The raw materials of the integrated wall should be made from brand-new wood powder, bamboo powder, resin, other environmental protection additives and polymer materials
2. Basic structure
(1. Thickness) The overall thickness of the board is designed to be 1mm, which is the most suitable thickness after research. At the same time, the thickness difference between the top and bottom of the male and female grooves (the joints on both sides of the board) is 1 mm.
(2) The back surface adopts the Great Wall-shaped concave-convex surface with a depth of 2mm, which plays a role in strengthening the plate and can effectively restrain the deformation caused by thermal expansion and cold contraction. Function 2. Reasonable width and depth can make the water vapor condensed on the wall produce the best convection mode to distribute.
(3, middle hole) Function 1. The middle hole is conducive to circulating and convection of indoor air, so as to make the indoor environment clear and dry. Function 2. The middle hole makes the wall surface double-layered, resulting in double-layered medium protection (the sound in physics is transmitted through the medium), which is more conducive to the effect of sound insulation and heat preservation.
(4) * * * edging) 1. * * * edging is the setting edge of our unique national patent structure, and the air nail gun is driven into the brick wall to fix the edge, which is convenient to install and fast in construction; 2. A unique V-shaped joint is adopted at the edge seam of the arch extrusion, which cleverly avoids the gap caused by thermal expansion and cold contraction from greatly affecting the aesthetic effect.
(5) film covering: the thickness of PVC films we choose is higher than 14 wires, and most of them use 16 wires, and a large number of high-end imported brand-new materials are used. All the laminating adhesives are made of environmentally-friendly two-component wallboard adhesives prepared from raw materials imported from Korea, which are environmentally-friendly and formaldehyde-free. Although the operation process of imported glue is complicated and slow, we always insist on using it for environmental protection.
Third, the odd structural advantages of the wall
(1. The difference between thickness and thickness is about 1mm, which is too thin to cut corners and is not conducive to compression resistance. Too thick waste, and heavy, lack of toughness, is not conducive to installation and service life.
(2) Some grooves on the back are not 2mm, or even some have no grooves on the back, which is easy to cause bulging deformation due to thermal expansion and contraction, and at the same time, the indoor air is not circulated.
(3) The spacing and size of sound insulation holes are also very important. If it is large, it will cause insufficient compression shape of the board, and its toughness is also true. If it is small, it will cause inconvenience to air convection. However, the odd middle hole of the board is just in line with the national practical patent structure, which can not only play the role of sound insulation, but also play the role of ventilation and convection. At the same time, it does not affect the use of functions such as compression resistance and impact resistance of the plate.
(4) Many company products have no * * * edging, or * * * edging adopts linear interface board (commonly known as seamless board). This will make the installation very inconvenient, and after installation, the gap between thermal expansion and cold contraction is quite obvious, which seriously affects the appearance, and the V-shaped interface with odd walls cleverly avoids this kind of influence.
(5) Our company adopts special two-component wallboard adhesive for environmental protection and formaldehyde-free high-temperature laminating technology. Although the operation process is complicated and slow, we always insist on using it for environmental protection.
However, in order to pursue speed unilaterally, some manufacturers do not hesitate to sacrifice environmental protection, and adopt cheap one-component glue rich in formaldehyde, which not only affects the physical and mental health of operators, but also makes products with strong odor and high formaldehyde content.
fourth, how to distinguish the quality of bamboo fiber wall?
look, smell, ask and cut
look: look at the color, the thickness and the structure. High-quality plates are generally beige, that is, they tend to be bamboo and wood. There are no black spots and particles at the incision. If the color is black or spotted, it may be made of recycled materials, or the formula is problematic, which is not environmentally friendly and not durable. If the color is white, too much calcium powder is added and the toughness of the plate is not enough. In addition, it also depends on the thickness and structure. The thickness is generally 1 mm. The version structure adopts a groove combined with a soundproof hole, and at the same time, it has a * * * edging, which presents a V-shaped groove when splicing.
smell: the normal board smells close to the nostrils, with a faint smell of bamboo and wood. When the fire is lit, there is no open flame, and it is accompanied by a light smell of bamboo and wood and resin. Inferior plates smell obvious PVC stench.
q: ask the other company whether it can issue patent certificate, production license and product quality inspection certificate. Whether these documents are issued by state authorities. At the same time, ask the other party whether the after-sales warranty method, after-sales duration and after-sales scope are written in the contract.
cut: weigh the weight of the plate by hand, if it is too light, it will be seriously foamed. Too much calcium powder is added if it is too heavy. Take a 3-meter-long plate and try to bend it. If it can form a circle at 36 degrees, it means that the toughness and quality are up to standard, and the inferior plate will be too brittle and broken. In addition, see if the plates in the exhibition hall can be folded 9 degrees when installed. High-quality plates can be folded at 9 degrees, and inferior plates will crack when folded at 9 degrees.
