Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described, and protection scope of the present invention is not limited to the following stated:
A kind of half aluminum plating glass microballon production technology, is coated with 1/2nd aluminium coated on glass microballoon surface, it comprises the following steps:
S1: plant pearl operation: on coating machine, plant glue is applied on PET film corona face, dries, then glass microballoon is evenly distributed in and plants on pearl glue, rolling, obtains beads formed film.
S2: vacuum aluminum-coated operation: the bead planted film that step 1 is obtained is put into vacuum aluminum-plating machine and aluminized, aluminum layer thickness is controlled at 300-1000 dust, obtains the bead planted film of aluminizing.
S3: brush pearl operation: the beads formed film of aluminizing that step 2 is obtained unreels on brush pearl device by the brush roll 7 running up, from glue-line the inside brush from getting off, installs a frication 11 glass microballoon below brush roll 7, collects and obtains half aluminum plating glass microballon
Described step 2 is when vacuum aluminum-coated, first diffusion pump and booster pump heating about one hour, when oil temperature reaches 240 DEG C of left and right, start slide valve pump, open and slightly take out valve, vacuum chamber is slightly taken out, open deep cooling and general cold, open the refrigerator of diffusion pump, in the time that vacuum reaches 500Pa, open lobe pump, in the time that vacuum reaches 3Pa, first close and slightly take out valve, open front step valve, essence is taken out valve again, to vacuum chamber pumping high vacuum, after vacuumizing, and then slow heating evaporation boat, when evaporation boat temperature reaches 1200-1400 DEG C, start to send aluminium wire.
As shown in Figure 1, a kind of half aluminum plating glass microballon brush pearl device, it comprises frame 12, from left to right, described frame 12 lefts are provided with a unwinding rack 1, the right-hand rolling frame 2 that is provided with of described frame 12, described frame 12 is divided into two-layer up and down, the traction electric machine 3 that described frame 12 upper stratas are provided with draw-gear and drive draw-gear to rotate, described traction electric machine 3 left and right sides are provided with a draw-gear, on described frame 12 lower floor's upper surfaces, be provided with drive motors 4, brush roll 7, idler roller 8 and tensioning apparatus 10, described drive motors 4 left and right two sides are provided with a brush roll 7, the right side of each brush roll 7 is provided with an idler roller 8, idler roller 8 is connected with tensioning apparatus 10, by regulating tensioning apparatus 10 to regulate the position of idler roller 8, to guarantee that beads formed film fully contacts with brush roll 7, improve the brush pearl efficiency of brush roll 7, described drive motors 4 drives brush roll 7 to rotate, each described brush roll 7 below correspondence are provided with a frication 11, on frication 11, be connected with an anti-plate 13 that flies upward, prevent that flying upward plate 13 is connected with frame 12.
In the present embodiment, draw-gear comprises initiatively carry-over pinch rolls 5, driven carry-over pinch rolls 6 and support 14, described active carry-over pinch rolls 5 are arranged on frame 12 upper strata upper surfaces, described driven carry-over pinch rolls 6 are positioned at initiatively carry-over pinch rolls 5 tops, and be arranged on frame 12 tops by support 14, driven carry-over pinch rolls 6 are on support 14, can move up and down, described support 14 is fixedly connected with frame 12, when initiatively carry-over pinch rolls 5 draw beads formed film, can regulate the distance of driven carry-over pinch rolls 6 and active carry-over pinch rolls 5, to ensure the traction dynamics of beads formed film, for further conveniently planting the traction of pearl glued membrane, in frame 12 lower surface, be provided with multiple deflector rolls 9.
Specific embodiment of the invention process is as follows:
S1: wear film, the glass microballoon beads formed film of having aluminized is fixed on material unwinding rack 1, beads formed film is through active carry-over pinch rolls 5 and brush roll 7, while wearing film, glass microballoon face need contact with 7 of brush roll, then through passing through again initiatively carry-over pinch rolls 5 and brush roll 7 after deflector roll 9, and then after deflector roll 9 on rolling frame 2 the useless film of rolling.
S2: open rolling, regulate the tension force of unwinding rack 1 and rolling frame 2, start winding motor and move with the speed of 3 ms/min, depress initiatively carry-over pinch rolls 5 and driven carry-over pinch rolls 6.
S3: start brush roll, open drive motors, start brush roll 7, by regulating tensioning apparatus 10 to regulate idler roller 8, to control the distance of beads formed film and brush roll 7, guarantee to control beads formed film and fully contact with brush roll 7, and the running frequency of brush roll 7 is adjusted to 30HZ, regulate the anti-of frication 11 tops and fly upward plate 13 positions, and fix frication 11.
S4: normally operation, carry out after above adjusting, heighten the rolling speed of service, and the brush of simultaneously observing the collecting effect of frication 11 and the beads formed film upper glass microballon after brush roll 7 is from situation, at the brush that fully ensures half aluminum plating glass microballon from rate, the flexible modulation rolling speed of service, reaches the requirement of efficient collection half aluminum plating glass microballon.
