The 36-meter-long double-track is one of the very long crawler-type machines in China. It promotes a more complete chemical reaction between polyol and isocyanate, and the molecular structure is stronger, effectively ensuring heat insulation and stability.
1. Compared with the traditional cold storage board manufacturers, the hardware equipment is relatively backward, mainly using manual mold, manual film pressing and manual handling.
2. Class II fire rating
Fires caused by insulation quality problems are common. The "11.15" major fire accident in Shanghai was caused by the procurement and use of low-quality, non-flame-retardant polyurethane materials by the engineering contractor. At present, the state attaches great importance to security, this red line must not be broken. In the event of an accident, the manufacturer and the engineer shall be responsible.
At present, the B- grade polyurethane cold storage board materials of cold storage board manufacturers involve black materials, white materials, catalysts, foaming agents, flame retardants, foam homogenizers and other raw materials; traditional cold storage boards generally use black materials and white materials to foam. Considering the huge difference of raw materials and foaming equipment, the introduction coefficient of the mechanism cold storage board is 0.018-0.024w/(m · K), which has excellent heat preservation and fire resistance, while the flame retardant performance of the traditional cold storage board is significantly lower than that of the mechanism cold storage board.
3. Energy saving and environmental protection
The reason why the cold storage of the cold storage board manufacturer cannot reach the required temperature is not only the refrigerator and the number of door openings, but also whether the storage board itself is insulated.
Cold storage board manufacturer's cold storage board: the whole process of the equipment is controlled by computer, using high-precision machine tools, six components of environmental protection pentane
Continuous uniform foaming, polyurethane closed cell rate of more than 97%, high adhesion. Due to its strict foaming system, the entire foaming process is uniform, the density of each point is basically the same, and the heat preservation effect is far better than the traditional cold storage board.
Traditional cold storage plate: intermittent production, put the steel plates on both sides of the cold storage plate into the mold, and insert the foaming gun into the mold for foaming. In short, it is manual foaming. However, for a cold storage plate having a length, if the fluidity of the polyurethane does not meet the requirements, it will cause hollowing in the middle of the cold storage plate, uneven foaming, and low battery sealing rate, resulting in poor heat insulation performance. Since the outside of the board is a color steel plate, only by tearing the color steel plate can you directly see the holes in the polyurethane inside, which will seriously affect the heat insulation performance of the cold storage.
4. Delivery speed
Cold storage board manufacturers of cold storage board: a single day can produce about 5000 square meters. The length of the circuit board can be determined. As long as it is within the allowable transportation range, it can be produced. Products are mainly used in large and medium-sized cold storage engineering.
Traditional cold storage board: 400 ㎡ - 800 ㎡ per day, which is usually used to build indoor small cold storage.
