Have you ever heard of a road paved with plastic bottles? A South African company crushes plastic bottles, heats them up, and then adds additives to pave the roads. The company used about 40,000 recycled plastic bottles to pave more than 400 meters of road, making it the first of its kind in Africa.
At the end of 2016, the jerseys worn by the starting athletes of the two club teams sponsored by Adidas, Bayern Munich, and Real Madrid, during their matches were also made using 308 pieces of recycled plastic bottles.
In the above cases, we see more possibilities for plastic bottle recycling and a promising future for plastic bottle recycling. The common way to recycle plastic bottles is to take them off the label, crush them and wash them to get clean bottle pieces. So how to get high-quality bottle flakes and get higher profits? After reading the following analysis, you will have the answer.
PVC content of plastic bottle flakes
As we all know, PVC in used recycled PET bottles is mainly in the form of labels. Since PVC is different from PET, it has to be removed before crushing and processing to ensure the quality of the recycled bottle flakes.
Some slightly larger plastic bottle recycling manufacturers use de-labeling machines to remove the labels. The de-labeling machine made by Shuliy Group can reach 98% or even above, which can effectively remove the label. Some manufacturers with more stringent requirements will be equipped with a manual sorting table after the PET label remover machine. On the one hand, check whether the machine is de-label clean, if there is residual label paper that can be removed manually, and the other side can also be used for conveying materials.
Impurities of plastic bottle flakes
Recycled plastic bottles may contain various impurities, such as sand, dirt, wood pieces, oil, and so on. Therefore, in order to get clean bottle chips, we need to go through many cleaning processes, such as PET bottle flakes hot washing machine, frictional washing machine, pet bottle washing machine, and so on.
In addition, in the hot washing process of the hot washing pot, an appropriate amount of industrial alkali can be added to remove the residual oil and other adhesive impurities on the bottle chips.
Water content of plastic bottle flakes
Generally speaking, the lower the water content of plastic bottle chips, the better. Because water vapor in the material will cause bubbles inside the product, affecting the strength of the finished product. The most important thing is that high moisture content will cause the material to decompose when it is melted.
So if you plan to engage in or are engaged in plastic recycling, be sure to have a plastic dryer machine in the PET bottle recycling line. It is used to dry the cleaned bottle slices and reduce the moisture in them.
Summary
After the above steps, you can get high-quality PET bottle flakes. If you need one of the machines mentioned above, please feel free to contact us. Shurliy Group can provide you with the most suitable machine for your business.
