Last week Munich hosted one of the largest ceramic exhibitions: Ceramitec 2018. From 10-13 April the international ceramics industry gathered around the exhibition, which was, in general terms, really successful. In case you couldn't attend, we were there to be able to show you.
When it comes to the use of ceramic additives, we must be 100% sure that the one that we are using is the best for their production process. We have talked about different ways to optimize ceramic production processes in several blog articles and we even wrote a blog post on the benefits of using additives in a brick production. However, we have received many questions about how additives can affect a manufacturing process. We will try to answer all of the questions as well as we can. This month's question is: "will the additive block my extruder if there's a production break?"
In August 2017, humans had already used up more natural resources than the Earth could renew for the whole year. This means that last year, humanity lived on “credit” from the Earth from August to December. There are studies predicting a consumption of 2 whole planets every year by the year 2050. Our ecological footprint as a society is increasing and we are reaching Earth Overshoot day each year earlier. You can calculate your ecological footprint and surprise yourself with how many planets you would need to keep up with your lifestyle. Our planet is crying out for help and we need to understand the urge for a more sustainable style of living.
Tile sizes have been increasing lately not only because large tiles have become a trend, also because of the improvement in the technology that allows to make these tiles. In some of our blog posts we already talked about trends in the market and about avoiding breakage in large tiles but, how big can a tile reach to be?
Why does an efflorescence appear?
In chemistry, efflorescence is defined as the migration of a salt to the surface of a porous material, where it forms a coating. The essential process usually involves the dissolving of an internally held salt in water. The water, with the salt now held in solution, migrates to the surface, then evaporates, leaving a coating of the salt. These efflorescent salt deposits tend to appear at the worst times, usually about a month after the building is constructed, and sometimes as long as a year after completion.
The video underneath shows an Indonesian factory producing large porcelain tiles. These white body tiles measure 120cmx60cm and, as you can see, due to its large size and thinness, they break easily during the production process, especially in those plants where layout imposes direction and/or level changes. Breakages and cracks are usual and happen for several reasons. The good news is that there are also various ways to deal with them. In the video, adding additives was the most effective way to mitigate this breakage rate.
