What types of environmentally friendly refrigerants are currently in use (classification)

The refrigerants widely used in compressed refrigerants are ammonia, Freon and hydrocarbons. According to their chemical composition, refrigerants can be divided into five categories: inorganic compound refrigerants, Freon, saturated hydrocarbon refrigerants, unsaturated hydrocarbon refrigerants and azeotropic mixture refrigerants.

Difference between car air conditioning refrigerant r134a and hfc-134a

As can be seen from the above, R134a and HFC134a are two different substances, but there is basically no difference in physical properties and they can be used interchangeably.

Automotive air-conditioning refrigerant market confusion and adulteration serious

On July 3, an investigation broadcasted by CCTV's Weekly Quality Report showed that the passing rate of auto refrigerants was less than 10%. According to the survey, only 5 out of 60 kinds of refrigerants purchased in Beijing, Hangzhou and Guangzhou auto parts markets were found to be qualified, with a passing rate of less than 10%.

What is polytrifluoroethylene and what are its main uses?

Vinyl trifluoride is prepared by homopolymerisation or copolymerisation of fluorine-containing monomers such as tetrafluoroethylene, hexafluoropropylene, vinyl trifluoride, vinylidene fluoride, vinyl fluoride, hexafluoroisobutylene, perfluoroalkyl vinyl ether and ethylene. The main types of fluoroplastics are listed below, but polytetrafluoroethylene is important in terms of quantity and use.

What are the differences between refrigerants and refrigerant carriers?

Many people confuse refrigerant and coolant. I will answer your question today. Refrigerant, also called refrigerant, is commonly known as snow in some areas of the south. It is a working substance that is constantly circulating in the refrigeration system, completing the cooling by changing its own state. The working substance that completes the thermal cycle in a refrigerator.

What are the properties of chlorotrifluoroethylene

The room temperature mechanical properties of chlorotrifluoroethylene are better than those of PTFE, with higher compressive strength, lower cold flow, higher compressive resilience and good elastic resilience. However, as chlorotrifluoroethylene is a crystalline polymer, its mechanical properties are strongly influenced by temperature and vary somewhat depending on crystallinity and molecular weight. When moulding, transparent products with low crystallinity can be formed by sudden cooling and translucent products with high crystallinity by slow cooling.

What is the production method of poly chlorotrifluoroethylene

Polychlorotrifluoroethylene was developed and produced as a thermoplastic fluoroplastic. the first report on its preparation was published by a French company in 1937 and later, in the course of the Manhattan Project, a great deal of research work was done in the USA on its preparation process route and product properties, which was put into production by 3M in 1942 and marketed under the Kel-F trademark.

What are the protective measures for chlorotrifluoroethylene

Chlorotrifluoroethylene can be mixed with air to form an explosive mixture and can cause combustion and explosion when exposed to open flame and high heat. At high temperatures, the internal pressure of the container increases and there is a risk of rupture and explosion.
