    冬季低温不适合环氧地坪漆施工的原因

    每年的冬季对环氧地坪漆厂家都是一个很头疼的问题,因为环氧地坪专业施工的团队都知道冬季施工是很容易出问题的,不易施工就不代表不能施工,冬季挺长的时间,不可能不开工的。冬季的来临,全国各大范围的地区气温都在下降,空气也很干燥,环氧地坪漆的施工温度一般要求在5度以上,湿度要低于85%,否则不宜施工。而低于5℃,环氧地坪涂料的地面实际效果就比较难保证。那么冬季,如何保质保量的完成工期呢?光磊环氧地坪漆厂家以多年施工经验给大家分享冬天如何施工:为什么冬季在气温低于5℃湿度大于85%,不易施工原因在这里:

    Every winter for epoxy floor paint manufacturers is a very headache, because the professional construction team of epoxy floor know that winter construction is easy to go wrong, not easy to construct does not mean that can not be constructed, winter is a long time, it is impossible not to start construction. With the advent of winter, the temperature is dropping in all regions of the country, and the air is very dry. The construction temperature of epoxy floor paint is generally required to be above 5 degrees and the humidity is below 85%, otherwise it is not suitable for construction. However, the actual effect of epoxy floor coating is difficult to guarantee when it is below 5 C. Then in winter, how to complete the project with quality and quantity? Guanglei Floor Paint Factory shares with you how to construct in winter based on years of construction experience: Why the temperature is lower than 5 C and humidity is higher than 85% in winter, the reason why it is not easy to construct is here: 1、减慢涂料反应:双组分的环氧地坪涂料施工,需要现场将甲、乙组分按比例混合,搅拌均匀,让双组分充分反应,这样才能保证地坪的效果。但如果温度低于5℃,反应将会降低或减缓,这会严重影响地坪涂料的固化性能。而固化性能的降低,将导致涂膜表面干得很慢,会增加涂膜被灰尘,杂物,或者昆虫污染的可能。

    1. Slow down the reaction of coating: In the construction of two-component floor coating, it is necessary to mix the components A and B proportionally on site, mix evenly, and let the two components react fully, so as to ensure the effect of the floor. However, if 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 film surface, which will increase the possibility of dust, debris, or insect contamination of the film.


    2、黏度成倍增长:无溶剂的自流平涂料靠流平性保证地坪的平整度。但低温下,地坪涂料的黏度会成倍增加,流平性能将降低。而不靠流平性的涂料,刮涂时会因为流动、流平性能变差,而出现镘刀痕的缺陷。

    2. Viscosity doubles: Solvent-free self-leveling coating ensures the leveling of the floor by leveling. However, at low temperatures, the viscosity of floor coatings will be doubled and the leveling performance will be reduced. However, without leveling coating, the defect of trowel marks will appear when scratching because of the poor flow and leveling performance.


    3、降低涂膜质量:由于固化反应减慢,或者完成不能固化,涂膜的强度、硬度、耐磨性都将会降低,而且会更容易出现地坪脱离等问题,严重的影响环氧地坪的使用寿命。

    3. Decrease the quality of the coating: Because the curing reaction is slowed down or the curing process can not be completed, the strength, hardness and wear resistance of the coating will be reduced, and it will be more prone to problems such as floor detachment, which seriously affects the service life of the epoxy floor.


    根据以上几个问题,我们可以这样来解决:

    Based on the above problems, we can solve them in this way:


    1、错开低温时段:环氧地坪施工时,最好在白天的上午10点至下午3点内施工,尽量错开低温时段,尽可能的减少低温的影响。

    1. Staggered low temperature period: When constructing epoxy flooring, it is better to construct it from 10:00 a.m. to 3:00 p.m. in the daytime. Staggered low temperature period is the best way to minimize the impact of low temperature.


    2、增加室温:可以把室内的温度提高,也可以在冬季进行环氧地坪漆施工,南方可以把门窗关闭,北方有条件的可以在环氧地坪漆施工前和施工的过程中供应暖气。

    2. Increase the room temperature: you can raise the indoor temperature, you can also carry out the construction of epoxy floor paint in winter, the South can close doors and windows, and the north can supply heating before and during the construction of epoxy floor paint.


    3、添加溶剂:为了解决地坪漆在低温下黏度大,缺乏流动性难搅拌,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,这样可以增加地坪漆的流动性

    3. Solvent addition: In order to solve the problem of high viscosity at low temperature and lack of fluidity and difficult stirring, solvents with a faster volatilization rate of less than 5%, such as acetone, ethyl acetate, butyl acetate, etc., can be added to increase the fluidity of floor paint.


    4、施工时一定要搅拌均匀,由于低温会使固化时间变长,所以要确定漆已经干透才能施工第二道漆。为了在低温环境同样能达到最理想的施工效果,避免漆膜弊端的出现。

    4. Must mix evenly in construction, because low temperature will make solidification time longer, so it is necessary to make sure that the paint has dried thoroughly before the construction of the second paint. In order to achieve the best construction effect in low temperature environment and avoid the appearance of drawbacks of paint film.



    还有很多方面需要我们去注意:

    There are many other aspects that need our attention:


    1、冬季施工要注意:首先紧闭门窗,可以保证室内温度,又可以避免室外风沙吹刮到未干的地面上,出现毛糙不平整的现象。

    1. Winter construction should pay attention to: first, close doors and windows to ensure indoor temperature, but also to avoid outdoor wind and sand blowing to the dry ground, rough and uneven phenomenon.


    2、施工工人施工前,关注天气预报的温度和湿度,避开在温度低于5℃湿度大于80%气温下施工;

    2. Before the construction, the construction workers should pay attention to the temperature and humidity of weather forecast and avoid the construction under the temperature below 5 C and humidity above 80%.


    3、施工到腻子或水灰,不能刮涂过厚,并且必须做到干透后彻底打磨,达到地面平整、手感光滑,否则会导致开裂、脱落现象出现。严禁一次性厚涂,导致出现发白、起泡和针孔。

    3. Construction to putty or water ash, can not scrape too thick, and must be thoroughly polished after drying, to achieve smooth ground, feel smooth, otherwise it will lead to cracking, shedding phenomenon. It is strictly forbidden to apply one-time thick coatings, resulting in whitening, foaming and pinholes.


    4、严禁采用超量使用固化剂来提高干燥速度,否则容易导致漆膜过脆引起开裂。不建议使用干速过快的固化剂。在气温较低时,有些厂家过分追求干速,而使用干速过快的固化剂,这将会导致漆膜出现开裂、阴阳面、失光等漆膜弊端。

    4. It is strictly forbidden to use excessive curing agent to improve drying speed, otherwise it is easy to cause the film to be too brittle and crack. It is not recommended to use curing agent with too fast drying speed. When the temperature is low, some manufacturers excessively pursue drying speed and use curing agent with too fast drying speed, which will lead to the defects of paint film such as cracking, yin-yang surface, loss of light and so on.


    5、冬季寒冷,生火取暖,一定要注意安全意识。冬季不宜施工,其实是因为有许多不便,并不是不能。只要我们在施工前搞清楚会遇到的问题,从各个方面进行预防,把握好尺度,这就需要专业的施工人员防患于未然。冬季施工最好请专业环氧地坪公司,他们有着专业的施工人员,不要小看环氧地坪漆施工“三分材料,七分施工”。一味的节约成本,而因小失大。

    5. When it is cold in winter, we must pay attention to safety consciousness when we make a fire for heating. Winter is not suitable for construction, in fact, because there are many inconveniences, not impossible. As long as we have a clear understanding of the problems we will encounter before construction, prevent them from all aspects and grasp the scale well, we need professional constructors to prevent them in the future. Winter construction is best to invite professional epoxy flooring company, they have professional construction personnel, do not underestimate the construction of epoxy flooring paint "three materials, seven construction". Save the cost blindly, but lose a lot because of small.
