Engineered with precise pore distribution and optimized particle sizes for extreme performance under demanding industrial environments.
Establishing advanced industry baselines for dynamic moisture control, catalytic purification, and specialized molecular structures since 1994.
Shanghai Jiuzhou Chemicals Co., Ltd. (JOOZEO) is strategically headquartered in Shanghai, China's premier global industrial and economic development hub. Guided by the core tenets of absolute quality control and consistent structural innovation, Jiuzhou has established a global footprint as an authoritative developer and manufacturer of high-purity micronized zeolite powders and inorganic adsorbents.
Our sophisticated product line features micro-crystalline molecular sieve powders, active pore desiccants, activated alumina, synthetic metal catalyst supports, specialized sodium silicates, and custom-crystallized 4A/13X zeolites. We deliver state-of-the-art adsorption solutions tailored to mitigate moisture trace contamination in polymers, coatings, sealants, and gas systems.
To assure absolute quality reliability, all manufacturing processes run under rigorous controls verified by ISO9001:2008, TUV, and SGS international certifications. Supported by a world-class central laboratory and deep chemical analysis apparatuses, JOOZEO bridges the gap between raw inorganic mineral synthesis and critical micro-dispersion requirements demanded by global aerospace, automotive, energy, and environmental enterprises.
Absolute structural consistency guaranteed by raw-material silicate integration and in-line X-ray Diffraction (XRD) phase analysis.
Pioneering sub-micron surface modifications and specialized organic silane treatments for hydrophobic PU resins and functional masterbatches.
A comprehensive assessment of structural frameworks, micro-dispersion kinetics, and synthetic chemical engineering.
Micronized synthetic zeolite powders are crystalline sodium aluminosilicates featuring three-dimensional pore networks. Depending on the design (3A, 4A, 5A, or 13X), these structures offer precise pore openings (3 Å to 10 Å). By leveraging electrostatic field gradients within these pores, they selectively adsorb molecules based on size and polarity, targeting water molecules (kinetic diameter ~2.65 Å) while excluding bulk resins or solvents.
Traditional molecular sieves exist in spherical beads or extruded pellets. For integration into polymers, coatings, and sealants, the crystal must undergo ultra-fine micronization. JOOZEO targets a strict particle size distribution (PSD) where D50 is maintained below 4 microns and D90 under 10 microns. This narrow PSD prevents aggregation, mitigates surface defects in final films, and optimizes viscosity properties in liquid resins.
Unactivated zeolites carry highly saturated crystalline water inside their aluminosilicate cages. To make them active moisture scavengers, the raw powder undergoes controlled rotary calcination above 550°C. This intensive calcination process reduces the residual water content to less than 1.0% by weight, optimizing the powder's capacity to scavenge moisture down to parts-per-million (ppm) levels upon introduction to target compounds.
Deploying specialized micro-crystalline adsorbents across critical global manufacturing and high-tech sectors.
In two-component polyurethane coatings, sealants, and structural adhesives, trace moisture reacts with isocyanate groups to form carbon dioxide (CO2) gas, leading to pinholes, structural micro-foaming, and compromised adhesion. JOOZEO's micronized zeolite powder functions as an in-situ moisture scavenger, binding trace water fast enough to outpace the isocyanate-water reaction pathway, ensuring bubble-free curing.
High-performance corrosion protection coatings containing zinc dust or metallic pigments are highly sensitive to moisture. Water contamination triggers gas formation within storage drums, causing bulging, dangerous pressurization, and pigment oxidation. Incorporating 1.5% to 3.0% active micronized zeolites eliminates this moisture, securing product shelf-life and rheological stability.
For insulating glass units used in modern architectural glazing, maintaining a condensation-free cavity is critical. Ultrafine zeolites dispersed inside the primary polysulfide or polyurethane sealants continuously capture moisture permeating the perimeter seals. Their high physical stability prevents fogging or chemical leaching over decades of exposure to cycling temperatures.
Ensuring operational continuity and dynamic scale-up through vertically integrated raw material pipelines and strategic port locations.
Managing global distribution requires secure supply chains. JOOZEO optimizes shipping routes, transit safety, and volume consistency by separating its manufacturing operations into two main facilities: the Shanghai Factory and the Wuxi Factory.
Our raw material supply chain benefits from backward integration. We manufacture our own liquid sodium silicate precursors directly, insulating our chemical lines from pricing volatility and purity variations in the merchant silicate market. Fully automated calcination rotary kilns paired with closed-loop jet mills ensure that every ton of output meets target specifications without contamination.
With our prime location near the Port of Shanghai, we provide regular shipping options to key hubs in the Americas, Europe, the Middle East, and Asia. Safe-handling barrier packaging (aluminum-barrier vacuum sacks with heat-sealed closures) preserves active adsorption capacities from our production lines to your mixing tanks.
Focuses on advanced synthesis, crystal shape modification, and high-purity testing procedures.
Specializes in high-volume calcination, micronized milling, and large-scale bulk chemical packaging.
Pioneering national industrial standards to ensure consistent validation metrics across the chemical adsorption sector.
JOOZEO does not simply follow industry specifications—we actively define them. Our research engineers collaborate with state research agencies and trade groups to write key industrial standards for dryers, aluminas, and adsorbents.
