Carbon Dioxide Remover In the process of adjusting the atmosphere, it is generally required that the concentration of CO2 be controlled within the range of 1 to 5%. The respiration of fruits will increase the concentration of CO2 in the reservoir. When the concentration is too high, a CO2 remover (also called a scrubber) must be used to remove the excess CO2 in the reservoir to reach the optimal range of the parameters for the gas conditioning. Now CO2 removal machines produced at home and...
Monocrystalline silicon material is a crystalline silicon material for very traditional Chinese medicine shops. According to the different growth patterns, it can be divided into single crystal silicon and single crystal silicon. Single-crystal silicon is mainly used in high-power devices, accounting for only a small part of the monocrystalline silicon market, accounting for about 10% in the international market; and Czochralski silicon is mainly used in microelectronic integrated circuits and...

According to a special report, it is expected that the application of titanium dioxide (Ti02) in plastics will increase by 3.2% in 2003; plastic remains the most important and largest market for titanium dioxide. The company predicts that, at least until 2007, the market demand for titanium dioxide as colorants, opacifiers and self-stabilizers for PE, PP and PVC will grow at an average annual rate of 2.9%. The fastest in the Asia Pacific region was 3.5%. The global demand for titanium dioxide...
This year, the tide of mergers and acquisitions in the high-tech industry in the United States was surging. In the first seven months, a total of US$100 billion in mergers and acquisitions was announced, setting a record high since 2000. Winners: Take-over by business owners: The forward-looking nature of Wall Street’s investment bank Silicon Valley reflects not only their innovation in technology and products, but also their increasingly close relationship with the financial industry (more...
A biodegradable plastic that uses nanotechnology to efficiently catalyze the synthesis of CO2 has been successfully developed by the Guangzhou Institute of Chemistry, Chinese Academy of Sciences. To make the project industrialized as soon as possible, Guangzhou Guangzhong Enterprise Group plans to invest 30 million yuan to participate in the construction of a new 3,000 tons/year degradable plastics production line. On June 5, the signing ceremony of the project industrialization test...
In order to further reduce the cost of polysilicon solar cells, the effect of the thickness of the silicon wafer on the short-circuit current density, open-circuit voltage and efficiency of the polysilicon solar cells was investigated. It can be seen that under the premise that the performance of the polycrystalline silicon solar cell is not changed or increased, the thickness of the silicon wafer can be reduced to 200 um. If the thickness continues to be reduced, the performance of the battery...
Making plastics from carbon dioxide is an innovative approach to reducing greenhouse gas emissions and creating sustainable materials. This process involves capturing carbon dioxide (CO2) emissions from industrial sources and using them as a raw material for the production of plastics. There are several methods to convert CO2 into plastics. One approach is to use a catalyst to convert CO2 into a chemical compound called ethylene carbonate. Ethylene carbonate can then be polymerized to form a...

Water-soluble silicon fertilizer 2 ~ 3 kg. With the increase of tree age, the application of fruit trees is different for each fruit tree. For example,...
Leaf spray water-soluble multi-effect silicon fertilizer better silicon method Research at home and abroad shows that nitrogen, phosphorus, magnesium, sulfur, and trace elements in the crop nutrients are the main components of the crop, increasing the application of the crop growth. However, as the dosage increases, crop resistance decreases, lodging is easy, pests and diseases increase, affecting quality yield. Potassium and calcium nutrients affect enzyme activity and composition and...
For silicon pu, you may hear such a word unfamiliar, but in fact, silicon pu is the most common product in our lives. For example, the playground of a school playground is full of silicone pu material, as is the basketball court. The walkways of the park are also everywhere. I believe that friends who often go to exercise their bodies will know that plastic on the court is in fact a silicon pu. So, do you know what silicon pu manufacturers have? Today I will come to recommend several good...
“With the high-tech polymerization of carbon dioxide, we can turn plastics with properties similar to those of polyethylene, and the plastic can be biodegradable. If we use this material to make disposable snack boxes, we will not only solve the environmental problems of carbon dioxide. It also solved the problem of white pollution.” A few days ago, Dr. Meng Yuezhong of the Guangzhou Institute of Chemistry of the Chinese Academy of Sciences held the first excellent “Returnees” forum held at the...
Professor Li Qingyun from the College of Horticulture, Hebei Agricultural University, said that due to the obstruction of gas exchange inside and outside the greenhouse during the production of celery, the concentration of carbon dioxide in the greenhouse decreased with the photosynthesis of celery, especially the concentration of carbon dioxide from 9 am to 1 pm low. In order to increase the photosynthesis rate of celery and promote the growth and development of celery, the application of...
1. Determine whether to apply silicon fertilizer based on the abundance of silicon in the soil. According to soil analysis tests to determine whether the local soil silicon content below the critical value, usually the effective silicon content in the soil in the range of 127 ~ 181 mg / kg is a lack of silicon soil. Application of silicon fertilizer has a significant increase in production. 2. Application method. (1) Suitable for basal fertilizer, not suitable for seed fertilizer. Can be...
