Introduction

Impregnated film (commonly known as coated paper) is a special paper leaching amino resin (mainly melamine resin) or phenolic resin, and dried to a certain degree of curing of the dipped paper.

Application field

The dipped paper can be pressed or adhered to the surface of the wood-based panel by hot pressing.

Coated paper is widely used in the production of architectural  film faced construction plywoods, coated paper and wood-based panels by thermal pressure and the formation of building  film faced construction plywoods, its beautiful appearance, the obvious advantages: the building film surface makes the building smooth and smooth; Caused by any pollution; can strictly limit the amount of harmful gas emissions; wear, compression; waterproof paint greatly extended the life of the membrane.

Coated paper is divided into black coated paper and brown coated paper, with the production of the film so that the  film faced construction plywood can be repeated in the construction of the building inside and outside. Attached to its surface phenolic resin film with wear resistance, corrosion, compression characteristics of the surface smooth, smooth and easy to use, so as to avoid secondary plaster, greatly shortening the duration. Such a film is widely used in shear walls, dams, tunnels and so on. Has a wide range of development prospects.

Seven, 1530mm wide (effective width of 1510mm)

The reason why the film is delaminated

One may be the original paper is recycled paper, the paper itself is not good, so dipped when the dip is not uniform, there is no penetration, so the layer, the other in the hot when there is no pressure into one, in the demolition or use Film paper layer.

Second, it may be hot-tempered when the temperature is low, the paper is attached to the poor, there stratification.

Third, the film itself dipped when the glue is not good, affecting the paper itself attached to the uniformity of glue, resulting in open layer.
