At present, the foam produced by the foaming machine of the polyurethane sandwich panel production line is a very good thermal insulation and energy-saving material, and its performance indicators are better than the traditional XPS and EPS external thermal insulation systems. This polyurethane equipment type exterior insulation system technology has attracted the attention of relevant leaders and experts from various states and cities across the country. Polyurethane sandwich panel production line foaming equipment is mainly used to produce polyurethane products, including hi...

1) Each uncoiler drives the sprocket through the hydraulic motor, and drives the main knot through the sprocket, so that the steel coil rotates with the main shaft, 2) To achieve the purpose of active unwinding. The base and frame of the uncoiler are all welded by rectangular tubes, which fully guarantees the rigidity of the equipment. 3) Reel: four pieces of nesting (shoes), available in 508 and 610 sizes, when 508 steel coil is switched to 610 inner hole steel coil, four arc plates are added to the original uncoiler to automatically support Tight and constant tension control; ...

This unit is used to preheat the upper and lower flexible fabrics to proper temperature. The PU/phenolic chemical reaction at a suitable temperature, the process of heating the flexible fabric promotes the activation of the PU/phenolic R, making the fabric and the foam layer more firm and reliable. The heating device uses a gas burner to heat the air and then blows the upper and lower layers of flexible fabrics. Temperature sensors are installed on the upper and lower layers to collect the current temperature in real time and adjust it to be close to the target set...

The upper and lower track shoes are the core of the double track press, and its design, material selection, machining and processing are very important and complicated. The double crawler machine is installed in the continuous production line, which is used for foaming and curing of the core material in the sandwich panel, and curing and shaping of the sandwich panel in the laminated state. When the track shoe is in working state, it needs to be under pressure for a long time (foaming pressure is 3kg/cm2) and temperature resistance (working temperature is 45ºC-80ºC), especiall...

Among all kinds of panels, sandwich panels are very common, and this is a very good panel. Although it is common, the production process is not simple. It requires the use of a large sandwich panel production line to be able to produce smoothly. It is necessary to know that the price of a production line is not cheap. In order to reduce costs, many manufacturers are also looking for ways to reduce costs as much as possible to achieve large profits. Let’s see if there is a good way. The pu sandwich panel line is expensive, because a production line is not just one piece of equipment, b...
