This' prevention 'refers to the three defenses.

1、 Moisture proof and waterproof

In the field, different from the indoor stable environment, due to the influence of various weather reasons such as heavy rain and rainstorm, the field power supply is required to have the most basic moisture-proof and waterproof functions in order to make the LED light-emitting characters of the light box work in the rain.

This function is usually achieved through the use of three proof agents.

Three proof agents are materials prepared using nano organic silicon or organic fluorine as the main raw materials through emulsification and other processes. Our general clothing also uses three proof agents to increase the texture of the clothes. In identifying professions, the quality of the three proof agent directly determines the rainproof effect of the rainproof power supply.

The price of three proof agents commonly used by brands in the market is usually 80 yuan per kilogram, while slightly better ones from Taiwan are priced at 85 yuan per kilogram. The rainproof power supply, which costs around 20 yuan, uses the lowest priced three proof agent, only 15 yuan per kilogram, while the best imported three proof agent costs as high as 200-300 yuan per kilogram. This price can be said to be one of the important reasons for the price difference of rainproof power supplies.

2、 Dust prevention

Although dust and sand are not as visible to the naked eye as rainwater, they are constantly present in nature and have a significant impact on outdoor power supplies. They can easily corrode internal components of the power supply, leading to power damage and reduced lifespan.

Like moisture and water resistance, dust prevention is also achieved through the use of three proofing agents.

3、 Salt spray prevention

Many people may not notice this.

After conducting user sampling surveys in coastal areas such as Hainan, Shenzhen, and Fujian, the identification circle obtained the following results:

The damage rate of outdoor rainproof power sources in these coastal areas is much higher than in other inland areas, and the average lifespan is also much shorter.

Taking the mid-range price rainproof power supply in the market as an example, its damage rate after one and a half years of use in other regions is about 2%. The damage rate in coastal and typhoon prone areas such as Shenzhen has increased to 10%, while in the Hainan region, the general rainproof power supply can even last for less than three months.

This is the terrifying aspect of salt spray. Especially in areas surrounded by the sea, the concentration of salt spray in the air is very high, which can quickly corrode the power lines and cause huge damage to the power supply body.

This is something that even ordinary and expensive three proof agents cannot completely isolate

So many people would suggest choosing waterproof power supplies for these areas. Waterproof power supplies differ from rainproof power supplies in that their three proof function is not achieved through the use of three proof agents, but through a fully glued method. They are fully covered with glue and completely sealed to achieve the best waterproof effect. Water cannot enter, and of course, salt spray cannot do anything with them.
