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.

  • HPMC is a non-ionic, water-soluble polymer made by reacting cellulose with propylene oxide and methyl chloride. This modification provides HPMC with enhanced solubility in cold water, viscosity, and film-forming properties. As a derivative of cellulose, HPMC exhibits unique properties, including excellent thermal stability, emulsification abilities, and thickening power, making it versatile across various applications.


  • Hydroxypropyl Methylcellulose (HPMC) is a versatile synthetic polymer that plays a crucial role in a wide array of industries, from pharmaceuticals to construction. The growing demand for this compound has given rise to specialized manufacturing facilities known as HPMC factories. These factories are essential in ensuring a consistent supply of high-quality HPMC products, catering to various industrial needs.


  • The degree of substitution (DS) is a critical parameter in HPMC synthesis. It refers to the average number of hydroxyl groups on the cellulose molecule that are replaced by hydroxypropyl and methyl groups. A higher DS generally leads to increased solubility in water and enhanced viscosity in solution, making the polymer more effective for various applications. Manufacturers often tailor the DS to suit specific requirements, allowing for a range of HPMC products with differing properties.
