According to iSuppli's latest forecast, the global PV installed capacity forecast for 2011 will reach 22.2GW. In the traditional market in 2011, Germany is leading the way with 9.5 GW of new installed capacity, Italy is close to 2 GW; Czech installed capacity will decline; France's installed capacity will drop from 1080 MW to about 700 MW. In emerging markets, the US has grown from 1GW in 2010 to 2GW; China's new installed capacity is expected to expand from 400MW to 1GW. The launch of emerging markets can compensate for the shrinkage of some traditional markets in Europe. It is expected that the global installed capacity of photovoltaics will still maintain a growth rate of 30% in 2011. Coupled with the gradual application of diamond wire to the cutting of IT wafers and LED sapphire, the demand for diamond wire is bound to increase sharply. According to an authoritative structure survey, the potential market for diamond wire saws in China is currently 8 billion US dollars. The diamond wire is mainly used for the cutting of silicon wafers necessary for photovoltaic and IT industries. According to the research and analysis of the largest silicon wafer company in China, GCL, the diamond wire has been widely used in the silicon ingot manufacturing. The application of diamond wire is of great significance to the wafer factory. Wafer processing costs 27 cents per watt, with a cutting cost of 20 cents. Therefore, the technical breakthrough of the cutting line is the most important way to reduce the cost of wafer processing. Diamond wire cutting speed is twice that of ordinary steel wire, so the depreciation, labor and energy costs per unit of production will be reduced by half. It is understood that the diamond wire cutting process has been popularized by more than 90% of users in Japan, and is used by more than 20% of users in Europe and America. At present, the domestic diamond wire market is mainly monopolized by foreign companies. China's manufacturing is relatively blank, and the imported diamond wire is expensive, which seriously affects the wider application of diamond wire. Fortunately, domestic diamond companies such as Yu Diamond are building diamond line projects. I believe that the prosperity of China's diamond line will soon come.
What are the characteristics of EPS Sandwich Panel ? What are the advantages of using it?
EPS sandwich panel are used in many buildings. The advantages of using this type of panels are obvious, and the price is also very favorable. There are many simple Prefabricated K House and Steel Structure Warehouse that use this type of board, so what are the advantages of its use?
low thermal conductivity
Because the thermal conductivity of EPS itself is relatively low, its effect as an insulation material is also very good, it can ensure the indoor temperature, and can also achieve a good energy-saving and environmental protection effect. It is precisely because of its good thermal insulation ability that under the same thermal insulation requirements, it can effectively reduce the thickness of the outer wall of the building and increase the internal usable area.
Good moisture-proof effect
Because the closed cell rate of the EPS sandwich panel reaches more than 95%, it is a kind of hydrophobic material, so there will be no moisture, and there will be no water seepage on the wall, which can ensure the reliability of the long-term use of the panel. . The Rock Wool Sandwich Panel is more susceptible to moisture.
Fire retardant effect
This type of material is resistant to high temperatures and also has very good fire resistance. Fire rating B1. And after a certain amount of flame retardant is added to its material, even if a fire occurs, it can also avoid natural disasters. Decomposition will only occur when encountering high temperature, and a carbonized layer is formed on the surface, and the safety of long-term use is also guaranteed.
strong security
The EPS sandwich panel has strong anti-deformation ability, and it will not be deformed or cracked after long-term use. Moreover, its installation stability is guaranteed, there will be no problems such as falling off, and the safety of long-term use is also guaranteed.
good sound insulation
Because the structure of this kind of board is stable and basically closed-cell, it can not only keep warm and waterproof, but also has a good sound absorption effect, and the sound insulation effect is also guaranteed.
Price concessions
Compared with other boards, EPS sandwich boards are cheaper in price and have a variety of properties, which is also very good in terms of cost performance. Therefore, if you want to ensure that the construction cost is favorable, then this type of sandwich panel is also very worthy of our choice, which can save a lot of construction costs.
