18微米对应多多少目砂纸

计量单位目有粒径有多小，如何与毫米、微米换算？ 知乎,Web虽然有多种标准，但结果都大差不差，一般来说目数×孔径（微米数）=15000，所以这也是它的换算公式，但我们也不必要进行换算，我们使用尺寸对照表就可以了，我国使用的是 Web29 rows  Jun 10, 2019  目数，就是孔数，就是每平方英寸上的孔数目。 目数越大，孔径 目数,目,毫米mm,微米μm转换关系对照表Web下面是砂纸目数和表面粗糙度的对照表。 一、砂纸目数 1 #16目：用于去除粗糙表面，特别适用于去除旧漆和腐朽的木材表面。 2 #24目：用于较为粗糙的木材表面的磨削和去除 砂纸目数和表面粗糙度对照表 百度文库
