摘要: 对4株中等径级华山松(Pinus armandii)树木涂敷钢结构防火涂料,在4株试验树木和1株对比树木共取得39个不同规格的试件。对试件进行不同油量情况下的直接燃烧试验,并计算韧皮部死亡率。结果表明,钢结构防火涂料对华山松树干韧皮部具有明显的保护作用。

Abstract: Fire resisting coatings for steel structures was coated on 4 bole of middling size Pinus armandii in early forest fireproof period in Kunming area in the field.39 different specification specimens were obtained from 4 test trees and 1 contrast tree.Combustion experimentations of 39 specimens were tested with different amounts of gasoline,and the mortality rate of phloem was calculated.The results showed that fire resisting coatings for steel structures had significant protective effect on phloem of Pinus armandii bole.

Key words: fire resisting coatings for steel structures, Pinus armandii, bole, protective effect
