The use of solvent recovery machines for plastic dissolution and separation has significant advantages, mainly reflected in the following aspects:
1. Significantly reduce solvent costs
·Direct recycling: The solvent recycling machine can separate and purify the solvent in the mixed solution after dissolving plastics through distillation, condensation and other technologies, with a recovery rate of 80% to 95%, greatly reducing the purchase of new solvents.
·Long term economy: Although equipment requires initial investment, long-term operation can save a lot of solvent costs, especially suitable for large-scale or continuous production scenarios.
2. Reduce environmental impact and compliance risks
·Avoid hazardous waste discharge: Waste solvents are often classified as hazardous waste, with high disposal costs and environmental pollution. The recycling machine minimizes waste liquid emissions through closed-loop processing.
·Compliant with environmental regulations: Countries are increasingly strict with organic solvent emissions and waste management, and recycling machines help companies meet environmental requirements and reduce the risk of fines or production shutdowns.
·Support circular economy: reduce chemical consumption and waste generation, and enhance the sustainability of processes.
3. Improve sorting efficiency and process stability
·Controllable solvent purity: The recovered solvent has a high purity (usually>90%) and can be reused for dissolution and sorting to avoid impurities accumulating and affecting the sorting effect (such as a decrease in plastic purity).
·Continuous production: Combined with a recycling system, solvent recycling can be achieved, reducing production interruptions and improving overall sorting efficiency.
·Optimize resource utilization: Accurately control the ratio of solvents to plastics to improve the recovery rate and purity of target plastics (such as PS, ABS, etc.).
4. Improve homework safety and health conditions
·Reduce volatilization exposure: A closed recycling system can reduce the volatilization of solvents in the workshop, reduce the risk of fire, explosion, and employee health hazards (such as respiratory irritation and neurological damage).
·Automated operation: Reduce the chance of manual contact with chemicals and improve production safety.
5. Adapt to diverse combinations of solvents and plastics
·Flexible handling of different systems: For the combination of commonly used solvents (such as xylene, acetone, THF, etc.) and plastics (PS, PE, PVC, etc.), the recycling machine can achieve efficient separation by adjusting parameters (temperature, pressure).
The solvent recovery machine is not only a cost control tool for plastic dissolution and separation, but also a key link in promoting the environmental protection, industrialization, and economic feasibility of this technology. It significantly reduces chemical consumption and waste emissions through closed-loop circulation, while improving sorting efficiency and safety, and is an important component of high-value plastic recycling processes. When introducing enterprises, comprehensive planning should be carried out based on their own scale, solvent type, and environmental requirements.
