为什么要在使用山东彩钢复合板胶前进行处理?

为什么在使用山东彩钢复合板胶粘剂前必须处理好?

(1) 山东彩钢复合板胶接件表面处理前,有油污、脱膜剂、风化层、碳化层或锈层等,这些不干净、不牢固的表面层如不清除,将影响粘接性能。
(2) 山东彩钢复合板 例如,喷砂可以使抛光金属表面的粘合面积增加20倍。理论和实践证明,粗糙的表面能使固化胶与被粘物形成更紧密的网状结构。
(3) 山东彩钢复合板表面处理可以改善表面性能。例如,对金属表面进行化学处理,可以增加被粘物体表面的表面张力,从而提高粘接强度。对于一些难粘的低能表面,塑料和橡胶,只有经过表面处理(如用萘钠溶液处理四氟乙烯)才能进行有效的粘接,而用偶联剂进行表面处理也能提高粘接性能,因此表面处理在粘接中非常重要过程。
山东彩钢复合板黑白胶主要用于彩钢与不锈钢物体的粘接,以及建筑材料的粘接。随着这些行业的出现,彩钢黑白胶的使用量也在激增,这些行业都在推动这些黑白胶的使用效率,为了生产更多的工业产品,在一些加工领域也需要整顿,因此彩钢黑白胶的实用性能满足其生产需要。所以下面就简单介绍一下彩钢黑白胶的一些特点。
1 山东彩钢复合板它被用于工业生产的许多领域
在很多工业生产中,山东彩钢复合板黑白胶都是采用的,如彩钢行业、不锈钢行业和建材木业发展迅速。因此,虽然它是生产过程中的一个小物件,但却是必不可少的。它涉及到大量的工业生产,与工业生产密切相关。
2它克服了传统胶水韧性差的局限性
它的变化使胶水的韧性和强度满足了工人的需要。同时也克服了传统胶水解性能差的局限性,使现有胶具有更好的抗水解性能。这种胶水有很强的粘性。
三。不易衰老
用这种黑白胶涂在彩钢上,可以减缓老化,并在很大程度上保持其活性,使附着物保持更持久的粘结性。
4产品流动性好
胶水在使用过程中会不经意间被胶水的延伸挡住,但这种彩钢胶水并没有这种担心,因为它的光滑性能特别好。它不会被封锁。

Why is it necessary to deal with it before using Shandong color steel composite board adhesive?

(1) Before the surface treatment of the bonded parts, there are oil stain, film remover, weathering layer, carbonization layer or rust layer, etc. These unclean and unsound surface layers, if not removed, will affect the bonding performance.
(2) For example, sandblasting can increase the bonding area of the polished metal surface by 20 times. In addition, the rough surface can make the solidified adhesive form more meshing structure with the object to be adhered, which is proved by theory and practice.
(3) Surface treatment can improve the surface properties. For example, chemical treatment of metal surface can increase the surface tension on the surface of the object to be adhered, so as to improve the adhesive strength. For some hard to stick low-energy surfaces, plastics and rubber, effective bonding can only be carried out after surface treatment (such as using sodium naphthalene solution to treat tetrafluoroethylene), and the surface treatment with coupling agent can also improve the bonding performance So the surface treatment is very important in the bonding process.
Shandong color steel composite board black and white glue is mainly used in the adhesion of color steel and stainless steel objects, in addition to the adhesion of building materials. With the emergence of these industries, the use of color steel black and white glue is also surging, these industries are driving the use efficiency of these black and white, in order to produce more industrial products, in some processing areas also need to be rectified, so the practical characteristics of color steel black and white glue meet their production needs. So the following is a brief introduction to some characteristics of color steel black and white glue.
1. It is used in many fields of industrial production
In many industrial production, Shandong color steel composite board black and white glue is used, such as color steel industry, stainless steel industry and the rapid development of building materials wood industry. Therefore, although it is a small object in the production process, it is essential. It involves a lot of industrial production, which makes it closely related to industrial production.
2. It overcomes the limitation of poor toughness of traditional glue
Its change makes the tenacity and strength of glue meet the needs of workers. It also overcomes the limitation of the poor hydrolysis performance of traditional glue, making the current glue has better anti hydrolysis performance. This glue has a strong viscosity.
3. Not easy to aging
Using this kind of black and white glue for color steel, the aging will be slowed down, and its activity will be maintained to a great extent, so that the adhered objects will maintain more lasting cohesiveness.
4. The flow of the product is good
Glue in the use of the process will be inadvertently blocked by the glue extension, but this color steel glue does not have this worry, because its smooth performance is particularly good. It will not be blocked.
