The invention discloses a
waterfall flow type special jig for chemical
etching and a preparation method of ultrathin glass. The
waterfall flow type special jig comprises a mounting base, a rotating shaft is rotatably connected into the mounting base, a supporting frame is fixedly connected to the front end of the rotating shaft, PVC cover plates are connected to the right ends of the upper side and the lower side of the supporting frame in a clamped mode, supporting rods distributed at equal intervals are fixedly connected to the upper end of the supporting frame, and spraying pipes are mounted at the upper ends of the supporting rods; nozzles distributed at equal intervals are fixedly connected to the right end of the spraying
pipe. According to the
waterfall flow type special jig for chemical
etching and the preparation method of the ultrathin glass, a waterfall flow type chemical
etching method is adopted, no pressure is needed on the glass, the glass cannot be broken due to stress, the
recovery ratio is high, waste liquid is minimum, the
utilization rate of acid liquid is high, a large amount of cost is saved, a conveying belt is used for conveying in the whole process, the apparent effect is good, and
rework is not needed; the yield is very high, turnover operation is not needed, the fragment risk is reduced, the etching capacity is improved, and the sealing performance of the upper end and the lower end of the glass is ensured.
