[China Aluminum Network] At present, there are many aluminum-plastic composites on the market, so aluminum-plastic separation has become a hot spot for investment. However, many investors have found that profits are limited or unprofitable, and even lose money. Discussion.
1. Aluminium-plastic panel: The process of separating aluminum-plastic panel is relatively simple and the processing cost is not high. However, due to the poor quality of plastic, the market price does not exceed 3,000 yuan/ton, while the raw material price is relatively high (about 4,000 yuan/ton. ), so the profit is low.
2. Pellets: The domestic scrap price is relatively high (4000-4500 yuan/ton). Due to the low aluminum content (about 10%), although the processing cost is lower, the profit is not high. There is also the pvc in the separation process. In the process, it is contaminated with printing inks and stained (mainly the formulation problem), which affects the selling price.
At present, there are many scrap plates in imported wastes, and the price is not high, but they cannot be separated by ordinary methods. Moreover, PE film is sandwiched between aluminum and pvc, which requires further separation of PVC and PE, which causes increased costs.
three. Aluminum-plastic compound film: Many operators find that the purchased technology is not problematic. However, the mass production of the solvent during mass production is very costly. In fact, this problem is mainly due to equipment problems. In general, the use of low-boiling-point solvent requires better sealing performance of the equipment. At the same time, it must have a better condensing system to ensure the recovery of the solvent (at least 85% recovery). Only in this way can the cost be reduced. According to our experience, solvent recovery can reach 90%. Moreover, many aluminum plastic films can be separated with lower cost formulations, such as Tetra Pak packaging, there is no need to use solvents. Using different formulations for different materials is another way to reduce costs.
In short, we must try our best to formulate and implement equipment, reduce costs, and increase profits.
