Three hezhou cosmetics packaging manufacturer, nozzle, emulsion pump, pump to wash your hands and length measurement as to implement the work content is more environmental protection, and there are the facts of the environmental protection departments to punish or problems is down or not.
At the same time, most of the policy of subjectivity is stronger, is subjective general language, seemingly, but did not clear responsibility implementation mechanism.
L/D is too big material within the cylinder for a long time, heat is easy to cause the degradation, affect the product performance.
Compression ratio is too small shear heat generating less, easy plasticizing, product performance is poor.
Vice can make glass fiber fracture, more mechanical performance degradation.
When processing glass fiber reinforced PET and cylinder wear more severe, cylinder use wear-resisting material or have wear-resisting lining material.
'900 tons a year green plants can release oxygen, it is enough to one breath in 95.
With the popularity of the concept, 'vertical forest', but also more and more attention.
Nature is a problem concerned by many people.
Vertical structure of forest part of public information, on the basis of the original design to complete the piling, have to has carried on the structure calculation, the requirement of load after planting trees, fully guarantee the overall load demand and the overall structure.
Its inception, sinopec, energy conservation, environmental protection, executive director and general manager zhang jian, said the aim is to implement the low carbon environmental protection, the blue sky blue water strategy, through the integration of the group advantage, main environmental protection business.
Conclusion from the point of policy trends, environmental protection industry growth is beyond doubt.
Is, therefore, to the future, the environmental protection industry will attract many market participants.
PET of vitrification transformation temperature about 165 ℃, the crystallization temperature range is 120 ~ 220 ℃.
PET at high temperature has a strong hygroscopicity.
For glass fiber enhanced PET material, also very easy to bending deformation at high temperature.
Can enhance agent to material by adding the crystallization degree of crystallization.
With PET processing of products has the gloss and heat distortion temperature.
Can be added to the PET mica and other special additives reduce bending deformation.
If you use a lower mold temperature, then the use of filling material of PET products.
Earlier this year, the ministry announced the pollution plot soil measures (
'Soil', further ten 'extension and refinement, clear the responsibility.
In addition, the network has been basically completed, to deploy 40000 monitoring points, reflect the status of soil and the change trend as a whole.
With a series of policy, the industry have said in the short term soil monitoring and investigation will have big market.
1, silk screen as packaging products in general graphic identity processing working procedure, has important influence to the product image, so higher requirements on the technical aspects.
6, the selection principle of materials, large area with 40 g to 80 g of whole viscose or blended, stick a small area with more than 60 g, such as eye, nose film, etc. , the specific planning of the products as the guidance.
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.
PPP, as it were, in addition to the domestic developing, with the aid of dongfeng 'area', has become the focus of attention.
Since this year,,,, the securities and futures commission, the China banking regulatory commission and other departments have issued documents, provide new support for the PPP in policy.
'It can be said to promote work in the PPP asset-like has special meaning for the further development of the PPP, for the PPP to absorb more social funds to participate in making important layout.
Project 4: beijing-tianjin-hebei atmospheric pollution to the health of people and the surrounding areas influence study 1, beijing-tianjin-hebei, and surrounding areas of atmospheric pollution on the people in the general population, specific acute health impact study;
2 the weather, heavy pollution influence to the health of patients with copd and etc;
3 the weather, heavy pollution and at higher risk of health effects in patients with cardiovascular research;
Four main attribution, atmospheric pollution risk and burden of study;
5 the weather, heavy pollution.
Of course, draw a red line is the foundation, adherence to the ecological protection of red line is the key.
In other words, the Red Cross to set, more to keep up.
Therefore, for the place, to know height, deal with the contradiction between long-term and short-term development, to ban, and encourage to have specific provision.
So, how to keep the ecological protection red line?
PET recycling of large capacity with glass, because the store for a long time, suitable for small capacity of PP short-term storage.
Most no perfume PCTA and PETG.
1, when designing type plastic bottles, if the material is high density polyethylene or polypropylene, plastic bottles of cross section should be rectangular or oval, low density polyethylene or other flexible material for plastic bottle, its round cross section as well.
Such facilitating contents from out from the plastic bottles.
Used with plastic bottle of the plastic parts mainly for cap and seal.
Should focus on the design of the plastic bottle, about how to make the plastic bottle can better with the bottom of the cover and sealed with plastic bottles, plastic mechanics performance of weak positions.
Therefore, the plastic bottle at the bottom of the general design into inside concave.
Plastic bottles of the corner, and inner sunken place, all do larger arc.
Piled up for ease of plastic bottles, plastic bottles of stacking, plastic bottles should be designed at the bottom of the groove.
