Encapsulation type electrical equipment explosion-proof measures - Solutions - Huaqiang Electronic Network

Explosion-proof measures taken by encapsulated electrical equipment are the use of potting agents. Therefore, it is very important to fully understand the performance of the potting agent, the potting process and related technical requirements. The potting agent is a potting material with certain chemical, thermal, electrical and mechanical resistance. It has thermosetting, thermoplastic and room temperature curing properties. A commonly used potting agent is an epoxy resin, the solvent of which is ethylenediamine.

Pouring is divided into two types: embedding and canning due to the different processes used. The so-called embedding means that the dissolved potting agent is cast in the model, and the encapsulated part is completely buried in the potting agent, and the mold shell is removed after the potting agent is solidified. The so-called can sealing means that the dissolved potting agent is injected into the mold, and the potted component is completely buried in the potting agent, and the mold casing remains after the potting agent is solidified. The canned model casing is made of a metal material and is also made of an insulating material which must be made of an inorganic material.
