When installing the polyurethane insulation board, the adhesion between the panel of the polyurethane insulation board and the thermal insulation material is short and often high.The importance of regular oil discharge, descaling and air discharge in the refrigeration system of the warehouse.San Pedro sacartepex,After the installation of the controlled atmosphere storage, another important finishing work is to purge the whole system. Compressed air will clean out the impurities remaining in the controlled atmosphere storage, which plays a key role in the use of the controlled atmosphere storage.Acid disinfectant can be used for mold removal and disinfection of quick-frozen warehouse.Berber,Improper adjustment or blockage of throttle valve too large or too small refrigerant flow: improper adjustment or blockage of throttle valve will directly affect the refrigerant flow into evaporator. When the throttle valve is opened too large, the refrigerant flow is too large, the evaporation pressure and evaporation temperature also increase, and the decline rate of warehouse temperature will slow down; At the same time, when the throttle valve is opened too small or blocked, the refrigerant flow will also decrease, the refrigeration capacity of the system will also decrease, and the decline rate of warehouse temperature will also slow down.The new cold storage material is made of rigid polyurethane or polystyrene foam insulation sandwich panel which is made by high pressure foaming process and can be made into various lengths and specifications to meet the different requirements of the users.The type of cold storage to be built in the type of cold storage should be determined according to the type of circulating goods. For example, the cold storage that only circulates vegetables can only build a fresh-keeping cold storage, while the cold storage with refrigeration + freezing will be built if there are many types of circulating goods and great difference in storage temperature. As for the size of the cold storage, it should be determined according to the type, quantity, frequency, cycle, whether to use shelf stacking and so on. For example, for fruits and vegetables packed in cartons, the storage capacity of -kg per cubic meter can be referred to, and the size of cold storage construction can be estimated in combination with the storage capacity rate of about .-..

The physical properties of polyurethane insulation board are relatively good, which can meet different needs. The polyurethane insulation board is also strict in the selection of materials. It is a special product manufacturing enterprise integrating R & D, and service. It has long been specialized in cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage and medical cold storage. It improves the overall performance of the polyurethane insulation board and enables the polyurethane insulation board to work for a long time, Polyurethane insulation board has also become one of the main exterior wall materials.All lifting bolts of the cooling fan shall be fastened. Professional cold storage installation, installation of cold storage, cold storage construction, fruit preservation cold storage, medical cold storage, high price, service, on-site settlement, honest management! The holes of bolts and lifting bolts shall be sealed with sealant to prevent cold bridge and air leakage.The combined cold storage door starts frequently or does not start for a long time,San Pedro sacartepexInstallation of professional cold storage, or does not stop for a long time, or stops before the storage temperature reaches.install,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.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, because the metal plate can roll out different waveforms, 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, applicable and environmental friendly. To ensure the smooth progress of our cold storage project, we should not only inquire about the raw materials of the cold storage, namely stainless steel plate, color zinc steel plate salted steel plate, embossed aluminum plate and mm galvanized standard floor plate.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.

Cold storage construction: which one is suitable for you? Which one is suitable for you?Inspection items,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.Whether it is a fruit fresh-keeping warehouse or other cold storage, there are many details to pay attention to in the transformation of the cold storage. If other small items are not done well, such as high energy consumption and small problems.As a coolant make it evaporate under low pressure and mechanical conditions to absorb the heat in the storage, so as to achieve the purpose of cooling.San Pedro sacartepex,The polyurethane insulation board shall be connected by plug-in notch connection, because it has higher strength when connecting in this way.According to the size and nature of the cold storage area and in combination with local regulations, the construction form of food cold storage warehouse is to determine the plane layout based on the site, production process,San Pedro sacartepexInstallation of aluminum bar in cold storage, 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.Airtight construction of quick freezing storehouse: the modified atmosphere fresh-keeping storehouse is developed on the basis of the traditional high-temperature fresh-keeping storehouse, which has the & ldquo; Refrigeration & rdquo; Function, long-term cold storage installation, cold storage installation, cold storage construction, fruit fresh-keeping cold storage,San Pedro sacartepexHow to install the cold storage unit, medical cold storage, excellent quality and favorable price. There are also & ldquo; Air conditioning & rdquo; Function; However, the quick freezing storehouse is not a simple superposition of ordinary high temperature storehouse and air conditioning equipment. In order to adjust the gas composition in the storehouse quickly, it is necessary to ensure that the quick freezing storehouse has good air tightness. This has been confirmed by the theoretical research and a large number of practical experience of quick freezing warehouse.
