  • 3. Open-air drilling rig: according to the different working mechanism of crushing ore and rock, it is divided into steel rope percussion drill, drilling rig, cone drill and rotary drill. Because of low efficiency, the steel rope percussion drill has been gradually replaced by other drilling RIGS. The drill pipe drives the pneumatic impactor and the drill bit to rotate together, and the piston of the pneumatic impactor is used to impact the drill bit to break the ore and rock, which is usually used in small and medium-sized mines to drill holes with a diameter of 80 to 250 mm. The roller drill uses the rolling action of the roller bit to break the rock and is suitable for drilling holes of 150 ~ 440 mm in diameter on the hard rock. It has the advantages of high efficiency and low labor intensity, and is widely used in large and medium-sized open-pit metal mines. The drill consists of an impactor (or drill bit), a rotary mechanism, a lifting mechanism, a pressure device, a walking mechanism, a slag discharge system, a drill frame and a drill pipe. Rotary drilling machines are only suitable for drilling softer minerals and coal. The common feature of these devices is that the degree of automation is getting higher and higher, and some functions realize the application of intelligent i GPS technology on these RIGS, which realizes the automatic positioning of the boom, saves the time of field marking and positioning, improves the efficiency of the operation, and enables the operator to concentrate on monitoring the process of drilling. At the same time, more attention is paid to safety and environmental protection and the improvement of human-machine relationship. With the impact of the implementation of engine emission regulations, mobility, intelligent handling and environmental regulations Tier 3/ Euro ⅢA emission regulations, most foreign rig manufacturing companies have adopted diesel engines that meet the emission standards

    DTH drilling refers to a method where the drilling bit is located at the end of a drill string, below the surface of the ground. This technique is distinguished by the use of high-performance percussion hammers, which are positioned on the drill bit. DTH drilling involves the use of compressed air to deliver rapid impacts, breaking rock into smaller fragments. This method is particularly effective in hard rock formations, making it a preferred choice for mining operations and various drilling applications.

  • If you’re working with live wires, for example, it’s always best to err on the side of caution and use heat-resistant tape instead.

  • 2. Measure and Cut Measure the required length and width of the tape, and cut it to size using a sharp utility knife or scissors.
  • Key Benefits of Red Insulation Tape


  • Flex Tape The Ultimate Waterproof Solution


  • Another important use of butyl rubber tape is in the HVAC (heating, ventilation, and air conditioning) industry. It is used to seal and insulate HVAC ducts, pipes, and fittings to prevent air leakage and improve energy efficiency. The tape also helps reduce condensation and prevents mold growth in HVAC systems.
  • Primary Insulation helps keep the lights on.

  • In addition to its strength and versatility, Flex Seal Black Tape also boasts excellent adhesion propertiesflex seal black tape. It forms a strong bond with most surfaces, ensuring that your seals will remain intact even under extreme conditions. Whether you're dealing with extreme temperatures, moisture, or other harsh elements, Flex Seal Black Tape is designed to provide long-lasting protection.
  • Electrical insulation cotton tape is also resistant to heat, oil, and chemicals, making it suitable for use in harsh environments
  • In addition to its safety benefits, yellow safety floor tape also has a positive impact on workplace productivity. By reducing the number of accidents and near misses, workers can feel more confident and secure in their work environment. This, in turn, can lead to increased productivity and morale.
  • How Does It Work?


  • Self-amalgamating rubber tape is a versatile and reliable product that is commonly used for sealing and insulating applications. This type of tape is made from a special type of rubber that chemically bonds to itself when stretched and wrapped around an object. This unique feature makes it ideal for a wide range of uses, including automotive repairs, plumbing fixes, electrical insulation, and even temporary hose repairs.
  • Electrical tape is designed to provide a secure bond but is easily removable and residue free. Duct tape is exceptionally sticky due to its adhesive composition. The rubber-based adhesive allows duct tape to bond with various surfaces for long periods of time. Because of its extreme stickiness, residue sometimes is left behind.

  • 2. Component protection The tape can be used to protect sensitive electronic components from dust, moisture, and other contaminants.
  • In addition to its electrical insulation properties, high-voltage insulation tape also offers excellent chemical resistance, making it suitable for use in applications where chemicals may come into contact with theTape
  • Strong solvents like gasoline and turpentine can dissolve butyl tape because it’s solvent-based
  • The Basics: Pump Control Boxes

  • One of the key advantages of EPDM butyl tape is its strong adhesion to various surfaces. It can be easily attached to metals, plastics, and other materials, making it an ideal choice for sealing joints, seams, and other areas where a tight seal is required. Moreover, EPDM butyl tape is also flexible and can withstand extreme temperatures, ranging from -50°C to 120°C. This makes it suitable for use in a wide range of applications, including construction, automotive, aerospace, and marine industries.

  • In conclusion, the Arc Proof Tape is a testament to the ongoing advancements in electrical safety technology. Its introduction has ushered in a new era of protection, reliability, and efficiency in the face of potentially devastating arc flash incidents. As we continue to push the boundaries of innovation, the Arc Proof Tape stands as a symbol of our commitment to safeguarding lives and infrastructure in the electrical domain.
  • One of the primary uses of flame proof tape is in electrical and wiring applications. In areas where electrical currents are present, there is always a risk of an electrical fire occurring. Flame proof tape can be used to insulate and protect wires and cables from heat and flames, reducing the risk of a fire starting or spreading.
  • Resistance to Moisture and Solvents: Rubber adhesives often offer good resistance to moisture and some solvents. They maintain their adhesive properties even in humid or damp environments, making them suitable for applications where exposure to moisture is a concern.
