Technical Definition
PVA fine powder refers to micronized polyvinyl alcohol particles processed via cryogenic grinding technology, which maintains the polymer’s original chemical and physical properties while improving dissolution speed and dispersion uniformity. As a critical raw material in polymer processing, it serves as an indispensable component for enhancing product performance in adhesives, construction materials, and water-soluble packaging.
Main Categories
1. Standard Particle Size Series: Core positioning for general industrial applications, suitable for adhesives and textile sizing, with consistent particle distribution and reliable dissolution performance.
2. Custom Particle Size Series: Tailored for specialized formulation needs, suitable for dry-mix construction materials and water-soluble films, supporting particle sizes from 10 to 500 mesh.
3. Low-Foaming Modified Series: Formulated with defoaming agents, suitable for coatings and film processing, reducing foam-induced defects during production.
Design Philosophy
Our PVA fine powder technology is built on the core principles of performance preservation, customization flexibility, and reliable supply. We strictly follow full-life-cycle reliability standards to meet the harsh requirements of industrial scenarios, providing cost-effective solutions with stable performance.
Technical Principle
The core working principle of our PVA fine powder production is based on cryogenic liquid nitrogen grinding technology, which avoids thermal degradation of PVA during processing.
Implementation Logic:
1. Raw Material Preprocessing: High-purity PVA granules are screened and pre-cooled to ensure uniform processing conditions.
2. Cryogenic Grinding: Granules are ground in a liquid nitrogen environment (-196°C) to maintain polymer structure and avoid thermal damage.
3. Classification & Screening: Ground particles are classified by size using precision sieving equipment to meet specified mesh requirements.
4. Packaging & Quality Control: Finished powder is sealed and tested for particle size distribution, purity, and viscosity before delivery.
Core Architecture & Innovative Design:
1. Cryogenic Grinding Module: Equipped with 6 specialized liquid nitrogen grinders, ensuring efficient, large-scale production while preserving PVA properties.
2. Precision Particle Control Module: Advanced sieving systems maintain consistent particle size distribution, reducing batch-to-batch variation.
Comparison with Traditional Solutions:
1. Thermal Degradation Prevention: Traditional grinding uses high temperatures that alter PVA’s properties, while our cryogenic process retains original viscosity and film-forming performance.
2. Uniform Particle Distribution: Traditional methods produce uneven particles leading to poor dispersion, while our precision classification ensures consistent particle sizes for better product uniformity.
Technical Parameters & Standards
All parameters are tested in accordance with ASTM D1766 and ISO 15023 standards, with clear testing conditions and strict tolerance control. We provide full batch test reports and support third-party verification.
