Production Of Pure Water Mixed With Plastic Bucket “back Feed”
Manufacture of PET bottles to use more traditional antimony and germanium catalysts, such catalysts in the molding process of PET bottles will produce acetaldehyde, and in the high temperature of the PET bottle filling process, the heavy metal antimony easily separated from the PET into the liquid and thus harm the human body. Teijin introduced by the fiber-specific PURITY is a fourth generation (G4) new phosphorus-containing titanium catalyst, completely free of heavy metals, the use of the surface of the catalyst can Spinneret cleaner, improve transparency of polyester products.
It is understood that the new barrels of strength does not meet the requirements, in addition to the use of problems, there are many of them are mixed with the “back feed” reasons.
“Back feed” is a Barrel industry recycled waste materials, processed, and then commonly known as a production material. Reporter specifically ask a number of plastic products industry experts. According to reports, the State provides the material for the manufacture of polycarbonate water barrel, abbreviated “PC”. As the PC uses a wide range by adding different additives, but also can produce CD-ROM, car shade, elevated road noise barriers and the like. The production of these products by adding additives, many of them harmful.
A condition of anonymity told reporters the industry, a considerable number of enterprises in the manufacturing process have been blended with “back feed.” Bottled drinking water, city authorities had conducted a surprise inspection and found two barrels of the factories producing drinking water, there is expected to go back to the production of drinking water barrels is suspect. In some parts of the field, use the “back feed” production buckets no longer a secret.
Some “back feed” is a waste of drinking water barrels, which will directly affect the physical strength of the barrel. Some unscrupulous companies, you will be able to recover to the other PC products, such as discarded CD-ROM, shade, medical blood transfusion bottles, as “back feed” to produce drinking water barrels. They claim to sterilization at high temperatures have been harmless, however, these waste materials which contain additives, is not through the high-temperature decomposition.
Moreover, circulating in the market for individual bucket of raw materials is actually PET. PET is not suitable as a reusable bucket of drinking water and other food packaging materials. However, due to PC import price of raw materials in 3 million yuan per ton, while imports only Liuqi Qian yuan per ton of PET raw materials, some businesses will use this as raw materials to produce a bucket, the harm is self-evident.
Use “back feed” the size determines the level of cost bucket. Therefore, the emergence of the phenomenon of drinking water barrels false, so that the market has entered a water bucket disorderly competition state. Counterfeiters dumping at low prices, making law-abiding businesses struggling to cope with. The city insist on not using a “back feed” the bucket manufacturer, in 2001, a barrel of drinking water use “back feed” the peak years, also had to drastically cut prices, sales of more than 2000 million yuan, profits and very little .
To this end, the relevant departments of those “black bit bucket” implementation of the attack at the same time, consumers in the selection of a time when drinking water, the brand, not only pay attention to drinking water, the brand manufacturers, but also concerned about the quality of a bucket.
