∩ PP辽宁华锦化工T30S╳When fire is flammable, the flame is yellow, there is a drop of paraffin like oil when burning, and the gas when the candle burns, it is nontoxic polyethylene film bag. If it is not easy to burn, the fire is extinguished and the flame is green. It is a PVC film bag.*** ETFE 日本旭硝子 AH-3000L╇
When the plastic bags are immersed in water, and the water is pressed by hand, the surface can be covered with polyethylene. The density of polyvinyl chloride is lower than that of water, and the density of polyvinyl chloride is greater than that of water. When the temperature is about 0.92g/cm3 and 1.4g/cm3 respectively,
A copper wire is also used to burn red in the fire. Then copper wire will be contacted with the test plastic film to produce chemical changes, and then the copper wire dipped in the plastic component will be put back into the flame. At this time, it is necessary to observe carefully, if there is a colorful and dazzling green flame, it shows that this plastic material contains chlorine, and it belongs to PVC.
Main harm
A plastic PVC is often used, it is made of PVC resin, plastic resin increasing agent and anti-aging agent, and non-toxic. But the addition of plasticizer, antioxidant and other accessories are toxic, daily in PVC plasticizer, mainly using terephthalic acid two butyl phthalate two formic acid two ester etc., these chemicals are toxic, lead salt antioxidant stearic acid polyvinyl chloride is toxic. Lead salt antioxidant of polyvinyl chloride (PVC) products and ethanol, ether and other solvent exposure will lead precipitation. Lead salt of PVC as a food packaging and Deep-Fried Dough Sticks, fried cake, fried fish, cooked meat products, cake snacks foods to meet, will lead to molecular diffusion into the grease, so can not use PVC plastic bags containing food, especially food containing oil. In addition, polyvinyl chloride plastic products will decompose hydrogen chloride gas slowly at higher temperature, such as 50 degrees Celsius, which is harmful to human body. Therefore, PVC products are not suitable for food packaging.
