Submarine hammer drilling, often referred to as underwater percussion drilling, is an advanced technique utilized primarily in marine construction and resource exploration. This method combines the principles of traditional drilling with hydraulic and pneumatic operations, enabling the effective penetration of hard substrates beneath the sea floor. In this article, we will explore the processes, equipment, advantages, and applications of submarine hammer drilling.

The applications of mining slurry pumps are diverse. Their primary function is to transfer slurries from the point of extraction to processing facilities. In this stage, the slurry contains valuable minerals that need to be refined and extracted. Slurry pumps are also crucial in the dewatering process, where the goal is to remove excess water from extracted materials. This not only improves the efficiency of material handling but also protects the environment by reducing the risk of contaminated water discharge.

Una de las funciones más importantes de los chocks es brindar estabilidad. Durante el proceso de laminado, las fuerzas ejercidas sobre el metal pueden ser extremas. Los chocks aseguran que los rodillos permanezcan en la posición correcta, evitando desplazamientos que puedan afectar la calidad del producto final. Además, una alineación inadecuada puede provocar una distribución desigual de la presión sobre el metal, lo que puede resultar en defectos o incluso en daños a la maquinaria.

  • Titanium is one of the most common metals on earth, but it does not occur naturally in this elemental form. TiO2, also known as titanium (IV) oxide or titania, is the naturally occurring compound created when titanium reacts with the oxygen in the air. As an oxide, titanium is found in minerals in the earth’s crust. It is also found with other elements, including calcium and iron.

  • CSPI says it might reconsider its rating if specifications for food-grade titanium dioxide in the U.S. are updated to ensure nanoparticles are minimized, and new studies are conducted to assess its capacity to cause cancer or other health problems. 

  • After the precipitate has been isolated, the next step is to dry and weigh the sample. This is done by heating the precipitate in a furnace to remove any remaining solvent and moisture. Once the sample has been dried, its weight is measured using an analytical balance.
  • Particle Size and Shape
  • In the micronization stage, TiO2 particles are reduced to submicron sizes. This can be achieved through various milling techniques, including ball milling, media milling, or jet milling. These methods use mechanical action to break down larger particles into finer ones, ensuring that the TiO2 meets the stringent requirements for applications that need high-purity, small-particle-size pigments.

  • Different dermal cell types have been reported to differ in their sensitivity to nano-sized TiO2 . Kiss et al. exposed human keratinocytes (HaCaT), human dermal fibroblast cells, sebaceous gland cells (SZ95) and primary human melanocytes to 9 nm-sized TiO2 particles at concentrations from 0.15 to 15 μg/cm2 for up to 4 days. The particles were detected in the cytoplasm and perinuclear region in fibroblasts and melanocytes, but not in kerati-nocytes or sebaceous cells. The uptake was associated with an increase in the intracellular Ca2+ concentration. A dose- and time-dependent decrease in cell proliferation was evident in all cell types, whereas in fibroblasts an increase in cell death via apoptosis has also been observed. Anatase TiO2 in 20–100 nm-sized form has been shown to be cytotoxic in mouse L929 fibroblasts. The decrease in cell viability was associated with an increase in the production of ROS and the depletion of glutathione. The particles were internalized and detected within lysosomes. In human keratinocytes exposed for 24 h to non-illuminated, 7 nm-sized anatase TiO2, a cluster analysis of the gene expression revealed that genes involved in the “inflammatory response” and “cell adhesion”, but not those involved in “oxidative stress” and “apoptosis”, were up-regulated. The results suggest that non-illuminated TiO2 particles have no significant impact on ROS-associated oxidative damage, but affect the cell-matrix adhesion in keratinocytes in extracellular matrix remodelling. In human keratinocytes, Kocbek et al. investigated the adverse effects of 25 nm-sized anatase TiO2 (5 and 10 μg/ml) after 3 months of exposure and found no changes in the cell growth and morphology, mitochondrial function and cell cycle distribution. The only change was a larger number of nanotubular intracellular connections in TiO2-exposed cells compared to non-exposed cells. Although the authors proposed that this change may indicate a cellular transformation, the significance of this finding is not clear. On the other hand, Dunford et al. studied the genotoxicity of UV-irradiated TiO2 extracted from sunscreen lotions, and reported severe damage to plasmid and nuclear DNA in human fibroblasts. Manitol (antioxidant) prevented DNA damage, implying that the genotoxicity was mediated by ROS.
