Water bag water colorful paint construction all kinds of headache problems how to solve?

China Paint Online News Information
Water-wrapped colorful paint refers to water as a solvent or as a dispersed medium, a coating can get color patterns of the paint, is not only in line with environmental protection and energy-saving requirements, but also give people an elegant spectacular, magnificent and colorful sense, novel and has potential, in line with the future direction of the future development of the paint of environmentally friendly architectural coatings.
water bag water colorful paintFirst, the characteristics of water-wrapped water colorful coating
the most important attribute of water-wrapped water multicolored paint is a coating can get color patterns, because the coating is composed of insoluble two phases, one phase is dispersed phase, the other phase is continuous phase (dispersion medium), and the dispersed phase contains more than two different sizes of color particles, in the dispersion medium containing stabilizers evenly suspended, in a stable state, color generally does not disappear or conversion. When the wall is renovated and constructed, a water-based color coating can be sprayed with a special spray gun, in which the various color particles can form a variety of color effects interlesed with each other but keep their respective colors independent, similar to the natural granite effect.2, water-packed colorful paint construction is prone to problems1. Storage problems
because the water-based multi-colored coating by the dispersion phase and continuous phase two parts, between the two phases because of the relative insoluble to form water-packed colorful paint products. However, due to the difference in the proportion of the two or the system viscosity control is not right, long-term storage sometimes appears scattered phase sinking continuous phase floating phenomenon, resulting in water-based colorful paint storage after floating water layering phenomenon.。 2. Cracking problem
Although this coating has anti-cracking properties, but it is not used alone to achieve decorative effects, the wall needs to adopt a series of reasonable construction processes, such as the choice of excellent cracking-resistant flat mortar, alkali-resistant reinforced materials, alkali-resistant primers, weather-resistant intermediate paint.。 3. Construction equipment problem
Because water-based multicolored coating coating equipment has a certain degree of corrosion and adhesion, especially on iron equipment has a certain rust effect, easy to make the metal of the conveyor pipe dissolve, so that dispersed particles presumptive, coating film produces hemp point;。 4. Stability effect problem
Because of the high composition of water in water-based colorful coatings, and the strong dependence of water volatilization environment, in low humidity environment, it may dry quickly cause cracks;3. Further improve the construction process of water-based colorful coatings 1. Pay attention to the storage and transportation of coatings
For paint developers, the formulation design of water-based colorful coatings should take full account of the dispersion phase and continuous phase aqueous solution (dispersion) The proportion of the medium, the difference can not be too large, and to meet the construction of the premise to improve the viscosity of the system; Do not store the well-provisioned coating for a long time, and store the container to fit, the transport pipe shape is good, the pipe wall is defect-free.。 2. Strict construction procedures
water-based multicolored paint construction procedures include the following steps:
wall grass treatment;
putty coating;
elastic paint closed primer coating;
flexible real stone paint coating;
water-wrapped water multicolored coating;
high weather-resistant water-resistant water-resistant light coating;
stable spray effect.
construction, the wall needs a certain amount of time to maintain, to make the wall fully solidified and dry, and then completely remove loose, peeling, empty drum, powdered grass, remove dust, oil and other pollutants.
a putty coating: repair the walls with flexible water-resistant putty. The first local find flat, with putty or filler glue to fill large holes and gaps, dry after local grinding, and then full batch of putty to make the grass level. The thickness of a scraping should not exceed 0.5mm, divided into more than two construction; Each putty should be polished and trimned in time after scraping. Special attention should be paid to controlling the total thickness of flexible putty between 0.5 and 1.0mm.
elastic coating closed primer coating: with a high permeability synthetic resin emulsion made of elastic paint closed primer spray wall, in order to achieve the composite wall substrate has excellent anti-alkali closure, anti-cracking effect.
Flexible true stone paint coating: natural real stone paint with high-performance elastic silicone acrylic co-polylacemic emulsion as the base material, using pure natural precious natural stone fragments configured from the coating spray, so that the wall has good weather resistance, strong water white resistance, bendable and will not crack on the elastic substrate and so on.
Water-based colorful coating: sprayed with a special spray gun through physical changes and chemical reactions of a number of transformations, liquid water-based resin refined into gel-like water color particles, color particles independent of each other, and evenly suspended in a specific water-based emulsion, and eventually form a stable performance, particle size random non-melting water colorful paint, so that the wall produces a very artistic, colorful pattern.
High weather-resistant water-resistant hood light coating: a highly weather-resistant water-resistant hood light coating made of silicone emulsion, a single component curing at room temperature, its unique coating curing process and strong bond between chemical bonds can provide high-grade building coatings required by the extremely strong resistance to pollution, high gloss, gloss, weather resistance, water resistance and other properties.。 3. Pay attention to the artistic construction design
the above construction procedures can make the wall produce imitation marble and other realistic effects, if we carry out artistic construction design in the construction, then the decorative effect will be better.。 4. Pay attention to the effect of stability
water-wrapped water colorful paint on the construction environment conditions (temperature, humidity) requirements are more stringent, so the construction process to increase the input of temperature control and humidification equipment, with the help of electric drying and other equipment to stabilize the construction environment air humidity, temperature, so as to avoid the slow effect of the film process after construction. But at the same time, pay attention to the damage of these equipment to the wall after construction.
