大理石石材特性，在使用过程当中很容易产生病变，非常常见的一种就是石材锈斑。很多人会想到的处理方式就是使用草酸清洗，用草酸直接清洗石材锈斑有什么后果呢？下面氢氧化钾厂家为您解答。

Marble stone features are easy to produce pathological changes in the process of use, and a very common one is stone rust. The treatment that many people will think of is to use oxalic acid for cleaning. What are the consequences of directly cleaning stone rust stains with oxalic acid? The potassium hydroxide manufacturer will answer the question for you.

一、酸并不能洗掉石材的所有污染。因为，酸能分解掉的污染，基本上属于碱性污染，对于色素等酸性污染，用酸洗就不科学了。用碱对碱性污染同样无效。

1、 Acid can not wash away all the pollution of stone. Because the pollution that can be decomposed by acid is basically alkaline pollution. For acid pollution such as pigment, pickling is not scientific. Alkali has no effect on alkaline pollution.

二、破坏石材结构。大理石的主要成分是碳酸盐，即便是性质稳定的硅酸盐花岗石也含有碳酸钙等易分解成分。碳酸盐成分遇酸，会被分解掉（化学攻势，无法抵挡）。主要成分被分解了，石材表面结构自然会被破坏掉。长此以往，石材失光、粉化等病变是迟早的事。

2、 Destroy the stone structure. The main component of marble is carbonate. Even the stable silicate granite also contains calcium carbonate and other easily decomposed components. Carbonate will be decomposed in case of acid (chemical attack, unable to resist). The main components are decomposed, and the surface structure of stone will be destroyed naturally. In the long run, it will be a matter of time before the stone loses its luster and becomes powdery.

三、石材失光。用酸洗石材，尤其是大理石，常见的后果就是失光。这和石材表面钙质成分被分解有关。

3、 The stone loses its luster. The common consequence of pickling stone, especially marble, is the loss of light. This is related to the decomposition of calcium components on the stone surface.

四、石材变黄。这种黄变，一旦发生，可以说是大面积的，尤其是人造石。因为人造石主要是矿粉、树脂等压制而成的，树脂在酸的作用下会加速老化，变黄。而石材结晶抛光的结晶层中，也含有一定的树脂。

4、 The stone turns yellow. This yellowing, once occurred, can be said to be a large area, especially man-made stone. Because artificial stone is mainly made by pressing mineral powder and resin, the resin will accelerate aging and turn yellow under the action of acid. The crystal layer of stone crystal polishing also contains a certain amount of resin.

五、诱发各种病变。酸性溶液渗入石材内部，会诱发各种病变。常见的就是锈黄。铁元素在酸性条件下易被氧化成铁锈。质地较软或碳酸盐含量高的石材，在酸的作用下，会生成麻坑，即被酸刻蚀。

5、 Induce various pathological changes. The acid solution infiltrates into the interior of the stone, which will induce various pathological changes. Rust yellow is common. Iron is easy to be oxidized into rust under acidic conditions. Stone with soft texture or high carbonate content will form pits under the action of acid, that is, it will be etched by acid.

草酸是含酸性溶剂，不仅无法干净锈斑，还会越洗锈斑范围越大，而且对石材的损伤是非常大的。所以要避免使用草酸等含酸碱性溶剂清洗。更多相关产品内容就来我们网站http://www.jinhao360.com咨询看看吧！

Oxalic acid is an acidic solvent, which not only cannot remove the rust stains, but also can expand the scope of the rust stains, and the damage to the stone is very large. Therefore, it is necessary to avoid the use of oxalic acid and other acidic and alkaline solvents for cleaning. More relevant product content will come to our website http://www.jinhao360.com Consult!
