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:How do inorganic salts enter the water?
Many of these materials enter the water through natural channels---minerals, salts and the like come from exposure to rocks, dirt and other inorganic materials.
Q:Simmons citrate medium contains primarily inorganic ammonium, potassium, and sodium salts, plus organic?
Simmons Citrate Medium
Q:What is the lack of inorganic salts for children?
Zinc is present in a large number of enzymes, such as carbonic anhydrase, respiratory enzymes, lactic acid dehydrogenic acid, superoxide dismutase, alkaline phosphatase, DNA and RNA polymerase, etc., are nucleic acids, proteins, carbohydrates Synthetic and essential ingredients for the use of vitamin A. With the promotion of growth and development, improve the role of taste. Zinc deficiency occurs when the taste is poor sense of smell, anorexia, slow growth and mental development is lower than normal performance. Zinc can often eat zinc-rich foods: such as protein zinc, oysters, walnuts, egg yolk, seafood and so on.
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:The lack of symptoms and food sources of several inorganic salts
Food sources of inorganic salts containing calcium Source: dairy products, beans, cereals, kelp and so on. Source: seafood, etc. Food of iron-containing inorganic salts Source: Fruits Containing iodine-containing inorganic salts Source (trace): seaweed, jellyfish, corn, mussels, etc. Zinc-containing inorganic salt food sources (trace): animal liver (viscera), fruit, peanuts, etc.
Q:Determination of the existence of inorganic salts in the soil, in the filter, should pay attention to the matter
Two low: filter edge is lower than the edge of the funnel;
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:After a lot of sweating, the amount of drink with inorganic salt drink right?
It is best to drink this kind of drink, which contains sodium and potassium, and when the body after a lot of exercise will consume a lot of potassium, leaving the body feel weak, this drink can quickly add the body Electrolyte, need to note that before the exercise 1-2 hours, during exercise and after exercise have to drink
Q:Inorganic salt of the inorganic salt function
Although inorganic salts in the cell content is relatively small, but there are many important role. Ca2 + is the animal bone and teeth (containing CaCO3) composition, and blood coagulation and muscle contraction has a regulatory role, if the content is too low, the animal will appear muscle twitch. K + is a variety of enzyme activator, for the plant starch and protein synthesis and animal nerve impulse conduction and muscle contraction also plays an important role. Fe is a component of hemoglobin and cytochrome, and iron-containing enzymes are indispensable when chlorophyll is formed in plants. Another example is Na + for animal heart beat, nerve excitement is indispensable. The various inorganic salts dissolved in the cells have a certain total concentration, such as human body fluid concentration of 0.9%, frogs of 0.65%, which for maintaining cell osmotic pressure, so that cells maintain a certain shape has an important role, too high or Too low will lead to cell due to water or dehydration to change the cell morphology. There are also a number of buffering systems in the body, which are a group which has a neutralizing effect on the added acid or base so that the pH does not change significantly and therefore plays an important role in maintaining the acid-base balance of the cells.
Q:The power of the water and inorganic salts in the plant is derived from the action of the plant
Capillary siphon, as well as leaf water transpiration power.
