Solutions to the defects of floor paint: A, the construction temperature should be controlled between 15 ~ 25 degrees C; do not add solvents in the field at will. B. Mixed floor materials should be timely spread on the construction base, not always stored in mixed containers, paint contact with concrete is cooled, reaction heat can be released in time, can make the curing time longer, mixing service life increased; in addition, the key to mixing service life is resin and selected curing agent. The dosage and dosage of curing agents should be determined strictly according to the change of environmental temperature.
The curing time of epoxy floors is not well controlled and the use time of mixed floor coatings is shortened after construction. Now we will analyze the reasons and Countermeasures for these two phenomena.
Defects and reasons:
1, curing too slowly. Curing too slowly is the slow curing reaction of epoxy resin at particularly low temperature (10 degree C). 5 degrees C is absolutely prohibited construction. This phenomenon has a great relationship with viscosity, the lower the temperature, the higher the viscosity, then it will be more difficult to construct. Too long curing time can cause dust, sand and other stolen goods, even slow down the construction period. Adding solvents to the construction site can also cause slow solidification, because the volatilization of solvents will take away part of the heat and cool the film.
2, shorten the service life. Prepared floor coatings, if kept in containers, will accumulate reaction heat, resulting in faster solidification, but it affects the life of the floor. The higher the ambient temperature is, the worse the ventilation time will be.
