Silica particles are highly prone to agglomeration due to van der Waals forces and electrostatic interactions, leading to compromised performance. How can technical means achieve efficient deagglomeration and uniform dispersion? Ultra-fine silica dispersion equipments like jet mills has emerged as a key solution for the industrial application of nanomaterials.
Technical Principle
The core of ultra-fine silica dispersion equipment lies in utilizing mechanical force, shear force, or airflow energy to break the interactive forces between particles. For instance, air jet mills accelerate particles to supersonic speeds through high-speed airflow, causing them to fracture upon collision. Meanwhile, grinding dispersers apply a linear speed of up to 44 m/s through the micron-level gap between the rotor and stator, tearing agglomerates into nano-sized monomers. This significantly improves dispersion uniformity.
Equipment Classification
Industrial Equipment: Ultra-fine pulverizers employ airflow shear technology, with a processing capacity of up to 60,000 kg/h. Powder classification is achieved via cyclone collectors, with a fine material recovery rate exceeding 95%.
Inline Equipment: To meet continuous production demands, inline powder-liquid mixing systems eliminate residue on container walls, ensuring stable suspension of silica in solvents. This is suitable for industries sensitive to dust, such as cosmetics and pesticides.
Industry Applications: From Performance Bottlenecks to Technological Breakthroughs
In the rubber industry, the reinforcing effect of nano-silica depends on its dispersion degree. Traditional mixers struggle to break agglomerates, limiting the improvement in rubber product strength. However, with grinding dispersers, silica forms a three-dimensional network structure within the rubber matrix, increasing tensile strength by over 30%.
In coatings, the addition of nano-silica significantly enhances hardness and weather resistance. However, uneven dispersion can cause surface defects. One coatings company adopted air jet mills to control silica particle size below 50 nm, resulting in a 2-fold increase in wear resistance and a 40% improvement in gloss.
Technical Challenges and Future Trends
Although existing equipment achieves nano-level dispersion, energy consumption and equipment wear remain bottlenecks. For example, air jet mills consume 5 times more energy than traditional mixers, and ceramic grinding media are prone to wear. Future developments will focus on composite dispersion technologies (e.g., mechanical grinding + ultrasonic assistance) and intelligent control systems (real-time monitoring of particle size distribution).
From laboratory to production lines, ultra-fine silica dispersion equipment is driving nanomaterials from “proof of concept” to “large-scale application.”
