Its high melting point makes it useful as a refractory lining in metal and glass furnaces.</p> <p>An all natural Magnesium Oxide cold ceramic cement based building sheet replaces drywall, OSB and plywood sheeting at competitive pricing to paperless drywall and plywood products. Used extensively in Asia for years, and recently used as both interior and exterior sheeting on the largest building in the world. These products out perform conventional materials in many ways.</p> <p>The Magnesium Oxide ceramic cement based board is fire, mould, water and shrink resistant and breathable. It is an all natural mineral sheeting material that offers a health building option, there are now over 500,000 sheets of MgO panels installed on homes and commercial buildings in the USA.</p> <p>There is a way to make our city streets as green as the Amazon rainforest. Almost every aspect of the built environment, from bridges to factories to tower blocks and from roads to sea walls, could be turned into structures that soak up carbon dioxide, the main greenhouse gas behind global warming. All we need to do is change the way we make cement. The alternative cement based on magnesium carbonate rather than calcium carbonate, could reduce climate change without sacrificing modern living.</p> <p>The Kyoto Protocol was a good effort but it got things wrong when it assumed that trees were the only things that could absorb carbon from the air. This magnesium based material could be cheaper to manufacture than cement, more durable and soaks up CO2, if the building industry listens, cities and their suburbs could turn into sinks for CO2 as effective as the natural grass and woodland they replaced. For every tonne of cement emerging from the kilns, roughly a tonne of CO2 gas escapes into the atmosphere. Cement manufacture is responsible for around 7% of total man made CO2 emissions worldwide, a figure that rises above 10% in fast developing countries such as China, which currently manufactures one in every three tonnes of cement made around the world. If we mean to control global warming this situation can t go on. This solution being brought onto the market is to replace the calcium carbonate in the kilns with magnesium carbonate a rock that occurs widely on its own, as the mineral magnesite, or in mixtures with calcium carbonate, such as dolomite. Magnesium based cements are not new, they were first developed in 1867 by the French.</p> <p>This material has a number of major environmental advantages. For a start, the kilns don t need to be run so hot. Magnesium carbonate converts readily to magnesium oxide at around 650oC. This means that emissions of CO2 from the energy used to fire kilns are roughly halved. If eco-cement is used to make porous materials like masonry blocks virtually all the material will eventually carbonate. A tonne of concrete can end up absorbing up to 0.4 tonnes of CO2 equalling about 100 kilograms of carbon. The opportunities to use carbonation processes to sequester carbon from the air are just huge. It can take conventional cements centuries or even millennia to absorb as much as eco-cements can absorb is just a few months. This means that eco-cements quietly carbonating in a tower block could be performing much the same atmospheric function as a growing tree and if eco-cements gained a foothold in our cities, they could immediately reduce the cement industry s contribution to global warming, reabsorbing much of what was emitted in their creation, it is estimated that we could eliminate over a billion tonnes of CO2 each year.</p> <p>The market for cement is so vast that it is difficult to see magnesium cements making much of an impact in the next 10 years but perhaps as the world tries to think up new ways of cutting back on its emissions of CO2, eco-cement may have its day. Our burning of fossil fuels is force feeding Earth s atmosphere with CO2 at a rate that vegetation can no longer absorb. The logical way out is to accelerate the formation of carbonate with our own man made rocks. What better way than in cement and building homes with magnesium oxide sheeting.</p> <p class="next"><a href="News.html">< Frist ></a> <a href="News2.html">< Previous ></a> <a href="News2.html">< Next ></a> <a href="Mag.html">< Last ></a></p> </div> <div id="clear"></div> <div id="new"><p><label><a href="News.html">More&gt;&gt;</a></label>News Center</p> <ul> <li><a href="News.html">1.How to nominate in the 2010......</a></li> <li><a href="Mag.html">2.Magnesium Oxide  An Understanding.....</a></li> </ul> </div> <div id="new"><p><label><a href="Contact.html">More&gt;&gt;</a></label>Contact Us</p> <div class="left"></div> <ul class="contact"> <li>Tel:+852 6470 9887</li> <li>Fax:+852 2414 3796</li> <li><a href="mailto:info@ugmaterials.com">info@ugmaterials.com</a></li> </ul> </div> </div> <div id="clear"></div> <div id="footer"> <div class="ico"></div> <ul> <li>Copyright &copy; 2009-2012 United Global Materials Ltd All Rights Reserved.</li> <li>Address: Unit 3, 10/F, Block B, Hi-Tech Industrial Centre, 491-501 Castle Peak Rd, Tsuen Wan, Hong Kong</li> <li>Phone:+852 2416 9113 &nbsp;&nbsp;&nbsp;&nbsp; Fax:+852 2414 3796 &nbsp;&nbsp;&nbsp;&nbsp; Email: info@ugmaterials.com</li> </ul> </div> </div> </body> </html>
