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
The present invention relates to a kind of building materials, particularly a kind of hollow glass spacer bar that is used on the building doors and windows.
Background technology
Along with the progressively raising of people to energy-conservation understanding, particularly global energy prices growth at full speed and the growing in intensity of global warming in the previous year, and people's awareness of saving energy and to the improving constantly of hollow glass utilization rate, reduce energy consumption and more and more be subjected to people's attention.
At present, the external warm limit spacer bars of producing as super spacer bar, taino spacer bar etc. more.Their processing technology adopts the compound or extrusion forming technology of extruding more, and is all complicated, improved cost, causes spacer bar to cost an arm and a leg.Domestic still based on cold limit spacer bar---aluminium alloys spacer bar.The aluminium alloys spacer bar is cheap, and processing technology is simple, and the heat-proof quality difference is its maximum shortcoming, makes the energy consumption of heating installation, air-conditioning increase greatly.
Summary of the invention
The object of the present invention is to provide a kind of hollow glass spacer bar that is used on the building doors and windows.This spacer bar thermal conductivity is little, and linear expansion coefficient is low, and processing technology is simple, and cost is low, has very high cost performance, and has solved the cold limit problem of hollow glass, can further improve the energy-conservation level of hollow glass.
The objective of the invention is to be achieved through the following technical solutions:
The hollow glass spacer bar of can be warming, strengthening, this hollow glass spacer bar adopt coupled control precision extrusion molding process to make, and are the warm limit spacer bars that adds the organic composite material that glass fiber makes in nylon 66; Coupled control precision extrusion molding process is: adopt the coupling of flow system and size system dual system, wherein flow system is: improve screw barrel temperature, screw speed and traction towed speed and realize; Size system is that the coupling size of cool sizing of multiple spot and multiple spot secondary hot size is finished.
The described hollow glass spacer bar of can be warming, strengthening is characterized in that, is provided with the rib of one " V " font in spacer bar inside.
Advantage of the present invention and effect are:
1. material therefor of the present invention is complete organic composite material, has excellent mechanical intensity; Thermal conductivity is low, and linear expansion coefficient is low, and is pollution-free, and product has very high cost performance.
2. the present invention adopts coupled control precision extrusion molding process, and machining accuracy height, processing technology are simple, with low cost.
Description of drawings
Accompanying drawing of the present invention is the product structure schematic diagram.
The specific embodiment
The present invention is described in detail with reference to the accompanying drawings:
The present invention adopts the coupled control precision expressing technique.The content that it extrudes precision is divided into dual system: flow system and size system, adopt the dual system coupling to reach stable and accurate requirement.Flow system passes through with on the basis of improving the control of screw barrel temperature, screw speed control and traction towed speed controlling grade, appropriate design extruder screw rod structure, optimization extruder head flow, realize the stability of Extrusion Flow, size system adopts the coupling of cool sizing of controllable multiple spot and multiple spot secondary hot size to approach size, obtains the high-accuracy size of extruded product.Adopt raising screw barrel temperature, screw speed and traction towed speed in flow system and the size system dual system coupling process; The coupling size of cool sizing of the multiple spot of size system and multiple spot secondary hot size is conventional expressing technique apolegamy parameter.As: the solid phase of control machine barrel extruder temperature and material is stopped up, and reduces the intermediate frequency fluctuation, realizes the accurate plasticizing of extruded segment, and melt zone is stablized fusion, metering section is stable carries.Improve the temperature and the rotating speed controlling grade of extruder, it is very responsive to the fluctuation of temperature and motor speed that system extrudes flow rate, adopt PLC programmable logic controller and Industrial Personal Computer (IPC) etc. to realize the closed-loop control of extrusion, the fluctuation of extrusion temperature is controlled at ± 0.5 ℃ in, the stability of motor speed is controlled at 0.01%.The towing stability of draw-gear, draw-gear adopt variable-frequency motor, realize closed-loop control with extruder.Because the viscoplasticity of high polymer makes the response of strain counter stress have hysteresis quality, has caused the difficulty of accurate control.Therefore, when fluctuation took place the extruder flow rate, it was more reasonable than changing screw speed to change hauling speed, and control accuracy is higher.On-line testing method, opto-electronic conversion test and seamless detection method are requisite during for the detection of realization extruded product precise measure and on-line measurement.Test the performance gap and the material internal homogenization of accurate extruded product and conventional extruded product.Can control in the technology of cool sizing of multiple spot and secondary hot size, adopt cool sizing vacuum controlling dimension lower deviation that outwards expands, the secondary hot size inwardly pressurizes and shrinks the controlling dimension upper deviation, two ends are approached, near optimum value (promptly separately the goods minimum dimension by a vacuum cool sizing all greater than the upper deviation, and be to approach lower deviation by the maximum size of the goods behind the secondary hot size).Simultaneously, the force value of vacuum size that online size detection can a cool sizing of closed-loop control and secondary hot size reaches the purpose of online adjustment.
The present invention adds glass fiber in organic composite material nylon 66, the organic warm limit spacer bar that adopts extrusion technology to process; The glass fiber amount that in nylon 66, adds, but apparent intensity, hardness need and decide.Thermal conductivity is about 1/800 of aluminium alloys; Linear expansion coefficient and aluminium alloys are at the same order of magnitude.On the structure of spacer bar, cast aside the design concept of the complete hollow of traditional spacer bar, portion adds the rib 2 of " V " font within it, strengthens its mechanical strength.During use, warm limit spacer bar 1 is sandwiched between two glass plates 3, and flat getting final product installed on this trapezoidal base of hollow glass spacer bar and two glass plates, 3 limits.
