PVC Foam Board Machine For Furniture , WPC PVC Foam Board Making
Machine Extrusion Line
Quick detail:
1.Rigid PVC foam products are foamed and molded with chemical
foaming agents. The blowing agent and its decomposition gas are
dissolved in the melt before entering extrusion die, then after
passing the extrusion die, the pressure and temperature in the melt
decreases, so that the gas dissolved in the melt is supersaturated
and phase separation occurs to form plenty of microbubbles. The
surface bubbles are fixed before they expand on the board surface
due to the rapid cooling of the cooling setting mold, then a dense
and smooth crust layer formed on the surface, thereby producing a
crust foam board.
2.The rigid PVC crust foam board adopts a restricted foaming
process. The melt is freely foamed from the clothes-hanger die, and
then introduced into a cooling station with a size similar to the
die, immediately forced cooling on the surface of the board to
suppress the surface area of the board foaming (crust) to obtain a
foamed semi-finished product with a relatively hard surface. After
passing through the cooling zone, it is drawn by the traction
device into the pressing roller device. In order to compensate for
the subsequent cooling shrinkage of the sheet, the size of the
cooling setting device is about 1% larger than the thickness of the
sheet. The cooling intensity of the cooling setting die is
different, and the thickness of the sheet skin is controlled to
vary between 0.1 mm and 1.0 mm.
Description of pvc board equipment:
1.pvc foam board extrusion machine is composed of Conical twin
screw extruder, board mould, sizing table, cooling bracket,
traction machine, cutting machine and other auxiliary machine.
2.Extruder is adopting special designed screw, the production line
adopt import famous electrical parts, such as siemens motor, ABB
inverter, Schneider and other brand. Our machine has high
performance, long service life.
3.PVC foam board have anticorrosive, moistureproof, mouldproof, not
bibulous, drilling, sawing, planing, easy to hot forming, hot
bending processing features, therefore widely used in furniture,
cabinets, bath cabinets and exhibition board, box core layer,
indoor and outdoor decoration, building materials, chemical
industry and other fields with boards, advertising signs, printing,
screen printing, spraying, computer lettering, electronic
instrument product packaging and other industries.
