Explosion-proof cameras can be used in many energy and chemical industries including petrochemicals, petroleum, etc. due to their excellent performance and wide adaptability. However, each industry has its own particularity and needs to be specially targeted for explosion protection, so that it can do more with less. Before installing the explosion-proof camera, check the following.
1.Whether the explosion-proof monitoring equipment is selected and classified according to the regional classification, whether it is suitable for the protection of the ambient gas classification; whether the temperature level of the explosion-proof monitoring and power control equipment is suitable for the spontaneous combustion of the surrounding flammable gas; qualified explosion-proof electrical explosion-proof equipment should be marked: manufacturer name , certification unit, certification number, explosion-proof structure applicable gas group, temperature rating.
2. Whether the line marking data of the explosion-proof camera equipment is complete, whether the camera housing shield and the function are damaged, and whether the monitoring equipment protection cover and the sealing gasket can be completely sealed.
3. Screws, cable interface equipment (direct or indirect) and spacing components are of the correct model, the pipeline screws or joints can not be loose, the joints are clean and damage-free, monitoring cable joints must be explosion-proof joints and explosion-proof certification mark.
4. If there is a gasket on the pressure-explosion-proof equipment interface, it should be confirmed whether it is purely waterproof.
5. Field signal transmission Explosion-proof box The gasket of the electrical equipment shell is normal. Is the screw locked to the position?
6. Explosion-proof monitoring equipment sealing gasket should be silicone material is not easy to aging, difficult to change the material.
7. Explosion-proof fillers should be used at the joints of the explosion-proof box and the camera to prevent electrical sparking inside the equipment.
8. Is the installation of monitoring equipment and explosion-proof enclosures properly grounded as required?
9. Does the explosion-proof explosion-proof box have a safety lock or must be opened with a special tool?
In order to ensure safety, these options should be checked one by one and confirmed, so as to introduce the occurrence of blow-by leakage after the installation of the explosion-proof camera to prevent the above situation from making mistakes.
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.
