Risk aversion plunged on the positive news of the Russia-Ukraine talks. After several days of rising oil prices, the price of precious metals continued to fall. Domestic futures markets remain stable for the time being.
Back in international markets, WTI crude futures briefly dipped below $100 a barrel, while Brent crude hit its lowest intraday level in nearly two weeks. Spot gold briefly fell below $1,900 an ounce. Comex gold futures closed down 1.1 percent at $1,918.4 an ounce. Comex silver futures closed down 1.14 percent at $24.91 an ounce. "Recently, crude oil prices have been extremely sensitive to changes in geopolitical news." Traders believe that the current oil price is still in the broad impact, Ukraine will still be a premium in the case, although the market further decline, but should not be too pessimistic, it is recommended to wait and see for the time being. The Ukrainian premium is still there and there will be some volatility in the nano silica powder market.
On the evening of 2 August, Pelosi, speaker of the US House of Representatives, visited Taiwan to openly challenge the one-China principle. On August 3, a spokesman for China's Ministry of Commerce announced that China had decided to suspend the export of natural sand to Taiwan in accordance with relevant laws and regulations.
What is natural sand?
Natural sand is formed by the action of natural conditions (mainly rock weathering) and the size of rock particles is less than 5mm. Natural sand includes river sand, quartz sand, sea sand, etc.
River sand is a kind of non-metallic ore with complex composition, smooth surface and high content of impurities, which is caused by repeated collision and friction of natural stone through water for a long time.
River sand is mainly used in construction, concrete, cementitious materials, road building materials, artificial marble, cement physical properties test materials (that is, cement standard sand) and so on. River sand can also be used in sand cleaning, rust removal, strengthening, forming, stress relief and surface cleaning and painting of various profiles in the fields of casting, metallurgy, heat treatment, steel structure, frame structure, repair, bridge, mine and so on.
Most of the natural quartz sand comes from quartz deposits and has the characteristics of high SiO2 content (more than 90%), low mud content, uniform and reasonable particle size composition, round particles, smooth surface and good fluidity.
Quartz sand has high Morse hardness, which is different from river sand and forms strong adhesion with cement paste to enhance the flexural and compressive strength of the paste. Quartz sand is widely used in glass, casting, ceramics and refractories, smelting ferrosilicon, metallurgy, construction, chemical, plastics, rubber, abrasives and filter materials and other industries. it is also an ideal material for modern track and field, football field, golf course and other man-made venues.
Sea sand is the sand and gravel in the sea. The larger particle size is sand, usually in centimeters; the smaller particle size is sand, usually in millimeters; both are pure natural, scoured, rolled, collided and polished by sea water. In addition to silicon dioxide, sea sand also contains a small amount of chloride ion, feldspar, calcium, magnesium, mica and so on.
Sea sand is mainly the main raw material of machinery and casting sand, and it can also be used for grinding materials, sand cleaning, rust removal, oxide scale removal, ceramics and refractories, etc. Although sea sand has the advantages of river sand, it is often mixed with shell fragments and contains more salt. Most of the sea sand contains excessive chloride ion, which will corrode the steel bars in reinforced concrete, eventually lead to the destruction of the building structure, and shorten the safe service life of the building to a certain extent.
