What should be done if there is electric leakage in silicone rubber heaters?

Many corporate clients consult us by phone or email, asking why there is leakage in the silicone rubber heater they did not purchase. As students, we often encounter such problems. The first thing that comes to mind is whether there is a problem with the flange welding of the heating tube, and secondly, whether there is a quality management problem with the heating tube. The magnesium oxide powder inside the heating tube can also affect the leakage of the heating tube. Next, we will discuss the leakage phenomenon of the heating tube in detail. The oil drum heating belt adopts the soft and bendable characteristics of a silicone heating plate. Metal buckles are riveted on both sides of the heating plate with reserved holes, and spring buckles are used to fasten to the barrel, pipeline, and tank body. Easy and fast installation. It can make the silicone rubber heating plate use the tension of the spring to tightly adhere to the heated part, heating quickly and with high thermal efficiency. The heating element of a 3D printer is stacked layer by layer to create a 3D model. Its operation process is similar to that of a traditional printer, except that traditional printers print ink onto paper to form a two-dimensional flat drawing, while 3D printers use liquid photosensitive resin materials, molten plastic fibers, gypsum powder and other materials to achieve layer by layer stacking and forming a 3D solid through spraying adhesives or extrusion. Silicon rubber heating plate heating element: Wrap nickel alloy heating wire around glass fiber, heating power can reach 2.1W/c ㎡, heating more evenly. Moisture and chemical resistant silicone rubber material provides a longer heater lifespan. Pressure sensitive adhesive can be used to bond flat and smooth workpieces.

All issues related to silicone rubber heater leakage can be traced back to the possible causes of heating pipeline leakage (for reference only):

1. Not properly grounded;

Figure 2. Damage to the insulation layer of the heating tube (this may be a problem with the insulation magnesium powder or joint insulation layer);

3. The silicone rubber heater is burnt out and the cup body is short circuited

4. Improper cleaning caused water to come into contact with the stainless steel heating pipe terminal.

5. Check if the wires in the circuit come off and collide with the cup body;

6. Excessive dirt on power sockets or plugs:

So, what kind of treatment should we take for the leakage of the silicone rubber heater above? The following are:

1. Connect the grounding wire as required and check for correctness;

2. Check if there are such incidents during maintenance and recommend replacement;

3. If the heating tube is damaged, replace it with the same specification;

4. The correct method for developing clean and dry technology to treat stainless steel heating tubes;

5. Check for disconnection and re weld.

6. Proper cleaning and drying treatment:
