    厂家从施工角度设计环氧自流平地坪

    环氧地坪涂料的配方设计不仅要满足涂膜性能的要求,还必须兼顾施工性能,应考虑到涂料在不同温度条件下对不同施工方式的可适应性和易操作性,对施工性能要求较高的环氧自流平地坪涂装更应如此。

    The formulation design of epoxy floor coatings should not only meet the requirements of coating performance, but also take into account the application performance. The adaptability and ease of operation of the coatings under different temperature conditions should be taken into account, especially for the epoxy self-leveling floor coatings with higher requirements for application performance.

    环氧自流平地坪施工温度:

    Construction temperature of epoxy self leveling floor:

    环氧地坪涂料的施工温度为5-35℃,但该温度区间对于不使用稀释剂的环氧自流平地坪涂料仍是很宽的温度范围。由于自流平环氧地坪涂料的黏度受温度影响很大,以至于低温下黏度合适的自流平环氧地坪涂料在高温施工会“像水一样流动”而难于镘涂施工。而高温下黏度适合的自流平地坪涂料在低温下则会粘稠得难以镘涂且表面不易流平。因而,环氧自流平地坪涂料一般需要设置冬用型和夏用型两种体系,以适应不同地域、不同季节的环境因素,尤其是温度因素的变化。

    The application temperature of epoxy floor coatings is 5-35 C, but this temperature range is still very wide for epoxy self-leveling floor coatings without diluents. Since the viscosity of self-leveling floor coatings is greatly affected by temperature, the self-leveling floor coatings with suitable viscosity at low temperature will "flow like water" at high temperature, which makes it difficult to apply. Self-leveling floor coatings with suitable viscosity at high temperatures will be too viscous to be applied at low temperatures and the surface will not be smooth. Therefore, epoxy self-leveling floor coatings generally need to set up two systems, winter and summer, to adapt to different geographical and seasonal environmental factors, especially the change of temperature factors.

    环氧自流平地坪施工方式:

    Construction method of epoxy self leveling floor:

    镘涂是环氧自流平地坪涂料传统的施工方法,也是目前常用的方法。镘涂施工的优点是操作简单,易于培训,但其施工效率较低,人工镘涂自流平面效率为300-500平方/8小时。镘涂施工受自流平涂料底剪切时表观黏度的影响很大,涂膜的厚度、施工的手感、长时间操作的疲劳程度都与涂料的黏度以及触变性有关。过大过小的黏度和触变性都会是涂料的镘涂施工变得困难。无气喷涂施工时涂料的流量取决于喷枪的动力和涂料的黏度。若涂料的黏度增大,则会降低喷枪的流量,降低施工效率。涂料的黏度低,既能够提高施工效率,有能够降低涂料的用量,并增加施工的自由度。

    Trowel coating is the traditional construction method of epoxy self leveling floor coating, and is also a commonly used method at present. The merits of upsetting are simple operation and easy training, but its construction efficiency is low. The surface efficiency of artificial upsetting is 300-500 square/8 hours. The thickness of coating film, the feeling of application and the fatigue degree of long-term operation are all related to the viscosity and thixotropy of the coating. Too large and too small viscosity and thixotropy will be difficult to paint the construction of the coating. The flow of paints depends on the power of the spray gun and the viscosity of the paint. If the viscosity of the coating increases, the flow rate of the spray gun will be reduced and the construction efficiency will be reduced. The low viscosity of the coating can improve the construction efficiency, reduce the dosage of the coating and increase the freedom of the application.
