Combination refrigerator door, the product name: a combination of two cold storage doors, Company Name: Shandong Hua Yu Machinery Co., Ltd. Third, introduce a combination refrigerator door: now producing 200 thick cold storage doors, Shandong Hua Yu Machinery Co., Ltd. combination refrigerator door Generally, there are two: one is the polyurethane foam injected into pre-made within a good framework, it is the use of insulation board. The production of combination cold storage doors, general use of polyurethane insulation panels, because it not only has great strength, and good thermal insulation. Combination door refrigerator door design is very important, but it is also crucial bearing design, should be given high priority. In combination refrigerator door systems currently used in the best kind of weight than the use of 150 thick door refrigerator door, the door is moved to the closed position automatically stuck. This design is a combination of the refrigerator door on the two corners of the door mounted in nylon bearings track containing a 90 ° angle of the slide, and has a special adjustable brake. A groove on the track, when the door is shut in place, nylon wheel fall into the recess of the door to stop the movement, and form a seal with the ground intact and door frame. Refrigerator door [Preferred] Shandong Huayu freezing cold mainly used for food processing and refrigeration 100mm refrigerator door, through artificial refrigeration, indoor maintain a certain low temperature. Cold walls, floors and laying a certain thickness topping all insulation materials to reduce external incoming heat. In order to reduce the absorption of solar radiation, the cold exterior walls painted white or light colored general. Thus cold building and general industrial and civil construction is different, has its unique structure. Cold storage buildings to prevent the spread of water vapor and air infiltration. Outdoor air not only increases the consumption of cold cold invasion, but also to the Treasury into the water, causing moisture condensation heat shield structure building structures, especially damp cold freeze damage to the door, so to set the moisture-proof insulation, make cold storage building has good sealing and moisture vapor barrier properties. Ground affected low temperature cold storage, soil moisture is easily frozen. After the soil due to the volume expansion of frozen ground will cause cracking and deformation of the entire building structure, severe cold will not be used. To this end, in addition to cold storage floor should have effective insulation layer, the lower insulating layer must be treated to prevent the soil from freezing.
