In the existing market, there are the following waste plastic bags must not be able to buy, otherwise it will not be worth the candle.
The first type: woven bags containing toxic, oxidizing or corrosive chemicals. After the woven bags hold the chemicals for a long time, the chemicals enter the molecular gaps of the plastic and are difficult to remove.
There was once a company producing PP recycled materials bought 10 tons of raw material woven bags containing sulfur, raw materials are good, the price is reasonable. There should be a profit of more than one million yuan. The actual situation is a loss of one million yuan. Why? Buy it back, put it together with other white material bags, wait until it is cleaned, go to the granulator, the problem arises, an irritating odor makes people breathe uncomfortable, and continuous ventilation does not work. The particle foaming can only be discontinued. All raw materials are carefully cleaned again for the second time to extend the soaking time and finally re-granulated. The situation has improved, but the particles are still foaming, resulting in forty tons of all raw materials on the site. All particles are a bit foamy and have a bit of strange taste. Reduce the selling price. When the user goes back to use, the drawing is easy to break and the taste is unpleasant. It can only be blended with other materials, and even the surface finish of injection molded products can not reach! The result can be imagined!
In addition, a PE particle processing plant pulled the inner membrane of the raw material packaging bag of the chemical plant and pulled it back for several days. It found that all the grass around the raw material site was dead. It was cleaned without attention, and a small part of the sewage flowed to the next fish. Tang, thousands of fish all white belly up, the consequences are serious!
The third category: woven bags containing dyes and other raw materials, the reasons for which are similar to the above.
There is a processing plant by the river, into more than 10,000 printing and dyeing plant raw material bags, this thought that little impact, did not expect very powerful paint, four hours cleaning, let the river slowly change the color of 100 meters, the report of the good The phone also let the environmental protection test arrived on the scene!
Therefore, there are irritating tastes, waste plastics packaging toxic and hazardous chemical raw materials, must be clear, can produce, otherwise, waste plastic is very much. This waste plastic give you can not!
