Tenacer: Z&S temporary binders

Before addressing the ranges, I would like to provide you with a short introduction about the scenario in which we are working, even if you already know.

We have done it before, but a recap is always welcome.

So, in today's ceramic manufacturing environment, that is marked by large formats, thin slabs, super wide bodies with a high glassy fraction and increasing variability in raw materials, controlling mechanical strength has become one of the most sensitive variables across the entire production process, we could say.

Achieving the right balance between sprite-ride granular cohesion, sleep workability, biological stability, and press behavior has grown progressively more complex, especially in a context where clay quality and availability can no longer be taken for granted.

And we know the reason.

So, it is within this framework that the Tenature range developed by Schumann und Schwarz plays its role, and all the products that make up the range were designed to increase granular strength and enhance the modulus of rupture of time in the green state.

More broadly, when we talk about additives for ceramic production, essentially it means examining substances capable of regulating how water behaves throughout the various stages of the process.

What does that mean? It means that water is a fundamental career in many steps of ceramic manufacturing, from milling to shaping and, of course, along the blazing line where aqueous suspensions follow one another continuously.

so when focusing specifically on binder the residual moisture that is by the way water the moisture content in a spray dried powders is the parameter that gives the granule the plastic deformability required during pressing so we could say the residual moisture content is essential but At the same time, it can also become a potential source of instability because uncontrolled moisture levels, either too high or too low, makes powder difficult to compact and can generate defects that also affect the subsequent process stages.

So binders operate in close synergy with the water retained in the powders.

Their action improves pressing performance by reinforcing the cohesion of solid particles and increasing the mechanical strength of the green body.

That said, let's start talking about how these additives can be added to the suspension.

Today, additives from the tannature range are almost exclusively dosed in line immediately before spray drying, because the practice of adding them directly into the main slip tank has gradually been phased out because it is difficult to control on large volumes and incompatible with the level of formulation precision now required.

A line injection instead enables far more accurate dosing and better dispersion, also minimizing the risk of concentration gradients and allowing faster adjustment to the production needs.

Naturally, the binder's impact on sleep rheology must be carefully monitored.

Any viscosity variation must remain within limits compatible with spray drying and particular attention must be paid to preventing localized cell formation or inhomogeneity at the injection point, which could otherwise compromise the entire system.
