Fumed Silica VIPs For Refrigerator
Core + film covering
The core of the insulation panel consists of pressed powder, whose main component is micro-porous silica. Other components include opacifiers to minimise infrared radiation, and cellulose fibres to improve mechanical stability.
Vacuum insulation has a long service life
The panel core is non-flammable and has been assigned fire class A1
Vacuum insulation panels (VIP) do need significantly less space than conventional insulation (such as mineral wool) material. Our panels only need one fifth of the thickness of conventional insulating materials to achieve comparable insulation values. In both cases the core material is wrapped in a metal coated foil and the air inside was evacuated. Of course the goal of both applications is different. The evacuation process is reducing significantly the heat conductivity of the panel.
The core material of high quality vacuum insulation panels mainly consists of silica (preferably fumed silica). Cheaper VIPs contain glass fibre as core material. Unfortunately these VIPs do have tremendous ecological and technical disadvantages
With thermal conductivity 4.5mW/mk, it would take approximately 175mm of traditional insulation wall thickness to equal the Vacuum Insulation Panel`s 25mm thermal efficiency.

The 62nd Commercial Vehicle Expo is held at the Hannover Exhibition Center. It has the world's largest exhibition hall, 27 exhibition halls, and an indoor exhibition area of ​​498,000 square meters. It also provides 58,000 square meters of outdoor exhibition space. Because of concern for public transportation, the author paid special attention to the discovery of 76 bus and bus manufacturers and 176 component suppliers. In addition to the world-famous manufacturers, I also saw some unknown bus and bus manufacturers. For example, Alga, AMEX, CONTRAC, ProBus, and KORMAS, OT-SA, etc. from Turkey are specialized in the manufacture of small and medium buses. The previous information shows that some old bus and bus manufacturers have closed down or switched to their production facilities in Western Europe and saw these new manufacturers, especially the various advanced models on the show, and the old-fashioned buses and buses of different eras. (To occupy a pavilion), the author truly feels that the bus and passenger car manufacturing industry is a sustainable industry.
The theme of this year's commercial vehicle fair is to improve transportation efficiency, reduce fuel consumption and carbon dioxide, and the most prominent highlights are hybrid models and products. Duff and Cummins exhibited a hybrid system particularly prominently; ZF and Meritor also exhibited hybrid drive axles; Mercedes-Benz, Mann, Volvo, Van Hul, Issa Bus, Solari Bus, VDL And so on, they have displayed advanced hybrid buses... In today's high global fuel prices, reducing energy consumption and reducing exhaust emissions have become the goals pursued by manufacturers for R&D.
We communicated with Wolfgang Schaer of ZF AG in Germany about energy-saving emission reduction technologies and products. From the company's new products at the show, we can clearly feel the momentum of hybrid technology development. Prior to this, he had the opportunity to visit the headquarters of the international auto parts manufacturer in Friedrichshafen, the transmission factory, and the axle factory in Passau. He also tested and equipped the automatic transmission at the company’s test ground. The buses and trucks of automatic shifting mechanical transmissions admire the rigorous and pragmatic style of German industry.
Jinlong Bus not only appeared at the Commercial Vehicle Expo in Hannover, but also had vehicles in operation on the German market. Talking with Xu Xiangdong, deputy general manager, everyone was full of confidence in the international marketing of Chinese buses and buses. Compared with large international companies, Chinese manufacturers also need to accelerate the pace of expansion in the international market. More importantly, they must integrate into Europe and the world.
At the Setra bus booth, see Had Landman, president of Aiva Bus Company, who is responsible for the production and sales of the two passenger car brands of the Daimler Group’s Seletar and Mercedes-Benz. Similarly, at the Volvo booth, we also saw the general manager of the bus division. Almost all the bosses of big companies appeared on the show floor and communicated with customers. Relatively speaking, the owners of the manufacturers were rarely seen at domestic exhibitions. Most of them did not see their faces and did not use the show to communicate.
Two interesting "non-professional" incidents are worthy of attention in the Chinese report on this year's commercial vehicle expo. One reporter described the coverage of nearly 300 square meters of stand of China FAW Group as a "big booth". In fact, in the exhibition area of ​​275,000 square meters in 15 exhibition halls of the Hanover Commercial Vehicle Expo, the exhibition booth in this area is fundamental. It is not suitable to use any "big" word to describe. When you enter the booth of Mercedes-Benz company occupying the entire Hall 14-15, you will experience what is "big" in the booth where Niemann and Volkswagen jointly occupy Hall 12. "The booth", I hope that reporters can objectively spread the status of the industry to the Chinese public, with more international perspectives, and less a bit of egoism.
Another reporter reported that the German Selterra S415NF won the "2009 Bus Award." In fact, this is a low-floor urban bus model, and the correct understanding of the grand prize should be the "2009 Bus Grand Award." In the European bus and passenger car manufacturing industry, two awards are awarded every two years, namely the “Bus of the Year†and the “Bus of the Yearâ€, which award models that have made major contributions in the fields of tourist bus and urban public transportation, and are in Germany every single year. The annual Bus Awards presented at the Hannover Commercial Vehicles Expo are the annual Bus Awards presented at the Kortrijk Bus World Expo in Belgium. I have been advocating the use of buses and buses to replace the term "bus" that was used widely in the past because it is a more common term in the international community. Bus (Bus) refers to buses that operate in cities, while coaches (COACH) It is a model that operates or travels between cities.
