Phenolic foam sandwich panel is produce on a continuous production line, the lower layer is a soft material such as nonwoven fabric, a sandwich is a phenolic intermediate of the process technology of sandwich board special equipment, and the specification of a sandwich panel having a thickness of 20 to 100 mm, a width of 1200 mm, the length of the self - identification.The operation principle is as follows:Phenolic foam stock solution by the metering pump of the filling machine in a definite proportion is fed into the mixing head are mixed uniformly cast sandwich plate in a bottom surface of said circuit, and on the dimensions and material into the laminating conveyor, in the laminated above and below the conveyor chain between the foamed and cured to form; and curing material because of the production line after forming of the sandwich on both sides after trimming is automatically tracking cutter according to the needs of the product is cut to length.
★ Main Technical Parameters
line speed of 1.5 to 5 m / min
Sheet thickness:20 - 100 mm
the stirring speed of 4500 r / min

The equipment consists of
This means two 由放料, 面材预 heating device, a low pressure foaming machine, a mobile machine, 贴侧 paper, laminated to a hot - air circulating device, a trimmer, a cutter roll and the like.
The four major equipment upgrades.
I. was used instead of plastic stoppers and aluminum stoppers, using self - developed 120 mm thick block, in the production of various specifications of the thickness of the sheet without the replacement block, and to save a set of paper device, to a great extent on the coating.
II, was used instead of the hydraulic lifting system, has been losing high screw elevator system, reduction in the total system power, thereby reducing the energy consumption of the elevator system to function more smoothly, freely, lifting size more precisely, in order to overcome the pressure of the hydraulic system unstable, inconsistent, so as to achieve simple operation, easy maintenance, easy maintenance.
III, an emptying device was used instead of the above arrangement, there are two unreeling devices are placed on the ground, so as to solve the problem of workshop of no service, and more easily to a reel, and the operation is more convenient, reduces the use of the investment cost.
IV. It adopts a new adjustable double mitre saw blade, so as to reach 900 mm, 1200 mm, 1800 mm and 2400 mm - four arbitrary adjustable length specification.
