Description

A kind of EVA glued membrane extruder
Technical field
The utility model relates to a kind of EVA production equipment, is specifically related to a kind of EVA glued membrane extruder.
Background technology
If solar cell is directly exposed in air, its photoelectric transformation efficiency can decline very soon, loses practical value.Therefore, the research and development of the encapsulation material of solar cell are just very important.For reaching the object being isolated from the outside; adopt transparent, light aging resisting, adhesive property good, can bear atmosphere and change and there is flexible ethylene-vinyl acetate copolymer (EVA) glued membrane solar battery sheet is sealed; and be bonded together with levels protective material, form solar module.
EVA is a kind of typical random macromolecular compound, in its molecular structure, the irregular arrangement of substituting group on strand, in strand, the configuration of asymmetric carbon atom is not identical yet simultaneously, arrange also irregular, therefore it be that a kind of crystallinity is less, polarity and the higher material of pliability, it has good wellability in the time of heating and melting in addition, when cooling curing, having good flexibility, anti-stress cracking and adhesive property, is a kind of comparatively desirable material that can be used for solar cell package.
What EVA film forming adopted is extrusion forming process, and whole production line generally includes mixing plant, extrusion equipment, film pressing device, trimming unit and retractable volume equipment, completes batch mixing, material loading, extrudes, calendering, trimming, winding process.Determine will have of end product quality: raw material and formula, hot-melt extrusion process, and the several aspects of casting molding processes control, and in casting molding processes process, environment temperature and humidity is also an important step, suitable humidity and stable temperature, can reduce the stretcher strain of film, the tension force of controlling diaphragm.
At present, in EVA production process EVA micelle in water back by the colloid of melt into molten condition.Water back, normally by electrical heating, easily forms heat build-up in electrical heating, is difficult for temperature to control the quality that all can affect EVA glued membrane too high or too low for temperature.
Utility model content
The technical problems to be solved in the utility model is: propose a kind of EVA glued membrane extruder that can immediately regulate EVA melten gel temperature in water back fast.
The utility model is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of EVA glued membrane extruder, mainly formed by water back and the extruder that is located at described water back end, also comprise water knockout drum, described water back is to be made up of cover cylinder and the auger conveyor being located in described cover cylinder, the central shaft axle of described auger conveyor is filled with cooling fluid, described outer cup cylinder spaced surface is provided with multiple heating-cooling units, in each described heating-cooling unit, have and be close to the heating wire of described cover tube outer surface and be tightly placed in the outside cooling tube of described cover cylinder, described heating wire and cooling tube are set up in parallel successively, the circulation two ends of described cooling tube are connected to water knockout drum, between total inlet of described water knockout drum and total liquid outlet, be provided with circulating pump and heat-exchanger rig.
Further, also comprise controller and the glued membrane X-ray calibrator that is arranged on described extruder glued membrane exit, the signal output part of described glued membrane X-ray calibrator is connected to described controller, and the control end of described controller is connected to the controlled end of described heating wire and described circulating pump.
Further, described heating-cooling unit is 9, and described circulating pump is for there being brush DC water pump.
The beneficial effects of the utility model are:
Extruder in the utility model is filled with outside cooling fluid in screw conveyor shaft also has multiple heating-cooling units in water back disposed outside, the aforementioned unit of opening and closing selectively, makes the temperature control in heating tube more subtilized and linear.Thereby make the quality of the EVA glued membrane of producing more stable, reduced defect rate.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, EVA glued membrane extruder of the present utility model is described further.
Fig. 1 is the structural representation of EVA glued membrane extruder in the utility model.
Fig. 2 is the end construction schematic diagram of EVA glued membrane extruder in the utility model.
