The game s popularity dwindled almost to zero during the 1700s, but in 1850, charles goodyear invented a vulcanization process for rubber, and during the 1850s, players began to experiment with using the bouncier rubber balls outdoors on grass 這種運(yùn)動(dòng)在1700年,曾經(jīng)銷(xiāo)聲匿跡,但是在1850年發(fā)明了一種硫化制造橡膠的工藝,在那時(shí),球員們開(kāi)始嘗試在草坪上玩這種新式球。
The development history of preparation technology of reactive extrusion dynamic vulcanization for thermoplastic dynamic vulcanizates was introduced, and reactive extrusion dynamic vulcanization technology, including its characteristics, preparation technology conditions, vulcanization rate and vulcanization process, was systematically discussed 摘要介紹了制備熱塑性動(dòng)態(tài)硫化膠的反應(yīng)擠出動(dòng)態(tài)硫化技術(shù)的發(fā)展歷史,系統(tǒng)論述了該技術(shù)的特點(diǎn)、工藝條件、硫化速率及硫化過(guò)程。
