Reasons for Plywood degumming

 The film faced plywood board is made of multiple board skins bonded together and pressed by high temperature heating. It is inevitable that there will be problems during the processing. If bubbling and degumming occurs, what is the reason?


 

The reasons for this phenomenon are mainly concentrated in the selection of veneer, the choice of glue solvent and the control of hot pressing time. In the processing technology of veneer, the moisture content of the veneer and insufficient drying and charging will cause bubble. If the gluing solvent is applied too much, or the optimal temperature and time of the gluing solvent are exceeded, it will cause the plywood to open. The control of the hot pressing time is directly related to the dryness of the veneer, and the production personnel must ensure the reasonable use of the hot press and the veneer products to determine the best hot pressing time.


ZMADTO Plywood Co.Ltd is focus on construction plywood & wood formwork product.

Wood plastic composite is a kind of high-tech and environment-friendly composite material made of wood fiber and thermoplastics such as PE, PP, PVC, or PLA. After heating and extruding, it has properties and characteristics of both wood and plastic.    Wood-plastic flooring is made of  wpc decking  materials, with the same processing characteristics as wood. It can be sawed, drilled and nailed with ordinary tools and can be used like ordinary wood. At the same time, it has the texture of wood and the water resistance and corrosion resistance of plastic, making it a kind of excellent performance and very durable outdoor waterproof and anti-corrosion building material. Physical properties: good strength, high hardness, anti-slip, wear resistance, no cracking, no moth, low water absorption, aging resistance, corrosion resistance, anti-static and ultraviolet, insulation, heat insulation, flame retardant, can resist 75℃ high temperature and -40℃ low temperature. Environmental performance: e

How to Distinguish the Quality of Particle Board

图片
Particle board   has been widely used in home decoration. The furniture made by particle board manufacturers has a sense of hierarchy and clear texture. However, there are so many kinds of particle board products on the market. How to distinguish the quality of particle board when purchasing? Following us to know about it. 1. Appearance. Checking the product brand logo, the color of high-quality particle board is uniform. There is no obvious color difference and no points, block spots. Checking in the bright place, to see whether there are dry flowers, wet flowers, air bubbles, bulging and other problems, in a darker place, tilt the plate to check whether the surface is smooth or not and whether there are obvious seams and deformation problems. 2. Thickness and layer. A good substrate has a uniform thickness, good layering, no voids and overlaps. Secondly, depending on the thickness and material, measure the thickness of the board, the thickness of particle board is 15-18MM. 3. Product
