Real wood floors are made of natural materials - wood, made from mechanical equipment, which is characterized by natural materials - wood properties.
1, the trees,
The real wood floor can choose the tree species is very much, precious has rosewood, teak; Generally, there are maple, oak, ash, and gamba. The price difference is very big. When the choose and buy as far as possible choose colour plate, don't choose the colour board, try to choose material sex stability of tree species, avoid the wood floor appeared in the process of long-term use of ladle, twisting, bending, cracking, the phenomenon such as arch, ring.
2, size
Currently on the market supply of real wood floor, the sizes are longer, wider, such as 18 mm * 90 mm * 900 mm, in fact, floor of wood of appropriate short shoulds not belong, appropriate narrow shoulds not be wide, should choose is less than 600 mm x 75 mm x 18 mm of the floor, the smaller the size, the stronger the ability to resist deformation. If used for floor heating floor, appropriate thin should not be thick, generally 8 ~ 12mm thick.
3. Moisture content.
Wood floor moisture content is crucial. The moisture content of the floor must be consistent with the local equilibrium moisture content. Be sure to measure moisture content on the floor. If there is no moisture content meter, don't buy it. Equilibrium moisture content determination method is simple, in the exhibition hall first purchased varieties of moisture content, and then out of the detection of the purchased varieties wood floor moisture content, if both moisture content is only + 1% ~ 2%, belong to qualified products.
4. Machining accuracy
On flat ground assembled with 10 floors, with the hand touch, see its processing quality precision, finish whether level off, smooth, tenon, groove cooperates, installation gap, such as resistance to deformation slot assembly is fit.
5. Base material quality.
Check the floor level, whether there are worm eyes, cracking, decay, blue change, dead joints and other board defects. For small hinged, colour not too exacting, this is the natural attribute of lumber, as for the natural grain of lumber, the mostly tangential section is a small diameter section if both want the same section, more difficult to achieve in the real wood floor, unless it is sliced and veneer.
6. Paint quality
Whether it is lacquer, roller lacquer floor, commonly known as lacquer board; Whether light or inferior smooth paint floor, should view the paint on the surface of the plate when choosing QiMo whether smooth, plump, bright and clean, no leak paint, bubbling, perforation, among them as to put forward is wear-resisting degree, suggest that UV light curing coating of choose and buy, the market dealers or UV lacquer board, its abrasion resistance, resistance to hot burning performance are superior to another painting process. Burns 20 seconds with a cigarette end without leaving any trace.
B, solid wood composite floor.
The solid wood compound floor is general, in fact, it can be divided into multilayer solid wood laminate flooring, three-layers solid wood compound floor. The characteristic of this kind of floor: dimensional stability is better.
The appearance of 1.
Like real wood floor, the solid wood compound floor also divides into superior, first class, grade three kinds. Appearance quality is an important basis for grading. When the choose and buy, the first to see if wood surface colour, texture clear, the general surface should not have decayed, dead section, section, the wormhole, cleat resin, wood defects such as cracks or flat-fell seam is lax, sensory texture and colour and lustre of wood should be harmonious. At the same time, also should watch the tenon tongue around the floor and tenon groove is smooth.
Type 2.
The solid wood compound floor has two kinds, one kind is the three-floor solid wood floor, it is produced earlier, it is by table board, core board, backboard three layer board to make up together. Another kind of multilayer real wood floor is composed of seven or nine layers, the stability is better than three floors solid wood floor. Especially in the geothermal environment, the multilayer hardwood floor is more resistant to heat resistance and less deformation. Therefore, in order to purchase, it is necessary to find out whether to buy three floors or multi-layer solid wood composite floor. If you choose a geothermal floor, you have to choose layers.
Structure of 3.
When the consumer is shopping, through the four sides of the solid wood floor, you can see the structure of the veneer layers. The base material of traditional multilayer real wood floor adopts odd-layer group billet, usually seven or nine layers. In recent years, some brands have improved the traditional process and adopted even layer of blank, which is eight or ten layers. When the consumer is buying, might as well take the floor to pick up, look at the structure layer of the floor, the count is several layers.
4. Paint
The quality of the paint and the coating method are the important factors that determine the environmental protection, wear resistance and hardness of the floor. Floor paint should belong to environmental protection coating, should not contain halogenated hydrocarbon, heavy metal, formaldehyde and other harmful radioactivity.
In addition, the coating method of floor paint should also ask, the examination is clear. The six surface sealing paint off the floor, face, back, four sides should use UV lacquer and waterborne lacquer seal, play the role of tight waterproof moistureproof, prevent lacquer to fall off. The paint should be filled, full of colour, and resistant to hanging, not easy to fall off.
5. Formaldehyde content
Multilayer real wood floor board is composed of many pieces of wood veneer, the quality of floor adhesive, environmental protection performance is very important. Once the glue that is used is bad or even inferior, can make formaldehyde seriously exceed, affect the health of the user. At present, the compulsory standard for floor environmental protection in China is the E1 level, i.e., the average value of formaldehyde emission is lower than 1.5mg/L. Therefore, consumers should buy the floor at the E1 level so that they can be used safely.
Joining together of 6.
When the floor is taken, you can take more than 5 pieces of the floor in a box and place them on a glass surface or flat ground. After assembling, clap the tenon groove with the hand, observe the combination of the tenon groove, and then use the hand to feel whether it is smooth. Aftertouch, pick up two pieces of multi-layer solid wood composite floor in the hand sway, see whether it is loose, if there is high and low the hand feeling phenomenon and loosen phenomenon, explain this product is unqualified.
7. Install
The laying method of the solid wood composite floor has many kinds, no matter what kind of laid method should be standardized. And it's better to be the one who sells the clothes and avoid unnecessary prevarication and trouble. B&q provides professional floor laying service. Although the stability is the prominent advantage of the solid wood composite floor, the pavement of unscientific society directly affects the stability of the product. The so-called floor is not good, the installation is very important, only the installation procedure is standardized, the floor is used to be able to feel at ease, rest assured.
C, aggrandizement wood floor.
The scientific name is impregnated paper laminate flooring. It is a three-layer structure: the surface is impregnated with melamine resin impregnated paper with the wear-resistant material, the core layer is medium, high-density fiberboard or particleboard, and the bottom layer is the balanced paper impregnated with phenolic resin. The three layers are made of synthetic resin. The characteristics of such floor, wear resistance and dimensional stability is better.
1. Wear resistance.
Distinguish between good and bad through the comparison of the sample. The wear-resisting property of the heavier weight is better, and under normal circumstances, the larger the weight, the lower the sharpness of the wood grain paper. The floor of choose and buy does not want to choose colour very deep or black, because this kind of the floor of this kind of colour is wear-resisting property is poorer, or it is the surface clarity is not good.
2, design and colour
The variety of the design that chooses should be in harmony with indoor light and another colour photograph. Generally speaking, the place that the light is bad, unfavourable choose the colour of the colour of darker colour.
3. Product packaging
Through the comparison of product packaging to identify the pros and cons. The better product packaging logo comparison specification, has the factory name full name, the real factory address, the telephone, and indicates the product grade, the category and so on. To prevent fraud, consumers can check their phone Numbers.
4. Quality identification
The quality of floor quality is reflected in the base material, the colour wood grain paper, the wear-resisting layer and the product dimension precision several aspects. The smooth rate that can carry tenon chamfer position, fiber is fine even rate goes discerning the stand or fall of base material, through installing the discretion of the floor difference and flat-fell seam discern the stand or fall of product size precision, and design and color wood grain paper and wear-resisting layer to the naked eye cannot identify, suggested that packaging of choose normal manufacturer's product. Ask for service content. Through the service content and measures to ensure the implementation of the situation to determine whether the manufacturer is formal, so as to determine the quality of the product.
D. bamboo flooring
The bamboo floor has high density, good toughness, strong strength, strong and durable, easy to deform, smooth texture, soft colour, elegant and generous, green and green products. Its anti-mildew, mothproof, flame retardant, antistatic, no side effects and easy to install and other features, is a recognized new century decorative materials. The quality of bamboo floor is good or bad, mainly from two aspects.
1. It is the quality of the semi-finished product (blank).
2. It is the quality of finished product processing.
Semi-finished product: this should have a certain professional level to distinguish the quality of the semi-finished products, related to the majority of users the biggest concern. Whether cracking or deforming is also an important factor in determining the cost price of bamboo flooring. The three important parts of making semi-finished products are material selection, glue coating and hot pressing.
A. Material selection: good bamboo flooring and the selection of materials is strictly according to the label mining (the standard length of growth for each bamboo), and the bamboo of the same bamboo age when mining.
Advantage: good bamboo floor, expansion coefficient unity. The bamboo floor made of bamboo is not easy to crack and deform because of the contraction of bamboo.
Discrimination: with hands, the importance is relatively heavy. The bamboo fibre of each bamboo piece in the floor panel seems to be the same. It doesn't feel mouldy or black.
B, apply glue: good bamboo floor USES natural resin glue, environmental protection, glue sex is strong.
Poor bamboo flooring: chemical glue, adding a lot of curing agent. No need high-temperature curing, environmental protection poor, adhesion strength is not enough, easy to crack.
Identification: from the glued joint, or the bamboo strips, the resin adhesive high temperature is pressed in yellow or grey crystal, chemical glue, solid particles.
C, hot pressing and bonding: the pressure machine used for good bamboo flooring is generally 6 cylinders with a diameter of over 40cm, and the pressure is over 1500 tons. The temperature is at 120.
Discrimination: 1. It is best to ask the merchant to show the photo of the factory.
2. The hot pressure forming on the floor is relatively heavy, and the glue of bamboo and bamboo is relatively tight.
D. The process of finished products.
One, see the machining accuracy two, see paint quality.
Machining accuracy: good machining accuracy, the relation floor is high and low flatness, the joint seam is tight or not.
Distinguish: take out 6~8 pieces of floor, top and bottom two, middle four pieces, the high and low level is good.
See paint: distinguish: paint full, bright, smooth. No bubbles, particles. The hardness is relatively strong, encourage the waterborne paint bamboo floor, the environmental protection performance is good, the transparency is high.
E, cork floor
Cork floor actually does not use wood to make the floor, but the bark of cork tree is raw material, after grinding, hot pressing and become plank, the ground that is machined by machine equipment again.
This kind of plank looks similar to the soft thick plank, therefore, people mistakenly call it "cork" to continue until now, so people still call this floor is cork floor so far. Its characteristic is light, soft, sufficient feeling is good.
1. When choosing the cork floor, see whether the surface of the floor and is smooth, whether there are drums and convex particles, and whether the cork particles are pure.
2. See whether the side of the cork floor is straight, the method is: take 4 pieces of the same floor, spread on the glass, or the flat ground, assemble to see whether it is joint.
3. Check the bending strength of the board. The method is to close the two diagonals of the floor to see whether there is a crack in the curved surface, and there is no good quality.
4. Test of bonding strength. Will find the small piece of sample into open blisters, sanding smooth surface into a toad, uneven surfaces, the unqualified products, this product is excellent in boiling water surface have no obvious change.
