Analysis of common problems of epoxy self-leveling
With the rapid development of industry, more and more industrial plants are required to be clean, beautiful, and dust-free and sterile. Traditional cement floors cannot meet these increasingly developed industrial environmental requirements, and are easily dirty and difficult to maintain and clean. Here we talk about the causes of the common quality problems of epoxy self-leveling floor and their solutions. First, the coating does not dry, local hardness is not enough. The performance in local quit, a few days later sticky; or some places hard, some places soft. It is difficult to handle this situation and it is difficult to remove paint. Novice construction is prone to this situation. The root cause is often caused by insufficient mixing evenly after the mixing of A and B, because the solvent-free self-leveling floor paint completely depends on the paint and the curing agent to fully react and dry. Therefore, it is necessary to mix the components of the nail varnish and stir it evenly (preferably using an electric stirrer). After stirring in a bucket, pour it into another bucket and stir it again to avoid that the attached part of the bucket wall is not stirred. After pouring it on the ground, it may form a small point. Second, the coating surface uneven color, hair This is often a paint quality issue, and some colors are particularly prone to appear. The main reason is the selection and dispersion of coating pigments are unreasonable, and it is difficult to solve the construction site. In the event of such a situation, the construction shall be stopped immediately and the flooring paint manufacturer shall be required to report it and ask them to handle it. Third, coating dust and particles This is often caused by the lack of cleanliness at the scene. In general, the paint is filtered before it leaves the factory, without large impurities and particles. Therefore, in the construction of self-leveling floor top paint, not only to completely clean the dust on the ground, but also on the roof of the site, on the windowsill, equipment, construction workers shoes, construction equipment, and other debris on the dust All should be cleaned and the doors and windows must be closed to prevent the wind from blowing in outdoor dust. Fourth, the surface bubble Today's self-leveling floor topcoat technology has been able to achieve a thickness of 1mm or so even without defoaming nail roller will not be a bubble, but if thicker, then the use of nail roller defoaming process is still necessary. Because the liquid paint inevitably mixes into the air to cause bubbles to form during stirring or coating process, the thicker the coating, the less easily the bubbles escape and break, and if the coating fails to flow, it can not escape the bubble and When the foam breaks, the pinholes formed when the bubble or the bubble is not leveled will exist. Therefore, it is suggested that it is necessary to prepare the defoaming roller and the spiked shoes during construction. In case there is steam in some places, it is better to defoam the roller as soon as possible. But be careful, as soon as possible. Because the paint is reacting and the fluidity gradually decreases with the extension of time after stirring and mixing, it is easy to run off the nail roller and affect the surface transaction. Five, knife marks The surface is marked by scars that are often unacceptable to the owner. The reasons are as follows: 1. Coating leveling is not good enough, or there is a uniform floating color phenomenon; 2. The coating is too thin and the file is too large (tooth too deep); 3. Workers are not cooking, uneven coating. Sixth, the surface roughness is too poor This is often caused by insufficient work on the floor leveling before the paint is applied. Although the self-leveling floor paint has a certain self-leveling effect, this effect is limited by the thickness of the surface layer. It is impossible to use too much free-flowing paint because of cost constraints. Therefore, if it is necessary to control costs and ensure that the final floor flatness is high, we must work hard to polish and seek compensation. Seven, floor coating foaming This “bubblingâ€, unlike the bubble during construction, refers to the phenomenon of blistering of the coating after the floor has been completed for a period of time. This is often caused by the fact that the groundwater level is too high and the concrete floor is not waterproofed or the substrate has a high moisture content when it is applied to the epoxy floor. Because the self-leveling epoxy floor coating has excellent sealing properties, water vapor in the base layer cannot penetrate through the coating to generate osmotic pressure. This pressure is higher than the adhesion between the coating and the substrate and it will bubble up. This phenomenon often occurs in the spring and summer when the ground temperature gradually increases. Eight, the surface is white, no light, and even sticky Epoxy self-leveling floor finishes are required for construction and curing environmental conditions. This requirement is reflected in the following two aspects: 1. The substrate surface temperature and construction environment temperature should not be lower than 5 degrees Celsius (preferably above 10 degrees Celsius). Epoxy resin and curing agent can react normally. Below this temperature, curing is too slow. 2. During the construction and curing of self-leveling paint, the relative humidity of the environment should not be higher than 80%. When the humidity is too high, the water vapor will condense on the unfinished paint surface and react with the amine curing agent, causing the surface gloss of the coating film to decrease and fogging. White (white), sticky, oil, low hardness and other defects. Xiao Bian concludes: The above has introduced the analysis of common problems of epoxy self-leveling and hopes to help everyone.
