Potassium Carbonate Chemical Powder for Construction

Potassium Carbonate may be
monoclinic crystal, white powder, granular
crystal or prill. The relative density is 2.428
and the melting point is at 891 degree C .It is easily soluble in water forming a slightly alkaline solution. 

It is insoluble in alcohol and ether. It has strong hygroscopicity. It easily cakes and turns into Potassium Bicarbonate 

through absorbing carbon dioxide when exposed to the air for a long time.

Plastic woven bag or kraft paper bag inner with plastic bag, in 25/50 /500/800/900/1000KG net .
Handling and Storage: Store in dry and ventilated house away from moisture. Don't store in goods yards or expose to the air. 

Protect the material from rain when loading and unloading. Be sure to keep the package

dry and free from contaminant. Avoid handling and transporting together with acid substances. In the event of a fire, use water

 as extinguishing agent.

Applications :

Potassium Carbonate is used as raw materials in manufacturing electro tube, TV kinescope,

computer display. It is applied in optical glass improving clarity, strength and refractive index. It is also

applied in electrode avoiding electric arc breaking-off during welding. It is used to produce food additives like potassium sorbate, monopotassium phosphate,

etc. Potassium Carbonate is foliar spray fertilizer and a constituent of compound fertilizer. In dyeing industry, it is used to produce vat dyestuff and discharge of ice dyeing. It is absorbent removing hydrogen sulfide

and carbon dioxide; dry powder extinguisher mixed with soda; auxiliary raw material for producing alcohol

and acetone; and antiaging agent in rubber production. Its solution is used in boiling and scouring of cotton cloth and wool's degreasing. In addition, it is also used in manufacture of printing ink, photograph-drug, polyester, explosives, electroplating, tanning, ceramic, building materials, crystals and medicine.

Q:Urine in the inorganic salt content is higher than the original urine
In fact, the concentration has increased
Q:List the major electrolytes released by inorganic salts when placed in water and explain how these electrolyte?
Which "inorganic salts" are you talking about? There are hundreds!
Q:Effect of Inorganic Salts on Viscosity
possible. The inorganic salt is dissolved in water to form positive and negative ions, and the ions of the micelles are extruded to make the solubility smaller and form an increase in the viscosity. With the increase in the amount of inorganic salt, it does not have the ability to dissolve in water, there is no micelles and the molecular state exists in the water, the liquid becomes thin ...
Q:Plant needs the largest amount of the three major inorganic salts have any effect
Q:Inorganic salts in solution?
Mn or Zn. Both MnSO4 and ZnSO4 solutions are water-white. KMnO4 is purple. But you did not stipulate.
Q:What are the effects of water, inorganic salts, carbohydrates, proteins, fats and vitamins?
The main physiological function of fat: 1. The supply of human heat. (Per gram of fat oxidation can produce 9 kcal of calories, protein and carbohydrates produce more than 2 times.) 2. constitute the body's adipose tissue, adjustable body temperature, To prevent the body outside the scattered, to protect the internal organs, moisturizing the skin. 3. Dissolve nutrients. (Some do not dissolve in water and only soluble in lipids, only in the presence of fat can be absorbed by the body.
Q:What are the effects of inorganic salts on plant growth?
P: to promote the development of seedlings and flowers open, so that the fruit, the seeds mature early. Lack of performance: the plant is particularly short, leaves were green, and purple.
Q:General identification method of inorganic salts
Take the test solution, add thiocyanate solution solution, that is blood red. Fe3 + + NH4SCN → Fe (SCN) 2 + (blood red) Take the test solution, plus potassium ferrocyanide test solution, that is, white precipitate, separation, precipitation in dilute hydrochloric acid insoluble. 3Zn2 ++ 2K4 [Fe (CN) 6] → K2Zn [Fe (CN) 6] 2 ↓ (white) + 6K +
Q:Several kinds of inorganic salt food sources?
Phosphorus-rich foods: fish, lean meat, untreated cereals, eggs, dried fruits, all kinds of seeds, etc. Almost all natural foods
Q:Indicating the organic compounds and inorganic salts in the boiling point, melting point and solubility of what is the difference
Organic compounds are mainly covalently bonded, the mutual attraction between molecules is very weak, so its melting point, low boiling point, generally insoluble in water and soluble in organic solvents. Inorganic salts with ionic bonding, positive and negative ions electrostatic attraction is very strong, so the melting point, boiling point is very high, usually insoluble in organic solvents and soluble in water.
