Polymer moisture-proof sealing agent for the ring main unit of Southern Power Grid State Grid

Polymer moisture-proof sealing agent for the ring main unit of Southern Power Grid State GridScope of application:
1. Various electrical equipment such as switchgear, control panels, power boxes, etc. pass through holes in floor slabs or partition walls for incoming and outgoing lines; 2. Sealing of cable conduit openings: Cable conduit openings leading out of cable chambers, cables, cable trenches, etc.:
3. Sealing of elevator shafts, air conditioning systems, and other pipeline shafts in high-rise buildings.

PLC control cabinet polymer moisture-proof sealing agentProduct Introduction: This product appears as a liquid before vulcanization and is divided intoA. B consists of two components with good fluidity. When used on site, they are mixed and stirred evenly in a 10:1 weight ratio. They are applied to the sealing surface and flow towards the dead corners of various structural gaps. They can achieve automatic leveling and are tightly integrated with the box structure and cables; The operation time of AB mixed reaction is generally 30-60 minutes, which can achieve automatic bubble discharge. After 1-2 hours of vulcanization, a mirror sealing layer is formed with good flexibility. When adding cables or conducting secondary construction maintenance in the later stage, a manual knife can be used to cut open the sealing layer hole. After the secondary construction is completed, the opening part can be sealed with moisture-proof sealing agent.

Construction process of moisture-proof sealing agent:

1. First, make a budget for material usage:

The density of polymer moisture-proof sealing agent isBetween 1.15-1.18, the thickness is generally 0.8-1 cm, and the usage range per square meter is around 11KG.

2. Perform leak sealing work on the sealing surface of the box:

To avoid the leakage of sealing agent from the leak, resulting in waste; Generally, silver electric tape or fireproof mud is used to seal the areas with leaks, and then excess lines are neatly arranged with tape;

3. Construction:

Translate into EnglishMix agent A with a flashlight for 20-30 seconds to prevent settling, then add agent B to agent A and mix for about 60 seconds. Apply to the target area. The regular operating time for the sealing agent is 30-40 minutes (adjustable), and it can automatically level; If the box area is large, a scraper or brush can also be used to accelerate the spreading speed of the sealing agent.

4、 等待硫化：

Waiting for the sealing agent to undergo vulcanization molding, the initial vulcanization molding time is1.5-2 hours, * vulcanization molding time is 24 hours.

PS: During construction, attention should be paid to sealing off leaks to avoid missing sealing agent materials and causing waste. Due to the influence of environmental temperature and humidity on the operation time of the sealing agent, it is recommended to conduct a small test before use. If the operation time needs to be extended, the proportion of B agent can be adjusted to 10:0.8, not lower than 0.7, to avoid affecting the vulcanization effect.
