Application of hollow glass microspheres in coatings

Radar Absorbing Coatings

Hollow glass microspheres (HGM), as a filler in composite materials, have been widely applied in fields such as coating and painting, specialty materials, and resource exploration due to their lightweight, hollow structure, thermal insulation, and chemically stable properties. In recent years, within the coatings industry, researchers have significantly addressed challenges such as poor interfacial compatibility […]

How Jet Mills Maintain a Low Grinding Temperature: A Comprehensive Technical Analysis

jet mill

Jet mills achieve precise temperature control through adiabatic expansion cooling, a thermodynamic process where compressed gas (air/N₂/CO₂) rapidly expands through nozzles, absorbing heat from the grinding chamber. As high-pressure gas accelerates to supersonic speeds and expands into the low-pressure chamber, its temperature plummets (e.g., from 25°C to -45°C at 6 bar), creating an in-situ cooling […]

What materials are best suited for grinding with a jet mill?

jet mill pulverizer

Jet mills work best on materials with certain physical properties. They help to mill the materials effectively. Here are the key factors and examples of suitable materials: Key Characteristics for Jet Milling Brittleness and Hardness Brittle Materials: They are ideal for jet milling. They fracture easily under high-speed impacts. This property enables the production of […]

How does the particle size of pharmaceutical powders affect the bioavailability of drugs?

Pharmaceutical powder

The particle size of pharmaceutical powders greatly affects drug bioavailability. This is mainly reflected in these aspects: Dissolution rate Smaller drug particles have a larger surface area. This speeds up their dissolution in body fluids. For low-solubility drugs (BCS Ⅱ/Ⅳ class), reducing the particle size can greatly increase their solubility. This speeds up the drug’s […]

how to determine material suitability for jet milling

jet mill pulverizer

Jet milling relies heavily on the physical properties of the material you process. Characteristics like brittleness and hardness directly influence the ability to achieve fine particle sizes. Moisture content also plays a critical role, as excessive moisture can hinder performance and lead to clumping. Selecting the right material ensures efficient milling and consistent product quality. […]

A brief discussion on the application and development trend of powder coatings

Kaolin used as coating

With the push for environmental protection, firms must develop eco-friendly coatings. But, eco-friendly coatings aren’t limited to water-based ones. If enterprises rush to develop water-based coatings, product homogeneity will inevitably occur. Besides water-based coatings, high-solid, solvent-free, and powder coatings are also eco-friendly. They should be the key development focus of the coatings industry. A report […]
