Measuring Tool Kit for Express Analysis of Intumescent Fire Protection at a Construction Facility

Abstract

Purpose. Existing methods for checking the quality of intumescent coatings do not allow determining the implicit properties of these coatings, for example, the properties of foamed coke (FC), which is formed from a layer of intumescent paint during a fire. The authors analyze the issues of developing a measuring tool kit to evaluate intumescent coatings outside the laboratory, thus minimizing the possibility of using inappropriate quality paints and excluding violations of the work technology. Methods. The work uses theoretical research and experimental methods for measuring physical and mechanical parameters. Findings. The results of studies of the FC structural and mechanical properties obtained from the most popular intumescent paints Defender M Solvent are given. A scheme for a comprehensive assessment of intumescent coating properties is developed. To assess the FC quality a set of measuring tools is proposed, including equipment of our own design. Research application field. The results obtained are the basis for the development of an express analysis methodology for intumescent coatings quality directly at the construction site to ensure fire safety of these facilities. Conclusions. The proposed measuring tool kit makes it possible to assess the quality of the foamed coke by the following parameters: layer thickness, intumescent coefficient, compressive strength, shear-detachment strength. This set of parameters is sufficient for assessing the working properties of a fire proof coating and allows revealing hidden defects of the intumescent paint directly at the place of its application.
