LSP
ACERETECH
LSP (Liquid Polycondensation) improves the quality of recycled PET materials (fibers, flakes, films, low IV polymers), produces high-grade PET fibers, PET packaging tape, PET pellets, PET films, recycled bottle-to-bottle and fiber-to-fiber, and improves the recycling rate and quality of resources.
Innovative structure
The innovative reactor structure design increases the polymerization reaction area and improves the flowability of the PET melt, resulting in shorter reaction times.
Intelligent control
With our new intelligent control system, operation and real-time monitoring is easier than ever, allowing for predictive maintenance and increased production efficiency.
High energy efficiency
Frequency conversion equipment is used to automatically adjust the operating frequency. The multi-stage temperature control system minimizes the required heating energy consumption and reduces the operating costs of the entire system.
LSP excellent IV improvement effect
With our good homogenization characteristics, the reactor can mix different raw materials into a homogeneous melt.
LSP enables higher throughput
Through the buffer of our reactor, the whole production system is more controllable, and the output is increased to avoid wasting time in the process of filter replacement.
Working principle of LSP
LSP is an extremely effective alternative to solid state polymerization (SSP) because it does not require energy to cool the polymer and then heat it. In addition, the reaction time of the melt phase is much faster than that of the solid phase, which also helps to improve LSPLINE ™ Economy of the system.
Homogenization
Due to the complex source of recycled materials, it is difficult to ensure the composition, which shows the fluctuation of the melt in the production process. In order to stabilize IV, the reactor runs at a certain speed to fully mix the internal melt.
Remove impurities
Since PET is re polymerized under high vacuum, low molecular substances contained in raw materials and additives will be vaporized under high temperature.
Molecular chain growth
There are still a large number of hydroxyl and carboxyl molecules in the raw materials, and the catalytic system is still effective. Polymerization will still occur under certain temperature and vacuum conditions, and the molecular chain and IV will increase.
After extrusion
The first melt filter after extrusion filters out inorganic impurities and facilitates further reactions.
During the reaction
Under high vacuum conditions, oligomers and decomposition gases are separated from the melt and discharged into the vacuum system.
After the reaction
The high viscosity melt passes through the last melt filter and the inorganic impurities still remaining in the melt are filtered out.
High purity
The recycled polyester melt is filtered and homogenized several times, resulting in higher purity and IV and more uniform color of the finished product.
High Strength
Under the high temperature vacuum polymerization reaction, the molecular chain and IV keep increasing, and the strength of the produced polyester products is also better.
Non-shaft design
Unique non-axis design for smoother melt film reaction and avoiding the risk of material build-up.
Larger reaction area
Larger reaction area has better decontamination efficiency, better IV increase effect, and higher purity obtained after reaction.
Shorter reaction time
The innovative mesh design allows for smoother melt flow and more stable level control at very low levels, allowing for shorter melt reaction time and better color of the finished product.
