The material of the solar cell should consider the value of the band gap, and at the same time, it can absorb the sunlight to the maximum. At this point, neither monocrystalline silicon nor polycrystalline silicon can be preferred. However, the following factors cannot be ignored when choosing materials. First, the material is easy to obtain and non-toxic; second, the battery preparation process is simple, repeatable, and convenient for mass production; the material must also have long-term...

The so-called silicon pump, in fact, refers to aluminum zinc silicon pump. Aluminum zinc silicon pump, refers to the pump impeller, shell, gland and other major components are all corrosion resistant alloy steel - aluminum-zinc-silicon alloy. Al-Zn-Si pump can effectively control the zinc liquid in the pump flow rate, temperature drop, thermal expansion coefficient of the material and other indicators to meet the special requirements of repeated use for a long time, therefore, aluminum...
1. Before the first operation, sufficient fresh water must be added to the equipment and no empty machine is allowed to operate; 2. When the metering pump stops feeding, the ejector should continue to operate for more than one hour, so that the chlorine dioxide gas in the reactor can be fully evacuated to avoid gas overflow from the inlet pipe. 3. If the power source suddenly stops water, the metering valve should be closed immediately. 4. Hydrochloric acid is a strong acid. Operators should...

The carbon dioxide monitor developed by Zhejiang Top Instrument uses advanced SCM technology and non-dispersive infrared gas sensor (NDIR) technology, featuring high measurement accuracy, long service life, and easy operation, and is suitable for detecting carbon dioxide gas in various working environments. concentration. The basic principle of the non-dispersive infrared sensor is that gas molecules absorb infrared light of a specific wavelength, and the absorption relationship obeys the...
Apart from the need for sunlight and water, photosynthesis also requires sufficient carbon dioxide. The most suitable crop for carbon dioxide concentration is 1‰-1.5‰. The concentration of carbon dioxide in the air is 0.4 ‰. In greenhouses and greenhouses, due to the constant absorption of vegetables, the concentration of carbon dioxide is only 0.1 ‰, which is far from meeting the needs of crops. Therefore, adding carbon dioxide gas fertilizers will become an important measure for increasing...
The increase in raw materials prices in various industries will have to start at the end of 2016.

Recently, under the weak recovery of the world economy, the U.S. economy has benefited from the world’s currency status, and the economic recovery is good. As the U.S. gradually withdraws from the quantitative easing policy and the strong return of the U.S. dollar, the outflow of capital and the expected depreciation of the renminbi will intensify. The conclusion of the TPP agreement will further aggravate the already declining Chinese economy. The market conditions of chemical products are...
Only to oxygen, silicon is the most abundant element in Earth's crust. It is found in rocks, sand, clays and soils, combined with either oxygen as silicon dioxide, or with oxygen and other elements as silicates. Silicon's compounds are also found in water, in the atmosphere, in many plants, and even in certain animals. Silicon is the fourteenth element of the periodic table and is a Group IVA element, along with carbon germanium, tin and lead. Pure silicon is a dark gray solid with the same...
