Floor grinder manufacturers said that floor blisters mostly occur on the first floor or basement, and sometimes above the second floor. Floor blisters are generally found shortly after construction, and some epoxy floors paved in the morning have blisters in the afternoon. Blisters from small to large, continuous development, development to a certain extent after the stop.
The higher the temperature, blisters are more likely to occur and develop faster. Blisters vary in shape and size. Some blisters have a diameter of more than 1m and a height of 20~50mm. There is no obvious relationship between the generation of blisters and the construction area. Some of them are serious, some are lighter and some are intact in the same area. The same group operation, the same material construction of the epoxy floor, some blisters, some intact, indicating that blisters are caused by a variety of factors. The cause of blisters is a problem that everyone is concerned about. When the blisters are cut open, it is found that the blisters contain water or yellow liquid. The epoxy ground layer is separated from the base layer, and the cementing material stuck on the base layer is pulled into a peak nest. According to the explanation of "physics", in a closed container containing liquid, the liquid evaporates to form the temperature and pressure relationship of three curves of saturation state.
Floor grinding machine manufacturers analysis, which no blisters part of the epoxy layer and the ground part of the bond is not strong, careful observation of the contact part, will also find that there is no curing part, because the epoxy moisture can not cure; so where does the water come from? There are mainly the following sources of water: 1 base, such as cement mortar leveling layer, the maximum water content of about 12%, the maximum water content of the base is greater than the leveling layer. 2. The dehydration of other ingredients in epoxy is endless. 3. Epoxy and base construction when combined with the poor leaving voids and epoxy itself chemical activity, not fully cured or encountered moisture is not fully cured residue or gas. 4. Moist gas permeated underground at the base level.
