Effective facades cleaning – from plaster to metal
If the exterior of a building is maintained this helps retain or increase its value. Various methods are available to clear dirt from facades. But the surface should be taken into consideration when applying the respective technology. This is essential for avoiding damage. An overview about techniques and regulations.
该standard: Cleaning with hot water and steam
Facades are the flagships of buildings. Often they are large, complicated surfaces made of different materials. Exposed to external environmental influences for years, dirt can settle and accelerate weathering in different ways.
Hot water high-pressure cleanershave proven an effective, economical method in facade cleaning due to their high cleaning performance by low water consumption. Withtrailer based variantseven self-sufficient working, independently of electricity and water network, is possible.
该advantages of hot water high-pressure cleanerscompared to冷水高压清洁剂基于两个方面:
初步测试是明智的:
选择合适的技术,避免损坏。
无论是否存在哪种外立面材料 - 为了选择正确的技术,在每种情况下,应预先明显地进行样本区域。是对酸敏感的立面,它吸收水吗?哪种清洁剂达到了浓度和时间的所需效果?仔细前进的人达到预期的结果,并避免由于清洁剂不正确的物质或物质去除或其他永久性损坏。

清洁剂增强效果
一种cleaning agent如果需要,可以进一步增强高压清洁剂的效果。在应用程序中建议使用所谓的两步方法。这里首先施加清洁剂,然后在施用时间后在高压下洗掉。但是,在选择清洁剂时,应观察到表面的质量和法定规定。
Know what's right:
Requirements and regulations.
立面清洁总是在公共场所进行,这意味着获取不同地方和国家的要求和法规信息非常重要。废水排放须经批准。如果只是脏水,可以过滤后排放。收集的固体材料必须处理掉。如果使用清洁剂,则必须收集、过滤和中和水。另外,对于使用喷雾剂、产生灰尘、噪音或废气,必须遵守相应的规定。
对于特殊情况:粒子和干冰
Particle and干冰爆破是受欢迎的替代高压清洗。尤其是如果外墙不需要浇水过多或节水的方法是必要的。如果不使用清洁剂或废水量有限制,它们也是高压清洁剂的良好替代品。这两个程序,粒子和干冰爆破,也适用于消除严重污染,例如涂鸦。
颗粒爆破
With low-pressure particle blasting a jet gun is supplied with compressed air via an industrial compressor. In addition, a very fine, soft spray agent and water are added to the air in the mixing chamber for dust-binding work. An important factor in the selection of the spray agent is that its Moh hardness and the grain size must be individually selected for the contamination and the original façade surface. The mixture of air, water and spray agent emerges at the nozzle of the trigger gun, whereby air pressure, water volume and spray agent volume are individually adjustable. Surfaces with minimal abrasion can be cleaned in this manner.
干冰爆炸
用于干冰爆破ablaster,它将冰块注射到空气喷射单元中,以及aspray hose具有trigger gun空气-冰混合物通过喷嘴到达表面。还需要有足够气压和气流速度的压缩机。机械能对清洗性能起决定性作用。
具有低莫氏硬度(1-2)的干冰颗粒可以以150 m/s的高速喷射到表面上。当冻结的CO2在-79°C的温度下撞击时,这是由热能支持的,尤其是对于注射模等温暖表面。因此,污垢变得易碎,因此很容易清除。乐动体育-app安卓
使用几乎不具研磨性的方法,可以去除各种表面上的油、油脂、粘合剂或粘合剂,清洁敏感表面,也可以去除金属上的油漆,而不会造成任何损坏。
