·Beijing V emission standard implementation of supporting supply of Beijing V fuel during the year

<

The Beijing V vehicle emission standard will be implemented this year, and it will supply the Beijing V standard vehicle fuel. According to informed sources, the Beijing V standard is similar to the national V emission standard, but some aspects have raised higher requirements. Once Beijing fully implements the Beijing V emission standard, it means that vehicles that do not meet this emission standard cannot be sold in Beijing.

The relevant person in charge of the Ministry of Environmental Protection said that the national V standard will be released and implemented this year. Before that, Beijing will implement a Beijing V emission standard similar to the European V standard. It is reported that the petrochemical sector has successfully produced the supporting supply of Beijing V standard gasoline. According to the national V standard, the sulfur content of gasoline and diesel is further reduced from 50 ppm of the national IV to 15 ppm. According to informed sources, the sulfur content of Beijing V standard gasoline will be reduced from 50ppm to 10ppm, and environmental protection and other indicators will rise to a very high level. More importantly, due to the improvement of oil quality, the combustion is more sufficient, and the PM2.5 emission in the exhaust gas can be directly reduced.

Beijing has been implementing national standards in advance, the implementation of the National I standard in 1999, and the implementation of the National II standard in 2002, both of which are two years ahead of the rest of the country. At present, Beijing implements the national IV standard for motor vehicle pollutant emissions. According to sources, the Beijing V standard puts higher requirements on emission limits for vehicle emissions such as nitrogen oxides and hydrocarbons. “Even some standards will be higher than the national V”.

Jia Xinguang, a senior auto analyst, pointed out that for the automotive industry, the new standard will test the technology of engine manufacturing, and new Equipment, technology and personnel will be needed for the detection of emissions. These factors will increase the cost of the vehicle to a certain extent. . According to insiders of the car company, the emission test fee for a new car reached 2 million yuan.

The reporter's investigation found that most auto manufacturers have prepared for technical upgrades for the upcoming national V standard. As for the Beijing V standard, most dealers are still unaware of it, but they said that according to historical experience, the new policy may be notified in advance of the implementation time, or after the launch, the dealer will be adjusted for a certain period of time. “I hope that time will be more abundant. After all, the dealer needs a process to digest the inventory vehicles.”

Hot Melt Adhesive For Shoe

Hot melt adhesive for shoes refers to a general term for a class of hot melt adhesive products used in the field of shoe processing, which is not a single model of hot melt adhesive film products. Due to the diversity of shoe-making materials, there are many types of hot melt adhesives used in the field of shoe materials. To make a simple summary, the common types of tpu hot melt film with low temperature release film, and the types of pa and tpu hot melt omens.

So, what are the characteristics of using hot melt adhesive as a adhesive for shoe materials compared with traditional white glue and yellow glue? The characteristics of hot melt adhesive for shoes compared with traditional shoe adhesive are mainly in the following aspects:

1, more environmentally friendly than traditional adhesives, both for the production of operators, or consumers are more healthy;

2, better air permeability: especially for shoes with high air permeability requirements, the air permeability of hot melt adhesive will be better than traditional adhesives;

3, better bonding strength: from the perspective of the composite effect, the bonding strength of hot melt adhesive is better than that of traditional glue;

4, from the production point of view: hot melt adhesive is easy to continuous operation, can greatly increase the production efficiency of the enterprise.
