Process flow of electric power cold shrink silicone rubber pipe sleeve support strip

In the traditional infusion process, there is no auxiliary equipment, because the medicinal liquid or nutrient solution is stored in a refrigerated or cool place, which is often lower than the body temperature, especially in winter. In this case, the lower temperature of the infusion will lead to faster absorption. slow and cause discomfort to the human body, and the medical silicone heating tube is to add a layer of auxiliary equipment to the infusion pipeline through the principle of electric heating. The carbon fiber heat conduction wire conducts the heat to the silica gel for adjustment and diffusion. The system can adjust the temperature anytime and anywhere until the most comfortable temperature for the human body is between 25°~37°. The whole set of medical silicone heating tube device seems relatively simple, but the production and development process is extremely rigorous.
  Analysis of product components of infusion silicone heating tube device The first major component is silicone, followed by carbon fiber heat conducting wire, thermal probe, and terminal control. Among them, the silicone system is the most complicated. Terminal control can be found in the market for an electric heater. The control system is ready to use. As for carbon fiber thermal wire and thermal probes, there are relatively mature products in the market, so we pay special attention to silica gel. Next, we will introduce some problems that are prone to occur during the production of infusion silica gel heating tube devices and how to solve them. To solve production problems.
Carbon fiber thermal wire (the thinner the better, the premise is to ensure that it will not affect the thermal conductivity)
  Silica gel is divided into various processes and various vulcanization systems. In the production process of the infusion silicone heating tube device, it is necessary to use 2~3 production processes and uniformly use one vulcanization system. First of all, it is necessary to extrude the pipe part in the middle of the infusion silicone heating tube device, because there are four carbon fiber heat conducting wires that will be extruded at the same time as the silica gel, which requires the use of dual-die extrusion, pulling the carbon fiber heat conducting wire while extruding the silicone part The place to pay attention is to mark the outlet direction of the thermal wire, because the silicone needs to wrap the infusion pipe, which is generally open and oval, and the outlet direction of the heat conduction wire should also be square and go out in four directions respectively (the premise is that the outlet direction of the thermal wire needs to be the infusion tube. package), the normal infusion silicone heating tube device has four heat conduction wires, but if the process is mature, it can be increased to 6 heat conduction wires (the number of heat conduction wires increases and the preheating time of silicone shortens, but the difficulty of the production process increases). The advantage of choosing carbon fiber thermal wire is that it is beneficial to the production speed of silicone extrusion. The smaller the size of the thermal wire, the more compact it will be when the silicone is wrapped during the production process, and the aesthetics will rise to a higher level after precision molding.
The carbon fiber heat conduction wire will be integrally formed from the four holes of the silicone heating pipe
  In addition, the skin of the current transformer pipe (silicone wire) of the infusion silicone heating tube device needs to use a platinum vulcanization system. If it is not specifically marked, most silicone wires will be made of a double-two-fourth vulcanization system by default, and because the vulcanization system of the silicone wire and the silicone pipe is inconsistent. As a result, it will not be able to bond effectively when the plugs at both ends are molded in the later stage (in the production of silicone, only products corresponding to the vulcanization system can bond to each other, otherwise other substances are needed to assist). The other is that the conduit for conducting current inside the silicone wire must use a high-temperature-resistant wire (Teflon wire or silicone wire), because the running-in process of the silicone pipe and the silicone wire is run-in by a molding process, and under the premise of running-in, it is necessary It is vulcanized at high temperature, so the silicone wire needs to be resistant to a temperature of 190~220°. The above are the points that need to be paid attention to for the silicone wire.

  Two cavities are reserved in the pipeline of the infusion silicone heating tube device to fill the thermal probe. The main purpose is to monitor the temperature of the pipeline and feed back the data to the terminal control system. Although it is an inconspicuous process here, it is also a step that requires special attention. Heat There is no high temperature resistant probe above 200° on the market, so we need to find a way to insulate the heat and wrap it on the outside of the thermal probe, and the wrapped material must be resistant to a temperature above 200°. The wrapping material we currently use is high temperature resistant insulating silicone tape. The 24-hour self-melting one can effectively insulate the high temperature and avoid the damage of the thermal probe due to the influence of high temperature. The silicone pipe and plug are vulcanized in the molding process and the entire vulcanization process is carried out at a high temperature of 200°. The high temperature resistant silicone tape needs to wrap the entire wire head and wiring part. The entire wiring part of the infusion silicone heating tube device is extremely complicated and all the wiring and connectors (cables and components inside the plug) must be wrapped with self-adhesive silicone tape to operate.
All wires in the silicone wire need to withstand high temperature of 200° (Teflon or silicone skin needs platinum vulcanization, and the whole set of products is unified as platinum vulcanized silicone as shown in the physical picture below). All wires need to be wrapped, and the wrapped material should also be platinum vulcanized and high
