Die kwaliteit van die geweefde sak is onlosmaaklik van die gewig van die gram. Oor die algemeen, hoe hoër die gewig, hoe dikker die sak, hoe beter die kwaliteit. Die maat is in gewig. The base bag of the grootmaat sakke is calculated by the square meter, wat oor die algemeen is 160 gram per vierkante, 180 gram, 190 gram, 200 gram per vierkante. If you cut the piece down, measure the size, and then weigh the weight, you can calculate the square of the square of the square. The weight of the woven bag directly determines the thickness of the woven bag. The calculation formula is as follows: single bag weight = length * breedte * 2 * square gram weight.
Byvoorbeeld, thickness 60 microns, grootte 180 * 270cm
weight is volume * density, volume 0.006 * 180 * 2 * 270 = 583.2 density
PE is 0.917
583.2 * 0.917 = 531.2952 gram
There are relatively cumbersome calculation method: (number of latitudes) /2000.911=square gram weight
The above is the calculation method of the gram weight of the base fabric.
There is no certain calculation method for the grootmaat sakke, because the bulk bags has more accessories, it has to be decomposed one by one. , one by one, and finally added together. (Oor die algemeen, the composition of the grootmaat sakke; the main body, the sling, the upper cover, the bottom, the upper and lower feeding ports, the ties, the closing rope, the file bag, the label, the reinforced cloth, ens.) and the base cloth to be determined by the different quality to be loaded The weight of the sling is not the same.
