The Mixing of Rubber (eBook, PDF)

Produktbeschreibung

Despite mature applications, advanced technology, and high volume, rubber compounding has never had a book of its own. Today, emerging applications such as tire reclamation and smoke-resistant cables combine with an industry push into engineering materials to create new kinds of compounds with new quality control problems. The Mixing of Rubber has been developed over several years in conjunction with the Farrel Corp./Connecticut Rubber Group course to educate the hands-on compounder and the end user as well. It covers machinery, mixing, process control, quality control, plant operations and mixing advice for specific compounds. Like the course, the book assumes no prior knowledge of rubber compounding but leads the technologist through the process from mix procedure to test.
