The original heat insulation method is to adopt the 'soil heat insulation' such as film, cotton quilt, etc. to wrap and cover, etc. to insulate heat, the heat insulation performance is poor, and the environment is polluted greatly, along with the progress of the technology, the appearance of the heat insulation materials such as glass fiber, asbestos, rock wool, silicate, etc. improves the heat insulation performance. In recent years, the application of novel heat insulation materials with lower heat conductivity coefficient, such as aerogel felts, vacuum plates and the like, greatly promotes the progress of heat insulation technology. The use of the heat insulation material greatly reduces the loss of heat energy in daily life and industrial production, improves the utilization efficiency of the heat energy and effectively reduces the energy loss.
The research and use of the vacuum insulation panel in developed countries abroad have been in history for more than ten years, the research and application of the vacuum insulation panel in China is relatively late, the vacuum insulation panel is mainly used in the fields of military industry, shipping insulation boxes, medical insulation boxes and the like in the early stage, and the vacuum insulation panel is widely applied to the fields of refrigerators, freezers, refrigerated vehicles, refrigeration houses, refrigerated containers, medical medicine boxes, buildings and the like in recent years along with the development of the domestic manufacturing industry, the issuance and implementation of national energy-saving policies, the reduction of core material cost and the enlargement of batch production scale, and meanwhile, the vacuum insulation panel is also applied to the fields of aerospace, food industry and the like.
Although the vacuum insulation panel has excellent heat insulation performance, due to factors such as the structural characteristics and the production process, the vacuum insulation panel has the following characteristics in the existing practical application:
(1) the vacuum heat insulation plate has a special structure, can not be cut and processed into various specifications and shapes in the application process, and can only determine the specifications and the sizes of products in advance according to the application conditions;
(2) the surface diaphragm of the vacuum heat insulation plate usually adopts a plurality of layers of polyester-based films, which are easy to scratch and damage, so that a protective device is usually required to be additionally arranged in practical application;
(3) after the membrane on the surface of the vacuum insulation panel is stressed and stretched, the membrane is easy to thin to generate air holes or damage a sealing edge, so the membrane cannot be bent or used on a curved surface with too small curvature radius in practical application;
(4) the edge of the vacuum insulation plate is not very flat because the sealing edge is usually not very flat, and a larger gap exists between the plate and the plate when the vacuum insulation plate is spliced, so the vacuum insulation plate is often used as a panel and is matched with a conventional heat insulation material such as rigid polyurethane foam to be used when being applied, and the splicing gap can be filled to prevent heat leakage;
(5) due to the limitation of production equipment, the area of the finished product of the domestic vacuum insulation panel is generally 2m at present2In the interior, when the connecting piece is applied to the condition of large wall surfaces such as a refrigeration house, a refrigerated container, a wall body and the like, the connecting piece is often needed for connectionBecomes a large plane.
Due to these characteristics of the vacuum insulation panel, most of its applications in various fields are small-area and small-volume applications, and the applied process method is to foam the vacuum insulation panel together with polyurethane foam into an integral block shape and then fill the block shape into various structures. The filling mode enables the filled structure to be layered with the integral block formed by the vacuum insulation panel and the polyurethane foam, so that the filled structure is difficult to bear large pressure, and the layered structure influences the heat insulation performance.
