The environment is getting worse and worse. Environmental pollution has always been an eternal topic. Environmental pollution includes water pollution, environmental pollution, air pollution, volatilization of oily floor paint into air pollution, paint: banana water, water as a diluent, containing a large number of benzene, xylene and other harmful substances. It has strong pungent odour, which is unbearable and harmful to human body. Contains a large number of harmful substances, harmful to human health, generally 1-2 months after use, strong irritant odor volatilization to the basic tasteless, but a large number of harmful gases will still slow release volatilization for 10-15 years.
Consumers have realized that oily floor paint is out of date, water-based epoxy floor paint is sustainable development, water-based epoxy floor paint only as a diluent, harmless to human health does not contain harmful substances, will not volatilize into the air, so there will be no flaws such as yellowing, more durable as new and so on. So how do consumers buy real waterborne epoxy floor paint when they choose to buy, here are some suggestions for you.
First of all, we should see the test report. The product must comply with the requirements of the national standard for synthetic resin emulsion paint and the standard for harmful substances in interior coatings for interior decoration and finishing materials. The testing organization must be approved by the State Technical Supervision Bureau and has the CMA detection mark.
Secondly, see the paint particles, take a small amount of paint into clear water, gently agitate, observe whether the water is still clear, paint particles are uniform in size, whether the water is relatively independent, no adhesion phenomenon. Inferior paint will be turbid immediately after stirring, and the size of particles will be uneven. Good water-based paint should not drop powder, has a certain degree of washability, can be used clean water scrubbing, after wiping wet cloth, the color is still bright as new.
Waterborne epoxy floor
Let's take a look at waterborne epoxy floor paint.
As the name implies, water-based floor is water as a dispersion medium, can be constructed in a humid environment. Water-borne floor is a relatively environmentally friendly floor now, after the construction of its smell is also relatively small, in the event of some fires, the ground is not easy to fire, high safety factor. More importantly, it has a strong permeability, the surface will not blister, gloss is also very soft. Epoxy resin coatings are widely used in industrial floors because of their high hardness, good wear resistance, strong adhesion and excellent chemical resistance.
But waterborne floor paint also has some disadvantages: high surface cleanliness requirements. Water-borne epoxy floor coatings require high cleanliness of the ground, because the surface tension of water is large, dirt easily causes shrinkage of the film; not suitable for low-temperature construction. Because of waterborne coatings, low temperature will affect the performance of coatings. The oil epoxy floor coating can be constructed only if it is above 5 C. The dispersion stability of strong mechanical forces is poor. Corrosiveness. The corrosion resistance of the coating equipment is high, and the anticorrosive lining or stainless steel coating tools are needed. The cost of the equipment is high. The cost is high. The material cost is higher than that of the different epoxy floor coatings, and the construction cost of the industrial area is too large.
Everything has its advantages and disadvantages, weighing the two, from the level of water-based epoxy floor paint, its advantages are definitely greater than the disadvantages.
At present, the industrial floor coatings in China mainly use solvent-based epoxy floor coatings and solvent-free epoxy floor coatings. Solvent-based epoxy floor coatings contain a large number of volatile organic solvents. Active diluents are used in solvent-free systems, which not only have certain toxicity, but also have high cost. The pollution problem of traditional solvent-based coatings has aroused great attention of the society. It is the trend of the development of floor coatings industry to substitute environmental protection products for traditional products. The epoxy floor coating instead of solvent based epoxy floor coatings is one of the research hotspots in recent 30 years. Waterborne epoxy floor coatings are non-flammable, non-toxic, tasteless, solvent-free, simple to use, belonging to environmental protection products.
