| Popis: | The extraction and use of asbestos have been banned around the world because of its damage effects to the human health, it leads to studies of new materials in order to replace asbestos in several processes. The objective of this paper is to apply the simplex lattice planning and the mixture model in the manufacture of diaphragms. A mixture model was performed according to the simplex lattice, using four polyethylene microfibers (MF's) of different lengths, with 1st degree polynomial, adding inner and central points and a repetition, generating 18 mixtures. The results showed that microfibers of greater length have a greater influence on the diaphragms properties, presenting a more significant result on permeability. From the linear regression it was possible to estimate a mathematical model combining the three properties of the diaphragm, presenting a correlation of 92.12%. |
