Fireproof plywood is a new advanced composite material, also known as high pressure decorative fireproof plywood. Because its back is very similar to wood material, some people think it is made of natural wood, but it is not. The fireproof plywood is divided into four layers from the back to the surface, which are: adhesive layer, base layer, decorative layer and protective layer. Among them, the adhesive layer and protective layer have the greatest impact on the quality of the fireproof plywood, and also determine the grade and the fireproof plywood price. When choosing a fireproof plywood, pay attention to its thickness. The thickness of the fireproof plywood is generally 0.6-1.2 mm, and the general thickness of veneer plywood is 0.7-1 mm. Also, pay attention to the appearance of the fireproof plywood (visually flawless from 1 meter away) and wear resistance, radiation resistance, dimensional stability, blistering time and other technical indicators. The technical properties of the fireproof plywood, such as boiling water resistance, high temperature resistance, and pollution resistance, are generally in line with the requirements, and there are not many quality problems.
Fireproof plywood and melamine plywood are the common cabinet door panel materials in the cabinet market at present, but many owners do not understand the difference between the two materials, and the sales staff of some plywood manufacturers also intentionally confuse the two materials and use melamine plywood is sold as fireproof plywood. In fact, there are certain differences between the two materials, which I will briefly introduce here.
Melamine plywood, also known as double-veneer plywood, one-time forming board. This kind of plywood is a paper printed with color or imitation wood grain, soaked in melamine transparent resin, and then pasted on the surface of the substrate to form by hot pressing. After the melamine resin is cured, the veneer has good physical properties such as wear resistance and scratch resistance, so it is more suitable for the requirements of kitchen furniture.
Fireproof plywood, its standard name is fireproof plywood. Fireproof plywood is just a habit of people say, but it is not really afraid of fire, but has a certain fire resistance. The fireproof door plywood is made of the fireproof board as the veneer, and the particle board as the base material (the MDF is also used), which is made after being pressed and pasted by the cabinet factory. Compared with melamine plywood, the processing of fireproof board is more troublesome. The melamine board can be cut directly, while the fireproof plywood needs to be sprayed with glue and pressed for more than a day with a platen press before it can be cut and used. Many decoration teams and cabinet factories do not have special machines to press the plywood, so they use some earth methods to press the plywood, and it is difficult to guarantee the quality. This also reminds owners and that if you choose a cabinet with fireproof door panels, it is also worth noting whether there is professional pressing equipment.
The veneer of the fireproof plywood is generally composed of three layers of surface paper, colored paper, and base paper (multi-layer kraft paper). The surface paper and colored paper are impregnated with melamine resin components, so that the fireproof plywood has physical properties such as wear resistance and scratch resistance. The multi-layer kraft paper makes the fireproof plywood have good impact resistance and flexibility.
It can be seen from the comparison diagram that the veneer of the fireproof plywood is three layers, which is relatively thick, while the veneer of the melamine plywood has only one layer. Therefore, in general, the wear resistance and scratch resistance of fireproof plywood are better than those of melamine plywood, and the price of melamine plywood is lower than that of fireproof plywood. Although both of them contain the same resin in the veneer material, the difference in thickness and structure leads to obvious differences in performance. The two cannot be generalized. Also imported melamine plywood are common in the market , whose surface with special treatment, in terms of wear resistance and other properties, it is more suitable for use in the kitchen environment than the general melamine plywood. Of course, the price is relatively high, close to or even higher than the price of fireproof plywood. Pay attention when choosing, it is also a good choice.
