, release agent or release agent in rubber processing, but it is not necessary in the vulcanization process. The vulcanization process mainly relies on vulcanizing agents (such as sulfur, peroxide, etc.) and vulcanization conditions (such as temperature, time, pressure, etc.) to achieve the cross-linking reaction of rubber.
For the vulcanization of rubber airbags, if the production process does not specifically specify the need to use talcum powder, then the vulcanization process may not include the use of talcum powder. However, it should be noted that after vulcanization or long-term storage of rubber airbags, to maintain its shape and prevent adhesion and aging, some post-treatment measures may be taken, including applying talcum powder and other release agents on the airbag’s surface.
Specifically, when the rubber airbag is not used for a long time, to keep it dry, and prevent adhesion and aging, it is usually washed and dried, and talcum powder and other isolation agents are applied on the inner and outer surfaces, and then placed in a dry, cool and ventilated place indoors. In addition, to prevent the rubber airbag from being punctured by sharp hard objects or other physical damage, it is also necessary to avoid contact with fire sources, oils, and organic solvents, and avoid piling heavy objects on the airbag.
In summary, whether talcum powder is used in the vulcanization process of the rubber airbag depends on the specific production process and product requirements. After vulcanization or during long-term storage, to maintain the performance and shape of the airbag, measures such as talcum powder and other isolation agents may be taken. But please note that the above information is for reference only, and the rubber airbag manufacturer or experts in related fields should be consulted for details.
