You don’t know the “unspoken rules†of solid wood furniture, so the furniture is more durable
Solid wood furniture is of high grade and expensive, so the maintenance frequency is relatively high, and the cost is not low. How can we make solid wood furniture more durable?
Do expansion joints have to be kept?
I believe that people who have some research on solid wood homes must know the tenon-mortise structure better. It does not need an iron nail, but it can skillfully combine furniture. Expansion joint is to prevent the frame or corner of the furniture from cracking when the wood shrinks or expands due to the influence of the external environment, resulting in the loosening of various furniture components, which cannot be used normally.
How to distinguish "real wood"
The climate and temperature in different regions of my country are different, especially in places with humid climates, solid wood furniture is more susceptible to moisture deformation. Therefore, before the wood is made into furniture, there is generally a drying process. But even so, it is necessary to reserve expansion joints.
The longitudinal shrinkage of the wood is not large, generally no expansion joints are required at both ends. However, there are special cases. Some manufacturers do not keep expansion joints, but not leaving them does not mean not, because manufacturers may prevent the wood from deforming by controlling the dryness of the wood.
How suitable is the expansion joint?
Since most solid wood furniture will retain expansion joints, how much is more important. The width of the expansion joint is generally within 0.3-0.5 cm. If it is too wide, it will be ugly. The width of the expansion joint also needs to be determined according to the actual size of the furniture.
Pneumatic valve is a kind of valve controlled by air pressure, which is widely used in industrial automation control system. Its main applications include the following aspects:
1. Fluid control: pneumatic valve can be used to control the flow and direction of liquid or gas, such as controlling the flow in the pipeline, exhaust gas emission, etc.
2. Pressure control: pneumatic valve can be used to control the pressure of fluid, such as controlling the pressure of compressed air, regulating the pressure in the hydraulic system, etc.
3. Temperature control: pneumatic valve can be used to control the temperature of fluid, such as the temperature of heating or cooling system.
4. Automatic control: pneumatic valve can be linked with sensors, PLC and other equipment to realize automatic control, such as automatic production lines, robots, etc.
5. Safety control: pneumatic valve can be used for safety control, such as controlling emergency stop, preventing overload, etc.
In general, pneumatic valve plays an important role in industrial automation control system, which can improve production efficiency, reduce costs, and ensure safety.
