Is there any way to solve the problem that plastic color toner is insoluble?

The insolubility of color toner means that the toner will not disperse. For this problem, you can add an appropriate amount of diffusion oil (generally 25kg of raw materials plus 1~2 cover diffusion oil) or diffusion powder (the proportion of diffusion powder is generally on the packaging, if the relevant manufacturers are not consulted) according to the amount of plastic before mixing, then use the mixer to stir for about 2 minutes, and then add toner to stir for 4~5 minutes after completion. (If the problem cannot be solved, you can report the situation to the toner manufacturer and ask to improve the quality of toner. )
