Highlights We investigate the origin of a laminated organic-rich chert formed at the PC–C boundary. It consists of non-annual couplets composed of organic and siliceous sediment. The δ 30 Si isotopic values indicate a marine, non-biogenic silica source of the chert. Chert formed in 2-steps, first sub-sea salt dissolution triggered silica …

A cutting force model was developed from silica/phenolic composites for mill-grinding process. The experimental was carried out on silica/phenolic material and found that the cutting force decreased significantly with the increase of cutting speed, whereas the same was found increased with the increase of feed rate and cutting depth.

A competent person in the company has the authorization to eliminate or minimize silica dust if they identify silica dust hazards during the day. Another measure used is the Action Level. An action level is a concentration of airborne respirable crystalline silica of 25 micrograms, calculated as a time-weighted average over an 8-hour period.

The objective of this brief document is to report data of a preliminary analysis of several quartzite and silica-sand samples presented by Dolphin International L.L.C., the …

The existing research about ductile grinding of fused silica glass was mainly focused on how to carry out ductile regime material removal for generating very "smoothed" surface and investigate the machining-induced damage in the grinding in order to reduce or eliminate the subsurface damage.The brittle/ductile transition behavior of optical glass …

Oman is setting up an industry that takes silica from sand and rocks and processes it into a premium product – polysilicon. The crystalline substance is a key raw material for making solar panels and …

Studies reporting the findings of exposure to crystalline silica dust during concrete finishing in construction settings are scarce due to the dynamic nature of the activity and the existence of many confounding factors. ...

are at risk for significant crystalline silica exposure. Crystalline silica commonly occurs in nature as the mineral quartz, and is found in granite, sandstone, quartzite, various other rocks, and sand. Workers who inhale very small crystalline silica particles are at risk for silicosis — an incurable, progressively disabling and

Ultrasonic vibration-assisted micro end grinding (UAMEG) is a promising processing method for microparts made of hard and brittle materials. The surface quality of the workpiece in UAMEG is important, as it influences the performance of the finished part to a great extent. However, the surface finish is governed by many factors, and its …

There is a demand for high-efficiency and high surface integrity grinding of fused silica. Ductile grinding is an ideal method for producing a mirror finished surface on hard and brittle materials to significantly decrease polishing time. However, the fused silica is still difficult to ductile grind because of its high brittleness. A creep feed taper grinding …

Based on micro-indentation mechanics and kinematics of grinding processes, theoretical formulas are deduced to calculate surface roughness (SR) and subsurface damage (SSD) depth. The SRs and SSD depths of a series of fused silica samples, which are prepared under different grinding parameters, are m …

high amounts of silica. When you cut or grind these products, you are being exposed to silica if measures are not taken. Although most diseases associated with silica exposure are not curable, they are preventable. Identify controls Here are some measures you can take to reduce the amount of silica in the air when cutting or grinding.

Fracture defects such as subsurface cracks caused by grinding are the manufacturing defects that are most likely to cause laser irradiation damage and must be completely removed in the subsequent polishing process so that the fused silica optics can withstand the irradiation of high-power lasers [1,2,3,4,5,6].The polishing process is …

The use of the QPREP X-Tap fixation system allows efficient and non-residual changing of the grinding paper between the different grinding stages. Self-adhesive QPREP silicon carbide grinding paper is available in diameters of 200 / 250 / and 300 mm and in 13 different grain sizes.
