摘要:
A fire-resistant glazing assembly has at least two laminated panes between which a transparent layer made of a hydrated alkali polysilicate is placed. The hydrated alkali polysilicate contains no organic antifreeze agent. Thus, on the one hand, better resistance of the interlayer to clouding due to UV radiation and, on the other hand, greater rigidity of the interlayer compound as well as good adhesion of the panes to the interlayer in a fire are obtained.
摘要:
A glazing made of at least one glass layer and at least one transparent layer of ionomer resin, wherein at least a portion of one face of the at least one transparent layer of ionomer resin is adhered to at least a portion of one face of another layer of the glazing using at least one metal chelate, preferably a metal chelate based primer composition, and the primer composition for use in such a glazing are described, to provide laminated glazings which have improved chock resistance, good optical properties, improved resistance to lamination even during cutting operations, and is economical to produce.
摘要:
A fire-resistant glazing assembly comprises two glass sheets (1, 2) connected together along their edges by a spacer (3) and a water-containing interlayer (4) between the two panes (1, 2). The spacer (3) is made of silicone rubber. A bead (6) of a heat-activated foaming material is advantageously placed between the spacer (3) and the adhesive sealing material (7) serving to provide the peripheral seal.
摘要:
An anti-fire glazing composed of two sheets of glass maintained separated by a sealed intermediate peripheral frame, between which an aqueous solution containing a dissolved salt and a gelling agent has been placed. After filling, the solution is transformed into an aqueous gel, the aqueous phase of which contains the salt in solution, and the solid phase of which is a polymer. The gelling polymer is a cross-linked polyvinyl alcohol. A dialdehyde is used as the cross-linking agent.
摘要:
A transparent cover layer of a soft elastic polyurethane for windshields or other transparent glass or plastic substrates. In order to give the cover layer an anti-fogging effect, the polyol component of the reaction mixture for the manufacture of the cover layer contains a difunctional sulfonated polyether polyol or a difunctional polyether polyol containing sulfonate groups having 0.5 to 13.2 percent by weight of OH groups and an average molecular weight of about 250 to 6500 g/mol, a trifunctional polyol having 5.1 to 12.8 percent by weight of OH groups and an average molecular weight of from 400 to about 1000 g/mol, as well as a non-ionic polyetherpolysiloxane having an average molecular weight of from 500 to 2000 g/mol.
摘要:
The removal of partial areas of a coating (11, 12) on at least one surface (37, 38) of a glass pane (2) takes place by means of a plasma jet (14, 15) which emerges from a plasma nozzle (5, 6). The plasma nozzle (5, 6) is part of a plasma unit and two such plasma units are provided. Both of the plasma nozzles (5, 6) are oriented towards each other and form a pair of nozzles. A glass pane (2) is machined between both of the nozzles (5, 6). A distance sensor (23, 24) is arranged on both of the nozzles (5, 6), and said nozzles (5, 6) are positioned at the correct distance in relation to the surface (37, 38) of the glass pane (2).

摘要:
A foldable plastic tail or rear window shield for a car top or hood comprises a polyurethane monolayer. It is produced by pouring or casting a reaction mixture onto a planar casting or pouring substrate. The reaction mixture contains a bifunctional hydroxyl group-containing polyester, a trifunctional polyol, a polyisocyanate from a cycloaliphatic isocyanate urea adduct dissolved in a isophorone diisocyanate and optionally a bifunctional isophorone diisocyanate.
