1. The effect of flame test sample into the sample holder, the use of fire retardant fabric manufacturers face down, covered with top door, shut the door on dumping, set to open on the automatic key. Press the ignition key and the timing of key buttons, lit a Bunsen burner flame for 15 seconds sample is applied. 2. Measure the distance of flame spread and time, recording time to 0.1 seconds, the distance to the nearest mm, the flame spread to the first line at the beginning of the timing mark and measure distances. 3. The test is completed, open flame retardant fabric ventilation equipment to clear the chamber of smoke, gas and debris Weifang retardant fabric, and then measure the next sample. The flame spread rate calculations. Shandong Antai New Material Technology Co., Ltd. Main fabric flame retardant, welcome new and old customers to buy. My company provides products flame test analysis. Polyester fiber is one of the widely application of synthetic fiber, it's burning like other synthetic polymer materials, and high-temperature heat source contact, thermal cracking reaction occurred after heat absorption, thermal cracking reaction of flammable gas Shandong fabric flame retardant, easy combustible gas under the conditions of air (oxygen) exists, combustion takes place, after the heat of combustion is absorbed by the fibers, and the fibers continue to promote further combustion and pyrolysis to form a loop.
