Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current micronutrient-coated fertilizers face issues with temporary adhesion, caking, and environmental unfriendliness due to water-soluble bonding agents, leading to inefficient micronutrient delivery and potential soil microbial damage.
Innovation Solution
A micronized composition comprising water-soluble micronutrients, a clay binder, and a dehydrating agent, micronized to an average particle size smaller than 50 μm, using a high-shear high-impact mill and biodegradable bonding agents like lignosulphonate, ensuring stable adhesion and environmental sustainability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If water-soluble bonding agents are used to coat micronutrients onto fertilizer granules, then adhesion is achieved initially, but the adhesion is temporary and micronutrients detach within a short time
Solution Approach 1:
The patent changes the chemical composition parameters of the bonding agent by replacing conventional water-soluble adhesives with a water-insoluble bonding agent containing carboxylic acid groups. This parameter change transforms the bonding mechanism from water-dependent adhesion to chemical bonding via carboxylic acid groups, thereby achieving stable long-term adhesion of micronutrients to fertilizer granules without detachment issues
Solution Approach 2:
The patent creates a composite bonding system combining water-insoluble bonding agent with carboxylic acid functional groups. This composite material approach integrates the water-insolubility property for adhesion stability with the carboxylic acid groups for chemical bonding capability, resolving the contradiction between initial adhesion and long-term retention
2Reliability
If bonding agents containing water are used to coat micronutrients, then adhesion is achieved, but chemical reactions occur causing caking, dissolution of fertilizer granules and degradation of the overall product
Solution Approach 1:
The patent changes the water content parameter of the bonding agent from water-soluble to water-insoluble formulation. This parameter change eliminates the water that causes harmful chemical reactions, caking, and fertilizer granule dissolution, while maintaining adhesion stability through the water-insoluble bonding agent with carboxylic acid groups
Solution Approach 2:
The patent converts the potential harm of water in bonding agents by replacing it with a water-insoluble alternative. The carboxylic acid groups in the water-insoluble bonding agent provide beneficial chemical bonding capabilities without the harmful effects of water-induced caking and dissolution reactions
3Reliability
If bonding agents containing bunker oils or industrial waste products are used, then adhesion is achieved, but the products are not environmentally friendly and may destroy microbial life in the soil
Solution Approach 1:
The patent replaces conventional bonding agents with a biodegradable starch-based bonding agent containing carboxylic acid groups. This substitution uses an environmentally benign, biodegradable material that maintains adhesion stability while eliminating harm to soil microbial life and the environment
Solution Approach 2:
The patent changes the chemical composition parameter of the bonding agent from petroleum-based bunker oils to biodegradable starch-based materials with carboxylic acid groups. This parameter change achieves adhesion stability through chemical bonding while eliminating environmental toxicity and microbial damage
