Efficient utilization technology is asbestos tailing chemically to obtain fine magnesium hydroxide from the tailings, ultra-fine silica (silicon dioxide), iron hydroxide, which is discharged sludge can be made lightweight insulation spacer Hot plate. The technology is applied in the pilot production line of 1000 tons of asbestos tailings. The product quality is stable, the yield is 88%, the prepared magnesium hydroxide content is 98% or more, the whiteness is 93.5, and the specific surface area is 76 grams per square meter, pore volume of 0.62 grams per cubic meter, average particle size of 0.96 microns; prepared silica content of 98% or more (dry basis), whiteness of 94.6, specific surface area It is 325 g per square meter, the bulk density is 0.12 g per cubic centimeter, the pore volume is 1.12 g per cubic meter, and the prepared iron hydroxide content is 98% or more. As a new flame retardant filler for plastics, rubber, cables, coatings and other products, magnesium hydroxide and silica, which are widely used in silicone rubber, advanced ceramics, paper, plastic film, etc., have large market demand, and most of China still Need to import.
It is understood that for every ton of finished asbestos produced, it will produce 25 to 27 tons of tailings and serpentine gravel. China's current annual output of asbestos is more than 340,000 tons, and the annual output of tailings amounts to 8.16 million to 9.18 million tons. The ground also pollutes the environment. After 1 ton of asbestos tailings is processed by this technology, it can produce 0.35 tons of ultrafine magnesium hydroxide, 0.32 tons of ultrafine silica, 0.2 tons of iron hydroxide and 0.09 of lightweight building materials. According to the current market price of the products, the output value per ton of tailings can be 6650 yuan. After deducting the processing cost, the profit and tax can be 2150 yuan. For example, Akex County, one of the major asbestos producing areas in China, produced 170,000 tons of asbestos last year and about 4.25 million tons of tailings. If 10% can be used for treatment, it will create profits and taxes of 914 million yuan. Therefore, the promotion of the project will bring huge economic and social benefits to the asbestos industry.

Silicone Cup Lids

About silicone lids for cups
As we know,each cup has a lid,most of cup lid are made of glass or ceramics,but we also know that they break easily.And sometimes we need find something replace glass cup lid,and keep the cup beautiful.
