Description

Technical Field

[0001] This invention belongs to the field of cold storage technology, and particularly relates to a thermal insulation wall, a cold storage, and a method for manufacturing the same. Background Technology

[0002] Cold storage facilities are refrigerated using various equipment, and their operation is controlled to maintain a stable low temperature. They are widely used in the food, pharmaceutical, and chemical industries. A cold storage facility typically consists of several main parts, including the storage body, refrigeration system, cooling system, control system, and auxiliary systems. The storage body is the main structure of the cold storage facility, serving to maintain thermal insulation; its thermal insulation capacity is the primary factor in energy conservation.

[0003] Polyurethane is an ideal material for thermal insulation in cold storage facilities and is widely used in their construction. Rigid polyurethane foam has a thermal conductivity as low as 0.018~0.024 W / (m·K), making it one of the best choices for thermal insulation performance among common insulation materials. It effectively reduces cold loss and lowers energy consumption in cold storage. Its closed-cell rate is ≥90%, and this closed-cell structure prevents air convection, further reducing heat conduction, while also preventing moisture penetration that could degrade insulation performance. Polyurethane has good structural strength and durability, and its density typically ranges from 35~60 kg / m³. 3 With a compressive strength of 150~300kPa, it can withstand the loads of internal cold storage shelves, equipment, and transport vehicles. Within an extreme temperature range of -50℃ to +100℃, its volume change rate is extremely small, making it resistant to shrinkage or cracking over long-term use, with a service life exceeding 20 years. Rigid polyurethane foam can be directly bonded to cold storage walls, roofs, or interlayers via spraying, creating a seamless, integrated insulation layer and completely eliminating thermal bridging. It can also firmly bond with various substrates such as concrete, metal panels, and color steel plates, adapting to the complex structural requirements of cold storage facilities.

[0004] However, polyurethane itself is a flammable material. Pure rigid polyurethane foam is classified as a B2-class flammable material, meaning it will burn when exposed to an open flame, releasing heat and smoke during combustion. Rigid polyurethane foam can be modified by adding flame retardants to achieve a B1-class flame-retardant standard. These modified materials are not only less likely to be ignited by an open flame, but even if ignited, they can self-extinguish, further reducing the risk of combustion. However, this method is costly. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a thermal insulation wall, a cold storage facility, and a method for manufacturing the same, which achieves good thermal insulation effects, flame retardant properties, and low cost.

[0006] In view of this, the present invention provides a thermal insulation wall, comprising a wall body, a fireproof layer, and a thermal insulation fly ash layer filled between the wall body and the fireproof layer.

[0007] In this technical solution, by using inexpensive fly ash to fill the space between the wall body and the fireproof layer, a good thermal insulation effect can be achieved, which also has a flame-retardant effect and is low in cost.

[0008] Furthermore, the fireproof layer is a fireproof board, and an interlayer is formed between the wall body and the fireproof board to fill the aforementioned fly ash for insulation.

[0009] In this technical solution, both the wall body and the fireproof board are rigid, forming a sandwich layer between them that can accommodate fly ash, and the construction method is simple.

[0010] Furthermore, the thickness of the thermal insulation fly ash layer is between 50 mm and 1 cm.

[0011] Furthermore, the fly ash is either Grade I fly ash or Grade II fly ash.

[0012] Furthermore, the wall body adopts a brick-concrete structure.

[0013] Furthermore, the manufacturing method of the thermal insulation wall includes the following steps: S1: Create the wall structure; S2: The fireproof board is fixed parallel to and spaced apart from the wall body to form a sandwich between the wall body and the fireproof board; S3: Fill the interlayer with fly ash.

[0014] Furthermore, the wall itself is constructed using a masonry method.

[0015] Furthermore, the side of the fireproof board furthest from the wall itself is the interior.

[0016] Furthermore, a cold storage facility employs the aforementioned thermal insulation walls.

[0017] The beneficial effects of this invention are: 1. By using inexpensive fly ash to fill the space between the wall body and the fireproof layer, a good thermal insulation effect can be achieved, which also has a flame-retardant effect and is low in cost.

[0018] 2. Both the wall body and the fireproof board are rigid, forming a sandwich layer between them that can accommodate fly ash, making the construction method simple. Attached Figure Description
