There are a lot of fire grading standards, in general, the plastics industry in accordance with the standards of UL94, plastics flame retardant grade wool Weifang by HB, V-2, V-1 to V-0 incremental, there is a common / 8V0,1 / 16V0 retardant wool manufacturer, 1 / 32V0 (often called domestic 3.2V0,1.6V0,0.8V0), in order to increase the difficulty, according to which specific V0 rating depending on the thickness of the spline. The classification of flame retardant wool, according to different standards, different division level. Divided into standard building fire: A1, A2, B, C, D, E, F in the standard method, the partakers: M0, M1, M2, M3, M4 depends on what you are specific aspects of the fire may be . Shandong Antai New Material Technology Co., Ltd. Main retardant wool, welcome new and old customers to buy. Covering the role of fire retardant wool: combustible materials after adding flame retardant, flame retardants at high temperatures to form a glassy or stable foam cover, cut off oxygen, with insulation, oxygen, combustible gases to prevent escape outwards the role, so as to achieve the purpose of fire-retardant. Can produce crosslinked structure more stable solid matter or carbide layer such as organic phosphorus flame retardant heat. On the one hand the formation of carbonized layer can prevent further polymer pyrolysis, on the other hand can prevent the thermal decomposition of material into the interior of the combustion process involved in the gas phase. Shandong Antai New Material Technology Co., Ltd. Main retardant wool, welcome new and old customers to buy. My company provides products flame test analysis. Retardant finishing process optimization: flame retardant finishing process, take the process as follows: casual hair → dipping → dehydration → washing → dehydration → drying. In the optimization process, select the factors of pH, temperature, concentration, time of these four can significantly affect the flame retardant effect. Because flame effect can be measured by the length of the carbon fabric, limiting oxygen index values, than burning, smoldering time to represent, and the amount of adsorption of these values ??with the flame retardant fabric has a direct relationship, it can be measured by the fiber or to measure the rate of weight gain fabric flame retardant effect obtained. And this method is simple, reproducible, high accuracy, simply by weighing constant temperature can be measured. Shandong Antai New Material Technology Co., Ltd. Main retardant wool, welcome new and old customers to buy. My company provides products flame test analysis.
