【Scope of application】: This test furnace is developed according to the technical indicators and requirements stipulated in the national standard GB/T5464-2010, and is suitable for specifying the test method for evaluating the combustion performance of building materials under laboratory conditions. It is suitable for testing the combustion performance classification of A-class fireproof materials in the combustion performance classification of building materials GB8624 【Compliance with standards】 GB/T5464-2010 GB/T8624 ISO1182 Fire reaction test — non-flammable test of construction products [Instrument features]: 1. Dual control mode: the operation can be controlled on the touch screen, or it can be controlled on the computer, and the operation mode can be easily switched; one device can be operated by several computers at the same time, and several computers can be online at the same time, which can realize LAN sharing; (users bring their own computers and printers; the host computer software, router, network cable will be sent with the device) 2. With automatic stakeout function, the sample can be automatically put into the furnace chamber after the temperature is stable, and the specimen basket will automatically rotate 90 degrees after the furnace outlet, when changing the sample. The automatic stakeout process can be stopped at any time, and the specimen basket can be automatically returned to the initial position; 3. Microcomputer technology and triac technology are used to adjust the temperature of the furnace body through power 4. High degree of automation, the temperature in the furnace, the specimen center, and the specimen surface temperature are displayed and recorded during the test, and the operation prompt will automatically pop out for the test step 5. Historical curves can be queried to automatically judge temperature balance 6. The testing process is safe, reliable and easy to operate 7. Customized version of mold molded refractory furnace, good thermal insulation performance 8. With high-quality bar heaters, the furnace temperature can be raised to 900 °C 9. PLC+NAbview professional software displays the temperature inside the furnace, the center temperature of the specimen and the temperature curve of the specimen surface in real time, which can realize automatic control, data acquisition and processing, data storage and output of measurement results. 10. The top is equipped with an observation mirror, which is convenient for users to safely observe the combustion status of the specimen in the furnace. 【Technical Parameters】 1.
