夹层安全玻璃是化学家ÉdouardBénédictus在1903年的一次实验室事故后发明的。一个装有塑料硝酸纤维素的玻璃烧瓶掉了下来,粉碎了但没有破碎。 在听到车祸导致玻璃碎片受伤后,他于1909年申请了专利。

带有夹层安全玻璃的典型“蜘蛛网”裂纹的汽车挡风玻璃。

夹层玻璃是一种安全玻璃,当破碎时会保持在一起。 万一发生破裂,它会在其两层或更多层玻璃之间通过一个通常为聚乙烯醇缩丁醛(PVB),乙烯-醋酸乙烯酯(EVA)或热塑性聚氨酯(TPU)的中间层固定在适当的位置。 中间层即使破裂也能保持玻璃层的粘结,其高强度可防止玻璃破裂成大块的锐利碎片。 当冲击力不足以完全刺穿玻璃时,会产生特征性的“蜘蛛网”开裂图案。 在这种情况下 … 继续阅读(7分钟阅读)

A glass flask coated with the plastic cellulose nitrate was dropped, shattering but not breaking into pieces. In 1909 he filed a patent, after hearing of a car accident causing injury by glass debris.”

    And the salesman said “hit it with a hammer to see if I’m lying”

    I work in the glazing & locks industry & I didn’t know that. Everyday is a school day

    I was told the glass jars of acid were laminated when I worked in a lab. I didn’t pay any attention. Then a lab worker really wanted to show me. A week or so later we finished off a bottle of acid and he made this big production of showing everyone. And he dropped the bottle into a large carboard box. It did what it was supposed to do and shattered inside its own laminated coating. Not as impressive as he made it out. But nice to see that they’re thinking of me.

    At least half of all inventions seem to be discovered by pure chance when messing up your actual experiment.

    I’m an engineer that works with laminated glass. This story is part of a lot of presentations I give to customers explaining the history of the product. Surprised to see it today on my front page!

    Any glass questions… AMA!

    I love the number of scientific breakthroughs come from accidents. There are no mistakes only happy accidents.

    Well I thankful to him …for my impact windows so much better than hurricane shutters.

    It seems chemistry is based on accidents.
