草酸直接清洗石材銹斑有什么后果

發(fā)布來(lái)源:http://m.ileleli.cn    更新時(shí)間:2022-08-17 點(diǎn)擊數(shù):201

石材常見(jiàn)的銹斑成因,一般可以分為兩種:一種銹斑的成因是來(lái)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(shí)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(chǎng)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?yàn)椋崮芊纸獾舻奈廴荆旧蠈儆趬A性污染,對(duì)于色素等酸性污染,用酸洗就不科學(xué)了。用堿對(duì)堿性污染同樣無(wú)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(jié)構(gòu)。大理石的主要成分是碳酸鹽,即便是性質(zhì)穩(wěn)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(huì)被分解掉(化學(xué)攻勢(shì),無(wú)法抵擋)。主要成分被分解了,石材表面結(jié)構(gòu)自然會(huì)被破壞掉。長(zhǎng)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(jiàn)的后果就是失光。這和石材表面鈣質(zhì)成分被分解有關(guān)。
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(fā)生,可以說(shuō)是大面積的,尤其是人造石。因?yàn)槿嗽焓饕堑V粉、樹(shù)脂等壓制而成的,樹(shù)脂在酸的作用下會(huì)加速老化,變黃。而石材結(jié)晶拋光的結(jié)晶層中,也含有一定的樹(shù)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(fā)各種病變。酸性溶液滲入石材內(nèi)部,會(huì)誘發(fā)各種病變。常見(jiàn)的就是銹黃。鐵元素在酸性條件下易被氧化成鐵銹。質(zhì)地較軟或碳酸鹽含量高的石材,在酸的作用下,會(huì)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(lái)除銹,不過(guò)使用時(shí)要小心,草酸對(duì)不銹鋼有較強(qiáng)的腐蝕性。濃度高的草酸也容易腐蝕手,皮膚接觸草酸后,應(yīng)及時(shí)用水清洗。更多注意事項(xiàng)就來(lái)我們網(wǎng)站http://m.ileleli.cn咨詢(xún)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.
