Ceramic grit binders are often regarded as simple fixing agents, but their role within the production process is far more complex. In this episode, we explore how the management of rheology…
[instrumental music] As I've just said in the introduction, in the ceramics industry, grit binders are often seen as purely functional products.
They sit at the heart of a delicate balance involving rheology, application methods, material composition, and production line setup.
And it is precisely this complexity that gave rise to the Granicer range over time, not as a single linear project, but as a gradual layering of solutions, each developed in response to specific production needs.
Today, the range is organized into four main families: Series 6, Series 7, Series 9, and Series S, which are not simply product variants, but genuine technological responses to different moments in the evolution of ceramic manufacturing.
In terms of chemical composition, the series also differ in their components.
Some are based exclusively on organic polymers, while others incorporate selected inorganic com- components that actively contribute to the rheological behavior of the system.
It directly influences how each product interacts with the grits, the production line, and the process condition.
So it is quite, uh, clear and, uh, a useful way to understand the logic that sets the families apart behind their individual application performance.
To understand the logic behind the range, it is essential to start from a key concept that emerges clearly from application experience, at least our experience, of course.
As I said, binding strength is not the main criterion for production selection.
In most cases, once the grit have been applied, they are not subjected to the kind of stresses that would require strong adhesion before firing.
And you perfectly know, like at least those of you are working on the production lines.
The binder's ability to control viscosity, keep solid particles in suspension, ensure proper wetting of the granules, and allow for an even application.
And factors such as air circulation, distances between machines, application methods, and equipment configuration can lead to completely different results with the same product.
It is not uncommon, for example, k- that for the same binder to work perfectly on one line and cause problems on another.
