We in the masterbatch production through a series of detection, the most common detection color, dispersion, ash, melt index, resistance to temperature levels etc.. Color masterbatch and dispersion detection: 1, color masterbatch detection: carrier with the same raw materials according to the proportion (1% or 2%) added, temperature in 170 DEG C 190 DEG C, according to the different raw material by injection molding are 2.5 mm thick slices, and sample color contrast, in contrast light measurement available color tester, dark can be according to the experience in a good light conditions were compared and debugging. 2, the dispersion of the same proportion and temperature to press into the film, observe the number of pigment particles. Lu Yan Masterbatch Test of ash and melt index: 1, ash is called a certain number of color make it complete combustion ash after the proportion of. 2, the melt index is at the temperature of 190 degrees Celsius, the value of each 10 2.16KG min |
