Description
Technical Field
The invention belongs to the technical field of hollow glass parting strip production, and particularly relates to an injection molding production line for a hollow glass warm edge parting strip.
Background
The common single-layer glass plays the roles of lighting, ventilation and vision field expansion when being applied to buildings, but the heat-insulating property is poor; the double glazing effectively solves the problem of single glazing in terms of heat insulation performance, but the double glazing easily absorbs water vapor and the like in the air to form dew, thereby affecting the visual field. The hollow glass is made by sealing two pieces of glass by the sealant through the aluminum parting strips, so that the defects of poor heat insulation and quick heat dissipation of single-layer glass are overcome, the heat insulation advantages of double-layer glass can be reasonably utilized, and the hollow glass has good heat insulation performance.
The division bar in the hollow glass is mainly used for controlling the distance between the inner glass and the outer glass, and controlling the external water vapor to be completely isolated at the part, so that the hollow glass is ensured to have reasonable space thickness and service life. From the perspective of thermal conductivity, the division bars used by the hollow glass can be divided into two categories, namely a cold side and a warm side, wherein the cold side refers to a traditional metal aluminum frame, the warm side refers to a division bar made of a material or different from the traditional aluminum division bar in structure, the division bar aims at improving the thermal conductivity of the edge of the hollow glass, and the energy-saving effect of the window is realized by adopting a small amount of metal or a complete non-metal material or changing the structure of the traditional aluminum bar. Most of the division bars used in China at present belong to aluminum division bars in cold edges, condensation or frost is easily caused at the edges, the energy-saving effect of the whole window is reduced, and the share of the warm edge division bars in the hollow glass market in China gradually rises along with the continuous improvement of the energy-saving consciousness of people.
The warm edge division bar is a composite material product, and the co-extrusion process is the simplest and easiest method for processing the composite material product, so that the co-extrusion process can be applied to the processing of the warm edge division bar. According to different molding states of co-extrusion materials, a co-extrusion process can be divided into front co-extrusion and rear co-extrusion, wherein the front co-extrusion means that two materials are not molded before the co-extrusion, and the two materials are simultaneously subjected to composite molding in the extrusion process; the post-coextrusion refers to the process of realizing composite molding by coextrusion and another material after one material is completely molded before coextrusion, and the coextrusion process can be divided into organic coextrusion and inorganic coextrusion according to the difference of the materials of the extruded materials. At present, the research of China in the field of warm edge division bar injection molding production is less, and a novel injection molding production line is urgently needed in the market to improve the processing efficiency of the warm edge division bar.
