    低温下环氧地坪的施工减慢涂料反应解决方法

    环氧地坪最佳的施工环境是怎么样的呢?一般来说,很多人都认为无性系环氧地坪不管在什么时候施工都是最好的,但是据小编的了解,无锡环氧地坪涂料的最佳施工环境是湿度小于75%,温度10-35℃,一般来说5℃以上也可以施工,低于5℃,无锡环氧地坪涂料的实际效果就比较难保证。如果在低温的环境下,无锡环氧地坪涂料的施工为什么就很难了呢?

    What is the best construction environment for epoxy floor? Generally speaking, many people think that clone epoxy floor coatings are the best construction at any time, but according to Xiaobian's understanding, the best construction environment of Wuxi epoxy floor coatings is humidity less than 75%, temperature 10-35 C. Generally speaking, it can be constructed above 5 C, below 5 C. The actual effect of Wuxi epoxy floor coatings is difficult to guarantee. If in low temperature environment, why is the construction of Wuxi epoxy floor coating difficult? 环氧环氧地坪原因如下:

    The reasons for epoxy flooring are as follows:

    1、减慢涂料反应。

    1. Slow down the reaction of paint.

    温度低于5℃,反应将会降低或者减缓,这会严重影响环氧地坪涂料的固化性能。而固化性能的降低,将导致涂膜表层干的很慢,会增加涂膜被灰尘,杂物,或者昆虫污染的可能。

    When the temperature is lower than 5 C, the reaction will be reduced or slowed down, which will seriously affect the curing performance of floor coatings. The decrease of curing performance will result in the slow drying of the coating surface, which will increase the possibility of dust, debris, or insect contamination.

    2、黏度成倍增长。

    2. Viscosity doubles.

    无溶剂的自流平涂料无需刮涂,靠流平性保证地坪的平整度。但是低温下,地坪涂料的黏度会成倍增加,流平性能降低。而不靠流平性的涂料,刮涂时会因为流动,流平性能变差,出现镘刀痕等缺陷。

    Solvent-free self-leveling coating does not need scratching, and the leveling property ensures the leveling of the floor. However, at low temperature, the viscosity of the floor coating will be doubled and the leveling performance will be reduced. However, without leveling coating, scraping will be due to flow, poor leveling performance, such as trowel marks and other defects.

    3、降低涂膜质量。

    3. Reduce the quality of the film.

    由于固化反应慢,或者完全不能固化,涂膜的强度、硬度、耐磨性能都会降低,而且容易出现地坪脱离问题,严重影响无锡环氧地坪的寿命。

    The strength, hardness and wear resistance of the coatings will be reduced due to slow curing reaction or no curing at all, and the problem of floor detachment is easy to occur, which seriously affects the life of Wuxi epoxy floor.

    解决办法:

    Terms of settlement:

    冬季低温环境下,涂料固化速度变慢,状态变粘稠,施工难度加大,涂料本身质量下降。但尽管冬季无锡环氧地坪漆施工难度大,质量难保证,但如果工程确实需要再冬季或低温环境下施工,则可参考如下的办法。

    Under the low temperature environment in winter, the curing speed of coatings becomes slower, the state becomes viscous, the construction difficulty increases, and the quality of coatings decreases. However, although the construction of Wuxi epoxy floor paint in winter is difficult and the quality is difficult to guarantee, if the project really needs to be constructed in winter or in low temperature environment, the following methods can be referred to.

    1、隔开低温时段

    1. Isolation of Low Temperature Period

    无锡环氧地坪漆施工时,尽量隔开低温时段,上午10点后再开始施工,下午3点停止施工,减少低温的影响。

    During the construction of Wuxi epoxy floor paint, try to isolate the low temperature period, start construction after 10 a.m. and stop construction at 3 p.m. to reduce the impact of low temperature.

    2、增加室温

    2. Increase room temperature

    冬季施工建议在室内进行,室内温度较高增加室内温度,把温度提高到5度以上,这样也可以在冬季施工。北方很多厂房有供暖气,可在施工前和施工中开放暖气供应。

    Winter construction is recommended indoors. Higher indoor temperature increases the indoor temperature and raises the temperature to more than 5 degrees. This can also be done in winter. Many factories in North China have heating, which can be opened before and during construction.

    3、添加溶剂

    3. Adding Solvents

    可适量添加挥发速率较快的溶剂,可添加小于5%的挥发速率较快的溶剂,如丙酮、醋酸乙酯、醋酸丁酯等。这样可以解决地坪漆在低温下黏度大,缺乏流平性的问题。这样可以解决地坪漆在低温下黏度大,缺乏流平性的问题。

    Solvents with faster volatilization rate can be added in appropriate amount. Solvents with faster volatilization rate less than 5% can be added, such as acetone, ethyl acetate, butyl acetate, etc. This can solve the problem of high viscosity and lack of leveling of floor paint at low temperature. This can solve the problem of high viscosity and lack of leveling of floor paint at low temperature.

    4、涂料加热

    4. Coating heating

    可将地坪涂料储存在温暖的环境中或用热水、蒸气加热涂料(可能造成涂料质量的下降)。当温热涂料时,除非采用特别的涂料加热设备,其温度不要超过38℃。涂料闪点低于38℃时,加热温度不得超过其闪点注意不要让蒸汽或热水进入涂料内。

    Floor coatings can be stored in a warm environment or heated with hot water and steam (which may result in a decline in paint quality). When a thermothermal coating is applied, the temperature shall not exceed 38 C unless a special coating heating device is used. When the flash point of the coating is below 38 C, the heating temperature should not exceed its flash point. Be careful not to let steam or hot water enter the coating.
