(1) When using the drilling rig to drill, the driver should be placed in the drilling position, so that the front end is against the rock, and the distribution should be careful to let the drilling rig move forward, so that the drill bit touches the rock; When opening the hole, first quietly let the drilling rig drive, when the drill rod is in place in the rock, it is allocated to the full open position.
(2) Before starting the drilling rig, check whether the charging pressure of the accumulator is normal; Check whether the scouring water pressure and the lubricating air pressure can be; Check whether there is sufficient lubricating oil in the lubricator, and whether the oil supply is appropriate; Check the reverse tendency of the oil pump motor. (3) If the drilling rig cannot open the hole smoothly, it should first assign the rock drill to retreat, and then let the rock drill move forward to open the hole from the beginning.
(4) When replacing the drill bit, the drill bit should be gently pressed against the rock, so that the motor of the drill can be reversed to complete the sensitive unloading head.
(5) The inspection of hydraulic components can only be prevented under the condition of pole cleaning, and after the connecting tissue is removed, it must be quickly plugged with the cleaning tightly matched plug. Before the repaired rock drill is used from scratch, it is necessary to circulate the hydraulic oil into the oil circuit to wash the components of the hydraulic system.
(6) The oil level and oil supply of the lubricator should be checked regularly; The gear with reverse structure is regularly filled with high-temperature grease; Check the oil level in the lubricating oil tank regularly and remove the dirt in the oil tank

Brand reputation plays an essential role in the pricing of drilling machines. Well-established brands with a history of producing high-quality, reliable equipment often command higher prices than lesser-known manufacturers. However, investing in a reputable brand can provide long-term benefits, including better after-sales support, availability of spare parts, and a warranty. Cheap equipment might save money in the short term, but it could lead to higher maintenance costs and lower productivity over time.

  • Titanium dioxide is often listed in the ingredients list on the product label when used in home, beauty and personal care products.

  • As a critical component in these diverse applications, the supply chain of micro TiO2 is vital
  • One of the most remarkable aspects of titanium dioxide is its versatility. It is commonly used as a pigment in paints, coatings, and plastics due to its excellent whiteness, brightness, and opacity. In these applications, titanium dioxide helps to create vibrant and long-lasting colors while also providing durability and resistance to weathering.
  • The manufacturing process of titanium dioxide typically involves mining ilmenite, rutile, or anatase from natural sources, followed by conversion into TiO2 through various chemical processes. The resulting TiO2 can then be further processed to achieve different particle sizes and coatings that optimize its performance in specific applications. For instance, TiO2 used in sunscreens is often coated to enhance its effectiveness in blocking UV rays without causing skin irritation.

  • 2. Barite calcination method A solution of barium sulfide is prepared. The sulfuric acid and zinc oxide are reacted, purified by adding potassium permanganate and zinc powder, and compressed to obtain a zinc sulfate solution. Then, the prepared barium sulfide solution is mixed and subjected to a metathesis reaction to obtain a mixture of zinc sulfide and barium sulfate, and then the precipitate is subjected to pressure filtration, calcination, wet grinding, drying, and pulverization to obtain a zinc white product.

  • The number '20298' in this context could represent a significant statistic or a unique identifier, emphasizing the magnitude of the titanium dioxide production landscape. It symbolizes the vast network of facilities that operate tirelessly to meet global demand for this versatile compound. Each of these factories, whether large or small, plays a crucial role in the supply chain, ensuring a steady flow of high-quality titanium dioxide.
  • In a 2017 study published in Scientific Reports, researchers exposed rats to human-relevant levels of E171 to examine the effects of intestinal inflammation and carcinogenesis. They saw that “a 100-day E171 treatment promoted colon microinflammation and initiated preneoplastic lesions while also fostering the growth of aberrant crypt foci in a chemically induced carcinogenesis model.” They continued: “Stimulation of immune cells isolated from Peyer’s Patches [which are clusters of lymphoid follicles found in the intestine] showed a decrease in Thelper (Th)-1 IFN-γ secretion, while splenic Th1/Th17 inflammatory responses sharply increased,” researchers wrote. “A 100-day titanium dioxide treatment promoted colon microinflammation and initiated preneoplastic lesions.” The scientists concluded: “These data should be considered for risk assessments of the susceptibility to Th17-driven autoimmune diseases and to colorectal cancer in humans exposed to TiO2 from dietary sources.”
