Therefore, the quasi-explosion rate of the electronic detonator product, i.e., the product quality, is very important.

There are three general ways to protect the cap of an electronic detonator, namely, the bridge wire is added with a cap fixing bowl, cap sleeve silica gel and a cap sleeve heat shrink tube. The three modes are good and bad, the defect of the fixed bowl needs to use sensitive medicament, and manual dispensing is adopted, otherwise, air bubbles are easy to generate, so that the safety, the efficiency, the labor intensity, the accurate burning rate of the medicine head and the like are greatly influenced, the medicine head sleeve of the electronic chip module becomes the main stream, the protection effect is not greatly different when the medicine head sleeve heat-shrinkable tube is compared with the protection effect when the medicine head sleeve heat-shrinkable tube is sleeved with silica gel, and the wrapping effect of the heat-shrinkable tube is better.
