μm1、长度单位微米是长度单位，符号 [micron]。
1微米相当于1米的一百万分之一（此即为「微」的字义）。

网目是表示标准筛的筛孔尺寸的大小。
在泰勒标准筛中,所谓网目就是2.54厘米(1英寸)长度中的筛孔数目,并简称为目。
泰勒标准筛制：泰勒筛制的分度是以200目筛孔尺寸0.074mm为基准，乘或除以主模数方根（1.141）的n次方（n＝1，2，3……），就得到较200粗或细的筛孔尺寸，如果数2的四次方根（1.1892）的n次方去乘或除0.074mm，就可以得到分度更细的一系列的筛孔尺寸.目数越大，表示颗粒越细。
类似于金相组织的放大倍数。
目数前加正负号则表示能否漏过该目数的网孔。
负数表示能漏过该目数的网孔，即颗粒尺寸小于网孔尺寸；而正数表示不能漏过该目数的网孔，即颗粒尺寸大于网孔尺寸。

精度换算表
精度换算表■过滤袋微米级别、空气过滤效率对照表化学纤维性能表五、滤料的各种化学处理1、烧毛及压光处理尘粒具有附着在其他尘粒或与其他物体表面相互接触的特性。
当悬浮尘粒彼此接触时，就相互吸附而凝聚在一起。
粉尘的凝聚力与尘粒的种类、形状、粒径分布、含湿量表面特征等多种因素有关，可用安息角表征，一般为30°-45°。
安息角小于30°称为低附着力，流动性好，对于此类粉尘必须使用表面经烧毛处理的滤料，以提高滤料的表面积，增加滤料对粉尘的捕集率，同时也有利于清灰时将此类粉尘从滤料深部吹出；安息角大于45°称为高附着力，流动性差，对于此类粉尘必须使用表面经压光处理的滤料，以提高滤料的表面光滑度，增加滤料表面对粉尘的捕集率，防止此类粉尘钻入滤料深部后清灰困难。
2、抗静电处理分散在空气（或可燃气）中的某些粉尘在特定的浓度状态下，遇火花会发生燃烧。
所以对于易燃易爆粉尘宜选用经抗静电处理的滤布。
抗静电滤布是指在滤布纤维中混入导电纤维，使其在三维都具有导电性能（体电阻小于107Ω）。
常用的导电纤维有不锈钢纤维和改性（渗炭）化学纤维。
不锈钢纤维导电性能稳定可靠，改性化纤在经过一定时间后导电性能容易衰退。
3、防水防油处理湿含尘气体(尤其对吸水性、潮解性粉尘)会使滤袋表面捕集的粉尘润湿粘结，甚至引起糊袋。
这是袋式除尘器最忌讳的。
为此应对滤布进行防水防油处理，使其每根单纤维都具有憎水憎油性，增大滤料的表面张力，可有效地使结露的水珠与灰结合成珠状，不会渗透至滤料内部，堵塞过滤毛细通道，从而避免因结露而产生的糊袋现象。
4、易清灰处理粉尘的磨啄性与尘粒的性质、形态以及携带尘粒的气流速度、粉尘浓度等因素有关。
表面粗糙尖棱形不规则的粒子比表面光滑形粒子的磨啄性大10倍。
粒径为90微米左右的尘粒的磨损性最大，而当粒径减小到5-10微米时磨损性十分微弱。
铝粉、硅粉、碳粉、烧结矿粉等属于高磨损性粉尘。
对于磨啄性粉尘必须选用耐磨性好的经易灰处理的滤布。

不锈钢过滤网的目数与过滤精度换算表
不锈钢过淲网是做过滤网片产品最主要的原料产品，其过滤精度是一个复杂的问题，一般要依据介质本身或者设备、仪表的要求而定。通常情况下，过滤精度25微米的不锈钢过滤网可以去除肉眼可见的颗粒；过滤精度为1或者5微米的过滤网，可以去除液体中的云状悬浮物；过滤精度为0.2微米的不锈钢网，则可以去除细菌。
