The efficiency in handmade placement was conditioned by the initial cellulose / water mixture (38.4 gr Cell/100gr water) and by the porosity of the material since, in the case of the less porous samples, a superficial runoff / loss of water that had not been absorbed occurred, even though this factor had a human component according to the handling style and the pressure applied. In any case, handmade poultices were a third denser in comparative terms (they are 1/3 heavier in terms of cellulose per cm 2 ). The process of placing “handmade” poultices was much slower than the “GPM” version, and the adhesion of the poultice was much lower, being difficult to place them on inclined surfaces and impossible in an inverted position (upside down). [15] (Lubelli et al 2010) determined an average pore size of 15 microns for BW40 Arbocel® compresses; from the SEM images (fig 3) it could be deduced that the “GPM” poultice had a slightly superior pore size but with an homogeneous distribution, whereas the “handmade ” poultice would have a slightly lower pore size (the fiber is more packed and the bulk density is somewhat higher) but with a more irregular distribution and with the presence of macropores thatdid not exist in “GPM” poultices.

The petrophysical values have been calculated on theaverage volume of the dry papettaand with the density value of the cellulose of 1.44 . d) Water absorption: Evaluation with the infiltrometer The infiltrometer is a device that is used to know the infiltration capacity and water parameters in soils [16] and is very suitable in poultices for two reasons: 1) It allows to measure the infiltration when placed on the substrate that wants to be studied. 2) Poultices are similar to soils both in its physical characteristics and in the fact that they have tobe studied using a method that does not modify its original texture. The infiltrometer allows to experimentally measure the suction coefficient of the poultice in a quick and easy way. This data is very hard to calculate by other means. The device was placed on the poultice with a water height pressure of 2 mm. With this pressure (which can be considered equal to atmospheric © 2023 Global Journals Volume XXIII Issue II Version I 8 ( ) Global Journal of Human Social Science - Year 2023 C Poultices Generated Mechanically with Compressed Air: “Gunpoint Mix System” Characterization and Properties.
