Description of drawings
Fig. 1 for photovoltaic layer press of the present invention with one preferred embodiment of wide cut overlength rubber slab production technology process frame chart.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, according to the invention be a kind of photovoltaic layer press with wide cut overlength rubber slab production technology, its practical implementation step is following:
1, extrude the compressing tablet step: be ready to mixing adhesive tape, start extrude, the compressing tablet production line, in the hopper of extruder, supply adhesive tape; Head temperature is controlled at 60 ℃～90 ℃, and rotating speed is controlled at 300～600 commentaries on classics/min, debugging extruder L type head; The slice THICKNESS CONTROL is at 3.9～4.0 millimeters, and film is sent into the tablet press machine of the good roll spacing of adjusted, and THICKNESS CONTROL is at 3.8～4.0 millimeters; Width is controlled at 1.1～1.2 meters; Through chill roll and the devices for taking-up of being furnished with shield, rolling on spool becomes coil diameter to be controlled at 400～800 millimeters.
2, wide cut uncured rubber sheet metal forming: with the handling of uncured rubber coiled sheet, be placed on the unwinding equipment fixed mount, derive, severing uncured rubber plate, two width of cloth uncured rubber plates are overlapped; Seam is transferred under the hot pressing device; Controlled pressure is at 3～5Mpa, and 70～80 ℃ of hot pressing temperature controls start hot pressing device; With the seam pressing, the control time was at 3～6 minutes.The 3rd width of cloth uncured rubber plate is pieced together the width of cloth, pressing with second after the same method.
3, the sulfuration process of wide cut offset plate: (1) preparatory process: will descend the two ends of rubber rim strip to be installed in respectively on the devices for taking-up of large plate vulcanizer both sides, the two ends of last rubber rim strip are fixed on the last hot plate of large plate vulcanizer, and give rim strip tension force with adjusting device; Pressure is 3Mpa～5Mpa; Preferred pressure is 3.5～4Mpa, starts the cooling system of heating system and hot plate salband, and the hot plate temperature at salband position is controlled at 70 ℃～90 ℃; Hot plate temperature is 141 ℃～185 ℃; Preferred 150 ℃～175 ℃, when hot plate temperature reaches the regulation requirement, wide cut uncured rubber plate is shifted and smooth being layered on the rubber rim strip with conveyer belt; Start devices for taking-up; The uncured rubber plate in the holder of rubber rim strip, moves to up and down between the hot plate of large plate vulcanizer accurately, and each plate hot-press vulcanization time is 20～30 minutes.
(2) vulcanization process: the one plate continuous vulcanization of large plate vulcanizer one plate is adopted in the sulfuration of offset plate; Guarantee that through the filler strip that is fixed on the hot plate both sides thickness after the offset plate sulfuration meets the product specification requirement; Cooling effect through salband on the hot plate; After making last plate hot-press vulcanization, offset plate rearward end (about 300 mm wides) does not cure, and next plate places rearward end state of cure (vulcanization) insufficient section in the hot plate cure range; Reach the linking hot-press vulcanization of a plate one plate, guarantee that the state of cure (vulcanization) of offset plate junction is consistent with other position with sole thickness; During the offset plate sulfuration, rim strip contacts with the upper and lower surfaces of offset plate up and down, through the scavenging action of the fine and smooth woven design of rim strip upper surface, makes air and the volatilization gas of sizing material generation when high temperature vulcanized, under high pressure cloth textured being excluded in edge between offset plate and the rim strip; Through the elasticity of rubber rim strip in hot-press vulcanization, guarantee the homogeneous of offset plate sulfide stress; Thereby the high density of processing, surfacing also have the rubber slab of woven design.
4, the post vulcanization of offset plate is used large-scale Electric heat oven, and offset plate is positioned over baking oven with hang, and temperature is 141 ℃～185 ℃, and preferred temperature is 150 ℃～175 ℃, and the time is 2～6 hours.
According to the invention is that a kind of photovoltaic layer press is with wide cut overlength rubber slab production technology; The offset plate that this explained hereafter goes out is high temperature resistant, long service life, integral seamless; And closely knit, the no bubble of offset plate, good, the good physical and chemical of air-tightness, this product has good market prospects.
