Commercially pure polyester raw material sources A, B, 520, 520, 41 41 cab tgic cattle pond 1 1 benzoin 2 2 tr33 Jiang Xitian light 20 as 20-80 highlights the Ca 1 1 carbon black 0.2 0.2 334.8 414.8 red curing 200 ℃ / min mitsubishi pencil hardness 10 2 H H application: A user with the AS - 20 + wax powder, pencil hardness (mitsubishi pencil) do 3 h17 features three characteristics, cost reduction function embodies reason 8 spraying powder on the rate of increase the rate of 10-15% on a powder powder has high surface polar groups and resin compatibility, high binding force function 9 spraying area of 7-8% of spraying powder weight 2.6518 features three - proportion of powder spray on the area and the rate of products AS follows: 2.65, barium sulfate, the proportion of 4.3 4.5, as a result, according to the proportion of added, spraying area of 5-15%. The unit is square meters powder dosage (g/m2) = [dry film thickness (microns) * rho (g/mL) * 1000] volume solids volume solids * 10 powder coating is 100, so the dosage and powder coating is directly proportional to the density of computing: a formula of organic components 70 powder, density of 1.1 g/mL, inorganic filler 30, calculating the density of powder coating barium sulfate for packing powder density of 1.5 g/mL; As-20 powder coating density of 1.4g/mL60 m dry film per square meter dosage: barium sulfate 90as-20 84 powder per square meter (weight) 6.
