                     Working principle and product details  

                                  1、 Product main image

The ignition electrode (ceramic ignition needle) is mainly assembled from high temperature resistant alumina ceramics and resistant high temperature alloys, high temperature and high voltage wires, terminals, etc. It has the advantages of sensitive and reliable ignition, high temperature and oxidation resistance, and is widely used in liquefaction Intermittent ignition of LPG gas appliances (stove, water heater, barbecue stove, burner, gas lamp, heating stove, etc.).

                                       2、Ceramic part

Ceramic length:55.4mm   Ceramic diameter:6.5mm

The 95 alumina piece is formed by hot pressure casting slurry and sintered at a high temperature of 1500℃. It has the following advantages:

1. High mechanical strength and wear resistance;

2. Strong chemical resistance to acid and alkali.

3. Good electrical insulation performance at room temperature and high temperature.

4.Small mechanical strength loss under high temperature

                                        3、Electrode part

Electrode material:Ocr25Al5  Cr20Ni80 

Electrode length:55; Electrode diameter:1.6mm

Iron-chromium-aluminum resistance electric heating alloy has the characteristics of high resistivity, low temperature coefficient of resistance and high operating temperature;

Resistance electric heating alloy, this kind of alloy has stable structure, stable electrical and physical properties, good high temperature mechanical properties, good cold deformation plasticity, good weldability, and will not produce brittle fracture after long-term use. It is mostly used in the manufacture of household appliances and heating elements whose working temperature is below 1000℃, with long service life.

                                            4、Wire

Wire material:  Alloy with glass fiber protection cover

Advantages of glass fiber: good insulation, strong heat resistance, good corrosion resistance and high mechanical strength.

(1) High tensile strength and low elongation (3%).

(2) High elastic coefficient and good rigidity.

(3) The elongation is large within the elastic limit and the tensile strength is high, so the impact energy is large.

(4) It is an inorganic fiber with non-combustibility and good chemical resistance.

(5) Low water absorption.

(6) Good scale stability and heat resistance.

(7) Not easy to burn, it can be melted into glass beads at high temperature
