Molecular sieve activated powder is formed by deep processing and activation of synthetic molecular sieve raw powder. It has certain dispersibility and rapid adsorption capabilities, enhances material uniformity and strength, prevents foam formation, and extends product lifespan. When selecting an activated powder, multiple parameters need to be considered, among which fineness, static water adsorption capacity, and pH value are the most commonly used indicators.
1. Fineness
Fineness refers to the particle diameter of molecular sieve activated powder and is a critical parameter that directly affects product performance and quality. The finer the powder, the better its adsorption performance, catalytic activity, flowability, and solubility. A lower numerical value indicates finer particles and higher product quality.
JOOZEO’s molecular sieve activated powder has a fineness of 2-6 microns, offering advantages such as fast defoaming speed, high water absorption, rapid adsorption rate, excellent dispersibility, and anti-settling properties.
2. Static Water Adsorption Capacity
Static water adsorption capacity is a key indicator of activated powder. A higher value indicates stronger adsorption capability, a more developed internal pore structure, and higher activity.
JOOZEO’s molecular sieve activated powder exhibits high adsorption capacity, with the 13X series achieving a static water adsorption rate of over 28%. It provides fast defoaming, high water absorption, high adsorption rate, good dispersibility, and anti-settling properties.
In applications such as coatings, adhesives, and sealants, a higher static water adsorption capacity helps effectively reduce moisture content, improving product uniformity, strength, and service life.
Moreover, since activated powders with high static water adsorption require lower dosage in practical applications, they help reduce production costs.
3. pH Value
The pH value of activated powder indicates its acidity or alkalinity, which affects its stability and selective adsorption capabilities for specific substances.
For example, activated powders with lower pH values are more suitable for polyurethane systems, as they help stabilize raw material synthesis reactions.
In coatings and sealant applications, an activated powder with a moderate pH value disperses better in the system, enhancing product stability and longevity.
JOOZEO’s molecular sieve activated powder typically has a pH value of ≥9, ensuring better adsorption performance and stability, and it can be optimized and adjusted according to specific application needs.
Main Application Areas of Molecular Sieve Activated Powder
1. Used as an amorphous desiccant in spacer bars for insulating glass.
2. Applied in polyurethane-based products (coatings, adhesives, and sealants) to prevent foam formation and extend product lifespan.
3. Used as an additive or filler in coatings, paints, resins, and certain adhesives to reduce moisture, eliminate bubbles, and enhance material uniformity and strength.
4. Used as a selective adsorbent, added to specific polymers or coatings to adsorb gases like CO₂ and H₂S generated during production.
