dth drill rig

The DTH hammer operates through a system of compressed air. High-pressure air is directed down the drill string, powering the hammer at the end of the drill bit. The hammer strikes the bit with considerable force, fracturing the rock immediately beneath it. As the bit penetrates further, the broken rock is then cleared from the hole by the same air stream, allowing for continuous drilling without the interruptions often associated with other drilling methods.

  • The production begins with the selection of the base polymer, which is typically a vinyl acetate-ethylene (VAE) copolymer, although other types like acrylic or styrene-butadiene copolymers can also be used. The polymerization process, where monomers are converted into polymers, is the first step. This is usually done through emulsion polymerization, where the monomers are dispersed in water with the aid of surfactants under heat and pressure. The resulting product is a liquid polymer dispersion.

It helps hold the active ingredients together and ensures that the tablet maintains its shape and integrity during storage and handling. Cellulose ether can also be used as a coating agent for tablets, providing a smooth and glossy finish.
  • Hydroxypropyl methylcellulose, commonly abbreviated as HPMC, is a semi-synthetic polymer that has found widespread use in various industries, from pharmaceuticals to food and cosmetics. One of the most notable characteristics of HPMC is its solubility in water, which makes it an ideal ingredient for formulations that require thickening, stabilizing, or controlled release properties. In this article, we will explore the chemistry behind HPMC's water solubility and discuss some of its practical applications.

  • As soon as a product is labeled as vegetarian or vegan, consumers immediately get the impression that there’s something inherently good or natural about it, or that it’s somehow better for their health. However, the recent discussions about vegetarian meat substitutes have shown that this is not necessarily true. Such is the case for HPMC hard capsules. They’re vegan, made from cellulose fiber and therefore regarded as natural.
