En el proceso de granulaci\u00f3n de pl\u00e1sticos, es un problema relativamente com\u00fan encontrar manchas negras en los gr\u00e1nulos. \u00bfEs un problema de la m\u00e1quina granuladora de pl\u00e1stico<\/a>, de las materias primas u otros factores los que conducen a tal fen\u00f3meno? De hecho, el problema de las manchas negras en el proceso de granulaci\u00f3n es un fen\u00f3meno de fallo com\u00fan, especialmente m\u00e1s obvio en los gr\u00e1nulos de color claro.

puntos negros en bolitas de pl\u00e1stico<\/figcaption><\/figure> <\/div>

Estos puntos negros son el deterioro t\u00e9rmico pl\u00e1stico residual de la m\u00e1quina de pellets de pl\u00e1stico despu\u00e9s del carburo. Para garantizar la calidad de los pellets de pl\u00e1stico, el personal debe limpiar con frecuencia el carburo de la m\u00e1quina.<\/p>

Use harder plastic or its return material and white mineral oil for cleaning, and the temperature should be appropriately increased by 10~15\u00b0C. <\/p>

At this time, the plasticizing ability of the small extruder should be considered. For large and medium-sized extruders that can plasticize ultra-high molecular weight plastics, they can be cleaned with ultra-high molecular weight plastics or their return materials and white mineral oil. <\/p>

Because the hardness of ultra-high molecular weight plastics is better, and when the temperature is high, the cleaning object will be softened, so that it becomes easy to fall off, which is beneficial to the carbides being carried out by the plastic melt.<\/p>

During the cleaning process, the speed of the plastic pellet machine can be repeatedly switched between low speed and high speed. If there is still a spare motor load, you can repeatedly stop and restart the extruder several times during the operation, which can improve the cleaning effect. <\/p>

When the carbide in the plastic melt is obviously reduced, gradually adjust to the appropriate temperature, then the normal production.<\/p>","protected":false},"excerpt":{"rendered":"

In the process of plastic granulation, it is a relatively common problem to encounter black spots on the pellets. Is it the problem of plastic pellet machine, the problem of raw materials, or other factors that lead to such a phenomenon?
