Impregnated paper decorative wood-based panel
Wood-based panels, especially medium-density fiberboard and particleboard in wood-based panels, have lost their natural texture and monotonous color. However, after surface treatment, the surface can be beautiful, the color is rich, and the decorative effect is improved. At the same time, after surface decoration, the surface will have good wear resistance, water resistance, heat resistance, weather resistance and corrosion resistance. Correspondingly, the static bending strength, stiffness and tensile strength of the sheet after the veneer treatment are improved, and the chemical stability will also be improved.
There are many methods for surface decoration of wood-based panels, one of which is to cover the surface with impregnated paper.
The impregnated paper veneer of the wood-based panel is directly attached to the surface of the artificial board by various special adhesive film impregnated with synthetic resin. After this method, the quality of the board surface is good, the process is simple, and the cost is low, so the impregnated paper veneer is more and more widely used for the artificial board veneer.
The process of artificial board impregnated paper veneer is divided into two parts: one is to make impregnated film paper, and the other is to laminate the artificial board with the impregnated film paper.
Examples of the immersion overlay paper include melamine resin impregnated paper, phenolic aldehyde resin impregnated paper, polybutylene phthalate resin impregnated paper, and guano resin impregnated paper. Among them, melamine resin impregnated paper is a kind of veneer material which is widely used at present. The melamine resin is a high-pressure resin that directly attaches the impregnated paper to the surface of the artificial board at a low pressure. This can save a hot supply and demand, shorten the production cycle, improve production efficiency, reduce production costs, and good veneer quality.
Paper-Plastic Composite Bags are made of the composite plastic Woven Bag and kraft paper, plastic layer usually use polypropylene (PP) or polyethylene (PE) as the backing material of flat wire woven cloth, refined composite special kraft paper. Is one of the most popular packaging materials, widely used in plastic materials, cement, feed, chemical, fertilizer and other industries.
Process description: adopts refined white kraft paper or yellow kraft paper outside and the inside plastic woven cloth, make through high temperature and high pressure plastic particles PP melt, kraft paper and plastic woven cloth composite together. Can add lining of the bag. The form of paper plastic compound bag is equal to the opening pocket of the seam. It has the advantages of good strength, waterproof and damp proof.
