solubility: gold yellow in concentrated sulfuric acid, yellow precipitation after water dilution; No change in concentrated nitric acid; Red solution in concentrated hydrochloric acid; No change in dilute sodium hydroxide solution. hue or color: bright yellow relative density: 1.27-1.49 Bulk density/(lb/gal):10.6-12.4 melting point/℃:256-257 average particle size/μm:0.22-0.39 particle shape: rod-like body specific surface area/(m2/g):11-65 pH value/(10% slurry):4.0-7.39 oil absorption/(g/100g):28-80 hiding power: translucent diffraction curve:  reflection curve:  yellow easily dispersible powder, melting point 256 ℃, soluble in ethanol, acetone, etc. Machine solvent. Good sun and heat resistance, acid resistance, poor alkaline, not affected by the role of hydrogen sulfide. |
| Use | There are 93 varieties of this kind. The particle size of Hansha yellow G is different (8-30 m2/g), and the decrease of particle size can be more transparent and the green light is strong; The coloring intensity is improved, but the light resistance and solvent resistance are reduced. The coloration strength is lower than that of benzidine yellow pigment, with a standard depth (SD) of 11%-, and C.I. Pigment Yellow 14 need only 4%-6%; Excellent light fastness Grade 5, and C.I. Pigment Yellow 14 was only grade 3. Coarse particle size goods have good hiding power, used in paint, paint printing paste, rubber and cultural and educational goods; Solvent resistance and resistance to migration is poor, heat resistance is 140 ℃, not suitable for plastic coloring. It is mainly used for coloring of high-grade light-resistant ink, iron printing ink, plastic products, rubber and cultural and educational products, and can also be used for pigment printing and viscose |
