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: I have been very confused, baking soda and edible alkali surface is the same thing? Tea in the consumption of baking soda is not become alkaline? Can drink? How to quickly become alkaline? In addition to more melon Fruit and vegetables outside
- General baking soda can be in the food additives store can buy baking soda. Chemical reagent points can also buy baking soda.
- Q: What is white alkali?
- Sodium carbonate [497-19-8] (Na2CO3), molecular weight 105.99. Chemical purity of more than 99.5% (mass fraction), also known as soda ash, but the classification belongs to the salt, does not belong to the base. International trade, also known as soda or alkaline ash. It is an important organic chemical raw materials, mainly for the production of flat glass, glass products and ceramic glaze. But also widely used in life washing, acid and food processing.
- Q: What is called alkali recovery
- For alkali recovery, the assessment of the extraction section is the concentration and temperature. Concentration: 8 ° Be; Temperature: 70-80 ° C.
- Q: What is the difference between baking base and common base?
- What the main content of ah, is not a thing. Baking alkali refers to caustic soda, caustic, caustic soda, and molecular sodium hydroxide, while the commonly used edible base refers to sodium carbonate.
- Q: Last called me to buy salt, but can buy a bag of alkaline powder to go home. Want to know what can use alkali powder?
- In addition to medicinal function, alkaline powder also has a strong decontamination function. I brought a cup full of dirt, rinse with water, and then rubbed and rubbed by hand, but the dirt or tightly stick the cup. I add detergent, but also hard to rub, or stubborn dirt still still motionless. I sprinkled with alkaline powder, rubbing the side of the water gently rubbing the cup, those dirt seems to be afraid of alkaline powder like all fled, and soon the cup becomes smooth as new!
- Q: What is the important character of Chinese made alkali?
- Hou Diping famous chemist, "Hausdorck Alchemy" founder. He has worked for China's chemical industry and has been known for his life in the world. Sodium carbonate is used extensively. Although people have been from the saline soil and salt lake in the sodium carbonate, but still can not meet the needs of industrial production.
- Q: Our home often burn porridge which put a little alkali inside, so delicious, more entrance, eat often harmful to the health of it?
- Simply said, harmful, will damage the body's internal and alkali balance, easy to get sick.
- Q: Alkali soda water
- In 1772, Joseph Plistree published a book, "Combination of Water and Gas," describing the drop of sulfuric acid on chalk, releasing carbon dioxide and encouraging people to collect gas with a bowl full of water. In 1771, the Swedish chemist Luben Bergman independently invented a manufacturing process similar to that of Joseph Plistry's discovery of carbonated water. But less successful, he managed to produce natural bubbling spring water, then think that bubbling spring is good for health. Now, carbonated water is made by pressurized carbon dioxide through water. The pressure of the pressure is stronger than the standard atmospheric pressure, so that it increases the solubility, so that carbon dioxide into the. When the bottle is opened, the pressure is released, the gas forms a bubble out, thus forming a unique bubble. The best known for carbonated water is the advantage of removing stains, such as coffee stains in coffee cups, or silver stains. It is said that the wine stains can be mixed with salt, and then add a lot of carbonic acid to remove. Carbonated water is available at the grocery store and is also very simple. To the supermarket condiment counter bought to eat soda powder. Then prepare a bottle of mineral water. Will be a drink of water cups, put a spoonful of soda powder, how much soda powder can be based on personal taste to set. If put more, too salty, some people can not stand, put less. And then filled with mineral water, pay attention to the water must be cool. Now the living standard is good, every day big fish and meat eat, the body eat into acidic, drink soda can be neutralized in the body acid and alkali balance, good for health. Drink once or twice a week, stick to it, the body will feel particularly cool.
- Q: That day, I put the alum in the water, and then I smell the gas, I would like to know the alkali is not harmful to people, right?
- In the process of hair will have a microbial acid, dough after the initiation of acid, must be added alkali, in order to produce a delicious pasta;
- Q: What are the characteristics of the composition of the base?
- Can provide electronic pairs of substances. (Some salt solution of the pH value is greater than 7, but it is not a base, such as: soda ash (sodium carbonate) Na2CO3, baking soda (sodium bicarbonate) NaHCO3, etc.)
