Experimental and Statistical Study of the Optimization of Fire retardants in a Formulations of Waterborne Intumescent Fire-resistant Coatings for Steel Structure Using Uniform Experimental Design

摘要

This paper presents a uniform design methodology for computer aided experimental design for intumescent fire-resistant coating (IFRC) formulations, exemplifies the benefits of using experimental design together with statistical software to facilitate the optimization of fire retardants in a formulation of an IFRC for structural steelworks. By applying a statistical multivariate design for the screening experiments, many intumescent fire retardants were evaluated in comparatively few experiments. In this work, prior information has been used in the form of a model, based on historical experiments. A uniform design criterion is used to design a few additional experiments so that the resulting model can have an acceptable prediction power. A confirmatory experiment step is shown that a design which uses the uniform design methodology taking advantage of the experimental data collected from the design of experiments that using fewer trials gives a model with equivalent prediction capability. This can be critical where the practical approach which often requires a considerable amount of experimental work and may be costly and time consuming to perform.
