密度板表面产生砂痕的原因揭秘

来源:admin发布时间:2019-03-02 14:48:07

砂光密度板是咱们常说的砂光板,是使用砂光机精加工,进步加工件的尺寸精度、外表平直度和光洁度。经过砂光工艺后,有时咱们会看到密度板外表有凸凹痕。
Sanding density board is what we often call sanding board. It uses sanding machine to finish and improve the dimensional accuracy, surface flatness and finish of the parts. After sanding process, sometimes we can see the surface of the density plate has bumps and dents.
那么形成密度板外表砂痕缺陷的原因是什么呢?济南密度板公司为我们回答。
So what is the reason for the formation of sand mark defect on the surface of density plate? Jinan Density Plate Company answers for us.
因为密度板里有硬物形成砂带脱砂粒而发生的线条凸起砂痕,密度板内有异物,异物又分偶然性异物,如设备掉螺丝钉之类的,随机发生的异物;也有的是木材质料里夹杂的异物,如采伐木材质料时在运输过程中夹藏的沙石或许收购的木片中夹藏有的沙石;以上两种情况使砂带碰到这些硬东西后就简单出现掉砂情况,这样就形成密度板面有线条状凸起砂痕。
Because there are hard objects in the density board to form sand marks caused by sand strip debris, there are foreign bodies in the density board, foreign bodies can be divided into random foreign bodies, such as equipment screw dropping, and so on. There are also foreign bodies in the wood material, such as sandstones hidden in the transport process of cutting wood material or sandstones hidden in the purchase of wood chips. All kinds of conditions make the sand belt drop easily when it meets these hard objects, thus forming a linear and convex sand mark on the density plate surface.

密度板放置冷却时刻不够就进行砂光也会发生线条状凸起砂痕缺陷,因为密度板的胶黏剂没有彻底固化,简单粘到砂带的部分使砂带面部分受到阻塞后散热不良,使砂带失效形成密度板板面发生线条状凸起砂痕。
When the cooling time of the density plate is not enough, sanding will also lead to line-like protruding sand marks, because the adhesives of the density plate are not completely solidified, and the parts simply bonded to the belt will cause bad heat dissipation after blocking the belt face, resulting in the failure of the belt to form line-like protruding sand marks on the surface of the density plate.
