calcium hydroxide
Description
calcium hydroxide is a kind of grey powder. It consists of calcium oxides, silicon dioxide, ferric oxide and little other ingredients. When mixed with appropriate water and poured into the pre-drilled holes, it will start to expand after half an hour, the expanisve power is increasing as time goes on. It can get 100-123 Mpa expansive power after some hours. Generally, the rock or concrete belongs brittle material, their tensile strength are far less than the compressive strength (for the tensile strength, rock is 1.96-30Mpa while concrete is 1.5-4.0 Mpa, they are equal to 1/10-1/20 of their compressive strength). Therefore, reasonable hole design can easily crack the rock and concrete or reinfored concrete by our BREAK-AG. As usal, it can crack the materials in around 2-24 hours. It is soundless, non-explosive, no noise, no vibration, no flying rock during the process of demolition.
Application
1. Mainly adjust acid waste water pH value, widely used for electroplate, chemical industry, circuit board, pickling, printing & dyeing and paper making, industries waste water treatment.
2. Used to remove phosphate,most of the heavy metal and ammonia nitrogen etc.
3. Used for tanning and mining industry etc.

- Q: Why does not the base noodles rub?
- May add too much water. Noodle black is caused by alkali, you can use the source of gluten instead of edible alkali.
- Q: What is the important character of Chinese made alkali?
- In 1862, the Belgian people Solvay (Ernest Solvay 1838-1922) invented the salt, ammonia, carbon dioxide as raw material for the production of sodium carbonate "Solvay alkali method" (also known as the ammonia method). Since then, Britain, France, Germany, the United States and other countries have established a large-scale production of soda ash plant, and organized the Saul Wei Association, members of the country outside the implementation of technical blockade.
- Q: What to do with the wall
- Wall anti-alkali because there is moisture into the solution is to remove the wall, paint interface agent, brush alkali primer, scraping gypsum, and then putty powder, polished roller or spray latex paint on it.
- Q: What is the name of the alkali?
- Our chemist Hou Diban, invented a [Hou Debang base of the law]. A sensation of the world. This is our pride.
- Q: Our home often burn porridge which put a little alkali inside, so delicious, more entrance, eat often harmful to the health of it?
- Harmful stomach
- Q: Alkali soda water
- Soda water is an aqueous solution of sodium bicarbonate, containing weakly alkaline, medical topical disinfectant, drinking and neutralizing the body's acid-base balance, changing the acidic constitution. Most of the soda water sold on the market is a synthetic carbonated beverage that is compressed into purified water and added sweeteners and fragrances. Soda water is a carbonated beverage, is pressed into purified drinking water into carbon dioxide, and add sweeteners and spices. He is an aqueous solution of sodium bicarbonate, containing weakly alkaline, medical topical sterilization, oral administration can be integrated within the body's acid-base balance, change the acidic body. Sodium bicarbonate is what we say baking soda molecular formula NaHCO3 is usually said that the surface screwdriver, but this is not directly joined the surface screwdriver, the market selling soda water is mostly in the purified drinking water into the carbon dioxide, and add Sweeteners and fragrances of synthetic synthetic carbonated beverages. Baking soda: NA2CO3 soda: NAHCO3, weak base. Medical topical disinfection can be sterilization, oral administration can cure too much acid. Soda water is actually carbonated water Well, Coke, whiskey what is inside. Pure soda water also has, usually the equipment, supermarkets have to sell. Can be used for cocktails. Can go to the pharmacy to buy small soda tablets with warm water to the system, but the concentration is not good to master.
- Q: Do you eat too much alkali to harm your body?
- We say that the base is limited to edible alkali. Edible alkali, is different from the industrial base of soda ash (sodium carbonate) and baking soda (sodium carbonate), baking soda is soda ash solution or crystal absorption of carbon dioxide after the finished product, the two are essentially no difference. Edible alkali is solid state, round, color white, soluble in water. Alcohol is not a commonly used condiment, it is just a food loose agent and meat tenderener, can make dry goods raw materials quickly rise, soften the fiber, remove the dough's sour taste, the appropriate use can bring excellent food The color, smell, taste, shape, to enhance people's appetite. Alkaline used in a large number of food processing such as noodles, bread, bread and so on.
- Q: What is the use of alkali?
- Edible alkali has a small amount of fermentation, but its greatest role is to fermented the surface to the acid
- Q: What is the role of alkali in the surface
- Related to the crowd: the general population can edible production guidance: 1. Alcohol can remove the salad in the oil, the method is to wait until with the aroma of salad oil heated to hot, put a certain amount of soda ash, slowly with chopsticks Even can be; 2. Alcohol can remove the dough's sour taste, and can make the bread bulky white, but can not add too much, otherwise the bread will become yellow or crack, the taste will become bitter. Heat, taste bitter; with dehumidification, the food stagnation, detoxification of the role of acid. Note: 1. Do not put the food in the lye soak, so as to avoid raw materials rot, as long as the appropriate concentration of alkaline water will be repeated washing Several times can be; 2. Alkali is inorganic, itself does not have any nutrients, but the role of food cooking can not be underestimated, alkali solution of the electrolyte is the electrolyte, so that food raw materials (such as squid) in the protein molecules in water Ability to enhance the speed of raw materials to speed up, but should pay attention to master the amount of alkali, methods and time to prevent food raw material was too thoroughly, too bad or even deterioration.
- Q: How to see the whole bread of the alkali alkali small
- Shoot. If you hear the "air" sound, that the alkali put less; if issued a "bash, bang" sound, that the alkali put more.
