LSP Pet Plastic Recycling Machine Line With Liquid State Polymerization System For IV Improvement

The innovative structural design of the reactor, increases the reaction area of polymerization, improves the fluidity of PET melt, makes the reaction time shorter.

With our new smart control system, operations and real-time monitoring is more convenient than ever before, to predict maintenance and improve production efficiency.

Frequency conversion equipment is used to automatically adjust operation frequency. The multiple level temperature control system minimizes the required heating energy consumption and reduces the operation cost of the whole system.

With our good homogenization feature, the reactor could mix different raw materials into homogeneous melt.

Through the buffer of our reactor, the whole production system is more controllable, increase output and avoid time lost during the process of replacing filters.

LSP is an extremely efficient alternative to a Solid State Polymerization (SSP) as there is no energy needed to cool the polymer down and then reheat it. Further, the reaction time in the melt phase is considerably faster than in the solid phase, which also contributes to the better economics of the LSPLINE™ system.

Because the source of recycled material is complex, the components are difficult to guarantee, which shows that the fluctuations of melt in production process. In order to stabilize the IV, the reactor runs at a certain speed, so that the internal melt is fully mixed.

Because PET re-polymerization is carried out in a high vacuum state, the low molecular material contained in the raw material and the auxiliaries will be vaporized in high temperature.

There are still a large number of hydroxyl and carboxyl molecules in the raw materials, and the catalytic system is still effective. the polymerization still occur under certain temperature and vacuum state, The molecular chain and IV will increase.

The first melt filter after the extrusion can filter the inorganic impurities, and facilitate the further reaction.

Under high vacuum conditions, the oligomers and decomposed gases are separated from the melt and removed into the vacuum system.

High-viscosity melt passes through the last melt filter and the inorganic impurities that still remain in the melt will be filtered.

After multiple filtration and homogenization, the recycled polyester melt has higher purity and IV, and color of the end product are more uniform.

Under the high temperature and vacuum polymerization reaction, the molecular chains and IV are continuously increased, and the strength of the produced polyester product is also better.

The unique shaftless design makes the melt filming reaction smoother, avoiding the risk of material accumulation.

The larger reaction area has better decontamination efficiency, better IV-increase effect, and achieve higher purity after reaction.

Innovative mesh design allows smoother melt flow, which makes the liquid level control more stable and can be controlled at a very low level, allowing the melt reaction time to be shortened and the end product color to be better.
