Anonymous users2024-01-23Laminate flooring is a wood-derived material, and its structure is like a sandwich, which is divided into four layers: wear-resistant layer, decorative layer, substrate layer and moisture-proof layer.
The wear-resistant layer is the most superficial transparent layer, and the red sapphire body of its raw material is aluminum oxide (AL2O3). The decorative layer, that is, the intimate and realistic wood grain decorative layer of the floor surface as seen by the naked eye. The substrate layer, also known as the middle layer, is crushed by natural or artificial fast-growing forest wood, and formed by fiber structure reorganization at high temperature and high pressure.
It is divided into high-density board, medium-density board and particleboard. The moisture barrier is the surface layer on the back of the floor. Polymer resin material is used and glued to the bottom surface of the substrate to play a role in stability and moisture-proofing.
The choice of laminate flooring is mainly based on the concave and convex grooves, environmental protection index and decors. The degree of occlusion of the concave and convex grooves determines the wear resistance and service life of laminate flooring.
Laminate flooring is enough to use wear-resistant revolutions above 6000 rpm, and the lowest standard laminate flooring on the market has also reached this standard, but the quality problems of the floor often appear in the gaps. Due to the loose and wide occlusion of the concave and convex grooves, gaps appear in the degumming of the floor after a period of use, and after the water, moisture and dust enter the gaps, the floor is deformed and warped, which will affect the use effect and service life.
The environmental protection index refers to the formaldehyde emission of laminate flooring. Formaldehyde is an indispensable substance for bonding in the production process of flooring, and it is also the most important pollutant. If the quality of the floor is not good and the joints are not tight enough, more formaldehyde will be released, which will affect human health.
At present, the domestic standard for formaldehyde release is 30 mg per 100 grams, and the international standard is 8 mg per 100 grams.
Laminate flooring has the advantages of wear resistance, stain resistance, scalding resistance, compression resistance, convenient construction, easy maintenance, not easy to deform, and rich colors. The disadvantage is that the environmentally friendly type is not as good as the solid wood floor, and the foot feel ratio is relatively poor.

Anonymous users2024-01-22GB T18102 2007 (National Standard for Impregnated Paper Laminated Wood Flooring) Definition: A layer or multiple layers of special paper impregnated with thermosetting amino resin, paved on the surface of particleboard, high-density fiberboard and other wood-based board substrates, with a balance layer on the back and a wear-resistant layer on the front, and a floor that has been hot-pressed and formed, the trade name is laminate flooring.
Machining technology: The above definition should be clearly described.
The difference between laminate flooring and solid wood flooring: laminate flooring is wear-resistant, has a long service life, has more colors, is convenient to install, and has a wide range of applications; Solid wood flooring has a good foot feel, but it is easy to be deformed by moisture, is not wear-resistant, and the price is higher.
The processing technology of solid wood flooring includes (main processes): sawn timber, aging, health and drying, four-sided planing, grinding and lacquering and other processes. ^_
1. Natural phenomena.
The color difference of sports wood flooring is a normal natural phenomenon. For example, the natural wood color is different due to the different growth environment of solid wood species. In addition, even the same log has different colors in different growth parts. >>>More
Solid wood parquet is composed of wear-resistant layer, decorative layer, base layer, balance layer, the front is sprayed with paint, which can completely seal the free formaldehyde in the plywood, and the problem is that the back of the parquet is generally not finished, and the free formaldehyde may be directly released after paving the floor, and then volatilized into the air through the gaps between the floors. >>>More
As the first conference on solid wood flooring for floor heating, for the problem of non-standard commercial names of solid wood flooring for floor heating, the "Industry Proposal on Standardizing the Standard Commercial Name of Solid Wood Flooring for Floor Heating" jointly issued by China Floor Network and Tiange was announced at this conference, calling for the standard abbreviation of the category "floor heating solid wood flooring" as the standard commercial name of the standard, and at the same time calling on relevant industry organizations and media to jointly adopt "floor heating solid wood flooring" when releasing official documents, news and relevant information for the public to ensure the accuracy and uniformity of information and effectively safeguard the informed rights and interests of consumers. >>>More
Liverpool's badge is more like a toilet, not the current flush toilet, but the kind of toilet that used to be emptied at night and during the day. >>>More
Same as above, it is a dry toilet, which refers specifically to a toilet without water for flushing. It's not that there is no top, it's not simple. The toilets in the building are also called toilets.
