Specifications of Calcium Hydroxide

Calcium hydroxide is roughly made of lime after processed and refined to remove hazard matter like metallic matter.

1.Molecular formula: Ca (OH)₂

2.Molecular weight: 74.096

3.Physicochemical Property:

Soft and delicate white powder with a density of 2.24 and a stacking volume of 0.6-0.8. After 500, hydrate water will lose to become calcium oxide, which absorbs carbon dioxide in the air to form calcium carbonate that can be dissolved in acid instead of water and alcohol.

4.Feature:

High activity, loose structure, great purity (able to be analytically pure), white, fine granulate with few content of foreign matter

5.Usage

The produce is widely used in synthesis of medical drug, food additive, hi-tech biological material HA, VC phosphonolipide used as feed additive, food arum, calcium agent, additive for candy manufacturing industry of calcium naphthenate, calcium lactate and calcium citrate, water processing and other high-grade organic chemical industry

Q: What is white alkali?: White alkali is sodium carbonate, is a hydrolysis of alkaline water content of crystalline water carbonate, caustic soda, caustic soda, caustic soda, in the chemical raw materials store can buy

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 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: 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?: Alkaline powder can treat burns. If the scald area pony immediately coated with alkaline powder, and then drop a few drops of water, alkali powder will be dissolved immediately after the water. Was burned parts of the beginning of the alkaline powder coated with a sense of burning, and after a while feel very comfortable ice, like the heat burned alkaline powder is like, so repeated several times can reduce the pain and trauma burns. If the area of burns larger, can be soaked with alkali powder soak for about half an hour or an hour.

Q: What to do with the wall: Room regardless of the new wall or the old wall, will be due to excessive moisture with alkalization problems, especially in the wet environment, is the root cause of the quality of paint. In the brush before painting a layer of water-based sealing primer can not only save the cost of decoration, from the long-term and decorative effect point of view, brushing primer more effective with less. This kind of primer excellent sealing so that it can effectively resist the penetration of alkaline substances in the wall to prevent the precipitation of water soluble salt, to prevent the wall back to the alkali. At the same time, good adhesion of the primer makes the wall more smooth, so that the finish is easier to brush, reducing the amount of topcoat. In this way, the wall to avoid the paint disease, but also conducive to a longer time to keep the brushing effect. Also note that the primer and topcoat is best to use the same brand or with the matching paint to prevent the primer and the paint between the surface of the chemical reaction. Please read carefully the type or model of the primer (or finish) indicated in the packaging instructions.

Q: What is the use of alkali?: From acid and alkali combined effect

Q: What is the role of alkali in the surface: (Sodium bicarbonate) (chemical formula Na2CO3) and baking soda (sodium bicarbonate) (chemical formula NaHCO3), baking soda is a solution of soda ash or crystal after the absorption of carbon dioxide after the finished product , The two are essentially different.Therefore, the consumption of alkali in some places also known as baking soda (powder). Edible alkali was solid state, round, color white, soluble in water. Alkaline is not a common Seasoning, it is just a food loose agent and meat tenderizer, can make dry goods raw materials quickly rise, soften the fiber, remove the dough's sour taste, the appropriate use for food can bring excellent color, Shape to enhance people's appetite. Alkaline used in a large number of food processing such as noodles, bread, bread, etc.

Q: The commonality of the base: alkali and acid reaction, the formation of salt and water (such reactions are commonly referred to as neutralization reaction)

Q: And how to do the big face ah?: In fact, the biggest drawback of alkali is the steaming steamed bread turned yellow does not look good, but the big baked bread is very delicious ah ~ I feel better than the normal bread ~ ~ I think their family to eat, but also eat only The most important

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
