Kärcher is cleaning the horseshoe-shaped staircase at the Palace of Fontainebleau near Paris
The staircase at the UNESCO World Heritage Site had been exposed to the on-site weather conditions for almost four centuries; the deposits that resulted from this are now being removed using a carefully selected range of cleaning technologies that protect the materials.
将在2021年之前进行清洁
作为他们的文化赞助活动的一部分，Kärcher已经开始在枫丹白露宫清理马蹄形楼梯，位于巴黎南部。强劲的联合国教科文组织世界遗产网站具有非凡的历史意义，在法国人和游客中同样受到的欢迎。它是法国最着名的宫殿之一，每年有超过500万游客。楼梯暴露在现场天气条件下近四个世纪;由此产生的沉积物现在使用仔细选择的保护材料的清洁技术进行拆除。作为第一步，楼梯下方的内部廊道和上面的露台被清洁。楼梯本身在来年完全清洁。
与餐馆老板和所有者的密集合作
“这是什么特殊,清洗过程the right technology has to be found for the type of dirt and also for the different sub-surfaces of limestone, sandstone and brick. Thanks to the intensive and extremely constructive collaboration with on-site with restaurateurs, the Office for the Preservation of Historical Monuments and the owners of the palace, we were able to find the right cleaning methods for the job," says Nick Heyden, who is responsible for the project on-site for Kärcher.
为了除去外部区域的生物生长，首先应用一种有效杀死这一点的药剂。然后使用蒸汽阶段在热水高压清洁器上小心地除去残留物和任何剩余的生长。
在内部廊道中，使用热水高压清洁器和较小的蒸汽净化器上的蒸汽阶段除去烟灰，润滑脂和灰尘，并在微粒喷射过程中除去石灰沉积物。
特殊预防措施
由于工作涉及沉积爆破材料和水，因此封闭了工作区域。使用两种不同的特殊吸尘器收集废水和爆破材料，然后储存在单独的容器中。这意味着任何重金属，例如可能潜在地在砖砌中的重金属，然后正确地处理。Kärcher专家还使用来自KärcherFuturetech的去污淋浴，以确保他们和其他人与爆炸材料没有接触。
