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: The stronger the transpiration is, the faster the absorption rate of inorganic salts and water is
- wrong. Can only promote the transport up! Can not promote absorption.
- Q: are there any other foods than water and salt that have an abiotic origin (lifeless, inorganic)?
- Various minerals we need, like iron, zinc, magnesium, etc. That's it. These also are not technically foods, as the first poster said.
- Q: Why inorganic salt waterproof coating does not apply to roof waterproofing
- Inorganic salts are generally in the form of waterproof agent, generally mixed with cement quality of 3-5 percent, but now the roof is waterproof waterproof polyurethane materials are generally used, this is a new type of waterproof coating, Paint manufacturers, you can first check online!
- Q: What are the physiological functions of inorganic salts
- Maintain cell osmotic pressure and acid-base balance
- 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: What is the inorganic salt, is not the organic salt and is not the inorganic salt
- I have not come across the salt area is divided into inorganic and organic, only heard of inorganic and organic matter. Probably the organic acid metal salt.
- Q: Common inorganic salt ions will appear when the corresponding symptoms
- Zinc ion: growth and development, taste development disorders
- 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: What is the use of inorganic salts in plants? How is it discharged
- Plants need inorganic salts, just as people need trace elements, the growth of auxiliary organisms can be through the leaves of the surface of the pores, with the water discharged together
- Q: The power of the water and inorganic salts in the plant is derived from the action of the plant
- The transpiration of plants in the body of water in the form of water vapor into the atmosphere when it is a "pump" principle, it provides a vertical pull for the root of the water, while dissolved in the water in the same salt Is absorbed and transported upward, the power is derived from the transpiration of plants
