1. The effect of flame test sample into the sample holder, the use of lower face, covered forehead, closed the door pour retardant fabric manufacturers, 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 complete, open the ventilation equipment to clear the chamber of smoke, gas and debris, and then measure the next sample. The flame spread rate calculations. Shandong Antai New Material Technology Co., Ltd. Main fabric flame retardant fabric, welcome new and old customers to buy. Combustion and flame are very complex process and involves many factors influence the mechanism of a flame retardant system is strictly divided into a certain kind of hard, in fact, a lot of flame retardant system simultaneously in several the mechanism works. Retardant finishing processes polyester fabric modification method is simple, low cost Shandong retardant fabric, from the flow of the diversity and extent of the requirements for flame versatility of view, favorable than the original wire modification methods. However, if the amount is more flame retardants, the feel and color of the fabric greater impact. Shandong Antai New Material Technology Co., Ltd.
