Zhejiang Yuyao City's new materials research and development production field has been proliferating. The “An annual output of 250 tons of electronic ultra-low oxygen ultra-high-purity titanium project†independently designed and constructed by Ningbo Chuangrun New Material Co., Ltd. in Linshan Town, Yuyao was officially put into production the day before yesterday. The output of China's first furnace ultra-high-purity titanium not only filled the gap. The gap between China's related industries and technologies has also broken the monopoly of developed countries on this project. As a strategic high-end metal material, titanium metal has the characteristics of light weight, high strength and corrosion resistance. It has always been a strategic key material for aircraft manufacturing and aerospace industry, and it is crucial for national security and national defense construction. Important role. As the world's largest producer of titanium metal in the world, China has the largest production capacity of titanium sponge. In 2013, the output was about 120,000 tons. The production capacity was seriously over-supplied, and the market price was 47,000 yuan per ton. At the same time, it was completely blank in the field of high-purity titanium. The low-oxygen ultra-high-purity titanium has a higher added value, and the market price is as high as 1 million yuan per ton. At present, only three companies in the United States and Japan can produce ultra-high-purity titanium. As a high-end metal material, the United States strictly limits its exports to China.
“The annual production of 250 tons of electronic ultra-low oxygen ultra-high-purity titanium project†is led by Dr. Wu Jinghui, one of the Chinese experts in the “Thousand Talents Program†and one of the few Chinese experts in the field of metal and titanium purification. The project purifies the titanium sponge with a purity of 99.8% to 99.999% titanium crystal by molten salt electrolysis process, and then casts the crystal into high-purity titanium material through vacuum electron beam melting equipment, the process line and related equipment involved. Designed by the entrepreneurial team and possessing complete intellectual property rights, it has applied for 11 national invention patents. In 2013, the National Development and Reform Commission and the Ministry of Industry and Information Technology listed the project in the national key industry revitalization special fund support project, with a total investment of 200 million yuan, and realized a sales income of 400 million yuan after reaching production. Dr. Wu Jinghui introduced that the project has low energy consumption, non-toxic emissions, high added value of products, and advanced technology. The products produced are directly supplied by Ningbo Jiangfeng Electronic Materials Co., Ltd. to produce ultra-high purity metal sputtering targets. At the same time, the company has reached an agreement with the "AviChina Science and Technology Third Institute" and other institutions to establish a long-term stable strategic partnership, which will play an important role in promoting the transformation and upgrading of China's military, aerospace, medical equipment and other high-end enterprises.
The pH sensor is an important part of the PH ORP Analyzer. The analog pH sensor usually does not have any signal output, and a transmitter is required to convert the chemical signal into an electrical signal. Daruifuno's pH electrodes are online composite electrodes, which are composite electrodes combined with a glass indicator electrode and a reference electrode. The measurement principle of pH is based on the potential difference measured in the solution by the working battery composed of the measuring electrode and the reference electrode, and the online monitoring of pH is realized by using the linear relationship between the pH value of the solution to be measured and the potential of the working battery .
Daruifuno's analog pH sensor come in a variety of styles, including ASP120 series glass electrodes, which are suitable for various special industrial environments. They are often resistant to high temperatures and strong acids and alkalis, and are used in fermentation, pure water, and chemical industries. There are also pH probes packaged in plastic cases used in surface water monitoring, sewage plants, water plants, aquaculture and other industries. Of course, we also have low-cost pH electrodes for use in laboratories or agricultural irrigation and hydroponic industries.
Our pH electrodes have built-in temperature cells, fast response, large reference and long life.
