Most of the wood furniture sold on the market, except for all solid wood furniture, has wood-based panel parts. Therefore, it is especially necessary to smell when you purchase. If you make people cry and sneeze, it means that the formaldehyde emission of the furniture is relatively high, there may be problems, do not buy.
First, look at the report:
Consumers request a quality inspection report from the dealer to see if the amount of formaldehyde released from the furniture is within the limits allowed by the standard. The national standard "Limits of Hazardous Substances in Wood Furniture for Interior Decoration Materials" stipulates that the amount of formaldehyde released in wooden furniture should not exceed 1.5 mg per liter. If the purchased wood furniture exceeds the standard, do not buy it. It is recommended to buy furniture that meets the requirements of e1 standard plate. Only plates that meet the e1 standard are truly harmless to the human body.
Second, look at the hardware connector hardware connector is the most intuitive quality standard, good hardware should be free, no noise, the surface coating does not peel off. The hardware of some high-grade panel furniture is imported, and the foreign language logo can be found on it. Because the freely disassemblable combination is the biggest advantage of panel furniture, the quality of the hardware connector is very important.
Metal parts require dexterity, smoothness, and good surface plating treatment. There should be no rust, burrs, etc., and the precision of the fittings should be high. Plastic parts should be beautiful in appearance and bright in color. The parts of the force should be strong and flexible, and should not be too thin. The open connector requires flexible rotation so that it will be smooth, easy and free of friction during opening and use.
Third, look at the edge of the veneer carefully looking for the quality of the edge of the furniture to a large extent. The first is the pros and cons of the edge-sealing material, and secondly, it is necessary to pay attention to whether the edge-sealing is uneven or lifted. Good edge sealing should be tightly stitched with the whole piece of sheet.
The veneer material has a great influence on the furniture grade. To touch the surface paint film, the general high-grade panel furniture is solid wood veneer, the middle file is paper veneer, and the price is lower at one time and the surface is rubber veneer. Among them, the paper veneer has different grades due to different processing techniques.
4. Look at the quality of the sheet. Check carefully whether the glue on the side and the surface of the sheet is evenly coated, whether the bond is firm, whether the trimming is smooth and smooth, and whether the end of the visible part such as the side panel, the door panel, the drawer panel, etc. Edge sealing, the edges of the well-decorated sheet can not touch the traces of bonding.
Assembling the combination mainly depends on whether the hole at the drilling hole is exquisite and tidy. Whether the connecting piece is firm after installation, whether there is a gap between the plane and the end face after the T-shaped joint is connected, whether there is looseness by hand.
Fifth, look at the size of the furniture market is currently mainly based on complete sets of bedroom furniture and office furniture, in addition to multi-functional film and television electrical cabinets and other products. National standards for the main dimensions of furniture are subject to regulatory requirements.
For example, the depth of the space in the hanging closet should be 530 mm or more, the height of the table furniture should be 680 mm to 760 mm, and the height of the bookcase should be greater than or equal to 230 mm to 310 mm.
Consumers need to understand these main dimensions most, because if the furniture is smaller than the specified size, it will cause a lot of inconvenience when used. If the depth of the large wardrobe space is too small, it will affect the hanging clothes, causing the door to close.
Six, ask the price:
Most of the wood furniture with excessive formaldehyde is made of cheap artificial boards, so the price of the whole set of wooden furniture is often "ultra-low". Due to the intensive use of inferior glue in cheap man-made boards, the amount of formaldehyde released is seriously exceeded.
Seven, sign the contract:
When customers purchase furniture, it is best to sign the "Furniture Sale Contract" and write the environmental protection clause into the contract.
Nowadays, a large number of consumers are tempted by low-cost dealers, taking white bars, receipts, etc., and when they go out of complaints about quality problems, such informal invoices are often difficult to use as valid evidence, so they buy The furniture must be issued by the dealer with a formal invoice.
Solid wood furniture purchase tips:
In fact, in the process of purchasing furniture, asking price, checking size, signing contracts, and invoicing are all indispensable links. Here, Xiaobian mainly focuses on materials to provide you with some purchasing skills. At present, the solid wood furniture on the market is varied, and consumers should be more cautious in the purchase process.
First, verify that the solid wood judges whether it is a mystery of solid wood furniture: wood grain and crusting, mainly watching the door panel and side panels.
Tips: crusting, wood grain and cross section.
Scarred: Look at the location of the scared side, and then find the corresponding pattern on the other side.
Wood grain: The appearance looks like a pattern, so the position corresponding to the change of the pattern corresponds to the corresponding pattern on the back of the cabinet door. If the correspondence is very good, it is pure solid wood.
Section: The color of the section is deeper than the panel, and it can be seen that it is made of whole piece of wood.
Second, judging tree species This is a factor that directly affects price and quality.
Ordinary solid wood furniture usually uses eucalyptus, white oak, ash, eucalyptus, eucalyptus, rubber wood, eucalyptus, while precious mahogany furniture mainly uses rosewood, wenge, and rosewood.
The market for solid wood furniture is rather chaotic, and there are often things that are shoddy and confusing trees. It is best to buy brand-name products. At the same time, it should be noted that the price of wood is rising day by day, and it is absolutely cheap to be too cheap.
From the cheapest pine, eucalyptus, to expensive mahogany, the price difference is dozens of times. Therefore, do not consider the tree species because it is solid wood. After all, solid wood like pine wood, in addition to environmental protection, performance is much worse than the artificial board.
Third, observe the wood to open the furniture cabinet door, drawer, observe whether the wood is dry, white, whether the texture is tight and delicate. If you have furniture made of materials such as particle board, MDF and one-time forming board, open the door or drawer and smell it for a pungent smell.
4. Look for the main force-receiving parts of the defective furniture, such as the column and the load-bearing horizontal strip connecting the column near the ground. There should be no large knots or cracks. The structure is firm, the frame must not be loose, and it is not allowed to break or break the material.
The components of the wood-based panels used in the furniture shall be edge-sealed, and the various accessories shall be installed with few pieces, missing nails and nails.
Pay attention to the details when you buy:
Several major defects of solid wood: cracking, crusting, insect eyes, mildew cracking: naturally can not buy.
Scarred: If there is a scar on the front, the same position on the back also has this knot. This knot is basically a dead knot. It takes a long time and will fall off. Therefore, furniture with such defects cannot be bought.
Insect eye: Although many furniture are said to have been dried and degreased, you think that China is so big, there are so many furniture factories, the state management is so weak, and the credibility must be at least 50%. In addition to those Western-style solid wood furniture, deliberately engraved on the insect eye, the other should not buy.
Mildew: It is the fact that the wood is green and has water marks. Although the sales aunt will tell you that it has been dried, no problem. But you think about it, after the moldy bread has been reprocessed, will you still eat it? The mildewed wood has a different performance than before.
V. Inspection strength The strength of the board surface can be pressed with a finger to feel the firmness of the board surface. One side of the material should have a well-shaped skeleton to fix. If the skeleton is sparse, the surface will feel empty and false, and the panel will vibrate greatly. The drawer bottom plate should be pressed by hand to test the strength. Generally, the bottom of the partition plate is multi-layered, and the area is large. The partition should be made of five-layer board.
Sixth, safety performance to observe whether there is a drawer or door frame tilt phenomenon, whether there is a slanting of the eye position caused by the twisted eye socket or the eye hole is too large, the hoe is not strict.
Wooden furniture should be safe and stable. When the two doors are opened 90 degrees, the hand should be gently pulled forward, and the cabinet should not be tilted forward automatically; the glass of the bookcase door should be edging; the mirror and The dressing table should be equipped with a back panel, and the bead should be fixed to the glass surface. Individual parts of the furniture (such as legs, drawers, doors or brackets) must have sufficient support. You can push the top corner of the furniture or sit on one side and try to make sure the furniture is firm.
7. Check the furniture with heavy interface. Add the protective block with screws in the corner position and stick it. As for the back plate part, it is also necessary to check whether it is set and the screws are attached.
Good solid wood furniture is connected by means of gutters, etc., where the local load is relatively large, it is also reinforced by screws and protective blocks. If you see solid wood furniture, all of which are fixed by screws, then the furniture is not strong enough. To judge the firmness of the furniture, you can judge by shaking the furniture and feeling the stability.
Sofa purchase notes:
1. Look at the quality of the frame. The two pieces of the sofa will be shaken and shaken repeatedly before and after the whole piece of the sofa. If the feeling is good, the frame is firm. Then discuss with the sales staff, uncover the corner of the lower base cloth, if there is no bad, no insects, no scars, no bark or wood wool, the hard and hard wood is made, and the connection between the material and the material is not Nailed with nails, but with the blink of an eye or the mouth of the mouth, and then glued, there is no problem.
2, look at the quality of the inner cushion layer. The bottom of the high-grade sofa seat and the back of the back are mostly made of nylon belt and snake spring cross-web structure. The upper layer is layered with high-elastic foam, sprayed cotton and light foam. This cushion rebounds well and feels comfortable. The mid-range sofa is mainly made of rubber fiberboard as the base and the bottom of the back. The upper layer is layered with medium density foam and sprayed cotton. This cushion has a harder sitting feel and a slightly less resilience.
3, look at fabrics, sewing to buy leather sofas to choose leather. The leather sofa is divided into a full-skin sofa and a half-skin sofa. Each set of leather sofas consumes 10 cows of cows. It has high value, good ventilation and environmental performance. It is widely used in developed countries such as Europe and America. The half-skin sofa replaces the cowhide with PU leather or artificial leather PVC on the back, bottom and other hidden parts of the sofa, but the direct contact part of the human body is still a higher value cowhide, which reduces the cost of the sofa and is more economical. The leather for the sofa is divided into yellow cowhide and buffalo leather, which are divided into the top layer skin, the second layer skin and the three layer skin according to the number of layers; the skin is divided into domestic skin and imported skin according to the origin. Imported skin imported from Italy and Germany with the best quality of the top layer of yellow cowhide, meets strict environmental requirements, high color fastness, good elasticity and breathability, high mechanical strength, especially high tear strength and tensile strength. High quality leather sofas must be top layer yellow cowhide. When purchasing a leather sofa, the leather surface should be rich and lustrous, no scars, and the texture of the texture should be fine. Use a fingertip to pinch a place to squat up. It should be soft and strong. After the sitting, the wrinkles can be disappeared or not obvious. The leather is fine and good.
When purchasing fabric sofas, it should be noted that the seat and back cover of the sofa should be a looper structure, and the high-grade fabric sofas usually have a cotton lining, and other dirt-prone parts should be replaced. The sofa fabric should be relatively thick, and its weight is more than 300 g/m2. It must be more durable, and it must be ensured that the surface is not more than 12,000 times. The sofa fabric can be divided into domestic and imported. The special fabrics for sofas produced by European and American professional manufacturers are of good quality, very small color difference, high color fastness, no weft of fabrics, especially some high-grade fabrics for improving antifouling ability, and the surface is also carried out. Special treatment. Imported high-grade fabrics also have antistatic, flame retardant and other functions. Buy fabric sofas to choose fabric latitude and longitude fine and smooth, no jump wire, no exposed joints, feels tense. Sewing depends on whether the stitches are even and straight, and the two hands are firmly pressed to see if the seams are tight and the sides of the teeth are round and full.
4, look at the cloth cloth to see whether the fabric is tightly attached to the internal filling, whether it is flat and flat, especially the two handrails and the seat, back joints to transition naturally, no creases. If it is a round and semi-circular handrail, it is necessary to see whether the arc is smooth, plump and beautiful. The fabric of the floral pattern or the checkered pattern depends on whether the flower shape of the splicing is consistent, whether the square is horizontal and vertical, and there is no inclination or distortion.
Finally sit down and try it out. I feel whether the inclination of the seat, the back or the curvature of the back seat are the same as the waist, back, buttocks and leg bends. Is the height of the pillow and the back suitable? The arms naturally extend and open in the usual time; the sitting feel is comfortable, and it is free when standing up. After standing up, look at the fabrics on the buttocks, backrest and sills for lashes that are noticeably slack and can't be recovered for a long time.
5, look at the choice of foam sponge high-grade sofa cushion should use a high-elastic foam sponge with a density of 30 kg / m3 or more, the back pad should use a high-elastic foam sponge with a density of 25 kg / m3 or more. In order to improve sitting comfort, some foams are softened without ensuring density reduction.
