5.FAQ

1, how about your packing?

My main packing is 25kg or 1000kg PP PE or kraft bag , with or withour pallets,with or without anticaking. We also can make packing and shipping mark are your ask, such as 50kg/50bl bag.

2, ‍how long time you can make the shipping?

We can make the shipping within 5-10day after confirm the order.

‍3, why you buy from me?

We have stable quolity and price, not best quolity and price. It is not true for best quolity and best price. Our factory is manufacture according the BP USP and FCCIV terms. We have in this line for more than 8 years. We are one of the biggest exporter from Qingdao port.

Q: and what are the kinds of organic compounds?..pls. help me abt. this..thanks!..(^_^): I think organic compunds are anything with Carbon(C), although I really don't know.

Q: What is the inorganic salt: The main sources of various inorganic salts and the lack of the main performance (1) sodium sodium is the main ingredient of salt.China's nutrition society recommended adults over 18 years of age sodium intake of 2.2 grams per day, the elderly should take light food Sodium is commonly found in a variety of foods. The main sources of sodium are sodium, soy sauce, pickled foods, smoked foods, salty foods, etc. (2 Calcium is an important part of bone. Disease, osteoporosis, etc .. China Nutrition Society recommended adults aged 18-50 adult calcium intake of 800 mg per day; 50 years of age in the elderly 1000 mg.General calcium-rich foods are milk, yogurt, Oatmeal, sea cucumber, shrimp, wheat, soybean meal, soy products, lily, etc. (3) magnesium is the necessary elements to maintain the structure and function of bone cells.Magnesium deficiency can lead to nervous tension, emotional instability, muscle tremor and so on. (4) Phosphorus is an important part of the composition of bones and teeth. (4) Phosphorus is an important component of bone and teeth. (4) Phosphorus is an important component of bone and teeth. Severe phosphorus deficiency can lead to anorexia, anemia, etc. China Nutrition Society recommended adults over 18 years of age the appropriate intake of phosphorus is 700 mg. Common phosphorus-containing foods are lean meat, eggs, milk, animal offal, kelp, Nuts, coarse grains. (5) Iron is the most content of trace elements in the human body, iron and the human body's life and its health are closely related to iron deficiency will lead to iron deficiency anemia, immunity decreased. China Nutrition Society recommended 50 years old More than men's or women's iron daily intake of 715 mg. Common iron-rich foods are animal liver, kidney, caviar, lean meat, potatoes, wheat bran.

Q: For patients with ulcerative colitis, which inorganic salt foods can eat?: Inorganic salts with water-soluble and can not oxidize the combustion and other properties, plays a role in maintaining the body's acid-base balance and metabolism.

Q: What is inorganic salt? Lemon flavor, citric acid, is it an inorganic salt?: Although the inorganic salt in the cell, the body content is very low, but the effect is very large, if the attention of diet diversification, eat less animal fat, eat brown rice, corn and other coarse grains, do not eat too much refined flour, Salt to maintain the normal level of citric acid is an important organic acid, also known as citric acid, no ...

Q: Can inorganic salts act as stabilizers for emulsified asphalt?: can. The general use of calcium chloride and ammonium chloride more stable emulsifier

Q: Does the lack of inorganic salts cause convulsions?: The lack of important substances in the salt body is indeed the use of salt to protect the health of important substances than the calcium and phosphorus main body bone calcium blood coagulation muscle contraction and nerve cell regulation very important phosphorus calcium with the same function of food are preserved phosphorus body lack of calcium muscle spasms Can be rash dyspnea gastrointestinal paralysis and other body no phosphorus calcium calcium phosphate can be used to make bone calcium and phosphorus with a reasonable reason to play its role in the use of salt my body's non-essential body about 50 grams of salt according to 0 --- 2 5 grams To follow the excreta outside the body need to be added or otherwise the body of the production capacity of the body is extremely lack of salt can be fainting disease to speed up or even cause muscle weakness in the iron content and its role is not important in vivo iron deficiency anemia and other iron deficiency

Q: The lack of three major inorganic salts can cause symptoms in the plant: Nitrogen: to promote cell division and growth, so that leaves grow lush. Lack of performance: plant thin and thin, leaves yellow, severe leaves were light brown.

Q: What is the relationship of electronegativity and the solubility of a inorganic salts?Does the solubility increase when electronegativity decreases or vice-versa? or neither...: The higher the electronegativity, the stronger the acid would be... Therefore it would be more soluble. take NaCl (common table salt) as an example. The difference between Na's electronegativity and Cl's electronegativity is very high so NaCl is a very soluble salt. The only exception is HF - it is a weak acid - it dissociates very weakly because O-H bonds cannot break H-F bonds which are very strong.

Q: Does the plant roots absorb inorganic salt ions must be active: Plants absorb inorganic salts and do not necessarily absorb water. Plants absorb moisture and absorb inorganic salts are two relatively independent processes. Plants absorb moisture through the infiltration of root cells to absorb water, the process is essentially free of water diffusion process, neither the carrier nor the need for energy; and plant absorption of inorganic salts is carried out by means of active transport, This process requires the carrier and consumes the energy generated by cell metabolism. Of course, plant water absorption and absorption of inorganic salts are a certain association, inorganic salts to be dissolved in water to be absorbed, and inorganic salt ions in the transport of plants can not be separated from water.
