Laminate flooring, full name parquet. It is a kind of flooring derived from the solid wood flooring family. It was first developed in Europe. It was introduced to China in the early and mid-1990s. It is generally divided into three layers: solid wood composite flooring and multi-layer solid wood composite flooring.
Many people now think that solid wood flooring is too expensive, so more and more people have turned to composite flooring, but many people are not very familiar with laminate flooring, do not know how to buy, today Xiaobian will give you a general popularity, buy composite Several indicators when the floor!
First, the amount of formaldehyde released
The amount of formaldehyde released refers to the environmental protection index of composite wood flooring. Formaldehyde is an indispensable substance for bonding in the production of composite wood flooring, and it is also the most important pollutant. The current national standard for formaldehyde release is 1.5 mg per 100 grams.
Second, the table and the degree of wear resistance
The national standard stipulates that the wear resistance number of household second-grade composite wood floor needs to be greater than 4000 rpm, the wear resistance number of household first-class composite wood floor needs to be greater than 6000 rpm, and the wear resistance number of composite wooden floor in public occasion needs to be greater than 9000 rpm.
Third, water absorption thickness expansion rate
This is one of the most important technical indicators of composite wood flooring. The thickness of the water absorption thickness is an important factor determining whether the composite wood floor will deform after being damp. The water absorption thickness expansion rate is high, and the composite wood floor has poor moisture resistance; the water absorption thickness expansion rate is low, and the composite wood floor quality is the best. Overall, composite wood flooring is still the most water-free use.
Fourth, the processing accuracy of the floor
Take two pieces of composite wood flooring together. The height difference of the joints by hand is quite sensible. The difference between brands should be obvious. The rigor of the splicing gap can be seen as the quality of the composite wood floor.
Fifth, the surface impact resistance
This is also one of the important indicators of the quality of composite wood flooring. This refers to the diameter of the trace of the composite wood floor after being impacted by the steel ball under the same conditions. The smaller the value, the stronger the impact resistance of the product.
Sixth, formal certificates and inspection reports
When consumers choose the floor, they must find out whether the business has relevant certificates and quality inspection reports. Relevant certificates generally include floor origin certificate, European Composite Flooring Association (eplf) certificate, iso9001 international quality certification, iso14001 international environmental certification, and other related quality certificates.
Seventh, after sales service
Laminate flooring generally requires professional installers to use special tools for wood floor installation, so consumers must ask if the merchant has a professional installation team, and can provide a formal warranty certificate and warranty card.
