Embodiment Construction

[0012] The present invention is described in detail below with reference to accompanying drawing:

[0013] The invention adopts a coupled control precision extrusion process. It divides the content of precision extrusion into two systems: flow system and size system, and adopts dual system coupling to meet the requirements of stability and precision. The flow system achieves the stability of the extrusion flow on the basis of improving the barrel screw temperature control, screw speed control and traction speed control level, rationally designing the screw structure of the extruder, and optimizing the flow rate of the extruder head. The size system adopts The controllable multi-point primary cold sizing and multi-point secondary thermal sizing coupling approach size can obtain high-precision size of extruded products. In the dual system coupling method of the flow system and the size system, the temperature of the barrel screw, the screw speed and the traction speed are incre...

Abstract

The invention relates to a thermal and strengthened insulating glass spacer bar, relating to a building material product. The spacer bar is prepared by adopting coupled control precision extrusion molding process, which adds a warm edge spacer bar (1) of organic composite material made from fiberglass into Nylon 66; the coupled control precision extrusion molding process is as follows: a flow system and a size system are adopted and coupled, wherein the flow system is realized by improving the screw temperature of a machine barrel, screw rotary speed and towed speed; and the size system is completed by the coupled size of multipoint primary cold sizing and multipoint secondary cold sizing. The material used in the invention is completely organic composite material which has good mechanical strength, low thermal coefficient and linear expansion coefficient with no pollution and high product cost performance. The adoption of coupled control precision extrusion molding process has the advantages of high processing precision, simple processing process and low cost. When in use, the warm edge spacer bar (1) can be clamped between two glass sheets (3).

Description

technical field [0001] The invention relates to a building material product, in particular to a hollow glass spacer used on building doors and windows. Background technique [0002] With the gradual improvement of people's awareness of energy saving, especially the rapid growth of global energy prices in the past year and the intensification of global warming, as well as people's awareness of energy saving and the continuous improvement of the utilization rate of insulating glass, the reduction of energy consumption is becoming more and more important. more and more people's attention. [0003] At present, most foreign countries produce warm edge spacers, such as super spacers, Technostyle spacers, etc. Their processing technology mostly adopts extrusion compounding or extrusion molding technology, which are relatively complicated, which increases the cost and makes the spacer bar expensive. In China, the cold edge spacer-aluminum alloy spacer is still the main one. The a...
