White Flash Natural Temperature Meter Plastic Burn Test , 2 Mm Plastic Material Testing
Scope of application:
ZY6157 plastic combustion performance test - flash point and spontaneous combustion point tester are suitable for determining the combustion performance of materials, products or components in heat or flame under laboratory conditions. However, it cannot be used as the basis for assessing the fire risk of materials, products or combinations. The test results can be used as a factor to evaluate fire risk. The method provides for the determination of flash temperature and spontaneous combustion temperature of plastic with hot air test furnace.
Meet the standard:
GB/T4610 the determination of temperature of temperature in plastic hot air furnace. This method provides for the determination of flash temperature and spontaneous combustion temperature of plastic with hot air test furnace.
1, flash temperature: plastic material thermal decomposition released flammable gas, just can be the small flame lit, then the sample minimum initial temperature of the surrounding air, called the flash temperature of the material
2. Flash point. : spontaneous combustion temperature of the plastic material is heated after reaching a certain temperature, without external light source, explosion, flaming or by flameless combustion, the minimum initial temperature of the surrounding air sample was called the spontaneous combustion temperature of the material, referred to as "spontaneous combustion.
3, traditional self coupling transformer control method, thermal components in the thermal cycle by the current is too high, more than melting pot ideal for current requirements, the machine adopts the modern electronic design automation, using SCR technology, thus significantly prolong the life of the furnace.
4. The thermocouple in the furnace, the sample center thermocouple and the thermocouple in the sample disc are equipped with the ammeter and voltmeter to set the temperature of the heating furnace rapidly
5, test apparatus including: inside the furnace shell, furnace tube, casing, sample plate, heating cover, thermal insulation, thermocouple, air source, temperature control device, igniter, scales, timers, fume hood, using electric heating wire winding on the furnace tube, outside the bread made of refractory semicircle jacketed.
6. The insulating layer is filled with asbestos and is filled between the semicircle jacket and the furnace shell. The filling thickness is about 65mm.
7, thermocouple diameter 2 mm nickel chrome for a nickel silicon embedded thermocouple T, T, T three root, respectively located under the sample center, sample plate from the outer one omm and position such as close to the heating coil in the heating jacket, and connect with temperature recorder.
8. The air source is filtered through a copper tube to stabilize and control the circular space between the tube and the inner casing, and then enter the inner casing from the bottom. The air flow is measured by rotameter or other suitable device.
