浅谈如何检测环氧地坪漆涂层的耐磨性能

耐磨性是涂层的机械性能之一,特别是在飞机、汽车、路标、地板、甲板等涂层中,在使用过程中经常因机械磨损而磨损。

工业厂房因其性能和优点而得到广泛应用。对于那些不知道这条线的人来说,各种性能都不清楚。现在我们可以简单地了解环氧地坪漆的耐磨性。根据国家标准GB1768-(79),规定了用薄膜耐磨仪器测定胶片性能的方法。它是由漆膜在一定载荷下的磨损和旋转次数和单位G(克)后的重量损失来表示的。环氧地坪涂料的耐磨性是膜干燥后抵抗摩擦的能力,即在遭受机械损伤时保持膜的性能。

常见的环氧地坪漆涂层耐磨性的测试步骤为:样板在特殊的圆形玻璃板上,通常为两次,间隔24h,试验板固定在耐磨装置的工作板上,以及LoA。在加压臂上增加了曲臂,降低了吸尘口,将样品板调整到1-1.5mm。打开开关并首先模拟50R(圆)以形成更平滑的表面。用刷子轻轻擦拭碎片,并第一次称量它。根据产品标准调整计数器。当达到所需的耐磨性时,它将立即停止。取出样品,擦掉残片,称重第二次。薄膜的质量和重量之间的差别是薄膜的失重。对于并行测试两次,每个值的误差不大于7%,并获得平均值。

Wear resistance is one of the mechanical properties of coatings, especially for coatings, such as aircraft, automobiles, road signs, floors, and decks, which are often worn by mechanical wear in the process of application.


Nowadays, the industrial floor is widely used because of its various properties and advantages. For those who do not know this line, it is not clear for all kinds of performance. Now we can simply understand the wear resistance of epoxy floor lacquer. According to the national standard GB1768-89 (79), the method of determining the performance of the film by the film wear-resistant instrument is stipulated. It is expressed by the weight loss of the lacquer film after the specified wear and rotation times under a certain load, and the unit G (gram). The wear resistance of the epoxy floor coating is the ability to resist the friction after the drying of the film, that is, to maintain the film performance when the mechanical damage is encountered.


The following are the testing steps of the wear resistance of the more common epoxy floor lacquer coatings: the sample books are on the special circular glass plate, usually two times, and the interval is 24h. The test plate is fixed on the working plate of the wear-resisting apparatus, and the loading arm is added on the pressurized arm, and the dust suction mouth is lowered, and the sample plate is adjusted to 1-1.5mm. Turn on the switch and first model the 50R (circle) to form a more smooth surface. Gently wipe off the scraps with a brush and weigh it for the first time. Adjust the counter according to the product standard. When the required wear resistance is achieved, it will stop immediately. Take out the sample, erase the scraps, weigh second times. The difference between the quality and the weight of the film is the weight loss of the film. For parallel test two times, the error of each value is not greater than 7%, and the average value is obtained.
