が挙げられる。However, in both cases, it takes a long time to remove the residual material and to clean the container when the color is changed, and there is a problem of uneven coloring. In the method of coloring using a weighing mixer in advance, the master batch weighing value becomes a trace amount unless the weighing value of the virgin material per batch is increased,
In order to ensure accuracy, weight measurement must be used, but there is a limit to micro-measurement in places with vibration such as on a molding machine. Further, if the amount per batch is large, it is inevitable that the amount of residual material will be large, and in addition, the weighing machine and the mixing machine must be large. From the viewpoint of easy cleaning, the method of directly sending to the raw material supply port of the molding machine according to the operation and processing amount of the molding machine to maintain a predetermined color density is
It is excellent because it is sent directly to the supply port of the molding machine, but it is difficult to measure the master batch minute by minute with high accuracy. This is because if the amount of resin used per shot is small, it will not reach even one grain. Also, since the liquid color system is used in a liquid state, it is necessary to replace or wash the tubes from the liquid container to the delivery port of the molding machine through the constant volume feeder, for each color, solvent, dispersion. There is a problem that the agents and the like have adverse effects such as color unevenness during molding, deterioration of physical properties, and poor appearance.
