Polyurethane foam foam dimensional stability: cold storage polyurethane foam in severe temperature changes or at a relatively low temperature will appear dimensional changes (as contraction), the size changes often reflect bubble cracking or falling off, and these will inevitably affect the normal use of cold storage. In addition to regular simulation of performance testing, more emphasis is placed on the selection of high quality materials: special energy polyether compound use, so that the foam body mesh structure, greatly improving the foam low temperature resistance. At present, polyether commonly used in spraying materials contains a large number of functional components, and a large number of linear structures formed after reaction are difficult to be stable at low temperature; The use of the energy crosslinking agent also greatly improved the dimensional stability of the foam. The selected polyether adopts catalysis in the production stage, and the reaction is complete, so that the polyether maintains a high reaction rate (that is, it can react completely with black material); Some manufacturers in order to achieve foam appearance does not produce deformation phenomenon and add a hole component to foam material, reduce the bubble closed hole rate, achieve the effect of stable size, but it has sacrificed the thermal insulation performance of polyurethane cold storage insulation material foam.Floor insulation of small cold storage the structure of small cold storage is usually called surface, that is, the top, wall and ground are made of color steel plate / stainless steel with appropriate thickness of polyurethane and other insulation materials, because the loading and unloading of small cold storage is often handled manually rather than forklift. Of course, if the height of the warehouse is high and the forklift is required for warehousing, loading and unloading, the insulation board is not recommended for ground insulation, but the ground needs to be insulated separately like the ground insulation sample of medium-sized cold storage.Akoyapa,The general installation of air-conditioned storage will use air coolers for refrigeration. In this case, the temperature of such a controlled atmosphere reservoir may be too low. It is suggested that the unit can adjust the scale a little larger in the process of temperature setting.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 the structure of the cold storage plate shall be firm and have large bearing capacity. In low temperature environment, 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.Syracuse,The lights in the warehouse are not on. Please check whether the switch fails and whether the bulb is damaged. Cut off the power supply when installing the lampshade, and pay attention to the waterproof of the lamp.Where do you need to build the refrigerator, the size of the refrigerator or the storage capacity (size, storage capacity, ton, cubic meter, frame, you need to master your individual storage volume, the temperature of goods in and out of the warehouse, the frequency of opening and closing the door, etc. If this is clear,AkoyapaFreezer installation manufacturer, it is the selection of raw materials, such as refrigeration compressors, refrigeration units, industrial cooling fans / pipe slots, thermal insulation materials, coolers, doors, temperatures and other refrigeration equipment.Cold storage has good fire and flame resistance. After adding flame retardant, polyurethane is a kind of flame retardant and self extinguishing material. If it is burned by fire, it can be carbonized, unlike flow burning and flashover like extruded board, which can effectively prevent fire spread. In particular,AkoyapaDesign of fresh cold storage, it can be closed as a whole after fire prevention treatment to form non combustible products.

Cold storage has good water tightness. Polyurethane rigid foam has low water absorption, good permeability to water vapor, foam holes, disconnected and closed porosity of more than %. It is a dense microporous foam material, which is more dense than air surface, and is not easy to permeate. It belongs to hydrophobic materials.Generally speaking, the logistics cold storage project will be equipped with supporting electric cold storage doors and electric rolling shutter doors in the design of cold storage doors, rather than the traditional push-pull cold storage door configuration. Kende refrigeration said that this is because pushing and pulling the refrigerator door is not conducive to the locking of the refrigerator temperature, which is easy to cause serious loss of refrigeration capacity and is not suitable for logistics refrigerators that often go in and out.With the rapid development of modern commerce, the original cold storage for the purpose of product storage can no longer meet the rapid, accurate and small batch circulation needs of modern commodities. Therefore the logistics center cold storage cold chain for the purpose of product distribution came into being and developed rapidly, playing a more and more important role in the commodity circulation chain. What are the characteristics of the rapid development of cold storage construction?Trustworthy,Here we focus on polyurethane. Polyurethane is an ideal cold storage material in the cold storage project. Superior bonding properties make the foam and metal panels form a solid whole, so that no other adhesive materials are needed. When polyurethane is used as a cold storage project, rigid polyurethane foam is formed between the panels of the storehouse panel, and then solidified and pressed to form a multi shape storeboard, so that the overall rigidity is stronger and the bearing capacity is higher. Polyurethane filler board can meet the firmness and physical requirements of exterior wall and can be used in various cold storage projects. It is technically feasible and cost-effective. Yuanbao refrigeration believes that polyurethane is one of the new cold storage materials with great development prospects in the future. The thermal insulation materials of cold storage engineering should not only have good thermal insulation performance, but also be economical, namely stainless steel plate but also the types of cold storage. The common cold storage plates mainly include the following types we should not only inquire about the raw materials of the cold storage, color zinc steel plate, salted steel plate, embossed aluminum plate and mm galvanized standard floor plate.Polystyrene foam: polystyrene foam is a new type of synthetic thermal insulation material. It is a kind of plastic, with small density, light weight, due to its cold shrinkage, it is not very convenient for installation.After being stored in the medical cold storage project, 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.

Cold storage construction: which one is suitable for you? Which one is suitable for you?management, there are some unique installation skills when installing the cold storage? The cold storage installed according to these skills is often short in both effect and quality, and the specific installation skills of the cold storage will also make some relatively detailed introduction for you in the following article. When installing the cold storage, you should install it from the corner first. Later, according to the height of the cold storage, mainly to condense the refrigerant. The high-pressure temperature can reach Baidu and tighten the angle iron parts until there is a hole on the insulation boardThe high temperature and high pressure of the compressor of the wholesale condenser of the fresh-keeping warehouse as the heat sink and heat exchanger needs to be dissipated and heat exchanged through the condenser, and the temperature will drop to degrees after condensation.At ordinary times, users should check the sealing degree of the gap of the cold storage, and notify the cold storage for maintenance in time if damaged parts are found.Akoyapa,Polyurethane foam foam dimensional stability: cold storage polyurethane foam in severe temperature changes or at a relatively low temperature will appear dimensional changes (as contraction), the size changes often reflect bubble cracking or falling off, and these will inevitably affect the normal use of cold storage.
