1降低天然橡胶粘度为使天然橡胶(NR)具有较好的加工性能,通常需要适当降低其粘度。降低粘度的方法称之为塑炼,是通过混炼过程中聚合物断链而实现的。历史上,首先进行单独混炼,该阶段称之为预塑炼,是将NR或NR与称之为塑解剂的活性化学品一起加到炼胶机中混炼几分钟,随后再将预塑 1 Reduce the viscosity of natural rubber To make natural rubber (NR) has better processing properties, usually need to properly reduce its viscosity. The method of reducing the viscosity is called mastication and is accomplished by polymer chain scission during compounding. Historically, first, a separate kneading operation, known as pre-plasticizing, has been conducted by adding NR or NR together with an active chemical known as a peptizer to the blender for a few minutes, followed by pre-mixing Plastic
