沼气厂-防止腐蚀性气体

KEY FACTS:
In agricultural biogas plants animal excrement and plants are processed into nutrient rich manure by fermentation. This process releases high concentrations of biogenic sulphuric acid. The internal concrete or steel wall surfaces are attacked by these gases and can become corroded and porous. In isolated cases the destructive influence is so great that after only a few years there are many centimetres of concrete missing. Waterproofing specific to use and upkeep is indispensible as the plant operator is solely responsible for any water pollution claims. For this reason the main focus of all protective measures centres around the exposure of the interior to chemicals. The SCHOMBURG system products have a targeted anti-corrosive function and protect the surrounding wall areas from aggressive gases.

1
1 裂纹修复

混凝土内的静水或水的裂缝将被专业地密封(参见“裂缝修复”一章)。

2
2 晚上从表面

将asocret - bis -1/ 6在表面上应用于一个厚度为6毫米的操作。将“湿法”涂抹在asocret - ks / HB的浆状粘结层上。

3
3 产生凹圆形角

刷应用ASOCRET-KS / HB。然后,当这件外套仍然是湿的,用最小的长度为4厘米,用钢泥刀或在墙/地板交界处用泥刀的方式,将一段长度为4厘米的圆角的圆角。

4
4 过渡法兰建设

在施工中有法兰的地方,在法兰施工中应用特殊底漆asodur - sg2 - thix,使用短毛皮辊防止气泡形成,并立即用粗石英砂进行广播。一旦充分硬化,就可以采取进一步的防水措施。

5
5 占先执行

墙面:首先均匀地将一种短毛皮辊涂在asodur - sg2 - thix上,然后用启动刷彻底地将其涂在表面,然后再与毛辊进行反向滚动。
地板:用双叶橡胶刮刀将asodur - sg2应用于部分,彻底刷入和后滚。
在两种情况下,用粗石英砂对湿底漆进行盲涂。

6 保护涂层1应用程序

用滚子、喷雾或刷子将其涂上。等待大约。连续的外套之间16 - 24小时。

7
7 保护涂层2应用程序

使用相同的方法再涂一层asodur - v2370。
