    夏季环氧地坪漆施工中易起泡的原因和预防办法

    2018-10-27 08:45:54 无锡盛发地坪科技有限公司 阅读

    炎热的夏季悄然来袭,环氧地坪漆施工工程紧锣密鼓进行中。但是,在越来越热的天气下,由于环氧地坪漆施工中操作不当,可能会引起很多问题。比如环氧地坪施工中产生气泡问题,那么产生的原因是什么?又有什么解决的方法呢?

    The hot summer is coming quietly, and the construction works of epoxy floor paint are in full swing. However, in the increasingly hot weather, due to improper operation of floor paint construction, may cause many problems. For example, what happens in the construction of floors is the problem of bubbles. What are the solutions? 1、夏季温度过高,造成环氧地坪漆软化,粘结力大大降低;

    1, the summer temperature is too high, resulting in the epoxy floor paint softening, the bonding force is greatly reduced.

    2、雨后地面潮湿,含水量高,水汽不能排除;

    2. After the rain, the ground is humid, and the water content is high.

    3、施工人员涂刷底漆时,与基层结合不好有空隙等。

    3. When the construction workers are painting primers, there is no gap between them.

    为防止环氧地坪层起泡,必须杜绝水、暴晒和灰尘。

    To prevent foaming in epoxy floor, water, exposure and dusts must be eliminated.

    环氧地坪漆公司预防办法

    Preventive measures for epoxy floor paint company

    ①地面基层做好防水层,控制基层或者防水层内的水分不超过8%,抗压强度大于20Mpa,然后进行地坪漆施工。

    The ground base should be waterproof layer, control the moisture content of the base or waterproof layer not to exceed 8%, and the compressive strength is more than 20 Mpa. Then the floor paint construction should be carried out.

    ②提高环氧层和基层间的粘结力,避免水泡产生;

    (2) increasing the cohesive force between epoxy layer and base layer to avoid blistering.

    ③涂刷底漆时,精细打磨除尘后,涂刷底漆量要足,避免露低现象发生;

    3. When the primer is painted, the amount of primer should be enough to avoid the phenomenon of low dew after fine grinding.

    ④地坪工程施工完毕后,避免阳光照晒,确保温度在35度以下;

    4. After the construction of the floor project is finished, avoid the sun to shine on the sun to ensure that the temperature is below 35 degrees.


    环氧地坪基层做防水,在防水材料在选用上必须具备以下几点:

    Epoxy floor for waterproofing, in the selection of waterproof materials must have the following points:

    1)抗渗不透气性;

    1) impermeability and permeability.

    2)抗压性,强度大于20MPa;

    2) compressive strength, strength is greater than 20MPa;

    3)和地面有超强的粘接性;

    3) strong adhesion to the ground.

    4)和环氧树脂容易粘接形成一个整体。另外,防水层在施工完工后3天内不得上人受重压等,保护好成品。

    4) it is easy to bond with epoxy resin to form a whole. In addition, the waterproof layer should not be heavily stressed during the 3 days after completion of construction, so as to protect the finished product.

    环氧树脂地坪的面层既满足客户的使用功能要求(如防尘、防腐、防静电等),对地面又具有装饰效果。但在施工过程中或施工完成后,面层会容易产生变白失光的问题。

    The surface of epoxy resin floor not only meets the customer's functional requirements (such as dust proof, anti-corrosion, anti-static, etc.), but also has decorative effect on the floor. However, during the construction process or after construction, the surface layer will easily produce the problem of whitening and losing light.

    地坪涂装施工中的白化(泛白、发白)难题指的是涂装过程中和刚涂装完毕的涂层表面涂膜呈乳白色,类似云彩那样变白失光的现象。多发生在涂装挥发性地坪涂料的场合,严重时完全失光。涂膜上出现微孔,力学性能下降。

    The whitening (whitening, whitening) problem in the construction of floor coating refers to the phenomenon that the film on the surface of the coating is milky white during the coating process and just after the coating is finished, which is similar to that of clouds. It often occurs on the occasions of coating the volatile floor coating, and is completely lost light when serious. Micropores appeared on the coating and mechanical properties decreased.

    为什么会产生这种情况?我们该如何预防这种现象的发生?

    Why does this happen? How can we prevent such a phenomenon from happening?

    产生以上现象的原因:

    The reasons for these phenomena are:

    1、涂膜在干燥中,由于所用的有机溶剂的沸点低、挥发太快,降低了涂膜的表面温度,就会使部分水汽凝积在涂膜的表面形成白雾状,引起涂膜浑浊和失光。

    1. In the drying process, because the boiling point of the organic solvents used is low and the volatilization is too fast, the surface temperature of the film will be reduced, and part of the water vapor will condense on the surface of the film to form a white mist, causing the film to be turbid and dull.

    2、施工场所空气温度太高(相对温度超过80%)。涂料和稀释剂中含水,或压缩空气带入水分。

    2. The air temperature in the construction site is too high (relative temperature exceeds 80%). Water in paint and diluent or compressed air leads to moisture.

    3、快干漆施工中使用大量低沸点的稀释剂,涂膜不但会发白,有时也会出现多孔状和细裂纹。凝积在湿膜上的水汽,会使漆膜中的树脂或高分子聚合物部分析出,而引起涂膜发白会使漆膜中的树脂或高分子聚合物部分析出,而引起涂膜发白。

    3. A large number of diluents with low boiling point are used in the construction of fast-drying paint. The film will not only whiten, but also appear porous and fine cracks sometimes. The water vapor accumulated on the wet film will cause the resin or polymer part of the film to precipitate, and the whitening of the film will cause the resin or polymer part of the film to precipitate, and cause the film to whiten.

    环氧地坪涂料漆膜泛白的防治方法:

    Prevention and treatment of whitening film on epoxy floor coatings:

    (1)添加防潮剂,注意施工场地的环境温度和湿度。

    (1) add moisture-proof agent, pay attention to construction site temperature and humidity.

    (2)涂装场地的环境温度控制在15-25℃,相对湿度不高于70%。

    (2) the ambient temperature of the painting site is controlled at 15-25 C, and the relative humidity is not higher than 70%.

    (3)防止通过溶剂和压缩空气带入水分。

    (3) prevent moisture from being carried through solvent and compressed air.

    (4)快干漆施工中应选用配套稀释剂,而且稀释剂的用量也不宜过多。

    (4) suitable diluent should be selected for quick drying lacquer construction, and the amount of diluent should not be excessive.

    (5)可在涂料中加入适量的防潮剂(防白剂)或丁醇类增水剂。

    (5) a suitable amount of moisture-proof agent (butanol) or butanol type superplasticizer can be added to the coating.

    (6)涂装前使被涂件的温度高于环境(10℃左右)。

    (6) the temperature of the coated part before coating is higher than that of the environment (around 10 degrees Celsius).

    (7)对涂装场所进行适当的加热,升高涂装环境温度。

    (7) heating the coating site appropriately and raising the temperature of the coating environment.

    (8)使用质量好、挥发较慢的稀释剂。

    (8) use diluent with good quality and slow volatilization.
