如果发生口模积料，尝试使用别的供应商的类似牌号。
If die buildup occurs, try a similar grade from another supplier.
空气清扫还有冷却积料的好处，以便积料不会氧化和变黑。
Air sweeps also have the benefit that they can cool die buildup so it doesn't oxidize and turn dark.
你可能想测试口模积料的化学成分以确定里面究竟有什么。
You may want to test the die buildup chemically to see what's in it.
本机具有筒体无死角，不积料，速度快，混合时间短的特点。
This Mixer has the following distinguishing features. No blind Angle in the cylinders, no accumulation of materials. High speed, and short mixing mixing time.
例如，高度不相容的聚合物熔融掺混时，常常出现极度的口模积料。
For example, extreme die buildup often occurs when highly incompatible polymers are melt blended.
不同的材料产生不同种类的积料，从稀的流水状的积料到粘稠的绒毛状的积料。
Different materials produce different sorts of die buildup, from thin and runny to thick and fluffy.
本发明通过将落料集中于受刀面及将物料导流，以达到减少漏料与积料的机率。
The shredding machine gathers fallen materials on the cutting surface and guides the materials to achieve the aim of reducing the probability of material leakage and material accumulation.
某些供应商的树脂会比别的供应商产生更多的积料，即使这种树脂具有同样的规格。
Resins from some suppliers will generate more die buildup than others, even when the resins have exactly the same specifications.
具有窄分子量分布的树脂往往难于加工，它还产生低分子组分，这反过来又引起积料。
Resins with narrow MWD are often hard to process, which can generate low-MW components, which in turn can cause die buildup.
具有窄分子量分布的树脂会有低的出口膨胀，但这不意味着它一定有较少的口模积料。
Resins with narrow molecular-weight distribution can have lower die swell, but this doesn't necessarily mean less buildup.
改变挤出物的牵引角度，就可以改变挤出物在口模上的堆积位置，这样就容易清除积料了。
Changing the Angle at which the extrudate is drawn away from the die can change the placement of buildup on the die and make it easier to clean.
清除积料后在口模出料口使用脱模剂或者硅酮可以减轻积料程度并延长两次清除之间的时间。
Applying mold release or silicone to the die exit area after cleaning can reduce the rate of buildup and extend the time between cleanings.
无论交叉流浓相换热器，还是传统NSP窑，必须注重低限风速的意义，防止或减少积料、塌料现象的发生；
For both crossed-flow in dense phase heat exchanger and NSP kiln, low limitation for gas speed must be noticed to prevent from or to reduce materials accumulation or collapse.
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.
修改的口模出口据称可以减少口模积料，包括一种方形陡出口、尖形陡出口、弧形过渡形出口、外扩台阶出口、内扩台阶出口、外展形出口(见图)。
Modified die exits that claim to decrease die buildup include a sharp square exit, sharp pointed exit, radiused exit, outward-stepped exit, inward-stepped exit, and outward-flared exit (see diagram).
