Solid/Semi-Solid Fertilisers TRIZ Cases
- Spherical Urea-Aldehyde Granules With Higher Crush Strength
Spheronized and extruded urea-aldehyde granules use binders to resist powdering, improve blending, and extend nutrient release.
- tBHQ Urease Inhibitor Composition for Reducing Urea Volatilization
Using tBHQ in urease inhibitor compositions helps retain nitrogen from urea by limiting ammonia volatilization while improving stability and shelf life.
- Biodegradable Fertilizer Coating Resin for Controlled Nutrient Release
A biodegradable polyester coating balances nutrient release control, coating uniformity, and lower microplastic pollution in slow-release fertilizers.
- Multilayer Polyurethane-Wax Coatings for Controlled Fertilizer Release
Multilayer polyurethane and polyolefin wax layers help prevent premature coating failure while extending controlled fertilizer release.
- Biodegradable Polymer Coatings for Controlled-Release Fertilizer Granules
Non-biodegradable fertilizer coatings create environmental concerns; PBSA-based blends enable controlled nutrient release and soil degradation within two years.
- Coated Fertilizer Granules with Interpenetrating Polymer-Wax Domains
Conditioned fertilizer granules form interpenetrating polymer and wax domains to control nutrient release rates.
- Urea-Sulphur Fertilizer Dispersion Mill Process
A dispersion mill melts and mixes urea with sulphur using a rotor-stator mechanism to produce finely dispersed particles.
- Bioplastic Material with Fertilizer for Soil Enrichment
A bioplastic material composed of carbon polymers and fertilizer enriches soil quality upon degradation.
- PLA Coating for Fertilizers via Stereochemical Solubility Control
Adjusting polylactic acid stereochemistry enables high-quality fertilizer coatings using non-chlorinated solvents.
- Photodegradable Capsule for Controlled-Release Fertilizer
A photodegradable capsule uses polyolefin and ethylene vinyl acetate copolymers to manage moisture permeation.
- Wetting Agent and Ion Exchange Nanoparticles for Granular Fertilizer Dispersion
Granular fertilizer compositions integrate wetting agents to lower water surface tension.
- Coated Granular Fertilizers Polymer Coating Mechanical Rigidity
Composite polymer coatings protect inner fertilizer granules from breakage during handling while enabling efficient nutrient delivery.
- Urea-Sulphur Fertiliser Mixing Process
A urea-sulphur fertiliser mixing process uses static and high shear dispersion mixers with ionic surfactants to achieve homogeneous blending.
- Si Clay Granules with Acid for Sugarcane Silicon Uptake
Acidified Si clay granules convert native silica to soluble silicic acid, reducing application rates and correcting silicon deficiency in sugarcane.
- Spherical Fertilizer Bodies with Thermoplastic Binder
A spherical fertilizer body uses a thermoplastic binder to join granules, reducing dust formation during transport.
- Tri-block Copolymer Coated Fertilizer Anti-floating
Olefin-based resin coating with EO-PO-EO tri-block copolymer prevents fertilizer floating while maintaining controlled release.
- Fatty Acid Triglyceride Silica Dust Binding Agent
A fatty acid triglyceride and amorphous silica combination treats fertilizer granules to reduce dust evolution.
