Abstract
Disclosed is a material for a tempering process of glass plates utilizing a so-called contact process. It proposes a material with a base of an arrangement of thin metallic threads exhibiting a heat resistance on the order of 0.25.multidot.10.sup.-3 to 2.5.multidot.10.sup.-3 m.sup.2 .multidot.K.multidot.W.sup.-1 intended to be inserted between the cooling plates and the glass of a contact-tempering installation. The process makes it possible to temper glazings sufficiently so that they are used as automobile glazings and the durability of this thread-based material is compatible with an industrial usage.
Claims15
In an installation for contact-tempering glass plates, said glass plates having a thickness of 1 to 10 mm, said installation including cooling plates mounted so as to be movable toward one another for holding the glass plates positioned therebetween, a layer of material supported by each of the cooling plates for direct contact with the glass plates such that the glass plates are contacted only by the material when the glass plates are held by the cooling plates, each said material comprising a heat resistant material having a heat resistance of between about 0.25.multidot.10.sup.-3 and 1.multidot.10.sup.-2 m.sup.2 .multidot.K.multidot.W.sup.-1,
- wherein said material comprises threads having a diameter of less than 50 microns, at least some of said threads being metallic.
