Advantages and disadvantages of carbon dioxide

The main advantage of carbon dioxide is that it is an essential raw material for plant photosynthesis, and its content increases, which is beneficial to plant growth. Carbon dioxide can be used as chemical fertilizer for greenhouse vegetable cultivation to increase crop yield. Carbon dioxide can be used as an oxygen source in diving and aviation. It is also used for fire extinguishers.

Liquid carbon dioxide has a broad application prospect. Using liquid carbon dioxide as the medium for extracting natural compounds from some plants or plant sources will not only destroy the bioactive substances contained in the raw materials, but also contain no residual medium in the products. By spraying liquid carbon dioxide to demist the airport, the demisting efficiency is hundreds of times higher than that of solid carbon dioxide.

Using carbon dioxide instead of traditional organic solvent for painting can effectively reduce the amount of harmful substances released into the atmosphere during painting. ?

Main hazards:

The main harm of carbon dioxide is the greenhouse effect. The greenhouse effect caused by the increase of carbon dioxide melts polar glaciers, leads to the rise of sea level, endangers coastal cities, salinizes coastal land and increases the difficulty of development. The rising temperature has also caused the snow on some hilltops to melt, and the water volume of rivers with snowmelt as water resources has decreased or even stopped, which has affected the production activities in these areas. ?

The increase of atmospheric temperature causes a large number of algae plants that absorb carbon dioxide in the ocean to multiply, leading to the death of phytoplankton that absorb carbon dioxide, indirectly affecting the reproduction of fisheries, and making the increase of carbon dioxide in the atmosphere enter a vicious circle.

Extended data:

Liquid carbon dioxide fire extinguisher is to put liquid carbon dioxide into a small steel cylinder under pressure. This kind of fire extinguisher can be used to put out fires such as books and documents, expensive equipment and precision instruments. Foam extinguisher can spray a lot of carbon dioxide and foam. These foams are tightly attached to the combustion products, which can isolate the combustion products from the air and achieve the purpose of fire fighting. Foam extinguisher can be used to put out fires caused by common substances, such as paper, cotton cloth, wood and plastic.

The application and development of carbon dioxide are becoming more and more mature. Global suppliers of components and systems, including Danfoss, Calais, Blaco, Louvre, Emerson and GMCC gmcc, have followed this trend and provided carbon dioxide solutions for the commercial sector.
