Deflocculant In Ceramics

Water in the slurry is reduced and the energy consumption of ball milling and spray drying is also reduced.

Deflocculant in ceramics.

Darvan 811 is a deflocculant that is similar to darvan 7 but is more. Water in ceramics water is the most important ceramic material it is present every body glaze or engobe and either the enabler or a participant in almost every ceramic process and phenomena. They are used to improve the viscosity of the clay slip. A slip with a viscosity that is too high is said to be thick.

In addition our product can help make the granular composition of the powdery materials more. In ceramic studios labs and classrooms a good propeller mixer is essential for mixing glaze. In fact what has happened is the electric charges of the clay particles have been rendered neutral by adding an alkaline or basic material to the mix reducing viscosity. The treatment of clay by means of a wet grinding and deflocculation process is a widely used technique by the floor and wall tiles ceramic industry.

Darvan is a liquid deflocculant that is often preferred for use with plaster molds because unlike some other deflocculants darvan does not degrade the plaster. The most efficient compounds having deflocculant action for uses in ceramics are sodium silicate polyphosphates pyro tripoly tetrapoly etc and organic sodium and ammonium polyelectrolytes. By adding a deflocculant it is as if the solution has been made frictionless allowing one to easily mix with minimal water. Our ceramic deflocculant is a kind of stpp replacement for ceramic body.

They are white powder and packed in 25kgs per bag. The technique is important. Thixotropy thixotropy is a property of ceramic slurries. Thus the ceramic production volume is increased.

A deflocculant is used to lower the viscosity of a slip provided of course that the slip does not have so high a solids content that a deflocculant simply cannot thin it any more. Thixotropic suspensions flow when you want them to and then gel after sitting for a few moments. The ceramic deflocculant can reduce the viscosity of the slurry and improve its liquidity. In ceramics there are a number of different deflocculants available.

Following the development of single firing processes the need for atomised clay has led to the use of these processes. There are different varieties of darvan. In ceramic industry glazes are often sprayed especially in sanitary ware.
