For all those who are applicable. For example : the rapid growth of the girls, and more salt , calcium excretion increased, reducing absorption can lead to bone demineralization , bone dysplasia . Incidence of women , osteoporosis in post -menopausal Another example is already very high, if more salt , not only silicon carbide grit the amount of calcium , the loss of calcium also increases will accelerate its osteoporosis . In one study , the daily salt intake in postmenopausal women reduced to 4.4 grams of 10.6 grams , calcium excretion and serum calcium concentrations are greatly reduced. If you continue to re- hypertensive patients is a high -salt diet , their urinary calcium excretion than people with normal blood pressure is much higher , leading to potentially dangerous bone demineralization is also larger than normal blood pressure . Instead, eat less salt , but they can reduce urinary calcium , bone density increased.
According to WHO recommended standards, the daily amount of salt to five grams is appropriate, not to exceed 6 grams. We know that people 24 hours of discharge is 3-5 grams of salt , then the food garnet suppliers 5 grams of salt per day , it lost considerable numbers and supplements to meet the normal needs. The daily amount of salt should be limited to less than 5 grams , is not easy. This need to change our eating habits for the job . Because in our country, especially in the northern residents , the amount of salt in general ones, and more than 12 grams per day , in some places , up to 20-30 grams . People should eat salty traditional habit , all of a sudden change over, is quite difficult. But people know eat less salt can be calcium , calcium can also be no cost truth , we have gradually , appropriate to reduce the amount of salt in their daily lives , I think it can be done.
In other places , there are potassium , magnesium and sodium salts of the market, the amount of sodium salt of only 65% of such ordinary salt . If you eat this salt , the salt itself has been reduced to 1/ 3 of the . Chinese autumn stone , the main ingredient is potassium chloride, bought it fine, mix with half the salt , can also play a role in reducing salt 1/2 .
Black silicon carbide is quartz sand, petroleum coke and quality silica as the main raw material in electric arc furnace smelting. Its hardness between corundum and diamond, the mechanical strength is higher than corundum, brittle and sharp. Black silicon carbide SiC containing approximately 98.5% higher than its toughness green silicon carbide, mostly for processing low tensile strength of the material, such as glass, ceramics, stone, refractory materials, cast iron and non-ferrous metals.
