European oak engineered flooring originated in the United States invented in the 1980s. The product is economical, maintains the original wood feel and has good deformation resistance. However, it has long occupied the mainstream position of the world's flooring material market and now has a 1/3 market share of wood flooring.
Next, let us introduce in detail the technical update of oak engineered flooring:
1 Surface resistance:
In the early stage of development, it is not wear-resistant. Due to UV paint, the surface of the floor is not wear-resistant and easy to scratch. Now with the development of UV paint technology, after adding wear-resistant agent to paint, the paint becomes a composite material. The addition of wear-resistant agent , Let the Engineering FLOORING have a protective film, and the number of friction-resistant revolutions has been increased from 500 to 4000 revolutions, which greatly saves the maintenance cost in the later period.
2 Size:
Before, the flooring plank has a single size choice, now there are multiple choices of size, you can choose the right one according to the room size, for example Big Plank: 2200*190mm*22mm/18mm/15mm 1900*190*14mm/18mm; Middle Plank: 1220*165* 14mm/12mm; Small Plank:
From the structure: 910*127*12mm/14mm, 450*90*15mm, 450*75*15mm; 510*92*15mm
3 Installation:
Due to the limitation of the locks at the start of the european oak flooring, only T&G locks can be used, which leads to the need for glue for installation, which is not only environmentally friendly, but also takes a long time. With economic development, labor costs increase, and people pay attention to the environment. The birth of the lock, UNILIN, VALINGE and I4F, greatly reduced the installation cost of the floor. Conducive to the rapid development of the overall multilayer flooring industry
4. Structure:
The multi-layer structure of quality inspection is just Veneer and multi-layer substrate board.
Now there are a variety of composite materials, the advantages of different materials of the structure, such as
Multilayer board substrate + laminate floor surface (Wear-resistant layer and melamine decorative paper);
Multilayer board substrate + HPL;
SPC + Veneer
1. Distinguish Method
Grade A: knots are not allowed;
Grade B：Quantity of knots per pc: 1-3pcs and the diameter of knots whose color are black is within 8mm and diameter of knots whose color are nearly same as veneer is within 10mm;
Grade C: Quantity of knots per pc: 1-3pcs and the diameter of knots whose color are black is within 20mm and diameter of knots whose color are nearly same as veneer is within 25mm; In addition, 20% of white edge of plank width is allowed and medium color variation is allowed;
Grade D: Quantity of knots per pc: 1-3pcs and the diameter of knots whose color are black is within 30mm and diameter of knots whose color are nearly same as veneer is unlimited; In addition, length of crack is within 30cm and severe color variation is allowed;
2.Percentage
ABC Grade: Percentage of grade AB: 15%, Percentage of grade C: 85%;
ABCD Grade: Percentage of grade AB: 20%, Percentage of grade C: 50%, Percentage of grade D: 30%
