使用济南复合板胶粘之前为何进行处理?

来源:http://www.jnjgcg.com/ 日期:2020-11-20 发布人:jiangucaigang
济南彩钢复合板的黑白胶主要用于彩钢和不锈钢物体的粘接,此外还用于建筑材料的粘接。 随着这些行业的突然出现,彩钢黑白胶的使用也是风起云涌,带动了这些黑白的使用效率。
The black and white glue of Jinan color steel composite board is mainly used for the bonding of color steel and stainless steel objects, as well as the bonding of building materials. With the sudden emergence of these industries, the use of color steel black and white glue is also surging, driving the use efficiency of these black and white.
(1)济南复合板表面处理前,胶粘部位经常有油污、脱模剂、风化层、碳化层或锈层等。如果这些不干净和不稳定的表面层没有被去除,粘合性能将受到影响。
(1) Before the surface treatment of Jinan composite board, there are oil stain, release agent, weathering layer, carbonization layer or rust layer. If these unclean and unstable surface layers are not removed, adhesion will be affected.
(2)被粘物表面的粗颗粒处理可以增加被粘物的实际粘结面积。例如,喷砂可以将抛光金属表面的结合面积增加20倍。此外,粗糙的表面可以使固化后的胶粘剂与被粘物形成更多的啮合结构——机械结合力,提高结合强度,这一点已被理论和实践所证明。
(2) Coarse particle treatment on the surface of the adherent can increase the actual bonding area of the adherent. For example, sandblasting can increase the bonding area of polished metal surfaces by 20 times. In addition, the rough surface can make the cured adhesive form more meshing structure with the adherent, which has been proved by theory and practice.

(3)表面处理可以提高表面性能,如金属表面的化学处理,可以提高被粘物表面的表面张力,从而提高粘接强度。一些低能量的难以粘接的表面,塑料和橡胶,经过表面处理(如用萘钠溶液处理四氟乙烯)后可以有效粘接,用偶联剂进行表面处理也可以提高粘接性能,所以表面处理在材料粘接过程中非常重要。
(3) Surface treatment can improve the surface properties, such as the chemical treatment of metal surface, which can improve the surface tension of the adherent surface, so as to improve the bonding strength. Some low-energy hard to bond surfaces, plastics and rubber, after surface treatment (such as sodium naphthalene solution treatment of tetrafluoroethylene) can be effectively bonded, using coupling agent for surface treatment can also improve the bonding performance, so surface treatment is very important in the bonding process of materials.
