Fumed Silica VIPs Core Materials
Vacuum insulation panel consisting of fumed silica core material have two major parts: fumed silica core material and high barrier laminates. As a special composite made of core materials and protective film, integrated with the superiority of vacuum insulation and micro-pore heat insulation, effectively stopping convective heat transfer to perfect thermal insulation. With a thermal conductivity of lower than 0.0045w/m.k and minimum thickness of 5mm thicknesses, vacuum insulation panel based on fumed silica core material uses fumed silica core materials with a higher expected lifetime and the environmental protection materials that can be recycled and reused.
The best way to utilise the high insulation value VIPs is to ensure they have been fully encapsulated/protected at the manufacturing stage, thus eliminating the risk of puncture during installation and use.
IPs have widespread use in specific technological sectors where their performance is not affected by their delicacy and poor versatility, as in manufacturing of cold-storage cells, electrical appliances, and in particular containers for the transport of low-temperature material, in which the high performance with low thickness and weight give advantages for reduced payload users such as carriers of air cargo.

Diesel engines are linked to "high pollution" in people's minds. They have insufficient combustion and are noisy. These innate technical disadvantages make consumers seem to have a dirty model of it.
For the automotive industry, it is more affected by environmental protection than any other industry. Every new environmental protection policy and emission standard will be inextricably linked to automobile manufacturers and the market. Manufacturers' innovation in products is also based on technological innovations that increase environmental protection requirements, and even the competitive landscape of the auto industry is It may change as a result.
The era of big fish eating small fish is over. Now is the time when fast fish eat slow fish.
Cummins is clearly the biggest fast fish in China's emerging environmental protection engine market. At the 8th China International Combustion Engine Exhibition held on October 21st, a total of 11 engines were exhibited on the Cummins booth. There are two major categories of diesel engines and natural gas engines, among which the automotive diesel engine meets all the latest national III and national IV standards. Emission Standards.
Connection bus
Wang Hongjie, vice chairman of Cummins (China), spoke confidently and candidly on the 21st when interviewed by "Car Watch" magazine reporter: "Cummins is always implementing green environmental protection."
Wang Hongjie recalled that the large-scale introduction of Cummins environmental protection engines can be traced back to 1998, when Beijing Public Transport was preparing for a natural gas bus project. The first batch of natural gas engines equipped with 300 Cummins, is now on the 1st and 4th roads to Chang An Avenue. A bus line.
Since 1999 was the 50th anniversary of the founding of the Republic, the central leadership attached great importance to environmental issues and hoped that the air in Beijing could be cleaner. Efforts to establish a clean and environment-friendly city bus fleet and China’s abundant natural gas reserves were made. Beijing Bus began to look for engines in various countries. At the plant, when they found California, California had the strictest engine emission standards for the world. They saw a large number of Cummins engines. Undoubtedly, Cummins natural gas engine technology has become the most ideal choice for Beijing public transport. In 1998, it was tested. In 1999, it introduced more than 1,000 units. So far, more than 3,000 Cummins natural gas engines have been put into use in Beijing.
The pace followed is always in the footsteps of the best. In 2004, cities such as Beijing, Shenzhen, Guangzhou, and Shanghai advanced the schedule of Euro III emissions. The market capacity of environmental-friendly urban buses was rapidly expanded, indirectly creating a huge market opportunity for Cummins.
In order to reduce the cost of natural gas engines, in the first half of 2005, Cummins achieved localization of natural gas engines at Dongfeng Cummins.
Fast fish era
In fact, as early as 1996, Dongfeng Cummins launched the Euro I standard engine at the time of its establishment. At that time, there was no domestic emission standard for the engine.
Since 2001, Cummins has been ahead of the industry and has taken the lead in bringing the full range of ultra low-emission vehicle engines to the European, American and Chinese markets to meet European environmental standards III. At that time, China's emission regulations only required the full implementation of Euro II emissions by 2005.
Cummins's Dongfeng Cummins has already formed two diesel and natural gas platforms, with 4.5 liter, 6.7 liter, 8.3 liter and 13 liter four displacements, meeting the two major emissions of State III/State IV and Euro III/IV. In addition to satisfying the domestic market, the laws and regulations, in combination with Cummins's strong global after-sales support system, have become the first choice of environmentally friendly power for domestic major commercial vehicle companies to export models overseas. The products are exported to Russia, Eastern Europe, South America, the Middle East and Africa and other international countries. market.
Xi'an Cummins Company is not far behind. Although it was formally put into production in 2007, but at this year's exhibition, they also handed over a satisfactory answer and exhibited a new generation of ISM 11 litre all-electronically controlled heavy-duty diesel engines meeting the national IV/EU IV emission standards. The adoption of an SCR selective catalytic reduction post-treatment system is 5% higher than the previous generation III engine and is expected to be put into production in 2009.
The new-generation ISM 11-liter fully electronically controlled engine has passed the dual emission standard certification of the European Vehicle Certification Authority (VCA) and the China Automotive Quality Supervision and Inspection Center. It is the first European-European heavy-duty diesel engine to pass the European emission certification and is easily upgraded. Fifth, the technical capabilities of China's heavy truck companies will break through the environmental protection barriers in Europe and the United States, and move toward the high-end international market.
Wang Hongjie also introduced: "The Cummins Exhaust After Processor will be put into production in Beijing in 2009." By then, its four key component systems (air intake processing, filtration, fuel, and post-discharge processor) will achieve localized production, not only It supplies Cummins four joint venture engine plants in China, and also with major domestic diesel engine companies including Weichai, CNHTC, Yuchai, Xichai, and Dachai.
Waving clean energy
At the end of the 1990s, diesel engines were once subjected to "discrimination" and many cities introduced a ban on diesel vehicles. For this reason, Cummins and multinational corporations including Daimler, AVL, Honeywell, MAN, Bosch, as well as domestic FAW, Second Automobile, Yuchai, Weichai, etc., have successively joined a so-called “green diesel organizationâ€. It is an unofficial non-government organization aiming to promote new developments and advances in the environmental protection and performance of diesel engines in recent years.
As early as the mid-1990s, Cummins began to focus on the research of hybrid technology. Currently, Cummins hybrid diesel engines have been used in bus fleets in the United States, Canada, the United Kingdom, and China.
On September 2, 2006, Xiamen Jinlong demonstrated the XMQ6116G8 hybrid electric city bus equipped with the Cummins ISBE fully electronically controlled engine.
In October of the same year, Cummins signed a cooperation R&D program with Tsinghua University to use its unique advantages in the fields of production and learning to conduct comprehensive R&D cooperation in engine and hybrid technologies.
Since then, Cummins hybrid power market, and Shanghai Shen Wo, Xiamen Jinlong, Futianou V and other host plants have further cooperation.
In the just-concluded Beijing Olympics, 60% of the T1 Olympic dedicated hybrid buses use Dongfeng Cummins's State IV diesel engines; and 300 Dongfeng Tianjinzhongka equipped with Dongfeng Cummins III engines are part of the Beijing Sanitation Group's sanitation team during the Olympics. The main model.
Cummins' brand slogan "Clean Power Services China" also makes this company with more than 60 years of origin in China carry the social responsibility.
For the present China, solving the problem of environmental pollution is imminent. The country has put forward the strategic thinking of "sustainable development". As an important part of social citizens, enterprises also have unshirkable responsibility for environmental protection.
Cummins' goal in environmental protection is to become a global "corporate citizen." They continue to develop advanced power products, and also improve fuel economy. They are far ahead of the increasingly stringent engine exhaust emissions and noise standards worldwide.
As Wang Hongjie said, “serving China†is not a simple slogan, but it is the concept that is transmitted to enterprises, their associated supporting companies and partners.
Cummins has more than 5,000 distributors in 190 countries, with the power of the Internet and the brand effect of more than 90 years. Cummins is redouble its efforts to promote the technological level and global recognition of many industries together with China in the image of its "green pioneer."
VIP insulation is also viable for low-temperature applications such as refrigerators, water heater, cold chain, building, water purifer with fumed silica core panels.
