Solar backboard with low water vapor permeability

The invention relates to a solar backboard with low water vapor permeability. The solar backboard comprises a polyester film, the surfaces at the two sides of the polyester film are each covered with a reflection reducing coating, one side, provided with the one reflection reducing coating, of the polyester film is connected with a weather-resistant layer through a high adhesive coating, the other side, provided with one reflection reducing coating, of the polyester film is also connected with a structure enhancement layer through a high adhesive coating, and the outer side of the structure enhancement layer is also bonded with a weather-resistant adhesive coating; and the high adhesive coatings are formed by copolymerizing maleic anhydride and hydroxyethyl methacrylate, and the polyester film is composed of a biaxially oriented polyethylene terephthalate film prepared by polyethylene glycol terephthalate. The material of the weather-resistant layer of the solar battery backboard is a fluorine-containing weather-resistant layer which has the advantages of low cost, good environmental protection performance and better mechanical performance and bonding strength than a conventional backboard. Through arrangement of the reflection reducing coatings on the surfaces of the polyester film, the transmittance of the film can be improved, and the insulation performance is also greatly improved. The water vapor permeability of the polyester film can reach 0.89g/m<2>, and the surface tension and the water resistance are quite high.

Mixed refrigerant replacing HCFC-22 as well as preparation method and application thereof

The invention provides a mixed refrigerant replacing HCFC-22 as well as a preparation method and application thereof. Under the working condition of high temperature, the mixed refrigerant is formed by 76-90% of fluoroethane, 1-11% of propylene and 1-23% of propane by mass percent. Under the working condition of medium temperature, the mixed refrigerant is formed by 1-92% of fluoroethane, 1-52% of propylene and 1-79% of propane by mass percent. During preparation, fluoroethane, propylene and propane are mixed uniformly in a liquid state in proportion. The mixed refrigerant has the advantages that the ODP (ozone depletion potential) is equal to 0; the GWP (global warming potential) is less than 12; the evaporation pressure, the condensation pressure, the pressure ratio and the standard boiling point of the mixed refrigerant are close to the evaporation pressure, the condensation pressure, the pressure ratio and the standard boiling point of HCFC-22; the temperature glide is less than 3K; the cycle performance coefficient, the unit mass refrigerating capacity, the unit volume refrigerating capacity and the standard volume refrigerating capacity of the mixed refrigerant are better than the cycle performance coefficient, the unit mass refrigerating capacity, the unit volume refrigerating capacity and the standard volume refrigerating capacity of HCFC-22; the unit mass power consumption and the exhaust temperature of the mixed refrigerant are lower than the unit mass power consumption and the exhaust temperature of HCFC-22; the mixed refrigerant can serve as a long-term substitute of HCFC-22 and can reduce the charge and energy consumption.
