1. What are the main technical indicators that should be understood when purchasing composite wood flooring?
When purchasing composite wood flooring, the main technical indicators that should be understood are: 1. Wear resistance index; 2. Impact resistance; 3. Resistance to stains and stains; 4. Resistance to smoke; 5. Wear of contact surfaces; , Chair caster scratches; 7, after absorbing water, volume expansion rate; 8, formaldehyde emission.
2. How to understand formaldehyde emission?
Formaldehyde is a kind of chemical gas. When the air content reaches a certain concentration, it will cause harm to the human body. It is mainly used in the manufacturing process of composite materials and plays a role in adhesion. In this way, the formaldehyde contained in the floor will not evaporate immediately, but will slowly evaporate due to different temperature and humidity conditions, and the evaporation time will be more than ten years. Living in an environment where the concentration of formaldehyde is excessive for a long period of time, formaldehyde can cause significant damage to people's eyes, nose, and respiratory system or cause skin problems. The results of animal experiments also showed that excessive levels of formaldehyde release can also lead to cancer of the nasal cancer and respiratory system.
Therefore, all countries have set strict standards for the amount of formaldehyde released from plywood products. For example, Japan and the European Union (EU) countries require that the amount of formaldehyde released per 100 g of plywood must be less than or equal to 10 milligrams. Otherwise, it is not allowed to be sold on the market; China's relevant plywood products The formaldehyde emission standard (GB/T18102-2000) stipulates that the formaldehyde emission of Class A (excellent product)?D?D per 100 g of plywood must be less than or equal to 9 mg; Class B (qualified product)?D?D per 100 The amount of formaldehyde released from the plywood is greater than 9 milligrams and less than 40 milligrams.
3, installation should pay attention to what?
Answer: 1. Cannot be installed on uneven or wet floors, such as kitchens and bathrooms. 2, can not be installed on the newly laid concrete floor. 3. The cement floor should be air-conditioned for at least 80 days. 4. Use a polyethylene mat that is at least 2 mm thick. 5, can be laid on the plumbing ground, but can not be laid on the electric heating ground.
4. Why must strictly regulate the installation conditions?
Answer: If the floor is installed on the ground that does not meet the specifications, the following consequences will result: the floor will be kicked and lifted, and the floor will be uneven.
5. Why should we advance to the construction site survey?
A: Professionals and technicians perform surveys according to standards, in order to ensure that the ground conditions are in line with the specifications before the floor is installed and the best installation results are guaranteed.
6, Q: Why do we need to implement a 24-hour delivery system?
A: It is to allow the floor to adapt to the differences in temperature and humidity between the indoor and outdoor rooms of the user's room. After the installation, the floor will not be deformed and the installation quality will be guaranteed.
7. Q: What is the difference between composite wood flooring and solid wood flooring?
A: The biggest difference between composite wood flooring and solid wood flooring lies in its structure. Composite wood flooring is a composite structure with high surface abrasion resistance and good moisture resistance; while solid wood floors have a good foot feeling and feel luxurious after pavement, but time Longer tends to be deformed. Both of them have their own characteristics, but due to their unique advantages, composite wood flooring comes from fast-growing forests, which can protect the environment's natural resources to the greatest extent. Therefore, it has attracted many consumers worldwide, especially Environmentalists welcome. Since the birth of laminate flooring in 1985, sales volume has been rising rapidly. By 1998, it has reached 180 million m2. In the near future, it will most likely become the most important material for residential floor decoration.
8. The calculation formula for the number of baseboards required is:
The number of square meters of floor used in the room floor/2.4.
9. The formula for calculating the household cost for indoor installation of stairs is:
(The number of floors used in the room floor + the number of floors used in the stairs) ☆ unit price + stairs number ☆ 70 yuan.
10. Q: How to determine the purchase area when purchasing flooring?
A: Add about 8% of the loss to the actual area of ​​the house. The final settlement of the project is based on the actual installed square meters.
11, Q: What is the green core moisture function?
A: There are two main types of composite wood flooring substrates. One is particle board, and the other is small. 8. What is the advice? The small-diameter wood is crushed and glued to be pressed under high temperature and high pressure for the present. Universal. Among them, the density of MDF is 550kg-880kg/m3, and the density of high density board is ≥880kg/m3. "Ruijia" is a high-density board. Because the composite wood flooring core is wood, it is still afraid of water. For this reason, "Ruijia" flooring has added special moisture-proof additives to the production process of high-density boards, so that the water-absorbing thickness expansion rate of the floor is smaller and the common core layer is smaller and plays an all-round moisture-proof role. To show the difference, the moisture-proof core layer is usually dyed green, which is what the consumer sees as a green core floor.
12, Q: Is the green core moisture-proof floor not afraid of water?
A: Composite wood flooring is again moisture-proof, but also woody, wooden things are all afraid of water. Green core moisture-proof floor is mainly played by strengthening the role of moisture. Some composite wood floors can be soaked in water because these floors are over-grown with urea-formaldehyde resin glue or made with phenolphthalein rubber. However, increasing the urea formaldehyde resin will inevitably cause excessive formaldehyde, and the phenolphthalein rubber is highly toxic and is strictly prohibited in indoor use abroad.
13, Q: How to care.
Daily care is very simple, no need to polish, wax and paint, just use a vacuum cleaner or wipe with a damp cloth, mop. If you are accidentally soiled with nail polish, ink, or alcohol, use a nail polish remover or dishwashing liquid to clean it. Special Note: Do not use water to wash the floor; do not use strong corrosive cleaners to clean the floor, the wear layer is aluminum oxide, it is amphoteric oxide, can react with acid, but also with alkali reaction. Avoid alkaline substances, scrub with rice water is a good way. Avoid sanding, waxing or painting on the floor.
