Ceramic raw material degumming agent capable of changing mobility of ceramic raw material and preparation method thereof

Abstract

The invention relates to a ceramic raw material degumming agent and a preparation method thereof, in particular to a ceramic raw material degumming agent capable of changing the mobility of a ceramicraw material and a preparation method thereof. When the degumming agent is added into ceramic raw material waste, because the degumming agent contains sodium polyacrylate, the degumming agent can be attached to the surface of mineral particles, so that the mineral particles do not rub each other, which causes no fluidity, and the friction is reduced so that the ceramic raw material with no flow rate is changed into the ceramic raw material with a flow rate, from an energy point of view, the surface energy of the mineral particles can be reduced, thereby reducing the grinding energy and improving the grinding efficiency. The sodium tripolyphosphate in the degumming agent can react with cations in the ceramic raw material to form an insoluble salt, thereby achieving the purpose of scale inhibition and simplifying the recycling of the ceramic raw material. The invention also provides a preparation method of the degumming agent, the method is simple and convenient to operate and greatly improves the production efficiency of the degumming agent.

Problems solved by technology

In ceramic production, the water content of mud is generally 33%-36%, but at such a high water content, the fluidity of mud containing clay minerals will still be poor

When the viscosity of the mud is too high, the fluidity is poor, and the slurry eating speed is too fast, and the mud flowing into the model will cause uneven thickness of the green body and uneven slurry surface, and it will not flow completely when the slurry is discharged, and it is easy to produce defects such as cracks when drying. , causing great difficulties to production, especially forming

Moreover, the waste of ceramic raw materials is often discarded directly due to their lack of fluidity, which intensifies the consumption of ceramic raw materials and prevents effective use of high-quality raw materials. It will inevitably bring a series of problems such as dust pollution, smoke pollution, water pollution, etc. Therefore, a suitable ceramic debonding agent is developed and prepared, so that the ceramic raw material without flow rate becomes the ceramic raw material with flow rate, and the ceramic raw material with flow rate flows faster , while reducing the moisture content of ceramic raw materials, it becomes extremely important
