3,300岁的方尖碑恢复和清洁

The 3,300-year-old Luxor obelisk on the Place de la Concorde in the heart of Paris is being restored and gently cleaned to mark the 200th anniversary of the decipherment of Egyptian hieroglyphics. The project is a cooperation between Kärcher and the French Ministry of Culture. Kärcher is not only financing the complete restoration of the valuable monument as part of its cultural sponsorship, but is also carrying out the cleaning itself.

Most of the cleaning is done with the so-called low-pressure micro-particle blasting method. With a surface pressure of only 0.5 to 1 bar and a distance of 15 to 20 cm, most of the deposits caused by weathering and emisson contamination can be removed. To protect themselves against the fine dusts produced in the process, the cleaning specialists wear full-body protection with a breathing mask and fresh air supply.

恢复卢克索方尖碑

1822年，法国语言学家Jean-FrançoisChampollion的象形文字解读了200周年。借助于罗萨斯石，其中包含不同语言的铭文，Champollion成功地解读了丢失的书面语言。尖锐的II铭刻有许多象形文字。为了纪念这一历史日，今年在法国有许多展览和活动，其中在卢浮宫和Champollion的出生地的其他展览会上。

这些污染主要由大城市的排放量组成：从车辆的排气烟雾，空气污染物，如细尘和烟囱烟灰。据推测，由于它已在法国，这些只是在方尖碑的表面上。大多数清洁采用温和的低压颗粒喷砂法进行。

首先，进行综合措施，即保护现有结构的措施。这包括去除旧的，现在损坏的环氧树脂灌浆，新的灌浆和损坏区域的整合。用海绵的恢复液擦拭镀金的金字塔和对方尖碑的镀金雕刻，并磨合被大修并恢复。

The obelisk on the Place de la Concorde was made in the 13th century BC in the 19th dynasty under the pharaoh Ramses II and stood in the temple of Luxor in Upper Egypt until the beginning of the 19th century. The Viceroy of Egypt, Muhamed Ali Pasha, made it a gift to the French King Louis Philippe in 1829. The extremely complicated transport by ship to France took three years and after the obelisk arrived in Paris in the summer of 1834, it took another two years until it could be erected - in front of more than 200,000 spectators and with the help of an elaborate wooden construction. It is the oldest monument in Paris.
