What brand of advertising board, KT board, card board?
The first is: raw material is foam plate core PS particles, but because of the cold plate are single core board, so to double the first foam, foam thickness is about 3.5mm, for half a month, then second times the core equipment in the foam, foam to the left and right 5.0-5.2mm, second may direct foaming after laminating glue.Then paste dough dough: the substrate is PVC, usually 0.08m-0.1mm, 0.9 x 2.4 "is mostly used 0.08-0.1mm 1.2 * 2.4 pieces of dough plate 0.16mm is generally used to strengthen the stiffness of the plate, because the surface is PVC, PS is the core material, so the choice must be neutral in the dough and glue, glue at the same time, each plate core glue paste, paste to the plate hydraulic machine (ten tons) extrusion, 24 hours can be taken out cutting edge trimming and packaging and shipment.Bubble: the wrapper and the plate core foaming, cause analysis1, the core ripening period is too short; 2, neutral glue problems or glue is wrong; 3, after the board has direct sunlight or ultraviolet light irradiation. The common bubble is due the dough is too thin, the sun after foaming, photo frame and dough little bubble, from the theoretical analysis of very easy blistering.
KT is composed of a PS particle generation after foam plate core, a new type of material surface after laminating pressing and KT from the current production of relatively mature technology can be divided into cold and hot composite compound, the two kinds of process for production of the corresponding products we called cold (cold composite plate) (hot plate and composite plate) hot plate.
