The reasons for the roughness of polyurethane epoxy floor paint are as follows: 1. The construction environment and the drying process of the epoxy floor paint film are not clean and dusty, which makes the dust fall on the film which is still in the leveling stage, and eventually causes the dust to adhere to the floor paint film and makes the film rough.
2. The epoxy floor paint is not filtered before painting, and is mixed with mechanical impurities. These mechanical impurities are coated on the coatings together with the coatings. When the coatings are dried, the mechanical impurities are highlighted on the floor paint coatings, which eventually leads to the appearance of rough coatings.
3. Because the polyurethane epoxy floor paint is a two-component or multi-component coating, and belongs to chemical curing coating, when the paint is mixed with curing agent, the paint begins to play a chemical role, and the viscosity of the floor paint gradually increases, and begins to gelatinize after a specific time, and finally solidifies directly into a film. When the paint starts to gel and continues to be constructed, the paint film on floor paint may be rough.
Fourth, the construction site temperature is too high, the diluent volatilizes too fast, the epoxy floor paint coated on the coating has no leveling time has begun to solidify, so there will be rough phenomenon.
How to solve the problem of roughness?
Do the cleaning work at the construction site and dry site, and eliminate the pollution of the dust on the epoxy floor paint film. Before coating construction, according to the requirements of product specifications, after mixing the floor paint (according to the proportion of each component, and then adjusting the diluent to the suitable construction viscosity), the floor paint can be filtered with 120 mesh gauze and then constructed, which can avoid the friction-promoting phenomenon caused by mechanical impurities.
Before the epoxy floor paint is painted, the amount of the paint should be calculated according to the construction time of the paint, and then the following work such as the proportion and dilution of the paint should be carried out. If there is a gelatinized floor paint, it will not be used again. Replace the spray gun that fits the caliber, adjust the air pressure and the appropriate spraying distance. Replace the slow drying high boiling point diluent.
To deal with the lower layer well, we should do a good job according to the construction requirements from the bottom layer. The middle layer should eliminate the rough phenomenon. Before the surface layer construction, we must clean the middle layer, confirm that there is no dust before construction, so that we can solve this kind of rough phenomena of epoxy floor paint.
