Reverse Alkali Crystallization of Marble
If it was a slight marble anti-soda crystal, the treatment method was as follows: 1. Cleaning: Use the "crystal flour machine + cleaning pad" to clean the alkali-returning floor as a whole with clean water. You can also use the washing machine to improve the efficiency. 2. Water pumping: After cleaning, use a high-power pump to drain the water. If the alkali-reverse reaction was so severe that the gaps in the stone could be seen carefully: 1. Cleaning: Use the stone material scavenger to clean the anti-soda area with water. 2. Water pumping: Use a pump to drain the water. 3. [Protection: Use a protective agent to protect it.] In terms of preventing the crystallization of marble: 1. Before the stone is installed, it will be fully and effectively protected to prevent the stone from returning to the base. According to the type and material characteristics of the stone material, the effective selection and protection of the stone material should be done. For example, the protective agent selected for limestone and metamorphosed rock should have an alkali-resistant function. 2. The bottom and surface of wet stone materials should be protected separately. Protective agents should be used to prevent alkali-resistant and salt-resistant stone materials without affecting the cohesion. The protection of stone materials should not be omitted because of the "waterproof gum". When used on limestone surfaces, it should be waterproof and alkali-resistant. For carbonate-type stone materials, especially soft marble, it is forbidden to use a strong alkali-resistant protective agent such as methymethy-silica.(Ordinary water-based protective agent), and use a weakly basic environmental protection type of high-end water-based protective agent. Be sure to wipe off the residual alkali-based mist on the stone surface in time. 3. Before protection, make sure that the stone is completely clean and dry, and do not leave any moisture in the stone. If this condition is not met, it is better not to protect it, and not to force it.

How to deal with the reverse alkali-resistant wall
The reverse alkali-resistant wall can be treated according to the following methods: 1. ** Anti-Alkali Wall Removal **: Remove the wall at the anti-alkali position. The removal range should be larger than the original anti-alkali position, all the way to the cement base. 2. ** Oxalic acid treatment **: Add water to the wall after removing it (the rate of adding water depends on the severity of the anti-alkalization). After the sulfuric acid is dry, add the sulfuric acid treatment again. 3. ** Mortar Surface Treatment **: After the sulfuric acid treatment, use the mortar for surface treatment. 4. ** Water-proof wall lining treatment **: After the two layers of mortar are treated, use the waterproof wall lining to level the surface. 5. ** Painting Alkali-resistant Primer **: Use Alkali-resistant Primer to paint the wall. 6. ** Surface coating treatment **: Finally, the surface coating treatment is carried out. You can also shovel away the white ash on the anti-soda parts and brush it with anti-soda products. Or, you can make the board completely waterproof as soon as possible to prevent moisture from continuing to invade so that the anti-soda will not expand. You can also use the anti-soda cleaners on the market to clean it.(This cleaning agent is a colorless translucent liquid made of a non-ion type surface active agent and a solution. It has a certain effect on the anti-alkalitic cleaning of some walls.) If there are cracks on the exterior wall, you can use cement and 801 glue to repair the cracks. Brush the cracks three times (once a day). It is best to scrape the entire wall twice with cement and 801 glue, or do a layer of cement paste outside the wall. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What's the best way to reverse the alkali-like substance on the skirting line?
After the floor tiles are laid, how to deal with the reverse alkali-filled wall corner?
After the floor tiles were laid, the corner of the wall would turn back into an alkali-like substance. There were several ways to deal with this. First of all, he could use a dry cloth to wipe the anti-alkalitic area as clean as possible and wipe off some of the white alkali-like substance. After that, he would get some sulfuric acid or white vinegar and dilute it with water. The ratio was about 1:10. Then, he would take a brush and dip it in the diluted solution to brush the anti-soda area. After brushing it a few times, he would rinse it with water. If the anti-alkalization was more serious, he might have to re-handle the cracks in the floor tiles at the corner of the wall, dig out the original caulking agent, clean up the gaps, and then re-caulk. When caulking, use the kind of good quality and waterproof caulking agent. This could reduce the occurrence of anti-alkalization. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Alkali react with oil
The reaction between the base and the oil was called a soap reaction. During the reaction process, the fatty acid ester and other components in the oil react with an alkalium (such as NaOx). The reaction equation is (C17H35COO) 3C3H5 + 3NaOx → 3C17H35COONa + C3H5 (Ox)3, which will form water-dissolved soap and glycerine. After the oil was detoxified, it formed a salt of high-grade fatty acid. This salt was both water and oil dissolved, which was beneficial to the removal of oil stains. Moreover, when the oil was heated under an acidic condition, it would form fatty acid and glycerine, which not only increased its water dissolution but also produced a surface active effect, making it easy to remove the oil. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Strongest Alkali Metal
Alkali metals included lithium (Li), Na (Na), K (K), rubidium (Ru), caesium (Cs), and Fransium (Fr). The activity of the six metals increased in the order of Li, Na, K, Ru, and Cs. Their highest-valued oxide-like compounds, LiOx, NaOx, KOx, RbOx, and CsOx, were all strong bases, and their basicity gradually increased. Because the half-life of its longest-lived atom was only 22 minutes, it was basically unstable in nature. It was difficult to compare the strength of the base it formed. Therefore, among the stable alkali-metals, the base formed by caesium (Cs) was relatively the strongest. Click on the link below to read "The Strongest in History" comic

Alkali and Acid Reaction
Alkalines and acids can react. In general, the acid was weakly acidic, and it could react with strong bases. For example, when a commonly seen alcoholic substance such as starch reacted with soda, it would form water and water. The chemical equation of the reaction was probably C H Oh + NaOx → C H ONa + H O. This was a typical reaction type in organic chemistry. It was important in chemistry studies and chemical industry production. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What are the methods of crystallization?
There were two main methods of liquification: one was to lower the temperature (applicable to all gases at any temperature); the other was to compress the volume (applicable to certain gases at a certain temperature, generally at room temperature, special ones must first reduce the temperature and then compress the volume). In practical applications, both methods could be used. Any gas could be liquefied when the temperature dropped sufficiently. However, when compressing the volume, if the temperature of the gas was higher than its critical temperature, it could not be compressed to be liquefied.
