Deflocculant In Ceramics

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.

Deflocculant in ceramics.

By adding a deflocculant it is as if the solution has been made frictionless allowing one to easily mix with minimal water. In ceramic industry glazes are often sprayed especially in sanitary ware. They are white powder and packed in 25kgs per bag. 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.

Darvan 811 is a deflocculant that is similar to darvan 7 but is more. 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. A slip with a viscosity that is too high is said to be thick. Thixotropic suspensions flow when you want them to and then gel after sitting for a few moments.

In ceramics this term refers to the flow and gel properties of a glaze or body suspension made from water and mineral powders with possible additives deflocculants modifiers. Thus the ceramic production volume is increased. No single product acts according to all of the mechanisms described above therefore a mixture of various compounds is usually used whose combined. 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.

Our ceramic deflocculant is a kind of stpp replacement for ceramic body. Following the development of single firing processes the need for atomised clay has led to the use of these processes. We will deliver the goods to customers within 7 days on receipt of. The ceramic deflocculant can reduce the viscosity of the slurry and improve its liquidity.

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. Water in the slurry is reduced and the energy consumption of ball milling and spray drying is also reduced. In addition our product can help make the granular composition of the powdery materials more. In ceramics there are a number of different deflocculants available.

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. In ceramic studios labs and classrooms a good propeller mixer is essential for mixing glaze. The technique is important.
