摘要:
An electrode plate (20) for storage batteries is immersed into an aqueous solution (18) containing phosphoric acid, an ethoxy alcohol, ammonium bifluoride, sulfonic acid and sodium xylenesulfonate, and the aqueous solution (18) is stirred by a screw stirrer (22). The aqueous solution (18) is kept at about 30° C. by a heater (14), and the active material of the electrode (20) is separated therefrom. The aqueous solution (18) contains the respective solutes in the following mass ratios: 15-20 parts by mass of the phosphoric acid; 3-7 parts by mass of the ethoxy alcohol; 2-6 parts by mass of the ammonium bifluoride; 4-8 parts by mass of the sulfonic acid; and 1-3 parts by mass of the sodium xylenesulfonate.

A method for partially treating a water-repellent glass sheet is disclosed which comprises irradiating part of a water-repellent glass film, formed on the water-repellent glass sheet, with a stream of plasma jets generated by a plasma jet irradiating gun. By such plasma jet irradiation, the film part can be removed easily even when the glass sheet has a curved surface.
摘要:
A roll-forming unit of a curved glass manufacturing apparatus includes a cooperating pair of upper and lower forming roll mechanisms. Each mechanism includes a forming roll having a resilient rod covered with a cover member except opposite end portions thereof, a pair of support members rotatably supporting the opposite end portions of the resilient rod while allowing the resilient rod to tilt about said support members, a bending unit coupled with at least one of the opposite end portions of the resilient rod for applying to the one end portion an external force tending to flex the forming roll into either an upwardly arched configuration or a downwardly arched configuration, and at least one backup roller unit being in rolling engagement with the forming roll to maintain the arched configuration of the forming roll. The roll-forming unit of the foregoing construction is able to bend a heated flat glass sheet into a desired curvature without producing a slip between forming rolls and the glass sheet and is readily adaptable to the manufacture of various batches of curved glass sheets of different curvatures. A conveyor roll mechanism particularly suitable for use in combination with the roll-forming unit is also disclosed.

There are provided an interlayer film separation solution and an interlayer film separation method capable of separating an interlayer film and a glass for a short period of time and collecting the separated interlayer film in a recyclable condition. An interlayer film separation solution 21 having etching ability for a glass is introduced into a container 22, and the introduced interlayer film separation solution 21 was controlled to a temperature of 30 to 60° C., and a laminated glass 10 with glass plates 11, 12 crushed is introduced into a barrel 23 from a lid portion 23a, and simultaneously, 50 to 60 metal pieces 25 are, introduced into the barrel 23 from the lid portion 23a in order to easily separate the laminated glass 10 into the glass plates 11, 12 and an interlayer film 13. The barrel 23 containing the laminated glass 10 and the metal pieces 25 introduced thereinto is rotated at a predetermined rotational speed.
