网格布的克数与目数换算方法
网格布克数是指单位面积的质量，通常以克/平方米表示。需要注意的是，这个质量通常指涂覆后的成品质量。
根据JG 149-2003标准规定，单位面积质量应≥130克。在保温砂浆施工中通常遵循此标准，外墙施工同样适用该规范。
网格布目数的计算方法较为特殊：
- 并非简单地依据孔径计算
- 按照纺织工艺中的经纬线数量计算
- 以此方法计算出的孔径会略大于实际方形孔径
Practical Conversion Method:
The grammage of mesh cloth refers to the mass per unit area, generally expressed in grams per square meter (g/m²). It's important to note that this mass usually refers to the finished product after coating.
According to JG 149-2003 standard, the unit area mass should be ≥130 grams. This standard is commonly followed in thermal insulation mortar construction and is also applicable for exterior wall construction.
Regarding mesh count calculation:
- Not simply based on aperture size
- Calculated according to the number of warp and weft threads in textile process
- The calculated aperture will be slightly larger than the actual square aperture
实际应用技巧：
在实际应用中，可以简单地使用方形孔径的边长作为目数。例如，标准网格布的孔径为5mm时，可表示为5×5目。
Practical Tip: In practical applications, the side length of the square aperture can be simply used as the mesh count. For example, when the aperture of standard mesh cloth is 5mm, it can be expressed as 5×5 mesh.
