ceramic materials A FULL BODY AND HIGH DURABILITY, THROUGH THE USE OF BIOCOMPATIBLE AND TIMELY INFORMATION MICROTECHNOLOGIES
We start from the currency tion of the fundamental requirements underlying the ecological compatibility of the elements of construction, the principles of green building that is applicable to construction materials and in particular those for floor and wall. The actual and not just advertised to meet the requirements of green building is the platform for the confirmation of the ecological compatibility of the material, even if "any misleading advertising also contains in itself a good thing because expresses the 'negligence of an existing label, helping to evolve into what the specific sensitivity of the consumer real value of this requirement. "cladding materials that can better or more fully meet the requirements above are the sites you typically terrecot "full body" and the actual average rate of absorption, not ideal or only one certificate for some episodic analysis, approximately above all '1%.
WHAT THE POTTERY
When we speak of "terracotta t" indicates a macrocategory of artificial materials composed of inorganic minerals taken from lands windows crust, mix together with the binder and water, compacted by pressure and made finite by the AC lore.Tutti materiali così otte nuti sono intuitivamente sem plici, di estesa reperibilità e di facile attuabilità. Ad essi non ven gono aggiunte superficialmente altre sostanze (smalti, colo ranti, vetrificanti, ecc), né in prima né in successive cottu re e pertanto si mantengono praticamente uguali, cioè con le stesse caratteristiche chi mico fisiche, in tutto lo spessore del manufatto ottenuto: da ciò deriva il termine "a tutto spessore o massa".
Cosicché, pur annoverando tra loro materiali diversi come estetica, prestazioni e carat teristiche gestionali, essi ri spondono per definizione o composizione originaria ai pri mi sette requisiti della bio compatibilità. Nella Tav. 2 raggruppiamo di tali materiali Full body most significant ones. Beyond the differences in performance do indemnities received diagrams factory processes apart, is rather straightforward to find these materials to meet the following pa rameters. But it is the naturalness and responsiveness to these parameters is the origin of their weakness. For some accepted almost ras assignement (see terrecot you and bricks), others because of the sharp decline in the market (Cotto Tile red clinker and the like), while the porcelain or dangerously ill-concealed ill-digested.
THE PORCELAIN
Until a few years ago, the porcelain was presented as the Committee ce ramic material to the whole mass cally indestructible and private lawns of vo degenerabilità. He then thought of the market, u nico final and secure the control and experimental laboratory experimentation for all materials but, rather to highlight the presence and the variance of fe nomen degradative harder to defend. Today so that all or most of the producers of porcelain appropriate to present a more or less qualified table recom mendations for its conservation.
Aware, however, that it is not always possible or easy to regenerate or clean the material in question, we hurried to go beyond superficial in troducendo the glazing on the porcelain raw, and this, in addition to the re dirtying Durno, gives even greater beauty and ver satilite aesthetics to the finished tile. A similar choice had already been made for years by the pro ducers of clinker: appropriate to give the same flaming and toned, no doubt stand on the holy truth of aesthetics, has begun to glazed surface, especially in anthropology more absorbent and call you king.
This trend was af stop Cotto and even the cola pic also on clay, but heard the faint call for proactive protection and termination of these was met by several manufacturers introducing glazing, and financial maiolicature that unstable surface finishes required ot application of polymer emulsions, with the objective of better present the material but especially to deceive the consumer an easy storability.
and biocompatibility '
All these, however, have done irreparable disappearance foregoing principles of the bio compatibility of these materials to the entire mass.
Hence the invitation to all producers on if we want to preserve the unique and original ecocompatibiltà of these materials, they must be added to the innovation that complements and supplements but does not destroy or reduce these parameters.
is, it must be added to them that something is not irreversible, which will improve the weak side of the original features of the dura bility and conservation so as to make them complete enough with the whole picture of the true requirements for biocompatibility.
Pertanto, se è vero che dal Gres porcellanato al Cotto e al laterizio tutti i materiali assorbenti si macchiano e degenerano più o meno velocemente, è altrettanto vero che, per dar loro la patente di materiali adatti alla bioedilizia e nel contempo al mercato, vanno ad essi conferite caratteristiche che originariamente non hanno o di cui sono carenti, attraverso:
riduzione dell'assorbimento idrico specifico senza annullare la necessaria traspirazione;
riduzione dell'ancoraggio e penetrazione delle macchie, così da poterle asportare con facilità;
diminuizione della tendenza al degrado e alla decoesione, soprattutto per i materiali a bassa durezza e aggregazione superficiali;
prefinitura but to give the materials to the whole mass suddet will benefit both on site and in plant / facility (operational and process inno vation).
These objectives can only be achieved through the use of protective Micropreparation exclusive gift and technologies targeted interventions (enamel, paint, resin, etc..) Which not only distort the originality of the material but above all I know is irreversible and that is not easily echo economically sources.
I say this without taking anything away from these measures irreversible, they have all our respect but should be defined to call security technology and as such authority as understood and accepted by the EU today also establishes the specific European legislation (Directive 2005/29 EC).
On the other hand, the intervention of protection only recited or surface can not fix it! Unfortunately, but also fortunate na, it is proven with studies and preparations for a long time, and with research and innovation, is articulated with technologies that will nourish the absorbing demands of eco-buildings.
It is with the technical effort interdisciplinary Pliny (petrographic chemical co design etc.) and appropriate technology, there is yet little known to the competent or transmitters that both haunt us and attack us, we can win the battle of ecology and of globalization.
