Establishing patterns of mass transfer under the action of water on the hydrophobic coating of the fire-retardant element of a tent

This paper reports an analysis of the flame retardants for fabrics that has revealed fact meagerness data to explain and describe process fire protection, specifically neglect elastic coatings, leads structures made from are ignited under influence a flame. Devising reliable methods study protection conditions results in design new types fireproof materials. Therefore, there is need determine formation barrier water mass transport establish mechanism slowing down penetration through material. In this regard, estimation-experimental method been constructed determining transfer action when using hydrophobic coating, which makes it possible assess penetration. Based on experimental theoretical dependences, intensity flow determined, 0.000177 kg/m2, ensures fabric resistance. The have proven waterproofing involves inhibition by insulating surface with coating. It should be noted presence coating blocking moisture Such behind effect likely factor adjusting integrity object preserved. Thus, sample coated repellent demonstrated, after exposure water, amount absorbed did not exceed 0.00012 kg, and, without repellent, was 0.01 kg. reason assert possibility targeted adjustment processes related coatings could form protective layer material, inhibits rate
