Ammonia-resistant fluoroplastic composite soft material

Abstract

The invention discloses an ammonia-resistant fluoroplastic composite soft material. The ammonia-resistant fluoroplastic composite soft material comprises an electrical alkali-free glass fiber cloth. Fluoroplastic coatings are coated on two surfaces of the electrical alkali-free glass fiber cloth. The ammonia-resistant fluoroplastic composite soft material has good ammonia resistance and certain strength, can be used for a refrigerating fluid-resistant motor and is not damaged so that good slot insulation and phase insulation performances of the refrigerating fluid-resistant motor are guaranteed, and the refrigerating fluid-resistant motor adopting the ammonia-resistant fluoroplastic composite soft material satisfies slot insulation and phase insulation requirements in an ammonia refrigerating environment and works for a long time. Through the ammonia-resistant fluoroplastic composite soft material, the refrigerating fluid-resistant motor can be used in a closed refrigeration compressor system adopting ammonia as a refrigerating fluid.

Description

[0001] technical field [0002] The invention relates to an ammonia-fluoroplastic composite soft material. [0003] Background technique [0004] Scientific research has shown that Freon and other chemical substances used in the refrigeration industry are the main chemical substances that destroy the structure of the atmosphere and the ozone layer, and are also one of the important factors that cause global warming. At present, refrigeration systems generally use CFCs and HCFCs as refrigerants. The newly developed fluorine-free refrigerant system still uses fluorocarbons, which are still considered as an intermediate substitute for refrigerants. [0005] In order to reduce the damage of Freon to the ozone layer and the impact on the climate, countries have extensively carried out research on new refrigerants and new refrigeration systems, aiming to develop new refrigerants and refrigeration systems to reduce the emission of Freon. [0006] The hermetic refrigeration com...

Problems solved by technology

[0007] As a traditional refrigerant with excellent performance, ammonia has also been widely used in the refrigeration industry. However, due to the special physical and chemical properties of ammonia, The currently developed refrigerant-resistant motors cannot work in an environment filled with gas or liquid ammonia, so ammonia as a refrigerant cannot be used in fully enclosed refrigeration compressors that have been widely used at present

[0008]Refrigerant-resistant motors can work in an environment full of ammonia mainly because of the requirements for the slot insulation and phase insulation of the motor, which was also mentioned in our country a few years ago The subject has carried out research and proposed a scheme of using ammonia as a refrigerant. Aiming at how to use the existing refrigerant-resistant motor in the environment of ammonia, this scheme proposes a solution to add an isolation sleeve on the basis of the ordinary motor , but it has not been implemented due to major defects such as large volume and poor cooling conditions
