The importance of selecting good polyurethane cold storage / cold room panels:
Question: Why is it important to choose a good polyurethane cold storage panel?
Answer: Because the good or bad of polyurethane cold storage panel is related to the temperature and time of cold storage refrigeration.
The good choice of polyurethane foam sandwich panel is very important for cold storage, because the cold storage is different from ordinary warehouses, and the temperature in the cold storage is generally low, and the temperature, humidity, and environmental requirements of the air are relatively low, and the requirements of the air, humidity, and environmental requirements are compared High, so when choosing a polyurethane cold storage board, we must pay attention to choose a polyurethane cold storage / cold room panels with good thermal insulation effect. If the polyurethane cold storage board is not selected, it is difficult to control the temperature in the cold storage, which will easily cause it in the cold storage in the cold storage store. The product is deteriorated, or the cold storage refrigeration compressor work frequently, waste more resources and increase costs.
Choose a high -quality cold storage PU sandwich panel to better maintain the cold storage. The panel materials used for the cold storage warehouse are currently used with polystyrene foam EPS materials and hard polyurethane foam as the core material and metal as the surface material. PU have very good thermal insulation and thermal insulation performance. Having flame retardant is also a feature of people who choose it to make cold storage insulation materials. Polyurethane foam is currently used in many fields. The flame retardant of polyurethane foam at home and abroad is paying more and more attention. The application fields in the industry, furniture, and construction industry have strict flame retardant requirements for their architectural materials. The flame retardant effect of polystyrene EPS is far lower than polyurethane foam, and a large amount of harmful gases will be generated when the polystyrene EPS is burned.
What are the influencing factors of polyurethane cold storage / cold room insulation panels?
①The fire level of the core material.
The polyurethane cold room insulation panels is divided into three levels: B1, B2, and B3. The amount of black material depends on the key factor of the fire level of polyurethane cold storage board. The more black materials, the higher the fire level of cold storage polyurethane foam sandwich panel; otherwise, the lower the fire level of polyurethane cold storage board. Different fire prevention levels are also different. The higher the fire prevention level, the higher the price.
②Upper and lower steel plate.
The polyurethane cold storage panel has two layers of upper and lower steel plates, and the price of upper and lower steel plates is affected by factors such as thickness, manufacturers, galvanized content and other factors. The higher the upper and lower steel plate requirements, the higher the price will be higher.
③The specifications of polyurethane cold storage panels.
The effective width of cold storage PU sandwich panel is 920-1120mm, and the thickness is 50-250mm. The specifications are different and the price is different.
What are the differences in the three fire -resistant levels of polyurethane cold storage panels?
The core materials of cold storage polyurethane foam sandwich panel are basically foamed with black white, catalysts, and foaming agents, and the difference in the fire level of polyurethane cold storage board depends on the amount of black and white materials. The white material of polyurethane cold storage plates is divided into three levels: B1, B2, and B3. Which level of polyurethane cold room panels needs to be produced directly. , But the amount of black material depends on the fire level of polyurethane cold storage board. The more black materials, the higher the fire level of polyurethane cold room insulation panels ; otherwise, the lower the fire level of polyurethane cold storage board.
Introduction to quick-freezer cold storage :
The quick-freezing device is mainly used for the processing of fast-freezing products, so that food can quickly pass through the large ice crystal production area in the freezing process, reduce the loss of water and juice in food, and can effectively inhibit the role of microorganisms and enzymes inside the food, and maximize the maintenance of the original nutritional value and color and flavor of the food. At present, the quick-freezing device is widely used in meat, poultry, aquatic products, conditioned food, vegetables, ice cream, dairy products, blood products and other industries and varieties of rapid freezing processing, quick-freezing equipment mainly includes: tunnel series freezing device, spiral series freezing device, fluidized freezing device, liquid nitrogen spray freezing device, etc.
The temperature of the quick-freezer is generally -20 °C ~ -25 °C, -20 °C ~ -35 °C and -25 °C ~ -45 °C Several. The temperature of the special cold storage can reach -60 °C or less, and a library can be realized with double temperature or multiple temperatures to meet the needs of different users.
What are the characteristics of the frozen /quick-freezer cold storage?
The cold storage adopts advanced microcomputer control system, and the liquid crystal displays the temperature, boot time, defrosting time, fan delay time, alarm indication and various technical parameters in the cold room. The operation is simple and very convenient for users to use.
The main components of the cold storage are selected from international well-known brands, which ensure that the configuration of the cold storage is reasonable, the operation is stable, the thermal insulation performance is good, the low consumption and high energy are high, and the quality is excellent. The panels of the quick-frozen warehouse are divided into four types: FRP plate, color steel plate, embossed aluminum plate and stainless-steel plate. It is possible to reduce the heat transfer due to the temperature difference between the inside and outside of the warehouse to achieve the maximum efficiency of the refrigeration and refrigeration system. The insulation board is made of hard polyurethane infusion or polystyrene composite insulation board, which has the advantages of light weight, high strength, corrosion resistance, anti-aging and good thermal insulation.
