Retardant foam coating knife coating method of the present embodiment blade coating process using conventional methods, to select a suitable tool from the fabric according to the vehicle speed, temperature. In order to make the plastic coating after extrusion scraping penetrate into the fabric, the coating was pressed to the sword suitable distance (the distance l ~ l5mm downwardly within selection, coating knife coating platform from the front and rear distance 1 ~ 20m selection) Weifang fabric flame retardants, temperature control in 140-l60 ℃, the speed according to the amount of glue, drying conditions regulating the general control 10-35m / min. Shandong Antai New Material Technology Co., Ltd. Main fabric flame retardant, welcome new and old customers to buy. Retardant effect of the test sample into the sample holder 1. Place the fabric flame retardant manufacturers, use face down, covered with fire retardant fabric manufacturers Weifang forehead, close the dump door, 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.
