Embodiment 1
[0041] A refrigerant replacing R-32, which is prepared by fully mixing the following raw materials in parts by weight: 12 parts of isobutane; 28 parts of octafluoropropane; 46 parts of difluoroethane; 14 parts of trifluoroiodomethane.
[0042] Its preparation method is as follows:
[0043] S1. Carry out rectification and purification of the three raw materials on the production line, and the rectification tower meets the height and standard of 99.96% of the refrigerant raw materials;
[0044] S2. The purity of the three raw materials is tested by an Agilent color analyzer to ensure that the purity reaches 99.96% of refrigerant grade;
[0045]S3. Connect the fully automatic and multi-functional microwave vacuum mixing tank. The model of the fully automatic and multi-functional microwave vacuum mixing tank is: YDL--6000L. The multifunctional microwave vacuum mixing tank has a fast heat reflux speed, can carry out normal pressure extraction, and shortens the production time by m...
