Water-based paint : technical specifications and method of production

method of producing a water-based paint

The whole process can be divided into several stages.First - compound aqueous polymer dispersion with a pigment and a filler.The second - the resulting mixture passes dispersion (grinding of solids and liquids).Third - addition additives, which are necessary in accordance with the specifications.Fourth - the packaging of the finished material on banks.

Dispersion of ingredients is carried out in special dispersants (mills).These devices have a few cameras, and in them - a shaft with disks.It is by grinding it occurs.The resulting mixture is placed in a dissolver tank (mixer).There are well mixed, add the components according to specifications.Timing

mixing all of the ingredients depend on the properties of each component, the total volume of the mixture, as well as technical and dispersant capacity dissolver.Typically, 30 minutes enough for each operation.Thus all the work must be carried out at a temperature of +5 ° C.

preparing containers and strainers at the last stage.It is through them will be ready to pour the paint.

Advantages and disadvantages of latex paint

latex paint for walls and ceilings has a number of advantages over oil-coloring compositions.First, it dries faster .Sometimes, it is enough just a few hours, the coating has dried.Secondly, absolutely safe and harmless to humans and the environment. This means that during painting operations do not need to leave the premises immediately.

Thirdly, paint has no pungent smell, which usually lasts for several weeks after completion.Fourth, dye composition can give almost any color, adding a special pigments.To do this, even sells a special colorless composition.In DIY stores, usually offered a catalog of colors and pigments suitable for them.

Fifth, paint application process is quite simple, and all the instruments easily cleaned with plain water .You should not use any solvents.Among the shortcomings can be identified only a few: the work can only be carried out at a temperature of +5 ° C, the material is expensive.For outdoor applications you need to choose the most expensive paint, because conditions outside are significantly different from the conditions in the room.

latex paint: specifications

water-based paint for the ceiling and walls has the appropriate specifications.These include: the composition, flow rate, specific gravity, viscosity, storage conditions and shelf life.The composition of water-based paint : latex, thickener, bulking agents, antiseptic. consumption per layer of about 150-200 ml / m2.The number of layers depends on the absorbency of the substrate.

viscosity latex paint is determined according to the viscosity and should be equal to an average of 40-45 seconds (at brush application), 20-25 (using a paint sprayer).In fact, the viscosity - a measure that determines the degree of dilution with water paint.That is, a part of water added to a certain level, and then make measurement viscometer.

The proportion of latex paint is about 1.35 kg / l. Adhesion on the average 2,0mPa.Drying time is from 2 to 24 hours.It all depends on the temperature and humidity.The desired temperature of about + 20 ° C and humidity - 65%.Keep the paint should be in a dark place (away from the sun).
