Yangquan city plastic injection molding process
Yangquan city plastic injection molding process of the phase is to place already preheated bottle embryo is ready to die, for its high pressure gas, blow the bottle embryo into the bottle. Enhance PET melting point 260 ℃, in order to prevent the nozzle blocking, power larger heater should be installed. In addition, the nozzle hole processed into figure - The inverse cone type 1, make the flow channel and the nozzle in the molten material can be easily cut. External ABS PP inside. With a layer of PP gasket. 'Said professor Feng Qiaobin administrative institute economic division. According to university of finance and economics research team, the scale of green taxes will be far more than the current discharge, levy or 50 billion yuan. In addition, considering the local main pollution management responsibility, later will protect all as local income tax, no longer involved in. Common drained, is through the ABS ( Assets) Will project franchising period of future earnings, such as shares issued 'citic - Stake in sewage disposal PPP project charge of remuneration asset-backed special plan '. ABS is not something new, similar products such as real estate REITs ( Real estate trusts) And so on are very molding, but in the environmental protection industry has just started. Industry development policy of good soil repair soil problems, strengthening the concept of risk control is a matter of opinion whether to 'eat', 'live at ease,' with the top-level design of ecological civilization construction in our country is increasingly perfect, the soil has become an important content of governance, is one of the three big battle of pollution, restoration of the soil is in focus. We believe that the environmental protection supervision upgrades, emphasis on 'government environmental responsibility', has been clear about the achievements and the principle of protecting link, help the local committee and environmental protection consciousness, avoid departments responsibility, environmental supervision to the management rate and high execution. Considering the future assessment of environmental governance in local weight increase, the future will be more local environmental management at all levels. 2. Heat 2 blow molding processes of PET plastic profile: China energy conservation and environmental protection manager Lv Jiawei said, energy conservation and environmental protection industry long-term growth space, contains a large number of investment opportunities in future environmental sector including the bulk of industrial solid waste disposal, sludge disposal, VOC governance, living garbage incineration, urban sewage treatment, sewage treatment in rural areas, soil restoration, black smelly water governance has some investment value. 'Cat and mouse' environmental protection problems, how to break the environment minister ji-ning Chen promises, will strengthen the linkage, administrative and criminal justice for the further enterprise become the norm. 'Continue to protect the implementation of activities, increase the investigation dynamics of major cases, industrial pollution sources must be within a time limit, overdue shut down in accordance with the law, for all the key pollution sources on-line monitoring 24 hours a day. However, they are used by promoting public - in our country The result of cooperation as the PPP. So, false the popularization and application of PPP in the PPP, makes efforts to reform the public sector itself is no longer concern for everyone. So that the current PPP delay infrastructure construction and social undertakings investment fields become important tool of further reform, we can't avoid this problem. Industries with good effect to reduce emissions can also ''. Energy news has reported that an operator to calculate bill: in March, the enterprise surplus index 88 kilograms, chemical oxygen demand (cod), ammonia nitrogen, 134 kg, 990 kilograms in accordance with, the net sales to sell at least 5575. Eight yuan. According to estimates, about profit 6 all the year round. 70000 yuan. Pilot provinces to strive to be completed by the end of June 2017 pilot work, not included in the pilot areas strive to be completed by the end of June 2018 below the provincial level protection system. 'From the perspective of the big background of ecological civilization system reform to the vertical change, in the spirit of all the important documents since from understanding the vertical change and promote change. Because the PET macromolecular contains aliphatic, has certain hydrophilicity, aggregate compared to water at high temperature, when the moisture content is more than the limit, in the processing of PET molecular weight drops, products with color, crisp. Trapped here, in front of the processing must be carried out on the material drying, the drying temperature is 150 ℃, more than 4 hours, generally is 170 ℃, 3 - 4 hours. Air-launched available to test whether the material completely dry. Injection molding in is mainly used to enhance the PET molding. Usually adopts screw injection machine. Screw is typically require hardening treatment, lest abrasion occurs after use for a long time. The length of the injection machine nozzle holes should be as short as possible, its diameter should be controlled at about 3 mm. 9, production production bag when compounded by high temperature, relatively clean, no special when filling.
