Paint Industry - Process DescriptionPRODUCTION OF WATER PAINTS

1. DRY PAINT WEIGHING

ENTRANCE: Tank trucks fill the tanks of dry paint.

PIGMENTS AND TALCS WEIGHING: 7 endless tanks store the components will be weighted and added to the preparation.

» Pigments dumping inside the tanks

» Pigments weighing and dosage

8

» Solid matter is weighted and then impelled up to mixture tank.» The impulsing is realized by pressurizing the air from the corresponding compressors.» The material is thrown through a single pipe up to the destination (distance of 80m approximately).

BINDERS: They are the needed resins to achieve that the paint is stuck to the treated surfaces. They must be added in the process.

After adding the pigments, talcs and resins, the water is added where the products above mentioned will be diluted in the finishing diluters.

11

In the finishing diluters the mixture are diluted and milled.There is not a separated milling.

In the finishing diluters it is possible to achieve the needed granulometry thanks to the gear wheel.

The automatized transport bands allow the cans movement up to the filling positions, where 12 automatic volumetric systems can the production.

14

One industrial robot, integrated in an operating cell, allows realizing the palletizing process automatically.


5. PALLETIZING PROCESS

» Palletizer robot

15

An industrial tintometric system allows the elaboration of mixtures in a fast and control way.

17

The great difference in this process is the milling realized with vertical and horizontal mills. In these mills, materials such as Zirconium are used to mill a first paste before arriving to the final granulating. The only use of the diluting is not enough.

» The vertical mills are driven by variable speed drives

» The horizontal mills are not driven by variable speed drives

2. PIGMENTS MILLING

Paint Industry - Process DescriptionPRODUCTION OF SOLVENT PAINTS

18

The diluters are different, since the way for obtaining the granulometry is also different (consider the previous milling stage).

For this, there is not a gear wheel. But, the diluters are also driven by variable speed drives.

The transport bands are also automatized.


4. CANNING PROCESS OF PAINT LOTS

Even if the production is smaller, the control is also realized with variable speed drive.

Equipments recommended:» SD450 Series

[ JUSTIFICATION FOR POWER ELECTRONICS EQUIPMENTS USE ][ JUSTIFICATION FOR POWER ELECTRONICS EQUIPMENTS USE ]

The variable speed drive allows reducing the speed in a control way at the ending of the weighing process, to put the required amount of pigment and guarantying the accuracy of the formula.

Keeps a correct dosage in the pigment weighing. There are pigments that can change the formula if its weight is not the required one.

22

ACTUATORS FOR PRESSURIZING IMPULSING AIR

The motors of pressurizing are controlled by Variable Speed Drives.

Equipments recommended:» SD700 Series (low frequencies)» SD450 Series

Depending on the mixture type will be impelled for each preparation, it is necessary to introduce air at more or less speed (there are some mixtures that are compressed).

Specific pigments can become very abrasive, so that its transport can generate high friction.

The variable speed drive allows regulating the ideal speed for the mixtures are not compacted.

The drive will regulate the speed, and consequently, the generated fiction

ACTUATORS FOR DILUTERS TANKS

The diluters are controlled by Variable Speed Drives.

Equipments recommended:» SD700 Series» SD450 Series

Relation rating / paint amount:» Diluter 50HP for 2.000kg.» Diluter 100HP for 5.000kg.» Diluter 270HP “1 shaft” for 15.000kg.


Depending on the preparation, the needed production and the required finished (granulometry) it is necessary to mix at more or less speed.

The variable speed drive allows controlling the equipment according to a lot of factors, such as the product amount to produce (it can realize first mixtures and then transfer to other diluters to finish).

24


ACTUATORS FOR TRANSPORT BANDS OF CANNING PROCESS

The transport bands are controlled by Variable Speed Drives.Ratings oscillate between 2 – 4 HP.

Equipments recommended:» SD700 Series (low ratings) » SD450 Series» SD250 Series (low ratings)


Allows the speed setting for more exhaustive control of the production.

The production can be programmed as needed (for example, 1 can/minute or 14 cans/minute) and the speed will be set for a correct filling.

25


ACTUATORS FOR VERTICAL MILLS

The vertical mills are controlled by Variable Speed Drives.

Equipments recommended:» SD700 Series (low ratings)» SD450 Series

This equipments mill the paint paste by using fragments of materials such us Zirconium.

With the speed increase, the temperature is also increased. This situation can generate changes in the products characteristics.

The variable speed drives allow the speed setting according to the temperature for a control of products properties.
