Solid wood furniture refers to furniture made of natural wood, and the texture of the wood is generally seen on the surface of the furniture. At present, there are two kinds of solid wood furniture on the market. One is pure solid wood furniture. All the materials of this kind of furniture are solid wood. The other is imitation wood furniture, which is the natural texture, feel and color of wood. They are the same as solid wood furniture, but they are actually furniture made of solid wood and wood-based panels. There is a solid wood dining table purchased by consumers. A friend who was recognized after one month found that it was not made of solid wood. The regular texture on the desktop reveals the true identity of the “solid wood dining tableâ€. “Besides the four legs and the frame are made of solid wood, the tabletop is actually made of wood-based panel veneer.†Why is solid wood furniture not all solid wood, solid wood homes have more "real"? How should consumers choose? The industry's unspoken rules of 60% solid wood is also solid wood furniture. According to the relevant person, the use of a variety of wood furniture is very common. Taking an ordinary wardrobe as an example, the materials of the panel and the backboard are different. The side panels and the bottom panel often do not use the same material. It is normal for a wardrobe to use six or seven kinds of wood. As long as the solid wood material exceeds 30%, some merchants will sell the "solid wood furniture" sign. Such as cabinets and wardrobes, as long as the door panels are solid wood, are known as solid wood cabinets and solid wood wardrobes, furniture is even more so, as long as the table legs, handrails are solid wood, are also marked as solid wood. However, this is labeled as "solid wood", but the actual furniture is only partially solid wood, the price can be several times more than the cost. “Sixty percent of solid wood†is indeed a “hidden rule†recognized by the furniture industry. According to industry insiders, the current "solid wood furniture" on the market is divided into two types: one is 100% solid wood furniture, and the other is "regular solid wood furniture", that is, about 60% of the furniture is made of solid wood. The remaining 40% are synthetic, reinforced and other synthetic materials, and most of these solid wood furniture are solid wood, solid wood, environmentally friendly solid wood, pure wood, logs and so on. A variety of names, responsible clerk will truthfully inform the materials and ingredients used in the furniture, and some sneak slick businesses not only do not inform, but also cover up, invisibly expand the scope of solid wood, in terms of price and quality Infringe on the consumer's right to know. Consumers are advised to purchase “completely solid wood†furniture without wood-based panels. Be sure to confirm with the sales staff at the time of purchase and indicate “100% solid wood†in the contract. The new national standard stipulates that 70% of solid wood can be called solid wood furniture. The definition of solid wood furniture is indeed very vague. Since May 1, 2009, the new version of "General Technical Conditions for Wood Furniture" was officially implemented. For the first time, the "solid wood furniture" was strictly defined. , "wooden panel furniture", "comprehensive wood furniture", "all solid wood furniture", "solid wood furniture" and "solid wood veneer furniture" specific definition. According to the "General Technical Conditions for Wood Furniture" jointly issued by the General Administration of Quality Supervision, Inspection and Quarantine and the National Standardization Administration, the furniture components must reach more than 70% of the solid wood standard to be called solid wood furniture. Some merchants said that "pure solid wood furniture", "log furniture", "environmental solid wood furniture", not mentioned in the national standards, although not a normative formulation, but consumers need to pay special attention to the word games. According to the mandatory national standard GB5296.6-2004 “Guidelines for the Use of Consumer Goods, Part 6: Furnitureâ€, the furniture sold must have instructions for use. The furniture name must reflect the true attributes and comply with the corresponding national or industrial standards. The instructions for use must explain the relevant requirements and indicators of the state, and give explanations on the control indicators such as the materials used in the furniture and the toxic substances or radioactivity actually contained in the paint. If the merchant is unable to provide instructions on the use of the product, the merchant should be required to note the variety and location of the wood used in the sales contract. The consumer must have the initiative to sign the contract when customizing the furniture, and refine the style of the furniture and the plate in the contract. Material, specifications, quality of hardware, etc. In addition, before signing the contract, consumers should be able to check the relevant information, or find friends who are familiar with the situation to ensure that they are aware of their own, even if the quality of the furniture in the future can better protect their legitimate rights and interests.
Hydraulic Valve
A hydraulic valve is a device used to control the flow and pressure of hydraulic fluid in a hydraulic system. It is typically made up of a valve body, which contains the necessary ports and passages for fluid flow, and a valve spool or poppet, which is responsible for regulating the flow of fluid.
Hydraulic valves can be classified into various types based on their function and design. Some common types include:
1. Directional control valves: These valves control the direction of fluid flow in a hydraulic system. They typically have multiple ports and can be used to control the movement of hydraulic cylinders or motors.
2. Pressure control valves: These valves regulate the pressure of the hydraulic fluid in a system. They can be used to maintain a specific pressure level or limit the maximum pressure.
3. Flow control valves: These valves control the rate of fluid flow in a hydraulic system. They can be used to adjust the speed of hydraulic cylinders or control the flow to different actuators.
4. Check valves: These valves allow fluid flow in one direction while preventing it from flowing back in the opposite direction. They are commonly used to maintain pressure in hydraulic systems or prevent backflow.
Hydraulic valves are essential components in hydraulic systems, as they enable precise control and efficient operation. They are commonly used in various industries, including manufacturing, construction, agriculture, and automotive.
