Impregnation technology is a very important step during producing melamine impregnated paper. Below is the information of impregnation technology.
The glue is mixed by melamine resin and urea formaldehyde resin. The modifiers will be put into the mixed glue and stored in two acid resistance cylinders. Then the mixed glue will be delivered into impregnation production line by pipeline after adding hardeners, wetting agents, release agents and defoamers. The based paper is glued by urea formaldehyde resin at first time and dried by far-infrared. The second time the paper will be impregnated by melamine resin and dried by desiccant.
The last step is cut by the required size after the glued paper is cooling down.
