Nanning city plastic wholesale

Nanning wholesale plastic bottle preform quality depends largely on the merits of the PET material, should choose the material easy to blow, easy to finalize the design, and formulate reasonable bottle preform molding process. Experimental results show that the same viscosity of PET bottle preform materials forming, imported raw materials than domestic material for blow molding; And the same batch of bottles billet, production date, blow molding technology may also have bigger difference. Bottle preform quality decides the difficulty of blow molding process, the requirement to the bottle preform is pure, without impurities, no color, length and halo around the injection point. Strong governance under new bureau outlet to brew 'card' on January 17, the ministry issued by the 'tradable permits method ( Trial) 》( Hereinafter referred to as 'method') 。 This reform is to perfect the system of tradable permits another major move, in order to further promote system takes root to lay the foundation.

If carefully read 'much starker choices-and graver consequences-in' ecological environmental planning, many measures and energy structure and related to motor vehicles. During the period of 'much starker choices-and graver consequences-in', hebei and henan, shandong to reduce coal consumption by 10%, and strict controls of motor vehicle emissions. 2, mold temperature. Die temperature directly affect the cooling speed of melting and the degree of crystallinity, degree of crystallinity is different, the plastic pieces of different performance. Usually, the mould temperature control in 100 ~ 140 ℃, when molding thin-wall plastic parts, desirable small value; Thick wall molding plastic parts, desirable value. Injection molding machine: 2, selection of injection molding machine, the law, not more than 25 cm of small appliances, such as electric hair dryer, mobile phones, radios, etc. , can be to any electronics retailer recycling, do not need to buy new appliances; Large electrical appliances such as TV sets, washing machines, refrigerators, the area of more than 400 square meters of large electrical appliances business, or inventory and transit area of more than 400 square meters of online trading electrical contractor is responsible for the free recovery, but the premise is a must at the same time to the retailer to buy a similar function. To this, in recent years, more attention to protection issue. Late last year, China's densely populated a series of environmental policies. At the local, also formulated a series of policies and measures, to strengthen the guide of energy conservation and environmental protection industries. Fujian, for example, actively implement the various preferential policies, including a high and new technology enterprise preferential, comprehensive utilization of mineral resources, etc. , make the industry of environmental protection and energy saving heat up again. For emissions has stipulated special atmospheric pollutants emission limit value in industry and boiler, since October 1, 2018, special executive, nitrogen oxides and particulate matter and volatile organic compounds emission limits. The tradable permits measures ( Trial) 'On January 17, the ministry issued' tradable permits method ( Trial) ', marks the department rules and regulations of our country system of tradable permits. 3, PET material for environmental protection, high barrier property, qualitative light, no broken properties, chemical resistance, sex is extremely strong, but make it white, pearl, colored, magnetic, widely used in hold gels water. Bottle mouth is usually 16 # #, # # 18, 22, 24 diameter, can be used with the pump head. 2, the production profiles: 3, drawing, burning on the lighter when a pull wire, wire pull long is not long, and then pull out the wire break, look at the middle of the breakpoints, silk is rolled into a small circle shape, volume suggests that the more high melting point.
