摘要:
The invention relates to a process for manufacturing a printed laminated glazing unit composed of two glass sheets separated by an interlayer adhesive sheet, comprising the steps consisting in screen printing, with a printing composition, at least one face of one of the sheets making up the glazing unit using a screen printing screen; and in assembling the various sheets making up the glazing unit, at least one of which has been screen printed. In this process a screen printing screen is used that comprises two superimposed fabrics, the fabric (I) intended to be placed opposite the face to be screen printed having a smaller mesh opening than the other fabric (S), the difference in mesh opening between the two fabrics lying in the range from 22 to 65 μm.
摘要:
A grinding wheel is suited for shaping glass, notably glass that is less than or equal to 4 mm thick. This grinding wheel has at least one abrasive portion formed of at least one metal binder and of diamonds distributed in the binder. The binder has a Rockwell B hardness of between 95 and 105 and is tungsten-based. The diamonds have a size of between 75 and 95 μm and a concentration of between 2.2 ct/cm3 and 2.64 ct/cm3. Glass, in particular for shaping motor-vehicle glazing units, can be shaped with this grinding wheel, making it possible to achieve travel speeds greater than or equal to 30 m/min.
