Calcium Hydroxide: is a kind of expansive chemical product, which is very popular in the international quarrying and demolishing market.
When it is mixed with clean and cold water to be mortar and poured into pre-drilling holes of rock and concrete, it swells and exerts expansive capabilities on the hole-wall at a unit value of more than 50Mpa (500kg/cm2 .) which is strong enough to cut and crack reinforced concrete, marble and granite after a while.
Copmare to the traditional explosives, it has the following advantages:
1)Non-explosive and very safe
2)very economical and cost-effective;
3)The shape is controllable
CRACKAG can be applied to various situations:
Granite, marble, sandstone, limestone, quartzite quarrying and cutting
Precious stone quarrying
Rocks pre-splitting, fracture, cutting, demolishing and removal
Concrete structures demolition and rocks cracking when explosion not allowed
Fracture and demolition of the concrete buildings and structures
Rocks cutting for road construction.
- Q: Who can tell me what is plant alkalinity?
- (Sodium bicarbonate) (chemical formula Na2CO3) and baking soda (sodium bicarbonate) (chemical formula NaHCO3), baking soda is a solution of soda ash or crystal absorption after the carbon dioxide Of the finished product, the two are essentially no difference. Therefore, edible alkali in some places also known as baking soda (powder). 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 alkali sand
- Potassium carbonate, white crystalline powder. Density of 2.428g / cm3. The melting point of 891 ° C, the decomposition of boiling point, the relative molecular weight of 138.21. Soluble in water, aqueous solution is alkaline, insoluble in ethanol, acetone and ether. Hygroscopicity, exposure to air can absorb carbon dioxide and moisture, into potassium bicarbonate, should be sealed packaging. Hydrates have a water, dihydrate, sour things. Potassium carbonate aqueous solution is alkaline. Insoluble in ethanol and ether.
- Q: What is the difference between baking base and common base?
- The main content is not the same
- Q: What is the important character of Chinese made alkali?
- (1) NH3 + H2O + CO2 = NH4HCO3 (2) NH4HCO3 + NaCl = NH4Cl + NaHCO3 ↓ (3) 2NaHCO3 (heating) = Na2CO3 + H2O + CO2 ↑ That is: ① NaCl (saturated) + NH3 + H2O + CO2 = NH4Cl + NaHCO3 ↓ ②2NaHCO3 = Heating = Na2CO3 + H2O + CO2 ↑ Ammonia reacts with water and carbon dioxide to form a molecule of ammonium bicarbonate, which is the first step. The second step is: ammonium bicarbonate reacts with sodium chloride to form a molecule of ammonium chloride and sodium bicarbonate precipitation, sodium carbonate is precipitated because it is less soluble.
- Q: Would you like some rice when you cooked rice or millet gruel?
- Can, rice porridge plus alkali and do not add alkaline vitamin bl, b2 is almost the same, in order to taste, can be appropriate alkali, harmless to the human body
- Q: What is the use of alkali?
- Can be removed in the clothes when the clothes on the oil, you can neutralize the sour in the face, you can make the porridge easier to boil.
- 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?
- Alkali has a strong role in degreasing, you can remove the oil on the dry goods on the excess oil;
- Q: What is the role of alkali in the surface
- Nutritional analysis: 1. In the process of hair will have a microbial acid, dough after the initiation of acid, must be added to the alkali (carbonate) to acid off in order to produce a delicious pasta; And dark green vegetables due to the excessive spraying of pesticides and organic acids or sulfide, which can keep the original color of vegetables and pesticides to remove the pollution of vegetables; 3. Alkali has a strong role in degreasing, can Remove the oil on the dry goods on the raw material of excess oil; 4. Alcohol can release corn is not easy to release nicotinic acid, so that long-term consumption of corn will not be due to the lack of nicotine in corn and suffering from niacin; The disadvantage is that the food in the vitamin b1, b2 and vitamin c have a strong destructive effect, and will affect the body of certain minerals absorption and utilization, and therefore can not be abused.
- Q: What is alkali?
- What is the alkali is the ionic compound, the ionization of the anion is hydroxide (OH-), in fact, the oxygen ion acid root (which can compare sulfur and sulfur), and the anion contains only hydroxide. (Such as LiOH, NaOH, NH3 · H2O) soluble in water, alkaline earth metal ions formed in the periodic table from top to bottom gradually soluble [Be (OH) 2, the alkali metal ions or alkali ions, Mg (OH) 2 is insoluble, Ca (OH) 2, Sr (OH) 2 is slightly soluble, and Ba (OH) 2, Ra (OH) 2 is easily soluble, and other bases are in addition to TlOH and Tl (OH) Is difficult to dissolve alkali and acid metathesis reaction is also known as neutralization reaction, that is, H + + OH- == H2O
- Q: What is the alkaline powder? Baking soda? Sodium carbonate or something else?
- Baking soda is very easy to absorb the air of the air, so when not in use when the best way to retract, such as sealed cans or folder chain or milk powder cans. Use, you can use a commercially available pepper to retract, but not Add the lid, pepper cans of the hole is very easy to sprinkle the small soda.There is no pepper cans, you can also have a hole in the cloth, such as not the yarn quality curtains, mosquito nets, etc., tied tied to the general bottle, It is easy to pour out to use.If you just want a simple moisture and deodorant, you can put the small soda in the old cotton socks, and then sealed with a rope, and then any use can be
