    环氧地坪漆性能指标试验方法主要有以下几种:一、容器中状态:打开容器,手工搅拌,允许容器底部有部分沉淀。经搅拌易于混合均匀时,可定义为“搅拌后无硬块”。二、耐水性:即测试环氧地坪漆涂膜对水的抵抗能力。测试方法:将环氧地坪漆施工在石棉板上,在规定的条件下,将石棉板浸泡在蒸馏水中,地坪漆涂膜的2/3在水中浸入水内,1/3在置于水面以上,浸泡96小时后,观察涂膜表面是否有发白、失光、起泡、脱落等现象,如没有则地坪漆通过测试。

    The test methods of performance index of epoxy floor paint are mainly as follows: First, the state in the container: open the container, stir it manually, allowing partial precipitation at the bottom of the container. When stirring is easy to mix evenly, it can be defined as "no hard block after mixing". Two, water resistance: that is, testing the resistance of floor paint film to water. Test method: Apply floor paint on asbestos board, soak asbestos board in distilled water under specified conditions, 2/3 of the coating film is immersed in water, 1/3 is placed above the surface of water, after immersing 96 hours, observe whether the surface of the coating film is white, glossy, foaming, peeling off and other phenomena, if not, the floor paint passes through. Pass the test. 三、耐碱性:即测试地坪漆涂膜对碱性物质的抵抗能力。测试方法:将地坪漆施工在石棉板上,在规定的条件下,将石棉板浸泡在一定浓度的碱液中,和耐水性测试方法一样,地坪漆涂膜的2/3在水中浸入水内,1/3在置于水面以上,一般浸泡48小时后,观察地坪漆涂膜是否有发白、失光、起泡、脱落等现象。

    Three, alkali resistance: that is, testing the resistance of floor paint film to alkaline substances. Testing method: The floor paint is applied on asbestos board. Under the prescribed conditions, the asbestos board is immersed in a certain concentration of alkali solution. Like the water resistance testing method, 2/3 of the coating film of floor paint is immersed in water, 1/3 is placed above the water surface, and after soaking for 48 hours, whether the coating film of floor paint is white or glossy is observed. Bubbling, falling off and so on.

    四、刷涂性:试验方法:石棉水泥板两块(600㎜×600㎜),每块板的一半环氧清漆均匀涂刷封闭层,干燥24H后,刷涂地坪涂料,该漆在整块试板上应能分布均匀,并且伸展(渗散)良好时,可定为“刷涂后无刷痕,对底材无影响”。

    4. Brushing Property: Test Method: Two pieces of asbestos cement board (600 x 600), half of the epoxy varnish of each board is evenly coated with sealing layer, after drying for 24H, the paint should be evenly distributed on the whole board, and good extension (diffusion) can be defined as "no brush marks after brushing, no impact on the substrate." "."

    五、对比率:又叫遮盖力测试,即测试地坪漆对基面的遮盖能力。测试方法:将地坪漆施工在黑白纸上,在规定的条件下,经反射率仪测试黑白纸上不同的反射率,即Rb和Rw,对比率=Rb/Rw(如:0.87、0.90、0.93、0.95等)。

    Five, contrast ratio: also known as cover test, that is, testing the ability of floor paint to cover the base surface. Test method: The floor paint is applied on black and white paper. Under the prescribed conditions, the reflectivity of black and white paper is tested by reflectometer, that is, Rb and Rw, and the contrast ratio is Rb/Rw (e.g. 0.87, 0.90, 0.93, 0.95, etc.).

    六、耐污性:即测试地坪漆涂膜抵抗大气灰尘的能力。测试方法:将地坪漆施工在石棉板上,先测试其反射率值A,然后在漆膜上涂刷0.7g的粉煤灰,干燥后,使用规定的实验仪器冲刷漆膜,反复五次类同实验,再次测试漆膜的反射率值B,则漆膜的耐污性X=(A-B)/A(如:20%、15%、10%)。

    Six, stain resistance: that is, testing the ability of floor paint film to resist atmospheric dust. Test method: Apply floor paint on asbestos board, test its reflectivity value A first, then brush 0.7G fly ash on the paint film, after drying, wash the paint film with the prescribed experimental instrument, repeat the same experiment five times, test the reflectivity value B again, then paint film anti-fouling X=(A-B)/A (e.g., 20%, 15%, 10%).

    七、耐老化:环氧地坪漆老化有天然老化,也有人工加速老化的现象。如地坪漆涂膜暴露在户外自然条件下而逐渐发生的性能变化.如褪色,粉化等即为地坪漆的天然老化,但由于测试时间很长,一般不具有可操作性。人工加速老化是指地坪漆涂膜经人工老化试验机测试后,观察环氧地坪漆漆膜所发生的变化,如粉化,变色.人工老化以hrs为单位,如250hrs、400hrs、600hrs等。

    Seven, aging resistance: epoxy floor paint aging has natural aging, also has the phenomenon of artificial accelerated aging. For example, the natural aging of floor paint is caused by the gradual change of the performance of the coating film exposed to natural outdoor conditions, such as fading, powdering, etc. However, due to the long testing time, it is generally not operable. Artificial accelerated aging refers to the observation of changes in the film of epoxy floor paint, such as pulverization and discoloration, after being tested by an artificial aging machine.
