In the past, we have introduced a lot of different aspects of heat shrinkable tubes, in order to let our customers better understand and understand the heat shrinkable tube, but in essence, once the principle of heat shrinkable tube is mentioned Such professional problems, in fact, many customers, even long-term customers who use fixed heat shrink tubes, are not particularly clear.
When it comes to the principle of heat-shrinkable tube, it is simple and simple. It is difficult and difficult to say. To put it simply, the process of shrinking after heat-shrinking the tube is completed. It is clear to everyone that it is necessary to heat the heat-shrinkable tube. In order to shrink, referring to the principle of heat shrinkable tube, the most important thing is to explain from the aspect that heat shrinkable tube heating can shrink.
This irradiation process will use an electron accelerator. This electron accelerator, as everyone knows, is not available to all companies. The heat shrinkable tube principle relies on this machine to function. The heat shrinkable tube is in the first place. After the extrusion of the production process, it is sent to a third party for irradiation. It requires great attention during irradiation. The irradiation dose plays a decisive role in the heat shrinkable tube principle. After the heat shrinkable tube is extruded Extrusion molding, showing flattened tubular shape, the irradiation is mainly through the electronic accelerator, the internal structure of the heat-shrinkable tube changes, cross-linking, changing the molecular arrangement, has a "memory" function, popularly speaking, is to make heat shrink The tube can be retracted. Strictly speaking, the heat-shrinkable tube does not have the principle of heat-shrinkable tube after extrusion. After changing the molecular structure, the expansion process is performed. At this time, the heat-shrinkable tube diameter is enlarged and reheated. When the heat shrinks, the intermediate retraction process is the heat shrinkable tube principle, which benefits from the external processing of the irradiation. In the irradiation process, the irradiation dose is also an aspect that we need to strictly control. The low irradiation dose or the high irradiation dose will affect the heat shrinkable tube. Therefore, after completing the irradiation process and before the expansion process, Strict inspections will also be conducted.
