    厂家对环氧地坪漆固化时间及混合使用寿命解读

    解决环氧地坪漆缺陷对策:A、 施工温度控制在15~25°C之间;不要随意在现场加溶剂。 B、 混合好的环氧地坪材料要及时流展在施工基面上,不要一直存放在混合的容器里,涂料接触混凝土被冷却,反应热能及时散发,可以使固化时间变长,混合使用寿命增加;另外,混合使用寿命的关键在于树脂和所选择的固化剂的配比用量,所以要严格根据环境温度的变化来确定固化剂的种类和用量。

    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.

    环氧地坪施工后常有出现固化时间控制不好,混合后的地坪涂料使用时间变短等现象。现在就针对这两种现象分析下原因和对策。

    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.

    缺陷状况及原因:

    Defects and reasons:

    1、固化过慢。固化过慢就是环氧树脂材料在特别低的温度下(10°C)固化反应变慢。5°C一下是绝对禁止施工。这个现象和黏度有着很大的关系,温度越低,黏度就会越高,那么就会比较难施工。固化时间过长会造成涂膜沾染灰尘、沙粒等赃物,甚至会拖慢工期。还有一点就是在施工现场加溶剂也会造成固化过慢,因为溶剂的挥发会带走一部分热量而冷却涂膜。

    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、使用寿命缩短。配制好的地坪涂料如果一直放置在容器里的话,会蓄积反应热,导致固化变快,可是却影响了地坪的使用寿命。一般施工环境温度越高,通风差,都会导致使用时间变短。

    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.
