Ultraviolet Irradiation Crosslinking Equipment
Application of UV-light irradiation cross-linked equipment
The UV-light irradiation cross-linking process uses UV-light as the irradiation source, extrudes and coats the mixed photo-crosslinking polyolefin compound on the conductor wire core, and then immediately enters the special irradiation equipment for fused photo-crosslinking. The insulated wire core after light irradiation cross-linking can be produced into photo-crosslinking polyolefin insulated wire and cable products through cooling treatment at different temperatures and other subsequent processing.
UV-light irradiation cross-linking method needs to be slightly modified only on the original normal extrusion production line. The upper traction, irradiation box and electric control cabinet with a small floor area can meet the operating requirements and produce UV-light irradiation cross-linked polyethylene wire and cable products. The addition of upper traction enables the conductor wire core to maintain a certain tension. In the running process, it shall be always in the center of irradiation box to ensure the best irradiation effect. The irradiation box uses a reflective focused UV light source that is uniformly configured and specially designed, and the electrical control system will ensure that the UV-light intensity and the irradiation temperature in the center of the irradiation box are in the optimum operating conditions. In addition, the efficient photo-initiation system rapidly induces cross-linking reaction of polyolefin under the UV-light irradiation, so that the irradiation equipment can reach a continuous production speed of dozens of meters per minute, and gradually cools at hot, warm and cold temperatures to ensure the stability of three-dimensional cross-linked netlike structure.

Vernier Caliper Vernier caliper is a measuring tool for measuring length, inner and outer diameters and depth. It consists of two parts, that is, the main scale and the vernier attached to the main scale. The vernier is an integral whole if looking from the back. The main scale is generally measured in millimeter, while the vernier has 10, 20, or 50 subdivisions. According to different subdivisions, the vernier caliper can be classified into vernier caliper with ten subdivisions, vernier caliper with twenty subdivisions and vernier caliper with fifty subdivisions. There are two movable measuring jaws on the main scale and vernier of the vernier caliper, that is, the internal and external measuring jaws. The internal measuring jaw is usually used to measure inner diameter while the external measuring jaw is usually used to measure length and outer diameter.
