Use of a mixture of flour and konjak welan gum, as a binder for the ceramic and powder-metallurgical shaping

摘要

The present invention relates to the use of a mixture of flour and konjak welan gum, as a binder for the ceramic and powder-metallurgical shaping. In the case of the shaping inorganic particle size can be made of oxidic, not - oxide ceramics, carbon and / or metallic grain sizes are. The particle sizes of the raw materials used of the inorganic particle size are in the range from 50 nm to 10 mm. The binders used according to the invention is particularly suitable for the conventional slip, for the pressure slip casting, for the casting of vibration masses and self-flowing masses, as a binder in the case of flexible masses, in the extrusion, in the form of a binder for the production of thin-walled products by means of the tape casting and of the paper technology, and also as a binder in the production of granulated material in the case of the press shaping. It is an object of the invention, it is, an environmentally friendly binder for the ceramic and powder-metallurgical shaping of the invention to develop to a higher green mechanical strength of the shaped elements and, in the case of the demolding to high-quality surfaces.According to the invention, the problem is solved in that a mixture of konjak flour and welan gum, as a binder for the ceramic and powder-metallurgical shaping is used.
