The invention concerns a method for production and spray-application of a multicomponent paint in an installation comprising a main line (3) at one end of which emerges a conduit (4) supplying a base colour shade, and at the other end of which is mounted a sprayer (14), said line comprising a flow rate regulating device (10) controlling the flow of the product dispensed by the sprayer. Said method consists in: inputting at least a hardener in the main line from a secondary line; measuring in the main line the flow rate of the mixture comprising a base colour shade and hardeners; then, on the basis of the base colour shade/hardener volumetric ratio of the specific mixture, regulating the flow rate of each of the hardeners so as to obtain the predetermined volumetric ratio.
A method of producing, and of applying by spraying, a multicomponent paint in an installation comprising a main line (3) into one end of which runs at least one line (4) for supplying a base color and mounted on the other end of which is a sprayer (14), this line including a flow regulating device (10) that determines the rate of flow of the product delivered by the sprayer, characterized in that it consists in:
An installation for producing, and for applying by spraying, a multicomponent paint consisting of a base color and at least one hardener, comprising a main line (3) into one end of which runs, via a valve (5), at least one line (4) for supplying a base color and mounted on the other end of which is a sprayer (14), this line (3) including a flow regulating device (10) that determines the rate of flow of the product delivered by the sprayer, characterized in that at least one secondary line (16) runs into this main line (3), at least one line (20) for supplying a hardener running, via a valve (19), into the end of said secondary line (16), this line (16) being equipped with a motor-pump assembly (23, 24) intended to transfer the hardener into the main line (3), the latter having, downstream of the point where it joins the secondary line and upstream of the pressure regulator (10), a flowmeter (8) which, by continuously measuring the flow rate of the base color/hardeners mixture, controls the motor-pump assembly by means of a variable-frequency supply so that the flow rate of the hardener sent by the pump (23) into the main line (3) makes it possible to respect a predetermined base color/hardeners volume ratio.
