在砂布生产的工艺过程中有下列工序:上面浆→上胶→上砂→上复胶→上甲醛,然后再进行烘干、切断,上甲醛这道工序到底起到些什么作用呢? 经过长期的生产实践,针对我厂砂布脱砂率高,磨削性能不稳定等情况,我们对整个生产工艺过程进行了分析,发现上甲醛工序,甲醛用量对砂布质量有一定影响。我厂砂布生产 In the process of emery cloth production, there are the following processes: top-slurry → sizing → sand-up → top-slurry → top-formaldehyde, and then drying and cutting. What does this process of formaldehyde play in the end? The production practice, in view of the high sand removal rate of abrasive cloth and unstable grinding performance of our factory, we analyzed the entire production process and found that the formaldehyde process has certain effect on the quality of the sand cloth. Our factory abrasive cloth production
