    高温天气环氧地坪施工易出现的问题及处理方法

    随着夏季的到来,持续的高温天气成为常态,我国大部分省市的气温都达到35℃以上,这样的高温天气对环氧地坪漆施工带来非常大的影响,如果不注意就会出现质量问题,例如环氧地坪漆漆膜起皱、起泡、麻点、针孔等现象。下面光磊环氧地坪漆厂家就给大家详细说明高温天气环氧地坪漆施工易出现的质量问题及处理方法。

    With the arrival of summer, the continuous high temperature weather becomes normal, and the temperature of most provinces and cities in our country is above 35 C. This high temperature weather has a great impact on the construction of epoxy floor paint. If we do not pay attention to it, there will be quality problems, such as wrinkling, blistering, pitting, pinholes and so on. The following Guanglei floor paint manufacturers will give you a detailed description of high temperature weather floor paint construction quality problems and treatment methods. 环氧地坪漆漆膜起皱现象

    Wrinkle Phenomenon of Epoxy Floor Paint Film1、起皱

    1. Wrinkle

    表现为环氧地坪漆漆膜呈现有规律的小波幅波纹形式的皱纹,有时可深及部分或全部膜厚。主要是因为温度过高,环氧地坪漆涂层里底和表层由于干燥速度不一样,高温下环氧地坪表层干燥速度加快,急剧收缩向上收拢,导致环氧地坪表面皱纹。也可能是施工中一次涂刷太厚,漆膜表面快速干燥,但内部未干,因而起皱。

    Wrinkles in the form of regular wave amplitude ripple on the epoxy floor paint film can sometimes be deep or partly or totally thick. The main reason is that the temperature is too high, because the drying speed of the inner and outer layers of the epoxy floor paint is different, the drying speed of the surface layer of the epoxy floor paint accelerates at high temperature, and shrinks sharply upward, resulting in wrinkles on the surface of the epoxy floor paint. It may also be that the coating is too thick in the construction, the surface of the paint film dries quickly, but the interior is not dry, so it wrinkles.

    处理方法:将起皱部位用铲刀铲去,再用粗砂纸打磨平整按正常环氧地坪漆施工工艺施工一至两遍。紧记要待第一层漆干透后,才可上第二层,但不宜涂得太厚。

    Processing method: Scrape the wrinkled part with a spade, then use coarse sand paper to grind and smooth it, and then apply it one or two times according to the normal construction technology of epoxy floor paint. Keep in mind that only after the first layer of paint is thoroughly dried, can the second layer be applied, but not too thick.


    环氧地坪漆漆膜起泡现象

    Foaming Phenomenon of Epoxy Floor Paint Film2、起泡

    2. Foaming

    起泡表现为油漆漆膜中存在气泡。主要是因为部分地坪漆涂料中含有自动分解释放气体的物质,搅拌也会在涂料中混入气体,温度过高,涂层在涂料中的气体释放出来之前固化,就会让气体留在涂层内,形成气泡。

    Foaming is manifested by the presence of bubbles in the paint film. The main reason is that some floor paint coatings contain substances that automatically decompose and release gases. Stirring will also mix gases in the paint. The temperature is too high. The coating solidifies before the gas in the paint is released, and the gas will remain in the coating and form bubbles.

    另外,涂料在施工过程中形成空气或溶剂挥发的气体造成气泡,在底材处理不当(如底材含水率高,毛孔未被封闭或基材表面有水等)或施工中涂刷不当(漆膜过厚等)时容易产生此现象。

    In addition, air or solvent volatile gas formed in the process of coating construction causes bubbles, which is easy to occur when the substrate is improperly treated (such as high moisture content of the substrate, pore is not sealed or there is water on the surface of the substrate) or improperly painted (paint film is too thick, etc.).

    处理方法:基材表面要处理干净,底材含水率不能太高,耐高温漆 如基材表面有水,要等水渍干透后再上油漆。如果已经产生气泡,可将有气泡处用铲刀铲去,重新打磨上漆。

    Processing method: The surface of the base material should be cleaned, the moisture content of the base material should not be too high. High temperature resistant paints such as water on the surface of the base material should be painted after the water is thoroughly dried. If air bubbles have been generated, the air bubbles can be shoveled off with a spade and repainted with paint.


    环氧地坪漆漆膜针孔、麻点现象

    Pinholes and pitting in epoxy floor paint film3、麻点、针孔

    3. Points and pinholes

    表现为油漆漆膜中存在着类似于针刺成的细孔。主要因为高温天气溶剂挥发速度加快,环氧地坪漆材料黏度过高,环氧地坪涂层中的气体在透过涂膜释放到涂层外时,会出现小孔,但因为涂料黏度高而无法自动消除,环氧地坪漆表面就会出现麻点、针孔。

    It is shown that there are fine holes in the paint film which are similar to those made by needling. The main reason is that the volatilization rate of solvent is accelerated in high temperature and the material viscosity of epoxy floor paint is too high. When the gas in epoxy floor coating is released to the outside of the coating through the coating, there will be small holes. But because of the high viscosity of the coating, it can not be eliminated automatically, and the surface of epoxy floor paint will appear pits and pinholes.

    处理方法:如是色漆砂磨后用腻子填平,再刷一至两遍即可。清漆打磨后薄刷几遍,让油漆渗入毛孔内填平为止。

    Processing method: If the paint is sanded and filled with putty, then brush it once or twice. Brush the varnish several times after polishing and let the paint penetrate into the pore until it is filled.


    正常的环氧地坪漆

    Normal epoxy floor paint夏季高温天气进行地坪漆施工的建议:

    Suggestions for floor paint construction in summer high temperature weather:

    1、尽量避免高温时段施工,可以采用早晚时段分叉施工。

    1. Avoid high temperature construction as far as possible. Bifurcation construction in morning and evening can be adopted.

    2、如果温度太高,可以采用人工降温措施,比如空调,水温降温等,但值得注意的是严谨将水及水渍浸入到材料中。

    2. If the temperature is too high, manual cooling measures can be adopted, such as air conditioning, water temperature cooling and so on, but it is worth noting that water and water impregnation are strictly immersed in the material.

    3、配料一次不宜太多,建议每次配漆应少量多次,选择沸点高的稀释剂。

    3. Ingredients should not be too many at one time. It is suggested that a small amount of diluents with high boiling point should be selected for each paint preparation.

    4、环氧底漆施工时,一定要密实均匀封底,千万不要漏涂,否则环氧地坪表面会出现针孔或者气泡。

    4. When epoxy primer is applied, it must be sealed tightly and evenly. Never leak out, otherwise pinholes or bubbles will appear on the surface of epoxy floor.
