Waterproof cover seals
The waterproof cover is usually equipped with a rubber seal to provide reliable waterproof performance. These rubber seals are located between the waterproof cover and the lighting device housing, ensuring that the inside of the device remains dry and waterproof in wet environments.
Advantages
- Watertightness and airtightness: The waterproof cover seals have excellent watertightness and airtightness to ensure their waterproof effect.
- Weather resistance: Waterproof sealing materials usually have good heat resistance and cold resistance, so that the waterproof cover seal can maintain stable performance under various environmental conditions.
- Adhesion: The waterproof sealing material will be firmly bonded to the surface of the joint without gaps to ensure reliable watertightness and airtightness.
- Durability: A good waterproof cover seals have good durability and can maintain its sealing effect during long-term use.
On high bay lights used for industrial plant lighting, it is very important to choose the right rubber material for the waterproof cover seal to ensure the sealing and durability of the lamp in humid or harsh environments. The following are several suitable rubber materials
| Rubber material | Oil resistance | Chemical resistance | Aging resistance | Weather resistance | Heat resistance | Low temperature resistance | Operating temperature range (℃) | Applicable scenarios |
| Nitrile rubber | Excellent | Medium | Medium | Medium | Medium | Medium | -40～100 | General industrial application environment |
| Fluororubber | Excellent | Excellent | Medium | Medium | Excellent | Medium | -20～200 | High temperature and high pressure, corrosive medium environment |
| EPDM rubber | Medium | Medium | Excellent | Excellent | Excellent | Medium | -50～120 | Outdoor, long-term exposure to sunlight environment |
| Silicone rubber | Medium | Medium | Excellent | Excellent | Excellent | Excellent | -70～260 | Extreme temperature change environment |
- Nitrile rubber (NBR)
If the high bay light is installed in an environment containing oil or requiring wear resistance, nitrile rubber is a good choice.
- Fluororubber (FKM)
Applicable scenarios: Especially suitable for use in chemical plants or industrial plants that need to resist strong acids, alkalis, and high temperatures.
- Ethylene propylene diene monomer (EPDM)
Applicable scenarios: Suitable for outdoor or industrial plants that need to be exposed to sunlight for a long time, and can resist the erosion of ultraviolet rays and ozone.
- Silicone rubber (SI)
It has outstanding high temperature resistance, ozone resistance and weather aging resistance, and can maintain its unique use flexibility within the operating temperature range of -70 to 260°C.
Applicable scenarios: If the high bay light needs to be used in an environment with extreme temperature changes, silicone rubber is a suitable choice.
- Choose according to environmental conditions: If the factory environment is humid and the temperature does not change much, you can choose nitrile rubber or EPDM rubber; if the ambient temperature is high and there is a risk of chemical corrosion, fluororubber is a better choice.
- Consider the balance between cost and performance: The cost of nitrile rubber and EPDM rubber is relatively low, but the performance can also meet the needs of most industrial plants; while fluororubber and silicone rubber have better performance, but the cost is also higher, suitable for occasions with higher requirements for sealing performance.
These rubber seals are typically soft, elastic, and durable, effectively resisting the intrusion of moisture, dust, and other contaminants, ensuring the safe operation of the lighting fixture's internal components.
High bay lights for industrial plant lighting: High bay lights are usually installed at higher locations and require regular maintenance. The waterproof cover seal between the back cover and the main body of the lamp can prevent dust and moisture from entering the lamp, reduce dust accumulation inside the lamp and malfunctions caused by moisture, and ensure the sealing of the lamp after maintenance.
