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:Is urea an inorganic salt?: Is not organic matter ah inorganic salts are present in the body and food minerals in the mineral, composed of organic matter and inorganic synthesis of the human body has been found to have more than 20 kinds of essential inorganic salts, about 4 to 5% of body weight. More (> 5g) for calcium, phosphorus, potassium, sodium, chlorine, magnesium, sulfur seven; daily dietary requirements are more than 100mg, known as constant elements. Other low content, with the modern analysis of technological progress Iron, copper, zinc, manganese, cobalt, molybdenum, selenium, chromium, nickel, silicon, fluorine, vanadium and other elements were found by atomic absorption spectroscopy, neutron activation, plasma emission spectroscopy and other trace analysis methods. But also the human body is necessary, the daily dietary requirements for the amount of μg ~ mg called trace elements.

Q:How much of the body's inorganic salts account for the weight of the body?: The inorganic salts in the human body account for about 5%

Q:Definition of inorganic salts: There are about 21 kinds of elements which have important physiological functions in the body. Among them, calcium, magnesium, potassium, sodium, phosphorus, sulfur and chlorine are more and more, and the amount of inorganic compounds is more Iron, copper, iodine, zinc, manganese, selenium, fluorine, chromium, nickel, molybdenum, silicon, tin, vanadium and cobalt content is extremely small, called trace elements .2, inorganic compounds in the general name of the salt. Formerly known as "minerals." Some elements of inorganic salts for the human essential nutrients, including potassium, sodium, calcium, phosphorus, iron, iodine and other 20 kinds of elements. With the maintenance of cells and liquid normal osmotic pressure, maintenance of neuromuscular excitement As a variety of acid system activator; constitute the ester of the base; hormones, vitamins, nucleic acid composition and regulate the body's acid and alkali balance and other important physiological functions. Increased or lack of disease, such as hyperkalemia, The explanation of the "inorganic salts" in the academic literature

Q:Do inorganic mercury salts bioaccumulate?: Yes they do bioaccumulate. Mercury builds up for years and years, and eventually sits in a residue of pure mercury. - JJ

Q:Are fruits and vegetables inactive?: 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. Apple, pipa, durian, citrus, Watermelon, kumquat, peanuts, I know so much. Oh, there are: lotus lotus which contain inorganic salts

Q:Why vegetables and fruits contain rich inorganic salts: Because they are plants! From the biological point of view, they are the nature of the organic matter into inorganic salt carrier

Q:Octopus why the lack of boron-containing inorganic salts can cause rape to flow only without fruit: Boron has a great influence on the reproductive process of plants, which can accelerate pollen differentiation and pollen tube elongation. In the absence of boron, pollen tube germination is affected, poor fertilization, which leads to the formation of seeds affected, the reduction of growth hormone produced by the reduction of growth hormone will affect the formation of fruit.

Q:Please help me!: Yes it is considered to be organic only if the compound contains carbon. Oxygen and Hydrogen have no bearing on that, for example CO2 is organic, whereas H2O is not.

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:Inorganic salt through what way into the human body: The role of inorganic salts on the human body 1. Inorganic salts in the human body is extremely uneven distribution. For example, calcium and phosphorus are mostly in hard tissue such as bone and teeth, iron is concentrated in red blood cells, iodine is concentrated in the thyroid, barium is concentrated in adipose tissue, cobalt is concentrated in hematopoietic organs, and zinc is concentrated in muscle tissue. 2. Inorganic salts are important for the structure of tissues and cells
