High purity hydrated lime for water treatment

1. Features

1). Lower cost for water treatment

2). Widely range of application

3). Aid to coagulate well

2. 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 to adjust up water PH value of water supply plant

3. Quality Specification

Executive Standard QB1001-2011

Item	Index
	High purity			Refined
Appearance	white or grey white powder
Ca(OH)2(%) ≥	95%	92%	90%	88%	80%	70-75%
Mesh	400	200	200	200	200	150
Hydrochloric acid insoluble, %	0-0.7			0-1.0

4. How to Use

Wet dosing: Firstly, make it up to 5%-10% solution and continuously mechanical stir. Add to waste water after it completely mixed into suspension & turbid liquid until the PH value come to target value

Dry dosing: add it directly to the reaction pool, control of its dosing through the ph value. This method is suitable for dealing with strong acidic sewage; adjust the ph value to rough though its strong alkalinity.

5. Packing, Storage and Transportation

Packed with 25 kgs woven bag or paper bag.

Stored in dry ,cool and ventilate place, it will keep good for 6 months.

Q:How to go to the base of the teapot: With a rinse rinse just fine

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: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 alkali active aggregate?: The active aggregate is the active mineral fine admixture can promote the cement hydration product further transformation, improve the hardened concrete pore structure, improve the concrete compact performance

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: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 is white alkali?: White alkali is dough (soda, soda ash), scientific name sodium carbonate, chemical formula Na2CO3.

Q:What is the big base?: Large alkali is the main component of sodium carbonate.

Q:And how to do the big face ah?: Add some vinegar for some time. You can use the yeast hair, so that will not produce such a problem.

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.
