我厂生产的硬质纤维板原来用两台1.1千瓦圆锯机来锯切裁边,噪声高达97分贝(A),纤维尘屑到处飞扬,空气中灰尘浓度超过国家规定标准9.17倍,严重影响工人身体健康。为了解决上述问题,我们对原设备进行了改造,将锯切工艺,改为无动力划切工艺,既保持了原设备的技术性能,又克服了弊病 I plant the original production of hard fiberboard with two 1.1 kW circular sawing machine to cut the edge, the noise up to 97 decibels (A), fiber dust flying everywhere, the dust concentration in the air 9.17 times the national standard, seriously affecting the workers Healthy body. In order to solve the above problems, we have rebuilt the original equipment and changed the sawing process to a non-power cutting process, which not only maintains the technical performance of the original equipment but also overcomes the disadvantages
