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:What are the main physiological functions of inorganic salts?: to maintain the organization's normal excitability

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:What are the important physiological effects of inorganic salts in cells: Composition of cells in some important compounds,

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 time when the maximum number of inorganic salts is needed: Seedling stage requires the largest amount of inorganic salts, because the seedling period is to lay the foundation for the growth period, in the strong growth period is mainly composed of synthetic organic matter.

Q:Does the milk contain inorganic salts?: Calcium, phosphorus, potassium .1L milk can provide 1g of calcium, and milk calcium and phosphorus ratio of 1.2: 1, close to human milk (human milk 1: 1), digestion and absorption rate, it can ensure that the baby's calcium Need milk milk in the very few, only 0.2mg / 100g, for the human milk 1/5, the baby, such as milk-based food feeding, the need to timely add iron and vitamin C foods such as egg yolk, liver mud, In addition, the milk also contains copper, zinc, manganese, iodine, molybdenum and other trace element

Q:I&#39;m said that with the increase of temperature the inorganic salts will decrease. Will that be correct?: Usually solubility will increase with increasing temperature but there are a significant number of exceptions which show the opposite.

Q:Several kinds of inorganic salt food sources?: Milk containing calcium, spinach iron, kelp containing iodine, oysters containing zinc, carrots containing A, tomatoes containing C, mushrooms with B1, sun can get D

Q:What to eat can promote the absorption of inorganic salts: The inorganic salt is required to enter the carrier in the cell membrane that requires the cell membrane

Q:Is the conduction of excitement on neurons related to inorganic salts?: Neurons are cells with long synapses (axons) that consist of cell bodies and cell processes. In the long axon with a layer of sheath, composed of nerve fibers, it is a small branch of the end called nerve endings. Cell bodies are located in the brain, spinal cord and ganglion, the cell processes can be extended to the body organs and tissues. The cell body is a nuclear part of the cell, its size is very different, about 4 to 120 microns in diameter. Nuclear large and round, located in the central cell, less chromatin, nucleolus obvious. There are plaque outside the cytoplasmic chromatin (formerly known as Neil body), there are many neuronal fibers.
