  Float glass production process

  The process of forming the float glass is done in the tin bath into the protective gas (N2 and H2). The molten glass flows continuously from the kiln and floats on the surface of the tin liquid with relatively large density. Under the action of gravity and surface tension, the molten glass is spread on the tin liquid surface and flattened to form the upper and lower surfaces, harden and cool After being cited as a transition roll table. Roller table roller rotation, the glass out of the tin into the annealing furnace into the furnace, the annealing, cutting, to get flat glass products. Float and other molding methods, the advantages are: suitable for high-quality manufacturing of high quality flat glass, such as no wave tendons, uniform thickness, the upper and lower surface smooth, parallel to each other; the scale of the production line is not limited by the forming method, Low cost; high utilization of finished products; easy scientific management and full mechanization, automation, high labor productivity; continuous operation cycle can be up to several years, is conducive to stable production; for the production of some new varieties to provide suitable conditions, such as Electric float glass, annealing glass coating, cold end surface treatment.

  Single-chip float glass sound insulation performance is poor, the merits of its performance according to GB / T8485-2002 "building outside the window air insulation performance classification and testing methods" and GBJ75-1984 "building noise measurement specifications", and with reference to the international Standard ISO140 and ISO717 on the sound insulation performance of the identification, the use of weighted sound insulation Rw to measure sound insulation performance indicators, the unit is dB; another sound insulation performance indicators STC can be used as a reference index.
