Special ignition wire for oxygen bomb | Special ignition wire for calorimeter | Hebi Tianrui

Special ignition wire for oxygen bomb | Special ignition wire for calorimeter | Each box contains wires, diameter meters, length mm, combustion heat value J/wire.
Platinum-copper-nickel wire with the diameter of the ignition wire or other metal wire or cotton thread with known calorific value
If cotton thread is used, it should be white cotton thread with uniform thickness and no wax coating
Each The heat released by this kind of ignition wire when igniting is as follows
Iron wire, nickel-chromium wire, copper wire and cotton wire/Hebi Tianrui Coal Laboratory Equipment Co., Ltd. consultation phone mobile phone
Ignition uses ~ power supply, which can be supplied by AC power through a transformer . A voltage-adjusting rheostat and an indicator light or ammeter to indicate the ignition status should be connected to the circuit. The ignition voltage should be determined by testing in advance. Method: Connect the ignition wire and conduct the test in the air. In the case of fuse ignition, adjust the voltage so that the ignition wire reaches bright red within ~. In the case of cotton wire ignition, adjust the voltage so that the ignition wire reaches dark red within ~. After the voltage and time are determined, the voltage, current and energization time should be accurately measured in order to calculate the heat generated by the electrical energy. If cotton thread is used to ignite, connect a section of diameter approximately between the two electrode pillars above the flame shield
Chrome wire, the middle part of the wire is pre-wound into a spiral for several turns to concentrate the heat. Then clamp one end of the cotton thread in the spiral and the other end is connected to the sample through the small hole (diameter ~) in the center of the flame shield. According to the difficulty of igniting the sample, adjust the amount of cotton thread overlap.
