Mbinu za kurejeleza karatasi za filamu za plastiki tofauti

Mbinu za kuchakata karatasi za filamu za plastiki za vifaa tofauti ni tofauti kidogo, lakini nyingi zinahitaji hatua zifuatazo.

First of all, the raw material needs to be crushed and washed easily by a crashing and cleaning machine, it is the first step in the plastic film recycling line, then they will be washed thoroughly in a sink.

After that, the wet plastic film sheet will be dehydrated and will be melted as a mushy shape with electromagnetic heating, long strips will be created by the plastic granulator machine, then those long strips will be cooled in a cold water sink, at this moment, they will be cut by the pellet cutting machine, at last, the pellets will be stored in the storage bin.

Due to the characteristics of PVC material, it is best not to wash it in the process of recycling PVC plastic film. If a water washing step is necessary, the raw materials must be dried. And in the processing process, chemical ingredients need to be added.

Generally, the quality of plastic particles is related to the water content of raw materials. Too much water content will seriously affect the quality of plastic particles.

Linje ya uzalishaji wa kuchakata filamu ya plastiki ya PE

Kuna aina maalum ya filamu ya plastiki ya PE, yaani filamu ya kushikilia. Katika maduka makubwa, ufungaji wa chakula kilichogandishwa au mboga mboga mpya mara nyingi umefunikwa na filamu ya plastiki. Hata hivyo, aina hii ya filamu ya kushikilia mara nyingi imewekwa lebo. Wakati huu, separator ya karatasi-plastiki inahitajika kutenganisha karatasi ya lebo na filamu ya kushikilia.
