Car Paint Quantity: Estimating Varnish & Waste for a Fiat Punto in a Spray Booth

It's hard for me to get such data, but when it comes out more or less - let's say we have the whole car already phosphated and we start painting with a gun in the spray booth - how much varnish will come out of it and how much waste will be there. Such estimated information cannot be obtained, but I need it for my diploma thesis.

As an example of a car, let's say Fiat Punto. Maybe someone works in the paint shop? Maybe someone has a car paint container with them and the performance is given there?

Hello
It's hard to say how much paint goes on the car. It depends on many factors. What paint, how many layers, how complicated is the car structure, will it be painted inside (engine compartment, etc.) and maybe who is also painting. How much paint goes into the air depends on the method of painting, where to paint and who is painting.

From what I read briefly, this car has about 19 m2 - parts of the exterior of the Nissan Primera. The engine is probably cataphoretically covering. And for such a medium-sized car, 5 liters are available. Only how much of it drips off as SLUD and how much will evaporate. An average for the varnish is enough and let's say someone knows about it.

Let's say we have one backing layer and 3 outer layers. I do not know what is the matter with the inner part of the car body, how many layers are there. Perhaps I am interested in the data on how much paint sludge in the spray booth per car is. Let's say a paint shop of 20 cars and how many barrels of sludge they produce ...

on a medium size car such as Ibiza mk1 goes from 1L to about 4L - it all depends on:
1. the skills of the painter
2. whether we change the color of the car
3rd varnish manufacturer
4. the color of the paintwork

so as you can see the forks are huge and it's hard to say exactly how much of it will come! some varnishes / colors cover the other better, the other one ... on average, about 1/3 of the total amount is a solvent that evaporates, a certain amount goes into the air as waste / blow, etc., etc ... and it is impossible to accurately determine how much we the paint will come off, therefore there is no ntt data!

At work, you can enter the amount, e.g. 3L, if they have any questions where this info comes from, answer that yesterday you painted such a car, not a questionable argument. But seriously, check this forum http://www.farby.brcs.pl/phorum/list.php?f=1 Regards

I had an apprenticeship in a steel coating factory and so far know the exact proportions of the ingredients inside. It would be useful to analyze how many guns are blown out in addition to the paint of solvents and how many do not hit the car because the sum sumarum with more cars appears sludge.

Because if you count that 1 liter is enough for 20m2 and covers a 20um layer, we have a layer with a volume of 0.4 liter = 20um x 20m2 only 0.6 liters evaporated somewhere. I understand that there is a contraction, I will evaporate a little on the way, some will stay on the gun. But how much paint will not go under the car, to the sides of the cabin, to the filter, to the water vacuum, etc. in combat conditions.

The work is about varnish sludge. Because recently they put one in jail for keeping such buckets in a bricked-up room. Well, looking at their properties, they can be used to make everything, burn it, make damping materials for the car ...

It all depends on the effectiveness of the gun, HP high-pressure guns have, from what I remember, about 50% efficiency, i.e. only half of the paint goes to the painted surface, while (HV) LP (low pressure) have an efficiency of about 70% (but for painting with such guns you need an efficient hand) it all depends on the manufacturer of the gun.

Hello. As my previous speaker wrote, the dust goes from 30 to 50% depending on the gun. To paint Punto in acrylic, I would buy 1.5 or 2 liters of paint (if I mixed it in accordance with the 2: 1: 1 ratio, I would get 3 or 4 liters) depending on whether the center would be painted. Of course, the amount of paint also depends on the color, because not all of them cover the same.

the ratio of the varnish is 2: 1 and max. 10% solvent for acrylic varnishes, for base varnishes 2: 1 and 1: 1 depending on the manufacturer, we do not dilute water-based varnishes, they are immediately ready for use and are still more efficient than the others. As for the efficiency, there are differences depending on the gun and the ability of the painter, one needs 1 liter, the other 2 liters for the same car, the painting surface also has a big impact, the larger the surfaces, the greater the efficiency, with small surfaces most of the paint goes into the air. according to manufacturer, how much paint is needed for a meter, for example, I can give something on Monday

He's not in too much of a rush. It is about estimates that I already need to know very much. As far as I know, 1 liter per 20m ^ 2.

It is simply about the source according to which it would be possible to estimate how much varnish waste is generated in Poland, some respect

Try to call or write to the sales representative of one of the manufacturers, he may give you an estimate of how many varnishes they sell each year. I think that on this basis it will be easiest to estimate the amount of waste, and maybe they have some data.

PS The proportions and the estimated quantity per 1 m2 are given on the websites of some producers. Regards

You would have to know all the manufacturers. And the producers often do not provide anything for reasons of industrial secrecy.
