01 Research on the civil explosives industry, electronic detonators are on the rise
In the field of infrastructure construction that my country focuses on supporting development, the civil explosives industry is a relatively niche but very important industry. In the “14th Five-Year Plan”, the country vigorously promotes the replacement of industrial detonators with electronic detonators and continues to strengthen incentives and guidance. Electronic detonators are also called digital electronic detonators, digital detonators or industrial digital electronic detonators, that is, electric detonators that use electronic control modules to control the detonation process.
The electronic detonator has a built-in electronic detonator control module, which has the function of controlling the detonation delay time and energy, and can communicate with the detonation controller and other external control devices.
02 The core key components in electronic detonators – capacitors
Among them, the energy storage capacitor is an extremely important component. It absorbs the energy released by the energy storage capacitor in a very short time through the control module, and then the detonating agent in the detonator can complete the detonation. In the process, a sense agent is generally used to cooperate to greatly improve the safety of electronic detonators, but its detonation requires a large amount of energy, which is a challenge for energy storage capacitors.
At present, the mainstream types of energy storage capacitors are mainly liquid aluminum electrolytic capacitors and polymer tantalum capacitors. Polymer tantalum capacitors are insufficient in withstand voltage and overcurrent capabilities, which limits their use with sense agents. Because tantalum capacitors will cause electronic detonators to fail and cannot be detonated, and after failure, open flames are easily generated, affecting product reliability. This leads to electronic detonators using tantalum capacitors being weak in safety, and their sales channels are limited. Most of them rely on imports, and the supply and delivery period are unstable. The delivery cycle is sometimes as long as half a year.
For this reason, how to improve the safety and stability of energy storage capacitors has become the key point in optimizing electronic detonators, and we need to solve the problem.
03 YMIN helps detonators meet new market demands and challenges
YMIN’s L3M series of liquid aluminum electrolytic capacitors for detonators can solve the above problems. Taking this L3M 25V 100uf 4*11 product as an example, the specific parameters are body height ≤11, actual capacitance ≥100uf (25° environment), and ESR value ≤2.0Ω.
As the main brand of domestic capacitors, YMIN liquid aluminum electrolytic capacitors have the advantages of large capacitance, small leakage current, low ESR, high reliability, small size, and good product consistency under the same requirements as imported tantalum capacitors. The products have obtained IATF16949 (international standard for the automotive industry) and national military standard quality management system certification. It can effectively guarantee the safety performance of electronic detonators, prevent the failure of electronic detonators, meet the cost advantages of the whole machine, and at the same time achieve low cost and meet the needs of supply and delivery time.
From the perspective of market supply, YMIN’s L3M series of aluminum electrolytic capacitors have been used in the electronic detonator market in large quantities. Compared with tantalum capacitors, liquid aluminum electrolytic capacitors have stable production, short supply cycles, and more obvious price advantages. They have been unanimously recognized by customers for their extremely small size and excellent low-temperature characteristics!
