            草酸直接清洗石材銹斑有什么后果

            石材常見的銹斑成因,一般可以分為兩種:一種銹斑的成因是來自石材本身所含的鐵元素;其二是銹斑是外部原因,例如殘留的的鋼砂或施工時的鐵器,裝潢的金屬器件等等。那草酸直接清洗石材銹斑有什么后果?氫氧化鉀廠家為您講解。
            The common causes of rust spots on stone can be generally divided into two types: one is caused by the iron element contained in the stone itself; The second is that the rust is caused by external factors, such as residual steel sand or ironware during construction, decorative metal parts, etc. What are the consequences of directly cleaning stone rust with oxalic acid? The potassium hydroxide manufacturer will explain it to you.
            一、酸并不能洗掉石材的所有污染。因為,酸能分解掉的污染,基本上屬于堿性污染,對于色素等酸性污染,用酸洗就不科學了。用堿對堿性污染同樣無效。
            1、 Acid can not wash away all the pollution of stone. Because the pollution that can be decomposed by acid basically belongs to alkaline pollution. For acid pollution such as pigment, pickling is unscientific. Alkali is also ineffective against alkaline pollution.
            二、破壞石材結構。大理石的主要成分是碳酸鹽,即便是性質穩定的硅酸鹽花崗石也含有碳酸鈣等易分解成分。碳酸鹽成分遇酸,會被分解掉(化學攻勢,無法抵擋)。主要成分被分解了,石材表面結構自然會被破壞掉。長此以往,石材失光、粉化等病變是遲早的事。
            2、 Damage the stone structure. The main component of marble is carbonate. Even silicate granite with stable properties also contains calcium carbonate and other decomposable components. The carbonate component will be decomposed when it meets with acid (chemical attack cannot be resisted). If the main components are decomposed, the surface structure of the stone will be destroyed naturally. In the long run, it will be a matter of time before the stone loses light and becomes powdered.

            三、石材失光。用酸洗石材,尤其是大理石,常見的后果就是失光。這和石材表面鈣質成分被分解有關。
            3、 The stone loses its luster. The common consequence of pickling stone, especially marble, is loss of light. This is related to the decomposition of calcium components on the stone surface.
            四、石材變黃。這種黃變,一旦發生,可以說是大面積的,尤其是人造石。因為人造石主要是礦粉、樹脂等壓制而成的,樹脂在酸的作用下會加速老化,變黃。而石材結晶拋光的結晶層中,也含有一定的樹脂。
            4、 The stone turns yellow. Once this yellowing occurs, it can be said to be a large area, especially artificial stone. Because artificial stone is mainly pressed by 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、誘發各種病變。酸性溶液滲入石材內部,會誘發各種病變。常見的就是銹黃。鐵元素在酸性條件下易被氧化成鐵銹。質地較軟或碳酸鹽含量高的石材,在酸的作用下,會生成麻坑,即被酸刻蝕。
            5、 Induce various diseases. The acid solution infiltrates into the stone, which will induce various diseases. Common is rust yellow. Iron is easily oxidized to rust under acidic conditions. Stones with soft texture or high carbonate content will generate pits under the action of acid, that is, they will be etched by acid.
            總之草酸可用來除銹,不過使用時要小心,草酸對不銹鋼有較強的腐蝕性。濃度高的草酸也容易腐蝕手,皮膚接觸草酸后,應及時用水清洗。更多注意事項就來我們網站http://www.festivalmatsuri.com咨詢了解吧。
            In short, oxalic acid can be used to remove rust, but be careful when using it. Oxalic acid has strong corrosiveness to stainless steel. Oxalic acid with high concentration is also easy to corrode hands. After skin contact with oxalic acid, it should be washed with water in time.
