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, which helps to isolate the foam below. It can effectively prevent flame spread.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.Nanaimo,For those large-scale fresh-keeping warehouse wholesalers, if the equipment fails due to long-term neglect of maintenance the loss can not be ignored. Therefore, we should do a good job in the maintenance of fresh-keeping warehouse wholesalers in the process of daily use.The bacterial action of acid disinfectants is mainly to coagulate the protein in the bacteria. Common disinfectants include lactic acid, bleach, formalin, etc. Specifically, after the fish comes out of the freezer, clean the frost layer on the evaporating pipe group and keep the storehouse temperature below degrees Celsius. Then, the storeroom door is closed tightly with the sprayer, and the blower is started intermittently, so that the vinegar evaporates and flows in the storehouse,Generally speaking, the construction of cold storage is to ensure the quality of buildings with its strict heat insulation, sealing, firmness and frost resistance.Thermal insulation rigid polyurethane has low thermal conductivity and good thermal performance. When the density of rigid polyurethane is ~ kg / m, the thermal conductivity is only . ~ .w / (m.k), which is the lowest among all thermal insulation materials at present.The common phenomenon of quick freezing storehouse is that the temperature of quick freezing storehouse can't drop down or drops slowly. Now, a simple analysis is made on the reasons for the slow drop of temperature: the cold capacity loss of quick freezing storehouse is large due to poor thermal insulation or sealing performance; the poor thermal insulation performance is due to insufficient thickness of thermal insulation layer of pipeline and warehouse thermal insulation wall, resulting in poor thermal insulation and thermal insulation effect, It is mainly caused by improper selection of insulation layer thickness in design or poor quality of insulation materials in construction.

The door of the combined cold storage is not tightly closed. Please adjust the distance between the hinge on the door and the door lock and the storage body.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, as well as some after-sales training.Commissioning cold storage. After all parts of the cold storage are installed and connected, the cold storage can be started for cold storage commissioning. According to the needs of customers, adjust the value of the cold storage, the cold storage can reach the predetermined temperature, the cooling speed and the operation of the cold storage are normal, and the cold storage can be delivered for use. The cold storage installation unit shall also provide the cold storage user with training on cold storage use and management knowledge as well as some after-sales training.Recommendation and consultation,Whether the water pump works normally and whether the moldy switch is effective. In case of abnormality, timely handle the overhaul and maintenance of the refrigeration compressor in the cold storage: generally, the refrigeration oil and drying filter shall be replaced times after the operation of the cold storage equipment. Replacement after half a year. Depending on the circumstances.Cold storage design segmentation: several different partitions shall be reasonably planned and divided according to purpose and temperature. For example: processing room, sorting room, quick freezing room, refrigeration room,NanaimoHow to charge for the installation of cold storage, channel, unloading platform, etc.Wall and floor fixtures shall start at corners. According to the plate layout drawing, transport the two plates at the corner of the required device to the device location. According to the plate beam height and the model of the angle iron for fixing the mushroom head nylon bolt, drill a hole at the corresponding elevation in the middle of the plate width. When drilling, the electric drill should be perpendicular to the plate surface. Put the mushroom head nylon bolt in the hole, tighten the angle iron, and tighten it horizontally, so as to make the nylon bolt on the surface of the warehouse plate slightly concave. When setting up the wall panels, foam data and other soft data should be laid on the floor slots along with the floor of the storehouse,NanaimoPreservation of fruits in cold storage, so as to avoid damaging the storehouse. After the two corner panels are neutrally removed from the floor, the plane position of the wallboard and the verticality of the storehouse should be adjusted in time according to the location of the laying line, and check whether the top elevation of the wallboard can be correct. After the position of the wallboard is correct, weld the angle iron on the plate beam and fix the inner and outer corners. When welding the angle iron parts, the angle iron parts of the warehouse plate shall be covered with a shield to avoid the high temperature of the welding ground baking the warehouse plate and welding slag on the warehouse plate during electric arc welding.

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,NanaimoFood cold storage installation manufacturer, it can be carbonized, which can effectively prevent fire spread. In particular, it can be closed as a whole after fire prevention treatment to form non combustible products.Supply chain quality management,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.Protective fence shall be set around the door of the controlled atmosphere storage with eye-catching signs.For water-cooled units, the turbidity of cooling water shall be frequently, the cooling water shall be replaced frequently, and whether the running, dripping, leakage and other conditions of the water supply system exist.Nanaimo,The closed cell structure and surface material of polyurethane rigid foam with good moisture-proof, waterproof and corrosion resistance make it have better air resistance and water vapor resistance, and it can be made into inlaid connection structure during forming, which is easy to assemble. It does not need additional insulating layer to prevent moisture and saves a lot of trouble in laying insulating layer.Establish a perfect computer network, make the distribution of refrigeration supply chain scientific, and achieve the traceability of food safety. In the European Union the United States and Japan, descaling and air discharge in the refrigeration system of the warehouse.
