Embodiment Construction

[0035] The words "upstream" and "downstream" are understood hereinafter in the usual sense of fluid flow.

[0036] figure 1 A first example of a dosing device 10 according to the invention for injecting an infused product into a base product is shown.

[0037] Such equipment makes it possible to produce mixtures forming paints or primers.

[0038] Infusion products and base products are fluid products.

[0039] The infused product and the base product each have a viscosity between 20 and 5000 centipoise.

[0040] The dosing device 10 comprises at least one, here one, means 12 for mixing the infusion product and the base product.

[0041] The dosing device 10 also includes a computer 14 .

[0042] The mixing device 12 comprises an injection inlet 15 for supplying the injection product.

[0043] The mixing device 12 includes an injection line 16 extending from an injection inlet 15 .

[0044] The mixing device comprises a base inlet 17 for feeding the base product.

Abstract

The invention relates to a dispensing method and an associated installation. A method for dosing an injection product into a base product, in particular, for the production of a finishing and / or protective paint product, including the following steps: (a) supply of a mixing device, (b) establishment of a continuous flow of base product, (c) injection of the injection product into the continuous flow for a given time, (d) measurement of the amount of injection product injected, (e) calculation of a desired amount of base product based on the amount of injection product injected, steps (c), (d) and (e) being repeated when the amount of base product having passed since the start of step (c) is equal to the amount of base product desired, the injection product being injected into the base product only during step (c).

Description

【Technical field】 [0001] The present invention relates to a method of dosing an infusion product into a base product, in particular for the production of a finished product and / or a protective coating product. [0002] The invention also relates to a related dosing device. 【Background technique】 [0003] Currently, a continuous flow of the base product is formed, wherein an amount of the injected product is injected into the base product at regular intervals through the injection valve according to the amount of the base product that has flowed during the previous interval. [0004] This makes it possible to obtain the desired ratio between base product and infused product. [0005] However, it is difficult to control the injection amount of the injection product. [0006] On the one hand, the duration of the injection of the injected product has to be adjusted both according to the amount of base product flowing during the interval and according to the flow rate of the in...
