HSA微硅粉 – 具有卓越性能的多功能硅粉

HSA微硅粉 940

硅粉, also known as condensed silica fume or microsilica, is an ultrafine amorphous silicon dioxide that offers significant performance advantages across many industries. HSA is a world-leading manufacturer of microsilica under the brand name HSA微硅粉.

What is MICROSILICA?

HSA’s MICROSILICA products consist of sub-micron, non-porous, perfectly spherical silica particles with purity levels of 85-99%. This unique microstructure provides two key benefits:

  • Filler effect – The extremely small 0.15 μm particles act as an efficient filler material, optimizing particle packing density.
  • Chemical effect – The amorphous nature and high surface area make MICROSILICA highly reactive as a pozzolanic material.

These physical and chemical attributes allow MICROSILICA to enhance strength, 耐用性, and other critical properties in cementitious systems like concrete.

Construction Applications

In the construction sector, MICROSILICA improves performance in materials like:

  • High performance concrete – Reduces construction time while boosting structural integrity and durability.
  • Fiber cement – Used in roofing, 管道, tiles and siding to replace asbestos.
  • Gypsum board – Enhances fire resistance and core strength.

Key products include MICROSILICA 940 和 MICROSILICA 920 for concrete, fiber cement and gypsum applications in densified or undensified forms.

耐火材料

For refractory applications, MICROSILICA offers benefits like increased strength, heat resistance and service life at high temperatures. It enables complex shapes and low porosity in castables and other refractory products.

HSA’s MICROSILICA 971, 968 和 955 are purpose-made grades for advanced low/ultra-low/no-cement castable refractories.

油井固井

For oil well cementing, MICROSILICA enhances critical properties like bonding, compressive strength, fluid loss control and resistance to permeability/corrosion.

HSA Specialty MICROSILICA are designed for slurry applications requiring low density, high early strength and effective fluid loss control.

Quality and Sustainability

人血清白蛋白 emphasizes product quality through rigorous statistical process control, resulting in high silicon recovery, low impurities and stable performance. The company is also committed to sustainable practices.

With such a versatile portfolio supported by decades of industry experience, HSA MICROSILICA offers a best-in-class solution to improve performance across diverse material applications.
