那你应该查查发生什么反应，产生的是什么所气体

高折树脂片加工过程中会产生大量热和有害气体. 有少量的硫,硝酸钾.大量的甲醛和苯,挥发时候会产生毒气. 在加工过程中,建议您使用防毒面罩,以防有害气体. 如果你是使用眼睛者,建议您使用法国"依视路"苊就用这.

高折树脂片加工过程中是有毒的啊。我从事过树脂生产只有几少数的树脂没有毒。

谢谢回答！！！

在作业中高折树脂片加工过程中散发的气味是有毒的。因为里面添加了甲醛和苯，挥发的时候，是有毒的，所以在作业中，应该做好相应的保护措施，吸入过多是有害的

高折镜片中添加了硫所以臭 量少，不会有什么问题 但是粉尘要注意点 一定要保证温湿度，，通风设施一定要好。。。。
