the united nations development programme undertook pilot projects on the use of methyl formate and methylal for polyurethane foam production in brazil in 2009 and 2010, respectively.
联合国开发计划署分别于2009年和2010年在巴西开展了关于使用甲酸甲酯和甲缩醛生产聚氨酯泡沫的试点项目。
a recent workshop had confirmed the use of methyl formate in australia, brazil and the united states of america in integral skin foam, specialty flexible foam and most rigid foam applications.
他汇报说,近期的一次研讨会确认,澳大利亚、巴西、美利坚合众国在自结皮、专业软泡沫和硬质泡沫应用中使用甲基溴。
he noted that there were other alternatives, such as oxygenated hydrocarbons (methyl formate, methylal) and improved co2 (water) based formulations that provided acceptable foam properties in integral skin foam and in rigid foam when a high thermal performance was not required.
他指出还有其他替代品,如含氧烃(甲酸甲酯、甲缩醛)和改良的二氧化碳(水)基配方,后者在不需要较高热性能的情况下,能在自结皮泡沫和硬质泡沫中提供可接受的泡沫性能。
