过去,有些仓库和商店因对赛璐珞制品的性质不够了解,缺乏严格管理和妥善保管,曾发生过一些较大的火灾事故,给国家财产造成了不应有的损失。这个教训是深刻的,我们应该认真汲取。赛璐珞属于热塑性塑料,也称硝酸纤维素塑料。它具有弹性大、机械强度好、透明度高、易于加工成型、着色鲜艳、容易燃烧等特点。它的主要成分有70～75％的硝化棉、25％左右的樟脑和少量颜料、染料等。赛璐珞35℃以上缓慢分解,80℃开始软
In the past, some warehouses and shops, which did not know enough about the nature of celluloid products, lacked strict management and safe custody. Some large fire accidents had occurred and caused undue losses to state property. This lesson is profound. We should learn it carefully. Celluloid is a thermoplastic, also known as nitrocellulose plastic. It has a large elasticity, good mechanical strength, high transparency, easy molding, brightly colored, easy to burn and so on. Its main components are 70 to 75% of nitrocellulose, about 25% of camphor and a small amount of pigments, dyes and so on. Celluloid slow decomposition above 35 ℃, 80 ℃ began to soft
