± PP日本三菱工程FX4G —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.□ TPE苏州吉力士G2701C。
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.
据财新传媒和markit联合公布的数据显示，2018年2月份财新中国通用服务业经营活动指数为54.2%，环比回落0.5个百分点，显示中国服务业活动继续稳健增长，增速略微放缓。包括制造业和服务业pmi在内的2月财新中国综合pmi，录得53.3，略低于1月七年来最高记录0.4个百分点，显示中国经济活动保持强劲增长，增速有所放缓。2月服务业新业务增速出现轻微放缓，但仍保持稳健。受访企业表示，此轮销售增长与新项目执行、拓展新客户有关。制造业新订单量增速较上月略有加强。两大行业综合，新订单量增速连续两个月微降。业务需求上升促使企业增加人手，服务业企业持续一年半温和扩张用工规模，2月增速较1月略有放缓。制造业则连续52个月收缩用工规模，本月收缩率较轻微。综合来看，服务业用工增长很大程度上抵消了制造业用工收缩，整体用工规模与上月几乎持平。2月，服务业积压工作量连续两个月保持大致持平。制造业积压工作量则继续上升，不过制造业工作积压率放缓至5个月以来最低。受此影响，整体积压率轻微，创去年9月以来最低。服务业平均投入成本继续上升，仅略低于1月创下的69个月最高记录。受访企业表示，这与食品、燃料、原料价格和薪酬等投入成本上升有关。制造业成本涨幅放缓至七个月以来最低，但仍属显著。两大行业投入成本涨幅皆放缓，带动综合投入品涨幅降至六个月来最低点。虽然成本压力持续加大，服务业与制造业企业在2月收费价格仅有小幅上升。综合而言，产出价格整体涨幅温和，略有上升。中国企业对未来12个月的前景信心度普遍加强，升至去年6月以来最高水平。其中制造业企业信心度改善至11个月来最高水平。服务业企业乐观度从上月的4个月低点轻微回升，虽较历史数据偏低，但仍然高于制造业。
