Fire retardant, flame retardant and high temperature resistant polyurethane is a kind of flame retardant self extinguishing material after adding flame retardant. Its softening point can reach more than ℃, and it will decompose only at higher temperature. In addition, polyurethane forms carbon deposits on the surface of the foam,OstrovHow much is the installation and construction cost of cold storage, which helps to isolate the foam below. It can effectively prevent flame spread.Install the temporary lighting facilities in the warehouse, install and arrange the construction electrical equipment, and do a good job in rain proof, moisture-proof, anti-collision, anti binding and other safety protection.Ostrov,Because long-term wind and sun exposure is easy to cause line aging, short circuit, leakage and other accidents; After the fresh-keeping storehouse is installed and connected, it is necessary to start and debug the fresh-keeping storehouse, and adjust the value of the fresh-keeping storehouse to the appropriate temperature; The installation unit of fresh-keeping storehouse needs to provide the user of fresh-keeping storehouse with knowledge training on how to use and manage the fresh-keeping storehouse, ventilating medical products may also emit some odors. Once these odors are stored in a certain quantity, they will also have a certain impact on other products. Therefore, we must carry out regular ventilation in the process of daily use, so as to effectively reduce the storage time of products. If the medical cold storage project uses row tube refrigeration, the image of frosting may appear after use for a period of time. If we do not defrost in time, it will also affect the effect of. Therefore, I hope you must pay attention to defrosting.White,Step of cold storage design: define the volume of the cold storage warehouse. The size of the cold storage should be based on the design of a large number of agricultural products to be stored for a long time. This volume is calculated based on the essential volume of stored goods accumulated in the cold storage, plus the row to row corridors, the indoor space between the pile and the wall, the ceiling and the gap of the packaging house. After the volume of the cold storage is determined, the length and height width ratio of the cold storage shall be determined. Necessary auxiliary engineering buildings and equipment shall also be considered in the design of cold storage, such as working intermediate, packaging and combing room, special tool warehouse, loading and unloading platform, etc.The spacing of pull rivets at inner and outer corners is mm and mm respectively; After the polystyrene library is installed, the wall panel joints shall be evenly sealed and decorated with silicone sealant.Strong deformation resistance, not easy to crack, smooth, stable and safe. Polyurethane material has stable porosity structure and basically closed pore structure. It not only has excellent thermal insulation performance, but also has good freeze-thaw resistance and sound absorption performance. Under normal service and maintenance conditions, the life expectancy of rigid foam polyurethane insulation can reach more than years. During the structural life period, it can reach the unit price of dry, wet or electric corrosion under normal service conditions, while the unit price of insect, fungus or algae foam material is higher than other traditional insulation materials, but heating will increase the cost and the cooling cost will be greatly reduced.

Cold storage board, compressor, and other components in the cold storage can reasonably adjust the evaporation and condensation temperature, so as to improve the reduction of power consumption and reduce the production cost. Professional cold storage installation, installation of cold storage, cold storage construction, fruit preservation cold storage, medical cold storage, quality assurance, professional timely supply and high cost performance. It has become the preferred brand for many wire products. Welcome to buy! Save more resources.Disadvantages: high precision requirements, shape and position tolerances are in micron level; No exhaust valve poor off design performance; The working chamber is not easy to implement external cooling, and the heat in the compression process is difficult, so it can only compress the gas with small adiabatic index or internal cooling; Large displacement scroll refrigeration unit is difficult to realize. The receiving teeth are high, the displacement is large, the diameter is large, and the unbalanced rotation mass increases.Install the temporary lighting facilities in the warehouse, install and arrange the construction electrical equipment, and do a good job in rain proof, moisture-proof, anti-collision, anti binding and other safety protection.Price, and the heat transfer effect decreases: another important reason is that the heat transfer efficiency of evaporator is low, which is mainly caused by excessive frost or excessive dust on the evaporator surface.All wiring shall be neat. All switches and keys shall be opened and closed sensitively, reliably and accurately. Special connectors shall be used for wiring, and power protection shall be provided for the box and each power branch.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).

Floor insulation of medium-sized cold storage the structure of medium-sized cold storage is what we often call the surface, that is, the top and wall are made of color steel plate / stainless steel with appropriate thickness of polyurethane and other insulation materials, while the ground needs to be insulated separately. At present, the common operations in the market are: laying the ground with XPS extruded board, laying moisture-proof and steam isolating SPS materials above and below the extruded board respectively, and then pouring concrete or reinforced concrete.Product survey,The use of large-scale cold storage is naturally very strict in installation and material selection. Therefore, in the face of the above possible situations, we can strictly screen the insulation board materials of cold storage which can effectively alleviate or solve the above problems. However, at present, there are many fields using cold storage insulation board, so the details of the use environment should be considered for the wood making of many such products in the market.Due to the slow cooling, the equipment will stop and cannot consume electricity, so the electricity charge will not be consumed. As a high energy consuming equipment, the daily power consumption of cold storage is relatively large. If the refrigeration effect is not good, the annual use cost will directly double several times. Moreover, the service life will be reduced accordingly, which is something users don't want to see.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.Ostrov,We must often use insulation board in our life. It's just the structure of the refrigerator, but the refrigerator, as a in the home, the environment of cold storage insulation board is not so optimistic. Professional cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage quality assurance. During the preferential activities new and old customers are welcome to consult. The environmental differences inside and outside the cold storage insulation board are very large,OstrovFresh storage cold storage,OstrovMedical cold storage, because a large number of items need to be insulated, so the temperature in the cold storage is strict. In such cases, and the penetration of the envelope is carried out from outside to inside all year round. R gas in polyurethane is replaced by air and water vapor to damp polyurethane. Over time Let's understand that the water vapor pressure outside the plate warehouse of the lower cold storage is higher than that inside the warehouse, moisture becomes more and more serious and even water vapor condensation occurs, resulting in low thermal conductivity and reduced thermal resistance. In order to avoid and delay polyurethane moisture and prolong the service life of the insulation layer, it is effective to seal the hot side of the insulation layer, that is, to form a vapor barrier layer.In order to prevent damage to the cold storage, it is necessary to lay some foam on the floor of the cold storage tank.General quick-frozen warehouses are mostly cooled by refrigeration mechanism with low gasification temperature (ammonia or Freon)
