Background: Coal is one of the main energy sources in China and plays an irreplaceable role in social and economic development. Methane is the main component of gas explosion in the process of coal mining. This can be detected with a CH4 gas sensor. At present, the technology level of sensors used to detect methane […]

As a new manufacturing technology, 3D printing is developing rapidly in the industrial field. 3D printing often takes place in sealed rooms because many of the byproducts of the process can be harmful or toxic. In addition, any reaction between metals and the atmosphere, especially oxygen and nitrogen, must be minimized as much as possible. This is achieved

Overview: Hydrogen chloride is a toxic and harmful gas, and it will be highly corrosive when it encounters water. In order to reduce the harm of hydrogen chloride to the human body, many industries are now using hydrogen chloride detectors. Hydrogen chloride detectors can help us to detect the leakage of hydrogen chloride in time,

Smoking is harmful to health and can easily lead to lung diseases for a long time. Studies have found that most lung diseases are linked to smoking. Lung cancer kills millions of people every year and is the most common form of cancer in many countries, including China. Tobacco contains many harmful substances such as nicotine, carbon

Background： Nowadays, with the continuous increase of the refrigeration industry, ammonia gas alarms are also favored by the people. All links of agricultural and livestock products from harvesting, processing to commodity sales have been refrigerated. By slowing down the respiration and metabolism of fruits at low temperature, it can prevent decay. The purpose of prolonging

Background： With the rapid development of my country’s power industry and the implementation of institutional reforms. The current periodic maintenance system of power generation equipment has increasingly prominent drawbacks in the selection of maintenance tasks and the arrangement of maintenance cycles. The fuel for thermal power generation is mainly coal. During the operation of thermal

Overview： Everyone is familiar with carbon monoxide. Carbon monoxide poisoning incidents are among the past news incidents. Especially in the two seasons of summer and winter, news accidents are actually quite high. The reason why people are afraid of carbon monoxide is that carbon monoxide is colorless and odorless. It’s like an “invisible killer”, even

Background: In reIn recent years, environmental pollution has become more and more serious, bringing great harm. This also reminds us from another aspect to protect the environment and reduce the emission of pollutants. With the globalization of economy and trade, environmental pollution is also increasingly internationalized. The transboundary movement of hazardous wastes is a prominent

Background: With the continuous development of society, more and more cars are entering the homes of ordinary people. It brings convenience to people, and at the same time, car exhaust has also attracted people’s attention. In particular, the environmental harm caused by nitrogen oxides cannot be ignored. For the treatment of automobile exhaust gas, an

Background: In May 1968, Naoyoshi Taguchi, the founder of Figaro, was the first to invent the semiconductor gas sensor. Since then, it was not until the 1980s that my country began to develop gas sensors. Although it started late, it has achieved good results. With the development of my country’s electronic component technology and the
