Polyurethane foam: This is also a very common cold storage material. It has strong thermal insulation effect and strong mechanical strength. Now it is widely used and has a good application prospect. - Installation of the vertical plate of the cold storage: select the angle first according to the site conditions and locate it (i.e. lock the vertical plate and the floor) to extend to both sides at this angle. Only lock the vertical plate and the vertical plate, and locate it when it meets the vertical angle. Put the beautiful plate in a conspicuous place. When installing it on the side of the evaporator, make the drainage pipe in advance, and make U-bend and silica gel outside the storage.Twakan,With the continuous development of cold chain industry, the construction scale of logistics cold storage is expanding, and the construction quantity is also increasing. According to statistics, at present, the performance growth rate of cold chain is maintained at % ~ %; This leads to the increasing demand for logistics cold storage. In the design of logistics cold storage, people have strengthened the optimization and transformation of the existing cold storage on the basis of the design and construction of the new cold storage, so as to ensure its functions in product freezing, refrigeration, insurance and so on.Frozen and refrigerated storage began to change to shelf and pallet storage to complete the goods according to & ldquo; First in first out & rdquo; It is conducive to improve the quality of commodity storage and reduce loss.Bentong Town,The foaming technology of polyurethane with strong stability makes it have superior bonding performance. The firm combination of polyurethane rigid foam and carrier layer is the basic premise to ensure the stability of external insulation layer. That is, under the unfavorable local temperature and humidity conditions it can bear various internal and external combined loads such as wind force,TwakanHow much is it to install a small cold storage, self weight and normal collision, and the insulation layer still does not separate and fall off from the carrier layer and remains stable in the state.Operating the unit: regularly observe the oil level and oil return of the compressor and the cleanliness of the oil. If the oil is dirty or the oil level drops it shall be solved in time to avoid adverse effects.However, long-term continuous operation will inevitably lead to equipment aging, so reasonable maintenance is particularly important.

The foundation of cold storage is affected by low temperature, and the water in the soil is easy to be frozen. Due to the volume of frozen soil, the ground will be broken and the whole building structure will be deformed. If the damage is serious, it may even make the cold storage unusable. Therefore, in addition to the thermal insulation layer, the floor of low-temperature cold storage must be treated under the thermal insulation layer to prevent soil freezing. The bottom plate of the cold storage shall stack a large number of goods and pass through various loading, unloading and transportation machinery and equipment. Therefore, especially in the process of periodic freezing and thawing cycle, building structures are vulnerable to. Therefore, the structure of each part of the cold storage and the building materials of the cold storage should have sufficient frost resistance.After years of service, the refrigeration oil inside the compressor should be replaced. The oil, copper, iron and impurities caused by wear are mixed in the refrigeration system, which thickens the refrigeration oil, deteriorates the fluidity and performance, reduces the effect, takes a long time, increases the burden on the compressor, and the current will increase relatively compared with the new machine, which is a bad phenomenon.Install the library body. Generally, the warehouse body can be divided into small warehouse body and large warehouse body. The small warehouse body is basically a combined cold storage assembled with warehouse plate. The large warehouse body is mostly a civil cold storage. The assembled or constructed warehouse body is generally required to be flat,TwakanCold storage installation and construction company, compact and solid, without hollow feeling, load-bearing antifreeze, moisture-proof, etc.Where can I find it?,According to the size and nature of the cold storage area and in combination with local regulations, and the structure is the selection of steel structure or reinforcement solidification. Cold storage capacity whether it is a single-layer or double-layer warehouse, production process, refrigeration, product stacking, temperature, etc. are used to determine the size and location of the cold storage room, so that it can become a whole.Watertight polyurethane rigid foam has low water absorption,TwakanInstallation of small cold storage, good permeability to water vapor, which is more dense than the surface of the air, and is not easy to permeate. It is an hydrophobic material. - floor installation of cold storage: first level the floor, then install the floor, select a beautiful floor and put it in a conspicuous place, and do a good job in the floor and evaporator drainage system.

Some cold bridge prevention measures shall be taken at the joints between polyurethane insulation boards.average method,Operating the unit: regularly observe the oil level and oil return of the compressor and the cleanliness of the oil. If the oil is dirty or the oil level drops, it shall be solved in time to avoid adverse effects.Selection of cold storage thermal insulation materials the use of cold storage thermal insulation materials is adapted to the times. It is specialized in cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage, old brand, but also has high cost performance.Fault phenomenon: high current or tripping during unit startup, and problems of user air switch; Input voltage is too low; The star angle conversion interval is too short (it should be ~ seconds); Hydraulic cylinder failure (no reset); Intake valve failure (too large opening or stuck); Loose wiring; Host failure; Main motor fault; TR time relay is broken (relay unit).Twakan,There are two kinds of refrigeration in the cold storage group: immediate refrigeration and simple refrigeration.Cold storage is mainly used for frozen processing and storage of foodPolyurethane with good fire resistance and flame retardancy is a kind of refractory and self extinguishing material after adding flame retardant. In case of fire, it can be carbonized, unlike flow burning and flashover like extruded board, which can effectively prevent fire spread. In particular, it can be sealed as a whole after systematic fire prevention treatment to form non combustible products.
