With the increasing awareness of environmental protection, more and more consumers are hoping to purchase green and environmentally-friendly wooden furniture when purchasing furniture. The furniture sellers on the market have also launched signs such as solid wood and green certification, which makes it difficult to distinguish between authenticity and authenticity. . In recent years, some furniture that has been made using skin-laying techniques has been sold as mahogany furniture, so everyone can be careful. Look for flaws Now, the low-grade wood furniture has a higher level of leather, and the skin is more and more realistic. It is difficult for consumers to distinguish it at the moment. For example, the door panel, the panel, the side panel, etc. are covered with musk wood, the core wood is medium density board, or low. The MDF and particleboard are used as the “coreâ€, and the exterior is covered with precious wood, and then the price of solid wood furniture is marked. Usually the leather on the mahogany furniture will not be covered with leather. Generally, the big side and the rag are made of real materials. The complicated parts of the line are real materials. Usually the skin will be used on the core board, and both sides must be Sticky skin, but the texture of the wood is not exactly the same on both sides. By carefully distinguishing the wood grain, you can always see the flaws. In addition, the leather furniture is not hot wax, because the hot wax will make the skin foaming. Generally use a thin layer of wax or walnut oil or a lacquer. Smell to identify Furniture veneer, must use glue, we also have identification. The traditional skinning process uses pig gutta-percha, why do you make pig gutta-percha? Because it will foam when wrinkled, you can use the pig gutta-percha, you can drive the air out, take a soldering iron and iron it very flat, and the general chemical glue Can't do it. Identify the pig's rubber, you can rub it with your hands, heat the surface, take a nose and smell it. If you paint, the method of smelling is not good, but you can smell the back, often the front side of the core board is painted and the back is not. Listening to sound The mahogany skin is not used for wood. It is often used with lower density pears, rosewoods (white twigs, squid), etc., and can be distinguished by the sound when tapping. Generally, the high-density mahogany has "the hall sound", which is the echo of the snoring sound. Just as the ringtone of the mobile phone now has chords, it is a kind of sweet and crisp sound; while the low-density mahogany, such as the rosewood, is only very brittle.啪啪" sound. Touching temperature It is also a way to identify the density of wood by touching the surface of the furniture to determine the change in temperature. Generally, the density of wood is high, and the heat transfer is fast. The touch will feel cooler in a moment; the heat transfer is slower than the less dense wood, and the temperature is higher. Experts suggest that when choosing solid wood furniture, consumers should choose some products with big after-sales service and good reputation. Solid wood furniture is also related to personal care, such as sun exposure, too cold or too hot, too dry and humid environment can also lead to deformation, cracking and other phenomena.

Especially with the emergence of microprocessors and the continuous improvement of industrial automation technology, load cells have become a necessary device in process control.
From the weight measurement of large tanks and hoppers that could not be weighed before, and the measurement and control of crane scales, automobile scales, etc., to the batching system for mixing and distributing a variety of raw materials, automatic detection in the production process, and control of the powder and granular material feed volume, etc., Have applied the load cell.
At present, load cells are mainly used in various electronic weighing instruments, industrial control fields, online control, installation overload alarms, material testing machines, and other fields, such as electronic truck scales, electronic platform scales, electronic forklifts, dynamic axle load scales, electronic hook scales, etc., Electronic pricing scales, electronic steel scales, electronic rail scales, hopper scales, batching scales, filling scales, etc.
