解决方法要么是减少口模出口应力，要么是减少组分从熔体中分离的倾向。

Solutions are either to reduce die-exit stress or to reduce the tendency for components to separate from the melt.

有时，较低的口模温度会在口模内表面上生成一个冷却的树脂层，这个树脂层慢慢地移出到口模出口，然后与本体料流分离，从而引起积料。

Sometimes lower die temperatures can create a cool layer of resin on the inner surface of the die that creeps slowly to the die exit and then separates from the bulk flow, causing buildup.

并针对具体对象的要求进行了模化试验，其结果为该循环流化床锅炉高温旋风分离器设计，提供了依据。

The test results can provide a reliable basis for the design of high-temperature cyclone separators of circulating fluidized-bed boilers.
