    System Architecture & Testing Workflow of Fire Retardant Coating Test Furnace<\/h3>\n

    Standardized Testing Workflow:<\/strong><\/p>\n

      \n
    1. Apply the steel structure fire-retardant coating to the 500mm \u00d7 500mm \u00d7 6mm standard steel plate specimen and allow it to cure per standard instructions.<\/li>\n
    2. Mount the specimen onto the test furnace opening, attaching K-type thermocouples to the unexposed face to measure heat conduction.<\/li>\n
    3. Select the target fire-resistance duration (e.g., 180 or 360 minutes) on the touch screen or wireless PC interface.<\/li>\n
    4. Trigger the automatic spray burner; the system heats up following the GB 14907 \/ ISO 834 curve while continuously recording furnace pressure and unexposed surface temperature.<\/li>\n
    5. Upon test completion, the furnace automatically terminates heating, saves test records, and initiates forced exhaust cooling.<\/li>\n<\/ol>\n

        Steel Structure Fire Retardant Coating Sample Test Furnace FAQ<\/h3>\n

        Q1: What is the main evaluation metric for GB 14907 steel structure coating tests?<\/h4>\n

        A:<\/strong> The primary metric is the Thermal Insulation Efficiency \/ Fire Resistance Limit<\/strong>, defined as the time required for the average temperature of the unexposed steel plate to reach a critical limit (typically 500\u00b0C or specified temperature rise) under the standard fire time-temperature curve.<\/p>\n

        Q2: How does the wireless PC control benefit multi-furnace laboratory operations?<\/h4>\n

        A:<\/strong> Wireless linkage enables a single central computer terminal to wirelessly connect to and synchronously control multiple GTL-50 test furnaces. Laboratories can execute simultaneous batch tests, collect live data, and archive reports without extensive cabling.<\/p>\n

        Q3: What safety mechanisms are built into the diesel combustion system?<\/h4>\n

        A:<\/strong> The GTL-50 includes automatic flameout detection with auto re-ignition capabilities, power-off memory protection, and over-temperature safety cut-offs to guarantee safe, unattended laboratory testing.<\/p>","protected":false},"excerpt":{"rendered":"
