Pencil Leads TRIZ Cases
- Oil-based inkjet ink
See how branched fatty acid ester solvents with 12-23 carbons use steric hindrance to prevent p
- Hidden Fluorescent Vehicle Marking for Theft-Resistant Identification
A fluorescent code migrates into vehicle paint, stays hard to detect or remove, and remains readable even after repainting.
- Porous Graphite Pencil Lead Impregnation for Dense, Fixable Lines
Impregnating porous graphite lead with selected esters and resins boosts line density and fixability while reducing hand smearing.
- Polymer Pencil Lead Composition for Strength and Smooth Color Laydown
Lamellar mineral fillers in extruded polymer pencil leads improve flexural strength, shock resistance, smooth writing, and color vividness.
- Non-Baked Pencil Lead Composition for Moisture-Resistant Tip Strength
A crosslinked resin and polycaprolactone composition strengthens non-baked pencil leads, resists moisture loss, and improves line density.
- Low-Temperature Geopolymer Pencil Lead for Tip Strength
Specific XRD clay and alkali activation enable pencil lead to keep pointed-tip strength, resist moisture, and fire below 500°C.
- PLA-PBS Pencil Body Composition for Sharpenable Mechanical Strength
Combining PLA, PBS, wood fibers, and a maleic-anhydride compatibilizer gives pencil bodies the strength and flexibility needed for sharpening.
