Compared with the traditional polyurethane cold storage spraying, the cold storage board is more like a fixed product processed by the molding process. Cold storage board manufacturers said that unlike those liquid polyurethane compositions, cold storage boards are processed and pressed into rectangular boards one by one with molds, and then some hook grooves are left around to facilitate the interconnection of later boards.

In the past, many people worried about the hardness and quality of the board. In the past, civil engineering libraries were sprayed with a layer of paint on the basis of civil engineering. This cold storage is very popular in the past 20 years, not only durable, but also a long construction period.
Recently, in view of these questions that are often asked by cold storage board manufacturers, such as what are the advantages of cold storage board, what are the advantages compared to spraying. Mainly depends on your own choice, one is long time, the other is short time, the price of both sides is similar. It depends on the customer's own choice. What do you think?
Whether the choice of cold storage board is correct is very important for the construction of a high-quality cold storage. Therefore, the cold storage board manufacturers next to talk about the requirements of the cold storage board.
In the cold storage plate, the construction of medical cold storage has higher requirements for temperature, humidity and other environment. Therefore, when choosing a cold storage board, you should pay attention to the material and insulation strength of the board.
1. Wide, light and thin wall
Due to the use of polyurethane rigid foam as the structural material, the whole structure has the advantages of light weight, large span and large load. Thinner polyurethane sandwich panels can meet the relevant regulations of building energy consumption limits, allowing the use of thin panels during construction, saving building space.
2. Stable quality, long service life, high comprehensive cost performance
Cold storage board manufacturers said that under normal use and maintenance, the average life of rigid foam polyurethane insulation structure can reach more than 30 years. It can be guaranteed that during its service life, under normal use conditions, the structure will not be affected by external factors such as drying, humidity or electrochemical corrosion, as well as the growth of insects, fungi or algae or rodents.
3, moisture-proof, waterproof, good corrosion resistance
The closed-cell structure and surface material of the polyurethane rigid foam make it have better air resistance and water resistance, and it can be made into a mosaic connection structure during molding, which is convenient for later assembly. No additional insulation layer is needed to prevent moisture, which saves a lot of trouble in laying insulation layer.
4. Fire prevention, flame retardant and high temperature resistance
After adding flame retardants, polyurethane is a flame-retardant self-extinguishing material with a softening point of more than 250, and it will decompose only at higher temperatures. In addition, when burning, carbon deposits will be formed on the surface of the foam, which helps to isolate the foam below, can effectively prevent the spread of flame, and does not produce harmful gases at high temperatures.
