Since the discovery of vulcanisation in the nineteenth century, rubber has been a major industrial product. From its inception, the use of vulcanising agents, reinforcing fillers and other additives has been a major feature of the rubber industry. Innumerable articles and texts attest to the chemist's skill in balancing the chemical and physical properties of the manufactured products.

作为一般操作的混合可以被视为同时发生的三个基本过程。简单的混合可确保混合物在整个整体中具有均匀的成分，至少与单个颗粒的大小相比，在大小上观看时。yabo214在固体混合的情况下（第11章），粒径不需要改变，但是整个混合物中颗粒的分布接近随机分布。yabo214如果剪切力足够大，则颗粒可能会像色散混合一样断裂，并且聚合物可能会像层流混合一样流动（第1yabo2141章）。在这两个过程中，由于混合过程，原始颗粒或流体元件的大小会发生变化。yabo214然后，混合物的性质取决于混合过程中达到的基本结构的大小。

In the case of laminar mixing, the size may be the striation thickness of a hypothetical fluid element, which is inversely related to the total shear strain. If relatively strong particles, or aggregates of particles, are present, these must be reduced in size by the action of forces generated by flow in the mixer. Then the size is the actual additive particle size.

The relative balance between the importance of these three processes in determining the efficiency of mixing and the product quality depends upon the attraction between additive particles, the rubber flow properties, the geometry of the mixer and the operating conditions such as temperature, mixing time and rotor speed.

操作条件，原材料特性和混合质量的相互作用可能是可分析的强大现象。但是，在许多情况下，可以做出许多关于操作的简化假设。
