ОЦЕНКА ВЛИЯНИЯ ПОРОДЫ ДРЕВЕСИНЫ НА ЭФФЕКТИВНОСТЬ ОГНЕЗАЩИТНОЙ ОБРАБОТКИ ПРОМЫШЛЕННЫМИ АНТИПИРЕНАМИ
Аннотация
Данная статья посвящена экспериментальной оценке эффективности двух промышленных огнезащитных составов (RAUM-PROFIE и СЕНЕЖ). Исследование проводилось на древесине восьми пород: сосна, ель, лиственница, пихта, дуб, бук, берёза, осина. Оценка результатов показала, что привес образцов после пропитки и изменение кислородного индекса существенно зависят от плотности и содержания экстрактивных веществ в древесине. Наибольший прирост кислородного индекса зафиксирован для пихты и осины, наименьший – для лиственницы и дуба. Установлено, что эффективность огнезащитной обработки не является универсальной и должна учитывать особенности структуры строения древесины, химические и физико-химические особенности породы.
