Magnesium sulfate uses magnesium oxide,magnesium hydroxide,magnesium carbonate,and magnesite as raw materials,and is decomposed or neutralized by adding sulfuric acid.At the same time,the by-product of potassium chloride production is used as a raw material,mixed with the magnesium-containing mother liquor after bromine production in proportion,cooled,crystallized and separated to obtain crude magnesium sulfate,and then heated,filtered,purified,cooled and crystallized to obtain industrial magnesium sulfate.It can also be heated,concentrated,crystallized and separated from brine or an aqueous suspension of carbonated magnesium oxide and gypsum.

When storing magnesium sulfate,whether you pay special attention to some key points,such as work clothes,protective glasses,strict operating procedures training and storage environment requirements,you can see the following introduction,so that you can better store the product and prevent danger,so as not to affect the product quality.

　　The products shall be stored in a cool and ventilated warehouse;Keep away from fire and heat sources to prevent direct sunlight;The packaging shall be sealed and stored separately from oxidant to avoid mixed storage.The storage area shall be provided with suitable materials to prevent leakage.

　　Storage method of magnesium sulfate:

　　Operation precautions,operate in a closed manner and exhaust locally.Prevent dust from being released into the workshop air.Operators need to receive special training and strictly abide by operating procedures.It is recommended that operators wear self-priming filter dust masks,chemical protective glasses,anti-virus wor

　With the development of agricultural technology,magnesium sulfate is used as a fertilizing material.Let's take a look at the specific uses of magnesium sulfate and whether it can be used as a foliar fertilizer.

　　1.Applied to soil

　　As a base fertilizer,it should be mixed with other chemical fertilizers or organic fertilizers before plowing,or mixed with refined fertilizers and applied separately.Top dressing should be applied early,applied in furrow or washed with water.The appropriate dosage of magnesium fertilizer applied to the soil is 10-13 kg per mu,and the amount converted into pure magnesium is 1-1.5 kg per mu.After one application,it can be applied after several crops,not every season.

　　2.Spray on the leaves

　　Liquid foliar fertilizer,sprayed on the leaves in the early and middle stages of crop growth.Different crops and different growth periods of the same crop require different spraying concentrations.The spraying concentration of magnesium sulfate aqueous solution sho

The color of magnesium sulfate is usually white before it changes.It is believed that its chemical reaction will cause it to change color,but this is actually caused by a variety of factors,such as geographical environment,human operations and other factors which can cause such problems.Next,we will introduce the reasons that may cause the discoloration of magnesium sulfate.

　　1,magnesium sulfate is easily soluble in water,strong activity,can improve other colors of the metal,significantly improve other colors,change the overall color.

　　2.According to the different characteristics of heavy metals,the sensitivity of magnesium sulfate is also different.

　　3.During the preparation process,ion reaction and oxidation often occur,which is active.If heavy metal elements are infiltrated,considering impurity ionization,the deformation of the lattice constant curve loses symmetry,showing an effect.

　　4.The color of magnesium sulfate is usually white,which inevitably affects the application

Magnesium sulfate is a magnesium-containing compound with the molecular formula MgSO4.It is a commonly used chemical reagent and drying reagent.It is colorless or white crystal or powder,odorless,bitter,and deliquescent.Now let's take a look at the applications of magnesium sulfate in medicine.
　　1.It can relax skeletal muscles,and has the effects of sedation,spasmolysis and reduction of intracranial pressure.It is often used in the treatment of convulsions,eclampsia,uremia,tetanus,and hypertensive encephalopathy.10%magnesium sulfate is injected into deep muscles or diluted with 5%glucose to 2%~2.5%solution.But it should be noted that direct intravenous injection or high-dose intramuscular injection is very dangerous.Generally,25%magnesium sulfate should not be used more than 15ml at a time.Attention should be paid to the patients'breathing and blood pressure.Knee reflex block is an important sign of sufficient magnesium ions.
　　2.Magnesium plays an important role in the metabolism of

　Magnesium sulfate is a common chemical and drying reagent.Because it is not easy to dissolve,and it is easier to weigh than other solutions,which is convenient for industrial quantitative control.Its function and use are explained below.
　　1.Maintain the balance of water and electricity.Intramuscular injection or intravenous injection can replenish magnesium ions in the body,which can effectively prevent and control convulsions(eclampsia);Magnesium ions directly act on uterine myocytes and can relieve uterine contraction.Adverse reactions:patients with gastrointestinal ulcers and mucosal damage are easy to absorb large amounts,causing magnesium poisoning.
　　2.Hot compress with 50%solution for external application can reduce inflammation and relieve pain.Put the gauze or absorbent cotton into 50%magnesium sulfate solution,fully soak it,take it out and apply it to the affected area,and put a warm water bag on the gauze or absorbent cotton.The oral drug concentration of 33%is conducive t
