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, it can be closed as a whole after fire prevention treatment to form non combustible products.IztapalapaThe installation of top warehouse plate should be carried out alternately with the installation of wall plate, and the wall plate should leave a gap for withdrawing construction equipment; During the installation of the top warehouse plate, the end steel sheet at the overlap with the wall plate shall be disconnected for mm to prevent the cold bridge from running cold; Two layers of foaming materials shall be evenly and continuously punched on the joint surface between each top warehouse plate. Rivets shall be pulled and fixed at the internal and external lap joints of the steel plate, and the rivet spacing shall be mm; According to the design drawings, if there are supporting beams, columns and supporting steel frames in the warehouse, the setting out and positioning shall be carried out and accurate and clear marks shall be made according to the requirements of the design drawings; Weld or install the support beam, column,DenitrificationAssembled cold storage, support steel frame, and the welded junction shall be moisture-proof and treated according to the drawing requirements.The machine room of ammonia refrigeration system shall be equipped with exhaust assembly; The exhaust fan shall adopt anti motor. When the power supply is cut off due to unexpected refrigeration, it shall be able to ensure the reliable power supply of the exhaust fan. The overload protection of the exhaust fan should be applied to the signal alarm system without directly stopping the exhaust fan. The button box of the exhaust fan shall be concealed in the wall outside the ammonia compressor room.When installing polyurethane insulation board ensure that its surface is smooth and flat without scratch and warpage.

Cold storage is mainly used for frozen processing and storage of foodWhen adjusting the station, each outlet pipe shall be sawn into a degree inclined mouth to the bottom and the inlet pipe shall be points of the pipe diameter of the adjusting station.Thermal insulation performance of thermal insulation materials for food cold storage the requirement of polyurethane thermal insulation materials for cold storage is thermal insulation performance, and the quality of thermal insulation performance cannot be observed before it is really put into use. It is too late to observe the difference between power consumption. In this large number of experimental tests, strict material selection is carried out in order to achieve this goal: using structural amine ether to reduce thermal conductivity and improve thermal insulation effect; Reduce the water content of various raw materials and formulas as much as possible to avoid deterioration of thermal insulation performance caused by water foaming; Polyether: the product of a large processed factory after strict postprocessing is compared with the polyether of small factory without postprocessing. The foam cell has high uniformity of foam pores and thin wall of foam holes, and its heat preservation performance is obviously better than that of ordinary foam with thick wall and big hole. The use of the tasteless amine catalyst can effectively adjust the balance between foaming and gel reaction, so that the interlayer skin of the sprayed coating is thinner, which is beneficial to the performance of the thermal insulation material of the cold storage. Ordinary polyester polyols are not used.Inspection basis,Install the electric control system. The electric control system of the cold storage mainly includes electric controller, electric door, lighting and other electrical equipment in the cold storage. The power supply of the cold storage is required to be stable phase line, and the power supply or backup power supply can be used as required. The circuit shall have reasonable discharge and corresponding protective measures.The machine room of ammonia refrigeration system shall be equipped with exhaust assembly; The exhaust fan shall adopt anti motor. When the power supply is cut off due to unexpected refrigeration, it shall be able to ensure the reliable power supply of the exhaust fan. The overload protection of the exhaust fan should be applied to the signal alarm system without directly stopping the exhaust fan. The button box of the exhaust fan shall be concealed in the wall outside the ammonia compressor room.When using the cold storage, try to keep the ground clean and professional cold storage installation,DenitrificationProfessional installation of freezer,

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.Installation materials,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.With the rapid development of modern commerce, the original cold storage for the purpose of product storage can no longer meet the needs of rapid, playing a more and more important role in the commodity circulation chain. What are the characteristics of the rapid development of cold storage construction?Thermal insulation performance of thermal insulation materials for food cold storage the requirement of polyurethane thermal insulation materials for cold storage is thermal insulation performance, and the quality of thermal insulation performance cannot be observed before it is really put into use. It is too late to observe the difference between power consumption. In this large number of experimental tests,DenitrificationPrecautions for medical cold storage, strict material selection is carried out in order to achieve this goal: using structural amine ether to reduce thermal conductivity and improve thermal insulation effect; Reduce the water content of various raw materials and formulas as much as possible to avoid deterioration of thermal insulation performance caused by water foaming; Polyether: the product of a large processed factory after strict postprocessing is compared with the polyether of small factory without postprocessing. The foam cell has high uniformity of foam pores and thin wall of foam holes, so that the interlayer skin of the sprayed coating is thinner, which is beneficial to the performance of the thermal insulation material of the cold storage. Ordinary polyester polyols are not used.Denitrification, - precautions for floor installation of cold storage: the floor shall be installed flat, the uneven part shall be leveled with materials, and the locking hook between the plates shall be locked to ensure that the warehouse surface is flat without hollow feeling. (note that if this drainage system is installed outdoors in the north, the drainage pipe shall be insulated).For the ground insulation of large cold storage we can that the ground insulation of medium-sized cold storage is more complex than that of small cold storage, and the ground insulation operation of large cold storage with larger warehouse area will be more complex. The common operations are as follows: first lay the ventilation pipe to prevent the ground from freezing drum cracking, then lay the XPS extruded plate (staggered laying is required when laying the extruded plate), then lay the moisture-proof and vapor barrier on the upper and lower sides of the extruded plate, then pour the reinforced concrete (generally at least cm thick), and then make the emery floor or epoxy floor according to the requirements. Among them, the XPS extruded plate is also laid according to the warehouse temperature. For example, the XPS extruded plate with thickness of ~ mm needs to be laid in the general low-temperature cold storage, while the XPS extruded plate with thickness of ~ mm can be laid in the high-temperature cold storage.Cold storage construction: which one is suitable for you?
