Common knowledge of coating: analysis of the defects of epoxy floor coating and Solutions

Core tip: after the construction of epoxy floor coating, the curing time is often not well controlled, and the use time of the mixed floor coating becomes shorter Now we will analyze the causes and Countermeasures against these two phenomena Defect condition and reason: Shorter service life If the prepared floor coating is placed in the container all the time, the reaction heat will accumulate, which will lead to faster curing, but it will affect the service life of the floor Generally, the higher the ambient temperature and the worse the ventilation, the shorter the use time will be Curing is too slow Too slow curing means that the curing reaction of epoxy resin material changes at a very low temperature (10 ° C) Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Home of coatings: after the construction of epoxy floor coating, the curing time is often not well controlled, and the use time of mixed floor coating becomes shorter Now we will analyze the causes and Countermeasures against these two phenomena Defect condition and cause: shortened service life If the prepared floor coating is placed in the container all the time, the reaction heat will accumulate, which will lead to faster curing, but it will affect the service life of the floor Generally, the higher the ambient temperature and the worse the ventilation, the shorter the use time will be Curing is too slow Too slow curing means that the curing reaction of epoxy resin materials becomes slow at a very low temperature (10 ° C) Construction is absolutely prohibited below 5 ° C This phenomenon has a great relationship with viscosity The lower the temperature is, the higher the viscosity will be, so it will be more difficult to construct If the curing time is too long, the coating will be stained with dirt, sand and other spoils, and even the construction period will be delayed Another point is that adding solvent to the construction site will also cause slow curing, because the evaporation of solvent will take part of the heat away and cool the coating Countermeasures to solve the defects of floor paint: the construction temperature shall be controlled between 15 ~ 25 ° C; do not add solvents on site at will The mixed floor materials shall be spread on the construction base surface in time, and shall not be stored in the mixing container all the time The coating shall be cooled when contacting the concrete, and the reaction heat energy shall be distributed in time, which can make the curing time longer and the mixing service life longer; In addition, the key to the mixed service life is the proportion of resin and the selected curing agent, so the type and amount of curing agent should be determined strictly according to the change of environmental temperature Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
