Description

Technical Field

[0001] This utility model relates to the field of zinc plate technology, specifically to a zinc plate with cavity heat insulation effect. Background Technology

[0002] Zinc plate refers to steel plate with a layer of zinc on its surface. Zinc plating is a commonly used, economical and effective method of rust prevention, and about half of the world's zinc production is used for this process.

[0003] Traditional zinc sheets, such as galvanized steel sheets commonly used in construction, have poor thermal insulation properties. During the hot summer months, their surface temperature often rises above 60°C, significantly increasing the indoor heat load. Traditional insulation measures, such as adding a layer of rock wool, while effective to some extent, increase the overall thickness and weight of the material, making them inconvenient to use.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention, through the vacuum effect within the zinc plate body, can isolate heat transfer, and through the coating on the surface of the zinc plate body, can significantly reduce the surface temperature of the zinc plate. Furthermore, with the cooperation of the interlayer, the heat insulation effect of the zinc plate body is improved.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 As shown, a zinc plate with cavity heat insulation effect includes a zinc plate body 1, a number of honeycomb blocks 2 are fixed in the inner cavity of the zinc plate body 1, a number of ventilation grooves 3 are opened on the surface of the honeycomb blocks 2, the number of honeycomb blocks 2 are connected through the ventilation grooves 3, and an air extraction channel 5 is opened on one side of the surface of the zinc plate body 1, and a micro air extraction port 6 is provided on the surface of the air extraction channel 5.

[0020] Under the vacuum effect inside the zinc plate body 1, this utility model can isolate the transfer of heat. Under the effect of the coating on the surface of the zinc plate body 1, the surface temperature of the zinc plate is significantly reduced. In addition, with the cooperation of the partition layer 4, the heat insulation effect of the zinc plate body 1 is improved. Furthermore, under the effect of the honeycomb block 2, the structural strength of the zinc plate body 1 can be improved, preventing the zinc plate body 1 from collapsing due to the cavity during daily use.

[0021] A partition 4 is provided on the surface of the cavity of the zinc plate body 1. The material of the partition 4 is a zinc-nickel alloy coating. In this embodiment, through the setting of the partition 4, the zinc-nickel alloy coating is a metal coating that combines the properties of zinc and nickel. It is mainly used to improve the corrosion resistance, wear resistance and mechanical properties of the metal substrate, thereby improving the durability of the metal substrate of the zinc plate body 1.

[0022] Several honeycomb blocks 2 are continuously distributed in the inner cavity of the zinc plate body 1, and both ends are connected to the cavity of the zinc plate body 1. In this embodiment, this arrangement not only blocks the air convection heat transfer in the inner cavity of the zinc plate body 1, but also provides certain support for the use of the zinc plate body 1, avoids the zinc plate body 1 from being deformed by external force, and prevents the zinc plate body 1 from collapsing under vacuum negative pressure.

[0023] In vacuum technology, vacuum degree is a physical quantity that describes the rarefaction of gas within a vacuum container. Pressures below one atmosphere can be considered a vacuum. Numerically, vacuum degree is equal to the rarefaction pressure of the gas within the vacuum container, and its unit is Pascal (Pa).

[0024] The surface of the zinc plate body 1 is coated with a reflective heat-insulating coating with a reflective layer thickness of 5-10 μm. In this embodiment, through this coating, the reflective heat-insulating coating utilizes nanotechnology and special pigments to reflect most of the solar radiation energy, significantly reducing the surface temperature. The coating also has waterproof, crack-resistant, and corrosion-resistant properties, and is environmentally friendly and durable, suitable for metal surfaces, and can extend the service life of the zinc plate.

[0025] Ventilation slots 3 are equidistantly opened on the surface of the honeycomb block 2, and the aperture is ≤2mm. In this embodiment, this arrangement allows air convection in the inner cavity of each honeycomb block 2, and can achieve the effect of reducing airflow.

[0026] The diameter of the air extraction port of the air extraction channel 5 is 0.1-0.5cm. In this embodiment, this setting can avoid the loss of structural strength of the zinc plate body 1 and improve the practicality of the zinc plate body 1.

[0027] Working principle: After the zinc plate body 1 is installed, the operator can extract the air from the inner cavity of the zinc plate body 1 through the air extraction channel 5 and the micro air extraction port 6. Under the action of the air groove 3 on the surface of the honeycomb block 2, the air in the inner cavity of the zinc plate body 1 is connected, thereby improving the reliability of vacuuming. The vacuum degree is ≤10kPa. After the extraction is completed, low temperature glass powder is used to locally seal the area by infrared heating to prevent the zinc plate from deforming.

[0028] In daily use, the zinc plate body 1 can reflect and isolate heat under the action of the reflective heat insulation coating on the surface of the zinc plate body 1. Under the action of the vacuum in the inner cavity of the zinc plate body 1, heat can be isolated and transferred. Under the action of the honeycomb block 2, the structural strength of the zinc plate body 1 is improved, and the collapse of the zinc plate body 1 is avoided due to the vacuum being drawn.
