1.Downhole drilling machine: When drilling a downhole gun hole with a aperture less than 150 mm, in addition to the application of a rock drill, it can also be used to drill a small diameter of 80 ~ 150 mm. When drilling a gun hole with a diameter of less than 70 mm in coal or softer mineral rock, it is generally used to drill or air drill, driven by a motor (or air motor) to drill the drill pipe, and the rock (coal) chips drilled out are discharged through the spiral groove on the drill pipe.

  • HPMC is prized for its unique characteristics. In the pharmaceutical industry, it acts as a thickener, binder, and controlled-release agent in various formulations. For the food industry, it serves as a stabilizer, emulsifier, and texturizing agent, enhancing the mouthfeel and overall quality of food products. In construction, HPMC is commonly used in mortars and adhesives due to its water-retention capabilities, which improve workability and extend the open time of products. Furthermore, its application in personal care products and cosmetics such as shampoos and lotions highlights its versatility.


  • Properties of Hydroxypropyl Methyl Cellulose Ether


  • 5. Let It Sit Once the HEC is fully incorporated, allow the mixture to sit for about 30 minutes. This resting period lets the polymer fully hydrate and ensures a smooth, uniform solution.


  • Moreover, HPMC is also employed in the development of ocular preparations, such as artificial tears, due to its biocompatibility and moisture-retaining properties. Its use in these applications underscores its importance in improving patient comfort and adherence to therapy.


  • Potential Side Effects


  • In addition to its functional applications, HPMC is valued for its compatibility with a range of other substances. It can be blended with various other polymers and compounds, facilitating the creation of specialized formulations tailored to specific applications. This versatility has led to its popularity in skincare and cosmetic products. HPMC is often included as a thickening agent in creams and lotions, providing a desirable texture while enhancing the stability of the product.


  • In pharmaceuticals, HPMC is used as an excipient in oral solid dosage forms such as tablets and capsules. It can improve the dissolution rate of poorly soluble drugs and provide controlled release of active ingredients. HPMC is also used in ophthalmic formulations to increase drug retention time on the eye surface.

  • 2. Construction Industry HPMC powder is a vital component in dry-mix mortars, tile adhesives, and other building materials. Its water retention properties prevent premature drying, allowing for improved workability and adhesion. Moreover, HPMC enhances the mechanical strength and flexibility of construction materials, making them more durable and resistant to cracking.
