1, the purchase of wood flooring, you should understand the main technical indicators: 1, wear indicators; 2, impact resistance; 3, stain resistance, stain; 4, anti-smoke burning; 5, the wear of the contact surface ; 6, chair casters scratch; 7, after absorbing water volume expansion; 8, formaldehyde emission.
2, how to understand the formaldehyde emission?
Formaldehyde is a chemical gas content in the air up to a certain concentration, it will cause harm to humans. It is mainly used in the manufacturing process of the composite material, from the adhesion. Such formaldehyde contained in the floor will not evaporate immediately, but slowly evaporate because of different temperature and humidity conditions, volatile time more than a decade. Permanent residence in the environment of excessive formaldehyde concentration of formaldehyde will be human eyes, nose, respiratory system or cause significant harm to people suffering from skin diseases. Animal experiments also showed that excessive formaldehyde emission also cause nasal and respiratory cancer.
Therefore, countries regarding formaldehyde emission plywood products have developed strict standards, such as Japan, the EU Community countries have regulations for every 100 grams of plywood formaldehyde emission must be less than or equal to 10 mg, otherwise not allowed to sale; about our plywood products formaldehyde emission standard (GB / T 18102-2000) regulations: a class (superior products) - per 100 grams of plywood formaldehyde emission must be less than or equal to 9 mg; class B (qualified) - per 100 grams of formaldehyde plywood release in more than 9 mg, less than 40 mg.
What do I need to install the floor?

4. Why must strictly regulate the installation conditions?
A: If you do not meet the specifications of the installation on the ground floor, will result in the following consequences: the floor from the dark, warped, uneven floor.
5, why should advance to the construction site survey?
A: professional and technical personnel in accordance with standards of investigation, is to ensure that the ground conditions are met before flooring installation specifications, to ensure the best installation results.
6, Q: why do we need at least 24 hour delivery system?
