How to install components in positive pressure type explosion-proof power distribution cabinet

Positive pressure type explosion-proof power distribution cabinet can also be called positive pressure type explosion-proof cabinet, explosion-proof fume hood, explosion-proof compensation cabinet and so on. Explosion-proof positive pressure cabinets are widely used in petrochemical, offshore drilling platform metallurgy, medicine, light industry, textile, food, bioengineering, aerospace engineering and military facilities.
With the development of society, the use of explosion-proof positive pressure cabinets is more and more extensive, so how to install the components in the explosion-proof positive pressure cabinet?
First, the positive pressure type explosion-proof power distribution cabinet can be installed according to user requirements of various common monitoring instruments, analytical instruments, display instruments, micro-computer touch screens and ordinary electrical components, and the user-installed electrical components are basically not restricted.
Second, since the components of the power distribution system in the cabinet are installed by the user, the user must install and debug in the safety zone.
3. Do not remove the electrical components on the panel to avoid affecting the airtight performance of the cabinet.
4. The low-pressure interlocking contactor is installed in the positive pressure chamber. The user should interlock the power supply of the main power distribution system through the low-voltage interlocking contactor, so that when the pressure of the positive pressure chamber is too low, the main power distribution power supply is cut off by the contactor. .
5. When the user is wiring, please pay attention to the sealing performance of each incoming and outgoing cable, and use the explosion-proof glue for proper sealing treatment according to the tightness of each power.
6. After the user has finished wiring the wiring, the user must ensure the sealing performance.
7. The cabinet must be installed with the required grounding wire connected to the special grounding screw.

Curing Agent

Curing agents, also known as hardeners, are essential components of many polymer systems, including Epoxy Resins. Curing agents react with the epoxy resin to form a three-dimensional crosslinked network, resulting in a cured polymer with improved mechanical properties, chemical resistance, and thermal stability.

There are several types of curing agents, each with its own unique properties and applications. The most common type is amine-based curing agents, which react with the epoxy functional group to form a secondary amine and an alcohol. This reaction is exothermic and can be accelerated by heat, making it ideal for high-temperature applications.

Another type of curing agent is anhydride-based, which react with the epoxy group to form a cyclic acid anhydride and a hydroxyl group. These curing agents are typically used in applications where water resistance is critical, such as marine coatings and adhesives.

Other types of curing agents include phenolic, acid, and catalytic curing agents. Phenolic curing agents are used in high-temperature applications, while acid curing agents are used in low-temperature applications. Catalytic curing agents are used to accelerate the curing process and are typically used in combination with other curing agents.

The choice of curing agent depends on the specific application requirements, such as cure time, cure temperature, and final properties of the cured polymer. It is important to choose the correct curing agent to ensure that the final product meets the desired specifications.

In summary, curing agents are essential components of many polymer systems, including epoxy resins, and play a critical role in improving the mechanical, chemical, and thermal properties of the cured polymer. The choice of curing agent depends on the specific application requirements and must be carefully considered to ensure the final product meets the desired specifications.
