Wooden furniture, including Huanghuali, red sandalwood, mahogany, wenge, rosewood, and more, can last for generations with proper care. Maintenance tips include:
First, traditional hardwood furniture typically doesn’t have a painted surface, only being polished with wax. Modern pieces often come with a lacquer or varnish coating, requiring different maintenance approaches.
Second, wooden furniture contains moisture. High humidity may cause swelling, while low humidity leads to shrinking. Always ensure your furniture is stored in a stable environment—away from extreme heat sources like stoves or overly damp basements to prevent mold and cracking.
Third, if your home is on the ground floor, place furniture on appropriate padding if the floor is damp to avoid corrosion of the legs. Moving furniture should be done gently to avoid damaging its structure—lift tables carefully by their surfaces rather than handles, and cabinets should ideally have doors removed before lifting.
Fourth, avoid placing excessively heavy items, like TVs or aquariums, on furniture surfaces for long periods, as this can lead to warping. Non-breathable materials like plastic sheets shouldn’t be used on tabletops either.
Fifth, uneven floors over time can distort furniture shapes. To fix this, use small wooden shims to level them out.
Sixth, avoid using rough cloths when cleaning hardwood furniture. Instead, opt for soft cotton cloths dipped in furniture wax or walnut oil, gently rubbing along the grain.
Seventh, protect surfaces from scratches caused by hard objects. Decorative items like bronze statues should be placed carefully, and soft cloths are recommended for cleaning.
Eighth, keep furniture away from large southern-facing windows to avoid prolonged sun exposure, which can dry out and fade the wood.
Ninth, avoid placing hot items like mugs directly on furniture surfaces, as they can leave unsightly marks. Similarly, colored liquids like ink should never be spilled on tables.
Electric valve is a device that drives the valve to open and close by electric motor. It is widely used in various industrial and civil fields, such as metallurgy, chemical industry, petroleum, natural gas, heating, ventilation and air conditioning, automatic control, etc. The following are some application scenarios of electric valves:
1. Fluid control in industrial production: electric valve can be used to control the flow, pressure and temperature of liquid, gas and steam to meet the needs of industrial production.
2. Oil and natural gas industry: electric valves can be used in oil and natural gas exploitation, processing, transmission and storage to control flow and pressure and ensure production safety and efficiency.
3. Chemical industry: electric valve can be used for fluid control in chemical production, such as acid-base solution, gas and liquid reactant control, to ensure the safety and efficiency of production.
4. Heating, ventilation and air conditioning system: the electric valve can be used to control the water flow, air flow and temperature in the heating, ventilation and air conditioning system to meet the requirements of the indoor environment.
5. Automatic control system: electric valve can be used with automatic control system to realize automatic control and adjustment of fluid flow, pressure, temperature and other parameters.
In short, electric valves are widely used in industrial and civil fields, which can improve production efficiency, ensure product quality and improve production safety.
