清洁艺术：Kärcher与艺术家Ralf Schmerberg之间的合作

An unusual kind of cooperation has developed in Berlin-Oberschöneweide: Kärcher is cooperating with the world-famous artist Ralf Schmerberg, who with his team is today creating a place for art, culture and innovation in the former AEG turbine hall, which is now a listed building: the "MaHalla" (). Within the framework of its cultural sponsorship, Kärcher is taking on challenging cleaning tasks in the hall, which has been left unused for decades, and supporting the creation of works of art.

Kärcher专家的一个特殊挑战是清洁“马哈拉”的内部砖头。在表面上从未经过专业清洁过的表面，有数十年的油漆和清漆，其中一些人在189manbext官网手机登陆入口5年建于大厅的时间。与恢复器和国家办事处一起保护纪念碑，有效和同时的温和方法测定，在保留原状的同时可以去除污染。“我们很自豪能够用我们的温和清洁技术促进这个上市网站的恢复，”ThorstenMöwes解释说，作为Kärcher的恢复性清洁专家，负责现场实施。

在第一步中，使用热水高压工艺。在该过程中，80至90度的热水在3至4巴的压力下击中表面。涂料和清漆层的大部分已经被仔细拆除了这种方式。对于顽固的污垢，Kärcher然后使用干冰爆破过程。在该技术中，-79℃冷干冰颗粒被喷射到污染的表面上。在撞击时刻，从固体变化到气态（升华）的干冰，由于升华过程中的体积增加而渗透到污垢并从表面上拆下，而不会损坏壁本身。同时，由于亚单温度和高冲击速度引起的温度差也导致污垢松开。

“马哈拉”正在建造的大厅是AEG核的一部分;欧洲的第一个三相电厂于1895年建于这里。从这里开始欧洲的高压电流扩散，并用它的电气化。与历史性的涡轮大厅一起，“马哈拉”在今天，电气工业的创始中心增长，其峰值沿着狂欢延伸2.5公里。

直到1990年墙的秋季，Wilhelminenhofstrasse的工业综合体繁华了活动：每天五辆国有公司工作最多25,000人。Oberschöneweide被认为是东德能源产业的“心脏”。产生了电力流动的一切。自20世纪90年代初以来，复杂的是在很大程度上是空的。今天，创意商业和科学的前瞻性组合正在列出的工业建筑中发展。

The artist, who comes from near Stuttgart, lived with the Sannyasins in his youth and studied the teachings of Tibetan Buddhism before dedicating himself to self-taught art. In the course of his career, Ralf Schmerberg realized numerous collaborations with international brands, artists and musicians. Schmerberg's diverse artistic oeuvre includes filmic, photographic and sculptural works as well as social gatherings and large-scale media installations in public spaces such as "HOLY WOOD" in Berlin's Tiergarten or "Stromfresser" at Hamburg's Gänsemarkt. His cross-genre and cross-disciplinary projects and stagings are often based on a participatory character, which not infrequently also stimulates social discourse. With the artist collective Music Ashram, Schmerberg has been creating performative sound situations since 2019, in which the audience takes on as creative a role as the artist himself.
