Abstract

L'invention concerne un procédé d'évaluation de matériau peint par pulvérisation, un procédé d'estimation d'indice d'évaluation de matériau peint par pulvérisation, et un procédé de détermination d'une quantité d'utilisation d'un agent de revêtement de protection contre la lumière. Dans le procédé d'évaluation de matériau peint par pulvérisation : un dispositif de mesure de taux de lumière directe 10 est utilisé pour mesurer, dans les mêmes conditions météorologiques, un taux de lumière directe sans agent de revêtement lorsqu'aucun agent de revêtement de protection contre la lumière n'est appliqué, et un taux de lumière directe avec agent de revêtement lorsqu'un agent de revêtement de protection contre la lumière est appliqué ; un gradient est défini comme un indice direct, le gradient étant obtenu lorsque le taux de lumière directe avec agent de revêtement mesuré est exprimé sous la forme d'une équation de régression d'une fonction linéaire par rapport au taux de lumière directe sans agent de revêtement ; et l'indice direct est utilisé en tant qu'indice d'évaluation d'un matériau peint par pulvérisation revêtu d'un agent de revêtement de protection contre la lumière, pour estimer l'indice direct d'un matériau peint par pulvérisation qui est évalué, et pour déterminer une quantité de revêtement par unité de surface et une quantité d'utilisation de l'agent de revêtement de protection contre la lumière. Ceci permet d'effectuer une évaluation comparative du taux de lumière directe et d'un taux de lumière diffusée entre différents matériaux peints par pulvérisation. Le procédé d'estimation d'indice d'évaluation de matériau peint par pulvérisation permet d'estimer le taux de lumière directe et l'indice de lumière diffusée à partir de la quantité de revêtement par unité de surface pour le matériau peint par pulvérisation qui est évalué. Le procédé de détermination d'une quantité d'utilisation d'un agent de revêtement de protection contre la lumière permet de déterminer la quantité d'utilisation de l'agent de revêtement de protection contre la lumière à partir de la quantité de revêtement par unité de surface et de la zone qui doit être peinte par pulvérisation.
