Baiyin external internal PP ABS plastic container manufacturer.
With a layer of PP gasket.
If the mould temperature control is not good or improper material temperature control, easy to produce white mist and not.
Die temperature low and uniform, cooling speed, less crystal products.
5, non-woven fabric containing chemical fiber composition is easy to cause the user skin, so don't advocate using, less use of other materials.
For two years, from give priority to in order to check the enterprise into a 'check overseers simultaneously, mainly DuZheng', the local department of ask obliged 'sword' for environmental inspectors this drawn after the true face difficult problems.
Environmental supervision is deep place a knife 'sword', provides clear all kinds of protection.
With clear water source and the Oriental garden as an example.
According to the water source after half annual report, released in the first half of 2016, clear water source operating income of more than 2 billion yuan, increased by more than 110%.
For performance reasons for the soaring, clear water source will climb performance thanks to continue the unique PPP, to enterprise's market share.
It is not hard to see, the two ministries joint investigation data, there is no doubt that shows the current our country soil polluted degree should be against, the soil pollution problem has become increasingly serious.
According to the relevant department statistics show that soil every year 12 million tonnes of grain in China by the soil heavy metal pollution, loss of up to 200 a year.
In ecological gradually turn to good at the same time, the environmental protection industry strong rise, the same rich and famous.
From the development trend of environmental protection industry, from small to large scale, industry bigger and stronger by trend has become increasingly obvious.
Various capital to environmental layout, more businesses across borders.
In an increasingly 'gold' environmental protection plate, capital for more and more fierce, the release of market demand scale of the industry, market demand is higher and higher.
3, the 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.
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 -
Air-launched available to test whether the material completely dry.
Under normal circumstances, if the time order, about five days after confirm the sample delivery, for the second time delivery to three days.
'The report stated that protection will be in accordance with relevant provisions of the action plan for water pollution, in conjunction with relevant departments, to overdue built sewage concentrated treatment facilities or not according to stipulations to install automatic online monitoring device of industrial agglomeration area, to suspend the examination and approval and approved construction project for water pollutants discharge, in accordance with the relevant regulations, revoke the park such as the qualification punishment measures.
Set sail at the beginning of emission permits, bring change on November 6, the ministry review and principles through the 'tradable permits method (
', carry out promoting system of tradable permits.
As of the end of June this year, thermal power, paper 5190 licenses issued by the two industries, issued by the work done.
In hebei, 460 thermal power, pulp and paper industry enterprises, 178 companies because they do not comply with the requirements for certification by 'bright red light', may not discharge.
Building charging pile were buzzing new energy cars, especially in the fuel cars to ban or will become a reality in the near future, the electric car has received widespread attention.
But because part of consumers, the difficulty of charging has decided to buy, if charging pile available performance enough to cover all building?
Help the future of new energy vehicles development in line with the green building choice, installation of charging pile and supporting facilities is becoming a problem.
'' area all the way to build a highway ecological environmental protection.
As the only way for enterprise transformation, the ancient silk road is also the whole dynamic of the green industry blue ocean.
'Area' all the way along the region economic development is extensive, relatively fragile ecological situation has become the bottleneck of the region can develop, but also for the region to carry out economic and technical cooperation in the field of green development provides a rare opportunity, great potential and broad space.
As over the 'hot topics', environmental protection topic again detonate market: 'resolutely play blue sky battle' express not only further upgrade, the green development strategy and environmental protection industry in the future capital market will be the emergence of huge investment opportunities.
Guangfa green environmental protection index ETF and guangfa, follow the policy is focused on the environmental protection industry, mining in resources, clean technology and products, growth, value and provide investors with long-term share packaging industry growth income of investment tools.
2, double tube is relatively common, also can use single layer belong to medium, hose diameter for 13 # -
60 # a variety of caliber, elected a certain diameter of the hose, the capacity of different characteristics in different length, capacity of 3 ml -
360 ml can, in order to beautiful and coordination, the calibre of the commonly used below 35 # below 60 ml, 100 ml, 150 ml usually use 35 # -
45 # caliber, more than 150 ml capacity is more than 45 #.
5, the production cycle is commonly 4 to 5 days, the cartons are occupied location, suggested that small batch order and inventory of the agreement.
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.
