摘要:
The invention concerns transparent fire break glass panels. The inventive glazing comprises at least two glass sheets and an intumescent phosphate-based material layer, layer which is located between said two glass sheets. The intumescent material comprises pyrogenous silica or a mixture of pyrogenous silica and alumina which enables said material to be exempt from creep deformation at temperatures preceding the expansion of the intumescent material in fire resistance tests. The inventive glass panels have improved heat resistance, and are more easily manufactured than similar glass panels in prior art.

The method comprises the steps of applying a masking agent at part of a surface of the substrate, depositing the coating film over at least part of the surface of the substrate which is covered by the masking agent and over at least part of the surface of the substrate which is free of the masking agent and removing the masking agent from the substrate. The masking agent is preferably removed by the application of water.

A glazing panel carrying a coating stack comprises in sequence at least: a glass substrate, a base antireflective layer, an infra-red reflecting layer, and a top antireflective layer in which at least one of the antireflective layers comprises at least a) a mixed oxide layer which comprises an oxide which is a mixture of Zn and at least one additional material X, in which the atomic ratio X/Zn is greater than or equal to 0.03 and in which X is one or more of the materials selected from the group comprising the elements of groups 2a, 3a, 5a, 4b, 5b, 6b of the periodic table, and b) a layer which comprises a nitride comprising at least one of the materials Al, Si and Zr. The glazing panel is particularly suitable for heat treatment and incorporation in vehicle windscreens.

Before heat treatment of a glass sheet, a layer of enamel paint is printed on at least one portion of the glass sheet (5), either by screen-printing or tampon-printing, in the form of at least one block (4), on which at least one laser beam is directed in such a way that it removes a layer of enamel paint at desired positions (7), thereby providing the glass sheet with specific immediate information and identification data relative to date, time and/or process equipment which are stocked in a computer database for at least three years.

A laminated glazing panel (10) is assembled in a frame (15) by a fixing member (21) secured to a surface of one of the sheets of glass at an attachment portion of the glazing panel. The attachment portion of the glazing panel comprises a weakness zone (23), for example a zone of non-adherence, positioned between the two sheets (11, 12) of glass adapted to facilitate separation of at least a portion of the glazing from its fixing member. The glazing panel (10) may be easily removed from its frame (15) at the end of its life.

A glazing panel (10) is assembled in a frame (15) by a fixing member (21) secured to a surface of one of the sheets of glass at an attachment portion of the glazing panel. The attachment portion of the glazing panel comprises a heatable fracturing element (23, 24) adapted to fracture at least a portion of the glazing panel to facilitate separation of at least a portion of the glazing from its fixing member (21). The glazing panel may be easily removed from its frame (15) at the end of its life.
摘要:
The present invention relates to a coloured soda-lime glass of high light transmission. It comprises less than 0.4% by weight of total amount of iron, expressed in the form of Fe2O3, has a redox ratio of at least 30% with an FeO content of at least 0.08% by weight and comprises in total at least 5 ppm and at most 1500 ppm by weight with respect to the total weight of glass of at least one of the following colouring agents in the respective amounts indicated: Cr2O3 from 0 to 500 ppm, V2O5 from 0 to 1000 ppm, Co from 0 to 100 ppm and Se from 0 to 10 ppm. This glass is suitable as glazing for motor vehicles and as glazing intended for buildings.
摘要:
A method of producing a copper-based mirror for use in furnishings and decoration comprises a transparent vitreous substrate and a reflective copper layer, characterised in that the substrate is treated with an aqueous solution of stannous chloride prior to the so-treated substrate being covered by a reflective copper layer, and the reflective copper layer is applied by a vacuum deposition to a thickness of at least 40 nm.
