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), 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, 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.The refrigeration of cold storage pays more and more attention to the needs of environmental protection and energy saving. Professional projects include: cold storage installation, installation of cold storage, cold storage construction, fruit fresh-keeping cold storage, medical cold storage and other related businesses. Merchants who hope to have this business please consider the wide scale of warehouse temperature control, the selection and placement of cooling equipment and the description of wind speed field, which are suitable for the cold storage needs of a variety of goods. Equipped with perfect storage temperature active detection, recording and active control equipment.San Marcos,Clean the condenser. The condenser is used as the heat dissipation and condensation of the compressor. Because it works in the outdoor environment, in the face of nature and for a long time, the condenser will be covered with a lot of dust and other foreign matters. These dust are firmly attached to the fins. If it is not handled manually it is difficult to fall off. It can be diluted with cleaning agent according to a certain proportion, and evenly sprayed on the fins with a spray can. After waiting for minutes, it can be washed with clean water. If it is still not clean, the above can be repeated until the fins are clean.Polystyrene foam: polystyrene foam is a new type of synthetic thermal insulation material. It is a kind of plastic, light weight, strong heat insulation effect and excellent low temperature resistance. However, due to its cold shrinkage, it is not very convenient for installation.Abay,First, use a hammer to pad the wood on the polyurethane warehouse board between the two warehouse boards, so as to make the boards closely close to each other. Two sets of connecting pieces shall be wedged between the wall panel and the wall panel, and the two sets of connecting pieces shall be fixed on the upper, outer and lower sides of the gap between the wall panel and the wall panel respectively. The lower connecting piece shall be as close as possible to the lower side, so that the post cast concrete can cover the connecting piece. After the gap between the plate and the plate ground is wedged with a connector, it shall be about mm wide. If it does not meet the requirements, remove the plate, trim the plate edge, and then reinstall it to make the plate joint meet the requirements. When fixing the adapter, pay attention to fix the two parts of the adapter on the edges of the convex and concave library plates respectively, and fix them with rivets. The spacing of the adapter should be able to tension the two library plates. When wedging the wedge iron, the hammer shall be perpendicular to the wedge iron to prevent damaging the warehouse plate. The ground wedge iron at the upper and lower parts shall be wedged at the same time, and the wedge iron shall be fixed with rivets.Frequently observe the operation state of the heart compressor of the cold storage equipment and its exhaust temperature. During the season change operation, pay special attention to the operation state of the system and adjust the liquid supply and condensation temperature of the system in time.Installation of unit electrical box: the unit electrical box shall be installed near the unit; Vertical installation. If the unit is installed on the top of the warehouse, mainly to condense the refrigerant. The high-pressure temperature can reach Baidu, and the temperature will drop to degrees after condensation.Now let's analyze the production and use requirements of the cold storage. There is no condensation in the cold storage. Condensation in the cold storage or in the insulation layer is harmful. During the drying process of the new wall or under winter conditions, when the water vapor with high indoor temperature migrates outdoors, it is impossible to condense in the wall due to the obstruction of the cold storage.Affordable price,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, whether it is a single-layer or double-layer warehouse, and the structure is the selection of steel structure or reinforcement solidification. Cold storage capacity, production process, refrigeration, temperature, etc. are used to determine the size and location of the cold storage room,San MarcosWhere is the cold storage installed, so that it can become a whole.There are many kinds of cold storage. According to the material, it can be divided into color steel plate, stainless steel plate and salted steel. Among them, color steel plate has strong anti rust ability, but stainless steel plate has strong anti rust ability, while salted steel has both beautiful appearance and anti rust ability. According to the layout it is divided into flat plate and wave plate. The former is flat after the surface material is formed, and the latter is rugged after the surface material is formed. According to the thickness and color of surface materials, the thickness of stainless steel is .mm and mm, without color requirements; The thickness of salted steel plate is .mm, without color requirements; The thickness of PE paint baking board is .mm, .mm ivory white, titanium white and white gray. The most important thing for the cold storage is the applicable temperature of the cold storage. It is divided according to the insulation thickness of the storage plate. The thickness of the sky floor of the mm storage plate is mm, and the thickness of the vertical plate is mm and mm, which is suitable for the insulation conditions of - ℃ ~ - ℃; mm storage plate: the thickness of the ceiling plate is mm and the thickness of the vertical plate is mm, which is suitable for the thermal insulation conditions of ℃ ~ - ℃. The thickness of the ceiling plate and the vertical plate of mm storage plate is mm,San MarcosVegetable cold storage equipment installation, which is suitable for the thermal insulation conditions above ℃. In fact,San MarcosConstruction and installation of cold storage, there are many other classification methods of cold storage. Determined by the current processing technology, it can be divided into standard plate and non-standard plate according to the width and size range of warehouse plate, including standard plate vertical plate width wa = mm, heaven and earth plate width WB = mm, vertical angle plate W = mm, W = mm W = mm and W = . The dimensions of non-standard plates are different from those of Wa, the uneven part shall be leveled with materials WB and W. - precautions for floor installation of cold storage: the floor shall be installed flat, 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).

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,Acid disinfectant can be used for mold removal and disinfection of quick-frozen warehouse.Scroll refrigeration unit: at present I hope you must pay attention to defrosting.Energy costs, scroll refrigeration unit is mainly in fully enclosed structure, which is mainly used in air conditioning (heat pump)The drainage at the outlet of the cooling fan, but indirect drainage shall be adopted. For the flushing (thawing) water drainage of each layer in the double-layer cold storage, an exhaust valve equipment shall be set in front of the main riser for flushing (thawing) water drainage.San Marcos,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.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 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.
