Self-heating tape casting processing system for the production of thin-sheet ceramics

Abstract

The invention discloses a self-heating tape casting processing system for the production of sheet ceramics, which comprises a frame, a base belt, a conveyor belt, a feed box, a scraper and a heat drying cover, the conveyor belt can drive the base belt to feed, and the feed box is used to hold ceramic raw materials Slurry, the slurry flows out from the discharge port of the feed box, the base belt drives the slurry to feed, the scraper scrapes the slurry to form sheet ceramics, and the heat drying cover is used for drying ceramics, which is used for the production of sheet ceramics in the present invention. Conductors are set inside the baseband of the self-heating casting processing system. By setting the shaking magnetic field and drying magnetic field, the slurry can be defoamed again at the front end of the scraper, and the air bubbles in the slurry can be further discharged; at the same time, when drying, the upper and lower parts of the sheet ceramics are simultaneously When heated, the water in the lower part of the ceramic evaporates early, reducing the impact of the later evaporation of the water in the lower part of the ceramic on the upper surface of the semi-dry ceramic, improving the surface quality of the ceramic, and the baseband can be recycled, with a simple structure and great application value.

Description

technical field [0001] The invention relates to the technical field of ceramic processing equipment, in particular to a self-heating tape-casting processing system for the production of sheet ceramics. Background technique [0002] Tape casting is a molding method for ceramic products, especially suitable for forming sheet ceramic products with a thickness of 0.2MM--3MM. The specific process includes: firstly, mix the pulverized powder and the organic plasticizer solution according to an appropriate ratio to make a slurry with a certain viscosity, and the slurry flows down from the container together, and is scraped and coated on the special surface with a certain thickness by a scraper. On the base belt, after drying and curing, peel off the film that becomes the green belt, and then according to the size and shape of the finished product, the green belt needs to be punched, laminated, etc. to make a blank product to be sintered. In tape casting equipment, the heat source ...

AI Technical Summary

Problems solved by technology

In tape casting equipment, the heat source for drying treatment is generally located above the sheet-shaped ceramics, causing the water above the ceramics to be discharged earlier than the water below the ceramics, and the water discharged after the lower part of the ceramics is easy to make the upper surface of the ceramics in a semi-dry state Quality defects appear, and the discharge effect is not good, which will affect the internal and external quality of the ceramic; and if the air bubbles in the slurry cannot be discharged as much as possible, the quality of the ceramic will be affected during the drying and sintering process
