Background technology
Traditional XPS extruded plastic foam warming plate production line is to use fluorine series blowing agent and chain hydrocarbon.As everyone knows, freon is the main cause that causes ozone hole, uses freon to be unfavorable for environmental protection, by international community is forbidden; And chain hydrocarbon has inflammability, influences production safety.
At present; The XPS plastic extrusion heated board that in the production of extruded plastic foam warming plate, has used carbon dioxide foaming agent to produce; But; Existing carbon dioxide foaming agent in injection process, gets into the carbon dioxide of body and the melt resolution is low, diffusance is high, cause and be difficult to mixing or mixing inhomogeneously with melt, and causing can't the ordinary production qualified product.And the boiling point of carbon dioxide is-78 ℃, in injection process, receives the influence of environment temperature and transient pressure, is prone to cause gasification or knot dry ice, causes carbon dioxide can not stablize injection, can't reach the purpose of smooth foaming.The insulation extruded sheet unit weight for building that the most generally uses according to national requirements requires 30kg/m
3More than, below the thermal conductivity factor 0.030w/mk, still, existing titanium dioxide carbon foaming extruded sheet just adds the use amount of carbon dioxide with reduction freon in freon, or the simple ethanol that adds is as auxiliary agent in carbon dioxide.The product unit weight of being produced is all at 36kg/m
3More than, cause the raw materials for production cost to increase by 20%; Thermal conductivity factor is greater than 0.030w/mk, and heat-insulating property can not be up to state standards fully, and this is that the technical staff knows together in the present technique field.
Summary of the invention
The purpose of the utility model is to solve the problem that prior art exists, and provides a kind of carbon dioxide foaming agent to inject the production foaming extruded sheet stable, that expansion ratio is high with modification carbon dioxide injected system.
For addressing the above problem, the utility model adopts following technical scheme:
A kind of production foaming extruded sheet is with modification carbon dioxide injected system; Comprise carbon dioxide fluid reservoir, measuring pump, vacuum tank; The liquid outlet that it is characterized in that the carbon dioxide fluid reservoir links to each other with the inlet of CO 2 high pressure delivery pump; The liquid outlet of CO 2 high pressure delivery pump links to each other with the carbon dioxide vacuum tank through pipeline; The inlet of CO 2 high pressure measuring pump links to each other with the carbon dioxide vacuum tank through pipeline, and the liquid outlet of CO 2 high pressure measuring pump links to each other with the high pressure mixing device through pipeline; The inlet of promoter voltage stabilizing measuring pump links to each other with the promoter fluid reservoir through pipeline; The liquid outlet of promoter voltage stabilizing measuring pump links to each other with the inlet of promoter high-pressure metering pump through pipeline, and the liquid outlet of the promoter high-pressure metering pump pipeline that was connected links to each other with the high pressure mixing device; The liquid outlet of high pressure mixing device links to each other with extruder through pipeline, on high pressure mixing device and pipeline that extruder links to each other, check valve is installed.
On the liquid outlet of above-mentioned promoter voltage stabilizing measuring pump and the pipeline between the promoter high-pressure metering pump, stable-pressure device is installed.
On the liquid outlet of above-mentioned CO 2 high pressure measuring pump and the pipeline that the high pressure mixing device links to each other the carbon dioxide check valve is installed.
On the liquid outlet of above-mentioned promoter high-pressure metering pump and the pipeline that the high pressure mixing device links to each other the promoter check valve is installed.
The characteristics of the utility model are following: 1, with liquid carbon dioxide with after promoter is mixed in the high pressure mixing device; Inject extruder; Solve carbon dioxide problems such as physical aspect is unstable in injection process, expansion ratio is on the low side, also goods unit weight has been reduced to 32 kg/m
3Or below, thermal conductivity factor is reduced to below the 0.028w/mk, thereby improves the combination property of extruded sheet goods greatly, reaches or is superior to national standard.2, adopt voltage stabilizing measuring pump and high-pressure metering pump with accurately quantitative being transported in the extruder system of form with liquid state of blowing agent carbon dioxide and promoter, thereby make extruded sheet goods distribution of cells uniform and delicate, the product properties index all reaches the GB requirement.3, this system has characteristics such as structure configuration is reasonable, easy to use.
