Problems solved by technology

[0002] At present, there are two main methods of manufacturing plastic (PE) detonators at home and abroad. The first one is the most common domestic single-extrusion single-layer ordinary detonator manufacturing technology. The advantages are: low cost and mature process methods; The disadvantages are: low tensile strength, soft nonel, and inconvenient construction. The second type is the double-layer nonel production technology represented by foreign imports, and this double-layer nonel production technology is divided into two categories. One is secondary processing, artificial large pipe sleeve small pipe to achieve reinforcement and change the material of the outer large pipe to achieve high-strength nonel or functional products, such as: oil-resistant, temperature-resistant, high-strength type, and improve the nonel at the same time Rigid, easy construction
The other is that one extruder first extrudes the small pipe, and then through the tractor through the second extruder, the surface of the small pipe is coated and enhanced. This kind of double-layer nonel production equipment manufacturing technology Disadvantages are high product cost, expensive nonel equipment, and long process route
