Abstract

Formaldehyde was found to off-gas from flint sandpaper that contained an urea-formaldehyde resin as the minor component in a double glue system. Approximately 2000 sheets of sandpaper in a 115 m3 (4050 ft3) ship's storeroom with no mechanical ventilation produced a formaldehyde concentration of at least 4.5 ppm that was uniform throughout the compartment. A contributing factor was elevated compartment temperature due to high ambient temperature and the heating of the ship's steel hull by direct exposure to the sun.

摘要

人们发现，含有脲醛树脂作为双胶系统次要成分的燧石砂纸会释放甲醛。在一个115立方米（4050立方英尺）且无机械通风的船舶储藏室中，约2000张砂纸产生的甲醛浓度至少为4.5 ppm，且在整个舱室内浓度均匀。一个促成因素是，由于环境温度高以及船舶钢 hull直接暴露在阳光下受热，舱室温度升高。
