廠家推薦七種方法檢測保定環氧地坪漆的性能

2021-12-21

保定環氧地坪漆性能指標試驗方法主要有以下幾種:一、容器中狀態:打開容器,手工攪拌,允許容器底部有部分沉淀。經攪拌易于混合均勻時,可定義為“攪拌后無硬塊”。二、耐水性:即測試保定環氧地坪漆涂膜對水的抵抗能力。測試方法:將保定環氧地坪漆施工在石棉板上,在規定的條件下,將石棉板浸泡在蒸餾水中,地坪漆涂膜的2/3在水中浸入水內,1/3在置于水面以上,浸泡96小時后,觀察涂膜表面是否有發白、失光、起泡、脫落等現象,如沒有則地坪漆通過測試。

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、耐堿性:即測試地坪漆涂膜對堿性物質的抵抗能力。測試方法:將地坪漆施工在石棉板上,在規定的條件下,將石棉板浸泡在一定濃度的堿液中,和耐水性測試方法一樣,地坪漆涂膜的2/3在水中浸入水內,1/3在置于水面以上,一般浸泡48小時后,觀察地坪漆涂膜是否有發白、失光、起泡、脫落等現象。

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:試驗方法:石棉水泥板兩塊(600㎜×600㎜),每塊板的一半環氧清漆均勻涂刷封閉層,干燥24H后,刷涂地坪涂料,該漆在整塊試板上應能分布均勻,并且伸展(滲散)良好時,可定為“刷涂后無刷痕,對底材無影響”。

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、對比率:又叫遮蓋力測試,即測試地坪漆對基面的遮蓋能力。測試方法:將地坪漆施工在黑白紙上,在規定的條件下,經反射率儀測試黑白紙上不同的反射率,即Rb和Rw,對比率=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:即測試地坪漆涂膜抵抗大氣灰塵的能力。測試方法:將地坪漆施工在石棉板上,先測試其反射率值A,然后在漆膜上涂刷0.7g的粉煤灰,干燥后,使用規定的實驗儀器沖刷漆膜,反復五次類同實驗,再次測試漆膜的反射率值B,則漆膜的耐污性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:保定環氧地坪漆老化有天然老化,也有人工加速老化的現象。如地坪漆涂膜暴露在戶外自然條件下而逐漸發生的性能變化.如褪色,粉化等即為地坪漆的天然老化,但由于測試時間很長,一般不具有可操作性。人工加速老化是指地坪漆涂膜經人工老化試驗機測試后,觀察保定環氧地坪漆漆膜所發生的變化,如粉化,變色.人工老化以hrs為單位,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.
