The so-called powder patch is a patch made of wood powder on the surface of the wood. In short, it is putty made of sawdust and glue. It is used to repair holes or scratches in furniture wood. It plays a beautifying effect and has a very good effect. it is good. So it is a skill made by manufacturers and after-sales by merchants, but it will also become a fraudulent fraud by some unscrupulous mahogany manufacturers: There are two things that can't be separated from powder, one is wood flour, that is, sawdust; the other is binder. Of course, wood powder depends on the material of the furniture. The leaf sandalwood furniture uses the powder of the leaf sandalwood, and the acid branch uses the acid branch powder; there are many adhesives. When there was no chemical adhesive in the past, the lacquer was used, and now it is generally Both use 101 or 502. Some furniture factories use materials that are too inferior and need to be dyed in large areas, instead of 502 or 101. Putty putty, commonly known as iron putty, is used because the putty is dried and polished to be smooth and can be dyed casually. Not come out; 502 does not eat, so generally it will not be applied in large areas. Why Fanbu? In addition to the unscrupulous mahogany manufacturers, Fanbu is used as a fraud and deceitful method. In some normal mahogany furniture production, because of holes, stubble and other reasons, in order to play a beautifying effect, it needs to be supplemented. There are many reasons for the powder. There are generally the following aspects: Wood drying stage The wood needs to be broken into plates according to certain specifications, and can be used after being baked in a drying kiln for more than 25 days, otherwise it is easy to crack and bend. It's easy to understand here. When the wood is baked in the kiln, it must be cracked. If it is cracked, it will definitely not be used. When the opened material is made into a rough piece according to the furniture produced, because the internal stress of the wood is not released uniformly, it may be cracked during the manufacturing process. At this time, cracks can be avoided and can be avoided. Production stage The production steps are generally: carpentry-carver-carpentry-carver-scraper-carver-scraper-hot wax. The carpenter makes the rough, and then carves the carver (if this piece has carving). The equipment used in woodworking is mainly electric saws, hand saws, chisels, electric drills and milling machines. We know that the reason why mahogany is so popular is that these woods have good color, good feel, high hardness and high density. However, the higher the hardness, the more brittle. Therefore, in these complex manufacturing processes, each link may produce cracks, stubble, stubble, etc., especially milling machines and electric saws, it is very easy to produce stubble under high-speed movement. If you look at the size of the stubble, if it is very small, it can be polished later. If it is a little deeper, it may not be completely polished, so you can only make up. At this time, if the wood is discarded because of a little stubble, I think this is impossible. As a production company, it cannot be done like this, unless consumers are willing to pay for the wood and waste wages. . Carving part Carving hardwood, there will be a small chipping if careless. The fibers of some woods are not in the same direction, and some places have the growth of fibers interlaced. It is easy to drop the slag when carving in these places, so they can only be supplemented, there is no other way. Scrape The polishing of mahogany furniture is actually two parts. One is scraping, and the other is grinding. The jargon is called scraping. The specific steps depend on your personal habits. Some people are used to scraping and grinding, while others are used to scraping and grinding. A net planer on hardwood furniture is a meticulous work. When scraping, you must scrape along the growth direction of the wood fiber, the intensity should be consistent, and the speed should be uniform. But because the wood fiber growth direction is not the same. Therefore, when scraping, it is inevitable that there will be a collapse at the intersection of the two directions. If the collapse is small, it can be eliminated by grinding. If it is large, there will still be small pits after grinding, so it can only be repaired. Storage phase The so-called storage stage is the stage where the furniture has just been made and placed in a warehouse or shop for sale. The steps of making furniture are complicated. After the new furniture is made, there will be some stress in the interior. For example, the internal stress of wood and the stress of furniture tenon and mortise. When the temperature or humidity changes, these stresses will be quickly released, which causes small cracks at the joint of the tenon and mortise, or fine cracks in the direction of the fiber. At this time, the furniture has been completed, and some small cracks can only be repaired, so this is also a reason for the repair. However, relative to the above reasons, such compensation is still very small. A large area of ​​Fanbu is definitely not a normal mahogany craft, but a fraud and fraud! However, it is difficult to completely avoid small powder tonics. It can only be refined from the selection of materials to the production, and try to make it as few as possible. Of course, Fanbu is only a few phenomena in furniture. The mahogany furniture with no patching and Fanbu is still the mainstream, but the cost is higher. On the premise of not affecting the appearance and quality, some small powder supplements are normal.
