The present disclosure provides a production method for laminated glass. The production method includes the following steps: loading laminated glass into a vacuum inlet chamber, evacuating to a first vacuum pressure, and transferring the glass at a high speed; transferring the glass to a vacuum inlet buffer chamber, and evacuating to a second vacuum pressure; transferring the glass to a vacuum inlet transfer chamber, reducing the transfer speed for low-speed transfer, and evacuating to a third vacuum pressure; transferring the glass to a vacuum heating chamber, maintaining a third vacuum pressure, and heating; transferring the glass to a vacuum cooling chamber, maintaining a third vacuum pressure, and cooling; transferring the glass to a vacuum outlet transfer chamber, maintaining a third vacuum pressure, and increasing the transfer speed for high-speed transfer; transferring the glass to a vacuum outlet buffer chamber, and dropping a vacuum pressure to a second vacuum pressure; transferring the glass to a vacuum outlet chamber, dropping a vacuum pressure to a first vacuum pressure, and outputting finished laminated glass. The laminated glass produced by the present disclosure has a high yield and low energy consumption.

The present disclosure provides continuous vacuum production equipment for laminated glass. The production equipment includes a vacuum inlet chamber, a vacuum inlet buffer chamber, a vacuum inlet transfer chamber, a vacuum heating chamber, a vacuum cooling chamber, a vacuum outlet transfer chamber, a vacuum outlet buffer chamber and a vacuum outlet chamber, which are sequentially connected. A valve is provided between every two adjacent chambers to control communication of the two adjacent chambers. The laminated glass produced by the present disclosure has a high yield and low energy consumption. Compared with a traditional production line includes two independent processes, the present disclosure increases the production efficiency for tens to hundreds of times. In addition, the present disclosure has a wide application range, and it is suitable for flat, single-curved and multi-curved laminated glass.

A method for producing a multi-layered wet friction material includes providing a bottom layer, providing a top layer produced independently of the bottom layer from different materials, and bonding the bottom layer to the top layer. The bottom layer and the top layer may be produced from different formulations and supplied as raw papers. A formulation of the top layer may include twenty to sixty percent (20%-60%) filler, ten to forty percent (10%-40%) wood pulp, five to ten percent (5%-10%) aramid, and twenty-five to thirty-five percent (25%-35%) phenolic resin. A formulation of the bottom layer may include ten to fifty percent (10%-50%) filler, ten to forty percent (10%-40%) wood pulp, five to ten percent (5%-10%) aramid, five to fifteen percent (5%-15%) carbon, and twenty-five to thirty-five percent (25%-35%) phenolic resin.

In a production apparatus, a pass line for conveying a film is formed in parts of both belts wound on common rolls and in contact with each other across the film, a discharge port of a discharger is so provided that the molten resin reaches one first roll, out of a group of first rolls, on a side upstream of the pass line, and the common rolls include a cooling roll for cooling and solidifying the molten resin discharged from the discharge port and having reached the first roll.

A film-laminated metal plate having excellent retort adhesiveness includes: a metal plate; a resin film thermally fusion-bonded to a surface of the metal plate; and a bubble contained between the metal plate and the resin film. An average bubble height of three bubbles with higher heights among the bubbles measured by using a 3D analysis image of a laser microscope is 0 μm or more and 5.0 μm or less. The test piece is obtained by cutting a portion of one end side of the metal plate in a longitudinal direction while leaving the resin film on a side which becomes an inner surface side of the container when the film-laminated metal plate is processed into a container. When a retort treatment is carried out on the test piece at a temperature of 125° C. for 30 minutes in a state in which a 100 g weight is hung from the one end side of the test piece and the test piece is folded back toward the other end side of the test piece in the longitudinal direction by 180°, a length of the resin film peeled off from the metal plate of the test piece is 15 mm or less.
