石材防护与石材污染的处理办法

大部分的石头都会染色，因为石头具有孔隙。这使得液体能渗透进石头并蕴藏在石头里面。污渍残留时间越长，渗透越深入，就越长久。因此，及时清除污渍是很重要的。

花岗石是非常耐用、有弹性的石头。日常清洁：用沾有肥皂的尼龙刷按圆周运动刷洗，**后彻底冲洗。日常清洁有助于防止硬水污垢的形成。对付持久性污渍，可尝试使用专业花岗岩去污剂，请查阅天恩石材防护交流[去污除锈剂在石材防护中注意事项]一文，避免使用强碱有害于石材。清除由水、炊具中所含的铁离子造成的铁锈，可使用花岗石**除锈剂。不要在花岗岩上直接使用漂白剂。

大理石具有闪亮优雅的光泽。由于石材所具有的空隙性，要保持这种光泽似乎很难。密封有助于防止石头吸收液体，但酸性液体如桔汁，柠檬，汽水，各种食品，家用清洁剂等会腐蚀石头。基于此，不要在大理石上使用酸性清洁剂。含弱酸液体的湿玻璃杯也会导致硬水渍。为了避免水渍，可使用大理石**的去污除锈剂。清除腐蚀，水渍的**方法是请重新磨光，抛光。日常护理：使用天恩生产的温和的去污剂。

石灰石以其表面镶嵌着贝壳和化石而出名。一些石灰石很“软”，所以你要小心，在使用尖利物品时避免刮伤，划伤表面。石灰石要定期采用穿透性密封剂密封，以防止染色，特别是跟酸性物质有接触时。

皂石表面顺滑。皂石表面非常致密，所以抗污性能强。在用作厨房或浴室水槽的石头中它的孔隙**少。清洁:使用温和的清洁剂，用湿抹布或海绵清洗即可。

去除所有类型石头上的顽固污渍，在咨询专业人士前，可尝试以下步骤。

1）使用中性的石材清洁剂清洗污渍区。如果不起作用，尝试使用去污性更强的清洁剂。要注意哪些类型的石材不能使用哪些化学产品，如上所述。

2）用蒸馏水湿润石头表面。这有助于防止化学物品过快干燥，延长它与污渍接触的时间。

3）准备膏药。膏药是用来吸出石头中的污渍。简单的膏药可在家中制作，一杯面粉，几汤匙液体清洁剂，两者混合搅拌至膏药状。你也可以买化学膏药。如果是红酒污渍，用过氧化氢代替清洁剂。

4）把膏药厚厚地涂在污渍上，盖上塑料膜，用胶布把边缘绑住，放置过夜。

5）24小时之后除去塑料膜。之后继续让膏药干燥。这一步相当重要，因为干燥是把污渍从石头中吸出的动力。然后你可以用刀片或油灰刀刮掉膏药。用水和中性清洁剂清洗残留物。注意，花岗岩比其他石头更多孔隙，所以它能较长时间保湿。如果污渍有消失迹象，但石头呈现暗色，一周之后或更久，重新采用一次。

处理锈斑、污斑（氧化物）主要是除锈去污剂，但由于除锈去污剂多属于酸性，所以对不耐酸的石材如大理石、白云石质，使用前应进行试验，必要时加水稀。

湿敷方法：将药水饱和涂在湿敷材料上（中性粉料或纸、布），稍有外渗，覆盖在患处，待其自然吸收反应还原。湿敷期间应保持湿润，黄锈24小时内转淡或完全除去。如有残余黄锈，应补充药剂继续湿敷，才能彻底除去。

石材污染的出现一般认为防护没有做好，但石材防护有好多种，针对不同的石材有不同的防护剂种类，

 Stone protection and stone approach to pollution
Most stones are stained, because the stone has a porosity. This allows the liquid to penetrate into the stone, and embedded in the stone inside. The longer the stain remains, the more in-depth penetration, the more long-term. Thus, prompt stain removal is very important.
Granite is very durable, flexible rock. Daily Cleaning: Use soap stained nylon scrub brush according to a circular motion and finally thoroughly washed. Daily cleaning will help prevent the formation of hard water fouling. To deal with persistent stains, try using professional granite detergent, please refer to the exchange of Yan stone protection [Decontamination Rust Remover in Stone Protection Notes] a text, to avoid the use of alkali harmful to the stone. Remove from water, cooking utensils contained in the iron caused by rust, you can use granite dedicated rust agent. Do not use bleach directly on granite.
Marble has a shiny elegant sheen. Because stone is the nature of a gap to maintain the luster seems to be difficult. Seal helps to prevent absorption of liquid rock, but the acidic liquid such as orange juice, lemon, soft drinks, various foods, household cleaning agents will be corrosion of the stone. Based on this, do not use acidic cleaners on marble. Weak acid-containing liquid can lead to hard water-soaking wet glass. In order to avoid watermarks, can be used a dedicated decontamination marble rust agent. Remove corrosion, water-soaked the only way is to ask the re-polishing, polishing. Day care: Using Yan production of a mild detergent.
Its surface is studded with limestone shells and fossils known. Some limestone is very "soft", so you have to be careful when using sharp objects to avoid scratching, scratch the surface. Limestone should be sealed regularly with penetrating sealant to prevent staining, especially in contact with acidic substances.
Soap stone surface smooth. Soap stone surface is very dense, so strong dirt performance. The used as a kitchen or bathroom sink stone in its pores at least. Clean: Use a mild detergent, clean with wet rag or sponge can be.
To remove all types of stubborn stains on the stone, in consultation with the professionals before you can try the following steps.
1） Use a neutral detergent cleaning stains stone area. If does not work, try to use the decontamination of a stronger cleaning agent. Should pay attention to what type of stone which can not use chemical products, as described above.
2） Use distilled water wet rock surface. This helps to prevent excessive drying of chemicals to extend its contact with the stain of time.
3） Prepare plaster. Plaster is used to suck out the stones in the stains. A simple plaster can be produced at home, a cup of flour, a few tablespoons of liquid detergent, mixing the two to the plaster-like. You can also buy a chemical plaster. If it is red wine stains, hydrogen peroxide instead of detergent.
4） to plaster thickly coated in stain on the plastic film covered with a cloth tied to the edge, place overnight.
5） 24 hours after the removal of plastic film. Continue to plaster after drying. This step is important, because the drying is to suck out the stain from the stone power. Then you can be scraped off with a blade or putty knife plaster. Clean water and neutral detergent residue. Note that the granite stone more porous than others, so that it can longer period of time moisturizer. If the stains are signs of disappearing, but the dark stone show a week or more after the re-use one.
Dealing with rust spots, smirch （oxide） is mainly detergent rust, but rust mostly acidic detergent, so it is not acid-resistant stone, such as marble, dolomite and quality, should be tested before use, if necessary, add water rare.
Wet packing method: The mixture saturated in the wet packing material coated （neutral powder or paper, cloth）, a slight extravasation, covering the affected area, until their response to restore the natural absorption. Wet compress should be kept moist during the period, yellow rust within 24 hours slowed or completely removed. If remnants of yellow rust, should be added to wet packing pharmaceutical, can be completely removed.
Stone is generally believed that the emergence of pollution prevention is not doing a good job, but there are many kinds of stone protection for different types of stone have different protective agent,
