Huangshan city cosmetics packaging how to deal with 3, injection pressure. Good PET melt flow, easy molding, usually USES the medium pressure, the pressure is 80 ~ 140 mpa, glass fiber reinforced PET injection pressure is 90 ~ 150 mpa. Should consider the determination of injection pressure, viscosity of PET, the amount and type of packing, the location and size of gate, the shape of the plastic parts, mold temperature, injection molding machine type and size, etc. Netizens suggested: in his provinces hand inside day system, make environmental supervision is a joke, estimates that a village head can keep horses outside his environmental protection inspectorate. Environmental supervision as greedy, shots from the top, otherwise don't say is shut in, is all possible, now the ministry make vertical change, mean right, depends on how much can you please go to the shots, is for the ministry Chen Shangshu worry. 1, cylinder temperature. The discretion of the narrow range of molding temperature and temperature of the PET will directly affect the performance of the products. If temperature is too low, the plasticizing is bad, make the plastic parts such as depression, lack of material defects; On the other hand, the temperature is too high, can cause excessive, nozzle salivate, darker color, mechanical strength drop, even cause degradation. Usually, the cylinder temperature control in 240 ~ 280 ℃, the glass fiber reinforced PET cylinder temperature is 250 ~ 290 ℃, shall not exceed 300 ℃, the nozzle temperature generally 10 to 20 ℃ lower than the cylinder temperature. It is understood that the carbon emissions trading market construction scheme ( Power generation industry) 》( Hereinafter referred to as the 'scheme') At the same time. Carbon emission rights registration and transaction services will be led by hubei province and Shanghai respectively, Beijing, tianjin, chongqing, guangdong, jiangsu, fujian, and to participate in shenzhen. While 'to seek improvement in stability' is the economic herald reporter in one of the key words of conference heard. Even, the pollutant discharge fee reform many times, in charge, to expand the scope, clear the use of special funds at the same time, also through a variety of measures to impose rigid. Implementation in recent 40 years, the pollution charge system of pollution has played an important role, but the fee is low, the lack of a rigid makes our country current pollution charge system deepening increasingly unable to adapt to the ecological civilization construction brings higher requirements. 5, blister and press time: in November 2016, issued by the control of pollutants emission permits system implementation plan, is clear, as the core system of stationary sources in our country, also is the enterprise to obey the law, department, according to the rule of law in society, discharge permit will be effected according to the industry step by step to achieve seamless coverage of stationary sources, and basically completed within four years within the scope of the emission permits issued. B) Color printing fee (boot 800 yuan, Reasonable consumption of 1200 yuan, typesetting and printing, but the unit price. 4, blister mold production and time: this phase is to have been preheated bottle embryo is placed into the ready mold, for its high pressure gas, blow the bottle embryo into the bottle. On September 19, pure and fresh and built 2135 mw ultra low emission reconstruction project officially started. This project is the water power plant after the BOT project, xu again pure and fresh and undertake a xu mining group power plant project. Dragon net environmental protection in the environmental protection industry association released services and niche authoritative ranking in 2016, won the dragon net environmental protection in the field of atmospheric pollution control, a privilege again in September. In general, in the top of the emission permit system design, the future will discharge license system as the core, integrated impact assessment, pollutant discharge total amount control, system of tradable permits and pollution charges, we will establish a unified platform for the fixed source, realize polluters in construction, production, and close at different stages of the life cycle. '2' is the Beijing and tianjin, '26' is in shijiazhuang, tangshan, hebei province, baoding, langfang, cangzhou, hengshui, handan and xingtai, taiyuan, yangquan, changzhi, jincheng, Shanxi Province, jinan, zibo in shandong province, liaocheng, Texas, binzhou, jining, heze city, henan province, zhengzhou, xinxiang, hebi, anyang, jiaozuo, puyang, kaifeng. Selects the mutant with non-return ring tops screw, its surface hardness and wear resistance, length to diameter ratio L/D = ( 15 ~ 20) : 1 compression ratio is about 3:1. Nozzle is good with short, polishing, aperture requirements as much as possible. With hydraulic brake valve type nozzle as well. Nozzle to have heat preservation and temperature control measures to ensure that the nozzle will not freeze. But the nozzle temperature not too high, otherwise cause salivate. Low pressure PP material must be used before began to take shape, the cylinder is clean. Mold is the important factors influencing the PET bottle blow molding process, mold shape quality will reduce or increase the difficulty of technology, such as reinforcement, arc transitional area and at the bottom of the cooling conditions and so on all have an impact on process.
