Polyurethane sandwich panel production line?
Polyurethane sandwich board is polyurethane as the double metal surface and the insulation layer of the single metal surface, non metal surface composite board, commonly used in industrial workshop, warehouse logistics, integrated building wall, roof enclosure system.
Products are mainly used for exterior wall insulation and central air conditioning, air supply pipe. The working principle of polyurethane perfusion machine by measuring liquid pump in a certain proportion into the mixing head after mixing evenly pouring in sandwich bottom material, and the upper surface of a layer in the layer of transport to the press, press under the chain plates foam curing; sandwich plate after curing in the production line both sides trimmed, automatic track cutting machine cut to length of the products.
Polyurethane sandwich panel production line, namely polyurethane composite insulation board production line, is made up of two layers: cement, aluminum foil and non-woven,In the soft base material such as cloth and paper, special equipment for producing phenolic resin (polyurethane) foam sandwich board, the thickness of sandwich panel is 20-100mm, width 1200mm, length is fixed.
