Katika mchakato wa kuchakata plastiki, ni jambo la kawaida kukutana na madoa meusi kwenye vipande. Je, ni tatizo la mashine ya kutengeneza vipande vya plastiki, tatizo la malighafi, au mambo mengine yanayosababisha jambo kama hilo? Kwa kweli, shida ya madoa meusi katika mchakato wa kuchakata ni jambo la kawaida la kushindwa, haswa katika vipande vya rangi nyepesi huonekana zaidi. Kwa hivyo tunawezaje kuboresha shida hii?

Madoa haya meusi ni mabaki ya plastiki mafuta kuzorota kwa mashine ya plastiki pellet baada ya CARBIDE, ili kuhakikisha ubora wa pellets plastiki, wafanyakazi lazima mara nyingi kusafisha CARBIDE mashine.

Use harder plastic or its return material and white mineral oil for cleaning, and the temperature should be appropriately increased by 10~15°C.

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.

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.

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.

When the carbide in the plastic melt is obviously reduced, gradually adjust to the appropriate temperature, then the normal production.
