Problems solved by technology

As a result, the suction temperature is too high, reducing the cooling capacity of the compressor, which in turn affects the cooling efficiency of the compressor, which is not conducive to the further improvement of product performance
[0004] Therefore, the research on improving the working efficiency of the compressor still needs to be deepened.

Embodiment 1

[0035] The hollow microspheres (selected from Al 2 o 3 , ZrO 2 , SiO 2 At least one of the above) is mixed with fluorosilicon-modified acrylic emulsion, and evenly stirred by a mechanical stirrer to obtain a heat-insulating coating in which the hollow microspheres are 85% by weight, wherein the average size of the hollow microspheres is 40 μm. Inject the obtained thermal insulation coating into the spraying system, and evenly coat the outer surface of the suction pipe by spraying to form a layer of porous sealing coating that takes into account both thermal insulation and toughness. The film thickness is 0.1mm, and the obtained The suction pipe is assembled to the compressor and the cooling capacity test is carried out. The results show that at 80 °C, the inner wall of the copper tube can be reduced by 6 °C, and the cooling capacity can be increased by 1.7%, which effectively improves the cooling efficiency.

Embodiment 2

[0037] The hollow microspheres (selected from Al 2 o 3 , ZrO 2 , SiO 2 At least one of the above) is mixed with fluorosilicon-modified acrylic emulsion, and stirred evenly by a mechanical stirrer to obtain a heat-insulating coating in which the hollow microspheres are 50% by weight, wherein the average size of the hollow microspheres is 20 μm. Inject the obtained thermal insulation coating into the spraying system, and evenly coat the inner surface of the suction pipe by spraying to form a layer of porous sealing coating that takes into account both thermal insulation and toughness. The film thickness is 0.5mm, and the obtained The suction pipe was assembled on the compressor and carried out the cooling capacity test, obtained the result similar to that of Example 1.

Embodiment 3

[0039] The hollow microspheres (selected from Al 2 o 3 , ZrO 2 , SiO 2 At least one of the above) is mixed with fluorosilicon-modified acrylic emulsion, and evenly stirred by a mechanical stirrer to obtain a heat-insulating coating in which the hollow microspheres are 90% by weight, wherein the average size of the hollow microspheres is 80 μm. Inject the obtained thermal insulation coating into the spraying system, and evenly coat the outer surface of the suction pipe by spraying to form a layer of porous airtight coating that takes into account both thermal insulation and toughness. The film thickness is 1 mm, and the obtained The suction pipe was assembled on the compressor and subjected to a cooling capacity test, and the results similar to those in Example 1 were obtained.

Description

technical field [0001] The present invention relates to the field of material technology, in particular, to thermal insulation coatings and applications thereof, more specifically, to thermal insulation coatings, thermal insulation coatings formed from the thermal insulation coatings, workpieces containing the thermal insulation coatings, and Compressor for the workpiece. Background technique [0002] For energy-saving reasons, how to improve the working efficiency of the compressor has always been the direction of technical improvement. The airtight casing of the compressor is provided with a suction pipe interface and an exhaust pipe interface. There is a conical suction pipe between the suction port of the cylinder and the suction interface. When the compressor is working, the low-temperature gas is sucked into the cylinder from the conical suction pipe, and after being compressed, it becomes high-temperature and high-pressure refrigerant from the exhaust tube discharge...
