Product Description:

This product is lumpy substance, its surface is a little deep gray, has slight nasty smell. It can produce acetylene gas when met water, it can burn when meets fire. The acetylene gas mix with air will form explosive gas (explosive range of acetylene gas in the air is 2.3% - 81%).

11. Packing

50kg or 100kg iron drum

 

Cautions during transportion:

The packing must be kept in good condition and the goods should be stored in a dry,cool and ventilated place.It should be separate from the cargo can burn and acid.It should avoid meeting water and moisture.It should give off the acetylene in iron drum before storing in warehouse. Rolling drums,heavy putting down and colliding are not allowed to avoid the spark leads to explosion.

Q:What are the important physiological functions of inorganic salts in cells
Inorganic salts are important for the structure of tissues and cells. Hard tissues such as bones and teeth are mostly composed of calcium, phosphorus and magnesium, and soft tissue contains more potassium. The inorganic salts in the body fluids regulate the permeability of the cell membrane, control the moisture, maintain normal osmotic pressure and acid-base balance, and help transport the common elements to the whole body, participate in nerve activity and muscle contraction. Some are inorganic or organic compounds that are involved in many important physiological functions of constituents, hormones, vitamins, proteins and nucleic acids that make up enzymes, or as activators of various enzyme systems. For example: to maintain the heart and brain activity, to help the formation of antibodies, play a useful role in the human body.
Q:What are minerals and trace elements?
Minerals Trace elements are inorganic salts, which are widely found in nature - soil, sea water, animals, plants. It is to maintain the normal life of the human body indispensable. They are both the body of the composition, but also the activities of life participants and regulators, and therefore known as the elements of life, and they are the body can not synthesize their own nutrients.
Q:Determination of the existence of inorganic salts in the soil, in the filter, should pay attention to the matter
Filter should pay attention to is a "paste, two low, three by".
Q:how come inorganic salts increase surface tension of water?
Surface film tension is the property of a liquid by which it acts as if its surface is a stretched elastic membrane. This tension allows insects to stand on the water’s surface. Surface film tension is caused by the attraction of water molecules to each other; in addition, the surface molecules are attracted to the underlying molecules. The amount of surface film tension is affected by both temperature and dissolved substances. An increase in temperature lowers the net force of attraction among molecules and so decreases the surface tension. An increase in dissolved organic substances also lowers the surface tension However, an increase in dissolved inorganic salts causes a rise in surface tension - increases the attraction of the surface molecules for the underlying molecules.
Q:What is the relationship between inorganic salts and minerals?
Generally speaking, inorganic salts, including minerals, inorganic salts are not minerals. Some inorganic salts can be soluble in water and some can not, the vast majority of minerals do not dissolve in water, otherwise the rain on the rocks are not dissolved Is it gone?
Q:What is the difference between inorganic and inorganic salts?
Humus: refers to the biological decomposition of the remaining rich in a large number of beneficial effects on the soil containing the material, but also the whole ecosystem has a direct positive effect.
Q:The application of various inorganic salts in the human body?
Protein synthesis, nerve conduction, muscle contraction, body temperature regulation, complete cell maintenance and energy metabolism are inseparable from the magnesium.Many studies have confirmed that people lack of magnesium, often headache, irritability, emotional stress, limb weakness, depression insomnia, Children will grow and develop obstruction.Human blood levels of the body if the sudden decline, can lead to arrhythmia or coronary heart spasm, decreased immunity, women will appear dysmenorrhea.
Q:The content of inorganic salts in the body
Inorganic salts are inorganic compounds in the salt, formerly known as minerals, the body has found more than 20 species, including constant elements of iron, zinc, selenium, molybdenum, chromium, cobalt, iodine 8. If you pay attention to diet diversification, eat Animal fat, eat brown rice, corn and other coarse grains, do not eat too much refined flour, can make the body of inorganic salt to maintain the normal level should be.
Q:Inorganic salt of the inorganic salt function
Participate in and maintain the metabolic activity of the organism.
Q:Cells in the water, inorganic salts, protein, lipid
Plus a "so" on the right, because there are many other compounds in the cell
