A contribution to the resistance of combined plywood materials to abrasion
The aim of the paper was to propose the methodology of testing the abrasion resistance of combined water-proof plywood materials with the phenol-formaldehyde foil surface finish and to assess the surface resistance of a new combined plywood material of a given construction to abrasion. For sheathing...

| description | The aim of the paper was to propose the methodology of testing the abrasion resistance of combined water-proof plywood materials with the phenol-formaldehyde foil surface finish and to assess the surface resistance of a new combined plywood material of a given construction to abrasion. For sheathing, phenol-formaldehyde foils with the low content of resins were used, which are combined with unwoven and woven glass fibres highly resistant to mechanical wear. The paper for phenol-formaldehyde foils manufactured of sulphate pulp (basis weight 60 g/m2) was impregnated by a low-molecular resin with the resin deposit 150% DM (dry matter) per paper DM. To evaluate the newly designed material our testing methodology was prepared in such a way that it will conform to related European standards. It is completed by the method of sampling and preparation of samples for tests including their acclimation. According to our proposal, measurements were carried out of selected constructions of water-resistant plied veneer materials with jackets of various basis weight combined with glass fibres. Data on the abrasion resistance were acquired which can be considered to be reliable. The values of abrasion resistance were assessed with respect to standards valid in the EU which determine fields of their use. |
