Диоксид титана R231-М

R231-M is akind of rutile tio2 treated by origanic material ,which has small and even particle size, good oil dispersiblity, low absorption and good opacity. It is suggested to coating, ink, plastic and so on. 1 TiO2, %(m/m) ≥98.0 2 Color(compared with standard sample) No worse than 3 Eleminating color power(compared with standard sample) ≥ 100 4 105 °C volatile component,%(m/m) ≤ 0.3 5 After preprocess under 23+/-2C and relative humidity (50+/-5)% for 24 hours, volatile component at 105°C,%(m/m) ≤ 0.5 6 Soluble substance in water, %(m/m) ≤ 0.6 7 PH value of suspended substance in water 8.0-8.5 8 Oil absorption, (g/100g) ≤ 22 9 45µm residue on sieve, %(m/m) ≤ 0.05 10 Resistance value of water liquid extract, Ωm ≥ 20 11 Content of Rutile(%) ≥ 98 12 Package:25KG paper bag with pallets
