Silicone Rubber Heater Introduction

The tubular electric heating element is composed of a metal tube, a spiral resistance wire and crystalline magnesium powder, with good thermal conductivity and good insulation. The battery energy storage heater is very thin, light and flexible. With this heater, you can transfer heat to any desired place, improve heat transfer, accelerate heating and reduce power requirements during processing. The 3D printer heating sheet uses a layered stacking method to produce a three-dimensional model. Its operation process is similar to that of a traditional printer, except that a traditional printer prints ink on paper to form a two-dimensional plane drawing, while a 3D printer stacks liquid photosensitive resin materials, molten plastic filaments, gypsum powder and other materials by spraying a binder or extruding to achieve layered stacking to form a three-dimensional entity. Silicone rubber waterproof heating pad is a thin sheet that heats up when powered on. The core uses nickel-chromium wire or nickel-chromium foil etched into a certain shape, so it has high reliability. It is a common printing on insulating materials with any slurry such as graphite slurry and resistance slurry. It is suitable for heating air, oil, water, chemical media, hot pressing molds, molten salts, alkalis, and low melting point alloys. It has the characteristics of high thermal efficiency, long service life, high mechanical strength, easy installation, safety and reliability.

The figure below shows the structure of the tubular heating element. The tubular heating element can be processed into U-shaped, corrugated, spiral, straight rod, etc. The cross-section of the component can be divided into circular, elliptical, rectangular, triangular and other categories.

The component adopts single-end or double-end connection, with 1 to 3 connecting rods at each end.

Three-phase circuit connection method of silicone rubber heater

In a 380-volt three-phase four-wire circuit, the voltage between any two hot wires is 380 volts, and a voltage of 220 volts can be formed between any hot wire and the neutral wire.

Use of silicone rubber heaters

Sry2 and sry3 tubular lithium battery heaters are used to heat oil in open or closed oil tanks. Sry4 tubular lithium battery heaters are used to heat flowing or circulating oil.

Use, maintenance, precautions and working principle

Maintenance and safety precautions during use

1. The "b" dimension in the dimensional drawing must be completely immersed in the oil to avoid burning of components. The heated oil should be non-corrosive.

2. The working liquid level of SRY3 must be lower than the fastener and higher than the dimension line "B".

3. When melting solid oils such as asphalt and paraffin, the voltage should be reduced first and then increased to the rated voltage after melting. In order to prevent power concentration and reduce the service life of components.

4. If carbon is found on the surface of a pipe, it must be removed before use to avoid reducing work efficiency or even burning components.

5. The components should be stored in a dry place. If the insulation resistance drops below 1 megohm due to long-term storage, it can be dried in an oven at about 200°C for a few hours (or passed through the component at low voltage for a few hours) to restore the insulation resistance.

Basic working principle of silicone rubber performance heater

The high-temperature resistance wire is evenly distributed in the high-temperature resistant stainless steel seamless pipe, and the gap is densely filled with crystalline magnesium oxide powder with good thermal conductivity and insulation.
