In fact, silicone heating line is often contacted, but can not touch the core, silicone heating line this word, everyone may sound a little strange, but electric blanket must be known to everyone, below I will introduce in detail the use and use of silicone heating line.
Silicone heating wire picture
First, the use of silica gel heating wire and its use method
1, silica gel heating line, temperature resistance limit 200 °C, divided into, flame retardant, semi-flame retardant, and non-flame retardant, three levels, is a kind of energized heater products, usually heating temperature is between 30 °C-170 °C, can be manually controlled, control measures are divided into, temperature limit control, temperature sensing control, constant temperature control, three methods.
2, temperature limit control, is one of the most common and common methods, fast and easy to use, simple and fast, easy to control, the most important thing is low cost, just cut the silicone heating line to a certain length.
3. The hot wire is connected to the wire at one end, and the other end is connected, one of the two wires on the temperature protector, and the second of the temperature protector wire is connected to the wire, and finally insulated with a casing at the joint part, and finally the protector is close to the heating part to achieve temperature control.
4, control the standard of temperature, depending on the quality of the temperature protector, the general operating temperature is ±10 °C, the calibration temperature is ±20 °C, the output power design of the hot wire is generally 15W/M, heating within 80 °C, the output power design is not easy to be too large, otherwise it is easy to cause frequent work of the temperature protector, resulting in premature damage of the protector, and then cause the contact point of the protector to break or stick, causing no heating or fire and other phenomena.
5, temperature control, this form of temperature control is more complex, the cost is also very high, the first thing to do is to develop an IC control board circuit, followed by matching thermistors, after doing the above two items, it is easier to control, one is to put the thermistor close to the heating part, thermistor is by the temperature to collect heating signals, and for different temperatures, send different signals to the IC control board.
6. For example, the IC board preliminary setting temperature is 70 °C, when the heating temperature of the hot wire reaches 70 °C, the thermistor will send a signal to the IC board, after the IC board receives the signal, it will automatically cut off the power supply of the hot wire, then the hot wire will stop heating, when the temperature is lower than 62 °C, the IC will provide electricity heating, and the back and forth circulation will form a heating and temperature control mode.
7, constant temperature control, is a kind of simplest method, but also the most difficult to control and the most difficult to operate a method, the current temperature control, accounting for 65% of the market, temperature control, accounting for 30% of the market, constant temperature control, accounting for 5% of the market, its difficult to control the degree of the market to see the proportion of the market to know.
8, constant temperature control, is only in the case of fixed voltage can be achieved, for example, constant temperature 50 °C, the first step is to find a fixed voltage, commonly used for 12V, 24, 110, 220, etc.
9, the second step is to design the output power, constant temperature is not easy to design the output power too large, otherwise it is easy to exceed the temperature standard, first design an output power as the center point, such as 30W, and then power test, the test time is 8H, 8H after watching the temperature data, if the temperature is super high, the output power in the second reduction test, so step by step cycle test, until the temperature is satisfactory.
