There are certain differences between outdoor APs and indoor APs. If outdoor APs need to be used to build an outdoor wireless network, how to choose the right one? Tianbo Technology briefly summarizes the following 4 aspects.
1. Can adapt to changing temperature
Because it is used outdoors, and the outdoor environment is changeable, the temperature difference between our south and north is also very large. The temperature in the south can reach above 50 ℃ in summer, and the temperature in the north can reach below minus 30 ℃. In addition, the temperature in the same place in summer and winter is also very different, so the outdoor AP's ability to adapt to temperature is critical. You can't buy it back and use it for a few days.
In order to adapt to the environment, the components of the outdoor AP have higher quality, and the shape and structure must be excellent. Generally, lightning protection design will be done internally, with lightning protection index above 4kv. The exterior is to be fully sealed, and the quality of the outer shell used is very high.
2. Waterproof and dustproof
In addition to the variable temperature outside, and the possibility of rain at any time, waterproof ability is very important. The waterproof ability is related to the design of the shell, and it must be fully sealed. The design of each screw and each groove must be very careful, because the screw design is not good, it may leak, and the groove design is not good, which may cause Water accumulation may cause water seepage over time.
In addition to this, it must also be dustproof. Year after year and four seasons alternate, the AP can not avoid the invasion of dust for a long time. This depends on the material of the housing. The general waterproof and dustproof requirements are around IP66. When evaluating outdoor APs on site, you only need to soak the AP to be purchased for 10 minutes in water, and then use it after power-on to know how the AP is waterproof and dustproof.
If the appearance is made of metal, it also depends on its anti-rust. Generally, the AP is coated with a layer of corrosion and anti-rust film, so as to ensure that the outdoor AP can work stably in the humid environment such as the seaside for a long time. That is to say, ordinary bare, or unprotected aluminum alloy and other metal shells are not capable of such a long-term environment.
3. Port lightning protection
To be precise, it should be port protection capability. Outdoor AP is exposed to wind and rain for a long time, its port protection ability is very important. For example, when using the electrical port, the unused optical port needs to be sealed with a plug.
In addition, the biggest risk faced by a port is voltage surges, which we usually call port lightning protection. For port lightning protection, many people mistakenly believe that it is to prevent lightning strikes. In fact, the prevention of "direct lightning strike" generally depends on the lightning rod. If the AP is really struck by lightning, it is useless to protect it. The port protection is against "induction lightning". Under lightning weather, the voltage surge will be relatively large. Inside the various ports of the AP, the chip is relatively fragile. If not protected, the chip may be burned.
4. Power index
The power of outdoor APs is generally higher than that of indoors, basically above 500mw, and some even reach 1W. The greater the power, the farther the signal is transmitted and the stronger the signal.
When choosing an outdoor AP, be sure to understand these important information in detail. We should pay attention to the design and workmanship of the outdoor AP, the shape of the casing, and the product sealing, as well as its chips, lightning protection, and power. Tianbo outdoor AP not only can withstand harsh environmental tests, but also has the characteristics of high speed, safety, simple installation and convenient use, making it an ideal choice for outdoor wifi applications.

Acryl Curing Agent

Acrylic curing agents are a type of crosslinking agent used in the production of high-performance coatings and adhesives. Acrylic curing agents are typically used to cure Epoxy Resins, improving their mechanical properties, chemical resistance, and thermal stability.


Acrylic curing agents react with the epoxy functional group to form a thermosetting coating or adhesive. This reaction is exothermic and can be accelerated by heat, making it ideal for high-temperature applications. Once cured, the acrylic modified epoxy resin offers excellent resistance to weathering, UV light, and chemicals.


Acrylic curing agents offer several advantages over other types of curing agents. They are low in viscosity, which makes them easy to handle and mix with epoxy resins. They also have excellent adhesion to a wide range of substrates, including metals, plastics, and composites.


Acrylic curing agents are available in a range of grades, each with its own unique properties and applications. Some grades offer improved toughness and flexibility, while others offer improved chemical resistance or high-temperature performance. The choice of acrylic Curing Agent depends on the specific application requirements, such as cure time, cure temperature, and final properties of the cured epoxy resin.


Acrylic curing agents are commonly used in applications where high-performance coatings or adhesives are required, such as automotive, aerospace, and marine applications. They are also used in the production of electrical and electronic components, where their excellent electrical properties make them an ideal choice.


In summary, acrylic curing agents are a type of crosslinking agent used to cure epoxy resins in the production of high-performance coatings and adhesives. They offer several advantages over other types of curing agents, including low viscosity and excellent adhesion to a wide range of substrates. The choice of acrylic curing agent depends on the specific application requirements, and they are commonly used in applications that require high-performance coatings or adhesives, such as automotive, aerospace, and marine applications.
