The new household headache facing 89% of households in Kenya is sturbon ceramic stain that has defied conventional stain removal products like the traditional toilet Bowl Cleaner (harpic etc). And we are confronted, on daily basis, by detergent manufacturers seeking to improve the quality of their cleaning Detergents which will meet the expectations and needs of their clients.
In our endeavor to train entrepreneurs seeking to make powerful stain removal products, we have introduced Ceramic Stain Remover classes. To understand how the removal of sturbon toilet seat and bathroom floor works, first let us have a brief look at the essential chemistry of staining process.
The ceramic tile staining process depends on chemical and physical aspects of the tile surface and the staining agents.
The chemical aspects essentially concern the capacity of the staining substance to wet the tile surface,
i.e. its chemical affinity with the glaze or the body.
This wettability can be measured in terms of angle of contact, which is related to surface tension: the lower this value the greater is wetting capacity. Aqueous solutions generallyhave values of between 30° and 50°, whereas oily substances have higher values, normally between
50° and 60°. The chemical affinity is expressed by the polar and dispersed component of surface tension.
The physical aspects concern the structure of the tile surface, in particular the presence of minute
irregularities that allow dirt to adhere to the tile.
In general these consist of pores, small projections and undulations that derive from the forming and
sintering process, as well as scratches, cracks and incisions introduced by the polishing treatments or simply through use (for example, abrasion from walking and cleaning operations).
These various microstructural elements can be measured
in terms of roughness: the rougher a surface the more easily it becomes dirty and the more difficult it is to clean. The values of roughness of ceramic tiles vary considerably, from the 0.1 µm of smooth glazes to more than 2 µm of textured surfaces (expressed as average roughness).
Sounds a little complex but it is not. Our Senior consultant avers that the normal Toilet Bowl Cleaner or Liquid multi purpose detergent cannot remove sturbon stain embedded on the ceramic ware, which is commonly made of the porcelain material. More harsher, but user friendly detergent systems can be made to remove the stain. For professional advice and training, please talk to us on WhatsApp no 0723424240 or visit us in person.
